Submit manufacturer-specific installation instructions for SIP system.

Warranty: Provide limited warranty documents as specified herein.

QUALITY ASSURANCE

Installer Qualifications: Installer to have demonstrated experience acceptable to SIP Manufacturer for installation work similar in scope and size to this project. Manufacturer to confirm availability of site advisory service.

Field Measurements: Request field measurements prior to completion of shop drawings and fabrication. Coordinate fabrication schedule with construction progress to avoid delay of work. NOTE: Field fabrication is allowed to ensure proper fit after consultation with manufacturer, but must be kept to minimum with majority of SIP fabrication being done under controlled shop conditions.

Source limitations: Obtain all SIPs through one source. All accessories to be furnished or recommended by the SIP manufacturer.

REGULATORY REQUIREMENTS:

SIPs shall be recognized for compliance with the applicable building code with an ICC-ES evaluation report demonstrating compliance with the International Building Code (IBC).

DELIVERY, STORAGE AND HANDLING

Ordering: Comply with SIP manufacturer ordering instructions and lead time requirements to avoid construction delays.

Delivery: Deliver materials from SIP manufacturer with identification labels or markings intact.

Unloading: Off-load SIPs from delivery truck and handle using fork lift, crane or other means to prevent damage to SIPs.

Storage: SIPs shall be fully supported in level storage and prevented from contact with the ground. Stack SIPs with a minimum of three supports for every eight feet of SIP length.

Protection: SIPs shall be fully protected from the weather. Protect against exposure to rain, water, dirt, mud, and other residue that may affect SIP performance. Cover stored SIPs with breathable protective wraps. Sips shall be stored in a protected area.

WARRANTY

SIP Manufacturer Warranty: Submit SIP manufacturer standard warranty document for execution by an authorized company official for a period of 20 years after the completion of the project.
