GENERAL NOTES:

AutoCAD SHX Text SPECIFICATIONS: MATERIALS AND CONSTRUCTION OF THIS STRUCTURE SHALL BE IN ACCORDANCE WITH THE STANDARD MATERIALS AND CONSTRUCTION OF THIS STRUCTURE SHALL BE IN ACCORDANCE WITH THE STANDARD SPECIFICATION FOR CONSTRUCTION OF ROADS AND BRIDGES ON FEDERAL HIGHWAY PROJECTS (FP-14) AND STANDARD STANDARD SPECIFICATIONS FOR CONSTRUCTION OF TRAILS AND TRAIL BRIDGES ON FEDERAL PROJECTS, AutoCAD SHX Text PREFABRICATED FIBERGLASS BRIDGE SUPERSTRUCTURE: PREFABRICATED FIBERGLASS SUPERSTRUCTURE DESIGN MUST BE A TRUSS PREFABRICATED FIBERGLASS SUPERSTRUCTURE DESIGN MUST BE A TRUSS CONFIGURATION SIMILAR TO THAT SHOWN ON THE DRAWINGS. THE BRIDGE CROSS-SECTION SHALL BE DETERMINED BY THE CONTRACTOR BUT SHALL PROVIDE THE WIDTH AND RAILING DETAILS INDICATED ON THE BRIDGE TYPICAL SECTION. OVERHEAD LATERAL BRACING IS UNACCEPTABLE. ALL RELATED COMPONENTS SUCH ABUTMENT FOUNDATIONS, BEARINGS, AND TIMBER ELEMENTS SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR TO FINALIZE AND CONSTRUCT. THE PREFABRICATED FIBERGLASS 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.

AutoCAD SHX Text DESIGN: THE DESIGN OF ALL PREFABRICATED FIBERGLAS BRIDGE SUPERSTRUCTURE ELEMENTS SHALL COMPLY WITH THE AASHTO LRFD THE DESIGN OF ALL PREFABRICATED FIBERGLAS 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.

AutoCAD SHX Text ERECTION PLAN: THE CONTRACTOR SHALL SUBMIT AN ERECTION PLAN FOR THE PREFABRICATED FIBERGLASS BRIDGE SUPERSTRUCTURE THE CONTRACTOR SHALL SUBMIT AN ERECTION PLAN FOR THE PREFABRICATED FIBERGLASS BRIDGE SUPERSTRUCTURE TO THE C.O. FOR APPROVAL 14 DAYS BEFORE ERECTION IS SCHEDULED. IF NECESSARY, TEMPORARY IN-STREAM SUPPORT BENTS MAY BE USED FOR THE ERECTION. THE IN-STREAM BENTS SHALL BE CRIBBING, SILLS, 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. THE CONTRACTOR SHALL INDICATE THE EQUIPMENT AND METHODS PROPOSED TO INSTALL AND REMOVE THE TEMPORARY BENTS AND ERECT THE NEW PREFABRICATED FIBERGLASS TRUSS SUPERSTRUCTURE. PRIOR TO DELIVERY, THE COMPLETE BRIDGE SYSTEM SHALL BE DRY FIT AND ALL HOLES PRE-DRILLED. ALL BRIDGE MEMBERS SHALL BE MARKED IN A WAY THAT THEY CAN BE INSTALLED IN THEIR SAME LOCATION IN THE FIELD AS THEY WERE DURING THE DRY FIT SO THAT ALL HOLES ALIGN.
