Introduction
Appellant Jokerst, Inc. (Jokerst), was the general contractor on a construction project, and Respondent Kluesner Con-creters (Kluesner) provided concrete work for the project as a subcontractor. The parties disputed the terms of their' contract, and the trial court found in favor of Kluesner, ordering Jokerst to pay the balance due on Kluesner’s invoices. Jokerst argues it had paid Kluesner the full lump sum amount of their agreement. We reverse in part, affirm in part, and affirm the result.
Background
In 2009, the City of Cape Girardeau (City) requested bids for general contractors to complete a construction project called the Cape Splash Aquatic Center (Cape Project). In preparing its bid to submit to the City, Jokerst requested a bid from Kluesner for concrete work as a sub
Using the information Jokerst provided, Kluesner prepared a two-page bid, which Kluesner submitted to Jokerst by fax. The top of each page listed the word “Estimate.” The total price for the work, listed at the bottom of the second page of the bid, was $104,747.40. Besides form information contained on both pages, the only other information on the second page was a short paragraph containing the following wording:
This bid is good for thirty days after the above date. Final billing to be based upon actual measurements of completed work.
Kluesner’s bid was dated May 1, 2009.
On May 29, 2009, Jokerst sent a fax (May 29 Fax) to Kluesner containing the following statements:
We were the low bidder for [the Cape] Project. We have received a notice to proceed on the Project.
Your bid of $104,747.40 was used for concrete for the job. This project was a lump sum contract. If you have any questions please call. We are looking forward to working with you.
In September of 2009, Kluesner began work on the Cape Project. Kluesner submitted an invoice that month and another in November of 2009. These invoices listed measurements for work completed, the unit price for each type of construction, and a total amount billed for the work completed as of the date of each invoice. Jokerst paid the amounts listed on both invoices, a total of $45,883.73.
In April 2010, Jokerst asked Kluesner to change construction of a particular curb for the Cape Project.
Kluesner sent two additional invoices to Jokerst, dated April 27, 2010, and May 11, 2010. Each invoice contained the heading “Extra Work Order,” underneath which was a line item for the portion of the stand-up curb that had been completed along with the unit price, $30.00 per lineal square foot. Jokerst paid for each item listed on the invoices except those for the stand-up curb. This left a difference of $24,090.00 Kluesner noted as remaining due from those invoices.
After Jokerst completed the Cape Project, Jokerst sent a check to Kluesner for $1,349.82, which represented the amount Jokerst had determined was still due to Kluesner based on Kluesner’s original total bid price.
Kluesner asserted claims in contract and in quantum meruit. Jokerst argued it had fulfilled the terms of the parties’ contract for a lump sum amount. Kluesner argued that the contract was not for a lump sum, but for the unit prices of the work actually completed. The trial court found that no lump sum contract existed, and that a contract for the unit prices contained in Kluesner’s bid was created when the City accepted Jokerst’s bid. The trial court also found that Jokerst did not make proper inquiries related to the price of the stand-up curb and what was necessary for submitting a change order in order to be compensated by the City for the additional cost. The trial court found that Jokerst benefitted from the stand-up curb because it allowed for easier completion of other portions of the Cape Project. Thus, the trial court concluded, Jokerst must pay the remaining amount due to Kluesner for the stand-up curb, $21,738.03.
Discussion
Jokerst raises four points on appeal. In Point I, Jokerst argues the trial court erred in concluding that a contract existed between the parties for the unit prices contained in Kluesner’s bid, and alternatively that the trial court erred in not accepting Jokerst’s affirmative defenses of waiver and accord and satisfaction. Jok-erst argues in its second point that the trial court erred in granting relief in quantum meruit because Jokerst did not receive any benefit from the stand-up curb and was not unjustly enriched. Jokerst argues in Point III that the judgment is ambiguous and inconsistent in that it fails to distinguish between the two claims Kluesner raised, and the judgment improperly grants Kluesner combined relief under two alternative theories of recovery. Finally, in Point IV, Jokerst argues that the trial court erred in granting Kluesner prejudgment interest because the parties’ differing views of the contract between them resulted in unliquidated damages.
Standard of Review
Our review of court-tried cases is governed by the standard set forth in Murphy v. Carrón,
Point I
Jokerst argues the trial court erred in concluding that Jokerst’s use of Kluesner’s bid and the City’s subsequent award of the Cape Project to Jokerst formed a contract between Jokerst and Kluesner for the unit prices contained in Kluesner’s bid. We agree.
Normally, a general contractor’s use of a subcontractor’s bid does not in itself form a contract, even when the general contractor is subsequently awarded the project. See generally 1 Corbin on Contracts § 2.31 (Rev. ed.1993). There may be an exception where there is evidence of a definite, uniform, and known practice, whereby the use of a subcontractor’s bid by a general contractor constitutes acceptance and creates a contract. Accord Sharp Bros. Contracting Co. v. Commercial Restoration, Inc.,
Absent such evidence, Missouri courts have at times used the doctrine of promissory estoppel to require a subcontractor’s performance when a general contractor has relied on the subcontractor’s bid and is awarded the general contract. See Branco Enters., Inc. v. Delta Roofing, Inc.,
However, here we face the converse situation. Kluesner did not attempt to avoid the terms of its bid; rather, Kluesner performed the work and sought to have its bid terms enforced against the general contractor. Yet, in such a context, we have found no Missouri court finding existence of a contract or a promise enforceable against a general contractor created simply by the general contractor’s use of the subcontractor’s bid. In fact, the contrary is true. See generally 1 CoRbin § 2.31 (noting no mutuality of obligation: though subcontractor may be bound when general contractor uses subcontractor’s bid, does not follow that general contractor must hire subcontractor if awarded project). This is because the general contractor’s simple use of a subcontractor’s bid is not analogous to the promise to perform if accepted contained in the subcontractor’s bid. A general contractor, by soliciting bids, makes no promise inviting detrimental reliance to a subcontractor because there is no guarantee the general contractor will be awarded the project.
However, in certain circumstances where a subcontractor can show more than just the general contractor’s use of the bid, a court may find promissory estoppel operates to bind a general contractor. For example, if the subcontractor can show that the general contractor made a promise to the subcontractor to hire the subcontractor if awarded the project, a court may use promissory estoppel to enforce the general contractor’s promise in those cases. See Elec. Constr. & Maint. Co. v. Maeda Pac. Corp.,
Here, there was no evidence of a uniform and definite practice whereby Jok-erst’s use of Kluesner’s bid created a contract binding both parties upon the City’s acceptance of Jokerst’s bid. Additionally, there was no evidence that Jokerst made a definite promise to hire Kluesner if Jok-erst received the contract from the City. See Clevenger v. Oliver Ins. Agency, Inc.,
Jokerst goes on to argue that in fact a contract for Kluesner to perform the concrete work for a lump sum amount existed, as evidenced by Jokerst’s May 29 Fax and Kluesner’s subsequent performance of the concrete work. In contrast, Kluesner argues that the May 29 Fax manifested assent to the terms of Kluesner’s bid and created a contract based on the bid terms. We find this question irrelevant to the present appeal, as the sole damage award at trial was for the cost of the stand-up curb, which was included in neither alleged contract.
“Extra work” is work that is neither contemplated by the parties nor controlled by the contract. Uhle v. Tarlton Corp.,
As such, the stand-up curb was “extra work.” See Uhle,
The trial court made findings supported by substantial evidence that Jokerst requested the change in the curb and did not inquire about whether such change would result in a difference in price. Kluesner completed the stand-up curb. The parties dispute whose responsibility it was to ensure the change in price was known and who was responsible for completing any change order. However, there is no evidence of any contract term between Klues-ner and Jokerst addressing extra work or assigning burdens of communication to either party, and we cannot do so here.
In light of these facts, we find no oral or written contract existed between Kluesner and Jokerst for the stand-up curb. See Envtl. Waste Mgmt., Inc. v. Indus. Excavating & Equip., Inc.,
Point II
Jokerst next argues that the trial court erred in granting Kluesner recovery in quantum meruit because Jokerst was not unjustly enriched. We disagree.
Where there is no formal contract, a promise to pay for services or materials may be implied by the law. This is referred to as quasi-contract or quantum meruit. See Green Quarries, Inc. v. Raasch,
Jokerst argues that it received no unjust enrichment from the stand-up curb, but rather it is the City that retained the curb and derived benefit from it. However, in construction contexts, “courts have repeatedly looked to whether the landowner has already paid the general contractor the amount due the general contractor under their express contract.” County Asphalt Paving,
Nonetheless, Jokerst asserts that it was not paid by the City for the stand-up curb due to Kluesner’s failure to provide adequate information so that Jokerst could submit a change order. Jokerst argues that Kluesner therefore waived its right to payment for the stand-up curb. However, the trial court found that Jokerst failed to timely request such information. Furthermore, Kluesner had no contractual obligation to ensure Jokerst fulfilled Jokerst’s own obligation to the City regarding a change order, and Jokerst may not now shift its obligation to Kluesner. It is impossible to waive a right by failing to fulfill a nonexistent contractual obligation.
In such cases, courts have allowed subcontractors to maintain causes of action against general contractors. See, e.g., County Asphalt Paving,
Here, the trial court found Jokerst requested the stand-up curb. Kluesner provided the stand-up curb as requested, and the stand-up curb had value. Despite Kluesner’s demands for payment, Jokerst did not pay Kluesner for the stand-up curb. Todd Kluesner, president and owner of Kluesner, testified that he researched the prevailing rate for stand-up curbs in the area. He testified that the third party he had contacted told him that the prevailing rate was $40 per lineal square foot, which is $10 more per lineal square foot than Kluesner charged Jokerst. Thus, there was substantial evidence from which the trial court could determine the amount Kluesner requested was reasonable. See Little Joe’s,
Finally, Jokerst argues that Kluesner’s claim was defeated by accord and satisfaction, because Kluesner accepted the last check Jokerst sent as final payment for all work. We disagree.
“An accord is an agreement for the settlement of a previously existing claim by a substituted performance. Satisfaction is the performance of the agreement.” Hiblovic v. Cinco-T.C. Inc.,
The check Jokerst sent to Kluesner did not contain any designation that it was being tendered in settlement of Kluesner’s claim for payment of the stand-up curb. The accompanying document listed the check amount as “Final Check Amount Paid.” There was no express communication of the condition that the check be accepted as full satisfaction of Kluesner’s claim for payment for the stand-up curb, nor is there evidence of a prior agreement between Jokerst and Kluesner that this amount would settle their dispute regarding payment for the stand-up curb. Thus, Kluesner’s acceptance of Jokerst’s check did not constitute accord and satisfaction of Kluesner’s claim for payment for the stand-up curb.
In conclusion, there was substantial evidence from which the trial court could find Kluesner proved the elements of quantum meruit. The amount of damages the trial court awarded was the amount outstanding for the stand-up curb listed on Kluesner’s invoices after other undisputed adjustments, and there was substantial evidence from which the trial court could find this a reasonable amount. Kluesner’s acceptance of the last check Jokerst sent was not an accord and satisfaction of Klues-ner’s claim. Point denied.
Point III
Jokerst argues that the trial court’s judgment is inconsistent and ambiguous in that it purports to grant Kluesner relief under both Kluesner’s breach of contract theory and quantum meruit. As we have determined Kluesner was only entitled to recover in quantum meruit, and we affirm only the trial court’s judgment related to Kluesner’s quantum meruit claim, this point needs no further discussion. Point denied as moot.
Point IV
Jokerst argues that the trial court erred in granting Kluesner prejudgment interest because the amount of Kluesner’s claim was in dispute, undetermined, and unliquidated. We disagree.
A trial court is authorized to include prejudgment interest in an award of damages where the amount due was liquidated and demand of payment was made. Section 408.020, RSMo. (Supp. 2012). The fact that an action is in quantum meruit does not render a claim unliq-uidated. Gen. Aggregate Corp. v. LaBrayere,
Jokerst relies on a case in which this Court denied prejudgment interest because the parties had a bona fide dispute over the proper standard to be applied in measuring damages. See St. John’s Bank & Trust Co. v. Intag, Inc.,
Kluesner’s invoice provided Jokerst with a value for the stand-up curb. Jokerst had the ability to determine the fair market value of a stand-up curb in order to liquidate damages at the time Kluesner demanded payment. The trial court made no error of law in awarding prejudgment interest, and the amount awarded is supported by substantial evidence. Point denied.
Conclusion
The trial court erroneously declared and applied the law in concluding Jokerst’s use of Kluesner’s bid and subsequent award of the Cape Project created a contract based on the terms contained in Kluesner’s bid. We reverse this portion of the trial court’s judgment. However, the trial court’s judgment contains findings supported by substantial evidence that Kluesner was entitled to recover on its quantum meruit claim. The damages awarded by the trial court are supported by substantial evidence and reflect the reasonable value of the services Kluesner provided. The trial court did not erroneously apply the law in awarding prejudgment interest. We affirm the trial court’s judgment in favor of Kluesner on its quantum meruit claim, and we affirm the trial court’s award of damages and prejudgment interest.
REVERSED IN PART; AFFIRMED IN PART AND IN RESULT.
Notes
. The parties disputed at trial whether Jokerst informed Kluesner during this initial conversation that Jokerst was seeking a bid for a lump sum contract. The trial court found this conversation did not contain any negotiations or communications of contract terms.
. At trial, the parties disputed whether Jok-erst or the City requested this change, and the trial court made a factual finding that Jokerst requested the change.
. Jokerst had also requested a separate change in the concrete work, for which it voluntarily paid an extra $2,299.70. Jokerst calculated that it owed Kluesner the original total bid price of $104,747.40, plus the extra work of $2,299.70, minus what Jokerst had already paid, $104,695.13, and minus
. This was the amount Kluesner requested in its petition. It is the cost Kluesner listed on its invoices for the stand-up curb, minus the amount of the last check Jokerst had sent to Kluesner and the amount Jokerst had listed as "work billed to finish contract.”
. Despite this, if compelled to discern an underlying contract between the parties, under the factual circumstances here and given the following two principles, we would be hard-pressed to find mutual assent to either a lump sum term or unit price terms. See F.S. Crook, Inc. v. C & R Heating and Serv. Co.,
. Jokerst had previously approved a separate extra payment to Kluesner for a change in concrete work that Jokerst requested, but Kluesner did not submit a change order in that instance and Jokerst did not require one. Jokerst argues this is because the extra work was for Jokerst, and not for the City, thus Jokerst did not need a change order from the City. Jokerst argues it did need one for the stand-up curb, but Jokerst’s obligation to the City does not shed light on whether there was any existing obligation on Kluesner's part.
. Further, even if some requirement for Kluesner to submit a change order existed, under the circumstances here it would arguably have been Jokerst who waived it by orally agreeing to the work. See KC Excavating, 141 S.W.3d at 407.
. Jokerst had filed a counter-petition at trial against the City, arguing that in the event Jokerst was found liable in quantum meruit, the City should indemnify Jokerst as the City retained the benefit of the stand-up curb. The City filed a motion to dismiss, raising various arguments and attaching an affidavit Jokerst signed in August of 2010 affirming that all claims for payment from the City had been paid in full. The trial court granted the City’s motion to dismiss Jokerst’s counter-petition.
