This is аn appeal from a decision of the Armed Services Board of Contract Appeals (board) denying the claims brought by Community Heating and Plumbing Co., Inc. (Community), against the Secretary of the United States Navy (Navy). 1 The claims arose out of a contract to remove and replace the condensate and steam system located at the Mаrine Corps Air Station, Cherry Point, North Carolina. Community seeks compensation for; 1) the costs associated with the installation of conduit sleeves in existing manholes; and, 2) the costs which arose from delays experienced by the project. 2 We affirm the decision of the board.
The Conduit Sleeve Claim
On May 18, 1982, Community submitted a bid in response to the Navy’s Invitation for Bids. On May 19, Navy Contract Specialist Rosalind D. Rogers reрlied by mail informing Community that although it was the apparent low bidder, its bid appeared “somewhat out of line” as compared to the Navy’s estimate and the other bids received. In fact, Community’s estimate for the project was 14% below the Navy estimate and 5% below the second lowest bid received. Accordingly, Ms. Roger’s letter instructed Community to check its proposal and confirm its bid price in writing. In addition, Navy officials decided that if the bid were confirmed, Community should also be required to meet with the Navy officials to reverify the project’s scope. On June 1,1982, Community confirmed its bid, and on June 3 a bid confirmation meeting was held at the Navy’s offices. Those present at the meeting included Mr. Levy for Community and Mr. Mаnger (LANT-DIV Engineer), Mr. Hiteshaw (the drafter of the project drawings), and Ms. Rogers for the Navy. 3 The only evidence in the record regarding the discussions which took place at the meeting was the testimony of those in attendance and a memorandum written by Ms. Rogers the following day.
On June 4, 1982, the day after the meeting, Mr. Levy wrote a letter to the Navy *1578 referencing the meeting and stating in part:
The items listed below wеre discussed and approved during our June 3, 1982 conference.
3. The conduit sleeves shown on Sheet M-5 in the lower righthand corner are for the new manholes only for both condensate and steam.
(Emphasis added.)
The Navy responded to Community’s June 4 communication with a letter dated June 21, 1982. That letter made no express objection to Community’s contract interpretation regarding the conduit sleeves, but it did state in part:
The meeting rеferred to in your letter was held as part of the bid confirmation process in order to insure that you had considered all components of the job in preparing your bid. Contract awards on formally advertised procurements must be made in strict accordance with the terms of the Invitation for Bids.
It is requested that you verify in writing the correctness of yоur bid in accordance with the Invitation for Bids.
On June 30, 1982, the bid was confirmed in writing, and on July 15, 1982, the contract, No. N62470-81-C-1345, was awarded to Community.
After the contract was awarded, the Navy directed Community to furnish conduit sleeves in new and existing manholes “where needed.” Community then brought a claim for additional compensation, ASBGA No. 38167, arguing that the contract required installation of conduit sleeves at new manholes only. Upon consideration of the evidence, the board ruled in favor of the Navy in a final decision dated February 24, 1992. The board held that the contract was unambiguous since there was “no way” the contract could be construed in the manner advocated by Community. Community now appeals.
Standard of Review
Under 41 U.S.C. § 609(b) (1988), the decisiоn of the board on any question of law is not final or conclusive, but the decision on any question of fact “shall be final and conclusive and shall not be set aside unless the decision is fraudulent, or arbitrary, or capricious or so grossly erroneous as to necessarily imply bad faith, or if such decision is not supported by substantial evidence.”
See Triax-Pacific v. Stone,
Community argues that the contract contained latent ambiguity and, because the June 4 letter gave notice of Community’s contract interpretation, the Navy is bound to that interpretation by its failure to object.
Lykes-Youngstown Corp. v. United States,
Community asserts that the contract, as it pertains to the conduit sleeves, is ambiguous. It contests the Navy’s reading of the contract, which was adopted by the board, and argues in favor of an alternative contract interpretation based upon its own reading of the contract language, specifications and drawings. However, contracts are not necessarily rendered ambiguous by the mere fact that the parties disagree as to the meaning of their provisions.
Brunswick Corp. v. United States,
Here, Community’s contract interpretation, based on its reading of the contract drawings and specifications, is not reasonable. First, there is substantial evidence in the drawings to support the board’s finding that conduit sleeves are required in new and existing manholes. 4 Second, the M-6 project drawings are entitled “Typical Detail Showing Penetration of Exist. Manholes or Bldg. Pit Wall for Condensate Line”. (Emphasis added.) Finally, other bidders interpreted the drawings to mean that the conduit sleeves are required in new and existing manholes. 5
In addition, the board held that the contract was unambiguous. Contract ambiguity is a question of law,
Newsom v. United States,
Assuming the contract were ambiguous, Community’s claim would still fail because the contract ambiguity is patent and not latent.
6
The determination of whether an ambiguity is patent is not a “yes-no proposition.”
Newsom,
If a contract contains a patent ambiguity, the contractor is under a duty to inquire and must seek clarification of the proper contract interpretation.
Interstate Gen. Gov’t Contractors, Inc., v. Stone,
In addition, where a discrepancy exists in the contract drawings, as Community here alleges, a contractor may be required to seek clarification.
Jefferson Constr. Co. v. United States,
However, it is not enough under the duty to inquire that a contractor merely make an initial inquiry.
Beacon Constr. Co. v. United States,
This holding was reiterated in Southside Plumbing Co., ASBCA No. 8120, 64 BCA (CCH) If 4314 at 20,860. In that case, a contractor became aware of an ambiguity prior to bidding, sought and received an addendum that was expected to furnish clarification and later realized that the addendum failed to resolve the ambiguity. Without seeking further clarification, the contractor bid on the basis of its own interpretation, which, under the circumstances, was more favorable to the contractor. The board held that the contractor had not met its burden under the duty to inquire. “Here, the appellant not only recognized the ambiguity but made inquiry. This circumstance, in our opinion, brings the cаse within the principle in Construction Service Company, that the inquiry should have been pursued to clarification.” Id. at 20,861 (citation omitted).
The Navy’s response to the June 4 letter expressly failed to address the issue of the conduit sleeves and thus provided a strong indication to Community that confusion still existed between the parties. Community was therefore obligated to request further clarification regarding thе proper installation of the conduit sleeves. While it troubles this court that the Navy did not directly and timely object to Community’s contract interpretation, Community nevertheless failed to satisfy its own obligations under the duty to inquire and thus acted at its own risk when it proceeded to perform on the contract.
In addition, while not a direct response to thе June 4 letter, the Navy’s reply was sufficient to indicate that the Navy did not acquiesce to Community’s alternative contract interpretation.

Claims Arising From Work Delays
Community asserts that a 474-day wоrk delay caused by the Navy resulted in an *1581 unanticipated increase in the total cost of completing the contract. Accordingly, Community seeks to recover alleged additional costs associated with contractor-owned equipment (ASBCA No. 37981), home office overhead (ASBCA No. 40151), field office overhead (ASBCA No. 38467), overtime (ASBCA No. 38166), lost labor productivity (ASBCA No. 40151) and express profit (ASBCA No. 38168). The board found that an accord and satisfaction had occurred as a result of Community’s execution of various contract modifications and therefore denied Community’s entitlement to all delay and impact costs. The board also rejected each of these claims individually.
Dischargе of a claim by accord and satisfaction occurs when some performance different from that which was claimed as due is rendered and such substituted performance is accepted by the claimant as full satisfaction of his claim.
Brock & Blevins Co. v. United States,
On February 25, 1988, Community submitted to the Navy a claim for $390,506 to recover the cost of contractor-owned equipment during an 8-month time extension of the contract. A contractor may recover the cost of contractor-owned equipment incurred over an extended contract period when the government requires the use of that equipment beyond the original contract period and thereby deprives the contractor of its useful value.
Nolan Bros. v. United States,
This court reviewed the two methods of recovering home office overhead in
C.B.C. Enterprises, Inc. v. United States,
*1582
In the present case, Community’s claim for home office costs arises out of contract performance involving continuous original and additional changes work rather than a suspension оr hiatus in performance which would affect direct costs. There was no evidence that the contract changes resulted in a delay in performance which required Community to stand by idly and suspend its work. In addition, Community was paid a 27% home office overhead markup to compensate for change order work. Accordingly, Community’s claim to recover extended home office overhead costs by any method is rejected.
Remaining Claims
Finally, Community seeks to recover field overhead costs for the period between September 15, 1985 and October 31, 1985; lost labor productivity costs caused by Navy acts and omissions; the overtime wages it paid to its work force for performing extra work; аnd additional profit on contract modifications associated with differing site conditions. The opinion of the board denying Community recovery on these claims, for the reasons and facts there stated, is not arbitrary or capricious, is supported by substantial evidence, and is therefore affirmed.
Conclusion
For the aforementioned reasons, the dеcision of the board is
AFFIRMED.
Notes
. Community Heating & Plumbing Co., ASBCA Nos. 37981, 38166, 38167, 38168, 38467, 40151, 92-2 BCA (CCH) ¶ 24,870 at 124,051.
. In this combined appeal, Community seeks the following work delay costs: extended contractor-owned equipment (ASBCA No. 37981); extended home office overhead (ASBCA No. 40151); extended field office overhead (ASBCA No. 38467); overtime (ASBCA No. 38166); lost labor productivity (ASBCA No. 40151); and profit in excess of the 6% allowed by the Navy on contrаct modifications (ASBCA No. 38168). Also claimed was an equitable adjustment for placing conduit sleeves on existing manholes. (ASBCA No. 38167.)
.Also present at the meeting were Mr. Harrison and Mr. Butt representing the Navy. The latter was the writer of the specifications.
. For example, the Sheet M-6 drawings indicate that the existing manhole wall must be patched with concrete. However, if conduit sleeves were required in new manholes only, the concrete around existing manholes would not need to be broken and patched up to install the sleeve.
. This is evidenced by Community’s bid estimate which was 5% below that of the second lowest bidder and 14% below the Navy’s estimate.
. Even if the ambiguity were latent, appellant’s claim would still fail. A contractor's interpretation of a latent ambiguity will only be adopted if it is found to be reasonable.
Froeschle Sons, Inc. v. United States,
. Specifically, the evidence shows that the Navy administered, reviewed, and negotiated Community’s claims on its merits prior to and after execution of the subject contract negotiations and waited more than two and one-half years to first raise the defense of accord and satisfaction.
