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 flume at proper elevation in accordance with drawings.
D. Set floor of flume at inlet end level with flow and across flow. Set side walls plumb. Set top flanges level, each side.
E. Fasten flume securely to prevent flotation or twisting during placement of concrete.
F. Place concrete along sides and bottom of flume to ensure complete filling without voids and displacement of flume. Stage placement in alternating lifts, 1/3 height on each side of flume.
