Question 89 Q: As per the keynotes on the mechanical controls riser diagram found on mechanical diagram 1M-805, it specifies the need to provide various components for the AC-30, 31, 32, 33, 53, and 54 (AHU) units. These components include a new FEC2610 controller, power supply, IOM panels, network cable wire, and conduit. However, the same drawing indicates a different requirement for the same AHUs (AC-30, 31, 32, 33) except AHU-53 and AHU-54, which states the need for a FAC controller instead. Due to the ambiguity in the notes and conflicting information on the drawing, please confirm which controller is utilized.

A: For all AC equipment identified, contractor shall provide new dedicated FAC2611 controllers (or approved equivalent) and all associated equipment for a fully-functioning, commissioned control system that integrates with all existing VA controls.

Question 90 Q: Please confirm the scope of work necessary for the Existing DDC Terminal Units. Is full scope of work to confirm proper operation and connection to BMS?

A: Yes. The full scope of work is for proper operation and connection to BMS.

Question 91 Q: Per the specs section 230923 – 42, it is specified that the two-way modulating valves should be of the globe pattern type. Therefore, in accordance with this requirement, we will include the globe-type control valves in our estimate for the relevant units. Are Ball valves approved as an alternate in Lieu of Globe valves?

A: Yes, Ball valves are approved as an alternate in Lieu of Globe valves.

Question 92 Q: According to the schedule, there are supposed to be 43 VFDs (Variable Frequency Drives).

However, during the planning process, we identified and located a count that differed that 43 from the schedule. Please confirm VFD counts.

A: Please refer to drawings for an accurate count on Basement, 3rd, & 4th levels for VFDs.

Question 93 Q: As indicated in mechanical drawing 1MH101A, certain AHUs are displayed within the grid area. The mechanical symbol legend specifies that equipment shown under this grid area will not be included in the contract. However, for these equipment types, there are applicable keynotes stating that the existing HVAC equipment has direct digital control (DDC). The contractor is responsible for providing a complete and functional control system by utilizing existing control components whenever possible and adding devices as necessary to monitor and control the equipment according to the construction documents. Please confirm if we are to include scope coverage of controls for equipment within the grid.

A: Yes, The contractor is responsible for providing a complete and functional control system by utilizing existing control components whenever possible and adding devices as necessary to monitor and control the equipment according to the construction documents.

Question 94 Q: According to the specifications in section 23 09 23 – 38, it is stated that the room security sensors should be equipped with a stainless-steel cover plate. However, based on the information provided, we were unable to locate the room security sensors. Please confirm count/page where these sensors can be located.

Question 95 Q: Original Mechanical Equipment Schedules are for Contractor Reference Only (1M-713 thru 1M-715). Please confirm scope/count for existing units.

A: Drawings 1M-713 thru 1M-715 are for reference only. (Contractor Reference Only)

Question 96 Q: Within the responsibility matrix for 230923 is the requirement for the control’s contractor to interface with the or the Chiller/Boiler/ Refrigerant controls. We cannot locate this Chiller/Boiler/ Refrigerant monitoring within the plan set aside from page 1M-713 that is labelled “for contractor reference only.” Within the 230923 specifications we found that for the Boiler and/or chiller controls - if not native BACnet, will require a BACnet Gateway. Please provide more information regarding these units to properly determine the scope of work.
