4.3 PARTITIONS
4.3.1 METAL STUD PARTITIONS
For general interior partition framing, use 100 mm (4 in.) metal studs. Use
double row of 100 mm (4 in.) studs between adjacent X-ray rooms (with lead
shielding between rows of studs) and 150 mm (6 in.) studs for other walls of
X-ray rooms. Isolated power units require thicker walls, generally 150 to 200
mm (6 to 8 in.), depending on size of units. Therefore, use nominal 150 mm (8
in.) partitions for surgical operating rooms until completion of design
development determine a more precise size. Certain recessed electric panels
outside of electrical closets may require walls thicker than usual;
coordinate with Project Electrical Engineer. For walls with piping and other
special requirements, use other sizes or systems as appropriate.
4.3.2 STRUCTURAL DESIGN
Coordinate with Structural Engineer for design of partitions supporting wall-
hung equipment and TV support brackets, and for wind-load design of exterior
walls.
4.3.3 GYPSUM WALLBOARD
4.3.3.1 GENERAL
Where gypsum wallboard is called for, use 16 mm (5/8 in.) thick Type X gypsum
board, except for special conditions.
4.3.3.2 LEAD-LINED PARTITIONS
Use lead-lined gypsum wallboard for shielding of X-ray rooms. See
Architectural Standard Details 13091-1.dwf and 13091-2.dwf for lead
protection required. Radiation Therapy rooms will require services of a
registered physicist to establish the shielding protection required. (See
Article 5.11, "RADIATION THERAPY", below for shielding of these rooms.)
4.3.3.3 HEIGHT OF GYPSUM BOARD
4.3.3.3.1 See VA Master Construction Specifications, Section 09260, Paragraph
3.1, for height of gypsum wallboard on metal stud partitions in most
applications.
4.3.3.3.2 In addition, extend one layer of gypsum board from floor to
underside of structure above on partitions enclosing isolation room or suite.
4.3.4 SECURITY PARTITIONS
Partitions housing service windows of pharmacy, agent cashier, and credit
union must be of solid masonry or other special construction to provide
security. See Design and Construction Procedures (PG-18-3), Topic 14,
"Security".
4.4 FINISHES
4.4.1 VA GUIDE TO ROOM FINISHES
Interior finishes are prescribed in VA Program Guide PG-18-14, Room Finishes,
Door and Hardware Schedule. The project management team must review any
deviation from this document prior to start of construction document phase.
