MIL-HDBK-1027/4A
4.2.5.2
Weight Handling Equipment. Monorails should comply with DM 38.01.
Conform to NAVFAC NFGS-14637 and NFGS-14622 where applicable. Provide
platforms, catwalks, access ladders, and any other provisions for inspection
and maintenance of hoists.
Obtain user and device manufacturer input regarding controls and
speed criteria for hook heights, capacities and service area. Note that
lifting a device will require more clearance than necessary for stationary
position.
4.2.5.3
Floors.
Design floor slabs along the travel path of any equipment
to withstand the heaviest wheel loads anticipated during the installation, in
compliance with criteria in MIL-HDBK-1002/2. Training equipment
incorporating motion systems will impose static and dynamic forces upon the
facility structure.
Isolate the mechanical equipment room floor slabs from the
remainder of the facility.
4.2.5.4
Roof Loads. Mechanical equipment is preferred at ground level;
however, where roof mounting is necessary, design screening in accordance
with local wind loads and directional patterns. Anticipate other roof
structure mounted accessories, such as catwalks, ladders, hoists and cranes.
4.2.6
Heating, Ventilating and Air Conditioning. Comply with
MIL-HDBK-1003/3 and refer to MIL-HDBK- 1008C for coordination with fire
protection systems. Coordinate exterior mechanical equipment location with
civil design. Locate noisy chillers and other equipment remote from occupied
spaces and as near as possible to the mechanical spaces. Shade is desirable;
however, equipment should not be located beneath trees, where it can become
clogged with leaves and debris. Distribution piping for utilities, including
refrigerant and condenser water, should enter the building only through the
mechanical room.
Avoid routing chilled water piping over computer areas
and trainer devices, to prevent damage to high cost equipment from leakage
and condensation. Provide isolation valves to facilitate maintenance without
system shutdown. Comply with NAVFAC DM-3.10 where adjacent spaces and/or
sensitive equipment cannot tolerate noise and vibration.
Ceilings may be higher than normal due to lab trainer requirements.
Accommodate appropriate airflow requirements at the trainee table working
level.
4.2.6.1
Design Conditions. Design conditions for comfort conditioning
should be determined in compliance with MIL-HDBK-1190.
4.2.6.2
Ventilation. Provide ventilation rates for occupied spaces as
required in ASHRAE STD 62. Provide thermostatically controlled forced
ventilation in mechanical, electrical, pneumatic and hydraulic spaces. Cool
pump rooms and compressor rooms by mechanical ventilation only.
4.2.6.3
Zoning, System Selection and Part Load Performance. Occupancy of
classroom areas varies drastically with respect to training schedule.
Consider each classroom/training area as a separate temperature and humidity
control zone. Provide individual temperature controls for each classroom.
Size terminal equipment to accommodate minimum as well as maximum loads.
