Floor Flatness / Levelness

Floor Flatness / Levelness

Floor Flatness / Levelness

(OP)


Who is responsible for setting the criteria and including the criteria in the specifications/documents? The architect or the engineer or both?

RE: Floor Flatness / Levelness

If the project is being run by an Architect, I would suggest that it was their responsibility since they should know what the needs of the owner/equipment are and are experts in overall building design. If the project is run by an Engineer, with little or no Architectural involvement, then this should be established by the Engineer.

RE: Floor Flatness / Levelness

I agree with dik. However, I have also had some clients that will specify. If a large client may want to confirm if they have general and/or project specifications.

RE: Floor Flatness / Levelness

Generally discuss this with the Client and stipulate this in my General Notes:
