B. Support/Attachment Devices

1. Spring steel shield clips of the size recommended by manufacturer, for securement of the cover. Clips shall be produced from 21 Gauge minimum zinc-plated spring steel and shall have a reverse curvature design such that the clips soundly secure the soffit from easy removal. Each clip shall be demonstrated as being able to resist a force of 100 lbs. uplift at the free end. Test results shall be available upon request.

C. Soffit/Cover

1. The soffit/cover shall be smooth in appearance and shall be made of 24 Gauge G90 zinc galvanized steel with a paintgrip finish*, or in accordance with the material specifications as shown below. The cover shall have a snap-lock interfacing with the clips such that once assembled, it is rendered virtually irremovable with the use of ordinary tools.

2. The soffit and related fittings shall be factory painted with Sherwin Williams epoxy polyester hybrid powder coating of a color to be specified by the owner’s representative. Matching touch-up paint shall be supplied to the owner by the manufacturer.

3. Cover manufacturer shall be staffed with a licensed engineer having a minimum of five years experience with such systems.

4. The cover shall be sized in accordance with requirements to accommodate the specific application size as specified by the project documents, specifications and blue prints, provided to the cover manufacturer prior to bid date.

5. L-Design shield cover for sidewall installations and/or U-Design shield cover for sidewall and/or pendant installations respectively.

6. Cover joints shall be butt-joined with interlocking internal splice couplings and/or with male/female interlocking joints. External couplings will NOT be allowed.

7. Cover design shall include a rollformed "groove" at the interfacing of the cover and the adjacent construction surface to facilitate the application of sealant/adhesive compounds and enhance the security of such compounds from dislodging.

*NOTE TO SPECIFIERS: Other options are available.

* Stainless steel with #4 finish: 18 Gauge, 20 Gauge, 22 Gauge, and 24 Gauge

* Cold-Rolled Steel: 18 Gauge, 20 Gauge, 22 Gauge, and 24 Gauge

Finishes available with cold-rolled steel:

* Zinc-galvanized Paintgrip (treated to accept painting but not painted) of ASTM-A527 Coating Class G90.

* Zinc-galvanized Paintgrip, factory treated and factory painted in colors selected by architect from manufacturers standard colors. Custom colors available upon request.

* Primed with specific primer, which will be compatible with paint scheduled after installation.

D. Accessories

1. The system shall include tamper-resistant end caps, prefabricated corners, wall flanges, couplings, and other items which may be necessary to complete the system, and shall be installed in accordance with the manufacturer's recommendations.

2. Spare Parts - The installing contractor shall supply the owner with quantities of spare parts equal to a minimum of five percent (5%) of the total quantities of each Soffi-Steel® System part utilized in this installation.

PART 3 EXECUTION

3.01 INSTALLATION

A. Installation of system shall be in strict accordance with approved shop drawings and manufacturer's printed instructions.

1. If used to conceal fire sprinkler systems, the sprinkler contractor/engineer must determine the piping and sprinkler layout, including sprinkler head locations and pipe support locations (based on pipe manufacturer's specs.). Indicate areas on drawings where cover system is to be used.

2. Select appropriate fasteners for the substrate encountered to adequately secure the pipe and cover system.

3. To insure that the cover is linear and snug-fitting when installed, it is imperative that its support devices are anchored squarely and firmly in a straight line against the structural surface.

4. All penetrations to the soffit/cover system shall be field cut to prevent misalignment with intended protrusion. The exceptions to this are that access doors may be factory furnished and installed and perforations, if required for ventilation, may be factory perforated.

5. Guidelines for installation of modular soffit/cover system shall be supplied by the manufacturer of said system and the installing contractor shall adhere to the manufacturer's guidelines. Such guidelines shall be supplied by manufacturer in the form of written installation instructions.

6. Manufacturer shall, upon installer's request, supply on-site installation instruction by a qualified installation instructor for a minimum of one day for the project start-up (1,500 lineal feet minimum.)

7. All field ends and scratches shall be ‘touched up’ (spray or brush) with a matching paint.

8. The completed installation shall be visibly searched for voids between the interfacing of the cover and construction surface. Voids shall be sealed with a color matching urethane caulk.
