PLUMBING GENERAL NOTES:

1. THIS PROJECT AREA IS WITHIN AN EXISTING FACILITY CONNECTED TO CITY DOMESTIC COLD WATER AND IS

PROTECTED BY AN EXISTING REDUCED PRESSURE BACKFLOW PREVENTER.

2. THE EXISTING DOMESTIC HOT WATER SYSTEM SERVING BUILDING 6 IS CONNECTED TO WATER HEATERS HEATING THE WATER TO 140 DEGREES, IT IS ROUTED TO AN ASSE 1017 THERMOSTATIC MIXING VALVE, DELIVERING THE HOT WATER PROVIDED TO THE PROJECT AREA PLUMBING FIXTURES AT 110 DEGREES. THE

EXISTING HOT WATER SYSTEM HAS A RECIRCULATING SYSTEM WITH A CIRCULATING PUMP.

3. PLUMBING SYMBOLS AND ABBREVIATIONS SHOWN ON THIS SHEET APPLY TO ALL SHEETS.

4. ON DEMOLITION PLANS; EXISTING MECHANICAL SYSTEMS TO BE REMOVED ARE SHOWN HATCHED AND/OR

DASHED, EXISTING MECHANICAL SYSTEMS TO REMAIN ARE SHOWN LIGHT LINE WEIGHT. ON ALL OTHER

PLANS, NEW MECHANICAL SYSTEMS ARE INDICATED WITH HEAVY LINE WEIGHTS.

5. UNLESS NOTED OTHERWISE, DETAILS SHOWN WITHIN THESE DOCUMENTS ARE APPLICABLE FOR ALL

PIPING, EQUIPMENT AND DUCTWORK INSTALLATIONS WHETHER OR NOT SPECIFICALLY NOTED.

6. THE OWNER AND ENGINEER ARE NOT RESPONSIBLE FOR THE CONTRACTOR'S SAFETY PRECAUTIONS OR FOR THE MEANS, METHODS, TECHNIQUES, CONSTRUCTION SEQUENCES, OR PROCEDURES REQUIRED TO

PERFORM THIS WORK.

7. PLANS REFLECT WORK FOR REPLACING THE INTERNAL COMPONENTS OF AHU-1 AND AHU-3. AHU-3 REFLECTS THE BASE CASE. WORK RELATED TO AHU-1 TO BE PRICED AS ADDITIVE BID ITEM I.

8. PRIOR TO DEMOLITION, CONTRACTOR SHALL PERFORM LIDAR LASER SCANNING OF PROJECT MECHANICAL ROOMS TO CAPTURE LOCATION OF EXISTING EQUIPMENT, PIPING AND DUCTWORK. AFTER COMPLETION OF WORK, CONTRACTOR SHALL PERFORM ANOTHER LIDAR LASER SCAN TO CAPTURE LOCATION OF NEW EQUIPMENT, PIPING AND DUCTWORK. REFER TO DIVISIONS 01, 22 AND 23 FRONT END SPECIFICATIONS AND

SHEET AG001 FOR ADDITIONAL INFORMATION.
