About this file
This document is an exhibit detailing the existing roof structure and proposed structural alterations for the Houlton Land Port of Entry Facilities Repair and Alterations project. The exhibit shows the existing roof framing plan and indicates that the project will involve reviewing the existing beams to support the weight of a new stair and proposed rooftop mechanical equipment. It also shows that a new mechanical screen will be installed on the roof, requiring an assessment of the existing structure's capacity to support it. The document is part of a larger federal contract opportunity solicitation for Construction Manager as Constructor (CMc) / Construction Manager as Risk (CMAR) services for this project, which has an estimated construction value between $22-32 million. The solicitation sets forth requirements for technical and price proposals, with a proposal due date of November 11, 2024.
