"Program

The structural system consists of top chord bearing steel joists on masonry bearing walls with continuous concrete spread footings and a concrete slab on grade.
1. All ceilings and roofs are flat.
2. Non-bearing corridor and lobby walls have a one-hour (minimum) fire-resistance rating.
3. Exterior and bearing walls have a two-hour (minimum) fire-resistance rating.
4. The ceiling height of the laboratory is 15'-0", the ceiling height of the remaining first floor spaces is 8’-4", and the ceiling height of the second floor spaces is 9'-0".
5. Ceilings are used as return air plenums. All ceilings are non-rated.
6. Assume fire/smoke dampers and transfer grilles are provided as needed.
7. The space between each ceiling and floor or roof slab must be held to the minimum dimension required to accommodate light fixtures and the structural and mechanical components shown on the plans.
8. All ducts are placed below the joists.
9. Provide 8" of clearance between the bottom of all the ducts and the finished ceiling to accommodate light fixtures.
10. Parapets must extend 2'-0" above the top of adjacent roof decks.
11. The frost depth is 5'-0" below grade."
