d. Submit 100 percent complete HVAC floor plans for all areas showing all
ductwork and piping at 1:100 (1/8 inch) scale. Indicate ductwork and piping on
separate drawings unless otherwise waived by VA. Show all duct/pipe sizes and
air/fluid quantities. Air quantities for each room and each air inlet/outlet, expressed
in cubic meters (feet) per minute, and fluid quantity, where required, in liters per
second (gallons per minute). Show all volume dampers, fire dampers, smoke
dampers, automatic control dampers, rises and drops in ductwork, air inlet/outlets,
etc., on the air distribution floor plans. Show all piping specialties, such as,
expansion loops, anchors, valves, drip assemblies, balancing fittings, etc., on the
piping floor plans. Indicate all architectural room names and numbers along with
designated smoke and smoke/fire barriers.
e. Submit 100 percent complete HVAC floor plans for all mechanical equipment
rooms with at least two cross-sections taken at right angles to each other at 1:50
(1/4 inch) scale. Show all equipment located on roof and/or grade.
f. Update smoke and fire partitions in HVAC floor plans as described under
DD1.
g. Provide 100 percent complete drawings of the outside chilled water and
condenser water distribution showing pipe sizes and insulation with plans, profile,
sections, details, and all accessories, such as, anchors, expansion loops/joints,
valves, manholes, capped and flanged connections, interface between the new and
existing work (if any). Clearly indicate interference's (if any) with the existing utilities
and/or landscape elements on outside piping layout drawings. Show rerouting any
utilities, cuttings of roads, pavements, trees, etc., and the extent of new and
demolition work. Base outside utility drawings on the study of the latest site
drawings, discussions with engineering personnel, and the actual site inspection of
the existing utility.
h. Provide 100 percent complete automatic temperature control drawings.
Clearly show all duct detectors, control valves/dampers static pressure sensors,
differential pressure control assemblies, etc., whose actual physical location is
critical for the intended sequence of operation on floor plans. For projects involving
a central Engineering Control Center (ECC) provide a point schedule with intended
analog/digital input/outputs, graphics capabilities, and requirements of the other
trades to be included in the ECC. Provide a riser diagram showing locations of all
field data gathering panels and their interface with the ECC. Show the actual
location of the ECC and peripherals on floor plans.
i. Submit 100 percent complete standard detail drawings. Edit VA details to
suit the project. Include any special details deemed useful and necessary for the
project.
j. Provide 100 percent complete HVAC demolition drawings showing clearly
the extent of demolition work. Indicate sizes of ductwork and piping to be
dismantled. Show capacities and sizes of the existing equipment to be removed.
Show clearly points of connection, disconnection, blankoffs, and deadend flanges
with isolating valves. Coordinate demolition and restoration work with other
