WITH UTILITY COMPANIES TO PERFORM THE WORK AT NO COST TO THIS PROJECT.

THE CONTRACTOR SHALL STOP WORK IMMEDIATELY AND NOTIFY THE CONTRACTING OFFICER IMMEDIATELY IF HUMAN REMAINS ARE FOUND.

THE CONTRACTOR IS RESPONSIBLE FOR REPAIRING ANY DAMAGE TO THE ACCESS ROUTE, PARKING AREA, OR OTHER ANCILLARY AREAS.

NO SPECIFIC EROSION CONTROL MEASURES HAVE BEEN DEVELOPED. THE CONTRACTOR IS RESPONSIBLE FOR THEIR EROSION CONTROL PLAN AND

PREVENTING LOSS OF SEDIMENT FROM THE SITE.

ALL EQUIPMENT SHALL BE CLEANED ACCORDING TO THE SPECIFICATIONS PRIOR TO USE. THE CONTRACTOR SHALL MAKE EQUIPMENT AVAILABLE TO THE CONTRACTING OFFICER PRIOR TO ENTRANCE TO THE JOB SITE. THE CONTRACTOR SHALL ABIDE ALL CONDITIONS OF THEIR SPILL PREVENTION

PLAN AND APPLICABLE LAW.

DESIGN DATA:

LIVE LOAD:

ESTIMATED QUANTITIES:

PREFABRICATED STEEL SUPERSTRUCTURE DESIGN MUST BE A TRUSS CONFIGURATION SIMILAR TO THAT SHOWN ON THE DRAWINGS. THE BRIDGE SHALL MAINTAIN THE LINES AND GRADES INDICATED ON THE BRIDGE PROFILE AND ELEVATION VIEWS.

THE BRIDGE CROSS-SECTION SHALL BE DETERMINED BY THE CONTRACTOR BUT SHALL PROVIDE THE WIDTH AND RAILING DETAILS INDICATED ON THE BRIDGE TYPICAL SECTION. THE CONTRACTOR SHALL DETERMINE TRUSS HEIGHT AND THE LOCATION OF THE DECK WITH RESPECT TO THE TOP AND BOTTOM

CHORDS (U FRAME VS. H FRAME). OVERHEAD LATERAL BRACING IS UNACCEPTABLE.

DESIGN:

THE PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE AND ASSOCIATED DETAILS 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.

PROVIDE CAMBER FOR 100% OF THE FULL DEAD LOAD DEFLECTION.

DEFLECTION SHALL NOT EXCEED L/500 AND SHOULD NOT INDUCE FORCES THAT EXCEED CONCRETE COMPRESSIVE STRENGTH.

SUBMIT SHOP DRAWINGS AND CALCULATIONS FOR APPROVAL. ALL SUBMITTALS MUST BE APPROVED BEFORE FABRICATION.

THE ENGINEER SHALL DESIGN THE BRIDGE FOR EITHER H5 TRUCK LOAD OR PEDESTRIAN LOADING (90PSF), WHICHEVER GOVERNS, AND SNOW AND WIND

LOADING APPROPRIATE FOR THE LOCATION THE BRIDGE WILL BE INSTALLED.

ALL DETAILS OF THE CONCRETE DECK AND REINFORCEMENT ARE THE RESPONSIBILITY OF THE CONTRACTOR AND SHALL BE INCLUDED IN THE SHOP

DRAWINGS. DECK CONCRETE AND REINFORCEMENT IS INCIDENTAL TO PAY ITEM 55504-0000.

STEEL FABRICATION:

THE PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE SHALL BE FABRICATED BY AN AISC CERTIFIED PLANT. WHEN STRUCTURAL STEEL IS TO BE WELDED, THE WELDING PROCEDURE SHALL BE IN ACCORDANCE WITH AWS D1.5 AND SHALL BE SUITABLE FOR THE GRADE OF STEEL AND INTENDED USE OR SERVICE.

PAINT ALL STEEL MEMBERS BELOW THE DECK ELEVATION WITHIN 3 FEET OF EACH END OF THE BRIDGE WITH A STANDARD 3-COAT PAINT SYSTEM.

REMAINING TRUSS MEMBERS TO BE WEATHERING STEEL. COLOR SHALL BE SIMILAR TO THE WEATHERING STEEL.

ERECTION PLAN:

THE CONTRACTOR SHALL SUBMIT AN ERECTION PLAN FOR THE PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE TO THE C.O. FOR APPROVAL 14 DAYS

BEFORE ERECTION IS SCHEDULED.

TEMPORARY SUPPORT BENTS MAY BE USED FOR THE ERECTION OF THE PREFABRICATED STEEL TRUSS BRIDGE. THE BENTS SHALL BE CRIBBING, SILLS, CONCRETE BLOCKS OR OTHER SUPPORTS AND SHALL BE PLACED WITH MINIMAL DISTURBANCE.ALL MATERIALS TO CONSTRUCT THE TEMPORARY BENTS SHALL BE REMOVED. THE SUBMITTALS SHALL INCLUDE DRAWINGS INDICATING TEMPORARY BENT LOCATIONS AND DETAILS ALSO INCLUDED, THE CONTRACTOR SHALL INDICATE THE EQUIPMENT AND METHODS PROPOSED TO INSTALL AND REMOVE THE TEMPORARY BENTS AND ERECT THE NEW PREFABRICATED STEEL TRUSS SUPERSTRUCTURE.

NOTES:

1. THE CYAN COLORED OUTLINE IS THE CLEARING LIMIT OPENING IN THE TREE CANOPY

FOR ACCESS FOR THE BRIDGE AND CRANE.

2. CLEARING LIMITS EXTEND 20 FEET EACH WAY OF CENTERLINE OF THE BRIDGE AND

TRAIL ALIGNMENT.

3. CLEARING LIMITS EXTEND 12 FEET EACH WAY OF CENTERLINE OF THE ACCESS ROAD

CENTERLINE.

4. ADDITIONAL CLEARING WIDTH THAT IS NECESSARY FOR SETTING THE BRIDGES MUST

BE APPROVED BY THE CO PRIOR TO CUTTING TREES.

5. THE YELLOW AREA CAN BE USED FOR CONSTRUCTION STAGING.

6. PUBLIC ACCESS TO THE AREA MUST BE PREVENTED BY FENCING OR OTHER MEANS.

7. THE INTENT IS FOR THE CONSTRUCTION WINDOW TO BE DURING THE SEASON THE

BEACH IS CLOSED. IF CONSTRUCTION IS OCCURING DURING THE BEACH OPEN
