HomeMy WebLinkAboutWPO202100068 Correspondence 2022-02-14 (6)GENERAL NOTES:
1) CONTECH ENGINEERED SOLUTIONS HAS AISC QUALITY CERTIFIED BRIDGE FABRICATION -
ADVANCED (MAJOR) WITH A FRACTURE CRITICAL AND SOPHISTICATED PAINT
ENDORSEMENT.
2) DESIGN IS IN ACCORDANCE WITH THE AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS.
3) MATERIALS (UNLESS NOTED OTHERWISE):
e) STRUCTURAL STEEL: ASTM A588 WEATHERING STEEL
b) BRIDGE PLANK: ASTM A653 GRADE 50 CLASS 1 (GALV)
c) STRUCTURAL BOLTS: ASTM F3125 GRADE A325 (GALV)
d) GUARDRAIL BOLTS: ASTM A307(GALV)
e) SHEET PILING: ASTM A929(GALV)
4) DESIGN LOADINGS:
e) BRIDGE DEAD LOAD PLUS 80 PSF TOTAL WEARING SURFACE.
b) VEHICLE LIVE LOAD: HL-93
MAX AVERAGE DAILY TRUCK TRAFFIC (ADTT) = 200
MAX LL DEFLECTION = LENGTH/500
c) OWNER SPECIFIED LIVE LOAD: U80
d) WIND LOADING PER AASHTO _RFD BRIDGE DESIGN SPECFICATIONS SECTION 3.8.
e) SEISMIC LOADING PER AASHTO _RFD BRIDGE DESIGN SPECIFICATIONS SECTION 3.10.
5) BRIDGE RAIL DESIGNED FOR TL-1 OR TL-2 LOADING IN ACCORDANCE WITH AASHTO LRFD
BRIDGE DESIGN SPECIFICATIONS APPENDIX A13.2 OR ONLY USED AS A GUIDE RAIL (RAIL
HAS NOT BEEN CRASH TESTED). SEE TYPICAL DETAILS FOR BIG R EXPRESS MODULAR
NON -CRASH TESTED BRIDGE RAILS FOR RAIL OPTIONS.
6) BRIDGE TO BE BUILT TO THE REQUIREMENTS OF AWS DI.5.
7) ALL EXPOSED SURFACES OF STRUCTURAL STEEL TO BE CLEANED IN ACCORDANCE WITH
STEEL STRUCTURES PAINTING COUNCIL SURFACE PREPARATION SPECIFICATIONS NO. 1,
SSPC-SPI SOLVENT CLEANING. EXPOSED SURFACES OF STEEL SHALL BE DEFINED AS
THOSE SURFACES SEEN FROM THE DECK OR FROM THE OUTSIDE OF THE STRUCTURE. ALL
OTHER SURFACES TO HAVE STANDARD MILL FINISH.
8) MAINTENANCE NOTE: CONTECH RECOMMENDS NOTAPPLYING DE-ICING OR DUST
PROHIBITIVE CHEMICALS OR SALTS TO ANY PART OF THE BRIDGE STRUCTURE. IF DE-ICING
OR DUST PROHIBITIVE CHEMICALS OR SALTS ARE APPLIED TO ANY PART OF THE BRIDGE
STRUCTURE, CONTECH WILL NOT BE RESPONSIBLE FOR ANY RESULTANT ACCELERATED
CORROSION.
9) ELASTOMERIC PADS ARE USED TO PROVIDE A LEVEL BEARING SU RFACE ONLY.
10) 12'x4-114" BRIDGE PLANKS ARE SHOP WELDED TO THE GI RIDERS AND ARE THE STRUCTURAL
DECKING SYSTEM. THE WEARING SURFACE IS ONLY TO PROVIDE A SMOOTH RUNNING
SURFACE AND NOT REQUIRED STRUCTURALLY.
11) DECK MAYBE FINISHED WITH GRAVEL, ASPHALT, CONCRETE, WOOD OR ANY OTHER
SUITABLE WEARING SURFACE MATERIALAT THE OWNERS DISCRETION. TYPICAL WEARING
SURFACE LOAD OF 80 PSF WILL ACCOMMODATE UP TO 51/4" OF GRAVEL BASE (130 PSF) OR
41/4' OF CONCRETE OR ASPHALT (150 PCF) SURFACING ABOVE THE STEEL BRIDGE DECK
PLANK CORRUGATIONS. FOR CONCRETE WEARING SURFACES CONTECH RECOMMENDS
USING CRACK CONTROL REINFORCING AND IF LATERAL SHIFTING OR UPLIFT OF THE
CONCRETE WEARING SURFACE IS A CONCERN, CONTECH RECOMMENDS ATTACHING
HEADED ANCHOR STUDS IN THE VALLEYS OF THE CORRUGATIONS.
