City of Santa Ana <br />Coating, Painting and Structural Inspection Proposal <br />March 15, 2004 <br />compliance with specifications. <br />(1) Preliminary Cleaning - <br />(a) Surface will be inspected to verify removal of grease, oil, <br />chemicals etc. after completion of solvent cleaning of <br />surface. <br />(2) Abrasive Blast Cleaning - <br />(a) Surfaces will be observed throughout blast cleaning <br />operations to determine compliance with specification. <br />Physical tests for surface profile will be performed using <br />a K-T Surface Profile Comparator. At completion of <br />blast cleaning, areas not meeting specification will be <br />reblasted and tests again performed. This cycle will be <br />repeated until surfaces are accepted for coating <br />application. <br />(b) Upon completion of above inspection, dust and other <br />surface contaminants will be removed as specified and <br />surfaces visually and physically inspected for compliance <br />to specification. <br />6. PRIME COAT INSPECTION (EXTERIOR) -After approval of surface <br />preparation, ongoing inspection monitors weather condition, Contractor's <br />application equipment and its operation, mixing of primer and physical <br />inspection of prime coat application, including spray techniques, cleanliness of <br />surface, thickness, etc. <br />a. Weather conditions will be verified by use of an electronic or sling <br />psychrometer to determine suitability of climatic conditions prior to and <br />during all application operations. <br />b. Contractor's equipment is constantly monitored to determine operation <br />will not contribute to any degradation of application (oil, moisture, etc.) <br />c. Paint materials are inspected for compliance to specification and all <br />mixing/thinning operations are monitored. <br />d. Surfaces are re-inspected to verify no dust or other contaminants are on <br />surface and remedial cleaning performed as required. <br />e. After approval of surface, application is carefully monitored to verify <br />Harper & Associates Engineering, Inc. <br />proposals~INSP-Santa Ana 10 <br />
