MIL-HDBK-1003/11
15.3.1.1 Definitive Designs. In general, a diesel-electric generating type
power plant should have two-level-type construction for Definitive Designs
1, 2 and 4, and one-level-type construction for Design 3. See Tables 1 and
10.
15.3.1.2 Building Extensions. Lean-to type extensions to the main
generator building to house auxiliaries and switchgear should be used to
reduce building volume.
15.3.1.3 Provisions for Future Expansion. Contract drawings of
diesel-electric generating plant buildings should provide an easily
removable end wall for future expansion and provision for removing
generating units from the building.
15.3.2 Outdoor and Semi-Outdoor Plants. Plants without walls, or with some
walls eliminated, may be feasible in warm and temperature climates thereby
reducing construction costs. Proper measures must be taken against freezing
of stationary water. Protection against wind, rain and typhoons must be
considered, together with noise control requirements and security.
Equipment that is weatherproofed for outdoor service saves costs of building
construction; however, operation and maintenance of equipment is made more
complicated and costly. Packaged, stand-alone units have their own
enclosures and are allowed in smaller sizes; however, they must meet all
other criteria. Plant site conditions should be studied and an economic
study should be conducted to determine whether indoor or outdoor housings
should be specified.
15.3.3 Arrangements.
The following features for architectural arrangements
should be considered:
a) minimize the total building area and volume where practicable,
and also maintain adequate space for installation and for subsequent
equipment servicing and replacement,
b)
centralization of electrical equipment and controls,
c)
adequate aisle and laydown space,
d)
adaptability to various makes of equipment,
e)
adaptability to definitive designs,
f)
localization of operations,
g)
ease of replacing equipment and extending the plant life,
h)
ease of plant expansion,
i) loading and unloading fuel and equipment, and parking for
automobiles and trucks,
j) toilets, lockers, showers, work shops, offices, storage, and
control rooms,
k)
equipment platforms with proper access,
