SPECIFICATIONS: Construct the project in compliance with

Federal Highway Administration Standard Specifications for

Construction of Road and Bridges on Federal Highway Projects

(FP-14) and applicable Forest Service Supplemental

Specifications (FSSS).

DEWATERING & EROSION CONTROL PLAN: Submit a

Dewatering and Soil Erosion and Sediment Control Plan to the

Contracting Officer for approval at least seven (7) days prior to beginning work. See Section 157 of the Supplemental

Specifications for details. Construct temporary means to divert the flow of the live stream as necessary to perform work. Do not pump water from excavations directly into the live stream.

STREAM CROSSINGS: The Contractor is allowed to cross the live stream during construction.

CONCRETE: Use Class A(AE) Concrete for Precast members.

The required 28-day compressive strength (F'c) is 5,000 psi with an entrained air content of 5% ± 1%. Finish all precast elements with an ordinary surface finish. Make all concrete in accordance with an approved mix design. Chamfer all exposed edges of concrete 3/4" and fillet all acute angles 3" unless otherwise noted.

REINFORCING STEEL: Use reinforcing steel of the deformed type conforming to AASHTO M31 (ASTM A615) Grade 60.

Concrete cover is as shown; where not shown it must conform to AASHTO. Cut and bend reinforcing steel in conformance with ACI 315. Lap splice bars 2' min.

HARDWARE AND STRUCTURAL STEEL: Use shapes, plates and bars meeting the requirements of ASTM A36, unless otherwise specified in these plans. Use hardware meeting the requirements of ASTM A325, except as noted in the drawings.

SUPERSTRUCTURE: The information provided on this sheet and in the notes are intended to show the general configuration, materials, and loading requirements for the bridge superstructure. The superstructure must incorporate the elements shown in the TYPICAL SECTION on this sheet, and conform to the dimensions shown.

Fabricate all top and bottom chords, verticals, and diagonals, from square or rectangular weathering steel tubing.

Detailed shop drawings and design calculations for the final bridge design must be submitted for review a minimum of 6 weeks prior to fabrication. Refer to The Forest Service Supplemental Specifications, Section 555, for additional requirements.

DESIGN: The design of all prefabricated bridge superstructure elements shall comply with the AASHTO "LRFD Guide

Specifications for Design of Pedestrian Bridges", 2009, and AASHTO LRFD Bridge Design Specifications, 8th edition, with current interims. The final design shall be prepared by a licensed professional engineer whose signed seal shall be on the design documents.

Design notes as follows:

90 psf Pedestrian Live Load

20,000 lbs. Vehicular Live Load (H10)

165 psf Ground Snow Load

All other loads, combination of loads, deflection criteria, etc. shall be as specified in the Guide Specifications for

Design of Pedestrian Bridges. Provide camber for 100% of the full dead load deflection plus 1% of the full length of the bridge.

STEEL FABRICATION: The steel bridge truss shall be fabricated by a plant with AISC-Intermediate Bridge

Certification.

MATERIALS: Steel: Use steel shapes, plates and bars of weathering steel conforming to ASTM A588 or ASTM A242.

Use hollow steel shapes of weathering steel conforming to ASTM A847 or ASTM A606 (Fy= 50,000 psi). Minimum steel thicknesses shall be as specified in the Guide Specifications for Design of Pedestrian Bridges. Use high strength bolts conforming to AASHTO M164, Type 3, unless noted otherwise.

All welding shall conform to the Bridge Welding Code, AWS D1.5.

Timber Decking: Furnish decking of untreated, responsibly-sourced, Ipe (Tabebuia Spp Lapacho Group). Design properties are to be in accordance with U.S. Forest Products Laboratory publication; "Tropical Timbers of the World".

2. Install Geocell in accordance with Forest Service Supplemental

Specifications (FSSS) 272.06, holding lines and grades in place with suitable side forms (i.e. "stretcher frames" or steel stakes) to ensure cells are expanded to the minimum dimension required by the manufacturer.

3. Backfill Geocell with coarse granular backfill per FSSS Subsection

703.03(c).

4. Place Class 1, Type A Separation Geotextile under Geocell and wrap over top after backfilling (incidental to Item 27201).
