    U.S. Pipeline, Inc., appellee, v. Northern
    Natural Gas Company, appellant.
    ___ N.W.2d ___
    Filed June 28, 2019.    No. S-18-679.
    1. Trial: Witnesses: Evidence: Appeal and Error. In a bench trial of an
    action at law, the trial court is the sole judge of the credibility of the
    witnesses and the weight to be given their testimony; an appellate court
    will not reevaluate the credibility of witnesses or reweigh testimony but
    will review the evidence for clear error.
    2. Judgments: Appeal and Error. The trial court’s factual findings in a
    bench trial of an action at law have the effect of a jury verdict and will
    not be set aside unless clearly erroneous.
    3. ____: ____. In reviewing a judgment awarded in a bench trial of a law
    action, an appellate court considers the evidence in the light most favor-
    able to the successful party and resolves evidentiary conflicts in favor
    of the successful party, who is entitled to every reasonable inference
    deducible from the evidence.
    4. Judgments: Directed Verdict: Appeal and Error. In reviewing rul-
    ings on motions for directed verdict and judgments notwithstanding the
    verdict, an appellate court gives the nonmoving party the benefit of all
    evidence and reasonable inferences in his or her favor, and the question
    is whether a party is entitled to judgment as a matter of law.
    5. Contracts: Judgments: Appeal and Error. The meaning of a contract
    is a question of law, in connection with which an appellate court has an
    obligation to reach its conclusions independently of the determinations
    made by the court below.
    6. Damages: Appeal and Error. The amount of damages to be awarded is
    a determination solely for the fact finder, and its action in this respect
    will not be disturbed on appeal if it is supported by evidence and bears
    a reasonable relationship to elements of damages proved.
    7. Contracts: Damages: Appeal and Error. The issue of whether dam-
    ages are consequential under a contract is a question of law that an
    - 445 -

    appellate court reviews de novo, but the factual determinations underly-
    ing such a characterization are reviewed for clear error.
    8.   Expert Witnesses: Appeal and Error. The standard for reviewing the
    admissibility of expert testimony is abuse of discretion.
    9.   Contracts: Waiver: Damages. Generally, a contractual waiver or exclu-
    sion of consequential damages will be upheld unless the provision is
    unconscionable.
    10.   Contracts: Damages. Consequential damages, as opposed to direct
    damages, do not arise directly according to the usual course of things
    from a breach of contract itself.
    11.   ____: ____. Direct damages refer to those which the party lost from the
    contract itself—in other words, the benefit of the bargain—while conse-
    quential damages refer to economic harm beyond the immediate scope
    of the contract.
    12.   Trial: Evidence: Appeal and Error. Unless an objection to offered
    evidence is sufficiently specific to enlighten the trial court and enable it
    to pass upon the sufficiency of such objection and to observe the alleged
    harmful bearing of the evidence from the standpoint of the objector, no
    question can be presented therefrom on appeal.
    13.   Appeal and Error. An issue not properly presented and passed upon by
    the trial court may not be raised on appeal.
    14.   ____. In order to be considered by an appellate court, an alleged error
    must be both specifically assigned and specifically argued in the brief of
    the party asserting the error.
    15.   Waiver: Appeal and Error. Errors not assigned in an appellant’s
    initial brief are waived and may not be asserted for the first time in a
    reply brief.
    16.   Trial: Directed Verdict: Appeal and Error. In an appeal of a trial
    court’s refusal to enter a directed verdict, the appellate court should
    consider solely those grounds urged by the appellant to the trial court in
    support of its directed verdict motion.
    17.   ____: ____: ____. If a party fails to set forth certain arguments as
    grounds in a motion and renewed motion for directed verdict, such argu-
    ments will not be properly preserved for appeal.
    18.   Contracts: Waiver. The determination of whether a contractual provi-
    sion has been waived is a factual determination.
    19.   Contracts: Waiver: Damages. A contractual provision for liquidated
    damages for delay in performance may be waived.
    20.   Waiver: Estoppel. In order to establish a waiver of a legal right, there
    must be clear, unequivocal, and decisive action of a party showing such
    purpose, or acts amounting to estoppel on his or her part.

    21. Contracts: Waiver: Proof. A written contract may be waived in whole
    or in part, either directly or inferentially, and the waiver may be proved
    by express declarations manifesting the intent not to claim the advan-
    tage, or by so neglecting and failing to act as to induce the belief that it
    was the intention to waive.
    22. Contracts: Waiver. Even a provision in a written contract that specifies
    that a waiver of the conditions and terms of the agreement must be in
    writing may be waived by acts or conduct.

    I. NATURE OF CASE
    In 2014, a natural gas company solicited bids for a pipeline
    replacement and relocation project in northern Michigan. The
    natural gas company accepted a bid from a pipeline company,
    and the parties entered into a detailed construction contract.
    The contract provided that the project would be substantially
    completed by September 2014. However, because of extra
    work orders by the natural gas company and for various other
    reasons, the project was not substantially completed by that
    date. Based on a liquidated damages provision in the contract,
    the natural gas company withheld the maximum amount of
    liquidated damages allowable under the contract for the delay
    in the project’s completion. The natural gas company also
    refused to pay certain costs requested by the pipeline company

    related to the extra work orders. At the center of the lawsuit
    is whether the natural gas company should pay for the costs
    associated with the extra work and be allowed to withhold liq-
    uidated damages.
    II. FACTS
    1. Pleadings
    In January 2016, U.S. Pipeline, Inc., a corporation engaged
    in the business of constructing oil and gas pipelines and related
    energy infrastructure facilities, filed a complaint in the dis-
    trict court for Douglas County against Northern Natural Gas
    Company (Northern), a corporation headquartered in Omaha,
    Nebraska, and engaged in the business of providing natural gas
    transportation and storage services. U.S. Pipeline sought com-
    pensation under a pipeline replacement and relocation project
    contract for costs incurred to perform work that was outside of
    the original contract price (Extra Work). U.S. Pipeline sought
    relief under a breach of contract theory, as well as alternative
    theories, including claims for misrepresentation and fraudu-
    lent concealment.
    In response to U.S. Pipeline’s amended complaint, Northern’s
    answer and counter-complaint denied that it owed U.S.
    Pipeline any compensation for the Extra Work and resources
    U.S. Pipeline did not anticipate and denied any liability to
    U.S. Pipeline for U.S. Pipeline’s low bid. Northern’s counter-
    complaint further alleged that pursuant to the contract, U.S.
    Pipeline materially missed the substantial completion date and
    overbilled Northern for the work it performed. Based on this
    and a liquidated damages provision within the parties’ contract,
    Northern sought a declaratory judgment upholding Northern’s
    decision to withhold payment of $351,000 from U.S. Pipeline
    as liquidated damages. Northern also sought a declaration
    from the district court upholding Northern’s withholding of
    $320,000 in payment from U.S. Pipeline as a credit for U.S.
    Pipeline’s change in the construction plan that resulted in a
    cost savings.

    2. Summary Judgment
    Prior to trial, the court granted Northern partial summary
    judgment on the issue of whether U.S. Pipeline is entitled to
    indirect or consequential damages. The district court found
    that U.S. Pipeline admitted that it is not seeking damages for
    “indirect or consequential damages.” The district court over-
    ruled Northern’s motion for summary judgment on the remain-
    ing issues.
    3. Motions for Directed Verdict
    A bench trial was held pursuant to a jury waiver contained
    in the parties’ contract. At the close of U.S. Pipeline’s case,
    Northern moved for a directed verdict, asserting that (1) U.S.
    Pipeline’s damages were barred by the consequential damages
    waiver and (2) there was no genuine issue of fact on U.S.
    Pipeline’s misrepresentation/fraudulent concealment claims
    regarding “geotechnical information.” The court denied the
    motion. Northern later renewed the motion at the close of all
    the evidence, adding no further new grounds, and the court
    again denied the motion.
    4. Bench Trial
    The following evidence was adduced during the parties’
    2-week bench trial.
    (a) Bidding and Northern’s
    Original Project Plans
    In 2013, Northern decided to replace or relocate approxi-
    mately 29,450 feet, or 5.58 miles, of its Marquette main line
    (Marquette Replacement) and approximately 8,000 feet, or 1.52
    miles, of its Ishpeming branch line (Ishpeming Relocation)
    (collectively the Project), both located in the Upper Peninsula
    of Michigan.
    Northern designers prepared drawings for the Project.
    Northern’s construction drawings called for the installation
    of new underground piping using open-cut installation and
    horizontal directional drilling (HDD) techniques. Generally,
    - 449 -
    Nebraska Supreme Court A dvance Sheets
    303 Nebraska R eports
    U.S. PIPELINE v. NORTHERN NATURAL GAS CO.
    Cite as 
    303 Neb. 444
    underground pipeline is installed through either an open-cut
    process or HDD. For an open-cut installation, a trench is exca-
    vated and the pipe is placed in the bottom of the trench and
    covered. An HDD, in contrast, is a steerable, trenchless method
    of installing underground pipe in an arc along a prescribed bore
    path by using a surface-launched drilling rig. HDD drilling is
    more complicated and expensive to install.
    Specifically, Northern’s construction drawings called for
    six HDD’s—four locations along the Marquette Replacement
    (including the “Highway 476/Ely Creek” crossing) and two
    HDD’s on the Ishpeming Relocation (including the “Cliffs
    Road” crossing). In addition, each set of Northern’s drawings
    specified an arc radius of 525 feet on the 12-inch-diameter
    pipeline and 600 feet on the 6-inch-diameter pipeline. A gov-
    ernmental permit was granted for these specifications. The
    design arc radius or design radius of curvature is the radius
    of directional changes along the drill path. The arc radius is
    determined by several factors, including the desired distance
    between entry and exit points, the desired drill depth, direction
    changes for the drill path, and how much the drill stem and
    installed pipe can bend without being damaged.
    In March 2014, Northern opened the bid process for the
    Marquette Replacement and Ishpeming Relocation. Northern
    issued notice of a mandatory onsite, pre-bid meeting and route
    inspection to be held on May 13 and 14, 2014. One of the pur-
    poses for the route inspection was to walk the pipeline route to
    provide bidders a better understanding of the site conditions,
    project layout, and access issues. Three prospective bidders
    and their subcontractors, along with Northern representatives,
    attended the pre-bid meeting and route inspection.
    U.S. Pipeline sent Kris Osborn to represent U.S. Pipeline at
    the meeting and route inspection. Osborn drove to the pipeline
    on May 13, 2014, but he did not walk the route like other bid-
    ders. The meeting and route inspection continued on May 14,
    but Osborn did not attend. U.S. Pipeline’s representative who
    created its bid for the Project confirmed that he was informed

    U.S. PIPELINE v. NORTHERN NATURAL GAS CO.
    Cite as 
    303 Neb. 444
    that Osborn did not walk the pipeline route with the other bid-
    ders and Northern’s representatives.
    Northern used an online bid communication portal called
    Ariba to receive and transmit bid information to the interested
    bidders. Northern posted a summary of the meeting and route
    inspection on Ariba. Northern also posted the bid drawings, a
    form contract, the scope of work, questions and answers from
    bidders, meeting and route inspection notices, and summaries
    of meetings and inspections. U.S. Pipeline accessed the infor-
    mation posted on Ariba.
    Among the questions and answers posted on Ariba during
    the pre-bid phase included a bidder’s request that Northern
    “provide geotechnical information associated with the original
    12″ MIM10101 installation.” Northern responded by stating,
    “No geotechnical information associated with the original 12
    inch MIM10101 is available.” Broadly, geotechnical informa-
    tion is information about the geology and the estimated amount
    of rock in an area. This type of information provides insight
    as to the type of blasting that may be required for a drill-
    ing project.
    Another question posted on Ariba inquired:
    Without any geotechnical information, it is difficult at
    best to determine how much blasting, rock shield, or
    import padding to include in the bid.
    a. How many CY of ROW blasting does [Northern]
    want the Contractor to include in the bid?
    b. How many LF of ditch blasting does [Northern]
    want the Contractor to include in the bid?
    Northern replied, “[Northern] cannot speculate on the quantity
    and amount of blasting required for the [P]roject. The onsite
    visit was designed to familiarize bidders with the site condi-
    tions and bid accordingly.”
    In connection with its proposed work on the Project, Northern
    submitted “Resource Report No. 6” with the Federal Energy
    Regulatory Commission (FERC), the commission in charge
    of interstate pipeline construction and installation projects.

    U.S. PIPELINE v. NORTHERN NATURAL GAS CO.

    Compiled by an environmental consultant, Resource Report
    No. 6 estimated that excavators would encounter “approxi-
    mately 3.77 miles” of “shallow bedrock that may require blast-
    ing” along the portion to be replaced on the Marquette main
    line. Although Resource Report No. 6 was publicly available as
    part of Northern’s FERC filings, Northern did not post a copy
    of Resource Report No. 6 to Ariba. The contract eventually
    entered into with U.S. Pipeline, however, expressly advises that
    “[e]xtensive rock structures occur throughout the area.”
    In order for geotechnical information to be obtained, a
    “geotechnical survey” or investigation must be done. A “geo-
    technical survey” consists of taking exploratory borings to col-
    lect soil samples for classification and laboratory analysis. In
    creating Resource Report No. 6, Northern did not take or ana-
    lyze bore samples from the Project site. Rather, the report dis-
    cussed “geological data,” which is information that is publicly
    available from various sources, including a national resource
    bank of soil and rock information in the area.
    U.S. Pipeline and two other companies placed bids on the
    Project. Northern ultimately awarded the bid for both the
    Marquette Replacement and Ishpeming Relocation to U.S.
    Pipeline. U.S. Pipeline and Northern signed the contract at
    issue on July 24 and August 1, 2014, respectively.
    (b) Contract
    Under the contract, U.S. Pipeline agreed to fabricate, test,
    dewater, dry, and install approximately 29,450 feet (5.58 miles)
    of 12-inch-diameter pipeline for the Marquette Replacement
    and 8,000 feet (1.52 miles) of 6-inch-diameter pipeline for
    the Ishpeming Relocation. U.S. Pipeline and Northern agreed
    on a lump-sum price of $15,312,050 for the completion of
    the Project. Pursuant to the contract, the substantial comple-
    tion date for the Project was September 24, 2014. The parties
    expressly agreed that time was of the essence.
    The contract for the Project also provided that liqui-
    dated damages due to delayed completion of the Marquette
    - 452 -

    Replacement were to be set at $11,700 per day beyond the
    substantial completion date, with a cap of $351,000. The
    Ishpeming Relocation had a similar liquidated damages provi-
    sion, but it did not become applicable.
    Both parties agreed to a mutual waiver of indirect or con-
    sequential damages under the contract. The waiver’s language
    defines consequential damages as
    “INCLUDING BUT NOT LIMITED TO LOSS OF
    PROFIT, BUSINESS INTERRUPTION, LOSS OF
    REVENUE, LOSS OF USE, LOSS OF CONTRACT,
    LOSS OF THROUGHPUT, LOSS OF GOODWILL,
    INCREASED COST OF WORKING OR LOSS OF
    BUSINESS OPPORTUNITY[.]”
    The contract also contained provisions related to the omis-
    sion of contractually required work or performance of addi-
    tional work not specified under the contract, referred to as
    “Extra Work,” under the contract:
    [Northern] may omit work, or may require [U.S. Pipeline]
    to perform additional work or furnish additional materi-
    als or equipment, or the use thereof, in connection with
    the Work, which are not included in this Agreement
    (hereinafter referred to as “Extra Work”). Extra Work
    may be occasioned by material changes in Plans and
    Specifications or project lay out requiring additional
    work or materials of a different nature, kind and cost
    from that contemplated at the time of execution of this
    Agreement . . . .
    All requests for Extra Work must be prepared by [U.S.
    Pipeline] in the form attached as Exhibit “L” and approved
    in writing in advance by the [Northern] Representative or
    [Northern] Vice President of Operations. Such requests
    shall describe the work to be done and specify the com-
    pensation requested therefor . . . .
    With regard to payment for any Extra Work incurred, the
    contract set forth a payment schedule referred to as the “Force
    Account Work basis.” The provisions regarding payment for

    Extra Work incurred or work reduced from the contract are
    as follows:
    In the event unit prices as set forth in Part IV, or other
    agreed upon rates, are not applicable to any Extra Work,
    such work shall be paid for on the following basis, here-
    inafter referred to as the Force Account Work basis . . . .
    (i) [U.S. Pipeline’s] actual field payroll plus fifteen
    percent (15%) thereof for overhead and profit, plus [U.S.
    Pipeline’s] actual contribution or payment for insurance
    coverage, to the extent such are not subject to [Northern]
    provided insurance coverage, rated on basis of payroll,
    together with Social Security and unemployment tax or
    other employer’s tax contribution based on payroll, plus
    cost of union benefits; and
    (ii) Actual material costs, as evidenced by invoices
    from original suppliers or vendors showing [U.S. Pipeline]
    as purchaser, plus five percent (5%) thereof for [U.S.
    Pipeline’s] overhead and expenses, plus any applicable
    sales or use taxes assessed and paid in conjunction with
    such material purchases; and
    (iii) Charges for the actual use of equipment, includ-
    ing leased equipment, in accordance with the rate sched-
    ule set forth in [the Contract] or other agreed to rates
    included with the Contract Documents; and
    (iv) Charges for third party equipment or services
    as evidenced by their invoices, plus five percent (5%)
    thereof.
    All such billings for work on the Force Account Work
    basis shall comprise the total of charges accumulated
    under (i) through (iv) above and be supported by certi-
    fied daily payroll records initialed by the [Northern]
    Representative, a detailed list of material used, and any
    third party invoices.
    ....
    If changes in the Drawings, reports, or Plans and
    Specifications cause a decrease in [U.S. Pipeline’s] cost or

    time required for the completion of the Work, [Northern],
    by written notice to [U.S. Pipeline], may make a fair and
    proportionate adjustment therefor in [Northern’s] com-
    pensation to [U.S. Pipeline] and time allowed to complete
    the Work.
    If an Extra Work Request decreases the amount of
    Work to be done, such decrease shall not constitute
    the basis for a claim for damages or anticipated profits
    for Work affected by such decrease. [U.S. Pipeline’s]
    compensation shall be reduced to reflect the reduction
    in Work.
    The same section of the contract also provided that U.S.
    Pipeline would not be entitled to submit a claim for Extra
    Work or costs, expenses, or time to complete its contrac-
    tual obligations for delay or inefficiencies arising from
    U.S. Pipeline’s failure to carefully examine or inspect the
    sites or their conditions, the contract, and other various
    documentation.
    (c) Revision to Open Cut for
    Ishpeming Relocation
    At some point during the course of the Ishpeming
    Relocation, Northern decided to cancel the HDD of the Cliffs
    Road crossing and instead switch to an open cut. U.S. Pipeline
    agreed to the alteration but declined Northern’s request for
    a credit on the difference between the HDD and an open
    cut. Nevertheless, on their final payment, Northern withheld
    $320,000 from U.S. Pipeline as a credit for U.S. Pipeline’s
    cost savings attributable to performing an open cut at Cliffs
    Road instead of a more costly HDD bore.
    (d) Revisions for Highway 476/Ely Creek
    HDD Bore for Marquette Replacement
    In the course of the Marquette Replacement, Northern
    revised and redesigned the specifications for the Highway 476/
    Ely Creek HDD bore related to the Marquette Replacement.

    (i) Redesign of Highway 476/Ely Creek HDD
    Heavy rains had flooded a nearby wetland and increased
    its size via natural accretion. As a result, Northern became
    concerned that its original design for the Marquette main line
    would place the exit and entry points of the HDD too close
    to a wetland. Northern decided that it would need to revise
    the design for the Highway 476/Ely Creek HDD bore of the
    Marquette Replacement.
    The Highway 476/Ely Creek HDD revision extended the
    bore entry point beyond the swollen wetland and moved
    the exit point past a steep grade. Northern received FERC
    approval for the variance request regarding the Highway 476/
    Ely Creek HDD.
    Northern sent the revised Highway 476/Ely Creek HDD
    bore specifications to U.S. Pipeline on October 1, 2014. U.S.
    Pipeline began drilling the Highway 476/Ely Creek HDD in
    mid-October 2014.
    (ii) Revision Due to Power Lines
    On October 3, 2014, during the Marquette Replacement,
    Northern submitted a request to FERC to make another revi-
    sion to the Highway 476/Ely Creek Crossing HDD plans.
    Despite Northern’s having previously approved an open cut
    beneath power lines along the Marquette Replacement, a util-
    ity company objected to Northern’s original design. The utility
    company required Northern to either change the route of the
    open cut to be further away from power lines or use an HDD
    method (Power Line HDD). To accommodate the power lines,
    Northern again revised and redesigned its initial designs to
    reflect using the HDD method rather than an open cut at this
    location. Northern submitted these altered plans to FERC, and
    FERC approved the revision.
    (e) Change Orders
    U.S. Pipeline submitted “Change Order 14,” regarding the
    Power Line HDD, and “Change Order 15,” regarding Highway
    476/Ely Creek, to Northern on October 6, 2014. Both change

    orders were in the form that was referred to in the contract
    as “Exhibit L.” Northern approved Change Orders 14 and 15
    the following day. Change Orders 14 and 15 cite “Southeast
    Directional Drilling personnel and equipment” as the rea-
    son for the added cost components. Southeast Directional
    Drilling was the HDD subcontractor used by U.S. Pipeline on
    the Project.
    Additional time was not specifically requested in Change
    Order 14 or 15, nor were additional expenses for U.S. Pipeline
    specifically set forth in Change Order 14 or 15. U.S. Pipeline
    merely specified that a “lump sum” method of payment would
    be utilized to cover the subcontractor’s charges for the requested
    Extra Work. Northern’s construction coordinator on the Project
    admitted at trial that the work described in Change Orders 14
    and 15 constituted Extra Work under the contract.
    Following Northern’s approval of Change Orders 14 and
    15, U.S. Pipeline and its subcontractor signed a subcontract
    for the Extra Work, and the subcontractor mobilized to the
    Project site.
    The day before U.S. Pipeline began working on the Extra
    Work, U.S. Pipeline submitted “Change Order 19” to Northern.
    Change Order 19 pertained to the costs U.S. Pipeline antici-
    pated incurring as a result of having to retain extra crews and
    equipment for the Extra Work on the Highway 476/Ely Creek
    and Power Line HDD bores. Using the Force Account Work
    basis payment method pursuant to the contract, U.S. Pipeline
    estimated the additional cost of the Extra Work but did not spe-
    cifically indicate that U.S. Pipeline sought additional time for
    the task schedule or the substantial completion date.
    After receiving Change Order 19 from U.S. Pipeline,
    Northern gave U.S. Pipeline final approval to begin the Power
    Line HDD. When the Extra Work on Highway 476/Ely Creek
    and the Power Line HDD bores commenced, Northern knew
    U.S. Pipeline expected additional compensation for the Extra
    Work. At this point, Northern also knew that the Project was
    already past the substantial completion date.

    After the work commenced, in an email on October 24,
    2014, Northern disputed U.S. Pipeline’s numbers in Change
    Order 19. Northern suggested that U.S. Pipeline “submit
    a more equitable work change order that truly reflects the
    additional costs.” U.S. Pipeline stated that it would resubmit
    Change Order 19 once the HDD’s were completed to reflect
    actual costs. Northern did not respond to U.S. Pipeline’s offer
    to resubmit Change Order 19.
    In December 2014, Northern and U.S. Pipeline agreed to
    meet at Northern’s headquarters in Omaha to discuss several
    disputed and outstanding change orders, including Change
    Order 19. At the meeting, U.S. Pipeline provided documen-
    tation detailing its growing additional costs that related to
    the HDD Extra Work at issue in Change Order 19. Although
    the parties reached agreements regarding other various dis-
    puted change orders that are not the subject of this litigation,
    the parties were unable to reach an agreement on Change
    Order 19.
    (f) Completion of Project
    The last HDD was completed on December 16, 2014. U.S.
    Pipeline then proceeded with the remaining “original scope of
    work” included in the contract. For the Marquette Replacement,
    this work included hydrotesting the final bore pipe sections,
    drying the pipeline, performing the final tie-in welds on both
    sides of the bore, coating the welds, and backfilling.
    While U.S. Pipeline worked toward completing the Project,
    Northern representatives supervised U.S. Pipeline’s progress.
    It is undisputed that U.S. Pipeline did not substantially com-
    plete the Marquette Replacement until February 12, 2015. U.S.
    Pipeline issued its completion affidavit on August 21.
    The Extra Work added nearly 1,200 feet to the Highway
    476/Ely Creek crossing and a 500-foot bore for the Power
    Line HDD. The Extra Work, combined with severe winter
    conditions, delayed substantial completion of the Marquette
    Replacement by approximately 120 calendar days.

    (g) Supplements to Change Order 19
    On May 22, 2015, U.S. Pipeline submitted Change Order 19,
    “Supplement 1,” to Northern as Northern had requested in its
    October 24 response to U.S. Pipeline’s original Change Order
    19 request. Supplement 1 cited an “increase in the cost and
    time required for performance of the Work” due to the Extra
    Work on Highway 476/Ely Creek and the Power Line HDD.
    Supplement 1 requested delay and inefficiency damages of
    $7,740,138.75. Northern reviewed and rejected U.S. Pipeline’s
    Supplement 1, determining that U.S. Pipeline’s formula for
    costs was inaccurate and that certain items were missing.
    After Northern rejected Supplement 1, U.S. Pipeline sub-
    mitted Change Order 19, “Supplement 1A,” on July 16, 2015.
    Supplement 1A cited “additional compensation and time for
    performance of that changed Work” and requested delay and
    inefficiency damages of $6,729,980.79. After conducting an
    audit of U.S. Pipeline’s records, Northern again rejected U.S.
    Pipeline’s Supplement 1A.
    (h) Payment
    After making adjustments on other disputed change orders,
    Northern paid $17.3 million dollars to U.S. Pipeline, less
    $671,000 that it withheld for liquidated damages ($351,000)
    and a credit for the lower costs associated with the Cliffs Road
    modification ($320,000). U.S. Pipeline acknowledged that it
    underbid the Project, even with factoring in the wrong esti-
    mate of rock, and suffered a loss of $11.3 million.
    (i) U.S. Pipeline’s Expert Testimony Regarding
    Delay Attributions and Damages
    In addition to the evidence presented to establish the facts
    set forth above, U.S. Pipeline offered expert forensic testimony
    for the computation of damages under its breach of contract
    claim. U.S. Pipeline’s expert was William Berkowitz, a senior
    managing director in the construction solutions practice of
    a consulting firm, with an extensive background in forensic
    schedule and productivity analysis.
    - 459 -

    303 Nebraska R eports
    U.S. PIPELINE v. NORTHERN NATURAL GAS CO.
    Cite as 
    303 Neb. 444
    The general subject of Berkowitz’ testimony related to U.S.
    Pipeline’s breach of contract claim for Northern’s failure to
    pay for the Extra Work associated with Northern’s requested
    HDD redesigns. At the beginning of this testimony, Northern
    objected to U.S. Pipeline’s expert testimony on the basis
    of relevance under Neb. Evid. R. 401 and 403. Northern
    also objected on parol evidence grounds. The court overruled
    Northern’s objections. At the request of Northern, the trial
    court granted Northern a standing objection on these grounds
    as to the entirety of Berkowitz’ testimony.
    Berkowitz testified that he used the Force Account Work
    basis found within the contract to calculate the costs and dam-
    ages associated with the Extra Work. Berkowitz testified that
    he calculated the increased costs associated with the Extra
    Work to total $5,275,506.01. Berkowitz’ report notes that
    this amount represents the added delays and inefficiencies
    related to the addition of the Extra Work from October 2014
    through February 2015. In his calculations, Berkowitz found
    that there was a total delay of 141 days to the substantial
    completion date. Of these 141 days, he computed that 123
    of these days were attributed to Northern’s HDD redesign
    and therefore compensable to U.S. Pipeline. The 18 days of
    delay that Berkowitz attributed to U.S. Pipeline were due
    to a late start of construction and late mobilization of U.S.
    Pipeline’s subcontractor.
    In calculating damages, Berkowitz used a multistep process.
    First, he determined the actual schedule impact of the Extra
    Work, comparing the parties’ original schedule to the schedule
    that actually occurred. Berkowitz then quantified which costs
    were attributable to the addition of the Extra Work, as opposed
    to costs that would have otherwise occurred. Again, in doing
    so, he testified that he utilized the Force Account Work basis
    from the parties’ contract. Lastly, Berkowitz testified that he
    deducted payments that were actually made by Northern dur-
    ing the Project. Berkowitz did not include any costs associated
    with U.S. Pipeline’s claims for negligent misrepresentation or
    - 460 -

    U.S. PIPELINE v. NORTHERN NATURAL GAS CO.
    Cite as 
    303 Neb. 444
    fraudulent concealment regarding geotechnical information in
    his damages analysis.
    Berkowitz testified that in his analysis quantifying which
    costs were attributable to each party, he separated U.S.
    Pipeline’s costs into two categories: “delay costs” and “inef-
    ficiency” costs, or “unproductive work”/“downtime” costs. In
    his testimony, Berkowitz specifically defined “delay costs” as
    time-related costs for activities and materials that must con-
    tinue for the entire duration of a project and are not necessarily
    task specific, such as supervision, temporary heating, and fuel
    costs. Berkowitz defined “inefficiency costs” or “unproductive
    work/downtime” as costs stemming from tasks that took longer
    or were more expensive because of Northern’s design changes
    and U.S. Pipeline’s having to continue its labors on the Project
    amidst the intemperate Michigan winter. These additional
    costs, Berkowitz asserted, were largely a result of the Extra
    Work. His testimony and report supported this conclusion,
    finding in his analysis that most construction was completed by
    the time Northern finally told U.S. Pipeline to move forward
    with the redesigned projects. While Northern cross-examined
    Berkowitz concerning his calculations under the Force Account
    Work basis, Northern did not object to Berkowitz’ testimony on
    foundation grounds.
    Berkowitz’ final opinion was that, applying the Force
    Account Work basis as set forth in the contract, U.S. Pipeline
    incurred a total of $5,275,506.01 in costs related to performing
    the HDD Extra Work.
    (ii) Northern’s Expert Testimony Regarding
    Delay Attributions and Damages
    Northern offered contrary expert testimony from a con-
    sultant for construction disputes, Anthony Gonzales. Like
    Berkowitz, Gonzales testified that the delays for the Project
    totaled 141 days. However, Gonzales opined that these delays
    were entirely attributable to U.S. Pipeline. Gonzales did not
    address the accuracy of Berkowitz’ calculations for the 123
    - 461 -

    303 Nebraska R eports
    U.S. PIPELINE v. NORTHERN NATURAL GAS CO.
    Cite as 
    303 Neb. 444
    days Berkowitz testified were attributable to Northern’s HDD
    redesign on the contract’s Force Account Work basis.
    Gonzales testified that solely U.S. Pipeline’s own actions
    or inactions prevented it from maintaining its productivity
    throughout the Marquette Replacement portion of the Project.
    Gonzales concluded that as a result, U.S. Pipeline is respon-
    sible for at least $351,000 in liquidated damages per the liq-
    uidated damage provision in the contract and U.S. Pipeline
    was not entitled, under the terms of the contract, to any
    damages for the Extra Work. However, Gonzales noted that
    if the contract were not followed, Northern might be respon-
    sible for $345,700 in damages to U.S. Pipeline for 20 days of
    delay attributable to Northern’s HDD redesign and subsequent
    Extra Work.
    5. District Court Order
    Following the conclusion of the bench trial, the district court
    awarded judgment in favor of U.S. Pipeline on its claim for
    breach of contract against Northern. Noting that Berkowitz’
    methodology and calculations were credible and reliable, the
    court adopted Berkowitz’ calculation of costs associated with
    the Extra Work based on the Force Account Work basis. The
    district court summarized Berkowitz’ testimony as follows:
    Berkowitz calculated the increased costs associated with
    the Extra Work to total $5,275,506.01. . . . This amount
    represents the added delays and inefficiencies which
    attended the Extra Work from October 2014 through
    February 2015. The delay costs stem from the fact that
    by the time [Northern] authorized the Extra Work, [U.S.
    Pipeline] had largely completed its work on the Project.
    But for the Extra Work, [U.S. Pipeline] could have sig-
    nificantly reduced its workforce on site and completed
    the Project by the end of October. The inefficiency costs
    stem from [U.S. Pipeline] having to continue its labors
    on the Project amidst the intemperate Michigan win-
    ter which slowed its progress. But for the Extra Work,
    - 462 -

    303 Nebraska R eports
    U.S. PIPELINE v. NORTHERN NATURAL GAS CO.
    Cite as 
    303 Neb. 444
    [U.S. Pipeline] would not have had to contend with win-
    ter conditions.
    The court also partially granted Northern’s request for a
    declaratory judgment, stating that Northern was justified under
    the contract to withhold payment from U.S. Pipeline as a credit
    for U.S. Pipeline’s cost savings attributable to performing an
    open cut at the Cliffs Road crossing instead of a more costly
    HDD. However, the court awarded U.S. Pipeline $23,729.06
    after it found that the proper amount attributable to such cost
    savings was $296,270.94 and not $320,000.
    Regarding liquidated damages, the district court found that
    Northern improperly withheld $351,000 in liquidated dam-
    ages per the contract cap due to delays beyond the substantial
    completion date. The court concluded that Northern waived its
    rights to these liquidated damages under the contract, because
    Northern failed (1) to indicate that the liquidated damages
    clause would still be enforced even after requesting Extra
    Work and (2) to send the revised plans for the Extra Work until
    October 1, 2014, after the substantial completion date. As a
    result, Northern’s request for a declaratory judgment declaring
    that it had a right under the contract to withhold $351,000 from
    U.S. Pipeline as liquidated damages was denied.
    U.S. Pipeline was awarded damages in the amount of
    $5,275,506.01 for the Extra Work it performed, and an addi-
    tional $374,729.06 ($351,000 + $23,729.06) for the amount
    Northern wrongly withheld, for a total damage award of
    $5,650.235.07. The court dismissed the remainder of both par-
    ties’ claims with prejudice.
    III. ASSIGNMENTS OF ERROR
    Northern assigns that the district court erred in (1) awarding
    U.S. Pipeline consequential damages on its breach of contract
    claim, because the contract prohibits such recovery; (2) deny-
    ing Northern’s motion for directed verdict; (3) admitting and
    failing to strike the testimony of U.S. Pipeline’s expert wit-
    ness that included damages for certain work and conditions

    that were expressly assumed by U.S. Pipeline or barred under
    the contract; and (4) dismissing Northern’s claim for liqui-
    dated damages.
    IV. STANDARD OF REVIEW
    [1] In a bench trial of an action at law, the trial court is the
    sole judge of the credibility of the witnesses and the weight to
    be given their testimony;1 an appellate court will not reevalu-
    ate the credibility of witnesses or reweigh testimony but will
    review the evidence for clear error.2
    [2] Similarly, the trial court’s factual findings in a bench
    trial of an action at law have the effect of a jury verdict and
    will not be set aside unless clearly erroneous.3
    [3] In reviewing a judgment awarded in a bench trial of a law
    action, an appellate court considers the evidence in the light
    most favorable to the successful party and resolves evidentiary
    conflicts in favor of the successful party, who is entitled to
    every reasonable inference deducible from the evidence.4
    [4] In reviewing rulings on motions for directed verdict and
    judgments notwithstanding the verdict, we give the nonmoving
    party the benefit of all evidence and reasonable inferences in
    his or her favor, and the question is whether a party is entitled
    to judgment as a matter of law.5
    [5] The meaning of a contract is a question of law, in
    connection with which an appellate court has an obligation
    to reach its conclusions independently of the determinations
    made by the court below.6

    V. ANALYSIS
    1. Consequential Damages
    Northern contends that the district court erred in deny-
    ing Northern’s motion for directed verdict and by entering
    judgment in favor of U.S. Pipeline for $5,275,506.01, which
    it describes as being an award of consequential damages.
    Northern argues that the court erred in denying its original
    and renewed motions for directed verdict and in awarding
    “consequential” damages to U.S. Pipeline, because the parties
    agreed to a mutual waiver of consequential damages within
    their contract.
    The underlying issue of Northern’s first two assignments
    of error relates to the proper characterization of the damages
    awarded. Stated differently, the central question is whether
    any portion of the damages awarded by the district court was
    consequential damages. The issue of whether damages are

    consequential under a contract is a question of law that we
    review de novo,11 but the factual determinations underlying
    such a characterization are reviewed for clear error.12 In a
    bench trial of an action at law, the trial court is the sole judge
    of the credibility of the witnesses and the weight to be given
    their testimony.13 Similarly, the trial court’s factual findings
    in a bench trial of an action at law have the effect of a jury
    verdict and will not be set aside unless clearly erroneous.14 We
    find that the damages alleged by U.S. Pipeline and awarded by
    the district court were properly characterized as direct damages
    and were not consequential damages.
    [9] Nebraska courts have consistently upheld the right of
    contracting parties to privately bargain for the amount of dam-
    ages to be paid in the event of a breach of contract.15 This
    court has explained that “‘parties to a contract may override
    the application of the judicial remedy for breach of a con-
    tract’” by bargaining in advance over the amount or type of
    damages to be paid in the event of breach.16 Many jurisdictions
    apply this principle to waivers of consequential damages, as
    these contractual provisions that purport to waive consequen-
    tial damages seek to carve out a specific category of damages
    for which recovery is denied.17 Generally, a contractual waiver

    or exclusion of consequential damages will be upheld unless
    the provision is unconscionable.18
    The parties do not dispute the existence of the waiver of
    consequential damages in the contract. Nor does U.S. Pipeline
    argue that the waiver is unconscionable. Rather, the dispute
    lies with the provision’s relevance. Northern asserts that the
    contract’s waiver of consequential damages is controlling and
    dispositive because the damages alleged and awarded were
    consequential, whereas U.S. Pipeline argues that the provi-
    sion is irrelevant because the damages alleged and awarded
    were direct results of the Extra Work Northern requested U.S.
    Pipeline to complete under the contract.
    The waiver at issue in this case stated that consequential
    damages were
    “INCLUDING BUT NOT LIMITED TO LOSS OF
    PROFIT, BUSINESS INTERRUPTION, LOSS OF
    REVENUE, LOSS OF USE, LOSS OF CONTRACT,
    LOSS OF THROUGHPUT, LOSS OF GOODWILL,
    INCREASED COST OF WORKING OR LOSS OF
    BUSINESS OPPORTUNITY[.]”
    Thus, the provision states what kinds of damages would be
    included under the umbrella of consequential damages rather
    than addressing the cause of those damages and when they
    might be deemed consequential rather than direct. The con-
    tract does not define direct damages. Further, the terms of
    this “definition” do not purport to change the common-law
    definition of “consequential damages.” Based on this, we, like
    the parties, rely on the common law to clarify the meaning of
    the term.
    [10,11] Consequential damages, as opposed to direct dam-
    ages, do not arise directly according to the usual course of
    things from a breach of contract itself.19 Rather, they occur

    as a consequence of special extracontractual circumstances
    known or reasonably supposed to have been contemplated
    by the parties when the contract was made.20 Direct damages
    refer to those which the party lost from the contract itself—in
    other words, the benefit of the bargain—while consequential
    damages refer to economic harm beyond the immediate scope
    of the contract.21 One common example of consequential dam-
    ages is the lost profits or revenues from outside parties, lost
    business opportunities, or other sums forgone as a result of a
    breach of contract.22
    The parties do not disagree as to the definition of con-
    sequential damages, but, rather, as to its application to the
    facts of this case. Northern relies on Creighton University
    v. General Elec. Co.23 in support of its argument that the
    damages at issue in this case are consequential as opposed
    to direct damages. In Creighton University, the plaintiff was
    damaged when it was unable to collect $2.4 million in bill-
    ings because of “delayed implementation” of a healthcare
    technology system by the defendant.24 The plaintiff argued
    that these losses were direct damages because they “‘were
    naturally expected to follow from breach of the [parties’ con-
    tract] because the net billings would have been collected had
    the System been able to process claims in a timely manner

    . . . .’”25 The U.S. District Court for Nebraska rejected
    this argument. Applying Nebraska law, the court repeated
    the proposition that consequential damages do not arise
    directly according to the usual course of things from the
    breach itself; rather, they occur as a consequence of special
    circumstances known or reasonably supposed to have been
    contemplated by the parties when the contract was made.26
    The court then concluded that “[l]abeling the $2.4 million
    in uncollected claims ‘direct damages’ does not make them
    so. In fact, the allegation that the claims were uncollectible
    because they were not submitted within deadlines established
    by payors shows that the loss of income was attributable to
    special circumstances.”27
    Northern attempts to argue that Creighton University is
    similar to this case, because U.S. Pipeline is seeking to improp-
    erly “label” the damages it seeks as “direct” damages. Thus,
    Northern asserts that U.S. Pipeline seeks to ignore the mutual
    waiver of consequential damages in the contract and recover
    damages for the indirect consequences of the alleged delay or
    inefficiencies incurred on the Marquette Replacement.
    We find no merit in Northern’s argument. Creighton
    University is notably distinguishable from the case at bar. In
    Creighton University, the “consequential” damages that the
    plaintiff was barred from seeking were collections from third
    parties, which plaintiff was unable to collect because of those
    deficiencies (“lost income” based on “projected cashflow”)—
    not payments due to the plaintiff under the contract for services
    rendered. The damages incurred in Creighton University were
    the result of lost income or lost business opportunities, which
    are clearly consequential damages.
    In contrast, the damages incurred by U.S. Pipeline and
    awarded by the district court were simply the revenue due to

    U.S. Pipeline under the contract for the work performed. At
    the time Northern authorized the Extra Work to go forward,
    it agreed to compensate U.S. Pipeline to perform that Extra
    Work on a modified time-and-materials basis, called the Force
    Account Work basis under the contract. This was the basis
    that the district court determined was utilized by Berkowitz in
    his calculations. The damages were composed of a subset of
    the actual, out-of-pocket costs it incurred as a direct result of
    Northern’s HDD-related changes and contractual markups from
    the Force Account Work basis calculations when applicable.
    U.S. Pipeline did not seek profits or revenues it lost from third
    parties or lost business opportunities, or any other sums it had
    to forgo as the result of the Extra Work. Rather, the district
    court properly awarded U.S. Pipeline only the benefit of its
    bargain: the recovery of payments owed to it for fulfilling its
    obligations under the contract, including completing the HDD
    Extra Work ordered by Northern. These damages flow directly
    from the contract.
    The value of the bargain to U.S. Pipeline was exactly what
    it sought in damages in the trial court: the time and materials it
    expended to complete the Extra Work, however long that took,
    calculated with the small markups allowed under the contract.
    Direct damages reflect a failure on the part of the defendant
    to live up to the bargain it made, or a failure of the promised
    performance itself.28 Here, Northern failed to remit payment
    to U.S. Pipeline pursuant to Extra Work completed directly
    pursuant to the contract. The damages sought by U.S. Pipeline
    are precisely what direct damages are defined to be, and
    the parties’ contractual provision does not purport to change
    this definition.
    Accordingly, we find that the damages sought by, and sub-
    sequently awarded to, U.S. Pipeline were a direct result of the
    parties’ contractual agreement. We find no merit to Northern’s

    argument that the district court erred by awarding consequen-
    tial damages.
    2. A dmissibility of Berkowitz Testimony and
    Northern’s Motions on Directed Verdict
    We also find no merit to Northern’s arguments that the
    district court abused its discretion by admitting and failing to
    strike Berkowitz’ testimony which allegedly included in his
    damages calculations certain work and conditions expressly
    assumed by U.S. Pipeline or barred under the contract and
    that the court erred in denying Northern’s motion for directed
    verdict based on these same alleged deficiencies in Berkowitz’
    testimony.
    Northern’s first argument in this regard is little more than
    a restatement of its assertion that Berkowitz failed to separate
    any direct damages from consequential damages. As noted
    above, the damages requested by U.S. Pipeline and subse-
    quently awarded by the district court were direct damages
    and not consequential damages. Based on this conclusion, we
    must also conclude that the district court properly admitted
    and considered Berkowitz’ testimony as relevant regarding the
    calculation of damages.
    Northern’s second argument is that the court should have sus-
    tained Northern’s objections to Berkowitz’ testimony, because
    Berkowitz’ calculation contained “other damages” that U.S.
    Pipeline could not recover under the contract.29 These “other
    damages” that Northern argues are not contractually compen-
    sable include compensation for (1) an 18-day holiday break
    that U.S. Pipeline took during December 2014 and January
    2015; (2) days in which U.S. Pipeline was performing “correc-
    tive” work30; (3) costs and delays associated with subsurface
    conditions, which were risks assumed by U.S. Pipeline under
    the contract; and (4) costs and delays associated with work

    previously compensated for under Change Orders 14 and 15.
    Northern asserted in its reply brief and at oral argument that
    Berkowitz did not utilize the Force Account Work basis as per
    the contract’s requirements when he calculated U.S. Pipeline’s
    damages, but Northern did not specifically assign and specifi-
    cally argue this in its initial brief.
    Northern makes a similar argument in support of its assign-
    ment that the court erred in failing to grant its motions for
    directed verdict. Northern argues that Berkowitz’ calculations,
    the only evidence supporting U.S. Pipeline’s damages calcula-
    tion, were incorrect because Berkowitz included delay dam-
    ages that were not attributable to Northern in his calculation.
    Based on this, Northern asserts that U.S. Pipeline failed to
    prove damages.
    [12,13] We find that Northern failed to preserve the errors
    regarding the methodology and particulars of Berkowitz’ cal-
    culations. Unless an objection to offered evidence is suf-
    ficiently specific to enlighten the trial court and enable it to
    pass upon the sufficiency of such objection and to observe the
    alleged harmful bearing of the evidence from the standpoint
    of the objector, no question can be presented therefrom on
    appeal.31 At trial, Northern made only the following objection
    relative to Berkowitz’ testimony: “I object on relevancy, 401,
    403, as well as parole [sic] evidence. This testimony is not
    consistent with the contractor — the change orders that were
    signed, and so I object on that basis.” Northern’s objection was
    not sufficiently specific to alert the trial court that it contested
    the details or methodology of Berkowitz’ calculations, which
    Northern now takes issue with on appeal. An issue not prop-
    erly presented and passed upon by the trial court may not be
    raised on appeal.32

    ment that the court erred in admitting Berkowitz’ testimony

    because his calculations did not use the Force Account Work
    basis, Northern failed to preserve this argument by failing to
    assign it as error and argue it in its initial brief. In order to be
    considered by an appellate court, an alleged error must be both
    specifically assigned and specifically argued in the brief of the
    party asserting the error.33 Errors not assigned in an appellant’s
    initial brief are thus waived and may not be asserted for the
    first time in a reply brief.34
    In any event, the district court made a factual finding that
    the Force Account Work basis was properly used throughout
    Berkowitz’ calculations. The court found Berkowitz’ testi-
    mony credible and reliable. And the district court determined
    that all costs included in Berkowitz’ calculations were com-
    pensable to U.S. Pipeline as damages incurred pursuant to
    Northern’s breach of contract on the Force Account Work
    basis. With respect to damages, an appellate court reviews the
    trial court’s factual findings under a clearly erroneous standard
    of review.35 We cannot say that the district court’s finding
    that Berkowitz’ calculations were proper under the contract is
    clearly erroneous.
    With respect to its directed verdict arguments, Northern
    failed to preserve these arguments because they were not
    presented below in support of the motions for directed ver-
    dict. Instead, in support of its motions for directed verdict,
    Northern argued that (1) U.S. Pipeline’s damages were barred
    by the consequential damages waiver and (2) there was
    no genuine issue of fact on U.S. Pipeline’s misrepresenta-
    tion/fraudulent concealment claims regarding “geotechnical
    information.”

    directed verdict, the appellate court should consider solely
    those grounds urged by the appellant to the trial court in

    support of its directed verdict motion.36 If a party fails to set
    forth certain arguments as grounds in a motion and renewed
    motion for directed verdict, such arguments will not be prop-
    erly preserved for appeal.37 The arguments that Northern makes
    on appeal concerning the particulars of Berkowitz’ calculations
    were not presented below. They were not set forth as grounds in
    Northern’s motions for directed verdict.38 As such, we decline
    to address Northern’s additional arguments on this point.
    We note that Northern did not assign or argue that the evi-
    dence was insufficient to support the district court’s judgment
    and award of damages in favor of U.S. Pipeline. However,
    based on the totality of our findings above, and viewing the
    evidence, including Berkowitz’ testimony, in the light most
    favorable to U.S. Pipeline, it is apparent that the evidence
    was sufficient.
    Based on the analysis above, we find that the district court
    did not err in (1) admitting and relying upon the entirety of
    Berkowitz’ testimony and (2) denying Northern’s motions for
    directed verdict.
    3. Northern’s Claim for
    Liquidated Damages
    Lastly, Northern assigns that the district court erred in deny-
    ing Northern’s request for a declaratory judgment declaring
    that it had a right under the contract to withhold $351,000 from
    U.S. Pipeline as liquidated damages for U.S. Pipeline’s failure
    to meet the September 24, 2014, substantial completion date.
    Northern contends that because U.S. Pipeline did not request
    any additional time or a modification of the substantial com-
    pletion date, the target completion date remained September
    24. Because the actual substantial completion date occurred
    on February 12, 2015, Northern asserts that it was entitled to

    withhold the full liquidated damages cap amount as set forth
    within the contract.
    In its order, the district court determined that because
    Northern did not send the revised plans for the Extra Work
    until October 1, 2014, Northern effectively waived its right to
    seek liquidated damages under the contract. Because of this
    delay, Change Orders 14, 15, and 19 were also submitted after
    the substantial completion date.
    [18-22] The determination of whether a contractual provi-
    sion has been waived is a factual determination.39 A contractual
    provision for liquidated damages for delay in performance
    may be waived.40 Waiver is a voluntary and intentional relin-
    quishment or abandonment of a known existing legal right or
    such conduct as warrants an inference of the relinquishment
    of such right.41 In order to establish a waiver of a legal right,
    there must be clear, unequivocal, and decisive action of a party
    showing such purpose, or acts amounting to estoppel on his
    or her part.42 A written contract may be waived in whole or
    in part, either directly or inferentially, and the waiver may be
    proved by express declarations manifesting the intent not to
    claim the advantage, or by so neglecting and failing to act as
    to induce the belief that it was the intention to waive.43 Even
    a provision in a written contract that specifies that a waiver of
    the conditions and terms of the agreement must be in writing
    may be waived by acts or conduct.44
    We agree with the district court’s analysis of this matter.

    damages because it neglected to request additional time on its
    change orders is unfounded. By requesting the Extra Work,
    submitting the designs after the passing of the substantial
    completion date, and further failing to inform U.S. Pipeline
    that it intended to enforce the liquidated damages provision in
    the contract, Northern manifested a clear intent to waive the
    contractual liquidated damages provision. Northern knowingly
    requested Extra Work that would clearly exceed the substan-
    tial completion date. The district court’s determination that
    Northern’s conduct amounted to a waiver was supported by the
    evidence and cannot be said to be clearly wrong.
    Northern alternatively argues that the court should have
    awarded liquidated damages to Northern for three delays it
    alleges were attributable solely to U.S. Pipeline: (1) U.S.
    Pipeline’s holiday break in December 2014 and January 2015,
    (2) U.S. Pipeline’s corrective work on the pipe replacement
    in January 2015, (3) and U.S. Pipeline’s execution of work
    performed for Change Orders 14 and 15 from October 15 to
    December 16, 2014. However, Northern fails to argue why the
    waiver the district court found to have occurred as to the liqui-
    dated damages provision would apply with lesser force to these
    specific time periods.
    The district court did not err in denying Northern’s request
    for a declaratory judgment upholding its decision to withhold
    $351,000 in liquidated damages.

    For the reasons set forth above, we affirm the decision of the
