The General Services Administration (GSA), Public Buildings Service (PBS), intends to construct a new fully functional Land Port of Entry (LPOE) in Coburn Gore, Maine. The Government will utilize the "Construction Manager as Constructor (CMc)", also known as "Construction Manager at Risk" or "Guaranteed Maximum Price (GMP)", delivery method. The CMc project delivery method includes requirements for Design Phase Services and the Option(s) for Construction Services at a Guaranteed Maximum Price (GMP). The project shall adhere to the GSA Design Excellence and Operational Excellence guidelines, and the GSA PBS Core Building Standards. The proposed expansion and modernization of the LPOE complex located at 6092 Arnold Trail in Coburn Gore, Maine, was designed to strengthen supply chains, improve operational capabilities and facility infrastructure, spur economic growth, and bolster the country's security. This LPOE is designated within the National Register of Historic Places (NRHP) and was originally constructed in 1932. The 3.6-acre U.S. Inspection Station – Coburn Gore, Maine was entered into the National Register of Historic Places (NRHP) on 9/10/14. Important in the history of border security in the United States, the Coburn Gore LPOE is one of several extant examples of a wave of border crossing stations constructed between 1930 – 1943, as further detailed in the related 2014 Multiple Property Listing for U.S. Border Inspection Stations 1930 – 1943. The deficiencies at the LPOE fall into two broad categories: (1) limited capacity and facilities for port operations; and (2) the condition of the existing buildings. Thus, the expansion and modernization of the LPOE would provide a port that is functional, accessible, and equitable for U.S. Customs and Border Protection (CBP) to more efficiently carry out its agency mission and their operations and interactions with the public. Upon completion, the LPOE is anticipated to address these deficiencies and facilitate the efficient functioning of CBP operations while adhering to their POR, 2023 Design Standards, and the 2025 PBS Core Building Standards. Project Goals: The main goals for this project include the following: Maintain full operations and current throughputs for all Port agencies throughout Construction. Maintain accessibility throughout the site during construction implementation. Maintain site security throughout construction. Ensure Continuous availability of utilities (power, phone/data, water, sewer, and stormwater) and emergency power during phased construction. Deliver Design and Construction Excellence that meets CBP's POR, CBP 2023 Design Standards, and PBS's Core Building Standards. Address significant problems and issues with each existing facility and its surrounding parcel. Maintain Coburn Gore's significant historic character. Provide buildings and infrastructure that incorporate durable construction materials and sustainable design elements and are climate resilient. …
