Qualified controls contractor may perform the work with PWD Oceana DDC Office approval.

Is HFCU-13 controller replacement/programming/testing required even though the physical fan coil replacement scope is limited to HFCU-12? Yes. Per RFP. 0007

24 05/04/26

Please provide or confirm the existing HFCU-12 manufacturer, model, capacity, coil data, electrical characteristics, airflow, external static pressure, and connection sizes.

Requirements are covered in the RFP in each discipline section. For anything not covered in a discipline section, the intent is to have the same function with the new ceiling as there was with the existing ceiling. How that is accomplished is determined by the Contractor's means and methods. 0007

32 05/04/26 The RFP requires cleaning ductwork downstream of HFCU-12. Please define the limits of downstream duct cleaning, including whether cleaning is limited to ductwork served by HFCU- 12 within Rooms 19 and 20 or extends beyond those rooms.

See DUCTWORK PLAN AREA E - NEW WORK on M-205, which is part of the

REPLACE HVAC IN AIMD BUILDING

513 drawing set and included in the RFP, Part 6 - ATTACHMENTS. This shows the approximate existing location of HFCU-

12. The new HFCU-12 will be installed somewhere above the ceiling in Room 20, which is the room immediately plan West of Room 19. After installation, HFCU-12 will serve only the two diffusers in Room

19. 0007

33 5/4/2026 Is the general contractor required to hire a commissioning agent for this project? No. 0007

34 04/28/26 4 Part 3 C3030

Can minimal ceiling work be noted on mechanical drawings or do we need to include a separate architectural sheet signed/sealed by an architect? That is acceptable as long as the mechanical sheet does not become over-cluttered with other disciplines. If that happens another sheet will be required. 0007

35 04/28/26 7 Part 3 D40 Under GENERAL SYSTEM REQUIREMENTS, paragraph 3 states: "Installation drawings, shop drawings or working plans, calculations, other required pre-construction documentation and as-built drawings are not required." Please confirm that general notes on Mechanical drawings will suffice to cover minimal FP scope.

That is acceptable as long as the mechanical sheet does not become over-cluttered with other disciplines. If that happens another sheet will be required. 0007

36 04/28/26 8 Part 3 D4040 Second sentence states: "Provide up to 5 sprinklers to replace existing ones that do not function." Since visual inspection is all that's required, how are we to determine if heads don’t function? Visual inspection alone. 0007

37 04/28/26 8 Part 3 D5020 First sentence states: "Demolish existing lighting fixtures to support removal and installation of HVAC equipment demolished and provided in D30 HVAC." Please confirm that we should include replacement of all existing luminaires (19) across the two spaces. Confirmed. 0007

38 04/28/26 Please onfirm we can use pvc piping for condensate as this does not look like a plenum rated space.

The Contractor/DOR must assess the site conditions and make design decisions accordingly. 0007

39 04/28/26 Please confirm a MERV rating higher than MERV-8 is not required for filter grilles.

Do you see that requirement in the RFP? 0007

40 04/28/26 All record drawings indicate the existing ductwork and piping is sized with metric. Please confirm we can use imperial equipment sizes and transition as needed at connection points? Any submittal with metric dimensions will be immediately rejected. 0007

41 05/05/26 Please confirm that a Level 2 QC/SSHO os reuqired of this contract since there are no specifications This is answered in the RFP. 0007

43 05/05/26 Will a QC & site specific AP Plan be required to be submitted under this contract? As required. 0007

44 05/05/26

Please further clarify the limitations/expectation of duct cleaning scope. RFP states to clean ductwork downstream of existing HFCU-12. However, exsiting downstream HFCU-12 duct is called to get demoed in support of the new HFCU-12 reloaction. Meanwhile the New HFCU-12 (located in adjacent room) will have a new ducted system which would not require duct cleaning. What are the limits of the duct cleanign scope?

Look at the ductwork drawing for HFCU-12, included in the RFP, and you will know the answer to your question.

45 05/05/26 Please confirm that hydronic TAB is limited to the HFCU-12 balancing valve and does not include the connected air system or pumps.

Hydronic TAB is required to the extent that the performance of the new fan coil unit can be verified. 0007

46 05/05/26 21 of 173

Due to the limited scope of the project, can the number of submittals be reduced from 4, down to 3, eliminating the Interim Final Design? If you understood the purpose of the Interim

Final Submittal you would not have asked this question. The Interim Final Submittal is not an extra submittal, but a digital-only Final Submittal. Its purpose is to get everything right while everything is still digital to avoid unnecessarily printing hard copies of a Final Submittal that needs to be amended and then printed again. 0007
