PROTECTIVE COATINGS STANDARD SPECIFICATION ROADWORKS DoI REFERENCE TEXT December 2015 Page 135 22.27 Transition and Erection Damage and Field Weld Margins Spot abrasive blast all coating damaged during transit and erection, including field weld margins, such that it is thoroughly cleaned. Restore the area according to the coating manufacturer's recommendations with a material compatible with, and providing at least the same performance as, the parent coating. 22.28 Surfaces Not to be Coated Do not blast or coat the following surfaces and materials unless specifically directed by the Superintendent: - Stainless Steel - Other surfaces nominated by the Superintendent. 22.29 Surfaces Not to be Coated All work performed may be subject to inspection by the Superintendent or a nominated representative.

These must be approved prior to commencement of work. 22.32 Contractor Records Witness Point Maintain written records of the work so that complete traceability of all work and materials provided under this Specification is maintained. Use the relevant sections of AS 3894.10, AS 3894.11 & AS 3894.12 QA report forms as a basis of this record keeping format for all protective coating work under this contract. Use AS 3894.13 and AS 3894.14, in addition to the preceding Australian Standards, for structural steel work coated under this contract. Witness Point - Maintain these reports on a daily basis. Submit them to the Superintendent when requested, or, if not specifically requested, at least weekly.

Hold Point - Final acceptance of each increment of work will not be made until the dry film thickness meets or exceeds the specified thickness. Regardless of the number of coats specified, additional coats shall be applied as may be necessary to achieve the specified thickness, at the contractor's expense. Witness Point - Provide and operate wet film and dry film thickness gauges of approved types to ensure the correct thickness of each coat and the full system is achieved. Provide details of the gauges proposed for use. Use an electronic thickness gauge to determine the total dry film thickness on metallic substrates. Calibrate the gauges in accordance with AS 3894.3 (dry film thickness) or AS/NZ 1580.108.1 (wet film thickness). 22.34 Inspector Hold Point Appoint an inspector of coatings, qualified or certified under ACA, NACE, or ICorr, for inspection and testing of substrate preparation and protective coating systems applied under this contract.
