ventilating units, return and exhaust fans, circulating pumps, and energy recovery
equipment. Provide catalogue cuts for all selected equipment;
c. Ensure coordination with electrical, plumbing, and steam generation
disciplines by compiling the pertinent information required by them. Distribute
information, such as normal and emergency power requirements, steam
consumption for all HVAC and Kitchen/Sterilizer equipment, make-up water
requirements, to the respective trades.;
d. Submit 1:100 (1/8 inch) scale HVAC floor plans for typical areas showing at
least main supply, return, and exhaust air ductwork with sizes based on the
up-dated calculations. Illustrate duct and ceiling clearances, where ductwork cross,
with 1:50 (1/4 inch) scale local sections. Indicate ductwork, regardless of sizes
and/or complexity of layout and show 150 mm (6 inch) and larger piping in double
line. Indicate individual room air distribution and temperature control arrangement
for a representative sample of typical spaces, such as patient bedrooms, operating
suite, laboratory areas, conference rooms, etc. on duct and piping layouts. Provide
separate floor plan drawings for layouts of air distribution and piping systems.
e. Provide updated, 1:50 (1/4 inch) scale, typical mechanical equipment room
plans with resolution of review comments made during previous submission;
f. Update the typical schematic and riser diagrams for air handling systems
and hydronic systems by providing quantities and sizes to reflect the latest
engineering calculations. Show locations of all exhaust fans. Also show the
locations of all major components, with respect to the building floor and each other;
g. Perform a sound/acoustic analysis to ensure that the noise generated by the
air handling units and the fans are in compliance with the VA HVAC Design Manual;
h. Provide demolition drawings indicating scope of work for demolition;
I
Show required HVAC work associated with phasing plan;
j. Show the extent of the outside chilled water and condenser water piping.
Clearly show how the piping shall be laid in tunnels, trenches, or by direct burial;
k. Update the schematic control diagrams for each type of typical air and
hydronic system used for development in previous submission by providing written
description of the sequence of operation on the floor plans. Explain clearly the
function and role of each control device and describe the safety/alarms and normal
operating controls of each system. Provide a schedule showing electrical control
interlock of each component.
l. Detail the scope of work involved with the central Engineering Control
Center (ECC). Indicate the planned capabilities including features of energy
management and conservation. Provide a point schedule for analog/digital
input/outputs to be included in ECC; and
