Drawing A101 & A300: Regarding the area of floor to receive new epoxy

flooring: What is the thickness of the existing quarry tile floor system? Epoxy

floors are about 3/16". If the quarry tile floor is not thin set, this could mean

that it is significantly thicker than the new epoxy system. If this is the case,

will the entire floor area where the tile was removed need to be filled with a

leveling product to create a flush transition with the existing to remaining

floor? if so, what product should be used.

No information is available regarding the existing quarry tile setting bed and its

depth. If the existing setting bed is deeper than a thinset, cementitious fill will be

required to pring the new epoxy floor level with the quarry tile to remain. As the

depth of this fill in unknown, we cannot specify a fill material at this time. Bidders

should assume that the tile is thinset and that fill will not be required under the base

bid.
