Project scope and cost. 
 
Supply, install and Commission fresh Air, extract air systems for level.1. Fresh Air supply system to each room - Installation of 
new [in-line] fresh air fan in the roof space above each room existing filter gril e. The existing light switch and wiring wil  be 
reused to also run this new fan when the light is turned on. Insulated flexible ducting wil  be used as shown on the drawings to 
reduce noise transmission. Exhaust Air system from each room - Installation of exhaust air system as shown on the attached 
drawings. This system wil  be time clock controlled. A “silent series” in-line type fan wil  be mounted outside the rear door as 
shown on the drawings. A weatherproof cover wil  be installed over the fan - with an access panel for servicing. The first 6 
metres of ducting before the fan including the first 2 bends wil  be internally insulated to absorb any in line “airborne” fan noise. 
Balancing dampers wil  be installed for commissioning purposes. Existing supply air gril es may need to be replaced with new 
filtered gril es as the existing gril e-filter-fan assembly seems to be one single unit and may not be able to be dismantled. 
Electrical works to reposition exit light on the door. Builders work to make good where needed. Project Management.
