Before Board Judges VERGILIO, SULLIVAN, and CHADWICK.
SULLIVAN, Board Judge.
The Miami-Dade Aviation Department (MDAD) twice appealed the denial of its claim
for underpayment of rent for space occupied by federal agency tenants under a lease with the
General Services Administration (GSA).  MDAD alleged that, in 2011, one agency vacated
less space than GSA indicated in its notice of termination and, therefore, MDAD is owed rent
for the space that remained occupied between 2012 and 2017.  The Board dismisses for lack
of jurisdiction MDAD’s first appeal, docketed as CBCA 6689, which was of the contracting
officer’s decision on an uncertified claim.  The Board cannot review the second claim,
docketed as 6784, because MDAD submitted it more than six years after the claim accrued


CBCA 6689, 6784 2
and, thus, the claim is barred by the six-year statute of limitations in the Contract Disputes
Act (CDA).  41 U.S.C. § 7103(a)(4) (2018).  We grant GSA’s motion for summary judgment
and deny MDAD’s second appeal.
Background
I. Relevant Contract Terms
In August 2005, GSA executed a lease for office space to be occupied by three federal
agency tenants, including the Food and Drug Administration (FDA), near the Miami
International Airport.  Exhibit 1 at 1.1  GSA leased from MDAD 56,597 rentable square feet
in exchange for the payment of annual rent of more than $1 million.  Id. (paragraph 3).  The
lease also stated the amount of space that each of the three federal agencies would occupy,
including 14,103 rentable square feet by FDA.  Id.
GSA had the right to measure the square footage to ensure that all of the space offered
was delivered by the lessor:
5.  Rental is subject to the Government’s measurement of plans submitted by
the Lessor or a mutual on-site measurement of the space and will be based on
the rate, per [Building Owners and Managers Association (BOMA)] useable
square foot (PUSF) as noted in paragraph 3 above, in accordance with Clause
26 (PAYMENT), GSA form 3517, General Clauses.  The lease contract and
the amount of rent will be adjusted accordingly, but not to exceed the
maximum BOMA useable square footage requested in Solicitation for Offers
(SFO) [], Paragraph 1.1, (Amount and Type of Space).  Rent for a lesser period
shall be prorated.
Exhibit 1 at 2.  The lease incorporated the terms of the solicitation for offers (SFO), which
contained paragraph 26, clause 552.270-20 PAYMENT (SEP 1999) (VARIATION), which
provided for measurement of the space at the beginning of the lease.  Id. (SFO, General
Clauses).
Paragraph 4 of the lease provided that, “except as provided for in paragraph 17,” GSA
could terminate the lease, in whole or in part, after five years with 120 days notice.  Exhibit 1
at 1.  Paragraph 17 of the lease further provided that GSA could terminate increments of
1 “Exhibit X” refers to the exhibits submitted by the parties in support of their
briefs and joint statement of facts, unless otherwise noted.

CBCA 6689, 6784 3
10,578 rentable square feet of space at any time after the first twelve months of the lease. 
Id. at 3.
The lease also contained a Disputes clause, FAR 52.233-1, which required, in part,
that “[a] claim by the Contractor shall be made in writing and, unless otherwise stated in this
contract, submitted within [six] years after accrual of the claim to the Contracting Officer for
a written decision.”  Exhibit 1 (SFO, General Clauses).
II. Events Leading To Dispute
In November 2011, GSA notified MDAD that the FDA would be vacating its portion
of the space under lease; 10,578 rentable square feet would be vacated immediately and 3525
rentable square feet would be vacated the following March.2  In March 2012, MDAD notified
GSA that the amount of space vacated by FDA was less than the amount set forth in GSA’s
notice.  Notice of Appeal (CBCA 6784), Claim at 2, Exhibit C).  Beginning in April 2012,
MDAD invoiced GSA for 40,140 useable square feet, including the space that it believed was
still occupied; GSA paid less than the amount invoiced, an amount calculated based upon
34,568 square feet.  Id., Claim at 2-3, Exhibit H.3
In August 2012, MDAD again emailed GSA to reiterate that the space vacated was
less than GSA stated and reported that a representative of one of the tenant agencies had
verified this information by conducting a walk-through of the space.  Exhibit 11b.  MDAD
asked whether GSA wanted to conduct a walk-through of the space prior to executing a
“supplemental agreement.”  Id.  In December 2014, the same tenant agency representative
walked the space with MDAD and “confirmed that the space vacated by the FDA was the
same as that indicated by MDAD since 2012.”  Notice of Appeal (CBCA 6784), Claim at 2;
Exhibit 16.
2 With this partial termination, the rentable square feet under the lease was
42,494 (56,597 - 14,103).  MDAD alleged in its claim that GSA’s notice was defective
because GSA did not provide the required 120-day notice.  With its notice, GSA properly
partially terminated the lease for 10,578 square feet immediately, as permitted by lease
paragraph 17, and terminated another 3525 square feet after 120 days, as permitted by lease
paragraph 4. 
3 The lease states the space under lease in both rentable and useable square feet,
with the useable square feet as the smaller amount.  While the parties used both terms and
figures in the course of the lease, the use of one figure over another is not material to the
dispute.

CBCA 6689, 6784 4
In October 2013, the parties executed lease amendment 2, with which the parties
sought to “increase 42,494 rentable square feet (34,548 ANSI/BOMA office area square feet)
to 44,310 rentable square feet (36,318 ANSI/BOMA office area square feet)” and increase
the annual rent amount.  Exhibit 3 at 1-2.  Thereafter, the parties executed a series of lease
amendments, which increased the annual rent and/or extended the lease term, but the rentable
square footage remained the same.  Exhibit 4 at 2 (SLA 3); Exhibit 5 (SLA 4); Exhibit 6
(SLA 5); Exhibit 7(SLA 6).  Despite these amendments, MDAD continued to invoice GSA
for amounts greater than GSA paid in rent.  Notice of Appeal (February 2020 Claim,
Exhibit H).
 
Before executing lease amendments 5 and 6 in March 2016, MDAD sent a letter to
the contracting officer, putting GSA on notice that the square footage amount set forth in
those proposed lease amendments was in dispute and reserving its rights to seek unpaid rent. 
Exhibit 18 at 1.  The contracting officer acknowledged the reservation with his signature on
MDAD’s notice, id., and the parties executed lease amendments 5 and 6.
In September 2017, the parties executed lease amendment 8, in which the useable
square feet figure was changed to 40,141, and the annual rent was set at $999,709.49, for the
period March 1, 2017, through February 28, 2019.  Exhibit 9.  According to MDAD, this
lease amendment resolved the discrepancy in the space under lease and the amount MDAD
invoiced GSA for rent matched the amount that GSA paid.  Notice of Appeal (Feb. 2020
Claim at 3).
In June 2019, MDAD submitted an uncertified claim to the contracting officer for the
difference between what it invoiced versus what GSA paid in rent from April 2012 through
February 2017.  The contracting officer issued a decision in August 2019, which MDAD
received in September 2019 and appealed on December 19, 2019 (docketed as CBCA 6689). 
Counsel for the parties, having identified the jurisdictional defect in the appeal, sought a stay
of the Board’s consideration of that appeal while MDAD submitted a properly certified claim
to the contracting officer on February 27, 2020.  Order (Jan. 9, 2020).  On March 31, the
contracting officer issued a decision denying the certified claim and MDAD filed its second
appeal on April 6, 2020 (docketed as CBCA 6784).
Discussion
I. The Board Lacks Jurisdiction In CBCA 6689
MDAD first appealed the contracting officer’s decision on its uncertified claim to the
Board.  “The contracting officer's decision on an uncertified claim is a nullity and may not
serve as a basis for Board jurisdiction.”  Hillcrest Aircraft Co. v. Department of Agriculture,

CBCA 6689, 6784 5
CBCA 2233, 11-1 BCA ¶ 34678 (citing Newport News Shipbuilding & Dry Dock Co. v.
Garrett, 6 F.3d 1547, 1552-53 (Fed. Cir. 1993)); Whiteriver Construction, Inc. v. Department
of the Interior, CBCA 2045, 10-2 BCA ¶ 34,582; 41 U.S.C. § 7103(b)(1), (f)(2)).  Although
GSA has not moved to dismiss this appeal, both parties acknowledged this jurisdictional
defect in proceedings before the Board and the Board sua sponte dismisses CBCA 6689 for
lack of jurisdiction.
II. The Six-Year Statute of Limitations Forecloses the Board’s Review of
MDAD’s Second Claim
The issue presented by GSA’s motion is when did MDAD’s claim accrue?  GSA
asserts that MDAD’s claims prior to the execution of lease amendment 2 are barred by the
six-year statute of limitations contained in the Contract Disputes Act (CDA).  We agree. 
However, we also find that, because MDAD’s claim accrued prior to February 27, 2014, the
Board’s consideration of MDAD’s entire claim is barred by the statute of limitations.4
Pursuant to the CDA and the lease at issue, “[e]ach claim by a contractor against the
Federal Government relating to a contract . . . shall be submitted within 6 years after accrual
of the claim.”  41 U.S.C. § 7103(a)(4); see 48 CFR 33.206(a) (“Contractor claims shall be
submitted, in writing, to the contracting officer for a decision within 6 years after accrual of
a claim, unless the contracting parties agreed to a shorter time period.”).  “Whether and when
a claim has accrued is determined according to the Federal Acquisition Regulation (FAR),
the language of the contract, and the facts of the particular case.”  Electric Boat Corp. v.
Secretary of the Navy, 958 F.3d 1372, 1375 (Fed. Cir. 2020).
The FAR defines claim accrual as “the date when all events that fix the alleged
liability on either the Government or the contractor and permit assertion of the claim, were
known or should have been known.  For liability to be fixed, some injury must have occurred. 
However, monetary damages need not have been incurred.”  48 CFR 33.201.  “[O]nce a party
is on notice that it has a potential claim, the limitations period begins to run.”  Thinkglobal,
Inc. v. Department of Commerce, CBCA 4410, 16-1 BCA ¶ 36,489 (quoting Cardinal
4 In its motion, GSA argues that the claims before lease amendment 2 are barred
by the six-year statute of limitations and the claims for amounts after the lease amendment
are barred by the terms of the lease amendment 2 and subsequent lease amendments. 
Respondent’s Motion at 9.  Because the statute of limitations forecloses our review of
MDAD’s entire claim, we do not reach this issue.  However, we do address MDAD’s
arguments in response to this argument as well as the statute of limitations argument. 
Appellant’s Opposition at 13-17.

CBCA 6689, 6784 6
Maintenance Service, Inc., ASBCA 56885, 11-1 BCA ¶ 34,616, at 170,610 (2010)).  “Claim
accrual does not depend on the degree of detail provided. . . . It is enough that the [party]
knows, or has reason to know, that some costs have been incurred, even if the amount is not
finalized or a fuller analysis will follow.”  Raytheon Co., Space & Airborne Systems, ASBCA
57801, et al., 13 BCA ¶ 35,319, at 173,377.
“A party’s failure to submit a claim within six years of accrual is an affirmative
defense to the claim.”  Thinkglobal, Inc.  GSA asserts statute of limitations as a defense to
MDAD’s claim, thus it bears the burden of proving MDAD’s claim is untimely.  Id. 
The legal basis for MDAD’s claim is that federal tenants continued to occupy space
in its building after GSA partially terminated its lease, space for which MDAD asserts it was
owed rent.  Beginning in April 2012, MDAD invoiced GSA but did not receive payment for
this additional space.  These facts, asserted in MDAD’s claim, establish that MDAD knew
the basis for its claim and suffered some injury more than six years prior to the submission
of its February 2020 claim.  On this basis, GSA has established that MDAD’s claim was
untimely.
 Lease Measurement Provision Does Not Establish a Pre-Claim Procedure.  MDAD
urges the Board to consider the contract provisions regarding measurement of the space and
find that GSA’s failure to comply with these provisions was a “mandatory pre-claim
procedure” that precluded the filing of a claim and precluded the running of the statute of
limitations.  Opposition at 10 (citing Kellogg Brown & Root Services Inc. v. Murphy, 823
F.3d 622, 628 (Fed. Cir. 2016)).  According to MDAD, GSA was obligated to measure the
space at MDAD’s request following the partial termination and the six-year statute of
limitations could not run until GSA measured the space (through a tenant agency
representative) in December 2014.
The measurement provision allows GSA to measure the space at the beginning of a
lease term to confirm that the lessor has been provided all the space offered in response to
the solicitation of offers.  The measurement provision incorporates a second provision
(provision number 27) of the SFO which discusses drawings provided by the lessor in
response to the solicitation and grants the contracting officer the right to decide whether to
measure the space.  This interpretation is logical since the lessor is a position to know the
space occupied in its building; GSA needs the right to measure to confirm.  Nothing in the
terms of the measurement provision suggests that GSA had an obligation to measure the
space or that the measurement of the space was a necessary pre-condition to MDAD’s ability
to file a claim.  Moreover, MDAD was able to invoice GSA beginning in April 2012 for the
difference in the rent; MDAD did not need GSA to measure the space to determine the
additional amount that it believed it was owed as a result of the continued use of the space.

CBCA 6689, 6784 7
MDAD’s Claim is Not a Continuing Claim.  MDAD also suggests that its claim is a
continuing claim and its claims within six years of the February 2020 claim survive. 
Opposition at 10 (citing JBG/Federal Center LLC v. General Services Administration,
CBCA 5506, 18-1 BCA ¶ 37,087).  “Where a claim is based upon a contractual obligation
of the Government to pay money, the claim first accrues on the date when the payment
becomes due and is wrongly withheld in breach of the contract.”  Id. (quoting Oceanic
Steamship Co. v. United States, 165 Ct. Cl. 217, 225 (1964)).  The continuing claim doctrine
does not assist MDAD in overcoming the statute of limitations.  MDAD’s claim arose when
federal tenants continued to occupy greater space. Unlike in JBG, where the government’s
obligation to pay taxes did not arise until the lessor presented a paid tax bill, here the space
did not change from 2012 and was reiterated in the bilateral amendment in 2013.  While GSA
had an obligation to pay rent monthly, in arrears, the space for which MDAD invoiced GSA
was fixed when the federal tenant failed to vacate all of the space identified in the notice of
termination.
No Basis for Equitable Tolling.  MDAD also asserts that the six-year limitation should
be equitably tolled because it had to wait for GSA to measure the space.  Opposition at 12. 
To establish a basis for equitable tolling, MDAD must establish that “(1) it has been pursuing
its rights diligently, and (2) that some extraordinary circumstances” prevented the timely
filing of its claim.  Pegasus Enterprises, LP v. General Services Administration, CBCA
5420, 19-1 BCA ¶ 37,459 (quoting Holland v. Florida, 560 U.S. 631, 649 (2010)).  As
already discussed, GSA was not required to measure the space before MDAD could submit
its claim.  MDAD has offered no other explanation as to why it could not submit a timely
claim; thus, there is no basis on which to equitably toll the statute of limitations.
Reservation of Rights Cannot Toll Statute of Limitations.  In response to GSA’s
arguments regarding the binding effect of lease amendments, MDAD provides evidence of
its reservation of rights prior to the execution of lease amendments 5 and 6.  While this
reservation may have precluded the enforcement of the terms of bilateral lease amendments
5 and 6 had MDAD filed a timely claim, it does not toll the six-year statute of limitations.
No Basis for Equitable Estoppel.  MDAD also asserts that GSA should be equitably
estopped from asserting the statute of limitations as a bar to its claims because it refused to
measure the space, despite MDAD’s requests that it do so, and it “unilaterally inserted”
square footage figures into the bilateral lease amendments executed by the parties. 
Appellant’s Opposition at 17.  MDAD has failed to show the “affirmative misconduct” on
the part of GSA, necessary for GSA to be estopped.  MLJ Brookside, LLC v. General
Services Administration, CBCA 4963, 15-1 BCA ¶ 36,166.  GSA was not obligated to
measure the space.  Moreover, GSA’s insertion of square footage amounts to which MDAD

CBCA 6689, 6784 8
registered an objection prior to execution of lease amendments 5 and 6 does not demonstrate
“affirmative misconduct.”
MDAD Did Not Assert Mistake in its Claim.  MDAD also asserts for the first time
that it made a unilateral mistake in “its reading of the square footage and rent in the SLAs.” 
Appellant’s Opposition at 16.  Each “claim” brought under the CDA must be submitted in
writing to the contracting officer, with adequate notice of the basis for the claim.  Strawberry
Hill, LLC v. General Services Administration, CBCA 5149, 16-1 BCA ¶ 36,561 (citing Santa
Fe Engineers, Inc. v. United States, 818 F.2d 856, 858 (Fed. Cir. 1987)).  An action brought
under the CDA “must be ‘based on the same claim previously presented to and denied by the
contracting officer.’”  Qwest Communications Co. v. General Services Administration,
CBCA 3423, 14-1 BCA ¶ 35,655 (citing Scott Timber Co. v. United States, 333 F.3d 1358,
1365 (Fed. Cir. 2003)).  “It must arise from the same operative facts and claim essentially the
same relief.”  Id.; see EHR Doctors, Inc. v. Social Security Administration, CBCA 3522, 14-1
BCA ¶ 35,630.  MDAD did not allege unilateral mistake nor assert the facts necessary to
establish this defense in its claim to the CO.  Thus, the Board lacks jurisdiction over such a
claim and it cannot be the basis for a defense to GSA’s motion. 
Decision
CBCA 6689 is DISMISSED FOR LACK OF JURISDICTION.  GSA’s motion for
summary judgment in CBCA 6784 is granted and the appeal is DENIED.
