GENERAL NOTES:

SPECIFICATIONS:

DESIGN : AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS, CURRENT EDITION, AND AASHTO LRFD GUIDE SPECIFICATIONS FOR THE DESIGN OF

PEDESTRIAN BRIDGES, CURRENT EDITION, AND AASHTO GUIDE SPECIFICATIONS FOR DESIGN OF FRP PEDESTRIAN BRIDGES, CURRENT EDITION.

CONSTRUCTION: STANDARD SPECIFICATIONS 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.

PREFABRICATED FRP BRIDGE SUPERSTRUCTURE: PREFABRICATED FRP SUPERSTRUCTURE DESIGN MUST BE A TRUSS CONFIGURATION SIMILAR TO THAT

SHOWN ON THE DRAWINGS. MAINTAIN THE CLEARANCES ABOVE HIGH WATER TO THE BOTTOM CHORD INDICATED ON THE BRIDGE ELEVATION. FOR

THE CONTRACTOR PROPOSED CROSS-SECTION, PROVIDE THE WIDTH AND RAILING DETAILS INDICATED ON THE BRIDGE TYPICAL SECTION, AND

DETERMINE TRUSS HEIGHT AND THE LOCATION OF THE DECK WITH RESPECT TO THE TOP AND BOTTOM CHORDS (U FRAME VS. H FRAME).

OVERHEAD LATERAL BRACING IS UNACCEPTABLE. AFTER APPROVAL BY THE CO, FINALIZE CONSTRUCTION OF THE SELECTED STRUCTURE, AND

ENSURE THAT RELATED DETAILS SUCH AS PROFILE, ABUTMENT DETAILS, BEARINGS, AND TIMBER DECKING ARE CONSIDERED AND INCLUDED IN THE

DESIGN AND CONSTRUCTION.

DESIGN THE FRP BRIDGE SUPERSTRUCTURE, ABUTMENT FOUNDATIONS, AND ASSOCIATED DETAILS INCLUDING TIMBER AND CONCRETE

COMPONENTS, UNDER THE DIRECTION OF A REGISTERED PROFESSIONAL ENGINEER. SUBMIT THE COMPLETED DESIGN, SHOP DRAWINGS, CALCULATIONS AND SPECIFICATION PACKAGE TO THE CONTRACTING OFFICER FOR REVIEW AND APPROVAL.

PROVIDE CAMBER FOR 100% OF THE FULL DEAD LOAD DEFLECTION PLUS 1% OF BRIDGE SPAN.

MATERIALS: FRP BRIDGES SHALL BE FABRICATED FROM HIGH-STRENGTH E-GLASS OR E-CR GLASS AND ISOPHTHALIC POLYESTER RESIN UNLESS

OTHERWISE SPECIFIED. WEATHERING AND ULTRAVIOLET LIGHT PROTECTION SHALL BE PROVIDED BY ADDITION OF A VEIL TO THE LAMINATE

CONSTRUCTION. MINIMUM CHARACTERISTIC DESIGN STRENGTHS, PER ASTM D7290.

THE MINIMUM THICKNESS OF FRP COMPOSITE SHAPES SHALL BE AS FOLLOWS UNLESS OTHERWISE SPECIFIED: SQUARE TUBE MEMBERS (CLOSED

TYPE SHAPE) SHALL BE 0.25 IN. WIDE-FLANGE BEAMS, CHANNEL SECTIONS, AND ANGLES (OPEN TYPE SHAPES) SHALL BE A MINIMUM THICKNESS OF

0.375 IN. STANDARD PLATE SHALL BE A MINIMUM THICKNESS OF 0.375 IN.

ERECTION PLAN : SUBMIT AN ERECTION PLAN FOR THE FRP BRIDGE SUPERSTRUCTURE TO THE C.O. FOR APPROVAL 14 DAYS BEFORE ERECTION IS

SCHEDULED. IF ALLOWED UNDER THE PROJECT DESIGN CRITERIA, TEMPORARY IN-STREAM SUPPORT BENTS MAY BE USED FOR THE ERECTION OF

THE FRP BRIDGE. CONSTRUCT TEMPORARY IN-STREAM BENTS USING UNTREATED TIMBER CRIBBING, SILLS, CONCRETE BLOCKS OR OTHER

SUPPORTS THAT ARE PLACED WITH MINIMAL DISTURBANCE WITHIN THE STREAM. REMOVE ALL MATERIALS USED TO CONSTRUCT THE TEMPORARY

IN-STREAM BENTS. SUBMIT DRAWINGS INDICATING TEMPORARY BENT LOCATIONS AND DETAILS. INDICATE THE EQUIPMENT AND METHODS

PROPOSED TO INSTALL AND REMOVE THE TEMPORARY BENTS AND ERECT THE NEW FRP SUPERSTRUCTURE.

CONNECTIONS: BOLTED CONNECTIONS SHALL BE USED FOR ALL MAIN AND SECONDARY MEMBERS. HARDWARE PER PROJECT CRITERIA.

FIELD TREATMENT: FURNISH COPPER NAPHTHENATE (2% SOLUTION) FOR FIELD TREATING OF WOOD. FOR FIELD TREATING ALL ABRASIONS AND FIELD

CUTS - AS APPROVED BY THE CONTRACTING OFFICER - CAREFULLY TRIM MEMBERS AND TREAT USING THREE BRUSH COATS OF THE FIELD TREATMENT

SOLUTION. WHERE APPROVED FIELD DRILLING OF BOLT OR NAIL HOLES IS REQUIRED OR ALLOWED, FILL THE HOLES WITH PRESERVATIVE PRIOR TO

INSERTING THE FASTENERS.

TIMBER FABRICATION: SUBMIT SHOP DRAWINGS FOR ALL TIMBER BRIDGE COMPONENTS (EXCEPT TIMBER RUNNING PLANKS). SHOW ALL DIMENSIONS

AND FABRICATION DETAILS FOR ALL CUT OR BORED TIMBER. INDICATE ON SHOP DRAWINGS WHERE FIELD DRILLING OF HOLES IS REQUIRED OR

RECOMMENDED.
