NOTE: ALL VOLUME UNIT PAY ITEMS ARE MEASURED-IN-PLACE.

TIMBER BRIDGE COMPONENTS: ALL TIMBER COMPONENT COSTS ARE INDIRECTLY INCLUDED IN

ITEM 96401

SPECIFICATIONS: MATERIALS AND CONSTRUCTION OF THIS STRUCTURE SHALL BE IN

ACCORDANCE STANDARD SPECIFICATIONS FOR CONSTRUCTION OF TRAILS AND TRAIL

BRIDGES ON FOREST SERVICE PROJECTS, US CUSTOMARY UNITS (10/30/2014) AND

STANDARD SPECIFICATIONS FOR CONSTRUCTION OF ROADS AND BRIDGES ON

FEDERAL HIGHWAY PROJECTS (FP-14).

PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE: PREFABRICATED STEEL

SUPERSTRUCTURE DESIGN MUST BE A TRUSS CONFIGURATION SIMILAR TO THAT

SHOWN ON THE DRAWINGS. THE BRIDGE SHALL MAINTAIN THE CLEARANCES ABOVE

HIGH WATER INDICATED ON THE BRIDGE ELEVATION. THE BRIDGE CROSS-SECTION

SHALL BE DETERMINED BY THE CONTRACTOR BUT SHALL PROVIDE THE WIDTH AND

RAILING DETAILS INDICATED ON THE BRIDGE TYPICAL SECTION. THE CONTRACTOR

SHALL 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. ALL RELATED DETAILS SUCH AS PROFILE, ABUTMENT DETAILS,

BEARINGS, AND TIMBER DECKING SHALL BE THE RESPONSIBILITY OF THE

CONTRACTOR TO FINALIZE AND CONSTRUCT.

THE PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE, ABUTMENT FOUNDATIONS,

AND ASSOCIATED DETAILS INCLUDING TIMBER COMPONENTS SHALL BE DESIGNED

UNDER THE DIRECTION OF A REGISTERED PROFESSIONAL ENGINEER. THE COMPLETED

DESIGN, DRAWINGS, AND SPECIFICATION PACKAGE SHALL BE SUBMITTED TO THE

CONTRACTING OFFICER FOR REVIEW AND APPROVAL.

DESIGN: THE DESIGN OF ALL PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE

ELEMENTS SHALL COMPLY WITH THE AASHTO LRFD GUIDE SPECIFICATION FOR DESIGN

OF PEDESTRIAN BRIDGES, CURRENT EDITION AND AASHTO LRFD BRIDGE DESIGN

SPECIFICATIONS, CURRENT EDITION. PROVIDE CAMBER FOR 100% OF THE FULL DEAD

LOAD DEFLECTION PLUS 1% OF BRIDGE SPAN. SUBMIT SHOP DRAWINGS AND

CALCULATIONS FOR APPROVAL AND MUST BE APPROVED BEFORE FABRICATION.

EQUESTRIAN LOAD: DESIGN DECKS ON EQUESTRIAN TRAIL BRIDGES FOR A PATCH

LOAD OF 1000 POUNDS OVER A SQUARE AREA MEASURED 4 INCHES ON EACH SIDE.

DESIGN THE ENTIRE TRAIL BRIDGE INCLUDING THE DECK, FOR THE REQUIRED

UNIFORM PEDESTRIAN LOAD IN COMBINATION WITH OTHER LOADS AS DESCRIBED IN

SECTION 82.3 (FSH 7709.56b - TRANSPORTATION STRUCTURES HANDBOOK, CHAPTER 80

- TRAIL BRIDGE DESIGN).

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), TYPE 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 D1.1 AND SHALL BE SUITABLE FOR THE GRADE OF STEEL AND INTENDED USE OR

SERVICE. OTHER STRUCTURAL WELDS MAY USE D1.1 OR D1.5 AND SHALL BE SUITABLE FOR THE GRADE OF STEEL AND INTENDED USE OR SERVICE.

HARDWARE: MALLEABLE IRON WASHERS SHALL CONFORM TO ASTM A47 GRADE 35018. SMOOTH SHANK AND DEFORMED SHANK NAILS SHALL CONFORM TO ASTM F1667. ALL BOLTS AND LAG

SCREWS SHALL CONFORM TO ANSI B18.2.1. ALL WOOD SCREWS SHALL CONFORM TO ANSI B18.6.1. ALL THREADS, SPIKES, DOWELS AND DRIFT PINS SHALL CONFORM TO ASTM A307. ALL HARDWARE

SHALL BE GALVANIZED ACCORDING TO ASTM A153.

ERECTION PLAN: THE CONTRACTOR SHALL SUBMIT AN ERECTION PLAN FOR THE PREFABRICATED STEEL 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 PREFABRICATED STEEL TRUSS BRIDGE. THE

IN-STREAM BENTS SHALL BE CRIBBING, SILLS, CONCRETE BLOCKS OR OTHER SUPPORTS AND SHALL BE PLACED WITH MINIMAL DISTURBANCE WITHIN THE STREAM. ALL MATERIALS TO CONSTRUCT

THE TEMPORARY IN-STREAM BENTS SHALL BE REMOVED. THE SUBMITTALS SHALL INCLUDE DRAWINGS INDICATING TEMPORARY BENT LOCATIONS AND DETAILS ALSO INCLUDED, THE CONTRACTOR

SHALL INDICATE THE EQUIPMENT AND METHODS PROPOSED TO INSTALL AND REMOVE THE TEMPORARY BENTS AND ERECT THE NEW PREFABRICATED STEEL TRUSS SUPERSTRUCTURE.

TIMBER & LUMBER: SOLID SAWN TIMBER MEMBERS SHALL CONFORM TO THE REQUIREMENTS OF THE GRADING RULES AGENCY FOR THE SPECIES, TYPE, AND GRADE SPECIFIED BELOW.

DECK PLANKS AND BACKING PLANKS
