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. Building Extensions. Lean-to type extensions to the main generator building to house auxiliaries and switchgear should be used to reduce building volume. 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. 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. 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 .
