MOTION TO EXCLUDE TESTIMONY DENIED:  
June 4, 2015
CBCA 3350, 3672, 4658, 4659
YATES-DESBUILD JOINT VENTURE,
Appellant,
v.
DEPARTMENT OF STATE,
Respondent.
Douglas L. Patin and Thomas R. Lynch of Bradley Arant Boult Cummings LLP,
Washington, DC, counsel for Appellant.
Thomas D. Dinackus, Office of the Legal Adviser, Buildings and Acquisitions,
Department of State, Rosslyn, VA, counsel for Respondent.
LESTER, Board Judge.
Pending before the Board is appellant’s motion to exclude the testimony of the
Government’s scheduling expert, Mark Boe, from the upcoming hearing in these appeals. 
For the reasons set forth below, the motion to exclude is denied.
Background
These appeals involve a contract that respondent, the Department of State (DOS),
awarded to appellant, Yates-Desbuild Joint Venture (YDJV), in 2005 for the design and
construction of a compound for the United States Consulate in Mumbai, India.  Although the
contract required substantial completion of the construction of nine buildings in Mumbai by

CBCA 3350, 3672, 4658, 4659 2
March 18, 2008, the Government did not certify the project as substantially complete until
October 6, 2011.
On August 30, 2012, YDJV submitted a certified claim to the contracting officer,
through which it requested a time extension of 1184 days, 868 of which it considered
compensable.  In a decision dated February 21, 2013, the DOS contracting officer denied
YDJV’s requests for additional time and compensation and demanded payment of over $11
million in liquidated damages.  After YDJV appealed that decision to the Board, the DOS
contracting officer issued another decision demanding payment of additional monies, which
YDJV then appealed.  YDJV also appealed two more contracting officer decisions denying
additional monetary claims that YDJV had submitted.  Those appeals were all consolidated
and are now pending before the Board for hearing.
Both parties have indicated that, because of the nature of the construction contract at
issue here and the type of delays for which both YDJV and the Government are seeking
compensation, they will present testimony from expert witnesses in schedule delay analysis. 
On May 4, 2015, YDJV filed a motion to exclude the testimony of the Government’s
scheduling expert witness, Mark Boe, on two grounds.  First, YDJV asserts that Mr. Boe
should not be permitted to express any opinions on the Mumbai building permit process
because he is not qualified to express such opinions.  Second, YDJV asks the Board to
exclude Mr. Boe’s scheduling opinions in total, as well as the entirety of his expert report,
because his methodology is flawed and not recognized in the industry.
Discussion
I. The Standard for Excluding Expert Testimony
The purpose of a motion in limine is “to prevent a party before trial from encumbering
a record with irrelevant, immaterial, or cumulative matters.”  J.R. Roberts Corp., DOT BCA
2499, 94-2 BCA ¶ 26,645, at 132,558 (quoting Baskett v. United States, 2 Cl. Ct. 356, 367-68
(1983)); see Palmerin v. City of Riverdale, 794 F.2d 1409, 1413 (9th Cir. 1986) (“Pretrial
motions are useful tools to resolve issues which would otherwise ‘clutter up’ the trial.”). 
“Such a motion enables a [tribunal] to rule in advance on the admissibility of documentary
or testimonial evidence and thus expedite and render efficient a subsequent trial.”  J.R.
Roberts, 94-2 BCA at 132,558 (quoting Baskett, 2 Cl. Ct. at 368). 
The party seeking to exclude evidence on a motion in limine has the burden of
demonstrating that “the evidence sought to be excluded is clearly inadmissible for any
purpose.”  Technical Systems Associates, Inc. v. Department of Commerce, GSBCA
13277-COM, et al., 98-2 BCA ¶ 30,066, at 148,770; see Peter Kiewit Sons’ Co., IBCA

CBCA 3350, 3672, 4658, 4659 3
3535-95, et al., 00-2 BCA ¶ 31,044, at 153,303.  “Unless evidence meets this high standard,
evidentiary rulings should be deferred until trial so that questions of foundation, relevancy
and potential prejudice may be resolved in proper context.”  Hawthorne Partners v. AT&T
Technologies, Inc., 831 F. Supp. 1398, 1400 (N.D. Ill. 1993).
Pursuant to Federal Rule of Evidence 702, so long as “scientific, technical, or other
specialized knowledge will help the trier of fact to understand the evidence or to determine
a fact in issue,” a “witness who is qualified as an expert by knowledge, skill, experience,
training, or education may testify in the form of an opinion or otherwise.”  As the Supreme
Court established in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993),
and Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999), “reliability is the touchstone for
expert testimony on ‘scientific, technical, or other specialized knowledge.’”  Libas, Ltd. v.
United States, 193 F.3d 1361, 1366 (Fed. Cir. 1999).  Although the Board’s rules “are more
flexible than the Federal Rules when it comes to the admissibility of evidence,” an expert’s
opinion, even before the Board, “must be credible.”  Universal Yacht Services, Inc., ASBCA
53951, 04-2 BCA ¶ 32,648, at 161,578-79 (discussing comparable Armed Services Board
of Contract Appeals rule).  “[T]o be credible, expert opinion must be reliable,” and, “to be
reliable, it must meet the same standards set forth for the admissibility of expert testimony”
in the Federal Rules.  Id. at 161,579.
In applying the evidentiary standards of Daubert and Kumho Tire, “[a] trial judge has
a ‘gatekeeping role’ to screen proposed expert evidence for reliability and relevance.”  Peter
Kiewit, 00-2 BCA at 153,303 (citing Daubert, 509 U.S. at 589, 597).  Expert witness
“‘knowledge’ connotes more than subjective belief or unsupported speculation.”  Daubert,
509 U.S. at 590.  “Proposed [expert] testimony must be supported by appropriate
validation – i.e., ‘good grounds,’ based on what is known.”  Id.  Accordingly, in evaluating
a motion to exclude a particular individual’s expert testimony from consideration, the Board
“ha[s] to decide whether [that] particular expert ha[s] sufficient specialized knowledge to
assist the [tribunal] ‘in deciding the particular issues in the case.’”  Kumho Tire, 526 U.S. at
156 (quoting 4 J. McLaughlin, Weinstein’s Federal Evidence ¶ 702.05[1], at 702-33 (2d ed.
1998)).
Nevertheless, “a trial judge’s inquiry is a flexible one, and the judge is accorded broad
latitude in determining the reliability of, and whether to admit or exclude, expert evidence.” 
Peter Kiewit, 00-2 BCA at 153,303 (citation omitted); see Yamaha International Corp. v.
Hoshino Gakki Co., 840 F.2d 1572, 1582 (Fed. Cir. 1988) (tribunal has “broad discretion to
admit the testimony of . . . experts”).  Further, the concerns about reliability and relevance
that the Supreme Court addressed in Daubert and Kumho Tire, while still a necessary inquiry
in cases before the Board, “are of lesser import in a bench trial” than in a jury trial, Seaboard
Lumber Co. v. United States, 308 F.3d 1283, 1302 (Fed. Cir. 2002), “because the [judge in

CBCA 3350, 3672, 4658, 4659 4
a bench trial] is better equipped than a jury to weigh the probative value of expert evidence.” 
Traxys North America, LLC v. Concept Mining, Inc., 808 F. Supp. 2d 851, 853 (W.D. Va.
2011).  “There is less need for the gatekeeper to keep the gate when the gatekeeper is keeping
the gate only for himself.”  United States v. Brown, 415 F.3d 1257, 1269 (11th Cir. 2005). 
“[W]here the factfinder and the gatekeeper are the same, the [tribunal] does not err in
admitting the evidence subject to the ability later to exclude it or disregard it if it turns out
not to meet the standard of reliability established by [Federal] Rule [of Evidence] 702.”  In
re Salem, 465 F.3d 767, 777 (7th Cir. 2006).  Our hearing in these appeals, as in all of our
cases, will be heard by a judge alone, without a jury.
With these standards in mind, we consider the two grounds upon which YDJV has
asked us to exclude Mr. Boe’s expert testimony and report.
II. Mr. Boe’s Testimony Regarding the Permitting Process
Pursuant to Federal Rule of Evidence 702, a witness who provides expert testimony
must be “qualified by knowledge, skill, experience, training, or education” to present that
testimony, although tribunals interpret “Rule 702’s qualification requirement liberally.” 
Pineda v. Ford Motor Co., 520 F.3d 237, 244 (3d Cir. 2008).  YDJV complains that Mr. Boe
should not be permitted to testify about the Mumbai building permit process as part of his
schedule analysis because he lacks any qualifications to opine upon that subject.
In response, the Government acknowledges that Mr. Boe does “not consider [himself]
an expert in any aspect of permitting in Mumbai.”  Declaration of Mark Boe ¶ 5 (May 15,
2015).  Nevertheless, the Government asserts that Mr. Boe is not being proferred as an expert
on the permitting process.  Instead, it asserts, it is offering Mr. Boe to testify about the impact
of the permitting process performance of the project at issue in this case and the contractual
delays that accompanied it.  The Government further asserts that YDJV’s own expert,
Charles V. Choyce, Jr., similarly relies on the permitting process in his own schedule
analysis, even though he, too, lacks expertise in that process, and it argues that, if the Board
excludes any testimony from Mr. Boe that touches upon the permitting process, it must
similarly exclude such testimony from Mr. Choyce. 
The Board will not preclude Mr. Boe from presenting a schedule analysis that includes
a discussion of the effect of the permitting process upon the project.  Under Federal Rule of
Evidence 703, “[a]n expert may base an opinion on facts or data in the case that the expert
has been made aware of.”  Some of those facts may be ones that counsel for a party has asked
the expert to assume are true, and counsel may plan to establish the validity of those factual
assumptions elsewhere in the case through other evidence, witnesses, or inferences.  See
Williams v. Illinois, 132 S. Ct. 2221, 2228 (2012) (plurality opinion) (“Under settled evidence

CBCA 3350, 3672, 4658, 4659 5
law, an expert may express an opinion that is based on facts that the expert assumes, but does
not know, to be true.”); see also Childress v. Ozark Delivery of Missouri L.L.C., No. 09-CV-
3313, 2014 WL 7181038, at *2 (W.D. Mo. Dec. 16, 2014) (“The language used in Rule 702
is ‘broad enough to allow an expert to rely on hypothetical facts that are supported by the
evidence.’” (quoting Fed. R. Evid. 702 Advisory Committee Notes, 2000 Amendment));
Richman v. Sheahan, 415 F. Supp. 2d 929, 942 (N.D. Ill. 2006) (“Experts routinely base their
opinions on assumptions that are necessarily at odds with their adversary’s view of the
evidence.”).  This may be particularly true in construction delay cases, which can require a
complex scheduling analysis in which a scheduling expert may have to identify and isolate
the various interrelated subprojects necessary for full contract performance and completion,
identify a baseline schedule by which these interrelated subprojects would have been
performed had no delays occurred, evaluate how changes and delays on one subproject
impacted the contractor’s ability to commence or complete performance of other subprojects,
assess the impact of each of the various delays (taken individually and in totality) upon the
contractor’s ability timely to complete performance, assess the extent of that impact
throughout the contract performance period, and attempt to assign responsibility for and
quantify the various delays.  See, e.g., Haney v. United States, 676 F.2d 584, 595 (Ct. Cl.
1982) (discussing requirements of critical path schedule analysis); Mega Construction Co.
v. United States, 29 Fed. Cl. 396, 425 (1993) (same); J. Richard Margulies, “Delays,
Suspension of Work, and Acceleration,” in Construction Contracting 617, 662-67 (1991)
(same).
It is highly unlikely that a scheduling expert would have expertise in every single
underlying cause of delay on a construction project, and there would be, at most, a tiny pool
of expert witnesses who would be available to assist parties in construction delay cases if
such broad expertise were necessary.  Thankfully, in creating a schedule delay analysis, the
testifying expert does not necessarily need to have such specific expertise in every cause of
delay.  As long as the testifying witness has expertise in scheduling analysis itself, he can rely
upon factual assumptions provided to him or upon opinions of other experts to address
technical causes of delay that he himself cannot address.  See Williams, 132 S. Ct. at 2228. 
If the expert assumes facts or relies upon other expert opinions that ultimately are not proven
or are found to be unreliable, it may very well affect the viability of the expert’s opinions in
the case.  But the Board will not preclude a party from presenting a complete schedule
analysis showing the impact of various delays, from an expert qualified in scheduling
techniques and analysis, simply because the expert, for lack of expertise on the technical
elements underlying the cause of a particular delay, must assume facts associated with the
cause of that delay – facts that the party presenting the expert analysis may ultimately prove
through other means.

CBCA 3350, 3672, 4658, 4659 6
In this particular case, the Government has represented that Mr. Boe will not be
testifying as an expert on the Mumbai building permit process, and we can find nothing in
YDJV’s briefing establishing that, in conducting his schedule analysis, Mr. Boe stepped
outside his role as an expert in scheduling analysis.  YDJV’s own expert, Mr. Choyce,
discusses the permitting process in his report, and he appears to reach opinions about YDJV’s
original expectations of that process – that “YDJV reasonably assumed no significant
impediments that would prevent ‘fast track’ construction,” among others – and the impact
of the permitting process, as it actually happened, on the design and construction process. 
In his deposition transcript, Mr. Choyce, like Mr. Boe, disclaims any expertise in
international permit processes.  See Transcript of Deposition of Charles V. Choyce, Jr., at 46
(Mar. 24, 2015).  Given the seeming similarity of the manner in which both parties’
scheduling experts have evaluated the permitting process in their expert reports, we cannot
see any basis for excluding this aspect of Mr. Boe’s, but not Mr. Choyce’s, opinions.  To the
extent that, during the hearing of this matter, YDJV believes that Mr. Boe is improperly
providing a permit process opinion beyond his area of expertise, it can raise an objection at
that time.
III. Mr. Boe’s Schedule Analysis
YDJV next complains that Mr. Boe should not be allowed to present any of his
schedule analysis, and that the Board should exclude the entirety of his expert report, because 
Mr. Boe’s methodology is flawed and is not recognized in the industry.  YDJV asserts that,
in his report, Mr. Boe states that he has used a methodology supported by the Association for
the Advancement of Cost Engineers International Recommended Practice for Forensic
Schedule Analysis (RP), RP 29R-03, but that, in reality, his analysis is inconsistent with the
RP.  The Government, in response, argues that RP 29R-03 indicates that “[f]orensic schedule
analysis . . . is both a science and an art” and that Mr. Boe’s analysis fully complies with that
RP.
YDJV’s objections to Mr. Boe’s methodology and analysis seem better resolved at a
hearing on the merits than on a motion to exclude the entirety of the Government’s schedule
analysis.  “Vigorous cross-examination, presentation of contrary evidence, and careful
instruction on the burden of proof are the traditional and appropriate means of attacking
shaky but admissible evidence.”  Daubert, 509 U.S. at 596.  Here, both the Government’s
and YDJV’s experts plan to present detailed and complex analyses evidencing the results of
their study of documentation associated with the scheduling of this construction project.  We
believe that these competing expert analyses as to the impact of schedule delays “will help
the trier of fact to understand the evidence or to determine a fact in issue.”  Fed. R. Evid. 702. 
YDJV can draw attention to any deficiencies in Mr. Boe’s analysis and opinions through
targeted cross-examination and through the presentation of Mr. Choyce’s testimony, which

CBCA 3350, 3672, 4658, 4659 7
will provide a better record for challenging Mr. Boe’s opinions than currently exists.  In light
of our broad discretion to permit expert testimony, see Peter Kiewit, 00-2 BCA at 153,303,
our desire for a full record in support of each party’s positions, and the non-jury nature of a
proceeding before the Board, we deny YDJV’s request that we exclude Mr. Boe’s schedule
analysis.  To the extent that, during the development of testimony at the hearing of these
appeals, YDJV believes that there is additional support for its motion, it may request
alteration of the Board’s in limine ruling at that time.  See Luce v. United States, 469 U.S. 38,
41 (1984) (in limine rulings may be altered at trial).
Decision
YDJV’s motion in limine to exclude Mr. Boe’s testimony is DENIED.
