- 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.
