GENERAL NOTES:

EXCEPT WHERE OTHERWISE INDICATED ON THESE PLANS OR IN THE SUPPLEMENTAL SPECIFICATIONS, ALL MATERIALS AND WORKMANSHIP SHALL BE IN ACCORDANCE WITH THE FHWA STANDARD SPECIFICATIONS FOR CONSTRUCTION OF ROADS AND BRIDGES ON FEDERAL HIGHWAY PROJECTS, FP-14.

THE PROPOSED IMPROVEMENTS COVERED BY THESE PLANS ARE IN ACCORDANCE WITH:

AASHTO: "GUIDELINES FOR GEOMETRIC DESIGN OF LOW-VOLUME ROADS, "2ND EDITION, 2019"

AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS, 9TH EDITION, 2020

FSH 7709.56b TRANSPORTATION STRUCTURES HANDBOOK (USDA FOREST SERVICE) TIMBER BRIDGES: DESIGN, CONSTRUCTION, INSPECTION, AND MAINTENACE (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, SLOPE RESTORATION AND RIPRAP.

TRAFFIC CONTROL FOR DETOUR SHALL BE IN ACCORDANCE WITH THE CURRENT MANUAL ON UNIFORM TRAFFIC CONTROL DEVICES (MUTCD).

THE STATIONING AS SHOWN ON THESE PLANS FOR REFERENCE POINTS "A" AND "B" (CENTERLINE OF PROPOSED BRIDGE AT THE ENDS OF THE BRIDGE SLAB) 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.

FOR PROTECTION OF UNDERGROUND UTILITIES AND IN CONFORMANCE WITH PUBLIC ACT 174, THE CONTRACTOR SHALL DIAL "811" A MINIMUM OF THREE FULL WORKING DAYS, EXCLUDING SATURDAYS, SUNDAYS AND HOLIDAYS PRIOR TO BEGINNING EACH EXCAVATION IN AREAS WHERE PUBLIC UTILITIES HAVE NOT BEEN PREVIOUSLY LOCATED.

MEMBERS WILL THUS BE ROUTINELY NOTIFIED. THIS DOES NOT RELIEVE THE CONTRACTOR OF THE RESPONSIBILITY OF NOTIFYING UTILITY OWNERS WHO MAY NOT BE A PART

OF THE "MISS DIG" ALERT SYSTEM.

WATER LEVEL IS SUBJECT TO CHANGE. THE CONTRACTOR IS RESPONSIBLE FOR DETERMINING THE EXPECTED WATER LEVELS DURING CONSTRUCTION.

NO MATERIAL SHALL BE ALLOWED TO ERODE INTO THE WATER COURSE, NOR SHALL MATERIAL BE PLACED INTO THE WATER COURSE EXCEPT AS SHOWN ON THESE PLANS.

ALL EQUIPMENT SHALL BE CLEANED ACCORDING TO THE SPECIFICATIONS PRIOR TO USE ON THIS PROJECT.

THE CONTRACTOR SHALL STOP WORK IMMEDIATELY AND NOTIFY THE CONTRACTING OFFICER IF HERITAGE RESOURCES OR HUMAN REMAINS ARE ENCOUNTERED.

NO WORK SHALL BE PERFORMED ON FEDERAL HOLIDAYS OR WEEKENDS WITHOUT PRIOR APPROVAL FROM THE CONTRACTING OFFICER.

THE CONTRACTOR SHALL PERFORM ALL IN-STREAM WORK BETWEEN MAY 15TH AND SEPTEMBER 15TH.

DESIGN DATA:

THE DESIGN OF THIS BRIDGE IS BASED ON 1.2 TIMES THE CURRENT AASHTO LRFD BRIDGE DESIGN SPECIFICATION HL-93 LOADING WITH THE EXCEPTION THAT THE DESIGN TANDEM PORTION OF THE HL-93 LOAD DEFINITION SHALL BE REPLACED BY A SINGLE 60 KIP AXLE LOAD BEFORE APPLICATION OF THIS 1.2 FACTOR.

ADDITIONALLY, THE LANE LOAD PORTION IS NOT INCLUDED. THE RESULTING LOAD IS DESIGNATED HL-93 MODIFIED. LIVE LOAD DEFLECTION DOES NOT EXCEED 1/800

OF THE SPAN LENGTH.

NOTES:

ALL HARDWARE PENETRATING THE TOP OR BOTTOM EDGE OF THE DECK PLANK SHALL PASS THROUGH THE CENTER OF THAT DIMENSION.

FIELD DRILLED HOLES IN THE LOWER SPLICE BLOCK OF EACH PANEL ARE TO BE DRILLED COMPLETELY THROUGH THE BLOCK TO PREVENT SPLITTING

WHEN INSTALLING THE 5/8" DRIVE SPIKES.

THE CONTRACTOR SHALL INSTALL NELSON 8" COMPOSITE SHIMS OR EQUAL (SUPPLIED BY BRIDGE MANUFACTURER) IN ALL LOCATIONS WHERE THE TOP OF THE SPREADER BEAM DOES NOT CONTACT THE BOTTOM OF THE DECK USING MULTIPLE SHIMS AS REQUIRED TO SHIM ENTIRE BOARD WIDTH.

ONCE INSERTED, INSTALL A #8 x 1-1/2" LONG COATED DECK SCREW BEHIND EACH SHIM TO HOLD TIGHT IN PLACE. THE CONTRACTOR SHALL RE-TIGHTEN ALL NUTS ON THE LAST DAY OF CONSTRUCTION IN THE PRESENCE OF THE CONTRACTING OFFICER TO ENSURE ALL NUTS ARE PROPERLY

TIGHTENED. SET THREADS ON ALL BOLTS AT NUT WITH A CENTER PUNCH AFTER TIGHTENING.

HIGH STRENGTH (A449) DOME HEAD BOLTS DO NOT HAVE FINS UNDER THE HEAD AT THE SHANK.

FASTEN 3"x4" PAVING STRIP, S4S, TO DECK W/ (2) 60d NAILS @ 18" CENTERS. PRE-DRILL HOLES TO AVOID SPLITTING. PAVING STRIPS ARE NOT

APPLICABLE FOR BID ALTERNATIVE.

ALL TIMBER AND HARDWARE SHOWN SHALL BE PAID FOR AS: TREATED STRUCTURAL TIMBER, SUPERSTRUCTURE AND SUBSTRUCTURE.

CONTRACTOR SHOULD BE AWARE OF THE POTENTIAL TO HIT THE R.S. NAILS IN THE PREFABRICATED DECK PANELS WHEN INSTALLING THE CURB BOLTS FOR THE CURB & SCUPPER ATTACHMENT. A 3/4" HOLE SAW IS RECOMMENDED IN DRILLING THROUGH THE R.S. NAILS FOR THIS ATTACHMENT.
