PART 3 EXECUTION
3.1 EXAMINATION
A. Verify that dimensions are correct and project conditions are suitable for installation. Do not proceed with installation until unsatisfactory conditions have been corrected.
3.2 INSTALLATION
A. Install products in accordance with manufacturer's instructions.
B. Ensure that products are installed plumb and true, free of warp or twist, within tolerances specified by the manufacturer and as indicated in the contract documents.
C. Set flumes at proper elevation as indicated on drawings.
D. Install flumes in true level position, both laterally and with the stream.
NOTE ** Flumes may be held in place by adhesive (such as RTV), grouting, or sand bags.
E. Embed flumes in concrete; place concrete in stages or internally brace flume walls to eliminate possibility of bowing and to ensure complete contact without voids. Temporarily secure flumes until concrete has hardened.
3.3 ADJUST AND CLEAN
A. Clean surfaces in accordance with manufacturer's instructions.
B. Remove trash and debris, and leave the site in a clean condition.
