2.03 Manufacturers/Contractors
A. All components called for in this section to be supplied by the panel manufacturer shall be obtained from the selected manufacturer.
Part 3 – Installation
3.01 General
A. The contractor shall inspect conditions of substrate, grade and other conditions, which may affect the proper installation of panels. Any adverse conditions are to be reported in writing to the construction manager. Do not proceed with the installation until adverse conditions are corrected.
B. Installation shall be in strict accordance with manufacturer’s published instructions, details, and the drawings that are part of the contract documents for this project. Any conflicts between these documents shall be resolved in writing. All plans shall be reviewed by a registered professional engineer and shall be signed and sealed. Deviations from standard detail and load design values shall be calculated and signed and sealed by a registered professional engineer.
3.02 Protection
A. When storing panels, do not allow them to come into contact with the ground. Stored panels must remain dry and in the manufacturer’s original packaging. Do not allow panels to be stored in an unsupported manner. Improper storage may cause tolerance problems in the field.
B. Roof panels must be fully protected from weather by roofing materials or other means to provide temporary protection at the end of the day, or when rain or snow is imminent.
C. Remove and replace insulated wall or roof panels which have become excessively wet or damaged before proceeding with installation of additional panels or other work.
