2.3.3.4 Provide heating in the pipe basement or insulate the slab or both as
dictated by design computations for maintaining slab at 21 degrees C (70
degrees F).
2.4 FLOOR SLAB DEPRESSIONS
2.4.1 PURPOSE
Floor slab depressions are required in specific areas or rooms in order to:
A. Provide sloped floors to direct water into drains.
B. Insure that the floors of prefabricated rooms and access floors are level
with the corridor floor.
C. Provide clearance for equipment.
D. Provide space for the installation of shielding in certain areas.
E. Provide for special floor finishes that require a setting bed.
2.4.2 DEPTHS
2.4.2.1 For initial planning, use the following minimum required depressions:
A. Ceramic Floor Tile with Slope to Drain -- 75 mm (3 in.)
B. Quarry Tile Floor without Drain --------- 50 mm (2 in.)
C. Quarry Tile Floor with Slope to Drain --- 100 mm (4 in.)
Note: Use 75mm (3 in.) plus thickness of floor finish for VA Hospital
Building System (VAHBS) construction.
D. Terrazzo Floor -- 50 mm (2 in.)
E. X-Ray Rooms and Computerized Tomography (CT) Suites in Radiology -- 100 mm
(4 in.)
Note: Use 75 mm (3 in.) plus thickness of floor finish for VA Hospital
Building System (VAHBS) construction.
F. All Walk-in Freezers and Refrigerators -- 100 to 200 mm (4 to 8 in.)
G. Electromagnetic Interference (EMI) Shielded Rooms -- 38 mm (1 1/2 in.)
H. Central Computer Rooms 112 sq. m (1200 sq. ft) or smaller -- 300 mm (12
in.)
I. Central Computer Rooms larger than 112 sq. m (1200 sq. ft) -- 450 mm (18
in.)
Note: See Design and Construction Procedure, Topic 10, "Computer Systems" for
additional information.
J. Animal Cage Washer -- 300 to 350 mm (12 to 14 in.)
K. Cart Washer -- 300 to 350 mm (12 to 14 in.)
L. Audiology - Sound Suite/Booth (prefab. audiometric unit)--175 mm (7 in.)
2.4.2.2 The above list may not include all the areas where floor slab
depressions are required for a specific project.
