1.6       PROJECT CONDITIONS

  1. Field Measurements:  Verify actual supporting and adjoining construction by field measurements before fabrication; and indicate recorded measurements on final Shop Drawings.  Coordinate construction to ensure that sun control assemblies fit properly to supporting and adjoining construction and coordinate schedule with construction progress to avoid delaying the work.
  2. Established Dimensions:  Where field measurements cannot be made without delaying the work, verify dimensions and proceed with fabricating of sun control assemblies without field measurements.  Coordinate construction to ensure that sun control assemblies             correspond to established dimensions.

A.   Locate and place sun control assemblies level, plumb, and at indicated alignment with adjacent work.

B.   Use concealed anchorages where possible.  Provide stainless steel/neoprene washers fitted to screws where required to protect metal surfaces and to make a weather tight connection.

C. Form closely fitted joints with exposed connections accurately located and secured.

D.  Repair finishes damaged by cutting, welding, soldering, and grinding.  Restore finishes so no evidence remains of corrective work.  Return items that cannot be refinished in the field to the factory, make required alterations, and refinish entire unit or provide new units.

E. Keep aluminum surfaces from direct contact with ferrous metal or other incompatible materials by applying one coat of clear acrylic coating.

3.3       CLEANING AND PROTECTING

Clean exposed surfaces of sun control devices that are not protected by temporary covering to remove fingerprints and soil during construction period.

B.   Clean exposed surfaces with water and a mild soap or detergent not harmful to finishes.  Thoroughly rinse surfaces and dry.

C.  Protect sun control assemblies from damage during construction.  Use temporary protective coverings where needed and approved by the sun control manufacturer.

D.  Clean and touch up minor abrasions in finishes with air-dried coating that matches color and gloss of, and is compatible with, factory-applied finish coating.

 

"I would like to take this opportunity to thank your construction crew for the fine job they did installing the new sidewalk and canopy on the east side of the Media Center building. They have been very cooperative with the rules on campus and cleaned their work area every day. Perfection Architectural Systems should be commended for the fine work they do, as well as scheduling and planning."
