U.S. GOVERNMENT PRINTING OFFICE BOARD OF CONTRACT APPEALS WASHINGTON, DC 20401 STUART M. FOSS Administrative Judge Appeal of RD PRINTING ASSOCIATES, INC. Docket No. GPO BCA 02-92 Jacket No. 612-032 Program 1284-S December 16, 1992 DECISION AND ORDER This appeal, timely filed by RD Printing Associates, Inc., 1865 New Highway, Farmingdale, New York 11735 (hereinafter Appellant or Contractor), is from the final decision of Contracting Officer Frank Dillon of the U.S. Government Printing Office's (hereinafter Respondent or GPO or Government) New York Regional Printing and Procurement Office (NYRPPO), 201 Varick Street, Room 709, Seventh Floor, New York City, New York 10014, dated January 6, 1992, rejecting the Appellant's interpretation of a pricing provision relating to charges for collating fold-ins under its contract identified as Jacket No. 612-032, Program 1284- S (R4 File, Tab E). 1/ For the reasons which follow, the decision of the Contracting Officer is hereby REVERSED. 2/ FINDINGS OF FACT 3/ 1. On January 29, 1991, the NYRPPO issued an Invitation for Bids (IFB) soliciting bids for Program 1284-S, a contract covering the production of fold-ins for the Department of the Navy (Navy), in Brooklyn, New York (R4 File, Tab A, p. 1). 4/ The successful bidder was to receive a "Single Award" term contract, for the period beginning February 1991 (the date of the award) to January 31, 1992 (R4 File, Tab A, p. 1). 2. The work covered by Program 1284-S was ". . . the production of fold-ins requiring such operations as copy pickup, film making, printing, binding, packing, labeling and distribution" (R4 File, Tab A, p. 10). The following IFB specifications are particularly pertinent to this appeal: REQUIREMENTS: This is a requirements contract for the items and for the period specified herein. Shipment/delivery of items or performance of work shall be made only as authorized by orders issued in accordance with the clause entitled "Ordering." The quantities of items specified herein are estimates only, and are not purchased hereby. Except as may be otherwise provided in this contract, if the Government's requirements for the items set forth herein do not result in orders in the amounts or quantities described as "estimated", it shall not constitute the basis for an equitable price adjustment under this contract (R4 File, Tab A, p. 6). [Emphasis added.] * * * * * * * * * * FREQUENCY OF ORDERS: (Based on last [years'] contract) approximately 83 orders per year (R4 File, Tab A, p. 10). NUMBER OF FOLD-INS PER ORDER: Approximately 1 to 134 fold-ins per order (R4 File, Tab A, p. 10). QUANTITY: Approximately 35 to 600 copies of each fold-in, with an average of 170 copies per fold-in per order (R4 File, Tab A, p. 10). TRIM SIZES: 11" x various lengths up to 58" (R4 File, Tab A, p. 10). * * * * * * * * * * PRINTING: Print face only or face and back in black ink (R4 File, Tab A, p. 10). MARGINS: Margins will be as indicated on the print order or furnished copy. Blank apron of 8 1/2 x 11" required on bind side of all foldouts unless waived in the print order (R4 File, Tab A, p. 10). BINDING: Fold to 8 1/2 x 11" with parallel folds, unless otherwise specified folio numbers must be visible after folding. Band each fold-in leaf/page in suitable units with a strip of heavy kraft paper, not less than 3" in width, around the short dimension or shrink-film wrap, if specified. Collating into sets will be required 25% of the time-pagination sheet will be provided (R4 File, Tab A, p. 11). * * * * * * * * * * SECTION 3.-DETERMINATION OF AWARD The Government will determine the lowest bid by applying the prices offered in the "Schedule of Prices" to the following units of production which are the estimated requirements to produce 12 months orders under this contract. . . .

When drilling each ply of a fold-in will be counted as a single leaf. (d) Collating fold-ins......per 100 leaves.......$___________ (R4 File, Tab A, p. 17). 5/ [Emphasis added.] 3. The Appellant, a former contractor on Program 1284-S, submitted a bid in response to the IFB and was awarded the contract for 1991-1992 (R4 File, Tab A, Appendix). 4. Program 1284-S print orders were issued by the Navy. 6/ After the Appellant completed the work, under the terms of the contract it submitted its vouchers for payment to the Respondent's Central Office Financial Management Service (FMS) (R4 File, Tab A, p. 6). During December 1991, the FMS' Voucher Examination Section reviewed two of the Appellant's invoices, and determined that the Contractor's billing method for collating under the contract- specifically Section 4, Part IV, ¶ (d)-was erroneous (R4 File, Tab B). The comparison between the Appellant's billing method and the one used by the FMS shows the following: Quantity Cost Quantity Cost Print Order Billed Billed Per FMS Per FMS 40145 17,220 $688.80 3,690 $147.60 40146 12,555 $502.20 2,835 $113.40 Accordingly, on December 6, 1991, the FMS notified the Appellant of the corrections it was making to the vouchers, and told the Contractor that the appropriate reductions would be taken from its invoices; i.e., $541.20 from Print Order 40145 and $388.80 from Print Order 40146 (R4 File, Tab B). 5. On December 9, 1991, the Appellant wrote to the FMS objecting to the deductions in the vouchers, arguing instead that in calculating its bill for collating it had applied Section 4, Part IV, ¶ (d) correctly (R4 File, Tab B). The Contractor's position was based on its view that "[t]he item in question is determined by the number of [f]oldout units or [l]eafs [sic] . . . times the quantity . . . times [$] 4.00 per hundred leafs [sic]" (R4 File, Tab B).7/ According to the Appellant's arithmetic, collating under Print Order 40145 was properly billed as $688.80-42 (units) times 410 (run) equals 17,200 (quantity) times $4.00 (per hundred leaves) (R4 File, Tab B). Similarly, Print Order 40146 was properly figured at $502.20-31 (units) times 405 (run) equals 12,555 (quantity) times $4.00 (per hundred leaves) (R4 File, Tab B). Therefore, the Appellant asked the FMS to make the necessary adjustments and pay the invoices in full (R4 File, Tab B). 6. It seems that the Appellant also telephoned the Contracting Officer about this billing dispute at the same time that it wrote to the FMS. 8/ R.Brf., Dillon Declaration, ¶ 4. The Appellant followed this initial contact with a letter, dated December 18, 1991, in which it reaffirmed its position that billing for collating under Program 1284-S is properly based on the "leaf/page" method of calculation (R4 File, Tab C). 7. In support of its position, the Appellant expressly referred to Section 4, Part II of the specifications, which tells the Contractor that the payment for all paper supplied under the contract will be based on the net number of leaves furnished for the product(s) ordered (R4 File, Tab A, p. 16). The Appellant specifically relied on the second paragraph of Part II, which computes the net number of leaves for fold-ins on the basis of one page-size leaf for each "fold-in unit," and determines the number of units in a particular fold-in by dividing its trim size (expressed in square inches) by 94 square inches (R4 File, Tab A, p. 16). 9/ As interpreted by the Appellant, that contract provision meant that "[w]hen determining the number of units or leaves to be collated, or for that matter, stock used, running time, etc., you would take the number of leaves, (units) times the quantity or run and then multiply that number by the dollar charge per 100 leaves" (R4 File, Tab C). 10/ Finally, the Appellant informed the Contracting Officer that, as suggested by him, the Contractor had contacted the Navy and was told by Michael O. Blanks, Assistant Director of the Navy's Publishing and Printing Service Detachment Office, that the customer-agency agreed with this interpretation (R4 File, Tab C). See also, Complaint, ¶ 11. 11/ 8. In response to the Contractor's arguments concerning the payment reductions to its vouchers, the Contracting Officer reviewed the two disputed invoices, compared them to random billings from the Program 1284-S contractor for the previous year-Braceland Brothers-and concluded that the Appellant's billing method was incorrect (R4 File, Tab D). 9. On January 6, 1992, the Contracting Officer wrote a letter to the Appellant rejecting its claim with respect to the two disputed invoices as inconsistent with the contract specification for billing fold-ins (R4 File, Tab E). The Contracting Officer distinguished the examples given by the Appellant as relating to the definition of fold-in units when calculating the prices for other production processes and materials-e.g., printing, film, paper, etc.-not collating (R4 File, Tab E). 12/ As explained in his letter, the Contracting Officer believed that with respect to collating: The contract calls for collation of [fold-ins-not [fold-in] units. And it calls for a price per 100 leaves. A reasonable interpretation of [fold-ins] per 100 leaves would be the actual [fold-in], regardless of size, being one leave [sic] for the purpose of collation. This interpretation is consistent with all of the GPO contracts and must be used in the billing procedure. . . . Estimates of the cost of doing collation, using your interpretation, show a marked increase in the cost to the Government for collation over and above what would be considered a reasonable cost. 13/ (R4 File, Tab E). 10. Although not expressly so designated, the Contracting Officer's letter of January 6, 1992, was clearly his "final decision" in the matter, since the Appellant was informed of its appeal rights under GPO Contract Terms (R4 File, Tab E). GPO Contract Terms, Contract Clauses, ¶ 5 (Disputes). Therefore, by letter dated January 10, 1992, the Appellant filed its appeal in this dispute with the Board. 14/ ISSUES PRESENTED 1. Do the terms of the Program 1284-S contract in dispute, taken as a whole, support the Contracting Officer's interpretation that the Appellant is only entitled to be paid for collating fold-ins on the basis of the total number of fold-ins, not fold-in units? 2. Even if the Contracting Officer is correct in asserting that the price for collating is to be based on the total number of fold-ins, not fold-in units, does the Appellant's interpretation of the contract also fall within the "zone of reasonableness" so that, in effect, the contract language is ambiguous? 3. Assuming the Contracting Officer's interpretation of the contract is the only correct one, is the Respondent nonetheless estopped from recovering the overpayments made to the Appellant for collating fold-ins because it had paid the Contractor on the basis of fold-in units under an identical pricing specification contained in the 1988-89 Program 1284-S contract? CONCLUSIONS 15/ This case is before the Board because the parties have drawn different meanings from the terms of the Program 1284-S contract. The Board's task, therefore, is simple-it must determine which of the two conflicting interpretations is correct, or whether both readings may be reasonably derived from the contract specifications; i.e., whether the contract is ambiguous? RPTC, p. 3. The issue of whether or not the provision of the contract relating to charges for collating is ambiguous is a question of law, General Business Forms, Inc., GPO BCA 2-84 (December 3, 1985), Sl. op. at 16 (citing, John C. Grimberg Company v. United States, 7 Ct.Cl. 452 (1985)), and thus any decision by this Board concerning such a matter is reviewable by the Courts under the Wunderlich Act, 41 U.S.C. §§ 321, 322. Fry Communications, Inc./ InfoConversion Joint Venture v. United States, 22 Cl.Ct. 497, 501, fn. 6 (1991); General Business Forms, Inc., supra, Sl. op. at 16. Accordingly, since the focus of inquiry in this case is confined to the contract itself, certain legal principles should be kept in mind at the outset. When the parties confront the Board with two different interpretations of the same contract language they raise the possibility that the specifications may be ambiguous. R.C. Swanson Printing and Typesetting Company, supra, Sl. op. at 41. Contractual language is ambiguous if it will sustain more than one reasonable interpretation. 16/ Fry Communications, Inc./ InfoConversion Joint Venture, GPO BCA 9-85 (August 5, 1991), Sl. op. at 9 (Decision on Remand); General Business Forms, Inc., supra, Sl. op. at 16. See also, Fry Communications, Inc./InfoConversion Joint Venture v. United States, 22 Cl.Ct. 497, 503 (1991) (citing, Edward R. Marden Corporation v. United States, 803 F.2d 701, 705 (Fed. Cir. 1986); Sun Shipbuilding & Drydock Co. v. United States, 183 Ct.Cl. 358, 372 (1968)). In analyzing disputed contract language, the courts and contract appeals boards place themselves in the shoes of a reasonably prudent contractor; i.e., the language of the contract must be given that meaning which a reasonably intelligent contractor acquainted with the circumstances surrounding the contract would derive. General Business Forms, Inc., supra, Sl. op. at 18 (citing, Salem Engineering and Construction Corporation v. United States, 2 Cl.Ct. 803, 806 (1983)). See also, Norcoast Constructors, Inc. v. United States, 448 F.2d 1400, 1404, 196 Ct.Cl. 1, 9 (1971); Firestone Tire and Rubber Company v. United States, 444 F.2d 547, 551, 195 Ct.Cl. 21, 30 (1971). A dispute over contract language is not resolved simply by a decision that an ambiguity exists-it is also necessary to determine whether the ambiguity is latent or patent. Courts will find a latent ambiguity where the disputed language, without more, admits of two different reasonable interpretations. Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 503 (citing, Edward R. Marden Corporation v. United States, supra, 803 F.2d at 705); R.C. Swanson Printing and Typesetting Company, supra, Sl. op. at 41, fn. 22. In such cases, the doctrine of contra proferentem applies and the dispute language will be construed against the drafter, Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 503 (citing, William F. Klingensmith, Inc. v. United States, 205 Ct.Cl. 651, 657 (1974)); R.C. Swanson Printing and Typesetting Company, supra, Sl. op. at 41, fn. 22, if the non-drafter can show that he/she relied on the alternative reasonable interpretation in submitting his/her bid. 17/ Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 510 (citing, Fruin-Colon Corporation v. United States, 912 F.2d 1426, 1430 (Fed. Cir. 1990)); Lear Siegler Management Services v. United States, 867 F.2d 600, 603 (Fed. Cir. 1989). On the other hand, a patent ambiguity would exist if the contract language contained a gross discrepancy, an obvious error in drafting, or a glaring gap, as seen through the eyes of a "reasonable man" on an ad hoc basis. Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 504 (citing, Max Drill, Inc. v. United States, 192 Ct.Cl. 608, 626 (1970); WPC Enterprises, Inc. v. United States, 163 Ct.Cl. 1, 6 (1963)); General Business Forms, Inc., supra, Sl. op. at 17 (citing, Enrico Roman, Inc. v. United States, 2 Cl.Ct. 104, 106 (1983)). Where there are such discrepancies, errors, or gaps, the contractor has an affirmative obligation to ask the contracting officer to clarify the true meaning of the contract language before submitting its bid. Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 504 (citing, Newsom v. United States, 230 Ct.Cl. 301, 303 (1982)); Enrico Roman, Inc. v. United States, supra, 2 Cl.Ct. at 106; S.O.G. of Arkansas v. United States, 546 F.2d 367, 212 Ct.Cl. 125 (1976); Beacon Construction v. United States, 314 F.2d 501 (Ct.Cl. 1963). The patent ambiguity doctrine is aimed at avoiding costly post-award litigation, as well as protecting the integrity of the bidding process by ensuring that all offerors bid on the same specifications. Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 504 (citing, S.O.G. of Arkansas v. United States, supra, 212 Ct.Cl. at 125; Newsom v. United States, supra, 230 Ct.Cl. at 303); General Business Forms, Inc., supra, Sl. op. at 17 (citing, Enrico Roman, Inc. v. United States, supra, 2 Cl.Ct. at 107). The rules concerning ambiguous contract language come into play only if the meaning of the disputed terms are not susceptible to interpretation through the usual rules of contract construction. R.C. Swanson Printing and Typesetting Company, supra, Sl. op. at 42. The most basic principle of contract construction is that the document should be interpreted as a whole. 18/ Hol-Gar Manufacturing Corporation v. United States, 351 F.2d 972, 975, 169 Ct.Cl. 384, 388 (1965); General Business Forms, Inc., supra, Sl. op. at 16; Restatement (Second) Contracts, § 202(2) (1981). Hence, all provisions of a contract should be given effect and no provision is to be rendered meaningless. Fortec Constructors v. United States, 760 F.2d 1288, 1292 (Fed. Cir. 1985); Jamsar, Inc. v. United States, 442 F.2d 930 (Ct.Cl. 1971); Grace Industries, Inc., ASBCA No. 33553, 87-3 BCA ¶ 20,171; General Business Forms, Inc., supra, Sl. op. at 16 (citing, Raytheon Company v. United States, 2 Cl.Ct. 763 (1983)). In other words, a contract should be interpreted in a manner which gives meaning to all of its parts and in such a fashion that the provisions do not conflict with each other, if this is reasonably possible. B. D. Click Company v. United States, 614 F.2d 748 (Ct.Cl. 1980). It is unnecessary to set forth in detail the rules of contract construction which apply when interpreting an agreement. 19/ One rule of construction, however, may have some particular relevance to this dispute. In that regard, it is well-accepted that a prior course of dealing between the parties in earlier contracts can beused to show the meaning of the current contract. 20/ Gresham & Company, Inc. v. United States, 470 F.2d 542, 200 Ct.Cl. 97 (1972); L.W. Foster Sportswear Company v. United States, 405 F.2d 1285, 186 Ct.Cl. 499 (1969); Coastal States Petroleum Company, ASBCA No. 31059, 88-1 BCA ¶ 20,468. Applying these principles to the facts in the record, the Board reaches the following conclusions: A. Although the Contracting Officer's interpretation of the Program 1284-S contract is reasonable, nothing in the provisions at issue support the Respondent's position that the only basis for paying the Appellant for collating fold-ins is the total number of fold-ins, not fold-in units. 1. The essence of this appeal is a conflict between the Appellant's insistence that it is entitled to be paid for collating on the basis each 8 1/2 x 11 inch unit within each fold-in, and the Respondent's view that collating is to be billed on the basis of the total number of fold-ins, and not on the number of page units within the fold-ins being collated (R4 File, Tab E). 21/ Both parties integrate several provisions of the contract in dispute to support different interpretations concerning payment for collating fold-ins. As indicated above, the Appellant looks to Section 4, Parts II and IV, ¶ (d) of the IFB to support its view that it is entitled to payment for collating on the basis of each 8 1/2 x 11 inch unit or leaf within each fold-in. Meanwhile, the Respondent sees the third paragraph of the "Binding" clause of Section 2 (Specifications) of the IFB, which informs potential bidders that collating will be required 25 percent of the time, and the Section 3 (Determination of Award) estimates of work under the contract, as the foundation for its interpretation that collating is to be billed and paid for on the basis of the total number of fold-ins. 2. The first task facing the Board in resolving this controversy is to look at the contract to see if the usual rules of contract construction will fix a single meaning of the disputed terms -"fold-in," "fold-in unit" and "leaf." Cf., R.C. Swanson Printing and Typesetting Company, supra, Sl. op. at 42. In doing so, the Board must look to the contract as a whole, harmonizing and giving meaning to all of its parts, if reasonably possible. Hol-Gar Manufacturing Corporation v. United States, supra, 352 F.2d 972; B. D. Click Company v. United States, supra, 614 F.2d 748; Fortec Constructors v. United States, supra, 760 F.2d at 1292; General Business Forms, Inc., supra, Sl. op. at 16. 3. The contract in dispute covers the production of fold- ins (R4 File, Tab A, p. 1). However, the Board is unable to find a precise or consistent definition or application of the terms "fold-in," "fold-in unit" and "leaf" within the contract itself. With respect to the word "leaf"-the critical term in this dispute-an examination of the contract discloses only two places where it is specifically defined, and in each instance the meaning is different. In that regard, the second paragraph of Section 4, Part II tells us that a page-size leaf is equal to a "fold-in unit" and the number of such units is derived from a calculation based on the trim size of a particular fold-in (R4 File, Tab A, p. 16). In short, as contended by the Appellant, the second paragraph of Section 4, Part II makes the word "leaf" synonymous with the term "fold-in unit." On the other hand, Section 4, Part IV, ¶ (c) of the contract, which concerns prices for drilling "per 100 leaves," has an explanatory note which tells a potential bidder that for the purpose of counting the number of leaves ". . . each ply of a fold-in will be counted as a single leaf" (R4 File, Tab A, p. 17). 22/ [Emphasis added.] 4. The Respondent may reasonably feel that the Appellant's reliance on the Section 4, Part II definition of fold-in units for collating under Part IV, ¶ (d), is misplaced because that definition limits itself to prices for printing operations and paper, whereas collating is a binding operation. 23/ Similarly, the Respondent might also believe that the Part IV, ¶ (c) "leaf/ply" definition of leaves for computing prices for drilling-another binding operation- indicates an intention to treat such work differently for pricing purposes from printing operations and paper. However, the Board is constrained to note that another provision of the IFB relating to binding operations, namely the "Binding" clause in Section 2, employs essentially the same "leaf/page" and "fold-in unit" terminology used in the second paragraph of Section 4, Part II, when it tells potential bidders that banding will be required for ". . . each fold-in leaf/page in suitable units . . ." (R4 File, Tab A, p. 11). [Emphasis added.] Thus, it is clear to the Board that in the contract under review, the term "leaf" may reasonably be defined to have one meaning in one place, and another meaning in another place, depending on the purpose of the section in which it appears. Cf., Abbot Laboratories v. Young, 920 F.2d 984 (D.C. Cir. 1990). Also cf., Vanscoter v. Sullivan, 920 F.2d 1441 (9th Cir. 1990) (Even identical words appearing more than once in the same section may be construed differently if it appears they were used in different places with a different intent.). 5. It is obvious to the Board that the drafter of the IFB went out of his/her way to give special meanings to the word "leaf" in those places where it was deemed important; i.e., Section 4, Part II, and Part IV, ¶ (c). Hence, it seems to the Board that if the Respondent had wished the word "leaf" to be synonymous with a "fold-in" for the purpose of calculating the charges for collating under Section 4, Part IV, ¶ (d), the drafter could have made that clear by adding a phrase such as "per 100 leaves (or plies) of fold-ins of any size," or something equally appropriate. In a like vein, the drafter could have added an explanatory note defining the term "leaf" for collating under Section 4, Part IV, ¶ (d) similar to the one in Section 4, Part IV, ¶ (c), which defines "leaf" for the purpose of pricing the drilling of fold-ins, since both line items refer to binding operations and ask for price quotations "per 100 leaves." 24/ In either case, if the drafter of the IFB had taken these steps it would have been clear that a "leaf" for the purpose of Section 4, Part IV, ¶ (d) meant something other than a "fold-in unit." That the drafter failed to do so is not without some significance. Consequently, the Board concludes that the use of the word "leaf," as applied to binding operations under the contract, including collating, is not so precise as to support only the meaning ascribed to it by the Respondent. 6. The Respondent's belief that only the total number of fold-ins should be counted when billing and paying for collating is derived from an arithmetic computation applied to the Government's estimate in the IFB of the number of collating operations to be performed over the life of the contract multiplied by 100 and divided by 25 percent. 25/ On review and analysis of the contract,the Board cannot say that the Respondent's interpretation is outside the "zone of reasonableness." Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 506 (citing, WPC Enterprises, Inc. v. United States, supra, 163 Ct.Cl. at 6). In the Board's view, the portions of the contract relied on by the Respondent-the third paragraph of the "Binding" clause of Section 2 (Specifications) of the IFB and the Section 3 (Determination of Award) estimates-permit the inferences it draws, which are rational and consistent with the contract language, id. (citing, Sun Shipbuilding & Drydock Co. v. United States, supra, 183 Ct.Cl. at 372), and do not rest on any obvious errors, gross discrepancies, or glaring gaps. Id. (citing, WPC Enterprises, supra, 163 Ct.Cl. at 6). 7. However, to recognize that the Respondent's interpretation of the contract falls within "zone of reasonableness," is not the same as saying that the Contracting Officer's position is the only basis for paying the Appellant for collating fold-ins. That is, the Board sees nothing in the contract specifications themselves which would lead to a finding, as urged by the Respondent, that the only basis for paying the Appellant for collating fold- ins is the total number of fold-ins themselves. 8. Finally, it seems to the Board that the Respondent's position in this appeal relies, in part, on " . . . the unstated premise that a party bidding on a [G]overnment contract is charged with knowing the principle of contract interpretation; i.e., that an interpretation giving meaning and effect to all portions of an instrument is preferred to an interpretation that leaves any portion meaningless." Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 508. For the reasons expressed by the Court in Fry Communications, this Board rejects that position. While the Board should interpret contracts with that principle in mind, the operative inquiry here, discussed below, is simply whether the interpretation advanced by the Appellant-ostensibly staffed by laymen-is reasonable. Id. B. The Appellant's interpretation of the contract relying on fold-in units as the basis for payment for collating, also falls within the "zone of reasonableness." Thus, the contract language is ambiguous. Furthermore, the ambiguity is latent, so the doctrine of contra proferentem applies. 1. Although the Board recognizes the validity of the Respondent's interpretation, the real issue in this appeal is whether or not the meaning given to the disputed contract provisions by the Appellant also falls within the "zone of reasonableness?" The Respondent cannot prevail simply by showing that its interpretation of the IFB is somehow "better" than the Appellant's, Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 505-06, or that the Appellant's interpretation, even if reasonable, is not the "most" reasonable. General Business Forms, Inc., supra, Sl. op. at 23. Since the Board has already found that the Respondent's interpretation lies within the "zone of reasonableness," a similar finding with respect to the Appellant's interpretation means, ipso facto, that the specifications are ambiguous. R.C. Swanson Printing and Typesetting Company, supra, Sl. op. at 41; Fry Communications, Inc./InfoConversion Joint Venture, supra, Sl. op. at 9 (Decision on Remand). 2. The Appellant interprets the word "leaf" in Section 4, Part IV, ¶ (d) as meaning the same as "fold-in unit," as defined in Section 4, Part II, notwithstanding that the former applies to collating and the latter is related to paper and printing operations. The question for the Board, therefore, is whether it was reasonable under the circumstances for the Appellant to extend the Part II definition of "leaf" to Part IV, ¶ (d), for the purpose of calculating the number of leaves for pricing collating under Part IV? To test the reasonableness of the Appellant's interpretation in this case, the Board must ask whether an ordinary contractor, looking at the contract specifications in question, could have reasonably concluded that the price for collating fold-ins "per 100 leaves" was to be computed on the basis of "fold-in units," as defined in Section 4, Part II, because "leaves" and "fold-in units" meant essentially the same thing. Cf., General Business Forms, Inc., supra, Sl. op. at 18. An ordinary contractor under these circumstances is not expected to be a mind reader in ascertaining the intent of the drafter of the contract. Cf., Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 508; General Business Forms, Inc., supra, Sl. op. at 22 ("A contractor . . . cannot . . . be held to a standard of clairvoyance even where some ambiguity exits . . .".). 3. The Board believes that the Appellant's interpretation, when measured against the above standard, clearly falls within the "zone of reasonableness." The Board has reached this conclusion for two basic reasons. First, as indicated above, the contract itself was imprecise and inconsistent in defining and/or applying the critical terms "fold-in," "fold-in unit" and "leaf." This was particularly true insofar as the IFB's treatment of pricing and billing for binding operations under the contract; e.g., the prices "per 100 leaves" for drilling and collating in Section 4, Part IV, can be computed differently because the special instructions which count each ply of a fold-in as a single leaf for drilling are not repeated for, and do not apply to collating. Hence, the Board has concluded that the term "leaf" in the disputed contract may reasonably be defined to have different meanings depending on the purpose of the section in which it appears. Cf., Abbot Laboratories v. Young, supra, 920 F.2d 984; Vanscoter v. Sullivan, supra, 920 F.2d 1441. Second, it was not unreasonable under the circumstances for the Contractor to take the Respondent's failure to challenge its interpretation of the identical language in its 1988-1989 contract as confirming the correctness of its method for calculating charges for collating under the 1991-1992 contract. 26/ Accordingly, the Board also concludes that the portions of the contract relied on by the Appellant-the second paragraph of Section 4, Part II and Part IV, ¶ (d)-support the inferences it draws, which are rational and consistent with the contract language. Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 506 (citing, Sun Shipbuilding & Drydock Co. v. United States, supra, 183 Ct.Cl. at 372). 4. Since both the Appellant and the Respondent offer interpretations of the contract which fall within the "zone of reasonableness," the Board is constrained to conclude that the contract is ambiguous because it is " . . . susceptible of two different interpretations, each of which is found to be consistent with the contract's language." 27/ Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 506 (citing, Sun Shipbuilding & Drydock Co. v. United States, supra, 183 Ct.Cl. at 372); General Business Forms, Inc., supra, Sl. op. at 16. Therefore, the next step in the Board's analysis is to determine if that ambiguity is latent or patent, and if latent, whether the Contractor relied on its interpretation at the time it prepared its bid. 5. While the Respondent contends that the contract in dispute is unambiguous, it argues in any case that if an ambiguity exists, it would be patent. R.Brf., p. 7, n. 2. Since the Respondent is attempting to pass the responsibility for its own failings-its failure to produce an accurate, unambiguous contract-onto the shoulders of the Appellant, it has the burden to show the existence of special circumstances before the financial burden flowing from the Government's fault will be shifted. 28/ B.L.I. Construction, Inc., supra, 91-1 BCA ¶ 23,316, at 116,923. 6. The IFB was patently ambiguous if it contained a gross discrepancy, an obvious error in drafting, or a glaring gap. 29/ See, e.g., Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 509 (citing, WPC Enterprises, Inc. v. United States, supra, 163 Ct.Cl. at 6). Whether an ambiguity is patent or not is determined by an objective test; i.e., what would a reasonable man find to be patent and glaring? Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 509 (citing, Max Drill, Inc. v. United States, supra, 192 Ct.Cl. at 626). This is so, because a potential contractor ". . . is not normally required (absent a clear warning in the contract) to seek clarification of any and all ambiguities, doubts, or possible differences of interpretation." WPC Enterprises, Inc. v. United States, supra, 163 Ct.Cl. at 6. For the Board to find a patent ambiguity here, its examination of the contract, through the eyes of a reasonable man, must disclose such gross discrepancies, obvious errors, or glaring gaps; otherwise, it can only conclude that the ambiguity is not patent. Id. On the other hand, if the Board finds that the ambiguity is patent, then its inquiry is at an end, since it is clear that the Appellant failed to seek clarification of the IFB prior to bidding. Id. (citing, Newsom v. United States, supra, 230 Ct.Cl. at 303). 7. In the Board's view, nothing on the face of the contract amounts to the sort of gross discrepancy, obvious error in drafting, or a glaring gap, which would trigger the Appellant's legal duty to seek an interpretation from the Contracting Officer concerning the meaning of the term "leaf" in Section 4, Part IV, ¶(d) before establishing its bid price for collating "per 100 leaves." Cf., Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 506 (citing, WPC Enterprises, supra, 163 Ct.Cl. at 6); General Business Forms, Inc., supra, Sl. op. at 21. The facts in this case support the conclusion that the Appellant did not become aware of the Respondent's contrary view of the contract language until its bills for collating were disputed and rejected by GPO. Furthermore, there is no evidence that any other bidder responding to the IFB questioned the meaning of the term "per 100 leaves" in Section 4, Part IV, ¶ (d) or that the Respondent thought the pricing provision for collating to be anything but clear on its face. Moreover, even if the Board agreed with the Respondent that the Appellant should have seen that its interpretation of the term "per 100 leaves" for the purpose of collating conflicted with the Government's contractual estimates for that particular binding operation, it cannot say that the Contractor also would have recognized that the ambiguity which existed was so "gross," "glaring" or "obvious" that it had a duty to ask the Contracting Officer to resolve it. 30/ Accordingly, the Board concludes that the ambiguity in this case is latent, not patent. Consequently, the Appellant's failure to contact the Contracting Officer about the "anomaly" between its interpretation and the Government's estimates for collating is not fatal under these circumstances, because the law does not require a potential contractor to seek a clarification of any and all ambiguities, doubts, or possible differences in interpretation. WPC Enterprises, Inc. v. United States, supra, 163 Ct.Cl. at 6. 8. The Board has found that the ambiguity here is latent. Thus, under accepted principles it must apply the doctrine of contra proferentem if the Appellant relied on its interpretation when it prepared its bid. 31/ Fry Communications, Inc./ InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 510. The Appellant has the burden of proof on the "reliance" issue. Id. 9. The record in this case does not contain any worksheets, notes or other materials which might shed some light on how the Appellant arrived at its low bid. Id. See also, Fry Communications, Inc./InfoConversion Joint Venture, supra, GPO BCA 9-85, Sl. op. at 35-36 (Decision on Remand). However, the Appellant clearly raises the "reliance" issue in its Complaint, and the relevant facts are essentially admitted by the Respondent. 32/ Complaint, ¶¶ 9, 10; Answer, ¶¶ 9, 10. Thus, it is basically undisputed that: (a) the Appellant's 1988-1989 contract contained a pricing provision which allowed a contractor to charge for collating fold-ins on the basis of "per 100 leaves;" (b) in preparing its bid for the 1988-1989 agreement, the Appellant interpreted the word "leaves" in that pricing provision to mean "fold-in units," and calculated its bid price for collating accordingly; (c) the Contractor's charges for collating under the 1988-1989 contract were based on its interpretation of that pricing provision, and the bills it submitted to the Respondent for that task were paid in full; (d) at no time during the Appellant's performance of the 1988-1989 contract did the Respondent challenge the Contractor's method of computing its charges for collating; (e) the IFB for the 1991-1992 contract-the contract at issue here -contained a pricing provision for collating fold-ins which was identical to the one in the 1988-1989 agreement; (f) in responding to the IFB the Appellant gave the phrase "per 100 leaves" the same meaning it had in 1988-1989, and submitted a bid for the 1991-1992 agreement based on its understanding that a "leaf" for collating purposes was synonymous with a "fold-in unit;" and (g) the charges submitted by the Appellant for collating fold-ins under the 1991-1992 contract were calculated by the same method which the Contractor had used in 1988-1989. On balance, the Board believes that these undisputed facts support a resolution of the "reliance" issue in favor of the Appellant. In the Board's opinion, when the Appellant saw that the pricing provision for collating in the 1991-1992 IFB was identical to the one in its previous 1988-1989 contract, it simply applied the same interpretation to the key words that it had used two years earlier. Since its interpretation under the 1988-1989 contract had not been challenged by the Respondent, and its bills for collating based on that interpretation had been paid in full, it would have been strange indeed if the Appellant had looked at those words afresh and given them a new meaning. Instead, the Appellant merely assumed that its earlier interpretation was correct and prepared its bid for collating under the 1991-1992 contract with that understanding in mind. Certainly, under these circumstances it was not unreasonable for the Appellant to rely its unchallenged interpretation of an identical pricing provision for collating in its earlier contract at the time it prepared its bid in response to the 1991-1992 IFB. 33/ 10. In summary, the Board finds that the pricing provision for collating fold-ins in the 1991-1992 contract is latently ambiguous, and that the Appellant relied on its interpretation of the disputed language when it prepared its bid. Accordingly, under well-accepted principles the Board will apply the doctrine of contra proferentem to the facts before it, and shift the risk of the ambiguity in this case to the Respondent, who drafted the contract language in dispute. To rule otherwise would be for this Board to sanction the sort of "hidden trap" for contractors doing business with the Government which the courts have long sought to protect them against. Cf., Fry Communications, Inc./ InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 503 (citing, Sturm v. United States, supra, 190 Ct.Cl. at 697). 34/ DECISION In light of the foregoing analysis, the Board finds and concludes that: (a) both the Appellant and the Respondent have advanced interpretations of the pricing provision for collating fold-ins in the 1991-1992 contract which fall within the "zone of reasonableness," thus the contract language is ambiguous; (b) the ambiguity is latent; and (c) when the Appellant prepared its bid in response to the IFB, it relied on its interpretation of the disputed terms. THEREFORE, the decision of the Contracting Officer rejecting the Appellant's interpretation of the contract and denying its claim to be compensated for collating fold-ins on the basis of "fold-in units" is REVERSED, and the appeal is allowed. FURTHERMORE, the matter is REMANDED to the Contracting Officer with instructions to compute the amount due the Appellant under this Decision, and to make the appropriate arrangements for payment accordingly. General Business Forms, Inc., supra, Sl. op. at 23. It is so Ordered. _______________ 1. The Contracting Officer's appeal file, assembled pursuant to Rule 4 of the Board's Rules of Practice and Procedure, was delivered to the Board on March 13, 1992. GPO Instruction 110.12, Subject: Board of Contract Appeals Rules of Practice and Procedure, dated September 17, 1984 (Board Rules), Rule 4(a). It will be referred to hereafter as the R4 File, with an appropriate Tab letter (and a page number for Tab A) also indicated. The R4 File consists of five documents identified as Tab A through Tab E. 2. In this case, the Appellant elected to have its appeal processed under the Board's optional Accelerated Procedure. Board Rules, Rules 12.1(b) and 12.3. See, Appellant's Complaint, dated March 12, 1992. Furthermore, by letter dated April 20, 1992, the Appellant advised the Board that it desired to have its appeal decided on the record without a hearing. Board Rules, Rule 8. 3. Accelerated Procedure decisions are normally brief and contain only summary findings of fact and conclusions. Board Rules, Rule 12.3(b). In this case, however, the Board believes that the nature of the controversy entitles the parties to a fuller explanation of the facts, issues, and reasons for the Board's decision than would be found in a typical Accelerated Procedure case. The Board also notes that this decision, unlike its opinions under the Small Claims (Expedited) Procedure, may be cited as precedent in future appeals. Cf., Graphics Image, Inc., GPO BCA 13-92 (August 31, 1992), Sl. op. at 2, fn. 3; Board Rules, Rule 12.2(d). 4. According to the record, Program 1284-S has been issued by the NYRPPO since December 1988, for four separate annual terms. Respondent's Brief, dated August 10, 1992, Declaration of Contracting Officer Francis Dillon, ¶ 3 (R. Brf.). The Appellant was the successful contractor on the first contract, which ran from December 1988 through December 1989. From January 1990 to January 1991, Program 1284-S was awarded to Braceland Brothers of Stubenville, Ohio. Id. For the contract at issue here-covering the period February 1991 to January 31, 1992-the Appellant was again the successful bidder. Id. For the period beginning February 1992, Program 1284-S was awarded to Technical Publications. Id. 5. Program 1284-S was also governed by the applicable articles of GPO Contract Terms, GPO Publication 310.2, effective December 1, 1987 (Rev. 9-88) (GPO Contract Terms), and GPO's Quality Assurance Through Attributes Program, GPO Publication 310.1 (Revised November 1989) (R4 File, Tab A, p. 2). 6. The contract in question was a "direct-deal term contract." As explained in the GPO Agency Procedural Handbook, GPO Publication 305.1, dated March 1987 (GPO Handbook): "[d]irect- deal term contracts allow the customer agency to place print orders (GPO Form 2511) directly with contractors rather than routing them through the GPO for placement." GPO Handbook, Section IV, ¶ 1, at 8. The purpose of this method of contract administration is " . . . to ensure that agency printing needs are met in the most effective and efficient manner possible." Id. It should be noted, however, that agency direct-deal authority ". . . extends only to the placement of print orders and to the transmission of copy and proofs. . . . All other authority rests with GPO's Contracting Officers." GPO Handbook, Section IV, ¶ 2, at 9. See, R.C. Swanson Printing and Typesetting Company, GPO BCA 31-90 (February 6, 1992), Sl. op. at 6, fn. 4. 7. The Appellant's interpretation was consistent with its understanding of an identical pricing provision in its 1988-89 Program 1284-S contract. Appellant's Complaint, dated March 12, 1992, ¶ 9; Exhibit A (Complaint). See, note 4 supra. According to the Appellant, its successful bid on the earlier contract was based on the same interpretation of that identical language, and its invoices were paid in full by the Respondent without challenge. Complaint, ¶¶9, 10. 8. Contracting officers do not normally receive and review vouchers submitted for payment by contractors. However, if there is a dispute, or if there is a question regarding the contract specifications, the contracting officer is contacted to resolve any questions concerning the interpretation of the contract. R.Brf., Declaration of Contracting Officer Francis Dillon, ¶ 4 (Dillon Declaration). 9. The Appellant also relied on specifications concerning payment for fold-ins in other contracts awarded by the Respondent, including Programs 1268-S and 1262-M issued by the NYRPPO (R4 File, Tab C). However, the Board has indicated on several occasions in the past that it has no jurisdiction over matters pertaining to other contracts unrelated to the one under review in the case before it, and will not consider them. See, e.g., B. P. Printing and Office Supplies, GPO BCA 14-91 (August 10, 1992), Sl. op. at 15. 10. Hence, the Appellant contends that as expressed in Section 4, Part II, the terms "leaf" and "fold-in unit" are synonymous, with the latter being a derivative of a fold-in's trim size. Appellant's Reply Brief, dated August 21, 1992, p. 2. Consequently, it believes that it correctly interpreted the terms of the contract and properly submitted a bid for collating based on 100 leaves within the fold-ins, i.e., fold-in units. 11. Blanks confirmed his opinion in a memorandum to the Appellant, dated March 5, 1991, which is attached as Exhibit B to the Complaint. Since the memorandum refers to the Appellant's letter of February 27, 1992, it is clear that the date of 1991 is a typographical error. However, while the Appellant may find comfort in the fact that the customer-agency supports its position, Blanks' opinion carries little weight in this proceeding. By GPO regulation, the Navy's "direct deal" authority was expressly limited to the placement of print orders; all other responsibility for the contract, including the authority to interpret it, was retained by the Contracting Officer. See, GPO Handbook, note 6 supra, Section IV, ¶ 2, at p. 9; R.Brf., Dillon Declaration, ¶ 8. 12. In short, the Respondent believes that the Section 4, Part II, definition for fold-in units applies solely to the Appellant's prices for both makeready and running rates for printing, and the amount the Contractor will charge for the paper it supplies. R.Brf., p. 7. In that regard, the Government estimates in the IFB advised the Appellant that it was expected to do 4,022 makereadys, and to print 594,200 units or pages (5,942 times 100) (R4 File, Tab A, p. 13, ¶I.a.(2)). Hence, the Contractor would need paper to print that many page size units. R.Brf., p. 7. 13. Relying on the "Determination of Award" provisions of the IFB, the Respondent contends that the Contractor would have to collate 62,900 "leaves" (R4 File, Tab A, p. 17). R.Brf., p. 7. This figure is arrived at by multiplying 629 separate collating operations by 100 leaves (R4 File, Tab A, p. 13, ¶ IV.d). The IFB told potential bidders that "[c]ollating into sets will be required 25% of the time . . ." (R4 File, Tab A, p. 11). Therefore, the Respondent rejected the Appellant's interpretation as unreasonable because it allows the Contractor to be paid for collating on the basis of 25% of the estimated number of page size leaves ("fold-in units"), which would be 148,550 (594,200 x .25 = 148,440), or more than double the Government's estimate. R.Brf., p. 7. In the Respondent's opinion, the Appellant's position with respect to collating can only be sustained if the IFB estimates of the number of collating operations to be performed over the life of the contract are completely ignored (R4 File, Tab A, p. 13, ¶ IV.d). R.Brf., p. 7. 14. The Appellant's notice of appeal was mistakenly addressed and mailed to Mr. Paul Barlowe, an employee in the Regional Operations Office of GPO's Printing Procurement Department, who delivered it to the Board. Board Rules, Rule 1(a), 2. Even though both the "Disputes" clause and the Board's rules require a notice of appeal to be sent directly to the Board, GPO Contract Terms, Contract Clauses, ¶ 5(b), Board Rules, Rule 1(a), under the liberal interpretation followed by most contract appeals boards, including this one, a timely appeal may be served on any other appropriate officer of the agency; e.g., a contracting officer, Government counsel, etc. See, e.g., Marcy Printing Inc., GPO BCA 20-91, Order Dismissing Appeal, dated September 23, 1992, p. 1, fn. 1. See also, e.g., Birken Manufacturing Company, ASBCA No. 37064, 89-1 BCA ¶ 21,248; Brunner Bau GmbH, ASBCA No. 35678, 89-1 BCA ¶ 21,315. But see, Doris Bookout, AGBCA No. 89-147-1, 89-1 BCA ¶ 21,570 (for Department of Agriculture appeals, only notices sent directly to that agency's board of contract appeals are deemed properly filed). 15. The record on which the Board's decision is based consists of: (1) the Notice of Appeal, dated January 10, 1992; (2) the R4 File (Tabs A-E); (3) the Complaint, dated March 12, 1992; (4) the Answer, dated April 13, 1992; (5) the Report of Presubmission Telephone Conference, dated July 14, 1992 (RPTC); (6) the Respondent's Brief, dated August 10, 1992; (7) the Appellant's Reply Brief, dated August 21, 1992. As previously indicated, attached to the Complaint, and incorporated by reference therein, were three Exhibits-the pricing provision for collating fold-ins from the Appellant's 1988-89 Program 1284-S contract (Exhibit A), see note 7 supra; a memorandum from Navy employee Blanks confirming his agreement with the Appellant's method of pricing collating fold-ins (Exhibit B), see note 11 supra; and the revised specification for pricing collating fold-ins from the Program 1284-S contract for 1993 (Exhibit C). Exhibit C is clearly intended to imply that the changed specification amounts to an admission by the Respondent that the language in the Appellant's contract is ambiguous, and that the Government is uncertain of its interpretation. Complaint, ¶ 12. However, it is a well-settled principle of Government contract law that language revisions in a subsequent contract will not justify a finding that the prior contract was ambiguous, or that the Government's interpretation of the former agreement was erroneous. See, e.g., Icono v. United States, 6 Cl.Ct. 149, 156, n. 8 (1983); Martin Lane Co. v. United States, 432 F.2d 1013, 1021, 193 Ct.Cl. 203, 218 (1970). See also, Bay Decking Company, ASBCA No. 33868, 89-2 BCA ¶ 21,834; T.L. James & Company, ENGBCA No. 5328, 89-2 BCA ¶ 21,643; Emerald Maintenance, Inc., ASBCA No. 29540, 86-3 BCA ¶ 19,044; Coastal Dry Dock & Repair Corp., ASBCA No. 31894, 87-1 BCA ¶ 19,618. Therefore, Exhibit C of the Complaint has not been considered by the Board in the context of this decision. 16. The United States Claims Court has observed that: "[a] mere dispute over the terms does not constitute an ambiguity, and an interpretation which is merely possible is not necessarily reasonable." Ceccanti, Inc. v. United States, 6 Cl.Ct. 526, 528 (1984). An ambiguity must have two or more reasonable interpretations and the intent of the parties must not be determinable by the normal rules of interpretation. R.C. Swanson Printing and Typesetting Company, supra, Sl. op. at 42. 17. The importance of the doctrine of contra proferentem, according to the Court in Fry Communications, is that it properly ". . . puts the risk of [latent] ambiguity, lack of clarity, and absence of proper warning on the drafting party which could have forestalled the controversy; it pushes the drafters toward improving contractual forms[,] and it saves contractors from hidden traps not of their own making." Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 503 (citing, Sturm v. United States, 421 F.2d 723, 190 Ct.Cl. 691, 697 (1970)). 18. The purpose of any rule of contract interpretation is to carry out the intent of the parties. Hegeman-Harris and Company, 440 F.2d 1009 (Ct.Cl. 1979). The test for ascertaining intent is an objective one; i.e., the question is what would a reasonable contractor have understood, not what did the drafter subjectively intend. Corbetta Construction Company v. United States, 461 F.2d 1330, 198 Ct.Cl. 712 (1972). See also, Salem Engineering and Construction Corporation v. United States, supra, 2 Cl.Ct. at 806. The provisions of the contract itself should provide the evidence of the objective intent of the parties. 19. For example, within the contract itself, ordinary terms are given their plain and ordinary meaning in defining the rights and obligations of the parties. Elden v. United States, 617 F.2d 254, 223 Ct.Cl. 239 (1980). Similarly, technical terms are given their technical meaning. Industrial Finishers, Inc., ASBCA No. 6537, 61-1 BCA ¶ 3,091; Coastal Drydock and Repair Corporation, supra, 87-1 BCA ¶ 19,618. Likewise, terms special to Government contracts will be given their technical meanings. General Builders Supply Company v. United States, 409 F.2d 246, 187 Ct. Cl. 477 (1969) (meaning of "equitable adjustment"). As for extrinsic evidence of the intent of the parties, the rules of construction allow, among other things, custom and trade usage to explain or define terms. W. G. Cornell Company v. United States, 376 F.2d 199, 179 Ct. Cl. 651 (1967); Harold Bailey Painting Company, ASBCA No. 27064, 87-1 BCA ¶ 19,601 (used to define "spot painting"). However, custom and trade usage may not contradict clear or unambiguous terms. WRB Corporation v. United States, 183 Ct.Cl. 409, 436 (1968). 20. However, a party must be aware of the prior course of dealings. Snowbird Industries, ASBCA No. 33027, 89-3 BCA ¶ 22,065; Wheatley Associates, ASBCA No. 24760, 83-2 BCA ¶ 16,760. 21. In reaching his conclusion that a "leaf" was synonymous with a "fold-in" for the purpose of pricing collating under the contract, the Contracting Officer relied on a comparison of the Appellant's invoices with random billings from Braceland Brothers, the Program 1284-S contractor for the previous year (R4 File, Tab D). From that examination, the Contracting Officer concluded that his interpretation was consistent with "all of the GPO contracts" and must be used in the billing procedure (R4 File, Tab E). However, as previously noted, the Board is limited to considering matters pertaining to the contract under review in the case before it. See, note 9 supra. Similarly, the Board cannot use specifications in a subsequent contract to support a finding that the prior contract was ambiguous, or that the Government's interpretation of the former agreement was erroneous. See, note 15 supra. Therefore, for essentially the same reason that it has disregarded Exhibit C of the Complaint, note 15 supra, the Board believes that the Program 1284-S contract performed by Braceland Brothers is irrelevant to this dispute, and the Contracting Officer's reliance on it is misplaced. 22. In the Board's view, the Respondent's position that the total number of fold-ins forms the basis for billing and paying for collating seems analogous to the drilling definition of fold- in leaves. Indeed, the Board sees no appreciable difference between the explanatory note for drilling which says that in counting the number of leaves ". . . each ply of a fold-in will be counted as a single leaf" (R4 File, Tab A, p. 17, ¶ (c)), and the Contracting Officer's statement to the Appellant the in final decision letter that: "[a] reasonable interpretation of [fold- ins] per 100 leaves would be the actual [fold-in], regardless of size, being one leave [sic] for the purpose of collation. . . ." (R4 File, Tab E). [Emphasis added.] 23. Among other things, binding operations include scoring, folding, gathering or collating, stitching, trimming and drilling. POCKET PAL, 146, 152-53 (International Paper Company, 14th ed., 1989). 24. The question may arise whether the special definition of the word "leaf" in Section 4, Part IV, ¶ (c), or something like it, can be implied in Section 4, Part IV, ¶ (d), merely because both drilling and collating are "binding" operations. However, since it is presumed that the drafter of a document acts intentionally, the rule is clear that where a term is carefully employed in one place and excluded in another, it should not be implied where excluded. Cf., Rusello v. United States, 464 U.S. 16 (1983); United States v. Espinoza-Leon, 873 F.2d 743 (4th Cir. 1989), cert. denied 109 S.Ct. 3257 (1989); Marshall v. Western Union Telegraph Company, 621 F.2d 1246 (3rd Cir. 1980). This maxim of construction, called "inclusio unius est exclusio alterius," simply means that the inclusion of one thing is the exclusion of another. BLACK'S LAW DICTIONARY 906 (4th ed. 1968). Therefore, without some other indication in the contract that potential bidders were expected to quote prices for collating by the same or similar method that they were to use to calculate prices for drilling, there is no basis for the Board to assume that the drafter of the IFB intended such a result. Instead, taking the contract as it finds it, the Board sees that the method of counting each ply of a fold-in as a single leaf is limited to the drilling operation only. 25. On the other hand, as previously indicated, the Respondent seeks to dismiss the Appellant's position concerning counting "leaves" for collating by arguing that the Contractor's interpretation would allow payments for collating at more than double the rate estimated by the Government, and can only be sustained if those estimates are completely ignored. See, note 13 supra. R.Brf., p. 7. However, as the "Determination of Award" provisions of the contract relied on by the Respondent state, in pertinent part: ". . . the following units of production . . . are the estimated requirements to produce 12 months of orders under this contract. These units do not constitute, nor are they to be construed as, a guarantee of the volume of work which may be ordered for a like period of time." (R4 File, Tab A, p. 13). [Emphasis added.] Furthermore, the "Requirements" clause tells a contractor that: "[t]he Government shall not be required to purchase from the contractor, requirements in excess of the limit on total orders under this contract, if any" (R4 File, Tab A, p. 6). [Emphasis added.] Consequently, even though the estimates in the contract are based on a good faith review of the previous year's activity, the clear import of this language is to tell potential bidders that the actual volume of work, including collating, is not fixed but may be more or less than the Government's "best guess." Hence, there is nothing in the Government's estimates themselves which would have put the Appellant on notice that its larger figures for collating based on computing "fold-in units" instead of "fold-ins," were not in harmony with the forecast of work under the contract. 26. The Board wishes to emphasize that it is not saying that the earlier acquiescence of the Government amounts to a waiver or that the Respondent is estopped from asserting a contrary viewpoint now. See notes 33 and 34 infra. Rather, the Board is merely stating that for the limited purpose of testing the reasonableness of the Appellant's interpretation, the Contractor was entitled to place some reliance on the fact that its present interpretation was consistent with the meaning it placed on the identical language in its earlier contract, which the Respondent had not disputed at the time. 27. Because the Board has concluded that both parties have advanced reasonable interpretations of the contract, it applies the rulings of the Court in Fry Communications to this case and rejects the Appellant's primary position, namely that the specifications in question are clear and unambiguous. Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 509, fn. 10. 28. As stated by the Department of Transportation Board of Contract Appeals (DOTBCA): "The situation is somewhat analogous to the last clear chance doctrine in tort law, where one will be absolved of the consequences of his/her negligence if the person injured should have observed the results of that negligence and in the exercise of reasonable care avoided the injury." B.L.I. Construction, Inc., DOTBCA No. 2147, 91-1 BCA ¶ 23,316, at 116,923, fn. 9. 29. The DOTBCA has defined a "glaring gap" for the purpose of revealing a patent ambiguity as one which ". . . leap[s] from the page at the viewer, assaulting the viewer's senses, vision, and mind to such an extent that a reasonable person cannot avoid observing it." B.L.I. Construction, Inc., supra, 91-1 BCA ¶ 23,316, at 116,924. 30. As the Board has previously observed, those estimates are merely the Government's good faith "best guess" of the volume of such work, and nothing in the estimates themselves would have warned the Appellant that its larger figures for collating based on computing "fold-in units" instead of "fold-ins," were in conflict with the Respondent's forecast of work under the contract. See note 25 supra. 31. As explained by the Court in Fry Communications: "This rule is aimed at preventing contractors from recovering additional compensation under a contract based on a mere afterthought, i.e., based on an interpretation of the contract not contemplated by the contractor at the bidding stage. Put another way, the actual-reliance rule forces the contractor to prove that it has actually been injured as a result of the [G]overnment's inclusion of a latently ambiguous provision in the contract. If the contractor did not actually rely on its interpretation when formulating its bid, it cannot later claim that it will lose money if its post-bid interpretation is not adopted." Fry Communications, Inc. / InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 510. [Original emphasis.] 32. On the other hand, the record on the "reliance" issue before the Court in Fry Communications consisted of allegations and self-serving statements made by the contractor after the dispute arose, which were neither admitted nor denied by the Government. Fry Communications, Inc./InfoConversion Joint Venture v. United States, supra, 22 Cl.Ct. at 510. 33. In so holding, the Board is not saying that there was an established course of dealing between the parties which shows the meaning of the current contract and amounts to a waiver of an express contract requirement. Cf., Gresham & Company, Inc. v. United States, supra, 470 F.2d 542; L.W. Foster Sportswear Company v. United States, supra, 405 F.2d 1285; Coastal States Petroleum Company, supra, 87-1 BCA ¶ 19,618. See also, Laborers' International Union of North America, LBCA No. 83-BCA-11, 84-3 BCA ¶ 17,658. In that regard, the Board is well aware that the doctrine of course of dealing ". . . is not a tool for sanctifying a party's unallowable conduct upon a showing that the party got by with it several times before." Mission Van and Storage Company, Inc., GSBCA No. 7386-R, 85-2 BCA ¶ 18,032, at 90,493. Indeed, a single prior contract is generally insufficient to support a finding that there was an understood course of dealing between the parties. Longmire Coal Corporation, ASBCA No. 31569, 86-3 BCA ¶ 19,110. Compare, Western Avionics, Inc., ASBCA No. 33158, 88-2 BCA ¶ 20,662 (the contractor could reasonably rely on a practice established under 50 prior contracts over a 16-year period which deviated from the precise contract language). Rather, the Board is merely stating here that the 1991-1992 IFB was ambiguous, and there was nothing in the Respondent's administration of the prior 1988-1989 agreement which would have alerted the Appellant, at the time it prepared its bid, to the fact that the Government had a different opinion as to the meaning of the disputed language. 34. In light of the Board's decision on the "ambiguity" issue, it is unnecessary to address the remaining question in this appeal, namely, whether or not the Respondent would be estopped from recovering the overpayments made to the Appellant for collating fold-ins simply because it had paid the Contractor on the basis of "fold-in units" under an identical pricing specification in the 1988-89 contract? However, the Board does note its agreement with the Respondent that, as a general rule, the Government is not estopped from rectifying an earlier error in contract administration and may recover funds erroneously paid. United States v. Ulvedale, 372 F.2d 31, 35 (8th Cir. 1967). See also, Assignees for the Benefit of Creditors of A. Hoen & Co., Inc., GPO CAB Panel 9-82 (October 21, 1983), Sl. op. at 4-5, where the Board's predecessor contract appeals panel stated that: " . . . it has long been recognized that the Government has a right, unlike those of other creditors, to set- off the amounts due it against any funds due the contractor by the Government. [Citations omitted.] This right has been held to be an inherent right in the United States. [Citation omitted.]".
