No Yes

4.0 Installation

4.1 Tolerance Requirements. No panels shall be erected if the structural steel does not meet the tolerances of the A.I.S.C. Code, Section 7. It is the responsibility of the contractor to examine this alignment before the panels are erected. The Contractor is responsible for properly installing the roof system and ensuring that all purlins or sub-framing members are properly installed.

4.2 Side Laps. Side laps must be fully seamed, either by hand seaming or with an electric seaming machine, to ensure the integrity of the total roof system.

4.3 Accordances. The panels shall be installed in accordance with the drawings or standard details and instructions furnished by the manufacturer.

4.4 Appearance. Due to the inherent tolerances of base , any flat surface panels could have some "oil canning". This will not be a basis for panel rejection.
