SCOUR CRITICAL CODE

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 LRFD BRIDGE DESIGN SPECIFICATIONS, 9TH EDITION, 2020

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

FSH 7709.56b TRANSPORTATION STRUCTURES HANDBOOK (USDA FOREST SERVICE)

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 EXISTING CULVERTS AND TIMBER MATS, INSTALLATION OF THE NEW CULVERT STRUCTURES 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.

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

"GOPHER STATE ONE CALL" ALERT SYSTEM.

SPECIFICATIONS:

SHOP DRAWINGS SHALL BE SUBMITTED FOR THE BOX CULVERT, WINGWALLS, AND HEADWALLS.

THE MAXIMUM FOUNDATION PRESSURE IS CALCULATED TO BE 588 PSF FOR SERVICE LIMIT STATE AND 917 PSF FOR STRENGTH LIMIT STATE, BASED ON GROSS WIDTH OF THE BOX.

ALL REINFORCING STEEL SHALL BE IN ACCORDANCE WITH ASTM A615, GRADE 60 (Fy=60,000 P.S.I.). ALL WELDED WIRE REINFORCEMENT (W.W.R.) SHALL BE IN ACCORDANCE WITH ASTM A1064 (Fy=70,000 P.S.I.). GALVANIZED INSERTS SHALL BE GALVANIZED PER ASTM B633-SC4. BOLTS, RODS, WASHERS, NUTS SHALL BE HOT DIP GALVANIZED OR ELECTRO

GALVANIZED PER ASTM B633-SC1.

ANY SUBSURFACE CONDITIONS OR EXISTING FOUNDATIONS ENCOUNTERED THAT ARE NOT REPRESENTED ON THE PLANS OR IN THE SPECIFICATIONS SHALL BE BROUGHT TO THE IMMEDIATE ATTENTION OF THE ENGINEER FOR THE INSPECTION AND/OR AN ALTERNATE FOUNDATION/FOOTING DESIGN.

PRECAST CONCRETE BOX CULVERT DESIGN STRENGTH SHALL BE Fc=5,000 P.S.I. MINIMUM. PRECAST CONCRETE WINGWALL DESIGN STRENGTH SHALL BE F'c=4,000 P.S.I. MINIMUM.

CONCRETE STRENGTH SHALL BE GREATER THAN 2,500 P.S.I. PRIOR TO REMOVAL FROM FORMS AND TRANSPORT.

PRECAST CONCRETE BOX CULVERT MANUFACTURING REQUIREMENTS SHALL BE IN ACCORDANCE WITH THE CURRENT ASTM C1577, AASHTO LRFD BRIDGE DESIGN

SPECIFICATIONS, AND FP-14 SECTION 552.

IT IS THE FABRICATOR'S RESPONSIBILITY TO MAKE SURE THAT THE REINFORCING STEEL ASSEMBLY (REINFORCEMENT CAGE PATTERN) SHALL NOT EXCEED 3 LAYERS OF WELDED WIRE REINFORCEMENT. MULTIPLE LAYERS SHALL NOT BE SEPARATED BY MORE THAN THE THICKNESS OF ONE LONGITUDINAL WIRE PLUS 1/4 INCH.

THE ENDS OF THE LONGITUDINAL DISTRIBUTION REINFORCEMENT SHALL NOT BE MORE THAN 2 INCHES FROM THE ENDS OF THE BOX SECTION.

CONSTRUCTION TRAFFIC OVER THE BOX CULVERT SECTION DURING CONSTRUCTION SHALL BE LIMITED TO A MAXIMUM SINGLE AXLE WHEEL LOAD OF 16,000 LBS OR TWO (TANDEM) WHEEL LOADS OF 13,000 LBS SPACED AT 4 FEET APART. THE MINIMUM EARTH COVER SHALL BE IN PLACE PRIOR TO THE DEPLOYMENT OF HEAVY EARTH MOVING EQUIPMENT LARGER THAN A D-4 DOZER WEIGHING IN EXCESS OF 12 TONS AND HAVING A TRACK PRESSURE OF 80 PSI OR GREATER CROSSING THE STRUCTURE. AT NO TIME SHALL EARTH MOVING EQUIPMENT EXCEEDING THE DESIGNED BOX CULVERT DESIGN LOADING OPERATE OVER THE BOX CULVERT STRUCTURE.

THE PRECAST BOX CULVERT SECTIONS SHALL BE MANUFACTURED USING THE WET CAST METHOD.

THE CLEAR DISTANCE OF THE END CIRCUMFERENTIAL WIRES SHALL BE NOT LESS THAN 1/2 INCH OR MORE THAN 2 INCHES FROM THE ENDS OF THE BOX SECTION.

FILL AND SEAL LIFTING HOLES IN SECTIONS AFTER PLACEMENT OF SECTIONS.

ALL EXPOSED CORNERS ON HEADWALLS AND WINGWALLS SHOWN SQUARE ON PLANS SHALL BE BEVELED WITH 1/2" TRIANGULAR MOLDINGS EXCEPT AS OTHERWISE NOTED.
