RFI Questions and Answers – Part 2

Project 552-19-101, Upgrade HVAC to SPS in the Medical Center, Dayton VA

1. Drawing M402 has two note 10’s. Note 10 seems to be pointing to a housekeeping pad and not a flow meter. Please advise?

The Note 10 pointing to a pad should labelled Note 9. On the Chiller Isometric, this note is shown as Note 21, which should also be labelled Note 9.

2. Drawing M405 there is a note 9 on the removals which looks like a panel or something. There is no Note 9 on the drawing. Please advise.

Note 9 is to be added to the drawing – 9. Remove existing variable frequency drive that serves cooling tower, CT-4 and replace with new. Please see revised drawing with reference to Note 9.

3. M505 has a detail for Water Meter Installation but I do not see anything on drawings which reference this detail or any specification. Is this part of the bid? Please advise.

No, the detail for Water Meter Installation is to be removed.

4. M504 has a detail for an Indirect Glycol Makeup System but I do not see anything on the drawings which references this detail or any glycol associated with the project. Is this part of the bid? Please advise.

No, the detail for an Indirect Glycol Makeup System is to be removed.

5. M405 pump filtration unit 330-CWFS-4 – does this require any kind of housekeeping pad or inertial base?

Yes, the pump filtration skid is to be mounted on a 4” concrete housekeeping pad.

6. 23 65 00 – 2.1 - G. & H. Specification calls for 304 SS hot and cold-water basins, typically we would provide 301L which is what Heapy has specified for years.

Either is fine, 304 or 301L.

7. 23 65 00 – 2.1 - K. Motor out of airstream is specified. Existing towers do not have that feature. Is this required?

Yes.

8. 23 65 00 – 2.1 - L.2.b. – Will belt drive be acceptable? Existing towers are Gear Drive.

Gear drive is preferred. Belt drive should not have been included in specs.

9. 23 65 00 – 2.2.A. & B. – Specification calls for VFD to be provided by electrical contractors. Not sure what the function of the “Control Panel” will be is that required?

No response, function of control panel is detailed in section B.

10. Existing towers are 50 HP, will 50 HP selection for cooling tower be acceptable or is 40 HP the max allowable?

40 HP is max allowable due to potential changes to electrical system required by 50 HP units.

11. This project is specified for the following: ‘The system shall be a BACNet capable Direct Digital Control System utilizing electric actuation and shall be tied into the existing Hospital Automated Logic Controls Building Automation System or Johnson Controls Metasys Building Automation System, including all graphics, trends, alarms.

All new graphics provided under this contract shall match existing graphics – obtain all required graphics files from COR. Provide 14 days’ notice in advance of requiring files.’ However, during the site visit, it was noticed that the Air Handler in this project was controlled by a Tridium AX control system. Given the prior projects bidding as Tridium AX, I would assume this project would require tying into the existing Tridium AX system and not an Automated Logic Controls Building Automation System or Johnson Controls Metasys Building Automation System. Please clarify what Building Automation System the VA wishes to tie into for this project (if any) and what type of BAS system the new panels and controllers shall abide by.

The spec for these two systems was inadvertently included in the Project Manual. This project will require tying into the existing Tridium AX system.
