BLDG 284 RFI Questions with Answers.docx

1.) What type of system do you want us to base the floor replacement on? It is my understanding that the majority of the flooring was an unfilled steel panel system with one room having a wood core floor system. We can provide cement filled steel, hollow steel (like is installed now) or wood core. In terms of price, the hollow steel is most expensive, followed by the cement filled and wood core being the least expensive.

1. There have been issues with some previous wood core warping. For price, and load bearing, the cement filled steel will be preferred in most areas.

2.) Floor finish again, I understand most was high pressure laminate but some areas had carpet finish, will you specify what new areas will get High Pressure laminate and what will get the carpet finish?

A. If the carpet finish is required do you want a static dissipative finish ( see example cut sheet) and do you want the panels to come with the finish factory applied ( See attached pictures) Factory applied makes getting under the floor much faster.

2. Please see attached sheet with info on carpet vs laminate.

3.) If the floor areas are going to be utilized as an air plenum, how many perforated panels would be required?

3. Please see attached sheet with info on perforated panels.

4.) I understand that there were quite a few cable entry holes in the existing panels, I would believe that these would be required for any future application. It may be difficult to be able to quantify how many and what type would be required for future requirements? I would suggest basing the entire project as full panels without cutouts and add a quantity that would have cutouts as spares so you will have a stock pile of panels with the cutouts as you need them. We can discuss some of these options as well. We could handle the perforated panel question the same way, All solid with a stock pile of perforated panels to be used as needed.

4. Please see attached sheet with info on cable access panels.

1. Due to electronic devices not being allowed on site, is it possible to get some overview photos of each area provided by the user?

3. Installation of new flooring up to existing flooring. Equipment "not moveable" identified in photos and by room number.

4. What is the expectation for extra(spare) tiles, vented tiles, and tiles cut with a grommet for cable passthrough?

4. No additional ventilated tiles beyond the number identified on the list. Additional tiles with a gromet for pass through would be useful.

5. What weight rating would you like for the floor tiles?

5. ***Pending communication from leadership***

6. Vented tiles are categorized by the percentage of open space for the air to flow through. What percentage of open area would you like on your vented tiles?

6. comparable to current perforated tiles. *see photo

7. It was indicated that some of the rooms should be carpeted over the raised floor. Please indicate which of the rooms should be carpeted.

11. Is there a seismic bracing requirement?

11. unknown

12. Please provide the required metal framing heights for each individual room.

12. Please see attached sheet with info on floor heights.

13. Kindly identify which rooms, if any, will require metal framing or floor systems with increased load ratings.

13. Increased load ratings for loading dock area in room 111D

14. Will the contractor be responsible for relocating any government-owned property currently located within the work areas?

14. NO! The squadron will be coordinating movement of equipment and furniture.

15. During the site visit, it was mentioned that the walking ramp near Room 111 and the corridor will require repairs. Please provide detailed information on the extent and scope of this work.

15. unknown

16. Will the alleyway located outside Room 116 be authorized for use as a material laydown area and/or for placement of a dumpster for the duration of the project?

24. For the government-required phasing (Rooms 117/116 → Rooms 111 A–I → Rooms 109/113 A–D), can phases overlap to accelerate completion if the government work areas are cleared earlier than anticipated?

24. Phase overlap will need to be adjusted during construction. 117 will be a storage area for parts and pieces from other areas after flooring is completed in that room.

25. Are updated as-built drawings available from 72 ABW/CE, and will they be provided before mobilization, or must they be obtained during the site investigation?

25. Ken Cline can provide an answer to this question.
