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

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.
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.
