1. CENTRAL HEATING PLANT DESCRIPTION

THE PROPOSED MAINTENANCE AUGMENTATION TEAM (MAT) BUILDING CENTRAL HEATING PLANT

CONSISTS OF 2 CONDENSING TYPE NATURAL GAS FIRED BOILERS, ASSOCIATED BOILER

CIRCULATION PUMPS, AND SYSTEM CIRCULATION PUMPS, ALL SPECIFIED FOR REPLACEMENT AS

PART OF THIS PROJECT. THE CENTRAL HEATING PLANT SUPPORTS TERMINAL HEATING

EQUIPMENT INCLUDING HW COILS IN AIR HANDLING UNITS, FAN COIL UNITS AND UNIT HEATERS.

AHU HV-1 PROVIDES MAKE-UP AIR FOR THE AIR EXHAUSTED BY VARIOUS GENERAL EXHAUST

FANS. THE HW COIL IN HV-1 IS SPECIFIED TO HAVE AN ENTERING AIR TEMPERATURE OF 14

DEGREES F. ACCORDINGLY, THE HYDRONIC HEATING SYSTEM MUST CIRCULATE WATER WITH A

30% PROPYLENE GLYCOL SOLUTION. THE HEATING HOT WATER SUPPLY TEMPERATURE

IS SPECIFIED TO REMAIN AS ORIGINALLY DESIGNED WHEN THE MAT BUILDING WAS

CONSTRUCTED. WITH A NOMINAL ΔT OF 20 DEGREES F, THIS LIMITS CONDENSING TO MILDER

HEATING CONDITIONS. IF, IN THE FUTURE, ALL TERMINAL HEATING EQUIPMENT IS REPLACED, IT IS

RECOMMENDED THAT THE EQUIPMENT BE SELECTED WITH PERFORMANCE (HIGHER ΔT, LOWER

FLOW RATE) TO SUPPORT A WIDER RANGE OF CONDENSING OPERATIONS

Q4. Does the oil boiler have an asbestos rating? If so, could you please provide that?
