ADDENDUM 01

ANSWERS TO CONTRACTOR QUESTIONS:

1. Question: Q1. B211 – the existing epoxy flooring in BDOC appears to be in relatively good condition. The plan calls to remove it and replace with carpet. Removing epoxy flooring is either done by grinding or shot blasting which is a noisy and dusty process. Given the sensitive nature of this area, we suggest leaving the existing epoxy in place, applying a skim coat of material to make the floor smooth and then install the carpet. This option is cleaner, faster and less expensive than removing the epoxy.

Response: Upon further discussion, we are removing B211 from the scope of the project. See attached revised drawings.

2. Question: Q2. B212 – There are existing nose wheel lines on the floor that would be removed during the work and no mention of replacing them. Please confirm this would not be in our contract or provide clarification, layout and material if we are to include this. Plansheet A1.10 for this area shows flooring transitions at doors. The entire existing perimeter of this hangar bay slab is sealed with what appears to be Dow 890 sealant and no such transition strips exist. All the doors around the perimeter appear to have flooring of similar thickness that would not require a transition. Please confirm how to proceed.

Response: See attached revised drawings and Bid Option 01 to include repainting taxiway lines and replacing DOW 890-SL sealant at all doors openings that currently have sealant.

3. Question: Q3. B385 – the existing tile flooring joints do not align with door openings. Removing the tile and leaving a clean edge at the doorway is nearly impossible. Since the existing flooring appears to be in good repair and is bonded to the substrate, would it be possible to clean the existing tile and install the new carpet over it with transition strips at the doors?

Response: Existing floor tile shall be removed. Provide a clean edge in doorways to be covered by a transition strip prior to installing carpet tiles.

4. Question: Q4. The details 2 & 3 that show the flooring transition are not defined in any specific location. If these are to be used, please indicate which style is to be used and indicate every location they would occur. Please confirm and describe if there is existing wall base to be removed in any of these areas. It is not shown or described.

Response: Flooring transition types/locations as well as existing wall base to be removed are addressed on revised drawings.
