GENERAL NOTES

A. STRUCTURE EX = 390 YARDSOF HAUL

DESIGN: This structure is designed for HL-93 live loading in accordance with AASHTO LRFD Bridge Design Specifications, 8th Edition.

HYDROLOGY AND HYDRAULICS: This structure has been designed to pass a Q100 flood event with more than 5' of freeboard from upstream side of bridge. Flow data is provided on Sheet 5.

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.

ROAD WORK: Depths of all materials are given as final compacted depths. Remove all berms, existing or created, unless designated to remain, to allow drainage of water from the traveled way.

DEWATERING & EROSION CONTROL PLAN: Submit a dewatering and soil erosion and sediment control plan to the contracting officer for approval at least fifteen (15) days prior to beginning work.

See Section 157 of the Supplemental Specifications, the notes on Sheet 6, and the general requirements shown on Sheet 11. 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.

DISPOSAL: All materials designated for removal become the property of the contractor and are to be disposed of by removing from the forest in an environmentally safe manner in accordance with all local, state and federal requirements. Dispose of excess or unsuitable material at the location designated in FSSS Section 105. Hauling of excess or unsuitable material is incidental to associated work.

TEMPORARY TRAFFIC CONTROL: Submit a temporary traffic control plan to the Contracting Officer for approval at least 30 days prior to intended use.

IN-STREAM WORK: All in-stream work will be done between June 25th and August 1st. Allowance shall be given to the Forest Service to capture and remove fish and other aquatic organisms from within the construction work area prior to and during work activities.

EQUIPMENT STORAGE: Storage of all equipment on government lands will be at a location approved by the CO.

SEEDING: Seed and mulch all disturbed soil that is not within travel way or stream channel. Use Tongass Seed Mix. See FSSS Section 625.

STRUCTURAL STEEL: THE STEEL FABRICATOR MUST BE CERTIFIED BY AISC (AMERICAN

INSTITUTE FOR STEEL CONSTRUCTION) IN THE INTERMEDIATE BRIDGES CATEGORY.

USE STRUCTURAL STEEL MADE OF NEW MATERIAL. PROVIDE CERTIFIED COPIES OF

MILL TEST REPORTS FOR ALL STRUCTURAL STEEL AND BOLTS.

USE STRUCTURAL STEEL SHAPES AND PLATES CONFORMING TO THE REQUIREMENTS

OF AASHTO M270, GRADE 50 (ASTM A709, GRADE 50).

HOT DIP GALVANIZE (SINGLE DIP) ALL STRUCTURAL STEEL MEMBERS IN ACCORDANCE

WITH AASHTO M111 (ASTM A123).

MAIN LOAD CARRYING MEMBERS SUBJECTED TO TENSILE STRESS REQUIRE CHARPY

V-NOTCH TESTING IN ACCORDANCE WITH ASTM A709 SUPPLEMENTAL REQUIREMENTS,

S83 FOR TEMPERATURE ZONE 1. MEMBER COMPONENTS INCLUDE: BRIDGE BEAMS.

FASTENERS: USE HIGH-STRENGTH BOLTS FOR ALL STRUCTURAL FIELD CONNECTIONS.

HIGH-STRENGTH BOLTS, HEAVY HEX NUTS AND HARDENED WASHERS MUST CONFORM

TO THE FOLLOWING REQUIREMENTS, UNLESS APPROVED IN WRITING BY THE

ENGINEER:

· BOLTS ASTM F3125, GRADE A325, TYPE 1

· NUTS APPROPRIATE CLASS OF ASTM A 563

· WASHERS ASTM F 436, TYPE 1

GALVANIZE FASTENERS IN ACCORDANCE WITH AASHTO M232 (ASTM A153).

WELDING: WELD IN ACCORDANCE WITH THE BRIDGE WELDING CODE, AWS D1.5. A

CERTIFIED WELDER IS REQUIRED.

STEEL NOTES

SOLID SAWN MEMBERS: FURNISH SOLID SAWN DECK PLANKS OF COASTAL REGION

DOUGLAS-FIR-LARCH, FULL SAWN, NO. 1 OR BETTER GRADE. FURNISH RUNNING PLANKS OF

COASTAL REGION DOUGLAS FIR-LARCH, ROUGH SAWN, NO. 2 OR BETTER GRADE, AS

SPECIFIED IN THE WWPA OR WCLIB GRADING RULES.

TREATMENT: TREAT SOLID SAWN DECK PLANKS IN CONFORMANCE WITH AWPA UC3B

(ABOVE GROUND, EXPOSED) USING COPPER NAPHTHENATE. TREAT ALL TIMBER IN STRICT

CONFORMANCE WITH THE CURRENT EDITION OF WWPI'S “BEST MANAGEMENT PRACTICES

FOR THE USE OF TREATED WOOD IN AQUATIC ENVIRONMENTS”.

FIELD TREATMENT: FIELD TREAT ALL ABRASIONS AND APPROVED FIELD CUTS WITH WITH

THREE BRUSH COATS OF COPPER NAPHTHENATE (2% SOLUTION). POUR THE FIELD

TREATMENT INTO ANY FIELD-DRILLED HOLES OR NAIL HOLES PRIOR TO INSERTING THE

FASTENERS.
