INSPECTION

A.

Examine areas to receive the work for defects which will affect the execution of the work and for deviations beyond allowable tolerances.

B.

Start work when defects have been corrected.

3.2

SURFACE PREPARATION

A.

Protect adjacent surfaces from staining or damage caused by installation.
