We filed our opinion in this case on October 6, 2021, but subsequently granted the plaintiffs petition for rehearing. Our October 6, 2021 decision is therefore vacated, and this decision replaces it. See Iowa R. App. P. 6.1204(5).
Contracts mean what they say. Here, a party that failed to follow what a contract says in terms of the procedure to change the scope of the contract seeks to avoid the consequences of that failure. We decline to allow such avoidance.
I. Background Facts and Proceedings
In 2016, FDP WTC, LLC (FDP) and Ryan Companies US, Inc. (Ryan) entered into a pair of owner-contractor contracts in which Ryan—the contractor—and FDP—the owner—agreed to terms for the construction of a hotel in Waterloo. The parties entered into the first contract (Courtyard Contract) with a guaranteed maximum price (GMP) of $22,626,869. The parties entered into the second contract (Sitework Contract) with a GMP of $2,501,864.

For purposes of this appeal, the terms of the Courtyard Contract and Sitework Contract are identical.
Ryans senior project executive testified that, before executing the contracts, FDP sought to reduce the contractual scope of the project to reduce the GMP for financing purposes. Nevertheless, Ryans project manager testified that designs issued by FDPs architect did not match assumptions in the contracts, which required modifications in the GMP. To that end, the parties executed a series of change orders to modify the scope and GMP of the project. Ryan also submitted to FDP many more requests for change orders—known as Cost Events (CEs)—for additional work consistent with the architects designs that would increase the GMP. FDP did not sign many of these CEs to increase the GMP. However, the project manager testified Ryan performed the work under the CEs after FDP requested or otherwise orally approved such work.
In 2018, Ryan petitioned to foreclose its mechanics liens against FDP for the project. Ryan later amended its petition to add breach-of-contract claims. FDP answered and counterclaimed with its own breach-of-contract claims.
2
The claims proceeded to a bench trial. The district court found for Ryan on its breach-of-contract and mechanics lien foreclosure claims and denied FDPs breach-of-contract claims. The court entered judgment in Ryans favor for $452,817 on the Courtyard Contract, $224,086 on the Sitework Contract, interest, attorney fees, and costs.
FDP appeals parts of the district courts ruling for Ryan on the parties’ contract claims. FDP argues the court erred in awarding Ryan damages; foreclosing on Ryans mechanics liens; denying FDP credits for reductions in the scope of the parties’ contracts; and awarding Ryan attorney fees, costs, and interest. We partially reverse the district courts finding that FDP breached the parties’ contracts and vacate part of the judgment entered in Ryans favor. We affirm the judgment in Ryans favor for a modified amount as well as for costs and interest. We also affirm the order for foreclosure of Ryans mechanics liens. We vacate the award of attorney fees in Ryans favor and remand for a determination of an appropriate fee award in light of this opinion. Finally, we affirm the finding that FDP did not prove Ryan breached the contracts.
II. Standard of Review
The parties agree the contract claims were tried at law below and our review is for correction of errors at law. See NevadaCare, Inc. v. Dept of Human Servs., 783 N.W.2d 459, 465 (Iowa 2010). “If substantial evidence in the record supports a district courts finding of fact, we are bound by its finding.” Iowa Mortg. Ctr., L.L.C. v. Baccam, 841 N.W.2d 107, 110 (Iowa 2013). “However, a district courts conclusions of law or its application of legal principles do not bind us.”

Id. We review actions to enforce mechanics liens de novo. See Flynn Builders, L.C. v. Lande, 814 N.W.2d 542, 545 (Iowa 2012). “Review of a district courts grant of attorney fees is for an abuse of discretion.” Homeland Energy Sols., LLC v. Retterath, 938 N.W.2d 664, 684 (Iowa 2020).
III. Analysis
A. Ryans Breach-of-Contract Claims
1. Express contract
a. Error preservation
Even though breach of an express contract was one of the primary issues in dispute before the district court, Ryan asserts FDP failed to preserve error on its arguments. As shown below, interpretation of section 6.4 of the contracts is key to the parties’ dispute. Ryan asserts that because FDP did not specifically address section 6.4 before the district court, it preserved no argument on section 6.4 for appeal. See Meier v. Senecaut, 641 N.W.2d 532, 537 (Iowa 2002) (“It is a fundamental doctrine of appellate review that issues must ordinarily be both raised and decided by the district court before we will decide them on appeal.”). However, FDP extensively argued before the district court that Ryan performed work outside the scope of the contracts and failed to obtain proper change orders to modify the scope to include this work. While FDPs trial filings do not address section 6.4, section 6.4 was an issue at trial and the courts ruling squarely addressed its language. Because FDP argued the scope of work and change orders at trial, and the court specifically considered and decided section 6.4 in its ruling, FDPs breach-of-contract arguments are preserved for our review.
b. Elements of breach of contract
To prevail on its breach-of-contract claim, Ryan must show:
(1) the existence of a contract; (2) the terms and conditions of the contract; (3) that [Ryan] has performed all the terms and conditions required under the contract; (4) [FDPs] breach of the contract in some particular way; and (5) that [Ryan] has suffered damages as a result of the breach.
Baccam, 841 N.W.2d at 111 (quoting Molo Oil Co. v. River City Ford Truck Sales, Inc., 578 N.W.2d 222, 224 (Iowa 1998)). FDP challenges the district courts interpretation of the terms of the contracts and whether Ryan performed pursuant to those terms.
The determination of the intent of the parties at the time they entered into the contract is the cardinal rule of contract interpretation. If the principal purpose of the parties is ascertainable from the words and other conduct of the parties in light of all the circumstances, we give those words and conduct great weight when interpreting the contract. When interpreting the meaning of a contract we may also look to extrinsic evidence such as, the situation and relations of the parties, the subject matter of the transaction, preliminary negotiations and statements made therein, usages of trade, and the course of dealing between the parties. However, the most important evidence of the parties’ intentions at the time they entered into the contract is the words of the contract.
NevadaCare, 783 N.W.2d at 466 (quotations and citations omitted).
The parties executed form contracts, modified to their needs, with a GMP. In a GMP contract, generally “the contractor assumes the risk of the costs exceeding a maximum price.” Philip L. Bruner & Patrick J. OConnor, Jr., 2A Bruner & OConnor on Construction Law § 6:109 (Aug. 2021 update). To that end, section 5.2.1 of both contracts states:
The Contract Sum[4] is guaranteed by the Contractor not to exceed [$22,626,869.00 for the Courtyard Contract and $2,501,864.00 for the Sitework Contract], subject to additions and deductions by Change Order as provided in the Contract Documents. Such maximum sum is referred to in the Contract Documents as the Guaranteed Maximum Price. Costs which would cause the Guaranteed Maximum Price to be exceeded shall be paid by the Contractor without reimbursement by the Owner.
(Emphasis added.) Similarly, section 8.1 states the contractors reimbursable costs do not include costs “that would cause the Guaranteed Maximum Price to be exceeded,” unless those costs are “included in Change Orders approved by the Owner.” An attachment to the contracts defines “Change Order” as “a written instrument prepared by the Architect and signed by the Owner, Contractor, and Architect.” The contracts also state they “represent[ ] the entire and integrated agreement between the parties” and “may be amended or modified only by a Modification.[
5
]”
The district court awarded damages above the GMP for work described in CEs. There is no dispute the parties did not sign a written change order to increase the GMP to include some of this additional work. Even so, Ryan asserts—and the court agreed—the contracts provide for another way to increase the GMP in section 6.4:
If no specific provision is made in Article 5 for adjustment of the Contractors Fee in the case of changes in the Work,[6] or if the extent of such changes is such, in the aggregate, that application of the adjustment provisions of Article 5 will cause substantial inequity to the Owner or Contractor, the Contractors Fee shall be equitably adjusted on the same basis that was used to establish the Fee for the original Work, and the Guaranteed Maximum Price shall be adjusted accordingly.
The plain language of section 6.4 shows its purpose is to permit adjustment to the Contractors Fee, which the contracts set at 5% “of the Cost of the Work.” It does not allow for a “catch all” adjustment of the GMP when Ryan fails to obtain a required change order—the claim urged by Ryan and accepted by the district court. Under section 6.4, when the work changes and the contract either does not address changes to the contractors fee
7
or such changes would “cause substantial inequity,” then the contractors fee will “be equitably adjusted.” Section 6.4 allows adjustment of the GMP “accordingly,” i.e., according to the adjustment in the contractors fee. Nothing in section 6.4 allows adjustment of the GMP just because it would seem equitable to do so. Ryans and the district courts interpretation would defeat guarantees elsewhere in the contracts that the owner need not reimburse the contractor for costs above the GMP and would defeat the written-change-order requirements of the contracts. We reject Ryans and the district courts interpretation of section 6.4.
In its brief to us, Ryan emphasizes “the designs and construction documents were not complete when the contracts were executed, and the parties understood and anticipated that the scope of work and GMP were subject to change.” However, section 5.2.5 explicitly requires anticipated changes to be provided in the GMP and any changes in scope “shall be incorporated by Change Order.” Regardless of the extent of changes the parties expected after executing the contracts, the contracts clearly guaranteed FDP would not have to pay more than the GMP without written and signed change orders to increase the GMP. The contracts do not show uncertainty or conditions on these requirements. See, e.g., Bouten Const. Co. v. M & L Land Co., 877 P.2d 928, 934–35 (Idaho Ct. App. 1994) (finding language in the contract showed the initial GMP was preliminary and subject to adjustment as described in the contract); Profl Serv. Indus., Inc. v. J.P. Const., Inc., 491 N.W.2d 351, 353 (Neb. 1992) (finding a contract did not include a GMP because, in part, the contracts total amount explicitly stated “estimated”). Likewise, there is no ambiguity in this provision that would allow us to look at evidence beyond the plain language of the contracts. See Hartig Drug Co. v. Hartig, 602 N.W.2d 794, 797 (Iowa 1999) (allowing extrinsic evidence to help determine intent only if a contract is ambiguous or uncertain). When a contract unambiguously requires a written change order or other procedure to modify the contract, the contractor is generally not allowed to recover for additional work unless the contractor followed this procedure or the owner waived the required procedure.
8
See Ida Grove Roofing & Improvement, Inc. v. City of Storm Lake, 378 N.W.2d 313, 314–15 (Iowa Ct. App. 1985); see also Katsura v. City of San Buenaventura, 65 Cal. Rptr. 3d 762, 763–64 (Cal. App. 2007); Tupelo Redevelopment Agency v. Gray Corp., 972 So. 2d 495, 506–07 (Miss. 2007); Ridley Elec. Co. v. Dormitory Auth. of State, 60 N.Y.S.3d 551, 553–54 (N.Y. App. Div. 2017); Seneca Valley, Inc. v. Caldwell, 808 N.E.2d 422, 426–33 (Ohio Ct. App. 2004). Finding Ryan failed to obtain some of the contractually required change orders to increase the GMP, we reverse that part of the judgment in Ryans favor that was based on work not covered by signed change orders. As FDP did not breach the parties’ contracts with respect to that work, Ryan is not entitled to damages for those amounts.
We only reverse part of the district courts judgment because FDP concedes that it owed a significant amount of the damage award. As previously noted, judgment was entered in favor of Ryan for a total of $676,903 between the two contracts. In its brief, FDP concedes it was not appealing $427,319 of the total damage award. By not appealing that amount, FDP concedes that judgment in that amount was proper. The conceded amount consisted of various retention amounts and charges for work for which signed change orders were provided.
9
Given this concession, we affirm the judgment in Ryans favor for $427,319, plus interest, and costs. We vacate the part of the district courts judgment exceeding that amount.
2. Implied Contracts
To try to recover for work that was not covered by written change orders, Ryan argues the parties had implied-in-fact and implied-in-law contracts that allow it to recover for that work. See Iowa Waste Sys. Inc. v. Buchanan Cnty., 617 N.W.2d 23, 29–31 (Iowa Ct. App. 2000) (discussing implied-in-fact and implied-in-law contracts). The district court rejected the implied-contract theories because “[a]n express contract and an implied contract cannot coexist with respect to the same subject matter.” Legg v. W. Bank, 873 N.W.2d 763, 771 (Iowa 2016) (quoting Chariton Feed & Grain v. Harder, 369 N.W.2d 777, 791 (Iowa 1985)). Ryan asserts its claims are proper for implied contracts because the work at issue was outside the scope of the contracts and thus not covered by the parties’ express contracts. See id. at 771–72 (“[T]here may be a contract implied in law on a point not covered by an express contract ․” (quoting Smith v. Stowell, 125 N.W.2d 795, 800 (Iowa 1964))). However, the work at issue was covered by the parties’ express contracts due to specific language in the contracts requiring valid change orders to add such work to the scope of the project. As a result, we agree with the district court that the recovery Ryan seeks is covered by the parties’ express contracts and no recoveries on implied contract theories are available.
B. Mechanics Liens
FDP argues the foreclosure of Ryans mechanics liens must also be reversed. This argument is based on the premise that Ryan is not entitled to recover on its breach-of-contract claim. Because we find FDP breached the parties’ contracts by failing to pay $427,319 of what it owed Ryan, Ryan established its entitlement to judgment in that amount pursuant to the contracts. Having established its entitlement to judgment on its breach-of-contract claim for $427,319, Iowa Code section 572.2 permitted a mechanics lien to secure that amount. See Rohlin Const. Co., Inc. v. Lakes, Inc., 252 N.W.2d 403, 406 (Iowa 1977) (permitting a mechanics lien for the entire contract price rather than for the reasonable value of services provided). Ryan substantially performed under the contracts. As a result, it has a valid mechanics lien on FDPs property equal to its judgment amount and is entitled to foreclose that lien. See Flynn Builders, L.C., 814 N.W.2d at 545 (holding that a contractor in a mechanics lien foreclosure action is entitled to foreclose a lien for the contract price). We affirm the district courts decision to foreclose Ryan mechanics liens, but for the modified amount stated in this opinion.
C. FDPs Breach-of-Contract Claim
FDP argues Ryan breached the parties’ express contracts by reducing the value of its work without a corresponding reduction in the GMP. FDP asserts Ryan owes credits for these reductions. The district court found the parties agreed to many reductions and additions to the scope of work and, relying on valuations in the record, FDP failed to prove the reductions exceeded the additions so that it was owed credits. The court also noted FDP did not seek credits for amounts it paid to Ryan until Ryan filed its claims here, suggesting FDP itself did not believe it was entitled to credits until Ryan filed its claims. We find substantial evidence to support the district courts finding that FDP failed to prove it was entitled to credits for reductions in work.
D. Attorney Fees, Costs, and Interest
The district court awarded attorney fees, costs, and interest to Ryan as the prevailing party. Regarding the mechanics lien foreclosure claims, Iowa Code section 572.32(1) allows “a prevailing plaintiff” to recover “reasonable attorney fees.” Regarding the breach-of-contract claims, section 15.2 of the contracts states:
In the event that any payment by [FDP] to [Ryan] is not paid when due, [FDP] shall pay interest on said unpaid amount ․ [FDP] shall pay to [Ryan] all costs reasonably incurred by [Ryan] in the collection of amounts payable to Contractor hereunder, including reasonable attorneys fees.
Because Ryan prevailed on its mechanics lien foreclosure claim and its breach-of-contract claim, Ryan is entitled to recover attorney fees by statute and contract. However, we recognize that the district courts award of attorney fees was based on its ruling that Ryan succeeded on all of its claims. As this opinion modifies the district courts ruling to vacate part of Ryans judgment, we believe reconsideration of the attorney fee award is appropriate to take into account Ryans only partial success. As a result, we vacate the attorney fee award and remand to the district court to determine an appropriate attorney fee award in light of the partial success and partial lack of success by Ryan in this suit.
IV. Conclusion
Because Ryan sought to increase costs of the work beyond the GMP without obtaining valid change orders for some of its work, we reverse that part of the district courts ruling that awarded Ryan damages for the unapproved work. Given FDPs concessions, Ryans judgment for damages is reduced to $427,319. The part of the district courts judgment that exceeded $427,319 is vacated. Ryan shall also have judgment for interest and court costs as the prevailing party. The judgment in Ryans favor for attorney fees is vacated, and the case is remanded to the district court for determination of an appropriate attorney fee award under the mechanics lien statute and the parties’ contracts in light of Ryans partial success. We affirm the district courts decision to foreclose Ryan mechanics liens, but for a modified amount consistent with this opinion, the final amount of which will be determined by the district court on remand. Costs on appeal are assessed two-thirds against Ryan and one-third against FDP.

FDP notes the district court largely adopted Ryans proposed findings of fact and conclusions of law on the breach-of-contract and mechanics lien foreclosure claims, and thus FDP asks us to scrutinize the courts ruling. See NevadaCare, 783 N.W.2d at 465 (“[W]here a district court adopts a prevailing counsels proposed findings of fact and conclusions of law verbatim, we must scrutinize the record more carefully when conducting our appellate review.”). At the courts invitation after trial, both parties submitted proposed findings of fact and conclusions of law. On our review of the record, the court clearly based its ruling on Ryans proposal, though the court also edited Ryans language and added findings including explicit credibility findings. While the facts on appeal are mostly undisputed and the courts conclusions of law are not binding, we are mindful the court adopted much of Ryans proposal, and we will scrutinize the courts ruling accordingly.
