c. The Government should perform a preliminary hydraulic analysis to determine the
adequacy of the existing water supply for required fire protection. The Government may use a
recent flow test or historical data for this purpose. This analysis should not be used as the
basis for design, but for project scope definition and for budgetary cost purposes. Hydraulic
analysis needed for the design must be based on recent and accurate water supply test data,
as stated below in paragraph 2d.
d. Water Supply Flow Testing for Fire Protection. The RFP should requires that a water
supply flow test be conducted by the Design-Build contractor to determine water supply
available for the fire protection systems and for hose streams from fire hydrants. The test
must determine the static pressure and the residual pressure at a flow rate which is equal to or
greater than the combined sprinkler and hose stream demand. The test data will be used in
the hydraulic analysis and as the basis for the design of the sprinkler system, the underground
mains and the fire hydrants. However, if the Government can provide flow test data from a
recent flow test, performed near the point of connection and conducted or witnessed by a
trained engineer or technician, the requirement that the Design-Build contractor conduct a flow
test can be deleted from the RFP.
e. The RFP should provide a detailed description of the required fire sprinkler protection,
fire suppression systems and fire alarm/detection systems.
f. The Government should provide design narratives for each fire alarm system. The
narrative should state how the Design-Build contractor will design each system. The RFP
should indicate the required zoning of the fire alarm and detection systems. For non-
addressable systems, the fire alarm and detection systems should be zoned by building, by
floor and area, and by type of device.
g. The RFP should specify connection to the base-wide fire reporting system for
monitoring of the fire suppression systems, and the building fire alarm/detection system. A
detailed description of the base-wide fire reporting system should be indicated in the RFP.
h. Consider a requirement to design for future expansion.
