FSH 7709.56b TRANSPORTATION STRUCTURES HANDBOOK (USDA FOREST SERVICE) TIMBER BRIDGES: DESIGN, CONSTRUCTION, INSPECTION, AND MAINTENANCE (USDA FOREST SERVICE)

NATIONAL DESIGN SPECIFICATIONS FOR WOOD CONSTRUCTION 2018

THE EXISTING STRUCTURE SHALL BE CHECKED AT THE TIME OF STARTING CONSTRUCTION TO SEE THAT ITS RELATIONSHIP TO THE PROPOSED WORK IS AS SHOWN ON THESE PLANS AND ANY DIFFERENCES REQUIRING CHANGES IN THE NEW WORK SHALL BE REPORTED TO THE PROJECT ENGINEER.

THE WORK COVERED BY THESE PLANS INCLUDES REMOVAL OF THE ENTIRE EXISTING BRIDGE, INSTALLATION OF THE NEW BRIDGE AS SHOWN HEREIN AND PER THE MANUFACTURER'S DRAWINGS AND SPECIFICATIONS, CONSTRUCTION OF THE APPROACHES TO THE LIMITS SHOWN, AND SLOPE

RESTORATION.

THE STATIONING AS SHOWN ON THESE PLANS FOR REFERENCE POINTS "A" AND "B" ARE BELIEVED TO BE CORRECT. IT SHALL, HOWEVER, BE CHECKED AT THE TIME OF STARTING CONSTRUCTION, AND IF THE STATIONING SHOWN ON THE PLANS IS INCORRECT, IT SHALL BE REPORTED TO THE ENGINEER.

THE CONTRACTOR SHALL COORDINATE ALL OF THEIR WORK AND ANY UTILITY COMPANIES RELOCATION WORK AT NO ADDITIONAL COST TO THE

PROJECT.

GENERAL NOTES:

THE CONTRACTOR SHALL NOT PERFORM IN-STREAM WORK BETWEEN APRIL 1ST THROUGH JUNE 30TH. NO IN-STREAM WORK SHALL BE PERFORMED

AFTER SEPTEMBER 15TH.

THE CONTRACTOR SHALL VERIFY WITH THE FOREST SERVICE CONTRACTING OFFICER REPRESENTATIVE THAT THE BAT SURVEY HAS BEEN

COMPLETED PRIOR TO BEGINNING CONSTRUCTION.

SPECIFICATIONS:

ALL GRADING COMBINATIONS, AND SIZE REFER TO DOUGLAS FIR UNLESS SHOWN OTHERWISE ON THE PLANS. THE DESIGN VALUES FOLLOW LRFD BRIDGE DESIGN SPECIFICATIONS. THESE ARE THE MINIMUM REQUIREMENTS. OTHER SPECIES MAY BE USED WITH APPROVAL FROM THE FOREST SERVICE CONTRACTING OFFICER REPRESENTATIVE AND AT NO ADDITIONAL COST TO THE GOVERNMENT.

GRADING:

MISCELLANEOUS:

ALL TIMBER TO BE CUT EXACT LENGTH, DRESSED TO SIZE REQUIRED AND ALL PRACTICAL FRAMING TO BE DONE PRIOR TO TREATMENT.

ALL DECK PLANKS SHALL BE PREDRILLED PRIOR TO TREATMENT.

ALL PLANK FOR DECK PANELS SHALL BE PRECISION END TRIMMED TO LENGTH WITH 1/4" UNDERLENGTH & NO OVERLENGTH TOLERANCE PERMITTED.

DECK PANELS SHALL BE ASSEMBLED WITH 3/8" DIAMETER RING SHANK DOWELS. ALL DOWELS ARE TO BE SIMULTANEOUSLY DRIVEN WITH EQUAL FORCE USING A MECHANICAL PRESS THE FULL LENGTH OF THE DECK. ENSURING ALL HEADS ARE FLUSH WITH THE SURFACE OF THE TIMBER PLANK.

MULTIPLE IMPACT TOOLS ARE NOT TO BE USED TO SET DOWELS BECAUSE OF POTENTIAL FOR WOOD FIBER RUPTURE.

SUBMIT SHOP DRAWINGS FOR BRIDGE DECK AND RAILINGS.

DECK PANELS WILL BE DELIVERED TO JOBSITE AFTER BEING FULLY ASSEMBLED AT FABRICATION PLANT.

ALL HARDWARE FOR TIMBER CONNECTIONS TO MEET ASTM A307-97 GALVANIZED TO F2329 (A153). ALL HIGH STRENGTH HARDWARE FOR RAILING AND SPREADER BEAM CONNECTIONS TO MEET ASTM F3125 GRADE A325 OR GRADE A449 GALVANIZED TO A153.

CONSTRUCTION NOTES:

THE CONTRACTOR SHALL SUBMIT A RIPRAP GRADATION TEST RESULT ACCORDING TO ASTM D5519 PRIOR TO PLACING ROCK.

DOWEL LAMINATED DECK:

TIMBER DECK PANELS ARE MARKED IN THE SHOP FOR USE IN FIELD PLACEMENT OF THE PANELS ON THE CAPS, e.g. A1, B1, C1.

PANEL "A" IS PLACED FIRST IN ITS FINAL POSITION ON THE CAPS. NEXT DRILL THE 11/16" DIA. HOLES THRU PANEL INTO CAP IN EACH END OF PANEL AT THE LOCATION SHOWN AND FASTEN THE 3/4" DIA. DM. HD. DR. SPKS. NEXT PLACE PANEL "C" SO THAT ITS UPPER SPLICE BLOCK IS DIRECTLY OVER THE LOWER SPLICE BLOCK ON PANEL "A" AND DRAW TIGHT TOGETHER. THEN DRILL THE 9/16" DIA. HOLES THRU LOWER SPLICE BLOCK AND DRIVE THE 5/8" DM. HD. DR. SPIKES IN LOCATION SHOWN. THEN DRILL HOLES THRU PANEL INTO CAP AND FASTEN THE 3/4" DM. HD. DR. SPKS. THEREAFTER, SUCCESSIVELY PLACE PANEL "B" IN THE SAME MANNER, ENSURING ALL PANELS ARE DRAWN TIGHT TOGETHER BEFORE ANY FASTENING OCCURS.

STEEL BANDING ON PANELS IS TO BE REMOVED AFTER PANELS HAVE BEEN PLACED IN THEIR FINAL POSITION ON THE CAPS.

ALL HOLES DRILLED IN THE FIELD WHERE SPIKES ARE USED ARE TO BE 1/16" SMALLER THAN THE SPIKE SIZE.

ALL HOLES DRILLED FOR BOLTS ARE TO BE 1/16" LARGER THAN BOLT SIZE.

HOLES DRILLED FOR 3/4" LAG BOLTS ARE TO BE 9/16" IN DIAMETER FOR THE THREADED PORTION OF THE BOLT AND 13/16" FOR THE SHANK.
