DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The current HVAC system was installed in the administration when the structure was converted from housing to offices. The system is unconventional and is very difficult to maintain with offices in the basement level and on the upper level it is very hard to maintain a comfortable temperature on both levels at the same time. The system uses a high-volume air flow through very small vents throughout the building which causes a very high pitch whistling sound all the time. This is an inconvenient nuisance to some who have offices in the building. And yet others like the (white noise) in the bldg. so as not to here other conversations.
