City of Santa Ana <br />Coating, Painting and Structural Inspection Proposal <br />March 15, 2004 <br />1. Provide quality control inspection on an as-needed basis of the structural <br />modifications to be accomplished on each reservoir. <br />H. SCOPE OF WORK -COATING AND PAINTING <br />1. SURFACE PREPARATION INSPECTION (INTERIOR-SPOT REPAIR) - <br />Physical inspection of blast cleaned surfaces to verify compliance to <br />specification, removal of dust, etc. <br />a. Weather conditions will be verified by use of a electronic or manual <br />psychrometer to determine suitability of climatic conditions prior to and <br />during all blast cleaning operations. <br />b. Surface will be observed throughout cleaning operations to determine <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) Inspect blasted surfaces at the end of each day's shift to <br />determine compliance with specification. Physical tests <br />for surface profile will be performed using a K-T Surface <br />Profile Comparator. At completion of blast cleaning <br />each shift, 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 />2. PRIME COAT INSPECTION (INTERIOR-SPOT REPAIR) -After approval of <br />surface preparation, ongoing inspection monitors weather condition, <br />Contractor's application equipment and its operation, mixing of primer and <br />physical inspection of prime coat application, including spray techniques, <br />cleanliness of surface, thickness, etc. <br />Harper & Associates Engineering, Inc. <br />proposals~SantaAna-2tks 7 <br />
