MATERIALS A. Comply with requirements specified in other Sections. B. In-Place Materials: Use materials for patching identical to in-place materials. For exposed surfaces, use materials that visually match in-place adjacent surfaces to the fullest extent possible. 1. If identical materials are unavailable or cannot be used, use materials that, when installed, will provide a match acceptable to Architect for the visual and functional performance of in-place materials. Use materials that are not considered hazardous. C. Cleaning Agents: Use cleaning materials and agents recommended by manufacturer or fabricator of the surface to be cleaned. Do not use cleaning agents that are potentially hazardous to health or property or that might damage finished surfaces. PART 3 - EXECUTION 3.1 EXAMINATION A. Existing Conditions: The existence and location of underground, concealed, and other utilities and construction indicated as existing are not guaranteed. Before beginning Work, investigate and verify the existence and location of underground and concealed utilities, mechanical and electrical systems, and other construction affecting the Work. 1. Before construction, verify the location and invert elevation at points of connection of sanitary sewer, storm sewer, gas service piping, and water-service piping; underground electrical services; and other utilities. B. Examination and Acceptance of Conditions: Before proceeding with each component of the Work, examine substrates, areas, and conditions, with Installer or Applicator present where indicated, for compliance with requirements for installation tolerances and other conditions affecting performance. Record observations. 1. Examine roughing-in for mechanical and electrical systems to verify actual locations of connections before equipment and fixture installation. 2. Examine walls, floors, and roofs for suitable conditions where products and systems are to be installed. 3. Verify compatibility with and suitability of substrates, including compatibility with existing finishes or primers. C. Written Report: Where a written report listing conditions detrimental to performance of the Work is required by other Sections, include the following: 1. Description of the Work, including Specification Section number and paragraph, and Drawing sheet number and detail, where applicable. 2. List of detrimental conditions, including substrates. 3. List of unacceptable installation tolerances. 4. Recommended corrections. D. Proceed with installation only after unsatisfactory conditions have been corrected. Proceeding with the Work indicates acceptance of surfaces and conditions.
