Re: Project

Tile installations over wood sub floors

The specifications for this job call for the installation of (ceramic tile or stone). Over a framing system and subfloor panels built to applicable code requirements (con sidering the intended live and dead load) a system detailed in the TCNA Handbook For Ceramic, Glass, and Stone Tile Installation (TCNA Handbook) and recommended by all relevant manufacturers for this application must be installed. Systems in the TCNA Handbook are tested using ASTM C627 criteria which includes concentrated loads and are therefore subject to a more stringent requirement than flooring soft goods. All tile floor assemblies must comply with the corresponding applicable de tails as outlined in the TCNA Handbook , to ensure the tile installation will function properly. When installing stone tile, consult with the The Natural Stone Institute (NSI) for recommendations on defection. It is the responsibility of the building owner to communicate in writing to the proj ect design professional and general contractor the intended use of the tile instal lation, in order to enable the project design professional and general contractor to make necessary allowances for the expected live load, concentrated loads, impact loads, and dead loads including the weight of the tile and setting bed.

If you have any questions, please do not hesitate to contact me.
