existing buildings where it would be impracticable to install a flush floor.
Floor finish shall be non-slip quarry tile on tile setting bed. Floor
insulation shall be load bearing type. For freezer spaces on grade or above
grade with fill, provide floor heating system beneath floor insulation to
prevent frost formation and subsequent floor heaving.
5.13.1.4 CEILING SPACE ENCLOSURE
Enclose ceiling space above refrigerator/freezer along corridors and finished
rooms with finish materials as required from top of refrigerator/freezer up
to finished ceiling. Do not locate compressor on top of refrigerator or
freezer.
5.13.1.5 SPACE FOR COOLING SYSTEMS
Coordinate with Mechanical Engineer to provide appropriate space for
refrigeration cooling systems. See HVAC Design Manual, Article 4.11.4 for
guidance.
5.13.1.6 ENTRY TO FROZEN FOOD FREEZERS
Provide entrance to frozen food freezer through a refrigerator of higher
temperature.
5.13.2 MORTUARY REFRIGERATORS
5.13.2.1 TYPES
Provide prefabricated walk-in type mortuary refrigerators, except at small
facilities where self-contained mortuary refrigeration units are specifically
requested.
5.13.2.2 DESIGN AND CONSTRUCTION
Walk-in-type mortuary refrigerators shall be built as described above for
kitchen refrigerators and freezers except:
5.13.2.2.1 Door shall be standard 1200 mm (48 in.) width.
5.13.2.2.2 Install mortuary refrigerators in existing buildings so that the
finished floor levels are the same. This shall be accomplished by installing
such a prefabricated refrigerator enclosure, minus the enclosure floor,
directly upon the floor slab. Seal the enclosure perimeter against air and
waste leakage, and, where required by climate or location, place insulation
with vapor barrier below the slab to avoid condensation.
5.14 SURGERY
A. See VA Design Guides, Surgical Series, for a comprehensive graphic
consolidation of VA design criteria for surgery, as well as a detailed
narrative of the functional assumptions upon which the criteria are based.
Additional details of criteria are found in the documents described in
paragraph 1.2 above.
B. For neurological operating rooms, see Paragraph 5.5 above for
electromagnetic shielding.
5.15 TB (TUBERCULOSIS) SPACES
A. See Tuberculosis Facility Guidance in the Technical Information Library
for a summary of technical requirements for addressing tuberculosis, and a
