    JOSEPH M. BOOTH v. PARK TERRACE II MUTUAL
    HOUSING LIMITED PARTNERSHIP ET AL.
    (AC 45094)
    Alvord, Prescott and Moll, Js.
    Syllabus
    The plaintiff sought to recover damages for injuries he sustained when he
    allegedly tripped and fell on a concrete walkway separating the lawns
    of two buildings on a property owned by the defendants P Co. and M
    Co. The defendants C Co. and T Co. were hired to work on a rehabilitation
    project on the property. The plaintiff alleged that he tripped on the
    raised edge of the walkway, which was perpendicular to and abutted
    the front sidewalk between the two buildings. He claimed that the raised
    edge created a hazardous condition. During the pretrial proceedings, P
    Co. and M Co. served the plaintiff with a request for admission pursuant
    to the applicable rule of practice (§ 13-22). The request stated that an
    attached photograph fairly and accurately depicted the location of the
    plaintiff’s fall, and that the alleged proximately causative defect of the
    claimed fall as asserted in the complaint was encircled in red on the
    photograph. The plaintiff did not answer or object to the request for
    admission, and the request for admission was deemed admitted. There-
    after, P Co. and M Co. filed an expert witness disclosure, which repre-
    sented that the expected testimony of their expert, C, was that the
    plaintiff’s fall did not occur on their property but on land owned by the
    city of Hartford. Subsequently, the defendants filed motions for summary
    judgment, claiming, inter alia, that the plaintiff’s fall occurred on a public
    sidewalk owned and maintained by the city of Hartford and that they
    had no legal duty to maintain or repair the sidewalk. In support thereof,
    they attached an affidavit of C, who averred that he had performed a
    comprehensive land survey of the property and that the area circled on
    the photograph attached to the request for admission was not private
    property of the abutting owner but was a public sidewalk owned and
    maintained by the city of Hartford. The defendants further argued that
    the exceptions to the general rule absolving property owners of liability
    for defective public sidewalks were not applicable, as there was no
    ordinance shifting responsibility to the abutting landowner and the plain-
    tiff’s complaint had not alleged any ‘‘positive act’’ on behalf of the
    defendants that created a defect. The plaintiff filed objections to the
    motions for summary judgment, claiming that genuine issues of material
    fact existed as to whether he fell on property owned by P Co. and M
    Co. and whether C Co. and T Co. were contracted to repair and renovate
    the walkway at issue and the abutting sidewalk, thus engaging in a
    positive act. Thereafter, the plaintiff filed a request to amend the revised
    complaint, in which he sought to include additional allegations as to
    the construction, maintenance, and renovations by the defendants. The
    trial court denied the plaintiff’s request to revise and granted the defen-
    dants’ motions for summary judgment. On the plaintiff’s appeal to this
    court, held:
    1. The trial court properly granted the defendants’ motions for summary
    judgment, that court having properly determined that there were no
    genuine issues of material fact:
    a. The trial court properly concluded that there were no genuine issues
    of material fact with respect to the extent and location of the defective
    condition that caused the plaintiff’s alleged fall: the location of the plain-
    tiff’s fall was conclusively established by the request for admission;
    moreover, the plaintiff’s claim that the admission established, at most,
    the location of the fall, and not the defective condition that caused the
    fall, was unavailing, as the court properly relied on the admission as
    conclusively establishing that the alleged defect was contained with the
    red circled area of the photograph.
    b. The trial court properly concluded that the plaintiff, as the opposing
    party, failed to present evidence demonstrating the existence of some
    disputed factual issue as to the ownership or maintenance of the area
    in which he allegedly fell: the plaintiff’s submissions of sidewalk citation
    and correction records, a demolition plan, and a renovation and repair
    plan, did not create a genuine issue of material fact as to whether the
    defendants were responsible for keeping the abutting sidewalk in a
    safe condition, as the citation and correction records related to other
    properties and not to the property at issue, the demolition plan contained
    print so small and blurry as to be practically unreadable and, although
    the text of that plan failed to explicate the technical design plans, the
    plaintiff failed to support his opposition with affidavits or deposition
    testimony of fact witnesses with personal knowledge of the plans or the
    property, and the renovation and repair plan documents were dated after
    the date of the plaintiff’s fall and none of the extensive textual notes or
    legends on the plan documents were legible; moreover, representations
    by the plaintiff’s counsel as to what was depicted in and the significance
    of the text in the demolition plan was not evidence.
    c. Contrary to the plaintiff’s contention, the operative complaint did not
    allege any positive acts by the defendants involving the area where the
    plaintiff fell to bring his claims within the positive act exception to the
    common-law rule that an abutting landowner is under no duty to keep
    the public sidewalk in front of its property safe: the plaintiff did not
    allege that the defendants constructed the walkway or abutting sidewalk
    nor did he allege that they undertook any positive act with respect to
    the walkway or abutting sidewalk, rather, the plaintiff alleged that the
    defendants failed to take affirmative steps to remediate the defective
    condition; moreover, the allegation that there existed a walkway that
    was raised higher than the abutting sidewalk could not be construed as
    alleging that the defendants, through a positive act, caused the defect
    in the sidewalk.
    2. The trial court did not abuse its discretion in denying the plaintiff’s request
    to amend his revised complaint: that court properly found that permitting
    the amendments would prejudice the defendants in that it would alter
    the substance of the plaintiff’s claim while the motions for summary
    judgment were pending, the motions having already been fully briefed
    by all parties, and oral argument on those motions having already been
    scheduled; moreover, the plaintiff’s claims that he did not assert new
    counts of liability and that his delay in obtaining documents from the
    city of Hartford was not unreasonable due to limited access to the city
    hall during the pandemic were unavailing, as the trial court properly
    determined that permitting the amendments would prejudice the defen-
    dants by requiring additional discovery and occasion further delay.
    3. This court declined to review the plaintiff’s claim that the trial court
    abused its discretion in denying his motion to preclude the expert wit-
    ness affidavit offered by P Co. and M Co. in support of their motion for
    summary judgment: the plaintiff’s claim was inadequately briefed, as he
    devoted only one paragraph of his brief to this claim, and he provided
    no analysis in support of his argument.
    Argued November 8, 2022—officially released January 31, 2023
    Procedural History
    Action to recover damages for personal injuries sus-
    tained as a result of the defendants’ alleged negligence,
    and for other relief, brought to the Superior Court in
    the judicial district of Tolland, where the defendants
    filed motions for summary judgment; thereafter, the
    court, Parkinson, J., denied the plaintiff’s request to
    amend the complaint and his motion to preclude the
    expert witness affidavit of the named defendant et al.;
    subsequently, the court, Parkinson, J., granted the
    defendants’ motions for summary judgment and ren-
    dered judgment thereon, from which the plaintiff
    appealed to this court. Affirmed.

    Opinion
    ALVORD, J. The plaintiff, Joseph M. Booth, appeals
    from the judgment of the trial court granting motions
    for summary judgment filed by the defendants, Park
    Terrace II Mutual Housing Limited Partnership and
    Mutual Housing Association of Greater Hartford, Inc.
    (collectively, owner defendants), and Crosskey Archi-
    tects, LLC, and TO Design, LLC (collectively, design
    defendants), and denying the plaintiff’s request to
    amend his complaint and his motion to preclude expert
    testimony. On appeal, the plaintiff claims that the court
    (1) improperly rendered summary judgment because
    genuine issues of material fact exist, (2) abused its
    discretion in denying his request to amend his com-
    plaint, and (3) abused its discretion in denying his
    motion to preclude the expert affidavit offered in sup-
    port of the owner defendants’ motion for summary judg-
    ment. We disagree and, accordingly, affirm the judg-
    ment of the trial court.
    The following procedural history is relevant to our
    analysis of the plaintiff’s claims. On or about April 24,
    2018, the plaintiff allegedly tripped and fell on a walk-
    way separating the lawns of 286 and 290 Park Terrace
    in Hartford. In April, 2020, the plaintiff commenced
    this action against the owner defendants, owners of
    property located at 286 and 290 Park Terrace, and the
    design defendants, who were retained to work on a
    rehabilitation project at 286 and 290 Park Terrace. The
    operative complaint, which is the revised complaint
    filed on October 22, 2020,1 contains six counts sounding
    in negligence and premises liability.
    In counts one and two, the plaintiff alleged that the
    owner defendants ‘‘owned or were in control of and/
    or had a duty to maintain the walkway and surrounding
    areas where the plaintiff fell.’’ The plaintiff alleged that
    he tripped and fell on the walkway separating the lawns
    of 286 and 290 Park Terrace. Specifically, he alleged
    that his ‘‘left foot caught the raised edge of the concrete
    walkway that leads to the rear parking lot. That walk-
    way is perpendicular to and abuts the front sidewalk
    between 286 and 290 Park Terrace . . . . The concrete
    walkway is raised higher than the abutting sidewalks
    creating a hazardous condition which led to [the plain-
    tiff’s] fall.’’ The plaintiff set forth nine allegations of
    negligence that he contended caused his injuries: the
    owner defendants ‘‘failed to lower the walkway so that
    it was level with the abutting sidewalks . . . failed to
    position the slab of the walkway so that it was level
    with the abutting sidewalks . . . failed to shave down
    the slab of the walkway so it was not higher than the
    abutting sidewalks . . . failed to maintain the property
    in a reasonably safe condition . . . failed to warn the
    plaintiff of the dangerous condition . . . breached
    [their] duty to inspect [their] property from time to time
    to make sure that no hazards or defects existed or if a
    dangerous condition existed . . . failed to inspect
    [their] property . . . the conditions had existed for an
    unreasonable period of time, yet the defendant[s] had
    taken no measure to remedy or correct them; and . . .
    [they] knew or in the exercise of reasonable care and
    inspection should have known of these conditions and
    should have taken measures to remedy and correct
    them, but the defendant[s] carelessly and negligently
    failed to do.’’ The plaintiff alleged, inter alia, that he
    sustained physical injuries, he has undergone serious
    medical treatment, his ability to enjoy and participate
    in life’s activities has been severely diminished, and he
    has lost wages.
    In counts three and four, the plaintiff alleged that
    ‘‘[a]t all times hereto’’ the design defendants were hired
    to rehabilitate certain properties on Park Terrace,
    including property located at 286 and 290 Park Terrace.
    He alleged that the design defendants were ‘‘responsible
    for the construction means, methods, techniques,
    sequences and/or procedures of the rehabilitation.’’ He
    alleged that the design defendants ‘‘owned, possessed,
    controlled or had an interest in and/or [were] responsi-
    ble for the maintenance and/or rehabilitation of the
    properties located at 286 . . . and 290 Park Terrace.’’
    He alleged that the design defendants were responsible
    for maintaining the walkway and surrounding areas
    where the plaintiff fell. He further alleged that the
    design defendants ‘‘reviewed and surveyed the prop-
    erty,’’ but failed to or ‘‘did not recommend that the
    raised edge of the slab where the plaintiff tripped be
    repaired and/or modified.’’ In addition to the nine allega-
    tions of negligence set forth against the owner defen-
    dants, the plaintiff alleged that the design defendants
    ‘‘did not place markers or flags to warn the plaintiff of
    [the] defective condition.’’
    In counts five and six, the plaintiff alleged that ‘‘[o]n
    or about April 24, 2018, and at some time prior thereto,’’
    the design defendants were ‘‘hired to design and/or
    work a rehabilitation plan so that invitees would be
    able to safely walk on the walkway and surrounding
    areas at the property.’’ He alleged that the design defen-
    dants were negligent in that ‘‘[they] failed to design the
    rehabilitation plan so that the walkway was level with
    the abutting sidewalks . . . failed to design the rehabil-
    itation plan so that [the] position of the slab of the
    walkway was level with the abutting sidewalks . . .
    failed to design the rehabilitation plan so that the slab
    of the walkway was not higher than the abutting side-
    walk . . . failed to design the rehabilitation plan so
    that the property was in a reasonably safe condition
    . . . failed to design the rehabilitation plan so that [the]
    plaintiff was warned of the dangerous condition . . .
    breached [their] duty to inspect the property from time
    to time to make sure that no hazards or defects existed
    or if a dangerous condition existed . . . failed to
    inspect the property . . . the conditions had existed
    for an unreasonable period of time, yet [they] had taken
    no measure to remedy or correct them . . . knew or
    in the exercise of reasonable care and inspection should
    have known of these conditions and should have taken
    measures to remedy and correct them, but [they] care-
    lessly and negligently failed to do . . . failed to observe
    or inspect work in place.’’2
    In November, 2020, the owner defendants served the
    plaintiff with a request for admission pursuant to Prac-
    tice Book § 13-22. The request stated: ‘‘At the time and
    place referenced in [the] plaintiff’s complaint, the pho-
    tograph attached to Request for Admission #1 of Octo-
    ber 20, 2020 (#109), which is marked as ‘Exhibit A’ and
    dated May 24, 2018, fairly and accurately depicts the
    location of the plaintiff’s claimed fall, and the alleged
    proximately causative defect of the claimed fall as
    asserted in the complaint, is encircled in red in that
    Exhibit A’’3 (request for admission). The plaintiff did
    not answer or object to the request for admission. As
    a result of the plaintiff’s failure to respond, the request
    for admission was deemed admitted. See Practice Book
    § 13-23 (a).4
    On April 26, 2021, the owner defendants filed an
    expert witness disclosure, in which they disclosed Ken-
    neth R. Cyr, a professional land surveyor and principal
    of Flynn & Cyr Land Surveying, LLC, a company which
    had performed a survey of the property (Cyr survey
    map). The disclosure stated that Cyr’s expected testi-
    mony was ‘‘based on his education, training and experi-
    ence, based on his personal familiarity with the property
    at issue in this case and its boundaries, based upon the
    [Cyr survey map], and based upon the Survey Map and
    Zoom-in Survey Map of the subject property, provided
    to all counsel of record at the time of this disclosure
    of expert.’’ The disclosure represented that ‘‘[i]t is the
    opinion of Mr. Cyr that the alleged fall in this case did
    not occur on the property of these defendants, but on
    city of Hartford owned land.’’
    In April, 2021, the owner defendants also filed a joint
    motion for summary judgment and memorandum of
    law in support of that motion. Therein, they argued that
    the plaintiff’s alleged fall occurred on a public sidewalk
    owned and maintained by the city of Hartford. In sup-
    port of that contention, the owner defendants attached
    an affidavit of Cyr, who averred that he and his firm
    had performed a comprehensive land survey of the
    property. Cyr averred that he carefully had reviewed
    the survey map and the photograph that was attached
    to the request for admission. Cyr averred that the ‘‘area
    within the red circle on that photograph, Exhibit A, is
    not private property of the abutting owner; rather, it is
    very clearly public sidewalk based on the Survey Map.
    The area encircled in red on Exhibit A is within the
    public right-of-way. . . . That area within the red circle
    on the photograph, is owned and maintained by the
    [c]ity of Hartford, and not by the abutting landowner.’’
    (Emphasis omitted.)
    On the basis of the foregoing evidence, the owner
    defendants argued that the alleged fall occurred within
    the public right-of-way, not on private property, and
    that, therefore, they had no legal duty to maintain or
    repair the sidewalk. They further argued that the excep-
    tions to the general rule absolving property owners of
    liability for defective public sidewalks were not applica-
    ble, as there was no ordinance shifting responsibility
    to the abutting landowner and the plaintiff’s complaint
    had not alleged any ‘‘positive act’’ on behalf of the
    defendants that created a defect.
    The design defendants also filed a joint motion for
    summary judgment and memorandum of law in support
    of their motion, in which they represented that they
    joined fully in the motion for summary judgment, mem-
    orandum of law, and supporting exhibits filed by the
    owner defendants. The design defendants reiterated the
    owner defendants’ arguments, arguing that they had no
    duty to maintain property owned by the city of Hartford
    and that the plaintiff had alleged no positive act by
    them.
    On July 2, 2021,5 the plaintiff filed objections to the
    defendants’ motions for summary judgment. The plain-
    tiff asserted that the owner defendants ‘‘constructed
    the abutting sidewalk, repaired it, maintained it, and
    have corrected various sidewalk citations relating to the
    abutting sidewalk.’’ The plaintiff argued that genuine
    issues of material fact existed with respect to whether
    the plaintiff fell on the owner defendants’ property or on
    an abutting sidewalk; whether the hazardous condition
    consisted of the entire walkway, which he contended
    was steeply sloped, or only the raised lip at the end of
    the walkway; whether the owner defendants, in con-
    structing both the walkway and the abutting sidewalk
    and correcting various sidewalk citations issued by the
    city, had engaged in positive acts that imposed a duty
    on the owner defendants; and whether the owner defen-
    dants, in constructing the walkway and the abutting
    sidewalk and correcting the sidewalk citations, had pos-
    session and control over the area in which the plain-
    tiff fell.
    The plaintiff further argued that the following docu-
    ments demonstrated genuine issues of material fact: a
    Survey and Demolition Plan dated May 8, 2001 (2001
    demolition plan) purportedly showing that the owner
    defendants undertook substantial renovation and reha-
    bilitation work on the property, which the plaintiff con-
    tended included constructing the subject walkway and
    the entire abutting sidewalk; sidewalk citation and cor-
    rection records; and a layout and demolition plan dated
    April 25, 2018 (2018 renovation and repair plan), which
    the plaintiff contended included repairing walkways
    and the abutting sidewalk. In support of his objection
    to the owner defendants’ motion for summary judg-
    ment, the plaintiff filed his own affidavit, in which he
    averred that he had obtained the 2001 demolition plan,
    the 2018 renovation and repair plan, and the sidewalk
    citation and correction records from the city or its web-
    site and part of the 2018 renovation and repair plan from
    his employer during the course of his employment.6 The
    plaintiff’s affidavit also stated: ‘‘I believe that based
    on the evidence submitted, my fall occurred on the
    [w]alkway maintained and controlled by [the] defen-
    dants and/or their agents, and that their negligence
    caused the hazardous condition that resulted in my
    substantial injuries.’’ He also submitted other docu-
    ments as exhibits in support of his objection to the
    owner defendants’ motion for summary judgment.
    In his objection to the design defendants’ motion for
    summary judgment, which was not accompanied by
    any affidavits or exhibits, the plaintiff asserted that
    genuine issues of material fact included: whether the
    design defendants, having been contracted to repair
    and renovate the walkway and abutting sidewalk,
    engaged in a positive act over the abutting sidewalk;
    whether the design defendants had possession and con-
    trol over the walkway and/or abutting sidewalk;
    whether the design defendants, through their repair and
    renovation work on the walkway and abutting sidewalk,
    created the hazardous condition that caused the plain-
    tiff’s trip and fall; whether the design defendants failed
    to warn the plaintiff of the hazardous condition that
    they knew or should have known about; and the extent
    and scope of the hazardous condition, whether it was
    the entire walkway and its steep slope, or limited to
    the end slab of the walkway with its raised lip. The
    plaintiff also asserted that the design defendants failed
    to warn him of the hazardous condition and argued that
    the design defendants had failed to respond to this
    allegation of negligence.
    On July 7, 2021, the defendants filed replies to the
    plaintiff’s objections. The owner defendants argued that
    the plaintiff’s affidavit was insufficient to authenticate
    the documents that he filed as exhibits, which contained
    hearsay, and that the affidavit was inadmissible to the
    extent that the plaintiff asserted, without personal
    knowledge, that he ‘‘believe[d]’’ that he fell on property
    ‘‘maintained or controlled by the defendants.’’ The
    owner defendants further argued that the plaintiff had
    failed to plead any alleged defect in the slope of the
    walkway or any positive acts of the defendants. The
    design defendants reiterated these arguments and addi-
    tionally argued that, even if the court determined that
    the exhibits filed in support of the plaintiff’s objection
    and affidavit were admissible, the exhibits failed to
    demonstrate a genuine issue of material fact.
    Oral argument on the motions for summary judgment
    was scheduled for July 7, 2021. On that date, the parties
    appeared before the court and the plaintiff’s counsel
    orally requested an additional two week continuance
    of oral argument and to file a surreply brief.7 The court
    granted the plaintiff’s requests and the defendants’
    ensuing request to file an additional surreply following
    the plaintiff’s surreply. The court rescheduled oral argu-
    ment for August 12, 2021.
    In his surreply, the plaintiff not only argued that his
    original submissions were sufficient to demonstrate a
    genuine issue of material fact, but he also submitted
    his amended affidavit together with copies, certified
    by city officials, of the 2001 demolition plan, the 2018
    renovation and repair plan, and the sidewalk citation
    and correction records. With respect to his complaint,
    he argued in his surreply that the operative complaint
    alleged that the entire walkway constituted the hazard-
    ous condition and that the defendants had engaged in
    positive acts, but he also filed a request to amend his
    complaint to ‘‘conform such allegations to the evidence
    recently discovered . . . that the defendants did in fact
    construct the abutting sidewalk, walkway, and maintain
    them.’’8 Last, he noted in his surreply that he had sought
    to depose the owner defendants’ expert, but that the
    owner defendants had filed a motion for protective
    order. In his surreply directed to the design defendants,
    the plaintiff additionally argued that these defendants
    knew of the hazardous condition as evidenced by their
    plans including a correction to the slope of the abutting
    sidewalk and walkway. The plaintiff argued that the
    design defendants failed to adequately identify and
    warn the plaintiff of the hazard.
    The defendants filed surreplies to the plaintiff’s surre-
    ply. The owner defendants reiterated that there was no
    genuine issue of material fact that the plaintiff’s claimed
    fall occurred on a city sidewalk. The design defendants
    argued, inter alia, that they did not ‘‘have a duty of care
    to identify hazardous conditions outside the property
    boundaries,’’ i.e., on the public sidewalk. They further
    argued that the 2018 renovation and repair plan is dated
    after the date of the plaintiff’s alleged fall and, therefore,
    it could not form the basis of any positive act on behalf
    of the design defendants. Oral argument was held on
    August 12, 2021.
    On October 14, 2021, the court granted the defen-
    dants’ motions for summary judgment, rendering sum-
    mary judgment in favor of the defendants on all counts.
    In its memorandum of decision, the court first deter-
    mined that the defendants had satisfied their initial
    burden as movants for summary judgment. The court
    discussed the owner defendants’ request for admission
    and the plaintiff’s failure to respond thereto. The court
    determined that ‘‘it has been conclusively established
    that the photo[graph] marked in exhibit A of the request
    for admission fairly and accurately depicts the location
    of the plaintiff’s fall and the alleged defect is contained
    within the red encircled area of the photograph.’’ The
    court also summarized Cyr’s affidavit, in which Cyr
    averred that the ‘‘area within the red circle in [e]xhibit
    A of the defendant’s request for admission is not private
    property of the abutting landowner, but rather is a pub-
    lic sidewalk.’’ The court additionally noted Cyr’s deter-
    mination that the ‘‘area within the red circle on the
    photograph is owned and maintained by the city of
    Hartford, not the abutting landowner.’’ On the basis of
    the request for admission and Cyr’s affidavit, the court
    determined that the defendants had sustained their bur-
    den of demonstrating that ‘‘there is no genuine issue
    of material fact that the plaintiff’s alleged fall occurred
    in the red-circled area of the request for admission, and
    that area is not owned and maintained by the defen-
    dants.’’
    Having concluded that the defendants met their initial
    burden, the court turned to whether the plaintiff had
    presented evidence establishing the existence of a dis-
    puted factual issue. The court first considered the plain-
    tiff’s affidavit, which it found flawed in two ways. First,
    the court found that ‘‘the plaintiff’s affidavit is self-
    serving as it is made by a party to the action’’ and,
    therefore, was insufficient to create a genuine issue of
    material fact. Second, the court stated that the plaintiff’s
    averment that his fall ‘‘occurred on the walkway main-
    tained and controlled by [the] defendants and/or their
    agents, and that their negligence caused the hazardous
    condition,’’ amounted to a conclusory statement that
    lacked evidentiary support.
    Next, the court turned to the exhibits submitted by
    the plaintiff. Specifically, the court considered the 2001
    demolition plan, the 2018 renovation and repair plan,
    and the sidewalk citation and correction records.9 The
    court assumed, without deciding, that the exhibits sub-
    mitted together with the plaintiff’s surreply were ‘‘suffi-
    cient to consider in support of the plaintiff’s objection,’’
    but found that such evidence failed to ‘‘establish a genu-
    ine issue of material fact regarding the location of the
    plaintiff’s fall, and who owns or controls the area where
    the plaintiff fell.’’ The court viewed the exhibits in light
    of the plaintiff’s arguments that the 2001 demolition
    plan showed that the defendants constructed the walk-
    way and abutting sidewalk and that the 2018 renovation
    and repair plan showed plans to correct the slope of
    the walkway meeting the abutting sidewalk. The court
    found that the plaintiff’s arguments were flawed
    ‘‘because these defects, modifications, and/or correc-
    tions are not apparently clear from the face of the plans,
    and there is no affidavit from an individual with per-
    sonal knowledge of the area that can attest to what the
    plaintiff argues is contained with the plans. Without
    more, these are merely the plaintiff’s own interpreta-
    tions and assertions of the 2001 and 2018 plans and
    cannot create any genuine issue of material fact regard-
    ing the plaintiff’s fall.’’
    With respect to the sidewalk citation and correction
    records, the court stated that the records showed that
    the owner defendants were issued citations related to
    other addresses along Park Terrace, but that the record
    provided by the plaintiff lacked any reference to the
    property at issue, 286 and 290 Park Terrace. Thus, the
    court determined that such evidence ‘‘[did] not create
    a genuine issue of fact as to whether there was a defect,
    or whether the defendants were responsible for keeping
    the abutting sidewalk at 286 and 290 Park Terrace in
    a safe condition.’’ Having reviewed the evidence submit-
    ted by the plaintiff, the court determined that there was
    no genuine issue of material fact.
    The court next set forth the general rule that abutting
    landowners generally are not liable for injuries sus-
    tained on a defective public sidewalk. The court then
    addressed the plaintiff’s argument that the exception
    to the general rule, in situations in which the defect in
    the sidewalk was caused by an affirmative or positive
    act of the landowner, applied.10 Specifically, the plaintiff
    had argued ‘‘that the defendants constructed both the
    walkway and abutting sidewalk in 2001 and that the
    defendant ha[d] maintained, repaired, and renovated
    both the walkway and the abutting sidewalk.’’ The court
    rejected this argument on the basis that the plaintiff
    failed to allege in his complaint that the defendants
    constructed the walkway or abutting sidewalk.
    Accordingly, the court rendered judgment in favor of
    the defendants. This appeal followed. Additional facts
    and procedural history will be provided as necessary.
    I
    With respect to the trial court’s decision granting the
    defendant’s motion for summary judgment, the plaintiff
    claims that the court improperly determined that no
    genuine issues of material fact existed. Specifically, the
    plaintiff contends that there are genuine issues of mate-
    rial fact with respect to the scope and extent of the
    physical characteristics and location of the hazardous
    condition; whether the abutting sidewalk was a munici-
    pal sidewalk, whose obligation it was to maintain the
    sidewalk, and who was in possession and control over
    the location of the plaintiff’s fall;11 and whether the
    defendants engaged in positive acts. We disagree with
    the plaintiff.
    We first set forth the applicable standard of review
    and principles of law. ‘‘The standards governing our
    review of a trial court’s decision to grant a motion for
    summary judgment are well established. Practice Book
    [§ 17-49] provides that summary judgment shall be ren-
    dered forthwith if the pleadings, affidavits and any other
    proof submitted show that there is no genuine issue as
    to any material fact and that the moving party is entitled
    to judgment as a matter of law. . . . In deciding a
    motion for summary judgment, the trial court must view
    the evidence in the light most favorable to the nonmov-
    ing party. . . . The party seeking summary judgment
    has the burden of showing the absence of any genuine
    issue [of] material facts which, under applicable princi-
    ples of substantive law, entitle him to a judgment as a
    matter of law . . . and the party opposing such a
    motion must provide an evidentiary foundation to dem-
    onstrate the existence of a genuine issue of material
    fact. . . . A material fact . . . [is] a fact which will
    make a difference in the result of the case. . . . When
    . . . the trial court draws conclusions of law, our
    review is plenary and we must decide whether its con-
    clusions are legally and logically correct and find sup-
    port in the facts that appear in the record.’’ (Citation

    found to exist does the trier of fact then determine
    whether the defendant violated that duty in the particu-
    lar situation at hand. . . . Because the court’s determi-
    nation of whether the defendant owed a duty of care
    to the plaintiff is a question of law, our standard of
    review is plenary.’’ (Citation omitted; internal quotation

    A
    The plaintiff first contends that there existed genuine
    issues of material fact as to the extent and location of
    the defective condition causing his alleged fall. Specifi-
    cally, he argues that ‘‘the hazardous condition was not
    just the lip causing the fall, but the steep slope of the
    entire walkway that contributed to the defective raised
    lip on the slab.’’ The plaintiff points to the allegations
    of his complaint that his injuries were caused by the
    defendants’ failure ‘‘to lower the walkway so that it
    was level with the abutting sidewalks.’’ The plaintiff
    contends that the court ignored his allegations and sup-
    porting evidence, including photographs that depicted
    the steep slope and documentary evidence suggesting
    that the defendants constructed the walkway. The plain-
    tiff argues in the alternative that, even if the entire
    walkway does not constitute the hazardous condition,
    the ‘‘concrete slab with the raised lip . . . is the hazard-
    ous condition.’’ The plaintiff contends that he submitted
    evidence that the slab extends onto the owner defen-
    dants’ property and, thus, there exist genuine issues of
    material fact as to whether the slab is the hazardous
    condition, the length of the slab, and whether it extends
    onto the owner defendants’ property. The design defen-
    dants maintain that the location of the plaintiff’s
    claimed fall was conclusively established by the request
    for admission and the owner defendants further
    respond that the plaintiff’s arguments as to the slab and
    entire walkway are therefore irrelevant. We agree with
    the defendants.
    As noted previously, the owner defendants served
    the plaintiff with a request for admission that included
    an attached photograph and requested that the plaintiff
    admit, inter alia, that the area encircled in red in that
    photograph ‘‘fairly and accurately depicts . . . the
    alleged proximately causative defect of the claimed fall
    as asserted in the complaint . . . .’’ The plaintiff did
    not respond to the request. Pursuant to Practice Book
    § 13-23 (a), the plaintiff’s failure to respond to the
    request for admission resulted in his admission of the
    matter contained therein. See Bank of America, N.A.
    v. Kydes, 
    183 Conn. App. 479
    , 488, 
    193 A.3d 110
     (‘‘[t]he
    defendant’s failure to timely answer or object to the
    requests for admission pursuant to § 13-23 (a), and his
    subsequent failure to ask the court for permission to
    withdraw or amend those admissions pursuant to [Prac-
    tice Book] § 13-24 (a), resulted in his admission of all
    the matters as to which admissions were requested’’),
    cert. denied, 
    330 Conn. 925
    , 
    194 A.3d 291
     (2018). Specifi-
    cally, it was admitted that the area encircled in red in
    the photograph attached to the request for admission
    depicted the alleged defect that proximately caused the
    plaintiff’s claimed fall. At no time did the plaintiff seek
    permission to withdraw or amend the admission, and
    the trial court appropriately recognized in its memoran-
    dum of decision that ‘‘it has been conclusively estab-
    lished that the photo[graph] . . . fairly and accurately
    depicts the location of the plaintiff’s fall and the alleged
    defect is contained with the red encircled area of the
    photograph.’’
    The plaintiff contends in his reply brief that the defec-
    tive condition was not established by the request for
    admission. He maintains that the admission established,
    at most, the location of the fall, not the defective condi-
    tion that caused the fall. We reject the plaintiff’s attempt
    to minimize the effect of his admission and conclude
    that the court properly relied on the admission as con-
    clusively establishing that the alleged defect is con-
    tained within the red encircled area of the photograph,
    which does not encompass the whole slab or the entire
    walkway.12 Accordingly, the court properly concluded
    that there were no genuine issues of material fact with
    respect to the extent and location of the defective condi-
    tion causing the plaintiff’s alleged fall.
    B
    The plaintiff next contends that the evidence that he
    submitted ‘‘unequivocally created an issue of material
    fact as to whether the abutting sidewalk was a munici-
    pal sidewalk or was owned by the abutting owners
    . . . . Moreover, the evidence similarly created an
    issue regarding whose responsibility it was to maintain
    the abutting sidewalk.’’ In support of this argument, the
    plaintiff relies on various sidewalk citations, which he
    contends ‘‘shows that both the city, along with [the
    owner defendants], determined that the legal obligation
    to maintain the abutting sidewalk belonged to [the
    owner defendants].’’ He also points to the 2001 demoli-
    tion plan as showing that the owner defendants ‘‘con-
    structed the abutting sidewalk,’’ and the 2018 renova-
    tion and repair plan as showing that the design
    defendants negligently designed the walkway. The
    owner defendants respond that, because the sidewalk
    citations do not relate to the property at issue, the
    citations are irrelevant and do not create a genuine
    issue of material fact. They further respond that the
    2001 demolition plan and 2018 renovation and repair
    plan are ‘‘unclear’’ and ‘‘not self-evident’’ and the trial
    court properly determined that these documents did
    not create a genuine issue of material fact.13 We agree
    with the owner defendants.
    The owner defendants submitted with their motion
    for summary judgment Cyr’s affidavit, in which he
    averred that the ‘‘area within the red circle on that
    photograph, Exhibit A, is not private property of the
    abutting owner; rather, it is very clearly public sidewalk
    based on the Survey Map. The area encircled in red on
    Exhibit A is within the public right-of-way. . . . That
    area within the red circle on the photograph, is owned
    and maintained by the [c]ity of Hartford, and not by
    the abutting landowner.’’ (Emphasis omitted.) The trial
    court determined, and we agree, that this evidence,
    together with the plaintiff’s admission as to the location
    and proximate cause of his claimed fall, submitted by
    the owner defendants satisfied their initial burden, as
    the movants for summary judgment, to establish the
    nonexistence of a genuine issue of material fact as to
    ownership and maintenance of the sidewalk.
    The burden then shifted to the plaintiff, as the non-
    moving party, to demonstrate the existence of some
    disputed factual issue. Fiano v. Old Saybrook Fire Co.
    No. 1, Inc., 
    332 Conn. 93
    , 101, 
    209 A.3d 629
     (2019)
    (‘‘[o]nce the moving party has met its burden . . . the
    opposing party must present evidence that demon-
    strates the existence of some disputed factual issue’’).
    The plaintiff attempted to satisfy his burden by submit-
    ting the sidewalk citation and correction records, the
    2001 demolition plan, and the 2018 renovation and
    repair plan. As the trial court recognized, the sidewalk
    citation and correction records relate to other proper-
    ties on Park Terrace, but do not involve the property
    at issue. We agree with the trial court that ‘‘[w]hether
    the defendants were issued citations for other proper-
    ties along Park Terrace does not create a genuine issue
    of fact as to whether . . . the defendants were respon-
    sible for keeping the abutting sidewalk at 286 and 290
    Park Terrace in a safe condition.’’14
    With respect to the 2001 demolition plan, the plaintiff
    argues that ‘‘[o]nly a cursory review without any techni-
    cal expertise reveals [that] the walkway and abutting
    sidewalk were constructed by [the owner defendants].’’
    He represents that on page one of the 2001 demolition
    plan, the walkway is not present, but that on page C-
    1 of the demolition plan, the walkway area ‘‘shows dots’’
    and there are also ‘‘dotted areas’’ ‘‘denoting demolished
    or removed.’’ He represents that page two of the 2001
    demolition plan shows that the walkway was installed
    after the demolition. He concludes: ‘‘[A] cross-reference
    on page one (demolition and removal work) and page
    two (new work) shows [that the owner defendants]
    demolished the previous driveway areas and installed
    the walkways between each building.’’
    Additionally, the plaintiff argues that the 2001 demoli-
    tion plan shows that the owner defendants also con-
    structed the abutting sidewalk. He argues: ‘‘The 2001
    demolition plan also shows [that the owner defendants]
    constructed the abutting sidewalk. A review of page
    one of the 2001 demolition plan clearly shows the dots
    across the abutting sidewalk which denotes demolished
    and removed, as with the walkways. . . . This is high-
    lighted. . . . Moreover, the abutting sidewalk is
    denoted ‘All Conc. Walks and Aprons to be Demolished
    and Removed (As Shown, Typical).’ . . . This is also
    highlighted. . . . This shows the abutting sidewalk,
    including aprons, were removed. . . .
    ‘‘Page two of the demolition plan also clearly shows
    that a new abutting sidewalk with aprons was con-
    structed as part of the new work. Indeed, the plans
    denote ‘4’’ conc. Walk’, the plans for the thickness of
    the concrete of the abutting sidewalk. . . . This also
    is highlighted. . . . Page two of the 2001 demolition
    plans also denoted new curbing on the abutting side-
    walk and new aprons, also highlighted. . . . On page
    two, the New Child Safe Surfacing is also denoted on
    the abutting sidewalk. . . . [The owner defendants]
    therefore also constructed the entire abutting side-
    walk.’’ (Citations omitted; emphasis omitted.)
    We first note that the plaintiff’s argument in his appel-
    late brief cites and refers to uncertified reproductions
    of portions of the 2001 demolition plan contained in
    the appendix to his appellate brief. Further, these uncer-
    tified reproductions contain highlighting and handwrit-
    ten notations.15 In its memorandum of decision, the trial
    court stated that all of its references were to the exhibits
    contained in docket entry number 150.00. None of those
    exhibits contain highlighting or handwritten notations.
    Like the trial court, we consider the exhibits contained
    in docket entry number 150.00 for purposes of determin-
    ing whether the plaintiff satisfied his burden of demon-
    strating a genuine issue of material fact and we do not
    consider the highlighted documents or the plaintiff’s
    arguments premised thereon.
    Having thoroughly examined the 2001 demolition
    plan, we agree with the trial court that it does not
    demonstrate a genuine issue of material fact. First,
    much of the document contains print so small and
    blurry as to be practically unreadable. Aside from the
    readability failure, the greater concern is what can be
    demonstrated by the document alone. First, the text,
    some of which is merely abbreviations, fails to explicate
    these technical design plans. The plaintiff’s counsel
    points to dotted areas supposedly depicting demolition
    and other text on the plan purportedly indicating con-
    struction. However, the representations of the plaintiff’s
    counsel as to what is depicted in and the significance
    of the text on the 2001 demolition plan are not evidence.
    See Hudson City Savings Bank v. Hellman, 
    196 Conn. App. 836
    , 863, 
    231 A.3d 182
     (2020) (representations of
    counsel that barcode and numbers on envelope consti-
    tuted evidence that envelope was sent by regular mail
    were not evidence); see also Brusby v. Metropolitan
    District, 
    160 Conn. App. 638
    , 652 n.12, 
    127 A.3d 257
    (2015) (‘‘[t]his court, as well as our Supreme Court,
    repeatedly has stated that representations of counsel
    are not evidence’’ (internal quotation marks omitted)).
    The owner defendants’16 motion for summary judg-
    ment was supported by an expert affidavit, but the
    plaintiff did not provide any expert opinion in response
    to the averments of the owner defendants’ expert to
    establish any genuine issue of material fact. See Kout-
    soukos v. Toyota Motor Sales, U.S.A., Inc., 
    137 Conn. App. 655
    , 662–64, 
    49 A.3d 302
     (where defendants’ expert
    averred that airbag responded properly to accident,
    summary judgment was appropriate because plaintiff
    failed to offer expert opinion demonstrating airbag was
    defective), cert. denied, 
    307 Conn. 933
    , 
    56 A.3d 714
    (2012). Nor did the plaintiff support his opposition to
    summary judgment with affidavits17 or deposition testi-
    mony of fact witnesses with personal knowledge of
    the plans or the property. See Salamone v. Wesleyan
    University, 
    210 Conn. App. 435
    , 443, 
    270 A.3d 172
     (2022)
    (‘‘It is not enough . . . for the opposing party merely
    to assert the existence of such a disputed issue. Mere
    assertions of fact . . . are insufficient to establish the
    existence of a material fact and, therefore, cannot refute
    evidence properly presented to the court. . . . [T]ypi-
    cally [d]emonstrating a genuine issue requires a show-
    ing of evidentiary facts or substantial evidence outside
    the pleadings from which material facts alleged in the
    pleadings can be warrantably inferred.’’ (Internal quota-
    tion marks omitted.)). The trial court determined, and
    we agree, that the ‘‘defects, modifications, and/or cor-
    rections’’ as argued by the plaintiff, are ‘‘not apparently
    clear from the face of the plans.’’ Without some aid,
    either in the form of expert opinion or a witness with
    personal knowledge, to explain the 2001 demolition
    plan, it is insufficient to demonstrate a genuine issue
    of material fact.
    The 2018 renovation and repair plan, which is con-
    tained in docket entry number 150.00 as exhibits B and
    E, likewise does not create a genuine issue of material
    fact. First, the portion of the plan labeled ‘‘Exhibit B’’
    is dated April 25, 2018, and the portion of the plan
    labeled ‘‘Exhibit E’’ is dated June 20, 2018—both dates
    are subsequent to the date of the plaintiff’s alleged fall.
    Second, the 2018 renovation and repair plan suffers
    from the same defects as the 2001 demolition plan.
    Although the document titles are legible, none of the
    extensive textual notes or legends on the documents
    are legible. Like the 2001 demolition plan, the 2018
    renovation and repair plan is unaccompanied by any
    affidavit to aid in its utility or interpretation.
    The plaintiff contends that ‘‘our courts have held that
    maps and surveys alone are sufficient to create an issue
    of material fact without any affidavit of a surveyor or an
    individual with personal knowledge of such surveys.’’18
    The Superior Court decisions cited by the plaintiff,
    which are not binding precedent on this court, are also
    factually distinguishable. In Marone v. Coric, Superior
    Court, judicial district of New London, Docket No. CV-
    XX-XXXXXXX (February 18, 2011), the court recognized,
    without the submission of an affidavit, that a survey of
    a piece of property showed that the property contained
    17.65 acres rather than 21 acres. See also Dufford v.
    Jones-Richards, Inc., Superior Court, judicial district of
    Hartford, Docket No. CV-XX-XXXXXXX (January 8, 2009)
    (survey showed acreage of property was 6.4 acres more
    or less); Danbury v. Novella, Superior Court, judicial
    district of Danbury, Docket No. 318827 (April 17, 1996)
    (noting that land was designated as open space on tax
    maps). The information needed to be gleaned from the
    documents in the Superior Court decisions cited by the
    plaintiff is significantly less complex than the informa-
    tion the plaintiff seeks the court to extract and utilize
    from the exhibits he has filed. Moreover, there is no
    indication in those cases that there were any readability
    concerns with the documents.
    Accordingly, we agree with the trial court that the
    plaintiff failed to present evidence demonstrating a gen-
    uine issue of material fact as to the ownership or mainte-
    nance of the area in which he allegedly fell.
    C
    The plaintiff’s next contention is that there exists a
    genuine issue of material fact as to whether the owner
    defendants and the design defendants engaged in posi-
    tive acts involving the area in which the plaintiff fell.
    Specifically, relying on the 2001 demolition plan, the
    plaintiff contends that the owner defendants con-
    structed the walkway and abutting sidewalk and, rely-
    ing on the 2018 renovation and repair plan, argues that
    the owner defendants contracted with the design defen-
    dants to design substantial repairs and renovations to
    the property, including the walkway and abutting side-
    walk. The defendants respond that the operative com-
    plaint does not allege any positive acts. We agree with
    the defendants.
    As noted previously, the general rule is that ‘‘an abut-
    ting landowner is not liable for injuries sustained by a
    traveler on the highway that were caused by the defec-
    tive condition of a public sidewalk. . . . There are two
    exceptions to the general rule: (1) where a statute or
    ordinance shifts liability to the landowner to keep the
    sidewalk in a safe condition . . . and (2) where the
    affirmative or positive act of the landowner causes the
    defect in the sidewalk.’’ (Citations omitted.) Pollard v.
    Bridgeport, supra, 
    204 Conn. App. 198
    . In order to fall
    within the second exception, the plaintiff was required
    to assert allegations that the defendants caused the
    defect by performing a positive act. See Cyr v. VKB,
    LLC, 
    194 Conn. App. 871
    , 880, 
    222 A.3d 965
     (2019); see
    also McFarline v. Mickens, 
    supra,
     
    177 Conn. App. 86
    –88
    (where plaintiff alleged that she tripped and fell because
    of defect consisting of ‘‘a broken and cracked concrete
    sidewalk and adjacent curb with grass growing wildly
    through the crack and broken sections,’’ court properly
    rendered summary judgment in absence of any allega-
    tions in complaint that defendant created wildly grow-
    ing grass through positive act (internal quotation marks

    194 Conn. App. 871
    , guides our analysis. In that case, the
    plaintiff had alleged that while walking on a public
    sidewalk, she tripped on ‘‘an approximately one and
    one-half inch lip between two sidewalk segments’’ and
    fell, sustaining injuries. Id., 874. The plaintiff com-
    menced an action against five defendants, including the
    owners of the property abutting the sidewalk, alleging
    negligence, among other causes of action. Id., 874–75.
    The plaintiff asserted alternative theories as to the cre-
    ation of the alleged defect. Id. In counts four and five
    of her complaint, the plaintiff alleged that the claimed
    defect ‘‘developed as a result of the settling of one
    adjacent segment.’’ (Internal quotation marks omitted.)
    Id. In counts three, six, and seven of her complaint, the
    plaintiff alleged that certain defendants had ‘‘con-
    structed a sidewalk on the property with a resulting
    approximately 1 1/2’’ lip between the sidewalk segments
    it installed and the sidewalk on the adjoining property.’’
    (Internal quotation marks omitted.) Id., 881. The defen-
    dants filed a motion for summary judgment in which
    they argued that there was no evidence ‘‘that the defen-
    dants created the alleged defect so as to fall within an
    exception to the general rule that liability remains with
    the municipality in cases involving public sidewalk
    defects.’’ Id., 875–76. The court granted the motion for
    summary judgment. Id., 876.
    On appeal, this court first considered the counts in
    which the plaintiff had alleged settling of the sidewalk
    and determined that those counts lacked any allegation
    that a ‘‘positive act on the part of the defendants caused
    the settling of the sidewalk segment.’’ Id., 882. This
    court explained that ‘‘the allegation that the defect in
    the sidewalk ‘developed as a result of the settling of
    one adjacent segment’ suggests only that the alleged
    settling resulted from nature and the passage of time,
    which is insufficient as a matter of law to impose a
    duty on an abutting landowner.’’ Id. Thus, this court
    concluded that those counts were legally insufficient
    and the trial court properly had rendered summary judg-
    ment thereon. Id.
    This court next examined the counts in which the
    plaintiff had alleged that the defendants ‘‘constructed
    a sidewalk on the property with a resulting approxi-
    mately 1 1/2’’ lip between the sidewalk segments it
    installed and the sidewalk on the adjoining property.’’
    (Internal quotation marks omitted.) Id., 883. This court
    determined that this allegation ‘‘may be reasonably
    viewed as alleging that [the defendants] constructed
    the sidewalk with the alleged defect (i.e., that the
    alleged defect resulted from the construction of the
    sidewalk).’’ Id., 884. Because the plaintiff had alleged
    that the defendants constructed the sidewalk, the defen-
    dants, in order to prevail on their motion for summary
    judgment, were required ‘‘to proffer evidence that either
    they did not construct the sidewalk or that they con-
    structed the sidewalk without the alleged defect.’’ Id.,
    885. The defendants submitted evidentiary materials
    with their reply brief, and the plaintiff did not object
    to the court’s consideration of those materials. Id., 886
    n.5. This court concluded that the materials submitted
    by the defendants did not establish the nonexistence of
    a genuine issue of material fact, because such materials
    lacked ‘‘any affidavits or other supporting documents
    that demonstrate that the defendants either did not
    construct the sidewalk or constructed the sidewalk
    without the alleged defect.’’19 Id., 885–86.
    In the present case, the plaintiff did not allege in his
    operative complaint that the owner defendants or the
    design defendants constructed the walkway or abutting
    sidewalk nor did he allege that they undertook any other
    positive act with respect to the walkway or abutting
    sidewalk. Instead, he alleged that the defendants failed
    to take affirmative steps to remediate the defective
    condition. For example, the plaintiff alleged that the
    defendants ‘‘failed to lower the walkway’’ and ‘‘failed
    to shave down the slab of the walkway so it was not
    higher than the abutting sidewalks.’’ The only allegation
    approaching a positive act is his allegation that the
    defendants ‘‘failed to position the slab of the walkway
    so that it was level with the abutting sidewalks.’’20 The
    allegation that there exists a walkway that is raised
    higher than the abutting sidewalk cannot be construed
    as alleging that the defendants, through a positive act,
    caused the defect in the sidewalk.21 With respect to the
    design defendants, the plaintiff also alleged only the
    failure to take affirmative steps with respect to the
    design, inspection, and remedy of the alleged defect.
    Like his claims against the owner defendants, the plain-
    tiff’s claims against the design defendants fail to allege
    positive acts.22 Therefore, the plaintiff’s claims do not
    fall within the positive act exception to the common-
    law rule that an abutting landowner is under no duty to
    keep the public sidewalk in front of its property safe.23
    II
    The plaintiff’s second claim on appeal is that the court
    improperly denied his request to amend his revised
    complaint. We disagree.
    The following additional procedural history is rele-
    vant to this claim. As noted previously, on July 7, 2021,
    the parties appeared before the court for oral argument
    on the defendants’ motions for summary judgment,
    which had been briefed fully by all parties. The plain-
    tiff’s counsel, at the commencement of the scheduled
    argument, orally requested a two week continuance of
    the oral argument and also requested permission to
    file a surreply, which requests the court granted. The
    plaintiff’s counsel did not alert the court at that time
    that he intended to file a request to amend his complaint.
    Two weeks later, on July 21, 2021, the plaintiff filed his
    surreply briefs and also filed a request to amend his
    complaint and memorandum in support of that request.
    In his request, he represented that he sought to include
    allegations that the owner defendants constructed the
    walkway and abutting sidewalk, that the owner defen-
    dants repaired and maintained the walkway and abut-
    ting sidewalk, that the design defendants ‘‘designed,
    oversaw and participated in a substantial renovation of
    the property [in] 2018 which included the walkway and
    abutting sidewalk,’’ and that the design defendants ‘‘pro-
    vided the plaintiff certain surveys while the plaintiff
    was employed by a subcontractor of the defendants,
    which the plaintiff relied on during the scope of his
    employment, and such surveys failed to adequately
    warn him of the hazardous condition on the property
    which caused his injuries.’’ The defendants objected to
    the request to amend the complaint, and the plaintiff
    filed a reply. The owner defendants subsequently filed
    a surreply.
    On October 13, 2021, the court denied the plaintiff’s
    request to amend his complaint. In its order, the court
    found that ‘‘there would clearly be great prejudice to
    the defendants if the plaintiff was permitted to amend
    the complaint to allege new theories of liability against
    the defendants following both the filing and oral argu-
    ment of the pending motions for summary judgment.
    The undue delay is obvious since even a cursory review
    of the requested revisions shows new theories of liabil-
    ity alleged against the defendants. Such new theories
    would necessitate discovery and resultant delay in con-
    cluding this matter either by summary judgment or ulti-
    mately at trial.’’ The court concluded, given the history
    of the case, that it would be unjust to permit the plaintiff
    to further delay the matter. Accordingly, it denied the
    request to amend.
    On appeal, the plaintiff argues that the court abused
    its discretion in denying his request to amend because
    he ‘‘did not assert new counts of liability, only allega-
    tions that conform to the original allegations of posses-
    sion and control over the area where [he] fell.’’ He
    contends that the delay was not unreasonable, in that
    he was unable to obtain the documents from the city
    ‘‘due to the limited access to town hall in 2020 during
    [the] pandemic.’’
    We first set forth our standard of review. ‘‘Our stan-
    dard of review of the [plaintiff’s] claim is well defined.
    A trial court’s ruling on a motion of a party to amend
    its complaint will be disturbed only on the showing of
    a clear abuse of discretion. . . . Whether to allow an
    amendment is a matter left to the sound discretion of
    the trial court. [An appellate] court will not disturb a
    trial court’s ruling on a proposed amendment unless
    there has been a clear abuse of that discretion. . . . It
    is the [plaintiff’s] burden in this case to demonstrate
    that the trial court clearly abused its discretion. . . .
    ‘‘A trial court may allow, in its discretion, an amend-
    ment to pleadings before, during, or after trial to con-
    form to the proof. . . . Factors to be considered in
    passing on a motion to amend are the length of the
    delay, fairness to the opposing parties and the negli-
    gence, if any, of the party offering the amendment. . . .
    The essential tests are whether the ruling of the court
    will work an injustice to either the plaintiff or the defen-
    dant and whether the granting of the motion will unduly
    delay a trial.’’ (Internal quotation marks omitted.)

    336 Conn. 909

    244 A.3d 562
     (2021). ‘‘The trial court is in the best
    position to assess the burden which an amendment
    would impose on the opposing party in light of the
    facts of the particular case.’’ (Internal quotation marks
    omitted.) Mastrolillo v. Danbury, 
    61 Conn. App. 693
    ,
    696, 
    767 A.2d 1232
     (2001).
    The plaintiff has failed to demonstrate that the court
    abused its discretion in disallowing the amendment.24
    When the plaintiff filed his request to amend after the
    scheduled date of oral argument, the defendants’
    motions for summary judgment had been briefed. The
    trial court found that permitting the amendment would
    prejudice the defendants in that it would alter the sub-
    stance of the plaintiff’s claim while the motions for
    summary judgment were pending. The court deter-
    mined that the new theories of liability would require
    additional discovery and occasion further delay. In light
    of the delay and likelihood that the amendment would
    prejudice the defendants, we conclude that the court’s
    ruling did not reflect an abuse of its discretion.
    III
    In one paragraph of his principal appellate brief, the
    plaintiff claims that the court abused its discretion in
    denying his motion to preclude the expert witness affi-
    davit offered by the owner defendants in support of
    their motion for summary judgment. We conclude that
    the plaintiff’s claim is inadequately briefed.
    ‘‘We repeatedly have stated that [w]e are not required
    to review issues that have been improperly presented
    to this court through an inadequate brief. . . . Analy-
    sis, rather than mere abstract assertion, is required in
    order to avoid abandoning an issue by failure to brief
    the issue properly. . . . [When] a claim is asserted in
    the statement of issues but thereafter receives only
    cursory attention in the brief without substantive dis-
    cussion or citation of authorities, it is deemed to be
    abandoned. . . . For a reviewing court to judiciously
    and efficiently . . . consider claims of error raised on
    appeal . . . the parties must clearly and fully set forth
    their arguments in their briefs.’’ (Citation omitted; inter-
    nal quotation marks omitted.) Burton v. Dept. of Envi-
    ronmental Protection, 
    337 Conn. 781
    , 803, 
    256 A.3d 655
     (2021).
    The plaintiff devotes only one paragraph of his princi-
    pal brief to this claim. ‘‘Although the number of pages
    devoted to an argument in a brief is not necessarily
    determinative, relative sparsity weighs in favor of con-
    cluding that the argument has been inadequately
    briefed.’’ (Internal quotation marks omitted.) Id., 805.
    The plaintiff states that ‘‘[t]he trial court erroneously
    denied [the plaintiff’s] motion to preclude because [the
    Cyr survey] contained numerous errors raising serious
    issues of credibility. . . . The discrepancies are dis-
    cussed in detail in [the plaintiff’s] motion to preclude.’’
    The plaintiff has provided no analysis in support of
    this argument. To the extent that the plaintiff seeks to
    incorporate by reference any arguments raised in his
    motion to preclude, these arguments are inadequately
    briefed.25 See Cambridge Mutual Fire Ins. Co. v. Sakon,
    
    132 Conn. App. 370
    , 383 n.6, 
    31 A.3d 849
     (2011) (argu-
    ments from opposition to motion for summary judg-
    ment incorporated by reference into appellate brief are
    deemed inadequately briefed), cert. denied, 
    304 Conn. 904
    , 
    38 A.3d 1202
     (2012). Accordingly, we decline to
    review the plaintiff’s claim.
    The judgment is affirmed.
    In this opinion the other judges concurred.
    1
    On July 9, 2020, the design defendants filed requests to revise the plain-
    tiff’s original complaint. On November 1, 2020, the design defendants moved
    for entry of nonsuit against the plaintiff for failure to file a responsive
    pleading to their requests to revise, which motion for nonsuit was denied
    by the court after the plaintiff had filed the revised complaint.
    2
    The defendants filed answers including special defenses. The plaintiff
    filed a certificate of closed pleadings on February 22, 2021. Three days later,
    on February 25, 2021, the plaintiff, despite having filed a certificate of closed
    pleadings, filed replies to the defendants’ special defenses.
    3
    On October 20, 2020, the owner defendants served the plaintiff with a
    first request for admission, in which they incorrectly represented that the
    photograph marked as exhibit A was dated June 24, 2018. On November
    17, 2020, the plaintiff objected to the first request for admission on the basis
    that ‘‘the dates are different.’’ Thereafter, the owner defendants served the
    relevant request for admission.
    4
    Practice Book § 13-23 provides in relevant part: ‘‘(a) Each matter of
    which an admission is requested is admitted unless, within thirty days after
    the filing of the notice required by Section 13-22 (b), or within such shorter
    or longer time as the judicial authority may allow, the party to whom the
    request is directed files and serves upon the party requesting the admission
    a written answer or objection addressed to the matter, signed by the party
    or by his attorney. . . .’’
    5
    On May 21, 2021, the deadline contained in the scheduling order for
    filing his response to the motions for summary judgment, the plaintiff filed
    a motion for extension of time. Over the defendants’ objections, the court
    granted the plaintiff an extension until July 2, 2021. Oral argument on the
    motions originally was scheduled for June 29, 2021, but was continued, to
    allow time for the objections, until July 7, 2021, leaving the defendants one
    business day to file their reply briefs.
    6
    The plaintiff averred: ‘‘When I tripped and fell, I was an invitee for testing
    and data collection purposes for my employer Home Energy Technologies
    (HERS Rating firm), which was contracted by the [d]efendants (Crosskey
    and Mutual Housing Association of Greater Hartford) for rating and certifica-
    tion services of the [fourteen] buildings that are known as the Park Terrace
    II development . . . . I relied on building plans drafted by [the] defendant
    Crosskey . . . and site surveys drafted by [the] defendant TO Design to
    verify, test and inspect various stages of the renovation and repair process
    of the [fourteen] properties. I was not warned by the [d]efendants of the
    hazardous condition on the walkway.’’
    7
    In support of his request for a continuance, the plaintiff’s counsel repre-
    sented that the defendants’ reply briefs had been filed on the morning of
    the hearing and he would like the opportunity to file a surreply; he did not
    have the opportunity to review what the defendants had filed because he
    attended a funeral for a family member of a paralegal from his office and
    also experienced a death in his own family; and that his understanding was
    that the scheduled proceeding was for a status conference, not oral argument
    on the motions for summary judgment. Counsel for the owner defendants
    objected to the requested continuance, noting that he was prepared to argue
    the motion despite having been afforded only one business day to file his
    reply brief; see footnote 5 of this opinion; and that the plaintiff’s counsel
    had not contacted him about the continuance request. The court granted
    the requested continuance on the basis of the deaths experienced by the
    plaintiff’s counsel and granted his request for time to file a surreply.
    8
    All defendants objected to the request for leave to amend the complaint,
    the plaintiff filed a reply, and the court denied the request to amend. See
    part II of this opinion. On August 11, 2021, the plaintiff also filed a motion
    to preclude Cyr’s expert witness affidavit and memorandum of law in support
    thereof, which motion the court denied. See part III of this opinion.
    9
    The court also considered the unofficial property record cards for 286-
    288 Park Terrace and 290 Park Terrace, which the plaintiff submitted as
    exhibit D to his affidavit. The court noted that ‘‘[t]he plaintiff makes no
    arguments in any of his filings regarding how these property cards create
    a genuine issue of material fact.’’
    10
    The court noted that the plaintiff did not claim that the other exception
    to the general rule, where a statute or ordinance shifts liability to the land-
    owner, was applicable.
    11
    Although the plaintiff briefs possession and control separately, we dis-
    cuss the purported issues surrounding ownership, maintenance, and posses-
    sion and control together. See part I B of this opinion.
    12
    Last, we note that the plaintiff’s contention that it was the entire walk-
    way, or, in the alternative, the entire slab, that constituted the defect is
    unavailing for additional reasons, discussed further in part I B and C of this
    opinion. First, the plaintiff did not plead any allegations regarding a claimed
    ‘‘steep slope’’ of the walkway. Second, the plaintiff’s arguments relative to
    the slab are premised entirely on the documents submitted in support of
    his surreply to the defendant’s motion for summary judgment, which we
    determine are insufficient to demonstrate genuine issues of material fact.
    13
    The design defendants argue, inter alia, that neither the 2001 demolition
    plan nor the sidewalk citation and correction records create a genuine issue
    of material fact as to the design defendants. Specifically, they contend that
    the 2001 demolition plan was not prepared by the design defendants and
    note that the plaintiff does not allege that they were involved in or prepared
    the 2001 demolition plan. Similarly, with respect to the sidewalk citation
    and correction records, the design defendants argue that they do not create
    a genuine issue of material fact because the plaintiff has not alleged that
    they had any involvement with the property in the 1990s.
    14
    The plaintiff argues that ‘‘other courts have held that similar sidewalk
    citations, in itself, create an issue of material fact as to ownership and
    maintenance responsibilities.’’ The plaintiff cites only one unpublished case
    issued by the Appellate Division of the Superior Court of New Jersey, which
    involved the question of ‘‘whether a condominium association is obligated
    to indemnify a first-floor commercial unit owner in the building for sums
    that the commercial entity paid to settle claims brought by a pedestrian
    who tripped on an uneven portion of the adjacent public sidewalk.’’ Na v. 369
    First Street Condominium Assn., Superior Court of New Jersey, Appellate
    Division, Docket No. A-2971-14T3 (May 5, 2016). Although the court refer-
    enced a citation, issued following the pedestrian’s accident, to correct the
    sidewalk’s condition, the record also included evidence that the condomin-
    ium association, which was made up of the four units in a single building,
    had repaired the sidewalk and proportionately charged each of the unit
    owners for the costs. Id. We conclude that this factually and procedurally
    distinguishable case is not in any way persuasive of the plaintiff’s contention
    that the sidewalk citations in the current case demonstrate a genuine issue
    of material fact.
    15
    At oral argument before the trial court on the motions for summary
    judgment, the plaintiff’s counsel referred to certain of the highlighted docu-
    ments, which he previously had submitted in connection with his objections
    to the motions for summary judgment. When questioned by the court, the
    plaintiff’s counsel responded that ‘‘[m]y office’’ had highlighted the docu-
    ment.
    As noted previously, although the plaintiff argued, in his surreply, that
    his original submissions were sufficient to demonstrate a genuine issue
    of material fact, he also refiled, at docket entry number 150.00, certified
    documents. On appeal, he does not claim that the court erred in confining
    its consideration to the documents filed at docket entry number 150.00.
    16
    The plaintiff does not argue that the design defendants prepared the
    2001 demolition plan or had any involvement whatsoever in that plan. Thus,
    we analyze the 2001 demolition plan in relation to the owner defendants only.
    17
    Practice Book § 17-46 ‘‘sets forth three requirements necessary to permit
    the consideration of material contained in affidavits submitted in a summary
    judgment proceeding. The material must: (1) be based on personal knowl-
    edge; (2) constitute facts that would be admissible at trial; and (3) affirma-
    tively show that the affiant is competent to testify to the matters stated in
    the affidavit.’’ (Internal quotation marks omitted.) Atlantic St. Heritage
    Associates, LLC v. Atlantic Realty Co., 
    216 Conn. App. 530
    , 550, 
    285 A.3d 1128
     (2022).
    18
    The plaintiff raises three additional arguments in support of his con-
    tention that the exhibits he filed did not require accompanying affidavits.
    First, he argues that ‘‘allegations of a positive act that are not negated, as
    in Cyr [v. VKB, LLC, 
    194 Conn. App. 871
    , 880, 
    222 A.3d 965
     (2019)], are
    sufficient in itself to create an issue of material fact.’’ We address the premise
    of this contention in part I C of this opinion, wherein we conclude that the
    plaintiff failed to allege positive acts. Second, he argues that the exhibits
    he filed are ‘‘certified public documents, which are self-authenticated and
    exempt from the rules of hearsay.’’ The trial court, however, did not deter-
    mine that the documents were inadmissible on the basis that they had
    not been authenticated or contained hearsay. Rather, it assumed without
    deciding that the documents were admissible and afforded them consider-
    ation. Third, he argues that, even if an affidavit was required, his own
    affidavit satisfies the requirement, in that he attested to ‘‘where he obtained
    the plans and that he fell on the walkway owned and maintained by [the
    defendants].’’ With respect to his averment regarding ownership and mainte-
    nance of the walkway, the trial court determined, and we agree, that it
    constitutes a conclusory statement insufficient to demonstrate a genuine
    issue of material fact. ‘‘[A] nonmoving party’s conclusory affidavits alone
    are insufficient grounds to deny a motion for summary judgment.’’ Walker
    v. Housing Authority, 
    148 Conn. App. 591
    , 597, 
    85 A.3d 1230
     (2014).
    19
    The reply materials included ‘‘certificates of use and occupancy, two
    photographs of the sidewalk, excerpts from the plaintiff’s deposition tran-
    script, and the affidavit of Ronald J. Houde, Jr., Esq., attesting that the
    submitted documents are true and accurate copies.’’ Cyr v. VKB, LLC, supra,
    
    194 Conn. App. 886
     n.5.
    20
    The plaintiff cites Noel v. Beck, Superior Court, judicial district of Middle-
    sex, Docket No. CV-XX-XXXXXXX-S (August 16, 2013), in support of his con-
    tention that the allegation regarding a failure to position the slab level is
    sufficient to allege a positive act. In that case, the court denied the defen-
    dants’ motion to strike on the basis that the plaintiff sufficiently had alleged
    a positive act, where the plaintiff had defined ‘‘the alleged ‘positive act’ as
    the creating of ‘an abrupt change in the elevation from the sidewalk to the
    driveway resulting in a raised section of paving with an untreated vertical
    displacements,’ ’’ which act occurred while paving the driveway. 
    Id.
     In the
    present case, the plaintiff alleged a failure to lower the walkway, failure to
    shave down the slab, and failure to position the slab level, none of which
    rises to the level of the express allegations of paving the driveway and
    creating the raised section of paving.
    21
    Throughout his principal appellate brief, the plaintiff emphasizes the
    allegation contained in his complaint that the defendants ‘‘were in control
    of’’ the walkway. He contends that ‘‘allegations of possession and control
    are sufficient allegations of a positive action.’’ The decisions of the Superior
    Court cited by the plaintiff in support of this contention are distinguishable.
    In Schumacher v. Morey, Superior Court, judicial district of Ansonia-Milford,
    Docket No. CV-98064798 (August 10, 2001), the court denied a motion to
    strike where the plaintiff had alleged possession and control of a metal pipe
    that protruded from the sidewalk, not possession and control of the sidewalk
    generally. In Stahl v. Hadelman, Superior Court, judicial district of New
    Haven, Docket No. 411954 (May 17, 1999), the court denied the defendants’
    motion for summary judgment on the basis that the defendants had not
    rebutted the allegation, made in the complaint, that the defendants owned
    the sidewalk, that is, that the sidewalk was within the owner’s property
    line. Thus, contrary to the representation in the plaintiff’s appellate brief,
    the court in Stahl did not deny the motion for summary judgment on the
    basis that the allegations and evidence ‘‘[were] sufficient to establish positive
    acts . . . .’’
    22
    The plaintiff also contends that summary judgment should have been
    denied on the basis that he had alleged the defendants’ failure to warn him
    of the hazardous condition. In support of this argument, he contends that
    ‘‘our courts have held that a duty to warn exists to business invitees for
    hazards on an abutting sidewalk in the immediate vicinity of the property.’’
    The Superior Court decisions on which the plaintiff relies do not support
    his argument and are factually distinguishable. See Eaves v. Ebonas, LLC,
    Superior Court, judicial district of Hartford, Docket No. CV-XX-XXXXXXX-S
    (August 5, 2021) (denying motion for summary judgment where evidence
    demonstrated ‘‘competing inferences of material fact’’ including ownership
    of sidewalk); Swain v. Leninski, 
    47 Conn. Supp. 660
    , 665–66, 
    823 A.2d 462
    (2003) (granting defendant’s motion for summary judgment after concluding
    that defendant had no duty under Wilson v. New Haven, 
    supra,
     
    213 Conn. 277
    , to warn user of public sidewalk of defect, declining to address whether
    there exists exception to Wilson rule in cases where ‘‘dangerous defect
    exists immediately outside an exit’’ (emphasis added)).
    23
    Finally, the plaintiff argues that ‘‘the trial court failed to address [the
    plaintiff’s] argument that there is also an issue of material fact whether [the
    defendants] were in possession and control over the area where [the plaintiff]
    fell, which is an element of all premises liability actions. This is a separate and
    distinct analysis from the positive action doctrine, independently requiring
    denial of [the defendants’ motions for summary judgment].’’ We disagree
    that the trial court failed to address this contention. The trial court deter-
    mined that the defendants satisfied their burden of demonstrating that there
    was no genuine issue of material fact that the plaintiff’s alleged fall occurred
    on land owned and maintained by the city of Hartford and that the plaintiff
    failed to submit evidence to demonstrate a genuine issue of material fact
    as to whether the area in which his claimed fall occurred was owned or
    maintained by the defendants.
    24
    The plaintiff argues that our appellate courts ‘‘have unambiguously held
    that it is an abuse of discretion for a trial court to deny a motion to amend
    a complaint to conform to facts revealed during discovery that, if denied,
    would moot the moving party’s motion for summary judgment.’’ Contrary
    to the blanket rule suggested by the plaintiff, both cases on which he relies
    are fact specific and do not compel the conclusion that the court improperly
    denied the request to amend in the present case. See Falby v. Zarembski,
    
    221 Conn. 14
    , 25, 
    602 A.2d 1
     (1992) (court abused its discretion in denying
    plaintiffs’ motion to amend complaint where amendment sought to separate
    theories of liability that improperly had been pleaded in same count); Miller
    v. Fishman, 
    102 Conn. App. 286
    , 295, 
    925 A.2d 441
     (2007) (court abused its
    discretion in denying motion to amend where proposed amendment did not
    set forth new theories of liability and preparation of defense would not have
    required significant additional time and resources), cert. denied, 
    285 Conn. 905
    , 
    942 A.2d 414
     (2008).
    25
    The plaintiff also alludes vaguely to purported issues of credibility and
    errors in the Cyr survey in arguing that the court erroneously relied on Cyr’s
    affidavit in rendering summary judgment. For the same reasons previously
    set forth, we conclude that this argument is inadequately briefed.
