About this file
This file is a comprehensive design drawing set for the Mesa Falls Boardwalk Replacement project located in the Caribou-Targhee National Forest within the Ashton/Island Park Ranger District in Idaho. The project consists of complete replacement of existing boardwalk infrastructure, including removal of pressure-treated stringers and decking with new Parallam wood beam structures and pressure-treated decking throughout.
The scope includes replacement of approximately 11,756 board feet of 3.5"x9.5" Parallam wood beams or equivalent, 2,919 board feet of beam spacers, 27,184 board feet of 3"x6" pressure-treated decking, 741 board feet of 2"x14" stair stringers, and hardware connections utilizing 5/8" galvanized hex head bolts with nuts and malleable washers. The project encompasses multiple sections totaling approximately 6,500 linear feet of boardwalk, including upper boardwalk sections (A-Q, 2,705 square feet), lower boardwalk sections (B-K and overlooks, approximately 3,400 square feet), and numerous stairway sections (1-40, totaling approximately 3,500 square feet). The schedule of items includes mobilization and selective demolition of existing boardwalk as lump sum items, with an optional item for replacement of six 6-foot redwood benches. The design incorporates steel safety railings, viewing platforms at six locations, and connections to existing structural elements with detailed specifications for post anchoring, beam splicing, and slope management (2% maximum). All construction must comply with accessibility standards and include proper drainage considerations throughout the facility.
