1. THESE DRAWINGS ARE GENERALLY DIAGRAMMATIC AND DO NOT SHOW ALL DETAILS REQUIRED FOR THE COMPLETE SYSTEMS. THEY SHOULD HOWEVER BE FOLLOWED AS CLOSELY AS POSSIBLE IN THE GENERAL ARRANGEMENT AND LOCATION OF EQUIPMENT. ALL DIMENSIONS SHALL BE CHECKED AT THE BUILDING AND ALL STRUCTURAL AND FINISH CONDITIONS INVESTIGATED. THE CONTRACTOR SHALL ARRANGE HIS WORK TO MEET THESE CONDITIONS AND PROVIDE SUCH EQUIPMENT

AND ACCESSORIES AS MAY BE REQUIRED.

2. BEFORE INSTALLING EQUIPMENT, MAKE FIELD MEASUREMENTS TO INSURE THAT ALL ITEMS OF EQUIPMENT FURNISHED WILL FIT INTO THE SPACE AS SHOWN ON THE DRAWINGS. WHERE EQUIPMENT WILL NOT FIT AS SHOWN ON THE DRAWINGS, PROVIDE A DRAWING TO THE ENGINEER FOR APPROVAL WITH A PROPOSED REVISED

ARRANGEMENT BEFORE INSTALLING THE EQUIPMENT.

3. CONTRACTOR SHALL REFER TO THE SEQUENCE OF CONSTRUCTION TO DETERMINE THE EXTENT OF CONSTRUCTION REQUIRED FOR EACH PHASE OF THE PROJECT.

CONTRACTOR SHALL RESTORE ALL SYSTEMS AS OPERATIONAL AND IN SERVICE AT THE END OF EACH CONSTRUCTION PHASE.

4. PROPERLY SUPPORT ALL WORK AND EQUIPMENT INSTALLED UNDER THIS CONTRACT PLUMB AND PARALLEL WITH BUILDING LINES. STUDY ALL GENERAL, STRUCTURAL, PLUMBING, HVAC, AND ELECTRICAL DRAWINGS, SHOP DRAWINGS, AND CATALOG DATA TO DETERMINE HOW EQUIPMENT, ACCESSORIES, PIPING, FIXTURES, AND RELATED ITEMS ARE TO BE SUPPORTED, MOUNTED, OR SUSPENDED. PROVIDE ALL BOLTS, INSERTS, PIPE STANDS, BRACKETS, STRUCTURAL SUPPORTS, AND ACCESSORIES FOR PROPER SUPPORT OF EQUIPMENT FURNISHED UNDER THIS CONTRACT. COORDINATE THE ELECTRICAL WORK WITH ALL OTHER CONTRACTORS BEFORE BEGINNING WORK TO INSURE THAT THE ELECTRICAL WORK DOES NOT INTERFERE WITH OTHER WORK. LINES WHICH REQUIRE SLOPE SHALL TAKE PRECEDENCE OVER ELECTRICAL WORK. COORDINATE THIS WITH THE PLUMBING AND GENERAL CONTRACTORS.

5. ALL ELECTRICAL WORK SHALL COMPLY WITH APPLICABLE CODES AND THE GOVERNMENTAL AUTHORITIES HAVING JURISDICTION.

6. VERIFY LOCATION AND DIMENSIONS OF ALL EQUIPMENT AND COORDINATE ALL WORK PRIOR TO THE START OF CONSTRUCTION.

KEYED NOTES NEW WORK:

1. REFER TO P-001 FOR PLUMBING GENERAL NOTES.

GENERAL NOTES:

1. COORDINATE WITH THE UTILITY PROVIDER TO REPLACE THE EXISTING METER TO SUPPORT THE NEW

NATURAL GAS DEMAND AND SUPPLY PRESSURE. UTILITY PROVIDER TO REPLACE NATURAL GAS METER

AND UTILITY SUPPLY AS NECESSARY TO ACCOMMODATE. SUPPLY PRESSURE TO BUILDING SHALL BE 2.0

PSI.

2. UPSIZE EXISTING SUPPLY PIPING DOWNSTREAM TO MATCH SUPPLY SIZE INDICATED ON PLAN FOR

GENERATOR.

3. PROVIDE NEW CONNECTION AND ROUTE ON WALL SURFACE TO NEW GENERATOR LOCATION GOING

ABOVE AND AROUND THE DOOR FRAME.

4. CONTRACTOR TO REPLACE THE EXISTING PRESSURE REGULATING VALVE SERVING THE EXISTING BOILER

(300 CFH) INSIDE THE BUILDING FOR ONE THAT ACCEPTS THE NEW 2.0 PSI INLET AND REDUCES THE

PRESSURE DOWN TO THE NECESSARY RANGE OF EXISTING EQUIPMENT (ASSUMED TO BE 0.5 PSI).

5. EXISTING DIESEL FUEL TANK TO REMAIN.

6. CUT AND CAP BOTH ENDS OF UNDERGROUND DIESEL FUEL SUPPLY PIPING ABOVEGROUND. PRIOR TO

CAPPING BOTH ENDS AND ABANDONING UNDERGROUND PIPING IN PLACE, FULLY EVACUATE ALL DIESEL

FUEL FROM UNDERGROUND PIPING AND FILL PIPING WITH FLOWABLE FILL. CAP AND WATERPROOF FUEL

LINE CONNECTION AT TOP OF TANK.

7. DISCONNECT AND REMOVE ALL DIESEL FUEL SUPPLY PIPING, AND ASSOCIATED SUPPORTS, ROUTED UP

BUILDING EXTERIOR, ALONG ROOF, UP TO AND INCLUDING FINAL CONNECTION TO EXISTING GENERATOR

IN ROOM LOCATED ON ROOF. EVACUATE DIESEL FUEL FROM HOLDING TANK AT GENERATOR AND CAP AND

SEAL FUEL LINE CONNECTION. REFER TO ELECTRICAL SHEETS FOR ADDITIONAL INFORMATION.
