Attachment 14: Vendor Questions Amendment 002 0002

Performance period. SF 1442 Item 11 states completion within 180 calendar days after notice to proceed, while the continuation sheet states a period of performance of 11/04/2026 to 07/31/2027. Please confirm which governs completion. Neither. Block 11 notes that POP is negotiable.
Shutdown windows. Please identify the allowable outage windows for the condenser water and chilled water systems. Please also confirm whether the Government expects the contractor to furnish temporary cooling for the computer rooms during cutovers, or whether the existing piping may remain in service while the new piping is installed alongside it. EROS has backup systems to cool computer rooms, but several areas including all office spaces are conditioned via chilled water and condenser water for the chillers. The building must remain fully functional during the renovation. Heating season. Because condenser water supplies the AHU preheat coils in winter, please confirm whether condenser water cutover work is restricted to a particular season. EROS heats office spaces via condenser water. We do have an alternate system which uses the heating water piping. This system is heated by the dual cool CRAC units via heat rejection as well as a hot water generator fed by steam. Design responsibility. SOW II.c and II.d direct the contractor to "develop a design" for the heating water branches and the controls update. Please confirm whether a South Dakota licensed professional engineer's stamped design is required, and whether the Government will review and approve that design before installation. Yes, a licensed professional engineer will be required
Controls integration. Please identify the existing building automation system manufacturer and protocol (for example BACnet). Please also confirm whether the new electric actuators and the updated sequence must integrate with the existing front end. Honeywell BACnet. New actuators and sequences shall use existing front-end. Pipe chase. The reference drawings route new piping through a new chase in office 1414. Please confirm whether the chase construction and office rearrangement are part of the contract scope. Yes, this is part of the scope
Existing insulation. Please advise whether a hazardous materials survey exists for the existing piping insulation, and whether any asbestos-containing material is known. There are no hazardous materials expected to be found. EROS has had testing done throughout the building and the pipe insulation in question has never been an issue.
