No. Question

1 Is there use, dispensing, or handling of flammable or combustible liquids in building 1134?

Please provide the hydraulic calculations for building 1142 sprinkler design to verify adequate reductions were taken for backflow preventers and fittings as there is only a 4 psi safety factor. This is necessary to confidently exclude a fire pump.

3 Is 1134 used for the parking, storage, or repair of motor vehicles?

Is there any fueling or dispensing of compressed natural gas or liquefied natural gas vehicles or vessels in building 1134?

Is there any hazardous materials storage or use in Bldg 1134? If yes, please provide hazardous classification, locations of storage, and maximum quantities to ensure design complies with fire and building code requirements IAW UFC 3‐600‐01.

IAW UFC 3‐600‐01, The DFPE must determine the commodity classification and maximum storage height and include this information in the contract documents when this information differs from the minimum noted in the section on "Warehouse and Storage Facilities" in this UFC. Please provide this information for the storage located under the mezzanine in building 1134 as well as for the storage in building 1142 in order to ensure the design criteria for these areas has been properly selected and applied.

RFI responses indicate to review drawings for locations of very early warning fire detection devices.

No areas are noted on the drawings indicating any very early warning devices. Please confirm there are no such areas.

Deficiency reports for 1141 and 1144 do not indicate if the fire sprinkler protection is adequate for the facility use/hazard. Is it the intention that only the specific deficiencies identified in the reports provided be corrected or is it the intention that the sprinkler system be assessed to ensure it’s appropriately designed. If the intention is to assess adequacy of existing sprinkler protection for these two buildings, please provide as‐built drawings. Also please provide information on any storage areas including storage height, storage arrangement and commodity classification IAW UFC

3‐600‐01

Can the electric utility be considered a “reliable power source” in accordance with UFC 3‐600‐01

Section 9.5.4.2?
