MECHANICAL GENERAL NOTES:

1. THESE NOTES APPLY TO ALL SHEETS. REFER TO PROJECT SPECIFICATIONS FOR ADDITIONAL REQUIREMENTS. WHERE A DISCREPANCY EXISTS BETWEEN THESE PLANS AND THE PROJECT SPECIFICATIONS, THE SPECIFICATION REQUIREMENTS

SHALL TAKE PRECEDENCE OVER THE DRAWINGS.

2. VERIFY THE EXISTING CONDITIONS AT THE PROJECT SITE BEFORE SUBMITTING COST PROPOSAL. BE ADVISED THAT

LOCATIONS SHOWN ARE

APPROXIMATE. AN ATTEMPT HAS BEEN MADE TO SHOW ALL PIPING, FIXTURES, DUCTWORK, AND OUTLETS. CONTRACTOR

SHALL VISIT THE SITE

TO VERIFY COMPONENTS, LOCATIONS AND SIZES SHOWN OR NOT SHOWN. ALL COMPONENTS NEED TO BE REMOVED IN THE DEMOLITION AREA UNLESS NOTED ON THE DRAWINGS. IF DEVIATION BETWEEN EXISTING CONDITIONS AND NEW

WORK IS FOUND, CONTRACTOR SHALL NOTIFY ENGINEER.

3. THESE DRAWINGS ARE NECESSARILY DIAGRAMMATIC IN NATURE. NOT ALL FITTINGS, OFFSETS, VENTS OR DRAINS ARE

SHOWN. THE

CONTRACTOR SHALL INCLUDE ALL FITTINGS, OFFSETS, VENTS, DRAINS, AND DEVICES REQUIRED TO PROVIDE A

COMPLETE AND FUNCTIONING

SYSTEM. DO NOT SCALE OFF THESE DRAWINGS.

4. IT IS MANDATORY THAT THE EXISTING BUILDING REMAIN IN CONTINUOUS AND NON-INTERRUPTED OPERATION DURING THE CONSTRUCTION. REFERENCE THE STATEMENT OF WORK (SOW) FOR PHASING REQUIREMENTS. COORDINATE

SHUTDOWNS WITH THE OWNER A MINIMUM OF 14 DAYS PRIOR TO WORK.

5. SUPPORT ALL PIPING AND EQUIPMENT FROM BUILDING STRUCTURE MEMBERS. DO NOT SUPPORT PIPING FROM OTHER PIPING, DUCTWORK, AND/OR ELECTRICAL CONDUITS. ALL COMPONENTS REQUIRING MAINTENANCE SHALL BE SUPPORTED IN SUCH A MANNER AS TO BE READILY ACCESSIBLE WITHOUT REMOVAL OF THE CEILING SYSTEM AND TO ALLOW FOR

REMOVAL FROM THE SYSTEM WHEN SUCH REMOVAL IS REQUIRED FOR MAINTENANCE.

6. TEST AND BALANCE P-4 SYSTEM UTILIZING THE BALANCING VALVE AND IMPELLER TRIMMING AS NEEDED TO ACHIEVE THE DESIRED SYSTEM FLOW RATE. RECORD FINAL MEASUREMENTS FOR HYDRONIC EQUIPMENT (HX-2 & P-4) ON PERFORMANCE DATA SHEETS INCLUDING ENTERING AND LEAVING WATER TEMPERATURES. RECORD FINAL VALVE SETTING FOR BALANCING VALVE. PROVIDE FINAL TAB REPORT WITH ALL DATA INCLUDING TAB CONTRACTOR'S

CREDENTIALS AND EQUIPMENT CALIBRATION CERTIFICATIONS.
