8 Plaintiff, ORDER ON DAUBERT MOTIONS 9 v. Re: Dkt. Nos. 203, 204, 206, 207, 208, 209,

10 AECOM TECHNICAL SERVICES, INC., 210 11 Defendant.

12 13 Before the Court are various motions to exclude expert opinions and testimony brought by 14 both JH Kelly LLC (“JH Kelly”) and Defendant and Counter-Claimant AECOM Technical 15 Services, Inc. (“AECOM”). Considering the significant number of disputes both parties have 16 raised in this case generally and in these motions specifically, the Court will endeavor to provide 17 succinct rulings on these motions as described below. The general theme is that the parties’ 18 motions mostly function as previews of their cross-examinations, and are largely based on issues 19 that go to the weight the jury should assign the expert testimony instead of whether it is 20 admissible. Most of them are accordingly denied. 22 This construction dispute arises out of the Burney K2 Replacement Project (“Project”), 23 which involved the replacement of a natural gas compressor unit and various upgrades at a 24 compressor station near Burney, California. Dkt. No. 102 (JH Kelly’s Second Amended 25 Complaint or “SAC”) ¶ 1. The Burney Compressor Station is part of Pacific Gas & Electric 26 Company’s (“PG&E”) natural gas distribution system. Id. ¶ 11. That system supplies natural gas 27 to the surrounding area and allows compressed gas to travel through pipelines from Oregon to 1 million customers from Bakersfield, California to the Oregon border. Id. 2 On February 11, 2016, AECOM entered into an agreement (the “EPC Agreement”) with 3 PG&E for the Project. Id. ¶ 19. Under the EPC Agreement, AECOM agreed to act as the design- 4 builder and prime contractor for the Project. Id. On October 21, 2016, AECOM and JH Kelly 5 entered into an agreement (the “Subcontract”) for the construction portion of the work. Id. ¶¶ 25- 6 27. 7 Various issues on the Project led to disputes between JH Kelly, AECOM and PG&E. 8 Relevant here, JH Kelly contends that the Project was changed from what it bid and agreed to 9 perform, and that these changes imposed significant additional work and more difficult working 10 conditions. See Dkt. No. 162 (“Joint Pretrial Statement”). JH Kelly also asserts that AECOM 11 repeatedly ignored the Subcontract’s change-order requirements to pay JH Kelly for the changed 12 work. Id. AECOM denies each of those claims and counterclaims that JH Kelly breached the 13 Subcontract. Id. 14 JH Kelly filed the First Amended Complaint in January 2021. Dkt. No. 18. AECOM and 15 PG&E reached a settlement in October 2021 and ultimately agreed to dismiss their claims against 16 one another with prejudice. See Dkt. Nos. 93, 127. JH Kelly then filed the operative complaint, 17 which AECOM moved to dismiss in part. Dkt. No. 102. AECOM’s motion was granted in part 18 and denied in part. Dkt. No. 179. 20 A. Rules 26 and 37 21 Federal Rule of Civil Procedure 26 provides that a party must, without awaiting a 22 discovery request, provide to the other parties: 23 (i) the name and, if known, the address and telephone number of 24 each individual likely to have discoverable information— along with the subjects of that information—that the 25 disclosing party may use to support its claims or defenses, unless the use would be solely for impeachment; 26 (ii) a copy—or a description by category and location—of all 27 documents, electronically stored information, and tangible the use would be solely for impeachment. 1 Fed. R. Civ. P. 26(a). 2 Rule 26(e), in turn, provides the framework under which a party may supplement those 3 initial disclosures. Specifically, it states that a party who has made an initial disclosure, or who 4 has responded to an interrogatory, request for production, or request for admission, “must 5 supplement or correct its disclosure or response in a timely manner if the party learns that in some 6 material respect the disclosure or response is incomplete or incorrect, and if the additional or 7 corrective information has not otherwise been made known to the other parties during the 8 discovery process or in writing.” Fed. R. Civ. P. 26(e). 9 And finally, Rule 37(c)(1) provides: “If a party fails to provide information or identify a 10 witness as required by Rule 26(a) or (e), the party is not allowed to use that information or witness 11 to supply evidence on a motion, at a hearing, or at a trial, unless the failure was substantially 12 justified or is harmless.” In addition, or instead, the court may also impose other appropriate 13 sanctions provided for in Rule 37. See Fed. R. Civ. P. 37(c)(1)(A)-(C). “The party facing 14 sanctions bears the burden of proving that its failure to disclose the required information was 15 substantially justified or is harmless.” R & R Sails, Inc. v. Ins. Co. of Pa., 673 F.3d 1240, 1246 16 (9th Cir. 2012). 17 B. Rules 402 and 403 18 The Court has broad discretion to manage the conduct of a trial and the evidence presented 19 by the parties. Navellier v. Sletten, 262 F.3d 923, 941-42 (9th Cir. 2001). “To be admissible, 20 evidence must be relevant under Fed. R. Evid. 402 and its probative value must not be 21 substantially outweighed by the danger of unfair prejudice under Fed. R. Evid. 403.” Hangarter v. 22 Provident Life & Acc. Ins. Co., 373 F.3d 998, 1019 (9th Cir. 2004). 23 Under Federal Rule of Evidence 401, evidence is relevant if: (a) it has any tendency to 24 make a fact more or less probable than it would be without the evidence; and (b) the fact is of 25 consequence in determining the action. Fed. R. Evid. 401. And under Federal Rule of Evidence 26 403, and as is true with all evidence, the Court must consider whether the probative value of 27 proffered evidence “is substantially outweighed by a danger of one or more of the following: 1 unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or 2 needlessly presenting cumulative evidence.” Fed. R. Evid. 403. The Federal Rules of Evidence 3 confer “broad discretion on the trial judge to exclude evidence on any of the grounds specified in 4 Rule 403.” United States v. Hearst, 563 F.2d 1331, 1349 (9th Cir. 1977); see also United States v. 5 Olano, 62 F.3d 1180, 1204 (9th Cir. 1995) (“trial courts have very broad discretion in applying 6 Rule 403”) (citations omitted). 7 C. Rule 702 8 Federal Rule of Evidence 702 allows a qualified expert to testify “in the form of an opinion 9 or otherwise” where: (a) the expert’s scientific, technical, or other specialized knowledge will help 10 the trier of fact to understand the evidence or to determine a fact in issue; (b) the testimony is 11 based on sufficient facts or data; (c) the testimony is the product of reliable principles and 12 methods; and (d) the expert has reliably applied the principles and methods to the facts of the case. 13 Fed. R. Evid. 702. Expert testimony is admissible under Rule 702 if the expert is qualified and if 14 the testimony is both relevant and reliable. See Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 15 579, 597 (1993); see also Hangarter, 373 F.3d 998, 1015 (9th Cir. 2004). Rule 702 contemplates 16 a “broad conception of expert qualifications.” Hangarter, 373 F.3d at 1018 (emphasis in original). 17 Courts consider a purported expert’s knowledge, skill, experience, training, and education 18 in the subject matter of his asserted expertise. United States v. Hankey, 203 F.3d 1160, 1168 (9th 19 Cir. 2000); see also Fed. R. Evid. 702. Relevance, in turn “means that the evidence will assist the 20 trier of fact to understand or determine a fact in issue.” Cooper v. Brown, 510 F.3d 870, 942 (9th 21 Cir. 2007); see also Primiano v. Cook, 598 F.3d 558, 564 (9th Cir. 2010) (“The requirement that 22 the opinion testimony assist the trier of fact goes primarily to relevance.”) (quotation omitted). 23 Under the reliability requirement, the expert testimony must have a “reliable basis in the 24 knowledge and experience of the relevant discipline.” Primiano, 598 F.3d at 565. To ensure 25 reliability, the Court “assess[es] the [expert’s] reasoning or methodology, using as appropriate 26 such criteria as testability, publication in peer reviewed literature, and general acceptance.” Id. at 27 564. III. DISCUSSION 1 A. AECOM’s Daubert Motions 2 i. AECOM’s Motion to Exclude Testimony of Greg McKinnon (Dkt. No. 203) 3 JH Kelly retained a forensic accountant, Mr. Greg A. McKinnon, to opine on the “Project 4 budgets and costs of AECOM and PG&E and progress billings and payments between AECOM 5 and PG&E and Kelly and AECOM.” See Dkt. No. 203, Declaration of Luke Eaton ISO 6 AECOM’s Motion to Exclude Testimony of Greg McKinnon, Ex. 1 (“McKinnon Report”) ¶ 5. 7 Mr. McKinnon’s assignment was “limited to review and analysis of the billing and payment 8 record in order to calculate that part of the Subcontract balance” that AECOM owed JH Kelly, 9 based on payments received from PG&E. Id. ¶ 14. Mr. McKinnon opined that this amount is 10 $6,265, 276. Id. He was also asked “to determine where AECOM and PG&E cost overruns 11 occurred and to compare design cost overruns to construction cost overruns,” and he opined that 12 AECOM had “significant” cost overruns for the Project. Id. ¶ 15. 13 AECOM first contends that Mr. McKinnon should not testify before the jury because his 14 analysis is solely related to JH Kelly’s prompt payment claim, which was bifurcated and will be 15 decided by the Court. Dkt. No. 203 at 1. It then argues that Mr. McKinnon’s testimony would 16 invite the jury to infer that design cost overruns on the Project caused construction cost overruns 17 without a factual basis for doing so. Id. As explained below, the Court will not preclude Mr. 18 McKinnon from testifying for either reason. 19 The Court begins with AECOM’s first argument. The parties stipulated that the Court will 20 determine JH Kelly’s prompt payment claim and its request for litigation costs, attorney fees, and 21 interest after the jury has rendered a verdict. See Dkt. No. 147. AECOM contends that Mr. 22 McKinnon’s report “almost exclusively relates to the bifurcated prompt payment claim” and 23 therefore is irrelevant and should be excluded. Dkt. No. 203 at 2. In response, JH Kelly argues 24 that Mr. McKinnon’s testimony about the flow of payments from PG&E to AECOM and down to 25 JH Kelly is directly relevant to its breach of contract claim. Dkt. No. 222 at 6. 26 JH Kelly’s prompt payment claim and breach of contract claim have some overlap, since 27 JH Kelly ultimately argues that AECOM breached the Subcontract and violated California’s 1 prompt payment laws by failing to timely pay amounts owed to JH Kelly. See Joint Pretrial 2 Statement at 2. Mr. McKinnon’s testimony on the flow of payments therefore bears some 3 relevance to both claims. And as to the helpfulness of Mr. McKinnon’s testimony under Rule 4 702(a), the Court finds that Mr. McKinnon’s expertise in construction accounting can help the jury 5 track the complicated billings between the parties to the EPC agreement and Subcontract. 6 AECOM also argues that Mr. McKinnon’s opinions on the relationship between design 7 cost overruns on the Project and construction cost overruns are not proper expert opinions because 8 they are not based on any forensic accounting analysis. Mot. at 6. But AECOM’s challenge bears 9 on the weight of the expert’s testimony as opposed to its admissibility. After reviewing Mr. 10 McKinnon’s report, the Court finds that his analysis of AECOM’s cost overruns, when viewed as 11 a whole, is sufficiently based on his analysis of the billings at issue and his experience in 12 accounting, auditing, and analyzing costs related to construction projects to be admissible under 13 Rule 702. And as to the risk of unfair prejudice under Rule 403, the probative value of Mr. 14 McKinnon’s analysis is not substantially outweighed by the risks of unfair prejudice, undue delay, 15 or any other Rule 403 concern. To the extent AECOM fears the jury will assign undue weight to 16 Mr. McKinnon’s causal analysis (or lack thereof) between design and construction costs, it will 17 have every opportunity to undermine that testimony through effective cross-examination. Mr. 18 McKinnon will testify and, after AECOM’s cross-examination, the jury will decide how much 19 weight to give the testimony. Primiano v. Cook, 598 F.3d 558, 566 (9th Cir. 2010) (where the 20 foundation is sufficient, the litigant is entitled to have the jury decide upon the experts’ credibility, 21 rather than the judge). AECOM’s motion is DENIED. 22 ii. AECOM’s Motion to Exclude Testimony of Gerald Zamiski (Dkt. No. 204) 23 JH Kelly intends to offer Dr. Gerald Zamiski to provide expert testimony in support of its 24 defense to an AECOM counterclaim that seeks reimbursement for the replacement of a leaking gas 25 valve on the Project known as “GOV-2.” Dr. Zamiski’s assignment was to determine if sufficient 26 evidence exists to conclude (1) what caused the minor GOV-2 valve seat leakage, (2) what or who 27 is responsible for the minor GOV-2 valve seat leakage, or (3) whether the GOV-2 valve is 1 Fowler ISO Motion to Exclude Testimony of Gerald Zamiski, Ex. A (“Zamiski Report”) at 1. Dr. 2 Zamiski concluded that (1) there is no evidence sufficient to conclude with a reasonable degree of 3 engineering certainty what caused the GOV-2 valve leak; (2) it is not possible to determine who or 4 what is responsible for the GOV-2 valve leak; and (3) the GOV-2 valve is “functional” and does 5 not require replacement. See id. at 15-18. AECOM’s motion seeks to preclude Dr. Zamiski from 6 testifying based on four categories of arguments, which the Court briefly addresses below. 7 AECOM’s first major argument is that Dr. Zamiski’s opinion will not be helpful to the jury 8 and is not premised on reliable methods because it is not based on visual inspection or laboratory 9 analysis of the GOV-2 valve and is instead simply based on his review of the evidentiary record. 10 Dkt. No. 204 at 12. 11 The Court disagrees. AECOM is right that Dr. Zamiski did not conduct a laboratory test or 12 inspection to determine the root cause of the GOV-2 valve leak. As Dr. Zamiski explains in his 13 report, he could not do so because PG&E decided to leave the valve in use underground, making it 14 impossible for anyone to perform a visual examination or laboratory inspection. Zamiski Report 15 at 14. But in the Court’s view, that does not mean that Dr. Zamiski’s testimony is necessarily 16 unreliable or unhelpful under Rule 702. For one, just because Dr. Zamiski did not conduct 17 “laboratory testing” does not mean that he did not still use specialized knowledge and experience 18 to assess whether there is sufficient evidence of the root cause of the GOV-2 valve leak. Dr. 19 Zamiski was clear during his deposition that his expertise in material failure analysis requires and 20 generally allows him to determine the cause of failure of various types of components: 21 Q. As I understand it -- and you can tell me if I’m wrong. I don’t want 22 to mischaracterize this area of practice. But material failure analysis is when you kind of study a particular type of material and the stresses 23 that -- physical stresses or temperature stresses that that material experiences and how it reacts. Is that about right? 24 A. That’s one part of it. Sure. Basically, the bigger picture is as you 25 take a component, it’s got materials in it. You find out how it failed or what failed, and then you determine is it cracking, is it wear, is it 26 corrosion, is it abrasion. I mean, there’s a whole list of things, corrosion -- so there’s a whole core of failure modes for materials 27 used in components. And that’s what I do. 1 Declaration of Eric A. Grasberger ISO JH Kelly LLC’s Opposition, Ex. 16 at 28-29. Even though 2 he did not conduct laboratory testing, Dr. Zamiski’s analysis of the GOV-2 valve leak still falls 3 within the broad scope of that expertise. Nor is it dispositive that Dr. Zamiski based his review on 4 a survey of the available evidentiary record rather than physical testing. As Judge Chhabria 5 explained, “[a] broad survey of the available evidence is neither unusual in expert testimony nor 6 necessarily inappropriate.” In re Roundup Prod. Liab. Litig., 390 F. Supp. 3d 1102, 1130 (N.D. 7 Cal. 2018) (citations omitted). And while AECOM argues that the jury could understand and 8 interpret the documents and testimonial evidence that Dr. Zamiski reviewed themselves, the Court 9 disagrees and finds Dr. Zamiski’s testimony on the cause of the GOV-2 valve leak and 10 responsibility for the valve leak to be sufficiently helpful and based on his experience and review 11 of the record to survive scrutiny under Rules 702 and 403. See Dkt. No. 204 at 13. 12 Second, AECOM argues that Dr. Zamiski’s opinion on the cause of the GOV-2 valve leak 13 is an improper opinion regarding whether AECOM satisfied its burden of proof and therefore 14 invades the province of the jury. Id. at 14. But while Dr. Zamiski’s opinion certainly embraces 15 the ultimate issue to be decided the jury, the Federal Rules of Evidence make clear that “[a]n 16 opinion is not objectionable just because it embraces an ultimate issue.” Fed. R. Evid. 704(a); see 17 also Hangarter v. Provident Life & Acc. Ins. Co., 373 F.3d 998, 1016 (9th Cir. 2004) (“It is well- 18 established that expert testimony concerning an ultimate issue is not per se improper.”) (citations 19 omitted and cleaned up). Of course, an expert witness cannot give an opinion as to her legal 20 conclusion. See id. But Dr. Zamiski does not do that. His opinion that there was not sufficient 21 evidence to conclude what caused the GOV-2 valve leak or who was responsible for doing so goes 22 to factual causation, and it is admissible. 23 Third, AECOM challenges Dr. Zamiski’s opinion that there is no physical or other 24 evidence sufficient to conclude with a reasonable degree of engineering certainty that the GOV-2 25 valve requires replacement. Dkt. No. 204 at 15. To begin, AECOM reprises its argument that Dr. 26 Zamiski’s opinion should be excluded because he conducted no independent analysis and because 27 it is an improper legal conclusion. Id. at 16. These are the same arguments AECOM made about 1 More substantively, AECOM argues that although there is no dispute that Dr. Zamiski is 2 qualified to opine on issues related to mechanical or material failure analysis, the question of 3 whether the GOV-2 valve must be replaced implicates important considerations that fall outside 4 Dr. Zamiski’s expertise. Id. at 16-17. While that question requires a detailed understanding of 5 PG&E’s operations and industry, AECOM contends, Dr. Zamiski is not privy to PG&E’s 6 maintenance procedures, has not interviewed anyone from PG&E, and has no understanding of 7 PG&E’s business practices/considerations. Id. at 17. 8 The Court does not find Dr. Zamiski’s opinion on whether the GOV-2 valve requires 9 replacement helpful or adequately supported. Dr. Zamiski’s opinion that the GOV-2 valve is 10 “functional and does not require removal” is primarily based on his observation that PG&E has 11 decided to leave the valve in use since May 2018. See Zamiski Report at 18-19. This testimony 12 lacks the kind of specialized knowledge required by Rule 702(a), and the Court will not allow Dr. 13 Zamiski to put the imprimatur of his expertise on it. See White v. Ford Motor Co., 312 F.3d 998, 14 1008-9 (9th Cir. 2002) (“A layman, which is what an expert witness is when testifying outside his 15 area of expertise, ought not to be anointed with ersatz authority as a court approved expert witness 16 for what is essentially a lay opinion.”). Dr. Zamiski may not testify that the GOV-2 valve is 17 “functional and does not require removal.” See Zamiski Report at 18-19. 18 And fourth, AECOM raises two procedural challenges to Dr. Zamiski’s opinion. First, 19 AECOM moves under Federal Rule of Civil Procedure 26 to prevent Dr. Zamiski from testifying 20 about the POV-166 back-charge, which is a separate counterclaim against JH Kelly for the 21 replacement costs of the POV-166 valve after PG&E discovered that the valve was damaged by 22 significant amounts of clay, sand, and other debris. Dkt. No. 204 at 18. And second, AECOM 23 argues that Dr. Zamiski must be prohibited from testifying at trial because JH Kelly improperly 24 redacted a series of hand-written notes that Dr. Zamiski allegedly considered when preparing his 25 rebuttal report. Id. at 19-21. JH Kelly contends that these challenges are overblown because JH 26 Kelly will not ask Dr. Zamiski to opine about the cause of the damage to POV-166, and the 27 “redactions” were comprised of comments made by JH Kelly’s counsel that Dr. Zamiski did not 1 The Court finds these disputes inconsequential. Because AECOM has failed to 2 adequately articulate how it suffered prejudice because of the challenged conduct in light of JH 3 Kelly’s explanations, the Court will not preclude Dr. Zamiski from testifying for either reason. 4 See Fed. R. Civ. P. 37(c)(1). To summarize, Dr. Zamiski may not testify that the GOV-2 valve is 5 “functional and does not require removal,” but AECOM’s motion is otherwise DENIED. 6 iii. AECOM’s Motion to Exclude Testimony of Dr. William Ibbs (Dkt. No. 206) 7 JH Kelly claims that it suffered loss of productivity damages because of AECOM’s 8 excessive changes to the Project. See Dkt. 102 ¶ 49. JH Kelly retained Dr. William Ibbs to 9 quantify the impact of those changes. To do so, Dr. Ibbs used four different methodologies for 10 measuring loss of productivity – (1) Measured Mile; (2) Ibbs Curve; (3) MCAA Factors and (4) 11 Modified Total Cost, as reflected below: 12 Damage Category 1 13 D&D 14 Quantification Method Damages

15 Measured Mile $ 8,465,712 16 IBBS Curves $ 8,806,423

17 MCAA Factors $ 8,524,734 18 Modified Total Cost $ 8,941,595 19 Average $ 8,709,616 20 21 See Declaration of Marion T. Hack ISO Motion to Exclude Testimony of Dr. Williams Ibbs 22 (“Hack Decl.”), Ex. 1 (“Ibbs 2021 Report”) ¶ 286. And he identified five categories of lost 23 productivity damages: (1) damages for the delay and disruption (“D&D”) that the craft labor 24 employed directly by JH Kelly suffered; (2) JH Kelly’s equipment D&D damages; (3) JH Kelly’s 25 staff D&D damages; (4) and JH Kelly’s subcontractor D&D damages. Id. ¶ 283. 26 AECOM contends that all of Dr. Ibbs’s damages calculations rely on unsubstantiated 27 speculation and subjective beliefs and thus run afoul of Rule 702. See Dkt. No. 206 at 7. 1 AECOM raises four categories of challenges, which the Court addresses below.1 The major theme 2 here is that while the Court agrees that some of AECOM’s criticisms of Dr. Ibbs’s analysis have 3 significant force, it will ultimately allow the jury to determine how much weight to assign his 4 opinions. 5 a. JH Kelly’s Subcontractor and Staff D&D Damages 6 AECOM first seeks to exclude Dr. Ibbs’s opinions on JH Kelly’s alleged subcontractor and 7 staff D&D costs. See Ibbs 2021 Report ¶ 255. AECOM primarily criticizes Dr. Ibbs for assuming 8 that it was responsible for 99.72% of JH Kelly’s staff and subcontractor cost overruns. Dkt. No. 9 206 at 10. Specifically, AECOM contends that Dr. Ibbs applied the same amount he quantified for 10 JH Kelly’s craft labor’s self-inflicted D&D (.28%) to also calculate JH Kelly’s staff and 11 subcontractor D&D—despite allegedly doing “absolutely no analysis” or investigation to confirm 12 that the staff or subcontractors experienced similar productivity impacts. Id. JH Kelly disputes 13 that Dr. Ibbs used the same self-inflicted loss figure to calculate both categories of D&D. See Dkt. 14 No.223 at 17 (“Based on the aforementioned calculation summary, AECOM’s complaint that Dr. 15 Ibbs assigned only .28% of the costs to Kelly and its subcontractors is simply not accurate.”). 16 The Court agrees with AECOM that Dr. Ibbs’s opinions about JH Kelly’s alleged 17 subcontractor and staff D&D costs appear to rest on a shaky foundation. At deposition, Dr. Ibbs 18 admitted that he could not particularize his analysis to JH Kelly’s subcontractors and therefore 19 applied the same self-inflicted loss figure: 20 Q. Well, Dr. Ibbs, you didn't do any actual calculation as to what -- 21 you didn't do any investigation as to what the subcontractors could have actually caused on their own, did you? 22 A.· I -- I -- I -- I didn't have that level of information. I used what 23 was self-inflicted problems for Kelly, and I applied that to the other subs. That was the best information that I had available. I 24 didn't have any other quantitative information that would allow me to particularize it to the subs beyond that. 25 Q. But you agree that, I mean, JH Kelly could have had a small 26

27 1 The Court finds AECOM’s challenge to Dr. Ibbs’s use of the modified total cost method moot in amount of problems, but their subs could have been terrible, right? I 1 mean, you just don't know, do you?

2 MR. GRASBERGER: Objection. Argumentative.

3 THE WITNESS: I used a method that I thought was the focus given the information that was available. A lot of these subs had fixed 4 price contracts and they wouldn't disclose or they're not going to disclose that type of information. So I did what I thought was a 5 reasonable -- provided what I thought was a reasonable estimate for the subs using the information that I had available. 6 7 Hack Decl. ¶ 5, Ex. 2 (“Ibbs Dep.”) at 144-145 (emphases added). Dr. Ibbs’s explanation for 8 assuming that AECOM was responsible for 99.72% of JH Kelly’s staff and subcontractor cost 9 overruns appears weak. His argument is essentially that he did so because he had no choice. But 10 in the end, the Court finds that AECOM’s assertion that Dr. Ibbs made an unsupported assumption 11 and therefore reached faulty conclusions bears on the weight of his testimony, not its 12 admissibility. See United States for Use & Benefit of Bergelectric Corp. v. Sauer, Inc., No. 5:18- 13 CV-00612-EJD, 2020 WL 470273, at *2 (N.D. Cal. Jan. 29, 2020) (“District courts within and 14 outside this district have often concluded that experts’ decisions about what data to use in their 15 analysis bear on the weight, not the admissibility, of expert testimony.”) (citations omitted and 16 cleaned up). Dr. Ibbs says that his decision to impute JH Kelly’s craft labor’s self-inflicted loss 17 figure to its subcontractors still provides for a “reasonable estimate,” and that judgment is based 18 on his extensive experience quantifying productivity loss. See Ibbs Dep. at 144-145; Ibbs Report ¶ 19 4. The Court accordingly finds that his opinion on JH Kelly’s alleged subcontractor and staff 20 D&D costs narrowly survives scrutiny under Rule 702. The probative value of the testimony is 21 also not substantially outweighed by the risk of unfair prejudice, undue delay, or any other Rule 22 403 consideration. To the extent AECOM fears the jury will assign undue weight to Dr. Ibbs’s 23 opinion, it will have every opportunity to undermine the testimony through vigorous cross- 24 examination. 25 b. Measured Mile Method 26 Second, AECOM argues that Dr. Ibbs has not reliably applied the “measured mile” method 27 of calculating loss of productivity damages. The measured mile method is a technique where an 1 difference. See United States of Am. for the Use of Salinas Constr., Inc. v. W. Sur. Co., No. 14- 2 1963 JLR, 2016 WL 3632487, at *3 (W.D. Wash. July 7, 2016) (citations omitted). The 3 assumption is that the difference between the labor or equipment hours in the unimpacted and 4 impacted work represents the loss to the contractor. Id. It is a recognized and accepted method of 5 calculating loss of productivity. Id. But as a matter of common sense, for the measured mile 6 method to work the impacted and unimpacted activities being compared must be reasonably 7 similar. As AECOM notes, Dr. Ibbs himself has written that “[t]he measured mile analysis 8 technique requires identical or substantially similar work for productivity comparisons. If the 9 affected work is unique, or if the contractor did not keep good contemporaneous records, no 10 measured mile may exist.” See Dkt. No. 206 at 11 (citing Daniel E. Toomey, Joshua S. Marks, 11 Dr. Tong Zhao, P.E. & J. Mark Dungan, Calculating Lost Labor Productivity: Is There a Better 12 Way?, THE CONSTRUCTION LAWYER, Spring 2015, at 6). 13 AECOM argues that Dr. Ibbs misapplies the measured mile method because he does not 14 compare identical or even reasonably similar work in his analysis. Id. Specifically, AECOM 15 contends that Dr. Ibbs calculated the disruption of one trade activity on the Project—main gas 16 piping—to be 36.1%, and then applied that calculation to all other scopes of work including one of 17 the largest trades, electrical work activity. Id. at 10-16. JH Kelly explains that Dr. Ibbs had no 18 choice but to use this approach because after an initial minimally-impacted time period (during 19 which the main gas piping work was performed), the entire project was so impacted that it became 20 “extremely difficult” to derive a measured mile for the other impacted work activities. Dkt. No. 21 223 at 18-21. 22 The Court again agrees with AECOM that Dr. Ibbs’s extrapolation of one type of work to 23 an entire project—particularly a project as broad as this one—warrants scrutiny. But as JH Kelly 24 notes, Judge Davila recently found that similar flaws in a construction expert’s loss of productivity 25 analysis “bear on the weight of [the expert’s] testimony not its admissibility.” United States for 26 Use & Benefit of Bergelectric Corp. v. Sauer, Inc., No. 5:18-CV-00612-EJD, 2020 WL 470273, at 27 *2 (N.D. Cal. Jan. 29, 2020) (“The alleged flaws in [expert]'s measured mile analysis . . . may be 1 agrees. See also id. at *2 (“District courts within and outside this district have often concluded 2 that experts’ decisions about what data to use in their analysis bear on the weight, not the 3 admissibility, of expert testimony.”). And as to the risk of unfair prejudice under Rule 403, the 4 probative value of Dr. Ibbs’s analysis is not substantially outweighed by the risk of unfair 5 prejudice, undue delay, or any other Rule 403 consideration. To the extent AECOM fears the jury 6 will assign undue weight to Dr. Ibbs’s extrapolation, it again will have every opportunity to 7 undermine the testimony through effective cross-examination. 8 c. Ibbs Curves Method 9 AECOM also challenges Dr. Ibbs’s use of the “Ibbs Curves” methodology to quantify 10 delays and disruption on the Project. Dkt. No. 206 at 17. Before ruling on those challenges, the 11 Court will briefly explain how this method works. Dr. Ibbs has a “database” of historical projects 12 that have experienced loss of productivity, which comes from research he has performed over the 13 past three decades. Ibbs 2021 Report ¶ 260. His research has essentially found that there is a 14 statistical relationship between (1) the amount and timing of changes to a project and (2) a 15 contractor’s loss of productivity from that project. Id. ¶¶ 260-64. As reflected below, the Ibbs 16 Curves method accordingly measures this relationship with three separate axes for the percentage 17 of change, the timing of those changes (separated by early, median, or late), and the percentage of 18 productivity loss: 19 20 21 22 23 24 25 26 27 1 litter me Meer lale otal Oreja ride odgelell Ce 3 = 20% 4 é 5 eel ||| 7 a0% | ot S 40% 9] fz = 10 3 ‘iss | cee! ll a Early Change 12 50% |_| —"—= Median Change -— eo

13 —t— Late Change PH | eee ee 15 16 Id. at 132. Dr. Ibbs classified the Project as a “late change” project and estimated JH Kelly’s 17

D&D damages to be $8,806,423. Id. | 266. Z 18 AECOM first contends that the Ibbs Curves method should be excluded because it has not 19 been endorsed by the industry and has not been peer-tested due to proprietary underlying data. 20 Dkt. No. 206 at 17. As evidence, AECOM relies on a 2007 academic paper where a commentator 21 said that the Ibbs Curves Method “has not yet been endorsed by the industry.” /d. (citations 22 omitted). But that was fifteen years ago. Dr. Ibbs declared under penalty of perjury that since 23 2007, his method has been published in “numerous peer-reviewed scientific journals,” has been 24 “tested and meets the standards of the reviewers and readers of those scientific journals,” and has a 25 “known” rate of error reported by way of the statistical standard deviation accompanying the 26 formulas he uses. See Dkt. No. 223-2, Declaration of Dr. William Ibbs ISO JH Kelly’s Opposition 27 to AECOM’s Daubert Motion ¥ 4. Based on this representation, the Court finds that there is 28

1 sufficient evidence that Dr. Ibbs’s analysis “has been tested in accordance with proper scientific 2 methodology, that the articles were subject to peer review, or that the theory is generally accepted 3 in the relevant (or any) scientific community.” See Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 4 137, 149-50 (1999). 5 AECOM also takes issue with the “subjective” nature of the Ibbs Curves method and cites 6 its own expert’s testimony for the proposition that the Ibbs Curves method is “not appropriate for 7 or used in dispute resolution engagements.” Dkt. No. 206 at 20. This challenge plainly goes to 8 the weight of the evidence. At trial, AECOM will be able to show why it believes the Ibbs Curves 9 is unreliable by questioning the underlying data, pointing out its proprietary nature, challenging 10 Dr. Ibbs’s assumptions, and putting on its own expert. 11 d. MCAA Factors 12 AECOM also challenges Dr. Ibbs’ Mechanical Contractors Association of American 13 (“MCAA”) factors analysis. Dkt. No. 206 at 21. This approach proceeds in two steps. First, there 14 are 16 factors recognized by mechanical industry observers as being harmful to labor productivity, 15 like crew size inefficiency, fatigue, or season and weather change. See Ibbs Report at 138. 16 Aligned against those factors are three degrees of severity: minor, average, and severe. Id. 17 MCAA factors analysis consists of matching an impact with the appropriate severity level and 18 applying that figure to labor hours to estimate project disruption. Id. ¶ 269. 19 AECOM relies on three out-of-circuit district court cases for the proposition that MCAA 20 factors analysis per se fails to satisfy Daubert standards. Dkt. No. 206 at 21. But AECOM may 21 have misread those cases. Two of them disprove AECOM’s point because they are post-trial cases 22 where the courts clearly allowed testimony on MCAA factors analysis. See N. Am. Mech., Inc. v. 23 Walsh Const. Co. II, LLC, 132 F. Supp. 3d 1064, 1081 (E.D. Wis. 2015) (allowing a witness to 24 testify about his MCAA factors analysis but ultimately declining to use that approach to calculate 25 damages because the witness failed to analyze the specific conditions of the project to arrive at an 26 appropriate inefficiency rate); Sunshine Const. & Eng'g, Inc. v. United States, 64 Fed. Cl. 346, 371 27 (2005) (defendant’s expert testimony demonstrated that the plaintiff’s expert’s MCAA factors 1 The third case concerned a Daubert motion, but that court clarified that it was not analyzing the 2 type of MCAA factors analysis that Dr. Ibbs undertook. See Trane US Inc. v. Yearout Serv., LLC, 3 No. 5:17-CV-42-MTT, 2019 WL 2553100, at *4 (M.D. Ga. June 20, 2019) (distinguishing the 4 sixteen-factor MCAA methodology used here from the MCAA methodology the expert before it 5 had used, and noting that several Board of Contract Appeals cases had approved the sixteen-factor 6 methodology). The Court accordingly finds no basis to conclude that MCAA factors analysis per 7 se fails to satisfy Daubert standards. 8 As to Dr. Ibbs’s application of the MCAA factors to this case, AECOM suggests that he 9 manipulated his analysis to arrive at a predetermined outcome. For instance, AECOM argues that 10 because Dr. Ibbs’s 2021 report has a lower calculation of loss of productivity labor hours than his 11 2019 report, he increased other MCAA factors “to support the ultimate damages claim by JH 12 Kelly.” Dkt. No. 206 at 22-23. And AECOM also criticizes Dr. Ibbs for basing approximately 13 half of his lost labor productivity hours on the “vague” logistics factor. Id. at 23. Again, this 14 challenge goes to the weight of the evidence, and it does not pose a risk of unfair prejudice. The 15 proper manner of demonstrating that Dr. Ibbs misapplied the MCAA factors is through “through 16 competing evidence and incisive cross-examination,” as the case AECOM cited reflects. Murray 17 v. S. Route Mar. SA, 870 F.3d 915, 925 (9th Cir. 2017) (citations omitted); see also Sunshine 18 Const., 64 Fed. Cl. at 371. 19 To summarize, AECOM’s motion is DENIED in its entirety. 20 B. JH Kelly’s Daubert Motions 21 i. JH Kelly’s Motion to Exclude Portions of Expert Testimony of Denise Martini (Dkt. No. 207) 22 Ms. Martini is a civil engineer who provides her clients with construction consulting 23 services, including advising on and analysis of project planning, management and controls, 24 construction delay and disruption claims, and the calculation of financial damages. See Dkt. No. 25 207-1, Declaration of Eric Grasberger ISO Daubert Motion, Ex. 1 (“Martini Report”). She was 26 originally retained as an expert witness by PG&E, but after the settlement between PG&E and 27 AECOM, AECOM retained her to help prosecute five PG&E counterclaims against JH Kelly. 1 Dkt. No. 218 at 2. On October 18, 2022, while still acting on behalf of PG&E, Ms. Martini 2 submitted a single expert report in this case. See generally Martini Report. As part of this report, 3 PG&E asked Ms. Martini to conduct an accounting of the damages associated with five PG&E 4 backcharge claims. See id. at 1-2. Ms. Martini opines that PG&E has incurred or will incur a total 5 cost of $1,382,576 to repair, replace, or complete discrete items of work on the Project. Id. at 2. 6 JH Kelly seeks to exclude Ms. Martini’s opinion on the overhead or “indirect” expenses 7 that PG&E has allegedly incurred in connection with damages for repair of the V-35 valve, the 8 POV-166 valve, and for other Project elements. See generally Dkt. No. 207. The crux of JH 9 Kelly’s argument is that Ms. Martini’s testimony is unhelpful because it merely reiterates 10 allegations made by PG&E without performing any independent analysis into whether the 11 allegations were accurate or reliable. Id. 12 The Court agrees with JH Kelly that Ms. Martini’s report is, at times, light on substance. 13 For example, Ms. Martini wrote that PG&E added “discrete overhead costs” to the “direct labor 14 costs” to arrive at its “total fully burdened labor cost,” and that an alternative to this approach is to 15 add a single 250% labor overhead to its labor cost. Martini Report at 6. But as far as analysis 16 goes, she merely wrote that “[b]oth of these practices are a reasonable way to capture the full cost 17 of labor to PG&E.” Id. She takes a similar approach when opining on the indirect expenses that 18 PG&E has allegedly incurred. See, e.g., id. at 7 (“PG&E employees charged time and other costs 19 related to this repair to a specific cost code for the POV-166 valve repair, which I understand is 20 consistent with PG&E practice and is, in my opinion, a reliable cost accounting procedure.”); id. 21 (“These amounts appear to be reasonable, based on the fact that the estimate from an external 22 contractor was substantially higher than the internal cost”). In short, the Court agrees with JH 23 Kelly that Ms. Martini has no basis to opine on the reasonableness of PG&E’s costs themselves or 24 whether AECOM is entitled to recover for them. 25 But as AECOM points out, JH Kelly’s argument for exclusion misrepresents the scope of 26 Ms. Martini’s opinion. AECOM engaged Ms. Martini only to confirm that PG&E’s costs were 27 supported by the underlying cost documentation and to issue an opinion on whether she believed 1 construction cost management. Dkt. No. 218 at 7. The Court will allow Ms. Martini to testify for 2 this limited purpose. Ms. Martini’s testimony on whether PG&E’s methodologies were 3 reasonable is sufficiently based on her review of the record and experience in construction cost 4 management to survive scrutiny under Rule 702. See, e.g., Martini Report at 5 (explaining that 5 Ms. Martini’s assessment of PG&E’s markups to determine whether they were reasonable and 6 consistent with industry practice included reviewing purchase orders, invoices, and other backup 7 provided by PG&E, and verifying that those costs are as reflected as having been incurred by 8 PG&E). While JH Kelly contends that Ms. Martini’s testimony creates a danger of misleading the 9 jury because her testimony is not supported by any independent evaluation or analysis, the Court 10 finds this criticism to raise questions that are more appropriately addressed through cross- 11 examination and competing evidence. See Primiano, 598 F.3d at 564-65 (“Shaky but admissible 12 evidence is to be attacked by cross examination, contrary evidence, and attention to the burden of 13 proof, not exclusion.”). JH Kelly’s motion is DENIED. 14 ii. JH Kelly’s Motion to Exclude Expert Testimony of Larry Smith (Dkt. No. 208) 15 JH Kelly alleges that AECOM directed it to undertake significant work not within the 16 originally subcontracted scope of work, including extensive pipe coating work. See SAC ¶ 42. JH 17 Kelly allegedly incurred $2,126,741 in costs doing this pipe coating work, has not been paid by 18 AECOM for it, and is now suing to recover those costs. Id. ¶ 43. 19 AECOM retained Mr. Larry Smith to opine on the limited issue of fusion bonded epoxy 20 (“FBE”) coated piping at the Project. See Dkt. No. 208-1, Declaration of Eric A. Grasberger ISO 21 Daubert Motion to Exclude Expert Testimony of Larry Smith, Ex. 1 (“Smith Report”) ¶ 5. JH 22 Kelly now seeks to preclude Mr. Smith from testifying on four separate grounds. As explained 23 below, the Court does not find any of them persuasive and will deny JH Kelly’s motion. 24 First, JH Kelly argues that Mr. Smith has no experience with and is not qualified to opine 25 on FBE-coated pipe issues, mostly because he testified at his deposition that he has not personally 26 performed “holiday testing” on FBE-coated pipes before. Dkt. No. 208 at 6.2 But Mr. Smith also 27 1 explained at his deposition that he has performed holiday testing before in general, and that the 2 process of holiday testing of coatings does not depend on the type of coating being used. See Dkt. 3 No. 219-3, Declaration of John H. Conrad ISO Opposition to JH Kelly's Motion to Exclude Expert 4 Testimony of Larry Smith, Ex. 2 (“Smith Dep”) at 115 (“Well, you know, a coating is a coating. It 5 doesn't matter if it's FBE, paint, or rubber or what. It’s the same principle. And I have done that 6 over and over again.”); see also Smith Report ¶ 88 (“My experience as a mechanical contractor 7 has enabled me to handle, install, and holiday test many feet of coated pipe.”). The Court finds 8 Mr. Smith’s testimony on FBE pipe coating and holiday testing to be sufficiently based on his 9 experience in the field of underground coated steel pipe installation and coating thickness to 10 survive scrutiny under Rule 702(a). JH Kelly is free to cross-examine Mr. Smith on whether his 11 experience with validating other construction materials and inspections is applicable here, and it 12 can explain to the jury in closing argument why Mr. Smith’s testimony lacks credibility and 13 should not be given weight. 14 Second, JH Kelly contends that all Mr. Smith’s opinions must be stricken under Rule 15 702(c) because he admitted after submitting his report that various sections of the appendix 16 contain duplicate holiday inputs. Dkt. No. 208 at 8. JH Kelly claims that Mr. Smith’s 17 acknowledgement of these errors demonstrates that his principles and methods are “undoubtedly 18 unreliable” and that the data he has produced is “grossly deficient and untrustworthy.” Id. 19 Adjectives aside, however, JH Kelly’s motion fails to explain how these errors, which AECOM 20 says were inadvertent, affect the substance of Mr. Smith’s opinions. The Court accordingly will 21 not preclude Mr. Smith from testifying on this ground. 22 Third, JH Kelly seeks to preclude Mr. Smith’s opinions on JH Kelly’s alleged mishandling 23 of FBE-coated pipe at the project site. Dkt. No. 208 at 8-9. To rebut Dr. Ibbs’s point that JH 24 Kelly’s field-coating was affected by wet and cold winter weather, Mr. Smith wrote in the 25 challenged paragraph that “[i]nspectors reported that incoming coated materials and field coated 26 materials were often unloaded by forklift, secured by chain instead of straps, stored on the ground 27 1 without soldiers, [and were] handled, stored and moved without protection for coatings,” and he 2 concluded that “[g]ood practices, in any weather, yield fewer field impacts to quality materials.” 3 Smith Report ¶ 67. 4 JH Kelly’s motion argues that Mr. Smith has failed to cite “specific project records” or any 5 admissible evidence to support his assertion that it mishandled any of the FBE-coated pipe. Dkt. 6 No. 208 at 8. But at Mr. Smith’s deposition, he clarified that his opinion was based on daily 7 reports from the Project and statements made by PG&E’s inspector, Mr. Kuns. See Smith Dep. at 8 170-71. Because Mr. Smith claims that he relied on project documents to support his opinion, the 9 Court finds that, at least at this stage, AECOM has shown that Mr. Smith’s expert opinion is based 10 on sufficient facts to meet the standard of FRE 702(b). 11 And fourth, JH Kelly seeks to exclude Mr. Smith’s opinions regarding JH Kelly’s 12 entitlement to payment for the pipe coating work. Mr. Smith generally opines that JH Kelly is not 13 entitled to recover the cost of (1) coating applied in a heat-affected area of the piping system; (2) 14 correcting or repairing defective or damaged coating; or (3) correcting or repairing any factory 15 applied coating that was damaged while in the custody of JH Kelly. See Smith Report ¶¶ 16.3- 16 16.6. He generally concludes that JH Kelly improperly seeks reimbursement because it failed to 17 provide sufficient information to reasonably evaluate its claim. Id. ¶¶ 87-95. 18 JH Kelly argues that Mr. Smith’s testimony is not based on sufficient facts or data and is 19 not the product of reliable principles or methods because he did not personally perform a “cost 20 analysis” of JH Kelly’s change order requests. Dkt. No. 208 at 9. JH Kelly’s argument appears to 21 seize on a disclaimer at the end of Mr. Smith’s report, in which he writes that “a cost analysis of 22 the CORs is being handled by others.” Smith Report ¶ 95. But the Court cannot assess the import 23 of this disclosure because neither Mr. Smith nor JH Kelly have explained what this “cost analysis” 24 would entail and why its absence renders Mr. Smith’s opinions unreliable. The Court accordingly 25 does not conclude that Mr. Smith’s lack of cost analysis renders his opinion speculative or 26 unreliable under Rule 702 or unfairly prejudicial under Rule 403. In sum, JH Kelly’s motion is iii. JH Kelly’s Motion to Exclude Expert Testimony of Anthony Gonzales (Dkt. 1 No. 209) 2 AECOM retained Mr. Gonzales to provide an analysis and quantification of the 3 backcharges it seeks to recover from JH Kelly and to rebut the opinions of Mr. McKinnon and Dr. 4 Ibbs. See Dkt. No. 209-1, Declaration of Eric A. Grasberger ISO Daubert Motion to Exclude 5 Expert Testimony of Anthony Gonzales, Ex. 1 (“Gonzales Report”). JH Kelly raises two 6 categories of arguments to preclude Mr. Gonzales from testifying. As explained below, the Court 7 agrees with the first category but rejects the second. 8 JH Kelly first asks the Court to exclude as “improper legal opinions” Mr. Gonzales’s 9 opinion that JH Kelly is not entitled to recover its: (1) post-project completion damages; (2) 10 change management support fees; and (3) costs for changed work due to untimely and insufficient 11 notice based on the Subcontract provisions, including Sections 12.3.2, 13.1.1 and 13.3.3. Dkt. No. 12 209 at 6-9. 13 After reviewing the Gonzales Report, the Court agrees with JH Kelly that although these 14 opinions are purportedly based on Mr. Gonzales’s reading of the Subcontract, they are at bottom 15 attorney argument dressed up as expert opinion. Mr. Gonzales’s opinion that various provisions 16 of the Subcontract preclude JH Kelly from recovering its costs is just straightforward contract 17 interpretation, and as such it impermissibly treads on ultimate issues of law. See United States 18 Postal Serv. v. Jamke, No. 115-CV-01806-LJO-EPG, 2017 WL 131991, at *5 (E.D. Cal. Jan. 12, 19 2017) (“Generally, contract interpretation is not an appropriate subject for expert testimony, 20 because it requires an expert to make conclusions of law.”) (citing Hangarter v. Provident Life 21 and Acc. Ins. Co., 373 F.3d 998, 1016 (9th Cir. 2004)); see also Aerojet Rocketdyne, Inc. v. Global 22 Aerospace, Inc., No. 2:17-cv-1515 KJM-AC, 2021 WL 1839695, at *3 (E.D. Cal. May 7, 2021) 23 (excluding portions of expert’s proposed testimony that reflected contract interpretation because 24 they were “inadmissible as treading on ultimate issues of law”). Accordingly, Mr. Gonzales may 25 not opine at trial that JH Kelly is not entitled to recover: (1) Post Project Completion Damages; (2) 26 Change Management Support Fees; and (3) costs for changed work due to untimely and 27 insufficient notice based on the Subcontract provisions. 1 Project is based on assumptions unsupported by sufficient facts or data under FRE 702(b) and 2 creates a substantial risk of unfair prejudice under FRE 403. See Dkt. No. 209 at 9-16. Similarly, 3 JH Kelly also contends that Mr. Gonzales relies on unreliable methodology and insufficient facts 4 to opine that JH Kelly is not entitled to compensation for changed work and damages for 5 productivity loss. Id. at 17-21. 6 In the Court’s view, these arguments primarily reflect JH Kelly’s substantive 7 disagreements with Mr. Gonzales. See, e.g., id. at 10 (“To draw his conclusions, Gonzales 8 compared (1) time and material unit rates for change order work (the rates specified in the 9 Subcontract) to (2) bare labor rates used in deriving the bid for the base Subcontract work. This is 10 a comparison of apples to oranges.”) (citations omitted); 14 (“Gonzales’s opinion that Kelly 11 underbid because it paid incentives to workers is not tethered to the underlying facts.”); 16 12 (“Gonzales’s opinion that a variance should call into question Kelly’s bid is not consistent with 13 Gonzales’s own opinions about the insignificance of bid to budget variances.”); 18 (“[B]ecause of 14 Gonzales’s failure to analyze the history of change order requests, Gonzales improperly, and 15 arbitrarily, refused to provide credit to Kelly for certain change order requests.”). The other 16 arguments simply point out alleged flaws in Mr. Gonzales’s analysis. See id. at 20 (“This 17 superficial analysis led to several critical missteps. Gonzales could not verify the cost report that 18 he relied upon to form his opinion.”); id. (“Gonzales’s analysis, however, is not consistent with 19 industry standards and relies upon an insufficient sample of work.”). As the Ninth Circuit has 20 repeatedly instructed, alleged errors in Mr. Gonzales’s analysis should be tested during trial 21 “through competing evidence and incisive cross-examination.” Murray v. S. Route Mar. SA, 870 22 F.3d 915, 925 (9th Cir. 2017) (citations omitted). The Court also finds no risk of unfair prejudice 23 and accordingly will not preclude Mr. Gonzales from testifying on this ground. 24 JH Kelly’s motion is GRANTED as to Mr. Gonzales’s opinion that JH Kelly is not 25 entitled to recover: (1) Post Project Completion Damages; (2) Change Management Support Fees; 26 and (3) costs for changed work due to untimely and insufficient notice pursuant to the Subcontract 27 provisions but is DENIED on all other grounds. iv. JH Kelly’s Motion to Exclude Portions of Expert Testimony and Reports of 1 Ted Scott (Dkt. No. 210) 2 AECOM retained Mr. Scott as an expert witness to quantify the construction delays that 3 impacted the Subcontract work. See Dkt. No. 210-1, Declaration of Eric A. Grasberger in Support 4 of Daubert Motion to Exclude Expert Testimony of Ted Scott, Ex. 1 (“Scott Report”) ¶ 1.5. Mr. 5 Scott’s report is organized into three “Phases”—engineering, construction, and commissioning. 6 Id. ¶ 1.7. Phase 1 (engineering) includes two “Windows”; Phase 2 (construction) includes four 7 “Windows”; and Phase 3 (commissioning) includes eight “Windows.” See id. at 3-14 (executive 8 summary). For each Window, Mr. Scott defines the “critical path” time period at issue and 9 attempts to allocate days of delay to the critical path among PG&E, AECOM and JH Kelly. Id. 10 Mr. Scott’s total allocation of days of delay for the entire project is 425 days of delay to PG&E, 40 11 days of delay to AECOM and its separate third-party subcontractors, and 105 days of delay to JH 12 Kelly. See id. at 14. 13 While JH Kelly intends to challenge the entirety of Mr. Scott’s allocation of 105 days of 14 delay to JH Kelly at trial, its present motion seeks to exclude the following allocations of delay to 15 JH Kelly: (1) 35 days of delay in Phase 1/Window II; (2) 32 days of delay in Phase 2/Window I; 16 (3) 15 days of delay in Phase 2/Window II; (4) 6 days of delay in Phase 2/Window III; and (5) 8 17 days of delay in Phase 2/Window IV. Dkt. No. 210 at 7. 18 JH Kelly generally argues that Mr. Scott’s testimony is based on assumptions unsupported 19 by sufficient facts or data under FRE 702(b) and creates a substantial risk of unfair prejudice under 20 FRE 403. JH Kelly’s challenge to Mr. Scott’s analysis of the delay in Phase 1/Window II is 21 representative of its overall approach. There, Mr. Scott addresses an alleged 70-day delay to the 22 critical path (from February 24, 2017, to May 5, 2017) because of the delayed issuance of certain 23 drawings. Scott Report at 6. Mr. Scott opines that this 70-day delay is the result of two different 24 issues: (1) PG&E’s preferential design changes; and (2) the need to reroute the duct bank around 25 the existing utility conflict. Id. Mr. Scott attributes 100% of the first issue, “PG&E’s preferential 26 design changes,” to PG&E, and 100% of second issue, the “utility conflict,” to JH Kelly. See id. 27 at 6, 55. Mr. Scott then equally splits the 70 days of delay between PG&E and JH Kelly, 1 JH Kelly argues that Mr. Scott’s opinion on this issue should be excluded “because it is 2 based on improper assumptions” and then lists the following assumptions: 3 • Scott assumes that JH Kelly is 100% responsible for the utility conflict—which AECOM 4 (as the engineer or record) designed without any input from Kelly—while AECOM’s own 5 electrical engineering expert does not apportion any percentage of fault (let alone 100% fault) to JH Kelly; 6 • Scott assumes that AECOM worked continuously from February 24, 2017 to May 5, 2017 7 to resolve the utility conflict without any evidence to support this assumption; 8 • Scott assumes that PG&E’s preferential decision to re-route the duct bank around the 9 property is irrelevant while AECOM’s own electrical engineering expert and lead engineer 10 opine and testify that the delay resulting from the utility conflict could have been mitigated or avoided entirely if PG&E had not made that preferential decision; and 11 • Scott assumes that the impact of the PG&E’s preferential design changes and the utility 12 conflict are equal and should be apportioned 50/50 to this time period without any 13 evidence to support this assumption.

14 See Dkt. No. 210 at 9-10. The rest of JH Kelly’s motion follows suit. See id. at 13 (“Scott should 15 not be permitted to make this assumption, as there is no evidence to support this assumption, and 16 he is not qualified to opine on this electrical engineering issue.”); id. at 15 (“As a result of Scott’s 17 incorrect reliance on the project-wide 900 lf figure, Scott drastically overstates Kelly’s planned 18 productivity rate at 225 lf/day for the area only under the Auxiliary Building.”); id. at 17 (“There 19 is no evidence to support Scott’s opinion that the that work on the duct bank was delayed by the 20 Valve Strike event, or that the work on the duct bank was on the critical path for the project at this 21 time.”). 22 The Court agrees with AECOM that JH Kelly’s challenge is an attempt to repackage its 23 anticipated cross-examination of Mr. Scott as a Daubert motion. See Dkt. No. 220. As the Court 24 has explained, the inquiry into the admissibility of expert testimony is “a flexible one” where 25 “shaky but admissible evidence is to be attacked by cross examination, contrary evidence, and 26 attention to the burden of proof, not exclusion.” TechShop, Inc. v. Rasure, No. 18-cv-01044-HSG, 27 2019 U.S. Dist. LEXIS 69800, at *3 (N.D. Cal. April 24, 2019) (citing Primiano, 598 F.3d at 1 564). Here, the Court finds that Mr. Scott’s opinion is sufficiently based on his experience in the 2 || field of schedule analysis, his review of Project documents including schedules issued by both 3 AECOM and JH Kelly, and the testimony of persons with knowledge of the key events on the 4 || Project, to meet the standards of Rule 702. And the Court finds his testimony relevant to JH 5 || Kelly’s claims for costs caused by delays on the Project. JH Kelly’s assertion that Mr. Scott made 6 || “improper” or “unsupported” assumptions and reached faulty or irrelevant conclusions plainly 7 bear on the weight of his testimony, not its admissibility. See United States for Use & Benefit of 8 Bergelectric Corp. v. Sauer, Inc., No. 5:18-CV-00612-EJD, 2020 WL 470273, at *2 (N.D. Cal. 9 || Jan. 29, 2020) (“District courts within and outside this district have often concluded that experts’ 10 || decisions about what data to use in their analysis bear on the weight, not the admissibility, of 11 expert testimony.”) (citations omitted and cleaned up). And as to the risk of unfair prejudice under 12 || Rule 403, the probative value of Mr. Scott’s analysis is not substantially outweighed by the risk of 13 unfair prejudice, undue delay, or any other Rule 403 consideration. To the extent AECOM fears 14 || the jury will assign undue weight to Mr. Scott’s “improper” assumptions, it will have every 15 opportunity to undermine the testimony through effective cross-examination. JH Kelly’s motion a 16 || is accordingly DENIED.
