Section 6. PUBLIC WORKS MAINTENANCE SHOP
1.
FUNCTION. The public works maintenance shop provides for the maintenance,
repair, and rehabilitation of existing installation facilities.
2.
LAYOUT. NAVFAC P-272, Part One contains layout requirements for the
public works maintenance shop in six different sizes, designated as Types A,
B, C, D, E, and F. NAVFAC P-80 contains criteria for the allowable size of
this facility in terms of the number of maintenance personnel permanently
assigned to the maintenance organization. The individual shops shall be
arranged within the overall facility to provide for efficient handling and
working conditions, and to consolidate similar mechanical and electrical
service systems. The shops shall be arranged with respect to other functional
areas in consideration of related work activities, noise control, and
cleanliness of operation. The support facilities such as central shop stores
and toilet and locker room area shall be centrally located to serve as a
buffer zone, separating the administrative areas and low-key activity shops
from the more active (noise and dirt producing) facilities. Space for internal
circulation of personnel and movement of materials shall be provided between
all shop areas. Direct access to the building exterior for each shop space
shall be provided for receiving and shipping of materials, and to avoid
interfering with the activity of another area. A central aisle for internal
circulation shall be arranged to serve both as a material handling area and a
personnel corridor.
3.

ity shall provide for clear span construction independent of interior
