FACTS
Lazovitz, Inc. (Lazovitz) as general contractor entered into three cost-plus construction contracts covering three different projects: Florida Club Care Center, Florida Club Apartments, and Grammercy Park Nursing Care Center. On paper, each project is owned by a limited рartnership registered in Florida that carries the name of the project; however, the people behind all three projects are the same. In this opinion, the term “owner” refers to the common interest behind the three projects. To accomplish certain plastering and drywall work, Lazovitz entered into three subcontracts with Saxon Construction, Inc. (Saxon) for work on each of the three projects. Each subcontract was project specific. Insofar as they are at issue in this appeal, the terms of the three general сontracts are the same and the terms of the three subcontracts are the same. On each of the three projects, Saxon allegedly breached its respective subcontract by failing to complete work as prescribed in the architect’s plans. Lazovitz dischаrged Saxon and hired a replacement subcontractor to complete the work. To ensure that the substitute work was accomplished in a timely fashion, the owner “advanced” La-zovitz the money needed to pay the substi *590 tute subcontractor for the repairs. Lazo-vitz and thе owner executed separate supplemental letter agreements for each of the three projects to govern their respective obligations regarding the advance. The three agreements substantively are the same.
Pursuant to its understanding of its obligation under the supplemental agreements, Lazovitz filed a nine count complaint against Saxon for breach of contract and trespass on each of the three construction projects; Lazovitz alleged that Saxon breached the contract by failing to complete performance. Saxon counterclaimed on each of the subcontracts with Lazovitz for the amount due alleging substantial performance of the subcontract. Lazovitz answered that Saxon had breached the contract and claimed a set-off as an affirmative defense to Saxon’s counterclaim asserting the same damages alleged in its complaint. During discovery, Saxon obtained a copy of the supplemental agreement governing the Florida Club Care project; however, it did not obtain the supplemental agreements covering the other two projects. Saxon moved for summary judgment with respect to the counts concerning the Florida Club Care project, claiming that the supplemental agreement showed that Lazovitz had suffered no damages. On June 10, 1987, the district court granted Saxon’s motion. The case went to trial on November 2, 1987; in the interim, however, Saxon obtained copies of the remaining two supplemental agreements. At the start of the trial, Saxon made an ore terms motion for summary judgment on the counts concerning the remaining two projects. 1 The district court granted the motion and the trial proceeded on Saxon’s counterclaim for the balance due under the contract with Lazovitz claiming breach of contract and set-off.
In deciding the motions for summary judgment, the district court considered the underlying cost-plus contract and the supplemental аgreement and concluded that Lazovitz had a conditional obligation to repay the owner. Since the owner had paid all the costs, including the additional amount necessary to effect the repairs, and had paid the agreed upon “plus,” the district court reasonеd that Lazovitz had suffered no damage. The court also reasoned that since Lazovitz’s repayment obligation was conditional and since the owner had made no demand for repayment, the possibility that Lazovitz might at sometime in the future be held liable for the advanced funds was tоo speculative to give rise to any compensable damage. The court concluded that without any damages, Lazovitz did not have a cause of action.
At the trial on Saxon’s counterclaim, the court awarded Saxon the contract price minus certain set-оffs. 2 The district court disallowed Lazovitz’s claims for breach of contract and setoff to obtain substitute performance on the same theory upon which it had relied to grant summary judgment. After trial, Saxon moved to tax costs against Lazovitz; the district court granted the motion concluding that Sаxon was the prevailing party.
The gravamen of appellant’s claim is that the district court erred by interpreting the written supplemental agreement as a conditional obligation. Lazovitz maintains that the agreement is clear on its face that it is obligated to return the money advanced. In support of its contention, Lazovitz submitted the affidavit of the owner’s general partner who asserted that the money advanced to Lazovitz was to be returned. Saxon offered nothing to rebut the affidavit. Appellant also claims that even if the document is not clear on its face, the affidavit creates a genuine issue of material fact which precludes summary judgment. *591 Appellee asserts that since the district court heard appellant’s breach of contract and set-off claim at trial, the issue of whether the court properly grаnted summary judgment is moot.
DISCUSSION
A. Summary Judgment Was Not Appropriate.
The district court concluded that La-zovitz could not sue Saxon because Lazo-vitz had suffered no damages. In granting summary judgment, the district court relied on a line of Florida construction cases which hold that the non-breaching party “must show actual expenditures oсcasioned by the breach.”
Tuttle/White Constructors, Inc. v. Montgomery Elevator Co.,
Additionally, the district court misapprehended the function of a cost-plus contract. Cost-plus contracts are often not competitively bid and are frequently used when the owner lacks the special expertise needed to select competent subcontractors and to coordinate the project.
Jones v. J.H. Hiser Constr. Co.,
Thus, in the typical cost-plus contract, it is the general contractor who has both the expertise and the obligation to litigate, if necessary, issues of non-complying performance and breach. Nothing distinguishes the cost-plus contracts in this case from the typical case.
Our inquiry does not end there as the owner and the contractor executed supplemental agreements. However, contrary to the district court, we conclude that the supplemental agreements do not alter the substance of the principal contracts and do not create a conditiоnal obligation to repay. In the supplemental agreements, Lazovitz acknowledges full responsibility for Saxon’s breach, and the excess cost paid by the owner is referred to as an “advance.” We recognize that the reimbursement clause of each supplemеntal agreement creates some ambiguity. The meaning of contract terms is an issue of law and therefore is a matter for the court to decide; nevertheless, the meaning of ambiguous terms may be proved by extrinsic evidence.
Reed v. Florida Dept. of Transportation,
B. Saxon’s Counterclaim.
Saxon maintains that since the terms of the supplemental agreement were fully litigated in the bench trial of Saxon’s counterclaim and Lazovitz’s set-off defense, Lazovitz’s objection to the district court’s disposal of its complaint on summary judgment is moot. However, it appears that the district court simply adhered to its legal interpretation of the supplemental agreements when it decided the case at trial. The district court declined to allow Lazovitz to raise its breach of contract defense because Lazovitz could claim no set-off. We conclude that this was error and that the district court also erred by allowing Saxon to recover on the contract. Saxon may recover on the contract only if it substantially performed under the contract.
Beeson v. Sartori,
CONCLUSION
For the foregoing reasons, the judgment of the distriсt court is VACATED and the case REMANDED for new proceedings consistent with this opinion.
Notes
. The complaint included two other counts which alleged that Saxon had failed to submit to Lazovitz time sheets and other such paperwork required by the FHA pursuant to the terms of the FHA loan used to finance the рrojects. The district court required Saxon to submit the necessary papers before it would proceed to trial. These counts were then dismissed.
. These set-offs consisted primarily of payments made by Lazovitz to subcontractors and materi-almen hired by Saxon who Saxon failed to pay. Saxon did not dispute these, and apparently the owner had not reimbursed Lazovitz for these costs.
