Q9. Specification division 25 indicated not used. Please confirm there is no DDC Control requirements. On drawing M‐101 note 8 control wiring point of disconnection. Is there a proprietary control on base?

A9. There is no DDC in the scope of the project. The control wire referenced by removals keynote 8 is associated with the control of the combustion air damper and is non‐DDC. Drawing Keynote 16 extends the wiring to the new location of the combustion air damper.

Q10. Drawing M‐101 Drawing Key note 14 Tank Heating Pump control panel. Is this panel new if so, please provide information?

A10. The intent is to have the existing Tank Heater control panel salvaged and relocated. On M‐101 make the following changes:

a. Add Removals Keynote 10 “Remove and salvage existing Tank Heating Pump Controller and enclosure to be re‐installed according to 2/M‐101”. Apply Removals Keynote 10 to the existing tank heating pump control panel shown on 1/M‐101.

b. Add drawing details 6/M‐101, 7/M‐101, and 8/M‐101 to drawing M‐101. See attached sketches SK‐M1 and SK‐M2.

c. Revise Drawing Keynote 14 to read “Reinstall salvaged pump controller. Provide or reinstall modified enclosure in accordance with 6/M‐101.”

d. Install P‐1A & P‐1B in accordance with detail 8/M‐101.

Q11. Please provide basis of design or specification for the new DT‐1 & DT‐2.

A11. Basis of Design is not provided per directive from the National Guard Bureau. Products need to comply with the technical specifications and requirements shown on the drawings. DT‐1 & DT‐2 are specified in SECTION 213116 ‐ DIESEL‐DRIVE, CENTRIFUGAL FIRE PUMPS.

Q12. Is Drawing M‐101 detail 2 calls for a stainless‐steel overflow catch basin. Please provide a detail and or a basis of design.

A12. The basin should be a remote fill box of 10‐gallon (37.85 liter) capacity cabinet which provides containment of small spills during tank filling operations.

Q13. In reference to the existing fire alarm system, can say what the name of the current Notifier service company?

A13. Fire Protection Testing is our current service company.

Q14. Please advise on which electrical conduit is required. Threaded Rigid Galvanized steel or EMT. Specifications mentions both conduits?

A14. Several types of conduits are included in the project. Refer to Specification 26 05 33, Paragraphs 3.1 A and 3.1B for use of conduit types.

Q15. Just to clarify, there is a new fire alarm system expected to be installed in this building and existing to be demoed when new is accepted, please give information on the existing campus loop tie in.

A15. Currently our fire alarm is monitored by the State Police Dispatch at Bradley. Our fire alarm communicates with them via copper wire direct connection. The new system will replace the copper and communicate via radio signal.

Q16. Electric specs. 26293 Controllers for Fire Pump Drivers, specs are very detailed about controllers and do mention existing controllers, just to clarify is there any new equipment needed for the existing fire pumps?

A16. The fire pumps and fire pump controllers are existing to remain. All other equipment is existing to remain unless otherwise noted in the Fire Protection Removals Plan, Sheet F‐101. Where re‐routing and re‐location of existing equipment is not feasible, new equipment may be used.

Q17. Electric specs. 264313 Surge protection, no surge protection shown on drawings are any required?

A17. Provide Type 1 Surge Protective equipment at existing 277/480‐volt panelboard HVPH. In addition, provide surge protection for the Fire Alarm Control Panel and along the signaling line circuit for the exterior water storage tank addressable interface/monitor modules, refer to sheet F‐601

Q18. Print EP‐101 Drawing keynote 13 calls out for local disconnect and combination starter for water storage tank heater pumps, Mech. spec. 232123 has language for provide VFD’s Please clarify who is responsible for the associated electrical equipment for these pumps.

A18. Delete specification paragraph 232123.2.1.E.5 “Provide integral pump motor variable‐speed controller.”

Q19. Electric specs. 260543 Underground Ducts talks about earthwork, please clarify who is responsible for the excavation for electrical work.

A19. General Contractor is responsible for division of work tasks.

Q19. Print EP‐101 Drawing keynote 3 wiring from diesel engine battery rack to engines, is the battery rack and cables a premade assembly provided by others? Please provide clarification/ details.

A19. Existing battery cables have flexible, heavy duty cable with factory attached connectors which mechanically attach to battery terminals. The contractor must provide replacement cables between Fire Pump battery sets and Fire Pumps.

Q20. Print EP‐101 Drawing keynote 16 provide wiring from panel HUPH, please advise or clarify panel location?

A20. Keynote 16 reference to “PANEL HUPH” should be changed to “PANEL HVPH”. Panel HVPH is the existing 277/480 volt panelboard within the building. Refer to EXISTING KEYNOTE 1.

Q21. Print EP‐101 Drawing keynote 5 provide power to FAMN panel, please advise if this is being used or location?

A21. FAMN panel refers to the FIRE ALARM panel. Refer to Sheet F‐105 for location of the FIRE ALARM

PANEL.

Q22. Print EP‐101 Drawing keynote 14 provide power wiring to tank heating pump control panel, please verify that the controller is 20‐amp 208v 3 phase panel LVPH Cir. 26,28,30 and no other power required?

A22. Provide 120‐volt, 20‐amp circuit from panelboard LVPH circuit number 22 (existing unscheduled 20/1 breaker) to Pump Control panel. Refer to RFI Response SK‐M1 for pump control panel details. Combination starters must include motor contactors, motor overloads, and HOA switch. Refer to Panel Schedule for LVPH for 20/3 for pump P1A and Pump P1B branch circuit to both pump starters. Coordinate work with Mechanical Installer.
