City, Airport and Project Overview

RFP NO. 202577961 On-Call Architectural & Engineering Services September 17, 2025

I. CITY, AIRPORT AND PROJECT OVERVIEW

The values of equity, diversity, inclusivity, accessibility, and sustainability are inherent to the City’s strategy to develop and maintain prosperous communities. Accordingly, these values are imbedded into all the City’s procurement processes to ensure competitive procurements that offer equitable opportunities for all potential Proposers, including greater contracted and significant participation for historically underutilized businesses to ensure Denver’s long-term economic, social, and environmental health. Through equitable procurements, the City is committed to working to remove barriers and increase access to City contracting opportunities for all historically underutilized and small businesses including those owned by veterans and individuals living with disabilities as well as those in economically distressed or redlined neighborhoods. It is a primary value to promote economic equity by engaging a more inclusive community of Proposers and contractors, both as prime and sub-contractors to address socioeconomic disparities. Through this promotion of equity and inclusion (EDI), the City strives to improve opportunities that ensure fair and just access to jobs, housing, education, mobility options, and healthier communities. It is the City’s expectation that all successful Proposers demonstrate their commitment to these City values through their procurement responses and post contract and/or lease activities.

Each procurement opportunity is to be approached with ethical and honest behavior. The City will solicit, evaluate, and award contracts based upon the Proposer’s alignment with the City’s values as it relates to its approach, proven experience, ability to perform work, costs, and pricing. DEN is looking for Proposers that demonstrate a history of equity, diversity, integrity, stewardship, innovation, and humanity. The City is looking for Proposers that have equity, diversity, and inclusion (EDI) embedded in their policies, procedures, practices, initiatives, and exhibit actionable results and ensures that of those that they partner with.

The City’s values may be demonstrated through but are not limited to: (a) workforce expansion; (b) utilization of and work with the historically underutilized community, separate from required certified goals; (c) environmental sustainability and (d) EDI and Equal Employment Opportunity (EEO) programs for staff.

DEN plays a unique role as a gateway to the world for the region, our passengers, our communities, and our partners. As such, DEN has a generation of operators, concessionaires, designers, builders, planners, and small businesses that are stronger and more successful because of this work. DEN has also helped build new businesses that have flourished and grown into mature industry leaders. As part of its new Vision 100 plan, DEN intends to expand this legacy by looking to the community that has succeeded in the past at DEN to bring the next generation forward.

In its review of this contract opportunity, DEN believes that the scope of work and firms in the industry lends itself to unique partnership opportunities, and therefore, highly encourages firms that have historically proposed as prime contractors to serve as subcontractors to M/WBE firms in their contract with DEN, or to create Joint Ventures with M/WBE firms. A focus of this partnership should be for the contracting partners to build a meaningful relationship that is not merely transactional to meet a numerical goal. The objective is to afford the M/WBE firm the opportunity to learn from the large contractor, grow its financial capacity, build its generational wealth and its portfolio, and increase its capability to perform new commercially useful functions on future contracts.

RFP NO. 202577961 On-Call Architectural & Engineering Services September 17, 2025

Rights of DEN DEN reserves the rights to cancel or modify this RFP at any time and to reject any or all proposals for any reason or for no reason. This RFP is an open and equitable invitation for proposals, and each proposal constitutes an offer to contract that DEN may consider in its sole and absolute discretion. Any errors or omissions in a proposal may result in the rejection and disqualification of the entire proposal. Errors, omissions, and other acts that may result in proposal rejection and disqualification include, but are not limited to, failure to strictly comply with the RFP requirements or any applicable ordinances, rules, or policies; the submission of any inaccurate or false information; any improper communications or collusion involving Proposers; default or termination for cause of any public or private contracts within the past five years; delinquent arrearages owed to DEN; and failure to submit proof of licensing or franchise authority and any related exclusivity requirements.

Notwithstanding the broad rights reserved to DEN to reject and disqualify any or all proposals, DEN may waive any immaterial deficiencies in proposals and may allow Proposers to cure any such deficiencies if an opportunity to cure is determined by DEN to be in DEN’s best interests. If given an opportunity to cure, Proposers will be notified of the allotted time to correct the identified deficiency; failure to correct the deficiency in the time allotted may result in proposals being deemed non-responsive and disqualified.

DEN’s waiver of an immaterial deficiency will in no way modify the RFP or excuse Proposers from full compliance with all RFP specifications. DEN may exercise the foregoing rights at any time without notice and without any liability whatsoever to any Proposer or other party. By responding to this RFP, each Proposer is deemed to accept and agree to all of these terms and conditions and to waive any rights to challenge DEN’s determinations regarding proposal deficiencies in accordance with this section.

During the evaluation process, DEN reserves the right to request additional information from any Proposer, to seek clarification of information provided, to conduct its own due diligence with respect to any Proposer or proposal, including Self-Guided Tours of a Proposer’s other operations, reference checks, credit checks, health department checks, or any other investigations deemed necessary.

Confidentiality of Records Documents submitted pursuant to this RFP will be subject to the Colorado Open Records Act, C.R.S. §§ 24-72-201, et seq. Information clearly marked as confidential and proprietary will be kept confidential by City, unless otherwise provided by law. City will attempt to notify the Proposer if a request is made for pages of documents clearly marked as confidential and proprietary so that the Proposer may take any action it deems necessary to defend the request. The Proposer, not the City, shall be the entity responsible for defending against Colorado Open Records Act disclosures for any records claimed by the Proposer to be confidential and proprietary.

Proposer Agreements Proposers may submit proposed agreements of any form (contracts or documents) that contain supplemental terms and conditions that the Proposer desires to be considered by the City for inclusion in the contract. Such forms may include Proposer’s software licensing agreements, maintenance contracts, and technical support agreements. By accepting delivery of these items, DEN is not bound to accept them as part of an ensuing contract. DEN may negotiate such supplemental terms and conditions that do not materially conflict with the contract terms and conditions detailed in this RFP and do not materially change the nature of this solicitation or adversely affect competition. If the parties cannot agree on the terms of the contract, including any terms desired by Proposer, DEN may terminate negotiations with the Proposer and enter into a contract with another responsive Proposer. Certain of DEN’s contract provisions are required by Federal, State and/or City law and policy and are not subject to modification.

RFP NO. 202577961 On-Call Architectural & Engineering Services September 17, 2025

Minority and Women-Owned Business Enterprise (MWBE) Participation MWBE Responsiveness Requirements

The below-listed DSBO proposal requirements are all conditions of responsiveness. Failure to submit a responsive proposal constitutes cause for rejection thereof.

A. Non-Competition

Proposer shall not restrict an MWBE from providing subconsulting or subcontracting quotations to other Proposers. Any Proposer who does so shall cause their proposal to be rejected. §§ 28-59(f), 28- 63(f), D.R.M.C.

B. Joint Ventures If Proposer is participating in a joint venture with a certified MWBE firm, proposer must submit the firm’s Joint Venture Agreement to DSBO at least 10 working days prior to the RFP-response submission. The Joint Venture must be approved by DSBO.

A Joint Venture is an association of an MWBE firm and one or more other firms to carry out a single, for-profit business enterprise, for which the parties combine their property, capital efforts, skills and knowledge, and in which the MWBE is responsible for a distinct, clearly defined portion of the work of the contract and whose share in the capital contribution, control, management, risks, and profits of the joint venture are commensurate with its ownership interest.

DSBO will count a portion of the total dollar value of the joint venture contract toward the MWBE requirement equal to the distinct, clearly defined portion of the work that the MWBE performs with its own forces in a NAICS code in which the firm is MWBE certified. The joint venture agreement MUST specify the services, dollar value, reporting structure, and details of the MWBE’s performance requirements associated with their percent of the joint venture ownership.

C. Commitment to MWBE Participation Proposer shall include with their proposal a completed DSBO form, entitled “Commitment to MWBE Participation,” stating their committed MWBE participation percent on this project. The committed participation level will be inserted into any resulting contract and the Contractor/Consultant must comply with that committed participation amount during the term of the contract.

D. Good Faith Effort

If Proposer cannot meet the MWBE requirement established by DSBO or is able to only meet part of the requirement, they shall furnish to DSBO, with their proposal, a comprehensive statement of their good faith efforts to meet the requirement, along with supporting documentation demonstrative thereof. This means that Proposer must show that they took all necessary and reasonable steps to achieve the MWBE requirement which, by their scope, intensity, and appropriateness to the objective, could reasonably be expected to obtain sufficient MWBE participation, even if they were not fully successful.

The statement of good faith efforts should address each of the categories outlined in the DSBO Ordinance, §§ 28-60, 28-64, D.R.M.C., and any additional criteria established by rule or regulation. As part of their good faith efforts, Proposers are encouraged to solicit the support and assistance of DSBO by contacting the procuring agency’s Contract Administrator (CA)/Buyer with specific questions; the CA/Buyer will coordinate with DSBO to reply thereto. All good faith efforts information must be complete, accurate, adequately documented, and submitted with the proposal. Good faith efforts

RFP NO. 202577961 On-Call Architectural & Engineering Services September 17, 2025 must be demonstrated to be substantive and not merely for formalistic compliance with the DSBO Ordinance.

To award a contract to a proposer that has failed to meet the MWBE requirement, DSBO will determine whether Proposer made good faith efforts to actively, effectively, and aggressively seek MWBEs to meet the MWBE requirement prior to proposal submission, which determination shall include consideration of Proposer’s MWBE Utilization Plan strategies to meet their MWBE participation commitment. Failure of Proposer to show good faith efforts shall render their proposal ineligible for further consideration with the City.

E. DSBO Program Requirements Handbook (DSBO Handbook) – Signature Statement Proposer must submit the completed and signed Signature Statement of the DSBO Program Requirements Handbook with their proposal documents to be found responsive. The signed Signature Statement evidences proposer’s review and agreement to comply with the requirements outlined in the DSBO Handbook.

F. MWBE Utilization Plan

Proposer shall include with their proposal a completed DSBO form, entitled “MWBE Utilization Plan,” stating their strategy for meeting the MWBE requirements, including certified small business utilization and expectations for their lower tiered MWBE-certified firms. To meet the MWBE Utilization Plan minimum responsiveness requirements, Proposer must meaningfully address each of the form’s sections; any section that is blank or has “N/A” as a response may deem the proposer non-responsive. Contract execution will be conditioned upon a DSBO-approved MWBE Utilization Plan, unless DSBO has determined that Proposer made a 0%-participation good faith effort.

Exception: if Proposer is submitting documentation of a good faith effort that states that they can only meet 0% of the MWBE requirement, they are exempt from this responsiveness requirement and need not submit a completed MWBE Utilization Plan form.

Compliance with those, and any additional requirement contained herein, are conditions of responsiveness. The DSBO Ordinance, its accompanying rules and regulations, and additional MWBE guidance are available here:
