PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until the substrates have been properly constructed and prepared.
1.	Verify surfaces and site conditions are ready to receive work. 
a.	Correct defects in the substrate before commencing with roofing work. 
b.	Verify roof openings and penetrations are in place, curbs are set and braced, and roof-drain bodies are securely clamped in place.
B.	If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.
1.	Obtain relevant instructions and maintain copies at project site for duration of installation period.
2.	Verify shop drawings prepared by metal roof panel manufacturer have been approved and are available to installers.
a.	Do not use drawings prepared by others for installation drawings.
3.	Verify the specifications and drawing details are workable and not in conflict with the roofing manufacturer's recommendations and instructions.
a.	Start of work constitutes acceptable of project conditions and requirements.
4.	Examine roof substrate to verify it properly slopes to drains.
5.	Confirm roof deck will support installers and their mechanical equipment, and that the deflection will not strain or rupture roof components or deform deck.
6.	Verify wood blocking, curbs, and nailers are securely anchored to roof deck at penetrations and terminations and that nailers match thicknesses of insulation.
C.	A certain amount of waviness called 'oil canning' is inherent in any product manufactured from coiled sheet material. The amount of 'oil canning' can vary due to several factors: uneven substrates, the width of the panel, weather conditions, etc. 'Oil canning' of a panel does not affect its structural integrity and is not sufficient cause for rejection.
3.2	PREPARATION
A.	Clean surfaces thoroughly prior to installation.
B.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
1.	Prepare roof surface so that it is clean, dry, and smooth, and free of sharp edges, fins, roughened surfaces, loose or foreign materials, oil, grease, and other materials that may damage the panels.
