Re: Engagement of Linden Analytics Group, LLC as Expert Procurement Consultant Matter: Metropolitan Transit Development Corp. v. Illinois Department of Transportation Protest No. IDOT-BPC-2022-0047 RFP No. IDOT-TS-2022-014 — Illinois Integrated Transit Modernization Program (IITMP) Calderwood & Harkness Matter No. 1031-00003

Dear Dr. Fernwood:

1. Introduction and Purpose of Engagement

Calderwood & Harkness LLP represents Metropolitan Transit Development Corp. ("MTDC"), a unit of local government and public transit authority organized under the Illinois Local Mass Transit District Act, 70 ILCS 3610, headquartered at 550 West Adams Street, 14th Floor, Chicago, Illinois 60661. MTDC operates one of the largest public transit networks in the State of Illinois and is a major recipient of both state and federal transportation funding.

MTDC has filed an agency-level bid protest, designated as Protest No. IDOT-BPC-2022-0047, with the Office of Chief Counsel of the Illinois Department of Transportation ("IDOT"). The protest challenges the award of the Illinois Integrated Transit Modernization Program ("IITMP") contract, solicited under RFP No. IDOT-TS-2022-014, to Pinnacle Transit Solutions, Inc. ("Pinnacle"). The protest was filed on August 8, 2022, pursuant to the Illinois Procurement Code, 30 ILCS 500/20-80, and the implementing regulations set forth at 44 Ill. Admin. Code § 1.5530. The protest raises significant questions regarding the reasonableness of IDOT's source selection decision, the adequacy of its cost-realism analysis, and the potential application of unstated evaluation criteria — questions that, in our assessment, require the analytical support of a qualified procurement expert.

The purpose of this letter is to retain Linden Analytics Group, LLC ("Linden") and you, Dr. Alicia Fernwood, as an expert procurement consultant to assist MTDC in the protest proceeding and any potential litigation escalation that may follow. Calderwood & Harkness has identified Linden's expertise as an independent procurement analytics and cost-estimation consultancy as uniquely suited to this engagement. In particular, your background as a former federal contracting officer with over twenty years of experience in competitive source selections, cost-realism analyses, and best-value tradeoff determinations is specifically relevant to the issues raised in this matter. We are confident that your independent analysis will materially strengthen MTDC's position in the protest proceeding and, if necessary, in any subsequent judicial action.

This letter sets forth the terms and conditions under which Linden and Dr. Fernwood will provide expert consulting services to Calderwood & Harkness on behalf of MTDC. Upon your countersignature below, this letter shall constitute a binding agreement between Calderwood & Harkness LLP and Linden Analytics Group, LLC.

2. Background of the Dispute

To provide context for the scope of services described in this engagement letter, the following summarizes the relevant facts and circumstances of the procurement at issue.

On January 18, 2022, IDOT issued RFP No. IDOT-TS-2022-014 for the Illinois Integrated Transit Modernization Program (IITMP), a comprehensive program intended to modernize and integrate transit infrastructure, signaling systems, fleet management technology, and passenger information platforms across multiple transit authorities within the State of Illinois. Proposals were due on April 29, 2022. The contract type specified in the RFP was Firm-Fixed-Price with Cost-Reimbursable Line Items for Technology Development, reflecting the dual nature of the program's established infrastructure components and its more speculative technology development work.

The base performance period under the RFP is seven years, with an anticipated start date of October 1, 2022, and an anticipated end date of September 30, 2029. The RFP also contemplated two three-year option periods, extending the potential contract performance through September 30, 2035. The total maximum contract value, inclusive of the base period and both option periods, is up to $310 million.

MTDC submitted a comprehensive proposal valued at $234.9 million for the seven-year base period. Pinnacle submitted a proposal valued at $247.6 million for the same base period — a price differential of $12.7 million, meaning Pinnacle's proposed price was approximately 5.4% higher than MTDC's proposed price. This price differential is significant in the context of the evaluation and is a central element of MTDC's protest.

The evaluation criteria were set forth in RFP Section M and consisted of four factors, weighted as follows:

According to the Source Selection Decision Document dated July 14, 2022, the Technical Evaluation Panel ("TEP") scored the proposals as follows:

As is evident from the scoring, MTDC held a 30-point aggregate scoring advantage over Pinnacle — an advantage spanning three of the four evaluation factors, including the most heavily weighted factor (Technical Approach) and the Cost/Price factor. Pinnacle outscored MTDC only on Factor 2 (Management & Staffing Plan), and by a margin of only 17 points. MTDC's proposal was both lower-priced and higher-scored in the aggregate.

Notwithstanding MTDC's clear scoring advantage, the Source Selection Authority ("SSA"), Angela Moreau, Deputy Secretary for Multimodal Transportation, selected Pinnacle under a best-value tradeoff rationale. In the Source Selection Decision Document, the SSA cited Pinnacle's "superior workforce integration methodology" and a subcontractor teaming arrangement between Pinnacle and Northlake Signal Systems, Inc. as providing a qualitative advantage that justified the selection of the higher-priced, lower-scored offeror. The Contracting Officer for the procurement is Gerald Fassett, P.E., Chief of the Bureau of Transit Operations at IDOT.

The IITMP contract is funded from multiple sources: Federal Transit Administration ("FTA") Capital Investment Grant funds in the amount of $148.5 million (approximately 60% of the base contract value); State of Illinois General Revenue Fund appropriations in the amount of $74.3 million (approximately 30%); and the IDOT Transit Modernization Fund in the amount of $24.8 million (approximately 10%). The involvement of federal funds may have additional implications for the applicable procurement standards and the availability of additional protest forums, which we may discuss with you as the engagement progresses.

MTDC's protest raises several grounds for challenge, including but not limited to: (a) the unreasonableness of the SSA's best-value tradeoff determination in light of the 30-point scoring differential and the $12.7 million price differential; (b) the inadequacy of IDOT's cost-realism analysis as applied to Pinnacle's cost-reimbursable line items; and (c) the SSA's potential reliance on an unstated evaluation criterion not identified as a sub-factor in RFP Section M. These issues form the core of the analytical work we expect Linden to perform, as described more fully in Section 3 below.

3. Scope of Services

3.1 Protest-Phase Services (Primary Scope)

Linden shall provide the following services during the agency-level protest phase, in support of MTDC's bid protest before the IDOT Administrative Review Board (presided over by Administrative Law Judge Terrence Odum):

(a) Evaluation Scoring Methodology Analysis. Linden shall conduct a detailed evaluation and analysis of IDOT's technical scoring methodology as applied to both the MTDC and Pinnacle proposals under the four evaluation factors set forth in RFP Section M. This analysis shall assess the consistency and reasonableness of the TEP's scoring across each factor and sub-factor, identify any scoring anomalies or inconsistencies, and evaluate whether the TEP's scoring rationale was adequately supported by the record. Linden shall compare the evaluation documentation against the stated criteria in the RFP to determine whether the TEP applied the criteria as written or deviated from the published evaluation scheme.

(b) Best-Value Tradeoff Analysis. Linden shall assess whether the SSA's best-value tradeoff rationale was reasonable given MTDC's 30-point scoring advantage and the $12.7 million price differential. This assessment shall examine whether the SSA's tradeoff analysis adequately explained why Pinnacle's perceived qualitative advantages were worth the additional cost to the government and the departure from the consensus scores of the TEP. Linden shall apply established principles of best-value procurement, drawing upon applicable Illinois procurement law, federal procurement analogies where instructive, and generally accepted procurement practices.

(c) Cost-Realism Analysis Assessment. Linden shall conduct a detailed evaluation of IDOT's cost-realism analysis (or lack thereof) as applied to Pinnacle's cost-reimbursable line items. Specifically, Pinnacle's cost-reimbursable line items totaled $38.4 million, compared to the Independent Government Cost Estimate ("IGCE") of $49.2 million — a shortfall of $10.8 million, representing a 21.95% variance below the IGCE. Linden shall assess whether IDOT adequately evaluated the risk of cost growth, performance shortfalls, or buy-in pricing associated with Pinnacle's substantially below-IGCE cost-reimbursable pricing. Linden shall further assess whether the absence or inadequacy of a cost-realism analysis constituted a material error in the evaluation process that prejudiced MTDC.

(d) Source Selection Decision Document Review. Linden shall review and analyze the Source Selection Decision Document dated July 14, 2022, and assess the adequacy of the documented rationale for selecting the higher-priced, lower-scored offeror. This review shall evaluate whether the rationale articulated by the SSA was sufficiently detailed, internally consistent, and supported by the underlying evaluation record.

(e) Unstated Evaluation Criterion Analysis. Linden shall analyze whether the SSA's reliance on "workforce integration methodology" as a basis for the tradeoff decision constituted the use of an unstated evaluation criterion not identified as a sub-factor or discriminator in RFP Section M. Linden shall review the RFP's stated evaluation criteria, sub-factors, and any amplifying instructions to determine whether "workforce integration methodology" was encompassed within the published evaluation framework or, alternatively, whether its use introduced an impermissible evaluation consideration that was not disclosed to offerors.

(f) Expert Report Preparation. Linden shall prepare expert report materials, including written analyses, declarations, and summary exhibits suitable for submission to the IDOT Administrative Review Board in connection with Protest No. IDOT-BPC-2022-0047. All expert report materials shall be prepared in a format and at a level of detail consistent with the evidentiary standards applicable to administrative protest proceedings before IDOT. Dr. Fernwood shall be prepared to sign declarations and certifications attesting to the accuracy and basis of her expert opinions.

(g) Damages Analysis. Linden shall calculate and analyze MTDC's estimated lost profits over the seven-year base period, applying the appropriate profit margin to MTDC's $234.9 million proposal value, and shall separately quantify MTDC's proposal development costs, which are estimated at approximately $3.2 million. This damages analysis shall be conducted in a manner consistent with established methodologies for calculating bid protest damages under Illinois law and shall be supported by documentation and data provided by MTDC.

(h) Agency Report Review. Linden shall review the Agency Report and Protest File (anticipated to be approximately 2,400 pages) to be produced by IDOT, with a production date currently anticipated as September 30, 2022. Linden shall prepare responsive analytical materials identifying any deficiencies, inconsistencies, or additional issues revealed by the Agency Report and Protest File. This review shall be conducted within a timeframe consistent with the deadlines established by ALJ Odum for the protest proceeding.

(i) Attorney Consultation. Linden shall be available for consultation with Calderwood & Harkness attorneys — specifically, Ian Blackwood (Partner), Sara Hendricks (Senior Associate), and Christopher Aiken (Associate) — in preparation of protest filings, oral argument, and overall protest strategy. This consultation may take place by telephone, videoconference, or in person at Calderwood & Harkness's Chicago offices or such other locations as the parties may agree.

3.2 Litigation-Phase Services (Contingent Scope)

In the event that the agency-level protest is denied by the IDOT Administrative Review Board or the Board fails to issue a timely decision within the time periods prescribed by applicable regulations, and if MTDC elects to escalate the matter to the Illinois Court of Claims under the Illinois Court of Claims Act, 705 ILCS 505, Linden shall provide litigation-phase support services as described below. The litigation-phase scope is contingent in nature and will be activated only if escalation to judicial proceedings becomes necessary.

Litigation-phase services shall include the following:

(a) Formal Expert Report. Preparation of a formal expert report suitable for submission in judicial proceedings before the Illinois Court of Claims, compliant with all applicable rules of evidence and procedure, including any requirements regarding the form, content, and timing of expert disclosures.

(b) Deposition Testimony Preparation. Preparation for and, if called upon, participation in deposition testimony by Dr. Fernwood, including preparation sessions with Calderwood & Harkness attorneys and review of relevant documents in advance of deposition.

(c) Trial Testimony Preparation and Testimony. Preparation for trial testimony and, if called upon, live testimony by Dr. Fernwood at evidentiary hearings or trial proceedings before the Illinois Court of Claims. Dr. Fernwood shall make herself available for trial testimony on dates to be coordinated with Calderwood & Harkness and the Court's schedule.

(d) Supplemental Analysis. Supplemental analysis as may be necessary based on additional discovery materials obtained during the litigation phase, including but not limited to deposition transcripts, interrogatory responses, and documents produced by IDOT, Pinnacle, or other parties or non-parties.

Activation of litigation-phase services requires written authorization from Calderwood & Harkness LLP, and such services are subject to the fee provisions set forth in Section 4.2 below. Unless and until such written authorization is provided, Linden shall have no obligation to perform, and Calderwood & Harkness shall have no obligation to pay for, litigation-phase services.

4. Fees and Payment Terms

Either party may terminate this engagement upon thirty (30) days' prior written notice to the other party; provided, however, that Linden shall complete any work in progress at the time of the termination notice, and shall deliver all work product completed or in progress to Calderwood & Harkness as of the effective date of termination. Linden shall be entitled to payment for all services rendered and expenses incurred through the effective date of termination, prorated as appropriate in the case of the flat fee based on the proportion of work completed at the time of termination.
