Project Scope:
Knight Const. & Supply, Inc. (KCS) was responsible for design, fabrication and installation of two new 21’ tall and 33’ wide tainter gates and all gate appurtenances including the gate control system and hoist system. KCS designed to the current hydraulic structures criteria to meet seal performance criteria, with attention to constructability, ease of use, ease of maintenance and avoidance of corrosion pockets.
