OPINION BY ADMINISTRATIVE JUDGE THRASHER 
 
Vigor Works, LLC (Vigor or appellant) appealed under the Contract Disputes 
Act (CDA), 41 U.S.C. §§ 7101-7109, from a contracting officer’s final decision 
(COFD) denying appellant’s certified claim in the amount of $5,213,618.  Vigor seeks 
excess costs incurred from what it describes as the government constructively changing 
the contract by accelerating the production pace and sequence through the issuance of 
delivery orders.  The parties have elected a written disposition under Board Rule 11.  
We deny the appeal. 
 
FINDINGS OF FACT 
 
1.  On September 28, 2011, the United States Special Operations Command 
(SOCOM or government) awarded Contract No. H92222-11-D-0080 (the contract) to 
Vigor Works, LLC
1 (R4, tab 9).  The contract was for the design, development, and 
fabrication of Combatant Craft, Medium Mark 1 (CCM Mk 1) systems (compl. ¶ 7; 
R4, tab 9a at 4). 
 
2.  The contract was an indefinite-delivery, indefinite-quantity (IDIQ) contract 
with firm-fixed-price and cost reimbursable contract line items (CLINs) for a total 
period of performance of ten years, including option periods (R4, tab 9 at 3).  Part I of 
the contract contained “THE SCHEDULE” (R4, tab 9 at 2). 
 
1 SOCOM awarded the contract to Oregon Iron Works, Inc. (OIW), but OIW later 
became Vigor Works, LLC (R4, tab 36 at 3; app. supp. R4, tab 25 at 3). 

2 
 
3.  The Schedule, Section B, Supplies or Services and Prices, divided the 
CLINs into four successive periods:   
 
• Base Period (CLINs 0001-0008) 
 
• If applicable, Test Article Refurbishment (CLINs 0009-0018) 
 
• If applicable, Low Rate Initial Production (CLINs 0019-0044) 
 
• If applicable, seven Production/Sustainment Ordering Periods (CLINs 1001-
7027) 
 
(R4, tab 9 at 3)  Each CLIN was to be “set forth under individual delivery order” and 
performed “in accordance with Sections C2 and J” of the contract (see R4, tab 9 at 4-
126). 
 
4.  The Schedule, Section F, Deliveries or Performance, established delivery 
information for each CLIN, including delivery dates for CLINs 0001 to 7027 (R4, 
tab 9 at 1, 133-46). 
 
5.  Part III of the contract contained “LIST OF DOCUMENTS, EXHIBITS 
AND OTHER ATTACHMENTS” (R4, tab 9 at 1).  Section J listed the documents, 
exhibits, and other attachments.  The first item listed is Exhibit A, Contract Data 
Requirements Listings A, E, L, dated August 11, 2011.  (R4, tab 9 at 182; see also R4, 
tab 9k)  The contract required the contractor to provide several Contract Data 
Requirement Lists (CDRLs), including A006 Integrated Program Master Schedule 
(IPMS) (R4, tab 9 at 6). 
 
6.  The Data Description for A006 IPMS provides:   
 
1) The Contractor shall prepare, maintain, and update a 
CCM Mk 1 Integrated Program Master Schedule 
(IPMS) that reflects the Contractor’s program and 
schedule planning.  The Contractor shall ensure the 
IPMS reflects the baseline schedule and all changes 
thereto and maintain the IPMS throughout the life of 
the contract. 
 
 
2 There is no “X” under Part I, Section C, Description/Specs/Work Statement.  The 
contract included the Statement of Work as Attachment 01 under Section J (see 
R4, tab 9 at 1, 182). 

3 
2) The IPMS shall contain the networked, detailed tasks 
necessary to ensure successful program execution.  The 
IPMS is vertically traceable to the Contract Work 
Breakdown Structure (CWBS), and the Statement of 
Work (SOW).  The IPMS shall be used to verify 
attainability of contract objectives, to evaluate progress 
toward meeting program objectives, and to integrate the 
program schedule activities with all related 
components. 
 
3) The IPMS shall also include the accomplishments and 
criteria necessary for the delivery of the CCM Mk 1 TA 
in the first period; deliveries of the LRIP CCM Mk 1 
Systems and FRP CCM Mk 1 Systems in the second 
period; and implementation and execution of the 
performance based logistics process in the second 
period. 
 
(R4, tab 9k at 9) 
 
7.  Section J included the Statement of Work (SOW) as Attachment 01 (R4, 
tab 9 at 182; see also R4, tab 9a).  Section 3.2, Program Schedule, of the SOW stated 
“[Vigor]
3 shall depict and track the CCM Mk1 program schedule in an up-to-date 
Integrated Program Master Schedule (IPMS).  [Vigor] shall maintain the IPMS for the 
duration of the contract.”  (R4, tab 9a at 5)  Additionally, Section 7.3.2 of the SOW 
provided:   
 
[Vigor] shall prepare, maintain, and update a CCM Mk 1 
IPMS that reflects [Vigor’s] program and schedule 
planning.  [Vigor] shall ensure the IPMS reflects the 
baseline schedule and all changes thereto and maintain the 
IPMS throughout the life of the contract.  The IPMS shall 
also include the accomplishments and criteria necessary for 
the delivery of the CCM Mk 1 TA in Period One; 
deliveries of the LRIP CCM Mk 1 Systems and FRP CCM 
Mk 1 Systems in Period Two; and implementation and 
execution of the performance based logistics process in 
Period Two.  [Vigor] shall ensure the IPMS is up to date 
and available at all Government meetings.  [Vigor] shall 
 
3 The SOW refers to OIW, which we previously noted later became Vigor (see n.1). 

4 
submit the CCM Mk 1 IPMS as well as all updates for the 
life of the contract in accordance with CDRL A00[6].4 
 
(R4, tab 9a at 32) 
 
8.  Section J also included a version of Vigor’s IPMS as Attachment 06 (R4, 
tab 9 at 182; see also R4, tab 9f). 
 
9.  Notably, the Solicitation provided that those offerors in the competitive 
range would each be awarded a contract for construction and delivery of a CCM Mk1 
Test Article (TA); support for government testing of the TA; and submission of 
revised proposals, if requested by the government (R4, tab 1 at 183).  After delivery of 
the TA and completion of the government’s testing and assessment, the government 
would downselect to one contractor (R4, tab 1 at 142).  After completing its TA 
evaluation, the government requested a Best and Final Offer (BAFO) from each 
offeror (app. br. at 6; gov’t br. at 24).  Vigor submitted its BAFO in late 2013 (compl. 
¶ 59; R4, tab 179).  Vigor’s BAFO included an updated version of the IPMS (BAFO 
IPMS)
5 (R4, tab 179 at 132-34).  Vigor’s BAFO stated, 
 
[Vigor’s] CCM Mk1 proposed IPMS reflects our program 
and schedule planning and the baseline schedule and all 
changes.  [Vigor] will maintain the IPMS throughout the 
life of the contract. . . . [Vigor] will ensure the IPMS is up 
to date and available at all meetings.  [Vigor] will update 
the IPMS throughout the life of the contract and submit it 
per CDRL A00[6]. 
 
(R4, tab 179 at 30) 
 
10.  In February 2014, the government awarded Vigor the final down select for 
the production contract for CCM Mk1 craft and refurbishment of the TA (R4, tab 21 
at 533).  Effective February 20, 2014, the parties bilaterally executed Modification No. 
P00010 (R4, tab 21).  Modification No. P00010 exercised the options for Test Article 
Refurbishment (TAR), Low Rate Initial Production (LRIP), and the first Full Rate 
 
4 Section 7.3.2 inadvertently refers to CDRL A007.  The government later 
administratively changed this reference from CDRL A007 to CDRL A006 (see 
R4, tab 14 at 83). 
5 Vigor’s Rule 11 brief places significant emphasis on the version of the IPMS that 
was included with its BAFO.  Therefore, for clarity, we refer to this version as 
the “BAFO IPMS.” 

5 
Production (FRP) ordering period.  It also included updated versions of various 
attachments in Section J to include Vigor’s BAFO IPMS.6  (R4, tab 21 at 1, 24) 
 
11.  Vigor subsequently provided several updated versions of the IPMS (see 
generally R4, tabs 121-26, 128-35, 137, 139-57, 159-67, 218-30).7 
 
12.  On March 19, 2014, the parties executed bilateral Modification No. 
P00011, which updated the dates associated with each potential ordering period under 
Section B (R4, tab 23 at 6). 
 
13.  The government issued individual delivery orders consistent with the 
ordering periods in the contract.  The government issued seven delivery orders 
purchasing CCM Mk 1 systems, each of which established delivery dates:   
 
• Delivery Order 0001:  Ordered one TA system and set the period of 
performance as September 27, 2011 to September 26, 2012 (R4, tab 37 at 2, 
6).  Modification No. 08 added TAR, to be delivered August 20, 2014 (R4, 
tab 37i at 7, 9). 
 
• Bilateral Delivery Order 0002:  Ordered two LRIP systems, to be delivered 
March 27, 2015 and June 12, 2015 (R4, tab 38 at 4, 8). 
 
• Delivery Order 0003:  Ordered 2 LRIP systems, to be delivered August 18, 
2015 (R4, tab 39 at 2, 5). 
 
• Delivery Order 0004:  Ordered 1 LRIP system, to be delivered 
November 16, 2015 (R4, tab 40 at 3, 6). 
 
• Bilateral Delivery Order 0005:  Ordered 8 FRP systems, to be delivered 
February 18, 2016, March 31, 2016, May 12, 2016, June 23, 2016, August 
4, 2016, September 15, 2016, October 27, 2016, and December 8, 2016 (R4, 
tab 41 at 3, 6).  Modification No. 01 added a ninth FRP system, to be 
delivered March 17, 2017 (R4, tab 41c at 1, 3). 
 
 
6 The government notes “there is no indication that the parties ever attached this BAFO 
IPMS version to Contract Modification No. P00010.  Instead, as evidenced by the 
Government’s official file copy of that Modification, it appears that a completely 
different schedule from [Vigor’s] BAFO was inadvertently attached as Attachment 
06 to IDIQ Contract Modification No. P00010.”  (Gov’t br. at 88) 
7 The record also includes quite a few versions of the IPMS that predate Modification 
No. P00010 (see R4, tabs 204-17). 

6 
• Bilateral Delivery Order 0018:  Ordered 3 FRP systems, to be delivered 
May 17, 2017, June 21, 2017, and July 26, 2017 (R4, tab 181 at 3, 5). 
 
• Bilateral Delivery Order 0019:  Ordered 1 FRP system, to be delivered 
August 30, 2017 (R4, tab 182 at 3, 5). 
 
14.  The parties subsequently executed several bilateral modifications extending 
the delivery dates on these delivery orders:   
 
• Delivery Order 0001:  Modification No. 12 (R4, tab 180). 
 
• Delivery Order 0002:  Modification Nos. 05, 07, and 08 (R4, tabs 38e, 38g, 
38i). 
 
• Delivery Order 0003:  Modification Nos. 01 and 02 (R4, tabs 39b, 39d). 
 
• Delivery Order 0004:  Modification No. 02 (R4, tab 40f). 
 
• Delivery Order 0005:  Modification Nos. 02, 03, 04, and 05 (R4, tabs 41e, 
41l, 41n, 41t). 
 
• Delivery Order 0018:  Modification Nos. 01, 02, and 03 (R4, tabs 183, 185, 
188). 
 
• Delivery Order 0019:  Modification Nos. 01 and 02 (R4, tabs 184, 186). 
 
15.  On September 1, 2017, Vigor submitted a request for equitable adjustment 
(REA) seeking $4,148,629 for excess costs incurred and a reasonable profit on such 
costs.  The REA alleged that the government made numerous changes in the 
production sequence and pace specified in the contract resulting in Vigor’s excess 
costs.  (R4, tab 168 at 1, 22-23)  Vigor alleges five changes to the contract’s 
production pace and three changes to the contract’s production sequence:   
 
• Production Pace 
 
1. The BAFO IPMS anticipated that TAR would commence in 
January 2014, but the government did not initiate TAR until February 
2014, without adjusting for the 42-day delay. 
 
2. The BAFO IPMS called for just two LRIP systems, but the government 
ordered two additional LRIP systems. 
 

7 
3. The BAFO IPMS provided for delivery of a fifth system in September 
2016, but the government ordered the fifth system to be delivered by 
November 2015. 
 
4. The government ordered the sixth through fourteenth systems to be 
delivered four to nine months earlier than shown in the BAFO IPMS. 
 
5. The government ordered the fifteenth through eighteenth systems to be 
delivered two to three months earlier than shown in the BAFO IPMS. 
 
• Production Sequence 
 
1. The BAFO IPMS provided that LRIP would not begin until TAR was 
finished, but TAR and LRIP were required to run concurrently. 
 
2. The BAFO IPMS had a three-month break between the end of LRIP and 
the start of FRP, but the government placed so many orders that 
appellant was forced to ramp up production and lost this anticipated 
break. 
 
3. The contract required a baseline configuration be finalized by the end of 
TAR, but the government ordered multiple configuration changes after 
TAR. 
 
(Compl. ¶¶ 167-68; see also app. br. at 8-24) 
 
16.  The contracting officer (CO) responded to the REA on April 18, 2018.  The 
CO acknowledged that the contract varied from the original Request for Proposal 
Statement of Work and the ordering periods stated in the contract Schedule, Section B.  
However, the REA response maintained that the changes were implemented via 
formal, bilateral agreements with appellant’s consent.  (R4, tab 169 at 1) 
 
17.  Appellant requested reconsideration of the REA on August 15, 2018 (R4, 
tab 170).  On September 14, 2018, the CO responded to the request for 
reconsideration.  The CO admitted no liability for the allegations made by appellant 
but stated that the CO was willing to settle the REA in a manner equitable to both 
parties.  (R4, tab 171) 
 
18.  The parties continued to exchange correspondence, including an April 24, 
2019, revision to the REA in the amount of $5,903,143.  The CO requested that the 
Defense Contract Audit Agency (DCAA) perform an independent review of the 
amounts proposed by appellant in its revised REA.  (R4, tab 175 at 3)  The DCAA 
audit report, dated January 10, 2020, concluded that appellant’s “proposed amounts do 

8 
not comply with FAR 52.243-1, Changes-Fixed Price and contract terms” (R4, 
tab 175 at 7).  Based on the results of the DCAA audit report, the CO denied the REA 
in full on January 27, 2020.  The CO stated that there was “no financial basis to award 
Vigor any additional consideration beyond numerous, no cost production delivery 
order extensions already granted.”  (R4, tab 173) 
 
19.  On February 10, 2020, appellant resubmitted its REA as a certified claim.  
The claim stated that it was comprised of its REA, request for reconsideration of the 
REA, and a repricing adjustment prepared in response to the DCAA audit report.  (R4, 
tab 176a)  The totaled claimed amount was $5,213,618 (R4, tab 176). 
 
20.  On April 23, 2020, the CO issued a final decision denying appellant’s 
claim (R4, tab 177).  Vigor timely appealed the decision to the Board on July 15, 2020. 
 
DECISION 
 
The Parties’ Contentions 
 
Appellant argues that the government constructively changed the contract by 
accelerating the production pace and sequence through the issuance of delivery orders.  
Appellant maintains that the BAFO IPMS represented the baseline schedule for 
production and that the government’s delivery orders required Vigor “to fabricate 
more systems much earlier than specified in the IPMS, necessitating that Vigor 
perform significant extra work in order to meet the accelerated production schedule.”  
(App. br. at 29-31). 
 
The government maintains that it did not constructively change the contract.  
Rather, the government argues that the contract schedule, as bilaterally modified by 
the parties, represented the parties’ agreement on delivery dates.  (Gov’t br. at 76) 
 
Discussion 
 
For appellant to demonstrate a constructive change, the burden of proof is on 
appellant to show:  (1) that it performed work beyond the contract requirements, and 
(2) that the additional work was ordered, expressly or impliedly, by the government.  
Envtl. Chem. Corp., ASBCA Nos., 59280, 60760, 22-1 BCA ¶ 38,166 at 185,361 
(citing Bell/Heery v. United States, 739 F.3d 1324, 1335 (Fed. Cir. 2014)).  In this 
case, appellant argues that the government altered the contract’s requirements through 
the issuance of delivery orders.  Appellant states that these orders:  (1) required it to 
complete TAR and LRIP concurrently rather than consecutively; (2) increased the 
number of systems it was required to produce during LRIP and eliminated the three-
month break that was supposed to follow LRIP; and (3) accelerated the delivery dates 
of the systems relative to the schedule.  (App. br. at 29-30) 

9 
Appellant maintains that the parties incorporated into the contract the BAFO 
IPMS, which represented the baseline schedule for production.  Appellant notes that 
the SOW refers to the IPMS as the baseline schedule and that each CLIN was to be 
performed in accordance with Sections C and J of the contract.  (App. br. at 31-32)  
Section J of the contract, as modified by Modification No. P00010, included the 
BAFO IPMS (finding 10).  Appellant states, “[w]hile the Contract may have entitled 
the Government to purchase the specified quantities of systems within the enumerated 
ordering periods, the plain language of the Contract also required that all such systems 
were to be produced in accordance with the SOW and IPMS” (app. br. at 32). 
 
Conversely, the government maintains that the IPMS deliverable represented 
appellant’s proposed plan to meet its contractual, agreed-to delivery dates.  The 
government argues that the “CDRL A006 IPMS deliverable was . . . part of a broader 
Government effort to monitor project status and ‘evaluate progress towards meeting 
program objectives’, including the contractor’s ability to satisfy its contractual 
delivery date obligations and ‘ensure successful program execution’” (gov’t br. at 84; 
see also finding 6).  The government argues that appellant understood the IPMS’s role 
by acknowledging the requirement to update it throughout the life of the contract 
(gov’t br. at 82; see also finding 9).  The government notes that appellant in fact 
provided regular updates to the IPMS (gov’t br. at 82; see also finding 11).  The 
government states that “[o]nly when later seeking additional compensation from the 
Government . . . did [appellant] suddenly proclaim that one particular version of its 
IPMS (the “2013 IPMS” from is BAFO) somehow overrode not only all other IPMS 
versions, but even the Contract’s established delivery schedule . . .” (gov’t br. at 86). 
 
This is then a question of contract interpretation, which is a matter of law for 
this Board to decide.  D&J Machinery, Inc., ASBCA No. 62019, 22-1 BCA ¶ 38,118 
at 185,165 (citing Blake Constr. Co. v. United States, 987 F.2d 743, 746 (Fed. Cir. 
1993)).  “In matters of contract interpretation, the preferred approach is to read the 
entire contract as a whole, and to give the language of the contract its plain meaning.  
In doing so, different parts of the contract are to be read in harmony, if possible, and 
preference is given to an interpretation that gives effect to all the terms of the contract 
and does not render one or more of them meaningless.”  ECC Int’l, LLC, ASBCA No. 
58993 et al., 22-1 BCA ¶ 38,073 at 184,887 (citing Jowett, Inc. v. United States, 234 
F.3d 1365, 1368 (Fed. Cir. 2000); Christos v. United States, 300 F.3d 1381, 1384 (Fed. 
Cir. 2002); Air-Sea Forwarders, Inc. v. United States, 166 F.3d 1170, 1172 (Fed. Cir. 
1999); United Pac. Ins. Co. v. United States, 204 Ct. Cl. 686, 693-94 (1974)).  
“Further, a contract will be found to be ambiguous if it is susceptible to more than one 
reasonable interpretation, each of which is consistent with the contract language and 
the other provisions of the contract.”  ECI Constr., Inc., ASBCA No. 54344, 05-1 
BCA ¶ 32,857 at 162,807 (citing Lockheed Martin IR Imaging Systems, Inc. v. West, 
108 F.3d 319, 322 (Fed. Cir. 1997)).  Each interpretation must fall within a “zone of 
reasonableness.”  ECI Constr., 05-1 BCA ¶ 32,857 at 162,807 (citing Metric 

10 
Constructors, Inc. v. NASA, 169 F.3d 747, 751 (Fed. Cir. 1999); Community Heating 
& Plumbing Co. v. Kelso, 987 F.2d 1575, 1578 (Fed. Cir. 1993); WPC Enters., Inc. v. 
United States, 323 F.2d 874, 876 (Ct. Cl. 1963)). 
 
Here, appellant’s interpretation of the contract, specifically the contractual 
significance of the BAFO IPMS, does not fall within the zone of reasonableness.  The 
Data Description for A006 IPMS plainly explains the purpose of the IPMS.  It is a tool 
used to “reflect[] the [c]ontractor’s program and schedule planning.”  It is “used to 
verify attainability of contract objectives, and to integrate the program schedule 
activities with all related components.”  The contractor must “ensure the IPMS reflects 
the baseline schedule and all changes thereto and maintain the IPMS throughout the life 
of the contract.”  (Finding 6)  Section 7.3.2 of the SOW further provides that the 
contractor “shall ensure the IPMS is up to date and available at all Government 
meetings” (finding 7).  Appellant understood its responsibility to update the IPMS.  
Appellant’s BAFO acknowledged that it would “maintain the IPMS throughout the life 
of the contract” and “ensure the IPMS is up to date and available at all meetings” 
(finding 9).  Indeed, appellant updated the IPMS several times.  The record includes 
multiple versions of the IPMS that appellant submitted both before and after the BAFO 
IPMS.  (Finding 11)  We do not believe it is reasonable to maintain that one specific 
version of the IPMS, namely the BAFO IPMS, was intended to be the schedule when 
the contract clearly contemplated that appellant would submit multiple versions of the 
IPMS over time. 
 
The contract included the schedule in Part I (finding 2).  Part I of the contract 
included Sections B and F (findings 2, 4).  Section B established the potential ordering 
periods for each exercised CLIN.  The parties subsequently bilaterally updated the 
dates for the ordering periods.  (Findings 3, 12)  The CLINs were to be “set forth 
under individual delivery order” (finding 3).  Section F established delivery 
information for each CLIN, including delivery dates (finding 4).  Appellant places 
significant emphasis on the fact that Section B incorporates the BAFO IPMS because 
Section B states that each CLIN was to be performed “in accordance with Sections C 
and J of the contract” and Section J contained appellant’s BAFO IPMS as incorporated 
by Modification No. P00010 (findings 3, 10).  Notably, the contract did not contain a 
Section C.  Rather, the contract included the SOW (which would have been Section 
C), as Attachment 01 under Section J (see n. 2).  Reading the contract as a whole in 
harmony with its different parts, it is clear that the CLINs were to be performed in 
accordance with Section J (i.e., the SOW).  The only reasonable interpretation for the 
inclusion of the BAFO IPMS in Section J was that it represented appellant’s “program 
and schedule planning” at that time.  Furthermore, the parties understood that the 
IPMS would change over time. 
 
As noted above, each CLIN was to be “set forth under individual delivery 
order” (finding 3).  After the parties bilaterally exercised the options for TAR, LRIP, 

11 
and the first FRP ordering period, the government issued delivery orders for CCM Mk 
1 systems (findings 10, 13).  Notably, most of the delivery orders were also signed by 
appellant.  The government issued seven delivery orders, which established delivery 
dates for each CCM Mk 1 system.  (Finding 13)  Appellant acknowledged in its brief 
that the CO “had contractual authority to issue each of the delivery orders” and that the 
contract “entitled the Government to purchase the specified quantities of systems 
within the enumerated ordering periods” (app. br. at 30, 32).  Appellant’s contention is 
that the delivery orders differed from what was in the BAFO IPMS.  But, again, 
appellant’s interpretation regarding the contractual significance of the BAFO IPMS 
does not fall within the zone of reasonableness.  Therefore, appellant has failed to meet 
its burden in demonstrating a constructive change to the contract. 
 
Appellant also argues that “[e]ven if the delivery orders were bilateral, they did 
not cover Vigor’s increased costs and would not eliminate Vigor’s right to recover an 
equitable adjustment” (app. br. at 35).  In support, appellant cites Chantilly Constr. 
Corp., ASBCA No. 24138, 81-1 BCA ¶ 14,863.  In Chantilly Constr. Corp., the Board 
allowed the contractor to seek increased costs where “[t]he formal modifications 
which incorporated the site changes compensated appellant solely for the direct costs 
of performing the changed work itself and did not cover appellant's increased costs . . . 
attributable to the delays in the overall project.”  Id.  We do not believe Chantilly 
Constr. Corp. is relevant to our analysis here.  While Chantilly Constr. Corp. involved 
a demonstrated change to the work itself, Vigor has failed to demonstrate that there 
was a constructive change to the contract in this appeal.  Rather, in accordance with 
the contract, the government issued delivery orders for CCM Mk 1 systems and when 
appellant was unable to meet the delivery dates, the parties bilaterally modified the 
delivery orders to extend the delivery dates (findings 13-14). 
 
Finally, appellant argues that any bilateral modifications are invalid for lack of 
consideration because “Vigor received no compensation for accepting an accelerated 
schedule by modification” (app. br. at 37).  But, again, appellant has failed to meet its 
burden in demonstrating that there was an accelerated schedule constituting to a 
constructive change to the contract.  The government did issue delivery orders for 
CCM Mk 1 systems, and the parties did bilaterally modify those delivery orders to 
extend the delivery dates (findings 13-14).  This does not equate to a constructive  
  

12 
change to the contract.  Moreover, appellant received consideration for these bilateral 
modifications to the delivery orders in the form of extended delivery dates.
