GENERAL NOTES AND REQUIREMENTS:

1. THE CONTRACTOR SHALL VISIT THE SITE TO OBSERVE THE EXISTING CONDITIONS PRIOR TO PLACING A BID. ALL QUESTIONS SHALL BE SUBMITTED TO THE VA FOR

RESPONSE PRIOR TO BIDDING THE WORK.

2. THIS PROJECT WILL INCLUDE, BUT NOT BE LIMITED TO THE FOLLOWING WORK ITEMS: THE EXISTING WATER HEATING UNITS FOR THE FOUR LOCATIONS SHOWN WILL BE REMOVED AND REPLACED. REMOVAL OF THE NATURAL GAS SYSTEMS WILL INCLUDE THE EXISTING GAS LINES AND REGULATORS TO THE MINIMUM POINT REQUIRED FOR NEW INSTALLATION. NEW GAS REGULATORS WILL BE INSTALLED FOR EACH NEW HEATER. REMOVAL OF HOT PIPING WILL BE AS SHOWN ON THE DOCUMENTS AND WILL BE MODIFIED AS REQUIRED FOR THE NEW INSTALLATION. THE EXISTING WATER HEATERS, STORAGE TANKS, EXPANSION TANKS AND MASTER THERMOSTATIC MIXING VALVES SHALL BE REMOVED AND REPLACED, EXCEPT AS LISTED IN THE BID ALTERNATES.

BUILDING 120 AND 129 WILL REQUIRE MINIMUM DISRUPTION TO THE EXISTING HOT WATER SYSTEM. TEMPORARY WATER HEATING UNITS WILL BE INSTALLED AS DESCRIBED IN NOTE 3 BELOW. OUTAGES FOR BUILDING 120 AND 129 SHALL BE LIMITED TO NO MORE THAN 8 HOURS AND WILL BE COORDINATED AT LEAST 2 WEEKS

IN ADVANCE WITH THE OWNER.

NEW POINT OF USE THERMOSTATIC MIXING VALVES SHALL BE INSTALLED AT THE LAVATORIES IN BUILDING 120 AS SHOWN.

3. A TEMPORARY, PORTABLE WATER HEATING UNIT SHALL BE PROVIDED FOR USE DURING THE MODIFICATIONS OF THE WATER HEATING SYSTEMS IN BUILDINGS 120 AND 129. THE UNIT SHALL BE TRAILER MOUNTED FOR EASY TRANSPORT. ONE UNIT SHALL BE UTILIZED FOR BOTH FACILITIES WITH THE CONTRACTOR'S PHASING OF WORK ARRANGED SUCH THAT THE UNIT CAN BE MOVED FROM ONE BUILDING LOCATION TO THE OTHER. REFER TO THE ELECTRICAL DRAWINGS FOR POWER SOURCE FOR THE HEATERS. THE HEATERS SHALL BE PROVIDED WITH AN ONBOARD PROPANE GAS SOURCE AND ALL REQUIRED PUMPS, CONTROLS, AND CONNECTIONS AS REQUIRED FOR PROPER OPERATION OF THE SYSTEM. THE SYSTEM SHALL BE SIZED IN SINGLE OR MULTIPLE UNITS WITH A TOTAL GAS INPUT

CAPACITY OF 400,000 BTUH MINIMUM.

4. THE BASIS OF DESIGN FOR MAJOR EQUIPMENT PROVIDED IN THIS PROJECT INCLUDE THE FOLLOWING:

a. SEMI-INSTANTANEOUS WATER HEATERS: NORITZ MODEL NCC

b. MASTER THERMOSTATIC MIXING VALVES: LEONARD TYPE TM EXPOSED MIXING VALVE

c. POINT OF USE THERMOSTATIC MIXING VALVES: ZURN AQUA-GARD

d. STORAGE TANKS: PVI VERTICAL AQUAPLEX SERIES

THE BASIS OF DESIGN EQUIPMENT SERVES ONLY AS A REFERENCE FOR THE ITEMS USED DURING THE DESIGN PHASE AND IS NOT INTENDED TO BE THE SOLE SOURCE OF ACCEPTABLE EQUIPMENT. ALL EQUIPMENT SHALL BE INSTALLED IN ACCORDANCE WITH THE MANUFACTURERS' RECOMMENDATIONS. WHERE THOSE RECOMMENDATIONS CONFLICT WITH THIS DESIGN, THE CONTRACTOR SHALL NOTIFY THE OWNERS' REPRESENTATIVE FOR DIRECTION PRIOR TO PROCEEDING WITH

THE WORK.

5. MOUNTING FRAMES FOR THE WATER HEATERS SHALL BE PROVIDED BY THE HEATER MANUFACTURER, DESIGNED SPECIFICALLY FOR THE HEATER MODEL SUPPLIED.

6. REFER TO THE SPECIFICATIONS FOR BID ALTERNATES.

7. ALL WORK SHALL BE THOROUGHLY COORDINATED WITH EXISTING CONDITIONS AND WITH OTHER TRADES. NEW WALL PENETRATIONS FOR TEMPORARY SERVICES WILL BE HELD TO A MINIMUM AND SHALL BE RETURNED TO “NEAR ORIGINAL” CONDITION WHEN TEMPORARY SERVICES ARE REMOVED.

8. THE EXISTING NATURAL GAS MAIN LINES WILL BE REUSED. NEW NATURAL GAS PRESSURE REGULATORS AND SHUTOFF VALVES WILL BE PROVIDED FOR EACH NEW WATER HEATER. WHERE LOCATED INDOORS, THE PRESSURE REGULATORS WILL BE DIRECT VENTED TO THE EXTERIOR.

9. ALL CONTROL WIRING WILL BE INSTALLED IN CONDUIT. THE MANUFACTURERS' RECOMMENDATIONS WILL BE FOLLOWED FOR CONTROL COMMUNICATIONS LINES

BETWEEN THE WATER HEATERS.

10. THE EXISTING HOT WATER RETURN PUMPS WILL BE REUSED. NEW PRIMARY AND BACKUP HOT WATER CIRCULATION PUMPS SHALL BE PROVIDED.

11. THE NATURAL GAS VENTS FROM THE INDOOR WATER HEATERS SHALL BE AS RECOMMENDED BY THE HEATER MANUFACTURER. THE VENTS SHALL BE INSTALLED IN ACCORDANCE WITH ALL CODES AND MANUFACTURERS' RECOMMENDATIONS. THE NEW VENTS SHALL FOLLOW THE ROUTING OF THE EXISTING VENTS THAT ARE REMOVED. NEW SLEEVES IN WALLS AND ROOFS SHALL BE INSTALLED IF NEW WALL OR ROOF OPENINGS ARE REQUIRED. WHERE PENETRATIONS THROUGH THE ROOF OR WALLS ARE NOT REUSED, THE CONTRACTOR SHALL REPAIR THE OPENINGS TO NEAR ORIGINAL CONDITION.

12. A TEMPORARY, SELF CONTAINED WATER HEATING SYSTEM SHALL BE PROVIDED FOR BUILDINGS 120 AND 129 TO PROVIDE DOMESTIC HOT WATER DURING CONSTRUCTION. 120 VOLT POWER WILL BE PROVIDED TO THE TEMPORARY LOCATIONS OF THE UNIT. DOWN TIME FOR THE CONNECTION OF THE TEMPORARY UNIT TO THE SERVICE PIPING SHALL BE COORDINATED WITH THE OWNERS REPRESENTATIVE. THE SAME UNIT SHALL BE USED FOR BOTH BUILDINGS AND DURING THEIR RESPECTIVE CONSTRUCTION PHASES. THE UNIT SHALL BE PROVIDED WITH AN ONBOARD PROPANE TANK ADEQUATELY SIZED FOR THE ANTICIPATED PROPANE USAGE DURING THE TIME OF CONSTRUCTION. THE UNIT IS ANTICIPATED TO BE TRAILER MOUNTED. THE TEMPORARY LOCATION SHALL BE SECURED DURING CONSTRUCTION WITH A LOCKED FENCE OR ENCLOSURE AS A PART OF THIS PROJECT. THE UNIT SHALL BE SIZED BASED ON THE HIGHER DEMAND OF BUILDING 120 AND 127. MAXIMUM DEMAND CAN BE ANTICIPATED FROM THE SIZE OF THE PERMANENT WATER HEATERS BEING INSTALLED BY THIS PROJECT. ALL REQUIRED TEMPORARY PIPING AND FITTINGS SHALL BE PROVIDED AND INSTALLED AS A PART OF THIS TASK.
