Part 1 – GENERAL

1. SCOPE OF WORK

A. The work covered by this specification consists of installing 18 oz. per square yard PVC coated polyester, in the areas shown on the project drawings. All work shall be in strict accordance with the project drawings, these specifications and the Fabricator’s approved shop drawings. All work is subject to the terms and conditions of the contract.

B. Sufficient material shall be furnished to cover all areas as shown on the drawings.

2. MANUFACTURER, FABRICATOR, INSTALLER INFORMATION

A. The following shall be the minimum information submitted at the time of the bid, relating to the PVC Coated Polyester Curtain Manufacturer, proposed Fabricator and Installer: Name, Address, Phone, FAX (Note: Failure to submit this information at the time of bid may disqualify the proposal).

B. Acceptable manufacturers for the PVC Coated Polyester Curtains include the following:

AKON, LLC Fernandina Beach, FL 32034; Amcraft Manufacturing, Inc. Elk Grove Village IL 60007; Steel Guard Safety Products, South Holland Illinois 60473; Goff’s Enterprises Pewaukee, WI 53072; Chase Doors Cincinnati, OH 45246; additional manufacturers may be approved if products meet the specifications.

3. PRODUCTS

A. The PVC coated polyester material shall be 18 oz. per square yard and capable of outdoor use. The membrane shall be manufactured by the calendering process, consisting of first quality ingredients, suitably compounded, of which polyester is the principal resin. The finished compound shall be uniform in color, thickness, size and surface texture.

B. The finished membrane shall consist of two (2) plies of PVC plastisol laminated over one (1) ply of polyester reinforcing scrim.

C. The PVC coating shall fully encapsulate the scrim and shall extend a minimum of 1/8-in.

(3.175 mm) beyond the reinforcing scrim roll edges. Exposed fabric along the longitudinal edges of the roll stock shall not be permitted.

4. SUBMITTALS

A. The Polyester Coated curtain shall be factory fabricated into rolls 100 yards in length and 61 inches in width. The Fabricator shall furnish a proposed curtain panel layout that is to be approved in writing by the Engineer prior to the installation. The drawings shall show the extent, the direction of factory seams and the size of panels, consistent with the requirements of the project drawings. Maximum use of large size panels shall be made to minimize field seaming.

13080-2 T:\208 Marion County\88_Oak Run WWTP Buffer\Docs\Curtains\13080 PVC Coated Polyester Curtains.doc

5. FACTORY FABRICATION

A. The Fabricator shall be an experienced firm customarily engaged in factory-fabricating individual curtains using roll stock into custom panels.

B. Polyester coating of curtains shall be thermal sealed and inspected to have uniform color throughout, except in areas identified on the drawings for the transparent clear window material.

C. Prior to factory seaming, all roll goods shall be inspected. All factory seams shall be made by thermal fusion methods. All factory seams shall have a minimum scrim-to-scrim overlap of one and one half inches (1½-in.) (3.81 cm) when fabricated. Fabricated seams found to have less than the specified minimum overlap shall be repaired by adding an overlap or cap strip that provides the minimum specified overlap or will be rejected. All seams shall be made so that the thermal fusion bond extends fully to the top edge of the sheet so that no loose edges are present on the topside of the sheet.

D. Support brackets shall be grade 304 stainless steel. Brackets shall be 5 feet in length to ensure stability to the hanging polyester coated curtains with a 2:1 factor of safety in regards to load vs distance. Testing for strength of 304 stainless steel should comply with ASTM A240.

6. INSPECTION AND TESTING

A. Inspection

i. All curtains and seams shall be 100% visually inspected during fabrication. No defective seams will be allowed. All indicated design parameters shall be followed and made by the Fabricator before the panels are packaged for shipment.

B. Testing

i. In addition to visual inspection, a 48-in. (1.2 m) sample shall be taken from each factory seam welding unit used in this work at the beginning of every work shift and every four hours of production thereafter. Samples shall be non-destructive, i.e., will not require patching of fabricated panels. Test specimens shall be cut at quarter points from each 48-in. (1.2 m) seam sample (a total of three places) and tested for factory seam strength and peel adhesion.

ii. The shear seam strength shall be tested in accordance with ASTM D2261. The strength of the Polyester coating adhesion shall be tested in accordance with ASTM D2724.

Tensile strength standards shall be in accordance with ASTM D2261.

iii. A log shall be maintained showing the date, time, panel number and test results. Failure of the material and/or seams to meet all the requirements of these specifications may be cause for rejection of the Polyester material and/or seams as appropriate. The Fabricator shall provide the test results to the Owner or Engineer upon request.

13080-3 T:\208 Marion County\88_Oak Run WWTP Buffer\Docs\Curtains\13080 PVC Coated Polyester Curtains.doc

8. PACKAGING AND STORAGE

A. Each factory-fabricated panel shall be rolled and/or accordion-folded and placed onto a sturdy wooden pallet designed to be moved by a forklift or similar equipment.

Until needed, packaged factory-fabricated panels shall be stored in their original unopened crates in a dry area off the ground, and protected from the direct heat of the sun, under an opaque, light colored heat reflective cover in a manner that provides a free-flowing air space between the packaged panel and the covering. Pallets should not be stacked.

B. Steel track shall be delivered in sections of 5 feet maximum to ensure that they are able to fit on a standard pallet size.
