| Question | Response | |
| 1 | Spec section 23 73 00/2.1/K calls for the chilled water coils to have galvanized supports. In the past it has been my experience that chilled water coils which will constantly be exposed to moisture due to condensate will have the casing deteriorate very quickly when it is galvanized steel. Should the casings be made from stainless steel? | Specification shall remain as written, requiring hot dipped galvanized steel supports |
2 Spec section 23 73 00/2.1/K calls for the chilled water coil to have copper fins if it is serving surgery suites. Please clarify which unit, if any, will be serving surgical suites. No units will serve surgical suites
3 The existing units have UV arrays. Should the replacement units be furnished with UV arrays? If so, is their purpose purely for coil cleaning or are they there for on the fly air decontamination? Do not provide the replacement units with UV arrays.
| 4 | Is it the intent to only replace the Hydronic piping and insulation from the isolation valves to the new equipment? | Provide demolition and new work of chilled and hot water piping per H4 and H7. Intent is to replace and add piping and insulation only as necessary to properly tie in new units in the course of one weekend. |
| 5 | Control System Architecture: | Specification 23 09 23 shall remain as written, allowing only approved controls manufacturers and approved Tridium Integretion contractors. |
| Third Party Interfaces: | ||

| · The existing controllers are Honeywell and are to be upgraded. | ||
| · Is another Niagara/Triduim open protocol framework with BACnet comm. Acceptable? Local contractor will be hired to perform verification testing and intergrading to existing graphic package. |
6 After the weekend AHU installed and before and ductwork is to be connected, the unit should be pressured tested before moving forward with the air distribution connection as per specification. Will there be a representative onsite to sign off on this testing? COR or approved VA representative will be available to sign off on pressure testing.
7 During the walk through there was insulation missing from some of the piping in the penthouse area. Is this to be repaired during this project? The only repairs included in this bid are those specifically listed in the bid documents.

| 15 | Due to current potentially significant tariffs being placed on the importation of building materials such as wood or steel by the current Presidential Executive Branch, if a tariff is placed after bid time and before award will the government consider a price escalation on a contract value for products such as steel or wood should the executive branch levee tariffs effecting such materials? Most of these materials would still have been Buy American compliant as the tariffs would increase pricing on all steel or wood materials, regardless of origin. | No, this is a firm fixed price contract. |

If the contractor can remove and replace the AHU over the course of a weekend (from 5:00 pm Friday evening to 5:00 am Monday morning), then no temporary cooling will be required.

Prior to commencing work, general contractor shall provide proof that a OSHA certified “competent person” (CP) (29 CFR 1926.20(b)(2) will maintain a presence at the work site whenever the general or subcontractors are present.

The site superintendent may only serve as the OSHA competent person for specific tasks such as confined space entry, scaffold work, etc, if he has specific additional OSHA training allowing him to function as the competent person for such specific tasks. |
