Request for Proposal Number 140P4325R0023 Replace Tile Floor in Museum Restrooms at Springfield Armory National Historic Site Amendment 0001

DESCRIPTION OF AMENDMENT/MODIFICATION

The following are a list of questions received for the Solicitation Number 140P4325R0023, Replace Tile Floor in Museum Restrooms at Springfield Armory National Historic Site.

1) What are the required color and size of the required replacement tiles?

Answer: Final color and size will be approved by COR on site. Refer to Solicitation Attachment 1: “…reinstall new tile flooring of the same or similar material, size, and color…”.

2) The floors will likely need new plywood over the existing hardwood, since Schluter Ditra can't go over strip flooring. This will raise the floor height and affect how it meets the sanitary base, which may need to be removed and replaced—or modified by cutting the cove, though that risks cracking wall tile. Any top base without tile will also need replacing.

There may already be plywood, but it’s hard to tell due to the doorway heights. If it’s there, it’s likely in poor shape and could delaminate during tile removal.

Is this proposed approach acceptable?

Answer: This approach is acceptable.

3) Please confirm who will perform the demo and removal of partitions and toilets.

Answer: Any and all related or ancillary tasks necessary to replace tile floor shall be completed by the awardee under this contract.

4) It's assumed that the sub-floor in the ladies restroom ADA stall will need replacing. Are we to replace all the areas of apparent damage or all of the sub-flooring?

Answer: Yes any necessary repairs to the subfloor are required.

5) What is the current sub-floor material? There seems to be a possibility that there may be a hardwood sub-floor. Hardwood sub-floor is not suitable substrate for tile due to its movement.

Answer: This floor is over 40 years old and the Government has no record or information on the sub floor or what’s beneath the tile.

6) Is there a spec for the replacement tile?

Answer: Refer to Solicitation Attachment 1: “…reinstall new tile flooring of the same or similar material, size, and color…”. Final tile selection will be approved by COR on site.
