No standard tolerance exists for slopes in random-traffic floors and other slab surfaces. But the author -- president of a consulting engineering firm that assists in the planning and construction of slabs on grade and suspended concrete floors -- feels that one is needed. He has developed a proposed specification for sloped random-traffic floors and would like suggestions for improving it.

The specification includes surface-tolerance requirements, procedures for taking tolerance measurements, testing requirements and remedies for out-of-tolerance work.
