GENERAL NOTES:

SPECIFICATIONS: MATERIALS AND CONSTRUCTION OF THIS STRUCTURE SHALL BE IN ACCORDANCE

WITH THE STANDARD SPECIFICATION FOR CONSTRUCTION OF ROADS AND BRIDGES ON FEDERAL

HIGHWAY PROJECTS (FP-14) AND STANDARD SPECIFICATIONS FOR CONSTRUCTION OF TRAILS AND

TRAIL BRIDGES ON FOREST SERVICE PROJECTS

DESIGN: THE SUPERSTUCTURE AND SUBSTRUCTURE DESIGN SHALL BE PERFORMED BY THE

CONTRACTOR TO THE GEOMETRY SHOWN ON THESE DRAWINGS AND SHALL BE IN ACCORDANCE WITH

THE CURRENT EDITION OF THE AASHTO LRFD GUIDE SPECIFICATION FOR DESIGN OF PEDESTRIAN

BRIDGES, CURRENT EDITION OF THE AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS, AND THE DESIGN

LOADS SHOWN ON THESE DRAWINGS. PREFABRICATED STEEL SUPERSTRUCTURE DESIGN SHALL BE A

TRUSS CONFIGURATION SIMILAR TO CONTECH CONTINENTAL CONNECTOR PEDESTRIAN TRUSS

UNDERHUNG BRIDGE THAT SHOWN ON THESE DRAWINGS. BRIDGE DESIGN SHALL PROVIDE CAMBER

FOR 100% OF THE FULL DEAD LOAD DEFLECTION PLUS 1% OF BRIDGE SPAN. DESIGN CALCULATIONS

AND SHOP DRAWINGS SHALL BE STAMPED BY A LICENSED PROFESSIONAL ENGINEER. THE

COMPLETED SHOP DRAWINGS AND CALCULATIONS SHALL BE SUBMITTED TO THE CONTRACTING

OFFICER FOR REVIEW AND APPROVAL PRIOR TO FABRICATION.

MATERIALS: USE STEEL SHAPES, PLATES AND BARS OF WEATHERING STEEL CONFORMING TO AASHTO

M270, GRADE 50W (ASTM A588 OR ASTM A242) OR ASTM A847 FOR SQUARE AND RECTANGULAR

TUBING. MINIMUM STEEL THICKNESS SHALL BE AS SPECIFIED IN THE GUIDE SPECIFICATIONS FOR

DESIGN OF PEDESTRIAN BRIDGES. USE HIGH STRENGTH BOLTS CONFORMING TO AASHTO M164, (ASTM

A325), TYP 3, UNLESS NOTED OTHERWISE. USE MALLEABLE IRON WASHERS AGAINST WOOD.

STEEL FABRICATION: THE PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE SHALL BE FABRICATED

BY AN AISC CERTIFIED PLANT - SIMPLE STEEL BRIDGES OR COMPLEX STEEL STRUCTURES. WHEN

STRUCTURAL STEEL IS TO BE WELDED, THE WELDING PROCEDURE SHALL BE IN ACCORDANCE WITH

AWS D1.5 AND SHALL BE SUITABLE FOR THE GRADE OF STEEL AND INTENDED USE OR SERVICE.

ERECTION/REMOVAL PLAN: THE CONTRACTOR SHALL SUBMIT AN ERECTION PLAN FOR THE

PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE AND A REMOVAL PLAN OF THE EXISTING

TIMBER/STEEL BRIDGE TO THE C.O. FOR APPROVAL 30 DAYS BEFORE ERECTION IS SCHEDULED.

DIMENSIONS

1. ALL LONGITUDINAL DIMENSIONS FOR THE STRUCTURE ARE MEASURED HORIZONTALLY AND

INCLUDE NO CORRECTION FOR GRADE.

DEWATERING AND SOIL EROSION CONTROL

1. PROTECT AGAINST SOIL EROSION AND SEDIMENTATION DURING CONSTRUCTION IN ACCORDANCE

WITH FP-14, SECTION 157 AND THE PROJECT PERMITS.

2. CONTRACTOR AND LABORERS SHOULD ANTICIPATE WATER INFILTRATING THE EXCAVATIONS.

3. ALL WORK SHALL BE COMPLETED PER THE CONTRACT SPECIFICATIONS AND STANDING OR

RUNNING WATER IN THE WORK AREA DOES NOT RELIEVE THE CONTRACTOR FROM MEETING THE

SPECIFICATIONS.

TIMBER & LUMBER: SOLID SAWN TIMBER MEMBERS SHALL CONFORM TO THE REQUIREMENTS OF THE

GRADING RULES AGENCY FOR THE SPECIES, TYPE, AND GRADE SPECIFIED BELOW. GLUED-LAMINATED

MEMBERS SHALL CONFORM TO THE AMERICAN INSTITUTE OF TIMBER CONSTRUCTION (AITC) 117-2001

FOR THE COMBINATION, SPECIES, USE, AND APPEARANCE SPECIFIED BELOW.

CAPS, SILL, CLEATS -COASTAL REGION DOUGLAS FIR-LARCH ROUGH SAWN

GRADING RULES AGENCY-WWPA,WCLIB

TIMBER FABRICATION:

ALL BRIDGE MEMBERS SHALL BE FABRICATED AS SHOWN IN THE BILL OF MATERIALS OR ELSEWHERE

ON THE PLANS. HOLES FOR SMOOTH DRIFT PINS OR DOWELS SHALL BE DRILLED WITH A DRILL HAVING

A DIAMETER 1/16 INCH LESS THAN THE PIN OR DOWEL TO BE USED. HOLES NOT SHOWN AS BEING

DRILLED BEFORE TREATMENT SHALL BE DRILLED IN THE FIELD WITH A DRILL HAVING THE SAME

DIAMETER AS THE BOLT TO BE USED.

HARDWARE AND STRUCTURAL STEEL:

USE MALLEABLE IRON WASHERS AGAINST WOOD EXCEPT WHERE OTHERWISE NOTED. ALL DOWEL

PINS AND DRIFT PINS SHALL HAVE THEIR ENDS GROUND ROUND. ALL BOLTS AND NUTS SHALL

CONFORM TO ASTM A307 AND NEED NOT BE GALVANIZED UNLESS SPECIFICALLY NOTED IN THE BILL

OF HARDWARE. BOLT LENGTHS SHOWN ON THE PLANS ARE CALCULATED FOR CONNECTIONS OF

STANDARD SAWN MEMBERS. IF LUMBER OR TIMBER IS FURNISHED THAT DEVIATES FROM THE

STANDARD SAWN DIMENSIONS, THE CONTRACTOR SHALL BE RESPONSIBLE TO FURNISH BOLTS WITH

THREAD LENGTHS SUFFICIENT TO MAKE THE CONNECTIONS AS SHOWN ON THE PLANS, WITH 1"

MAXIMUM THREAD EXTENSION BEYOND THE NUT WHEN TIGHT. UNLESS OTHERWISE SHOWN, EXTRA

WASHERS SHALL NOT BE USED TO COMPENSATE FOR THREAD LENGTH DEFICIENCY.

FIELD TREATMENT:

ALL CUTS, HOLES, AND ABRASIONS MADE IN THE LUMBER AFTER TREATMENT, SHALL BE GIVEN TWO

COATS OF COPPER NAPTHENATE, A.W.P.A. STD P8 AND P9, TYPE A OR TYPE C SOLVENT.

BACKFILL:

BACKFILL THE ABUTMENTS IN ACCORDANCE WITH SECTION 206. TO PREVENT DAMAGE TO THE

TREATED TIMBER, NO ROCK OVER 3" IN DIAMETER SHALL CONTACT THE TIMBER. ADDITIONAL FILL IF

NEEDED IS AVAILABLE FROM THE CUTSLOPES OF THE RIP RAP STOCKPILE

TREATMENT: PRESERVATIVE TREATMENT SHALL BE IN ACCORDANCE WITH THE CURRENT AMERICAN

WOOD PROTECTION ASSOCIATION (AWPA) SPECIFICATIONS USING THE TREATMENT MATERIALS LISTED

BELOW. TREATMENT WILL COMPLY WITH THE REQUIREMENTS OF THE CURRENT EDITION OF WESTERN

WOOD PRESERVERS INSTITUTE (WWPI) "BEST MANAGEMENT PRACTICES FOR THE USE OF TREATED

WOOD IN AQUATIC ENVIRONMENTS". USE ONE OF THE TREATMENTS BELOW

DECKING, RUNNING PLANKS

--- AWPA USE CATEGORY SYSTEM (U1) FOR USE CATEGORY 3B ABOVE GROUND - EXPOSED

(UC3B)

--- PENTACHLOROPHENOL IN LIGHT OIL (TYPE C SOLVENT)

--- COPPER NAPHTHENATE (CuN) IN LIGHT OIL (TYPE C SOLVENT)

SILLS, BACKING PLANKS, CRIBS, TIMBER WALLS

--- AWPA USE CATEGORY SYSTEM (U1) FOR USE CATEGORY 4B GROUND CONTACT - HEAVY

DUTY

--- (UC4B)

--- PENTACHLOROPHENOL IN HEAVY OIL (TYPE A SOLVENT)

--- COPPER NAPHTHENATE (CuN) IN HEAVY OIL (TYPE A SOLVENT)

FIELD TREATMENT: COPPER NAPHTHENATE (2% SOLUTION) SHALL BE FURNISHED FOR FIELD

TREATING OF WOOD. ALL ABRASIONS AND FIELD CUTS - APPROVED BY THE C.O.R. - SHALL BE

CAREFULLY TRIMMED AND GIVEN THREE BRUSH COATS OF THE FIELD TREATMENT SOLUTION. WHERE

APPROVED FIELD DRILLING OF BOLT OR NAIL HOLES IS REQUIRED, THE HOLES SHALL BE FILLED WITH

PRESERVATIVE PRIOR TO INSERTING THE FASTENERS.

AGGREGATE SURFACE COURSE: AGGREGATE FOR THE PROJECT WILL BE SUPPLIED BY THE

GOVERNMENT STOCKPILE OFF OF THE 427 ROAD APPROXIMATELY 5 MILES FROM THE BRIDGE SITE.

PLACEMENT OF THE AGGREGAT IS INCIDENTAL TO THE BRIDGE INSTALLATION
