Section 2. MOTORIZED VEHICLE MAINTENANCE FACILITIES
Part 1. PUBLIC WORKS TRANSPORTATION OPERATIONS AND MAINTENANCE FACILITY
1.
FUNCTION. Transportation equipment maintenance facilities are required to
provide covered work areas for inspection, maintenance, and repair of all
transportation equipment assigned to an activity and, as applicable, other
tenant commands. Covered facilities are essential in the maintenance and
upkeep of the equipment fleet, in order to minimize or avoid the destructive
effects of inclement weather and to achieve maximum productivity from
maintenance personnel. For reasons of overall efficiency and economy, the
transportation maintenance and operation facilities for automotive,
construction/ weight-handling, and railroad equipment should be combined. (See
Part 3 and Part 4 of this section for criteria for construction/
weight-handling equipment shops and railroad equipment shops, respectively,
when the shops are not included with this facility.)

SPACE REQUIREMENTS.
a.
Layout. The size of the facility to be used will be governed by
the number of general repair bays needed, as computed from the tables and
procedures set forth in NAVFAC P-80, for Category Code 214-20, Automotive
Vehicle Maintenance Shop. General repair bays for this purpose are defined as
that area required for inspection, maintenance, repair, and overhaul of
transportation equipment. Several layouts for this facility, depending on the
number of general bays required, are given in NAVFAC P-272, Part One. The size
of a single general repair bay consists of a layout configuration 16 feet wide
and 30 feet long. The basic design criteria incorporates drive-through
features with two single bays end-to-end and thus results in a double general
bay 16 feet wide and 60 feet long.

In addition to the general repair bays, space is required for
direct support areas and administrative and other indirect support areas. (See
NAVFAC P-80, Category Code 214-20 for space requirements and NAVFAC P-272,
Part One, for layout of these areas.)
(2)
Repair bay support accessories for heavy construction/
weight-handling and railroad equipment differ in requirements from that of
automotive. Consideration should be given to designating the necessary repair
bay requirements for such equipment in one wing, or in a portion of one wing,
as applicable. When railroad equipment is involved, consideration must be
given to the track approach, since this can govern the location of the area
selected for heavy equipment repair. (See Category Code 218-40, Railroad
Equipment Shop, in NAVFAC P-80, for the number of repair bays with pits
required.)
(3)
Basic design features of the transportation repair facilities
are flexible, and caution should be exercised when the final design is devel-
oped to ensure a reasonable balance of general repair bays in each wing. For
example, assuming that 20 repair bays are determined as requirements to
satisfy the needs of an activity, the design should provide for a symmetrical
layout around the centrally-located administrative support area, with five
double general repair bays located in each wing rather than eight bays in Wing
1 and two bays in the opposite wing. Further, in the development of require-
ments for a specific repair facility, consideration must also be given to
