About this file
This file contains drawings and specifications for repairing stair bracing at the Coquille Stair Bracing project located in Portland, Oregon. The drawings show existing cross bracing and recommend installing new longitudinal bracing consisting of 2x8 pressure treated wood braces bolted between 4x6 posts with 5/8-inch diameter stainless steel carriage bolts and washers. One drawing provides details for a new longitudinal stair bracing assembly using 2x8 pressure treated wood braces bolted between 4x6 posts with two 5/8-inch diameter stainless steel bolts and washers. The related federal contract opportunity is solicitation number 140F0321R0007 from the Department of the Interior Fish and Wildlife Service for repair work at the OR-OREGON ISLANDS NWR - SOUTH STAIRS CON project.
