GIP INDIANAPOLIS, LLC,
Appellant,
v.
GENERAL SERVICES ADMINISTRATION,
Respondent.
Diana Parks and Hadeel N. Masseoud of Curran Legal Services Group, Inc.,
Marietta, GA, counsel for Appellant.
Jennifer S. Scott, Office of General Counsel, General Services Administration,
Washington, DC, counsel for Respondent.
Before Board Judges ZISCHKAU and NEWSOM.
ZISCHKAU, Board Judge.
Appellant, GIP Indianapolis, LLC (GIP), appeals the decision of respondent, General
Services Administration (GSA), denying GIP’s claim for reimbursement of amounts withheld
from rent payments.  GIP elected disposition of this appeal under the accelerated procedure
in Board Rule 53, 48 CFR 6101.53 (2024), and the parties agreed to resolve the appeal on
the written record under Board Rule 19.  GSA argues that it properly recalculated the
monthly rent payments based on an analysis of the annual consumer price index (CPI) and
the timing of the calculations for the base operating rent.  GIP argues that GSA’s
recalculation ignores the plain terms of the bilateral lease amendments which specified the


CBCA 8555 2
actual amount of the base operating rent.  We agree with GIP and conclude that GSA must
reimburse GIP for the amount of the rent it withheld plus applicable interest.
Background
The parties submitted into the record a joint statement of stipulated facts (JSSF),
which forms the basis for our findings in this matter.
GIP and GSA entered into lease number GS 05B-LIN17060/GS-05B17060 (the lease)
concerning the property located on Lakeside Boulevard in Indianapolis, Indiana, on August
1, 2002.  JSSF ¶ 1.  Paragraph 12 of the base lease states that operating cost adjustments
would be computed based on a base rate of $3.10 per rentable square foot (RSF).  Id. ¶ 2. 
Section 3.4 of the Solicitation for Offers (SFO), which was made a part of the lease, governs
the calculation of adjusted rent for changes in operating costs, stating that:
The amount of adjustment will be determined by multiplying the base rate by
the percent of change in the Cost of Living Index.  The percent change will be
computed by comparing the index figure published in the month of the lease
commencement date with the index figure published in the month which
begins each successive 12-month period.
Id. ¶ 3.  Section 3.5 states that “[t]he base for the operating costs adjustment will be
established during negotiations based upon [American National Standards Institute
(ANSI)/Building Owners and Managers Association (BOMA)] Office Area square feet.” 
Id. ¶ 4.  The original ten-year lease was extended through various lease amendments.  Lease
amendment 14 was executed on September 26, 2018, reflecting a reduction in leased space
and amending paragraph 12 of the lease, stating:
Paragraph 12 of the lease is hereby amended by deleting the existing text in its
entirety and replacing it with the following in lieu thereof:
12.  For the purposes of computing future operating cost adjustments in
accordance with the section entitled ‘OPERATING COSTS, (SEP 2000),’ it
is mutually agreed that effective November 1, 2018, the base rent from which
future adjustments shall be made is $5.50 per rentable square foot.  No
operating cost adjustment shall be made on November 1, 2018; the next time
an operating cost adjustment shall be completed is on November 1, 2019.
Id. ¶ 5.

CBCA 8555 3
Lease amendment 17, which was executed on January 23, 2023, slightly reduced the
RSF; specified adjusted operating costs of $366,168.15; specified adjusted annual rent of
$1,104,976.15; and specified an operating cost base of $5.50 per RSF by stating:
OPERATING COST BASE FOR PURPOSES OF ADJUSTMENT
REMAINS $5.50 per RSF.  THE OPERATING COST BASE WILL
CONTINUE TO BE ADJUSTED IN ACCORDANCE WITH SFO
PARAGRAPH 3.4 OPERATING COSTS (SEP 2000) OF THE LEASE.
JSSF ¶ 6.
Lease amendment 18, which was executed on August 31, 2023, specified adjusted
operating costs of $366,168.15, and specified an operating cost base of $5.50 per RSF by
stating:
OPERATING COST BASE FOR PURPOSES OF ADJUSTMENT
REMAINS $5.50 per RSF.  THE OPERATING COST BASE WILL
CONTINUE TO BE ADJUSTED IN ACCORDANCE WITH PARAGRAPH
3.4 OPERATING COSTS (SEP 2000) OF THE LEASE.
OPERATING COSTS CITED IN THE TABLE ABOVE REFLECT
ADJUSTMENT AS OF August 1, 2022.
JSSF ¶ 7.
Lease amendment 19 was executed on July 26, 2024, and specified adjusted operating
costs of $378,826.24, from July 26 to October 31, 2024, and $378,826.24, from November 1,
2024, to October 31, 2029, and further stated that:
OPERATING COST BASE FOR PURPOSES OF ADJUSTMENT
REMAINS $5.50 PER RSF.  THE OPERATING COST BASE WILL
CONTINUE TO BE ADJUSTED IN ACCORDANCE WITH PARAGRAPH
3.4 OPERATING COSTS (SEP 2000) OF THE LEASE.
OPERATING COSTS CITED IN THE TABLE ABOVE REFLECT
ADJUSTMENT AS OF August 1, 2023.
JSSF ¶ 8.  GIP received rent payments from GSA during the time period of lease
amendments 17, 18, and 19, based on the adjusted operating costs specified in those lease
amendments.

CBCA 8555 4
GSA issued a demand letter in October 2024, which notified GIP of an overpayment
and which attempted to collect a debt in the amount of $63,671.57.  JSSF ¶ 9.  The demand
letter states:  “PER [lease amendment] 14 Paragraph B (10) effective 11/1/18 there was to
be a new operating cost and will not be adjusted till 11/1/19.  GSA processed the 2018 CPI
and subsequent CPI adjustments using the wrong index.”  Id.  GSA’s demand letter further
stated that “[t]he payment office may initiate procedures, in accordance with applicable
statutory and regulatory requirements, to offset the debt against any payments otherwise due
to you.”  Id. ¶ 10.  On November 1, 2024, GIP disputed the debt.  Id. ¶ 11.  On November 18,
2024, GSA verified the debt according to its interpretation of the lease.  Id. ¶ 12.  On
December 31, 2024, GSA issued a “Final Notice” attempting to collect the debt.  Id. ¶ 13.
The 2025 annual rent, reflecting adjusted operating costs, under lease amendment 19
is $1,264,417.12, which separates out to $105,372.59 per month.  JSSF ¶ 14.  GIP received
rental payments in the amount of $49,535.69, $81,978.04, and $104,737.16 for March, April,
and May 2025, respectively.  Id. ¶ 15.  On June 3, 2025, GIP submitted a claim to the GSA
contracting officer seeking recovery of GSA’s unilateral withholding from rent in the amount
of $83,397.82, plus legal fees.  Id. ¶ 16.  The contracting officer issued a final decision
denying GIP’s claim on July 28, 2025.  Id. ¶ 17.  In the final decision, the contracting officer
stated as follows:
[B]ased on GSA’s re-review of rent payments from November 1, 2018,
through projected August 1, 2025, rent payment, the total overpayment was
$94,023.43. . . .  Of this amount, partial rent withholds from March and April
2025 rent totaled $76,630.28.  The rent was still being slightly overpaid while
GSA is paused in its recovery efforts and rent May-July 2025 has been
overpaying monthly in the amount of $665.15.  Therefore, a final withhold of
$18,723.46 will be applied to the August 2025 rent.
Id. ¶ 18.  
GIP filed a notice of appeal with the Board on August 15, 2025, and, in its notice,
elected the accelerated procedure.  The parties dispute the basis of GSA’s withholding from
rental payments made to GIP.  JSSF ¶ 19.
Discussion
GSA claims that the adjusted operating costs included in lease amendments 17, 18,
and 19 are incorrect due to two separate computation errors made by the GSA personnel who
prepared those lease amendments.  As a result of those errors, GSA states that it mistakenly
overpaid adjusted operating costs to GIP as part of monthly rent payments starting in August

CBCA 8555 5
2019.  The first error, according to GSA, was that its personnel incorrectly used the 2002 CPI
from the original lease rather than the 2018 CPI called for by lease amendment 14.  The
second error made by GSA was that it used the month of August, rather than November, for
applying operating cost escalations to each subsequent lease option year even though,
according to GSA, lease amendment 14 changed the base month to November.  GSA states
that, as of October 2024, the miscalculations resulted in overpayments of $63,671.57.  GSA
further indicates that, after October 2024, overpayments continued, resulting in additional
overpayments of $30,351.86 through August 2025.  GSA states that the total mistaken
overpayments equal $94,023.43.  GSA does not assert any misconduct on the part of GIP.
Rather, GSA asserts that it made calculation errors on multiple occasions which caused it to
include incorrect adjusted operating cost rent amounts in lease amendments 17, 18, and 19. 
GIP argues that the plain language of the lease agreement and amendments entitle it
to recover the deductions that GSA made to its rent payments because bilateral lease
amendments 17, 18, and 19 establish the precise amount of the operating cost adjustments
and total rent payments agreed to by the parties as calculated by GSA.  GIP states that GSA
may not now challenge the amounts bilaterally and expressly agreed to in the lease
amendments or unilaterally reform those agreements.
Contract interpretation begins with the plain language of the agreement, and where 
the terms are clear and unambiguous, “they must be given their plain and ordinary meaning,
and we may not resort to extrinsic evidence to interpret them.”  Coast Federal Bank, FSB v.
United States, 323 F.3d 1035, 1038 (Fed. Cir. 2003) (en banc) (citing McAbee Construction,
Inc. v. United States, 97 F.3d 1431, 1435 (Fed. Cir. 1996)).  The parties have requested a
decision on the written record under Board Rule 19.  This is especially appropriate because
the material facts have been stipulated and the interpretation of contract modifications,
including lease amendments, is a question of law.  See CESC Mall, LLC v. General Services
Administration, CBCA 7359, et al., 22-1 BCA ¶ 38,226, at 185,651 (citing Varilease
Technology Group, Inc. v. United States, 289 F.3d 795, 798 (Fed. Cir. 2002)).
We agree with GIP that lease amendments 17, 18, and 19 unambiguously establish
both the operating cost rent and the operating cost base and therefore control the parties’ rent
obligations for the relevant lease periods.  Each amendment restates the $5.50 per RSF
operating cost base established in lease amendment 14 and sets a specific, fixed operating
cost base for the applicable lease period.  For example, lease amendment 17 specified
adjusted operating costs of $366,168.15; specified adjusted annual rent of $1,104,976.15; and
specified an operating cost base of $5.50 per RSF.  We have carefully considered GSA’s
argument that it incorrectly calculated these operating rent components which were
incorporated into the lease amendments it prepared.  However, given that both parties signed
these lease amendments, GSA cannot unilaterally undo the agreements into which it and GIP

CBCA 8555 6
entered.  Because GSA and GIP executed bilateral modifications fixing future rent in definite
dollar amounts, those agreements supersede any prior methodology or assumptions used to
derive those figures.  See Amertex Enterprises, Ltd. v. United States, No. 90-684C, et al.,
1995 WL 925961 (Fed. Cl. Dec. 15, 1995), aff’d, 108 F.3d 1392 (Fed. Cir. 1997) (table);
Williams Building Co. v. Department of State, CBCA 6650, et al., 23-1 BCA ¶ 38,328, at
186,124-25, aff’d, No. 2023-2337, 2025 WL 2057994 (Fed. Cir. July 23, 2025).  Even if
lease amendment 14 originally modified the base lease escalation methodology, its terms
cannot override the later, more specific bilateral lease amendments 17, 18, and 19 that
expressly established operating cost rent.  Because the plain and unambiguous terms of lease
amendments 17, 18, and 19 control, we enforce those amendments as written.
Decision
We GRANT the appeal.  GIP is entitled to recover the amounts that GSA wrongly
withheld, plus applicable interest under the Contract Disputes Act (CDA), 41 U.S.C. § 7109
(2018), running from June 3, 2025.
