G. Project conditions

1. Environmental limitations: do not deliver or install visual display units until spaces are enclosed and weather tight, wet-work in spaces is complete and dry, work above ceilings is complete, and temporary hvac system is operating and maintaining ambient temperature and humidity conditions at occupancy levels during the remainder of the construction period.

2. Field measurements: verify actual dimensions of construction contiguous with visual display units by field measurements before fabrication.

a. Allow for trimming and fitting where taking field measurements before fabrication might delay the work.

H. Warranty

1. Special Warranty for Porcelain-Enamel Face Sheets: Manufacturer agrees to repair or replace porcelain-enamel face sheets that fail in materials or workmanship within specified warranty period.

a. Failures include, but are not limited to, the following:

1) Surfaces lose original writing and erasing qualities.

2) Surfaces exhibit crazing, cracking, or flaking.

b. Warranty Period: Life of the building.

PART 2 - PRODUCTS
