SPECIAL CONSIDERATIONS DURING THE CONVERSION PROCESS
Service Provision. The government is responsible for providing
required electrical service to the building to support NMCI operations within that
building. As part of the detailed site survey, DoN and the NMCI Contractor will
survey all buildings to determine if additional electrical service is required.
Building Distribution. The NMCI Contractor will determine the
size of the feeder breaker and request electrical service as follows:
For the POP according to equipment load in Table D-1.
For an MC, according to Table D-2.
For an IC, according to Table D-3.
DoN will identify the feeder breaker (if existing) or adequate usable
space in a designated panel for use by the NMCI Contractor. The NMCI
contractor may provide a dedicated technical power panel (TPP) to feed the
NMCI equipment. The NMCI contractor will provide interconnection conduit and
cabling between the designated panel and NMCI Contractor TPP and equipment.
MECHANICAL. If NMCI equipment is added to an existing room
and the heat load from the equipment exceeds the ability of existing HVAC to
provide adequate cooling for that space, the NMCI Contractor will provide
additional means for cooling that space. The power to the additional HVAC
equipment will be included in the total ampacity identified by the NMCI building
space request and should be consistent with the site cooling amps information in
Appendix D. It is desirable to have the HVAC on a separate source of power,
however, if a separate source is not available, it will be provided from the TPP by
Existing HVAC. If a space is shared or utilizes building-wide
HVAC, the NMCI Contractor will provide controls if required to be able to adjust
ventilation and temperature within the NMCI space. Independent ventilation
control is desirable. The NMCI Contractor is responsible for cooling solutions in
situations where the entire building HVAC system shut down may result in
inadequate cooling in the NMCI equipment space.
Cooling Guidelines. The NMCI Contractor will design and provide
a cooling/ventilation solution to accommodate the loads identified in Appendix D.
