AMENDMENT 0012

The purpose of this amendment is to provide clarifications to the specifications.

Continuation Page

On RFP, Part 3a, P378F CH‐53K Maintenance Hanger Replacement, Section 6 Engineering Systems Requirements, ESR D30 HVAC, Section D303001

Replace the first two paragraphs with:

Provide multiple independent high‐efficiency air‐cooled chillers for each squadron. Where space allows, evaporators are preferred to be Shell and Tube type due to water issues local to MCB Camp Lejeune. Evaporators must be provided with factory‐installed electric freeze protection.

Provide constant primary/variable secondary pumping systems on single chiller systems greater than 60 tons and on multiple chiller systems. Primary pumping may be used only on single chiller systems less than 60 tons. Keep flow through the chiller constant; do not use variable primary flow. A buffer tank must be provided on all systems to provide thermal inertia. Provide multiple chillers for each squadron where loads greater than 160 tons with each chiller sized for 50% of the total squadron cooling load.

On RFP, Part 3a, P378F CH‐53K Maintenance Hanger Replacement, Section 6 Engineering Systems Requirements, ESR D30 HVAC, Section D304006

Replace the first two paragraphs with:

For buildings with less than 60 tons of cooling load, provide a constant primary pumping system to serve the HVAC chilled water equipment throughout the facility. For buildings with more than 60 tons of cooling load, provide a constant primary/variable secondary pumping arrangement with a single primary pump per chiller for each squadron. If only one chiller is utilized for each squadron provide two primary pumps for each chiller. Each pump must be sized for 100% flow. For buildings with more than 160 tons of cooling load, provide a constant primary/variable secondary pumping arrangement with two primary pumps per chiller. In all cases, keep flow through the chiller constant.

For building less than 160 tons, provide a single secondary pump per chiller for each squadron. If only one chiller is utilized for each squadron provide two secondary pumps for each chiller. Each pump must be sized for 100% flow.

For buildings with more than 160 tons, provide three secondary pumps, for each squadron, each sized for 50% of maximum squadron flow. Two pumps must operate as duty pumps and the third must act as standby. Provide a control sequence to rotate pump duty/standby assignments monthly and equalize running hours.”
