About this file
This document is an engineering drawing providing the specifications for the bridge wearing surface replacement on Mitkof Island in the Tongass National Forest, Petersburg Ranger District. The drawing details the requirements for the installation of new running planks, including the plank materials, spacing, fasteners, and connections. It also includes general notes on preparing the bridge deck, treating the wood, and disposing of waste materials.
The related federal contract opportunity is a request for quotation (RFQ) to establish a firm fixed price service contract for the bridge resurfacing work on Mitkof Island. The Period of Performance is from the Date of Award until 31 August 2025. This is a Total Small Business Set-Aside procurement, with the work to be performed on Mitkof Island in Southeast Alaska. The RFQ incorporates a Performance Work Statement (Attachment 1) and a Schedule of Items and Price Sheet (Attachment 4) that provide further details on the required services.
