Raul Hector Castro Douglas AZ Land Port of Entry Design-Build 47PK0125R0002

Sources Sought Amendment 001 (6-24-2025) The GSA is re-opening Sources Sought No. 47PK0125R0002. Previously interested parties, as well as any newly interested parties may respond to this request for information. Definition: A Project Labor Agreement (PLA) is defined as a pre?hire collective bargaining agreement with one or more labor organizations that establishes the terms and conditions of employment for a specific construction project and is an agreement as defined in Subpart 22.5 of the Federal Acquisition Regulation. Pursuant to the FAR, agencies are required to use PLAs in large-scale construction projects unless an exception applies. All PLAs must include: Provisions that bind all contractors and subcontractors on the construction project to the agreement; Allow all contractors and subcontractors on the construction project to compete for contracts and subcontracts without regard to whether they are otherwise parties to collective bargaining agreements; Contain language that guarantees against strikes, lockouts, and similar job disruptions; Set forth effective, prompt, and mutually binding procedures for resolving labor disputes arising during the term of the project labor agreement (i.e. grievance/arbitration procedures), Provide other mechanisms for labor-management cooperation on matters of mutual interest and concern, including productivity, quality of work, safety, and health; Specify the wages and fringe benefits of all classification or crafts working on the project; and Fully conform to all statutes, regulations, Executive Orders, and Presidential Memoranda. One or more labor organizations involved in the construction work. The intent of the use of PLAs is to advance the Government s interests in achieving economy and efficiency in Federal procurement including, by promoting quality assurance, efficient and on-time completion, and stability. In consideration of the above information and any other factors which may be deemed appropriate, the construction community is invited to comment on the use of PLAs for land port of entry general construction projects. The Government intends to use the responses to the Sources Sought for one year as a determination on whether to incorporate a PLA for land port of entry general construction projects in the state of Arizona. This Amended Source Sought is for planning purposes only and shall not be construed as a Request for Proposals or as an obligation on the part of the Government. The Government does not intend to award a contract on the basis of the Amended Sources Sought or otherwise pay for the requested information nor will the Government provide a debriefing. All information will be held in strict confidence and will only be used for the intended purpose. In addition to the original capabilities package requested,* please answer the following questions: 1. Would your firm still be interested in submitting a capabilities statement for consideration if a Project Labor Agreement (PLA) was required on this project? 2. If you answer no, why not? 3. If you answered yes to the previous question, based on your knowledge of the Douglas AZ labor market, for large-scale construction projects, would you expect there to be an impact on your price proposal for this project if a PLA was required by the government? Please explain. Please provide a response by email to daniel.ramirez@gsa.gov. Responses are due no later than 3:00 PM Pacific Time on 7/01/2025. *A firm that previously provided a capabilities package is already in consideration and is not required to submit a whole new capability package. At this time, only responses to the additional questions are requested. However, a firm may choose to make changes to their previous package, or to withdraw it altogether. Newly interested parties not having provided a capability package by the original 5/01/2025 deadline should submit a full capability package, including responses to the new questions above for consideration. Original Posting from 4/17/2025 is Below: Raul Hector Castro Douglas AZ Land Port of Entry Design-Build General Information Document Type: Sources Sought Notice Solicitation Number: 47PK0125R0002 Posted Date: 4/17/2025 Response Date: 5/01/2025 Classification Code: Y1AZ CONSTRUCTION OF OTHER ADMINISTRATIVE FACILITIES AND SERVICE BUILDINGS NAICS Code: 236220 -- Commercial and Institutional Building Construction Small Business Size Standard - $45M Contracting Office Address General Services Administration (GSA), Public Buildings Service (PBS), Acquisition Management Division, 50 United Nations Plaza, 3rd Flr. San Francisco, CA 94102-3434. Description The General Services Administration (GSA) is seeking sources with current relevant qualifications, experience, personnel, and capability to perform as the Design-Build (DB) Contractor for the construction of the Raul Hector Castro (RHC) Land Port of Entry (LPOE), located at 15 Pan American Ave, Douglas, AZ 85607. The existing RHC LPOE in Douglas, Arizona, is a full-service, multi-modal port that inspects Privately Owned Vehicles (POV), pedestrians (PED), and commercially owned vehicles (COV). The southeastern Arizona border town of Douglas is located across the Mexican border from Ciudad Agua Prieta, Sonora. The LPOE at Douglas has been operating since 1914. The current facilities at the RHC LPOE no longer function adequately given the site constraints, steady increase in traffic, and outdated facilities and technologies. The interaction between COV, POV, and pedestrian traffic is a significant concern at the existing LPOE as inadequate pathways and separations between traffic types causes safety and security issues for Customs and Border Protection (CBP) officers and the public. As downtown Douglas is located directly north of the LPOE, congestion in outbound traffic directly impacts flows through the city. With support from the Cities of Douglas and Agua Prieta, the final decision was made to build a new Standalone Commercial Port west of Douglas and to expand and modernize the existing RHC LPOE as a non-commercial facility. Line and Space has been contracted by the U.S. General Services Administration (GSA) to develop a Master Plan and Bridging Documents for the Expansion & Modernization of the RHC Non- Commercial LPOE based on the November 2019 Feasibility Study, and updated requested scope adjustments/changes from CBP. The 2019 Feasibility Study Master Plan assumed that the new Douglas Standalone Commercial LPOE would be completed before construction could begin on the RHC Non-Commercial Port. Since funding for the RHC Port Expansion and Modernization project has become available, this project explores options for the construction/modernization of the RHC Non-Commercial facilities simultaneously with the construction of the New Standalone Commercial Port. The Final Environmental Impact Statement (EIS) required by the EPA s National Environmental Protection Act (NEPA) was issued on 04/24/24 and due to additional requirement for additional land for drainage and storm water retention, a Supplemental Environmental Impact Statement (SEIS) is currently in progress. The project includes the demolition and modernization of the existing facilities, the expansion of the Port to the west and north of the existing site, while maintaining continuous operation of commercial and non- commercial inspection activities during construction. Through the master planning process, substantial consideration was given to re-purposing of the existing Historic Main Building and Historic Garage, however, the decision was made that this option would greatly impede the CBP mission and operations at the Port, therefore the historic structures will be demolished for the new construction. GSA is currently engaged in the Section 106 process with the Arizona State Historic Preservation Office (SHPO) and the consulting parties to complete all final agreements and mitigation measures required. The Preliminary Concept Design documents are scheduled to be completed by June 2025. Per GSAM 536.204 Disclosure of the magnitude of construction projects, the estimated design and construction cost is estimated to be between $200M - $300M. GSA plans to issue a Best Value Request for Proposal (RFP) which will utilize source selection procedures in accordance with FAR Part 15. The selection procedure will employ tradeoffs where technical/management factors are significantly more important than price and price related factors. Following the issuance and evaluation of the RFP, GSA intends to award a Firm Fixed Price (FFP) contract consisting of Design-Build Phase Services. The current GSA project schedule assumes a design-build phase award of January 2026. The project construction duration is approximately 46 months. BY THIS POSTING, GSA WOULD LIKE TO BEGIN EARLY EXCHANGES WITH INDUSTRY. All interested parties should submit a capabilities package to include business classification (i.e. 8(a), Joint Venture, SDVOSB, HUBZone, etc.), as well as examples two (2) to three (3) Design-Build projects completed within the last ten (10) years that included similar scope of work as specified under this project, including large commercial projects of 100,000 GSF or larger; where project scope included: demolition of existing facilities and temporary space to maintain operations during construction phases, with design and construction costs between $200M - $300M. Responses should be kept to a maximum of 10 digital pages total. Please include information on bonding capacity - per contract, and aggregate, as well as proof of active SBA Certification (if applicable) and SAM Registration. This posting serves only as an invitation to express interest for those in the construction marketplace who are capable of performing the anticipated work. Please note that the Government will not compensate any respondents for information provided during these exchanges. Interested parties shall not contact the Architect or their associated Consultants without specific authorization by the contracting officer.
