This project will consist of replacing three (3) existing roof -top HVAC units of 6-ton, 7.5 ton and

12.5 ton with new HVAC units. This Project also consists of replacing the one (1) split system serving classrooms A and B with two (2) new units to serve each classroom as well as installation of new ventilation system for the classrooms.

The 12.5-ton HVAC unit serves the common area, hallways, classrooms D and E, and office 6.

The 7.5-ton HVAC unit serves classrooms C and F, rest rooms, and lounge areas.

The 6-ton HVAC unit serves the conference room and offices 1 - 5.

The two new units will serve classroom A and classroom B, individually.

2. Addendum D is modified to also include the enclosed color-coded floor plan for a visual representation of the areas served by the various HVAC units. This floor plan is from the School’s tenant improvements in 2010 and is only meant for informational purposes.
