Questions and Answers

Q1: We were able to look at a few of the Air Handling Units that are to be replaced. Please confirm if replacement will also include the isolation valves. Furthermore, please confirm that the chilled water piping, to include valves and appurtenances will be insulated.

A1: Per Statement of Work page 4, Principle Elements of Work – Mechanical, item 1 states to demolish all existing mechanical equipment, ductwork, piping, valves, appurtenances, and controls. Similarly, item 2 states to provide the demolished items and replace with new, resulting in a complete functioning system in compliance with all applicable codes. In regards to the AHUs, this would include the isolation values for both the return and supply lines. Concerning the chilled water piping, to have a complete functioning system, all chilled water piping and appurtenances would include insulating as necessary to prevent condensation. This would include any re‐insulating necessary due to the demolish phase and the tie‐in phase.

Q2: It was noticed that the exterior pipe/duct for the split AC units were different. The exterior pipe/duct for the 12K BTU unit for the Server room had its black insulation exposed, the 36K BTU unit for room 123 was encapsulated in a metal pipe, and the 2 each 36K BTU units for the Keawe Cove room were encapsulated in a PVC type of jacket/channel. Please advise on the jacket/channel type of new split units.

A2: The exterior pipe/duct for all new split AC units will following the existing type, or similar, used for the Keawe Cove room existing split AC units. Refer to the pictures taking during the site visit.

Q3: Page 6 of the Statement of Work provides requirements for DESIGN SUBMISSION. Please confirm if this is a requirement for this project.

A3: As addressed during the Pre‐Proposal Conference, the Design Submission section will be required should the new installation equipment, location, associated piping/routing, and current code requirements differs from what is existing. This will include situations where the existing location may need to be structurally reinforced to receive the new installation (i.e., soffit structure in the Keawe Cove room, boring new holes for piping/routing, etc). If the new equipment, location, and associated piping/routing are in‐kind with the existing and there are no conflicts with current code requirements, the Design Submission section is not required.

Q4: It was mentioned that Pre‐Construction Meeting requirements will be discussed after project award.

Just so we are aware of these requirements, please advise on these.

A5: After project award/NTP and prior to the start of onsite construction, a Pre‐Construction Meeting will be held with the Contractor, Contracting, Civil Engineer Squadron, and other key stakeholders from the Government. The purpose of the Pre‐Construction Meeting will be for the Contractor to present how they intend to complete the project in accordance with the contract documents. At least 2 weeks prior to the Pre‐Con, the Contractor is to submit to the Gov’t the following items as these will be agenda items of discussion: 1) Quality Control Plan to include Submittal Register and Testing/Commissioning

Register, 2) Environmental Protection Plan, 3) Safety Plan, 4) Gantt‐type Baseline Construction Schedule with sufficient detail to track progress to include Administrative items, Submittals, Onsite Work

Activities, and Closeout Activities, and 5) Schedule of Values for Progress Payment with sufficient detail to track completed items for invoice purposes. Approval or further revisions to these submittals will be made at the conclusion of this Pre‐Con. For scheduling requirements in the Technical proposal, assume

Pre‐Construction Meeting to be held no later than 4 weeks after NTP (Notice To Proceed).
