,.., . II . OP 1, OP 2 and OP 3, as appropriate to the Method of Coating Application, prior to Contract award. Provide documentation to the Engineer that all personnel performing coating inspections are NACE CIP certified or are reporting directly to a NACE CIP certified inspector. Certification must be maintained for the duration of the Contract. If certification expires, the firm will not be allowed to perform any work until the certification is reissued. Requests for extension of time for any delay to the completion of the project due to an inactive certification will not be considered and liquidated damages will apply. Notify the Engineer of any change in Contractor certification status. ,.., . II . ,.., . -. 560-7 Surface Preparation. 560-7.1 Surface Cleaning: Ensure all surfaces to be coated are clean, dry, and free from oil, grease, dirt, dust, soluble salts, corrosion, peeling coating, caulking, weld spatter, mill scale and any other surface contaminants. Prepare all surfaces that will become inaccessible after fabrication, erection, or installation while accessible. Sequence the surface preparations and coating operations so that freshly applied coatings will not be contaminated by dust or foreign matter. Protect all equipment and adjacent surfaces not to be coated from surface preparation operations. Protect working mechanisms against intrusion of abrasive. In the event that any rusting or contamination occurs after the completion of the surface preparation, clean the surfaces again to the initial requirements. All corners resulting from sawing, burning, or shearing operations must be broken. Clean all welds and prepare the area within 2 inches [50 mm] of welds by blast cleaning, power wire brushing, water scrubbing, or chemically scrubbing to remove all detrimental welding deposits and to create a surface profile meeting the coating manufacture requirements. 560-7.1.1 Degreasing: Degrease by solvent cleaning, detergent washing, or steam cleaning in accordance with SSPC-SP 1. 560-7.1.2 Water Washing: When high levels of chloride or other undesirable contaminants are found on the surfaces, water wash using standard industrial pressure cleaners with a pressure versus volume output balance that will ensure thorough cleaning. 560-7.1.3 Soluble Salts Detection and Removal: Determine the chloride, sulfate and nitrate concentrations on all structure surfaces, using soluble salts test kits meeting the requirements of 560-2.4, laboratory test methods or other method approved by the Engineer capable of accurately detecting the concentrations at required limits. Measure the chloride level using a method described in SSPC-TU 4. Ensure the chloride level on the blast-cleaned surface does not exceed 7 /-lg/cm2 in accordance with SSPC-SP 12, NV-2. Assessing Conformance with Blast Cleaning Standards. After surface preparation on structural steel, thoroughly inspect the surfaces. Take soluble salt measurements at the test rate identified in SSPC-PA2. When the test results exceeds 7 !-lg/cm2 for any of the salt concentrations, the inspector will increase the rate of measurements as required to determine the extent of the deficient area. If water washing does not reduce the soluble salt concentration to the acceptable levels, a surface treatment or water additive may be used. Ensure the surface treatment or additive is approved by the Coating System supplier and the Engineer. II . ..., . .., . , . .., . .., I . II . M . . -. . II .
