STEEL SHEET PILING

A. Templates

1. All steel sheet piles shall be driven with templates which will ensure proper and exact location and plumbness of the steel sheet piles. They shall be suitable, heavy, adequately rigid, straight, and adapted to the length and the weight of the steel sheet piles to be driven.

2. The templates to be used for all sheet pile walls shall be as recommended by the steel sheet pile supplier.

3. Templates and driving details, including fabrication drawings, shall be submitted to the Contracting Officer for approval, prior to fabrication. The templates shall include rollers made of ocolan, or an equivalent low friction (friction coefficient against steel � 0. 2) material, to avoid damage to the pile coating. The Contractor shall be responsible for the accurate location and securing of the templates in their correct positions before driving steel sheet piles.

7. Apply coatings at a temperature recommended by manufacturer.

8. Discard all catalyzed coatings at the end of each working day or at the end of manufacturer's recommended pot life, whichever is first.

9. After each coat and immediately prior to application of a subsequent coat, clean surface as required to remove dirt, dust, over-spray, and other contaminants that may affect adhesion of the subsequent coat.

B. Finish coat shall be uniform in color and gloss over the entire surface. Finish coat shall be smooth to touch with no sags, runs, over-spray, cracks, pinholes, drips or any other surface defects.

C. Coating Repairs

1. Touch-up or refinish all chipped, abraded, or otherwise unsatisfactory portions of the work in accordance with the manufacturer's recommendations.

2. Re-coating or touch-up or areas that have cured beyond the maximum time recommended by the manufacturer require special preparation, including amine testing.

3. Coating shall be applied free of runs, dry spray, drips, fish eyes, etc.

INSPECTION

A NACE Level III Certified Coatings Inspector, provided by the Contractor, shall be onsite during all phases of shop coating operations and field coating touchup operations, from surface preparation to final clean-up. Visual inspection for pinholes, holidays, dry spray, sags and other flaws shall be performed after each coat is applied.

All such flaws shall be corrected to the satisfaction of the inspector before the next coat is applied.

Inspector will evaluate cleanliness of coated surface immediately prior to application of a subsequent coat.

The final film is to be visually inspected and should be free of sags, runs, wrinkles and other excessive film build characteristics and surface defects.

APPLICATION QUALITY CONTROL

The right is reserved by Contracting Officer to invoke the following material testing procedure at any time, and any number of times during period of Shop and Filed painting:

1. Engage services of an independent testing laboratory to sample paint being used.

2. Samples of materials delivered to project site will be taken, identified and sealed, and certified in presence of NACE Inspector.

3. Testing laboratory will perform appropriate tests for any or all of following characteristics:

Abrasion resistance, apparent reflectivity, flexibility, wash ability, absorption, accelerated weathering, dry opacity, accelerated yellowness, recoating, skinning, color retention, alkali resistance and quantitative materials analysis.

4. If test results show that material being used does not comply with specified requirements, Contractor may be directed to stop painting work, and remove noncompliant paint; pay for testing; repaint surfaces coated with rejected paint; remove rejected paint from previously painted surfaces if, upon repainting with specified paint, the two (2) coatings are non compatible.

5. If requested, it will be the responsibility of the Contractor to arrange for additional inspections.

6. All parts of the work area shall be made accessible, through proper rigging, so that the independent inspector can record.

7. DFT measurements shall be taken after application of paint systems by the independent inspector using a typical apparatus such as a Mikrotest single prong gage.

B. The Contracting Officer may require, in addition to or as a substitute for the test apparatus described above, testing by the low voltage, wet sponge method.

C. All thickness readings shall be taken per SSPC PA-2.

D. Any deficiencies in the continuity of the coating shall be corrected by applying additional finish coats, at the expense of the Contractor.

E. The Contractor or representative of the paint manufacturer shall furnish the necessary test equipment and perform all tests in the presence of the Contracting Officer.

3.8 CLEANUP AND PROTECTION

A. During the course of the work, remove from site discarded paint materials, rubbish, cans and rags at the end of each work day.
