PART 3

EXECUTION

3.1

EXAMINATION

Examine structural members before beginning installation to ensure that all supporting members are straight, level, plumb and satisfactory for panel installation.

Verify roof openings, curbs, pipes, sleeves, ducts, or vents through roof are solidly set, reglets are in place, and nailing strips located.

Correct defective conditions before beginning work.

3.2

INSTALLATION

Install in accordance with manufacturer's instructions and recommendations including approved shop drawings, installation guidebook and manufacturer's handbook of construction details.

Form panel shape as indicated on Drawings, accurate in size, square, and free from distortion or defects.

Install flashing and trim true and in proper alignment.

Install sealants where indicated to clean dry surfaces only without skips or voids, to ensure weather tightness and integrity of the vapor barrier.

3.3

CLEANING

Replace damaged panels and other components of work, which cannot be repaired by finish touch-up or similar minor repair.

Wipe finished surfaces clean of any filings caused by drilling or cutting to prevent rust staining.

3.4

PROTECTION

Protect installed products until completion of project.

Touch-up, repair or replace damaged products before Substantial Completion.
