there's a BNJ (Brand Name Justification) included.

2. Are current mechanical site plans, existing chilled water and pump operating data, and the engineer's design calculations available for bidder review?

a. Yes; they have been added to this amendment as additional solicitation attachments.

3. Will the integration with the Building Management System (BMS) be performed by a separate controls contractor, or is it expected to be included as part of the equipment manufacturer's startup and commissioning scope?

a. Yes, the unit is just required to be compatible. A separate contract will include installation.

4. Specification Section 0001, Mechanical Scope Item D states that BACnet-compliant controls shall be provided for connection to the existing Automated Logic Energy Management System (EMS). Please clarify whether the mechanical contractor is to include all controls hardware, programming, integration, commissioning, and associated costs required for a complete BAS controls package in our bid, or if these services will be provided by the Owner's existing Automated Logic controls contractor. Additionally, please identify the party responsible for system integration and point-to-point checkout.

a. The unit Just needs to be compatible to receive a future installation

5. Please confirm whether the facility currently has an Owner-retained chemical water treatment contractor responsible for the chilled water system. If an existing contractor is in place, please clarify the extent of the mechanical contractor's responsibilities regarding water testing, chemical treatment, startup assistance, and any required coordination. If no contractor exists, please provide the required scope of chemical treatment to

a. Historically, we have used Debonair on a quarterly PM water schedule per manufacturer’s specs.

7. The solicitation includes requirements related to preventive maintenance and repairs outside the scope of preventive maintenance. Since this procurement is for the replacement of a 60-ton chiller and installation of two (2) new circulating pumps, please clarify how the preventive maintenance requirements apply to this project. Specifically, is preventive maintenance included within the scope of this solicitation, or were these requirements included in error from another contract?

a. Preventive maintenance language was written to cover refilling and readjusting water chemical levels once the system is opened. Both chillers and pumps can be independently be isolated. However, once chillers, pumps, and piping is removed for the system there will be an imbalance with water treatment loss as well as air introduced into the system. We are requesting the system to be operational and within specs once complete.

8. Unit Capacity: The SOW notes that Chiller #2 was replaced in late 2025. Was the unit installed for Chiller #2 also a 60-ton unit similar to the current requirements for Chiller #1?

a. Chiller specs listed in the statement of work for chiller 1 is an exact replicate of chiller 2 replaced in 2025 chiller.

9. Previous Scope: Regarding the Chiller #2 project, could you clarify if that contract was strictly for a full replacement (like the current SOW) or if it involved an emergency repair?

a. Chiller 2 was a complete replacement unit.

10. Can the Government please confirm whether the concrete equipment pad already exists and is suitable for installation of the new 60-ton Daikin chiller, or is the contractor responsible for providing and constructing a new concrete pad as part of this project?

a. Concrete pad is fully in tact and ready for use.
