9. Your supplied drawings indicate that an epoxy non-slip surface is required in front of both of the 3’ x 3’ shower areas in Bldg 124 Main restrooms, will the other double shower areas in both the East Bldg 114 (mens and women) also require and epoxy non slip coating?

9A. Bldg. 114 “East Restrooms” does not require any work since the existing base will not be replaced. Per the SOW 114 5.1.f contractor just needs to clean and seal where the base and existing floor tile meet.

10. Is there a color preference of that coating?

10a. Any coating shall can be industrial light gray pigment or color matching “AIR

FORCE BLUE”

11. How do you propose transitioning from the existing tile surface to the epoxy coated area?

11A. Contractor shall utilize industry means and methods. Prefab divider strip (Metal or Plastic) can be utilized. Numerous companies have transition detail drawing describing the epoxy to other floors. i.e. VCT, Ceramic Tile, Carpet

12. To insure a durable coating it is proposed by epoxy installer for existing tile to be removed and existing concrete smoothed out for best adherence. This will result in a depression from existing tile level to epoxy, is this acceptable? Per installer an epoxy coating can be installed over existing tiles but long-term durability scant be guaranteed.

12A. The area where the epoxy requested has a floor drain located and noted to be demo’ d and installed with new piping. Finish floor after sanitary piping will be concrete with overlay of epoxy at entrance of shower. Epoxy area will need to be contoured to floor drain.

13. The existing 4”x4” tiles will be difficult to 100% match (color) due to age of the existing material, will “close to existing” be acceptable or is a preference for a complete contrast be required? This has relevance in how much demo needs to occur on side walls tiles that may not need to occur to access existing plumbing and can influence material and labor costs to replace shower surfaces.

13A. See Govt comment from Question 3. We are not utilizing tile to match existing but rather having contractor making a transition line and start the FRP program from that point. Existing walls were either ½ or 5/8 drywall with tile so with new wall section cross section of ½ cement board with FRP shall create thickness close to existing with sealant providing the final finish. Butt joint does not need to be exact just a functional transition.
