PROJECT SUMMARY

THE USDA RESEARCH LAB IN CORVALLIS WAS CONSTRUCTED IN 1971, EXPANDED IN 1993, AND RECENTLY HAD SEVERAL ROOFTOP UNITS REPLACED. THIS PROJECT WILL ADD A NEW LABORATORY EXHAUST FAN AND RE-BALANCE THE BUILDING AIRFLOWS TO MAINTAIN PRESSURE RELATIONSHIPS

IN LABORATORY AREAS.

THE CONTRACTOR SHALL COORDINATE CAREFULLY WITH THE LABORATORY STAFF AND FACILITIES

TEAM REGARDING THE VARIOUS BUILDING HVAC SHUTDOWNS REQUIRED TO COMPLETE THE

PROJECT.

THE ELECTRICAL DRAWINGS DETAIL THE ELECTRICAL-SPECIFIC REQUIREMENTS IN ACCORDANCE

WITH THE ABOVE.

THE FINAL CRANE LIFT PLAN SHALL BE THE RESPONSIBILITY OF THE AWARDED CONTRACTOR. THE CRANE SHALL UTILIZE WOOD OR SIMILAR TO DISTRIBUTE THE OUTRIGGER POINT LOADS WHERE

THEY ARE LOCATED OVER UNDERGROUND UTILITIES. THE CONTRACTOR SHALL BE RESPONSIBLE

FOR PREPARING THE GROUND FOR THE CRANE AND RESTORING THE SITE TO ORIGINAL CONDITION

AS AGREED-UPON AT TIME OF AWARD TO INCLUDE ANY NECESSARY REPAIRS TO SPRINKLERS,

SIDEWALKS, ASPHALT, ETC.

GENERAL:

THE STRUCTURAL CONTRACT DRAWINGS AND SPECIFICATIONS REPRESENT THE FINISHED STRUCTURE. THEY DO NOT INDICATE THE METHOD OF CONSTRUCTION. THE STRUCTURE IS DESIGNED TO BE A STABLE UNIT AS A COMPLETED WHOLE. IT IS THE CONTRACTOR'S RESPONSIBILITY TO DESIGN, ERECT AND INSPECT TEMPORARY SHORES, BRACES, ETC. TO SUPPORT THE STRUCTURE AGAINST ALL ANTICIPATED LOADS INCLUDING GRAVITY, WIND AND LATERAL EARTH PRESSURE UNTIL ITS COMPLETION. OBSERVATION VISITS TO THE SITE BY THE STRUCTURAL ENGINEER SHALL NOT INCLUDE INSPECTION OF THESE METHODS OF CONSTRUCTION.

CONSTRUCTION MATERIAL SHALL BE PLACED ON FRAMED FLOORS AND ROOFS SUCH THAT THE DESIGN LIVE

LOADS ARE NOT EXCEEDED.

WORKMANSHIP AND MATERIALS SHALL COMPLY WITH THE EDITIONS OF THE INTERNATIONAL BUILDING CODE AND TESTING STANDARDS ACCEPTED BY THE AUTHORITY HAVING JURISDICTION AND APPLICABLE AT THE TIME THE

PROJECT WAS PERMITTED.

NOTES AND DETAILS ON THE DRAWINGS TAKE PRECEDENCE OVER THE GENERAL STRUCTURAL NOTES AND TYPICAL DETAILS. WHERE NOTES AND DETAILS ON DRAWINGS AND THESE GENERAL NOTES AND TYPICAL DETAILS ARE IN CONFLICT WITH THE PROJECT SPECIFICATION, THE MOST STRINGENT SHALL APPLY. WHERE NO SPECIFIC DETAILS ARE SHOWN, CONSTRUCTION SHALL CONFORM TO SIMILAR WORK ON THE PROJECT SUBJECT TO REVIEW BY THE ARCHITECT AND ENGINEER. "TYPICAL" DETAILS ARE NOT FLAGGED ON THE DRAWINGS, BUT APPLY

UNLESS NOTED OTHERWISE.

FRAMING MEMBERS WHICH ARE NOT DIMENSIONED SHALL BE ASSUMED EQUALLY SPACED BETWEEN

DIMENSIONED POINT OF MEMBERS SUBJECT TO REVIEW BY THE ARCHITECT AND ENGINEER.

COORDINATION:

ALL DRAWINGS ARE CONSIDERED TO BE PART OF THE CONTRACT DOCUMENTS. THE CONTRACTOR SHALL BE RESPONSIBLE FOR COORDINATING THE STRUCTURAL DRAWINGS AND SPECIFICATIONS WITH THE DRAWINGS AND SPECIFICATIONS OF ALL OTHER DISCIPLINES, INCLUDING BUT NOT LIMITED TO ARCHITECTURAL, CIVIL, MECHANICAL, ELECTRICAL, FIRE PROTECTION, AND AMONG THE SUBCONTRACTORS PRIOR TO START OF CONSTRUCTION. ANY DISCREPANCIES THAT ARE FOUND SHALL BE BROUGHT TO THE ATTENTION OF THE ARCHITECT PRIOR TO START OF CONSTRUCTION. ANY WORK PERFORMED IN CONFLICT WITH THE CONTRACT DOCUMENTS OR ANY CODE REQUIREMENTS SHALL BE CORRECTED BY THE CONTRACTOR AT HIS OWN EXPENSE

AND AT NO EXPENSE TO THE OWNER OR DESIGN TEAM.

THE CONTRACTOR SHALL VERIFY ALL DIMENSIONS, ELEVATIONS AND SITE CONDITIONS PRIOR TO STARTING

CONSTRUCTION. RESOLVE ANY DISCREPANCY WITH THE ENGINEER.

COORDINATION SHALL INCLUDE, BUT NOT BE LIMITED TO, VERIFYING THE LOCATION AND WEIGHT OF ALL MECHANICAL AND ELECTRICAL EQUIPMENT, AS WELL AS, THE SIZE AND LOCATION OF ALL MECHANICAL OPENINGS IN ROOFS, FLOORS AND WALLS. UNLESS OTHERWISE NOTED ON THE DRAWINGS, DO NOT PENETRATE ANY STRUCTURAL ELEMENTS SUCH AS BEAMS, COLUMNS, WALLS, HEADERS, JAMBS, SLABS, ETC. WITHOUT PRIOR

WRITTEN APPROVAL OF THE STRUCTURAL ENGINEER.

SPECIAL INSPECTIONS:

THE OWNER WILL EMPLOY AN ICC CERTIFIED SPECIAL INSPECTOR TO PROVIDE INSPECTION OF REQUIRED ITEMS
