The client’s original Bascule gate was damaged and wedged against the abutment plates, preventing the gate from being operated. Based on an inspection of the gate, the client chose to replace it rather than repair it due to the extent of the damage. They replaced the gate with a Rodney Hunt Bascule gate system that included a new Bascule-type steel crest gate, torque tube, side seal plate assemblies, and plummer block mounting bracket supports. It was also decided to replace the cylinders in both abutments, upgrade the control system, and resurface areas of deteriorated concrete on the spillway and abutments.
Kleinschmidt developed a design and drawing package for the concrete modifications to the spillway and abutment structures to accommodate the new Bascule gate and address concrete deterioration around this section of the spillway. We provided mechanical component analysis and design for the connection of the Rodney Hunt-supplied components to the control equipment and the existing components. This included developing detailed fabrication-level drawings for the development of modifications to the existing components, a bill of materials, and torque values for the hardware. We also developed a trashrack air blast system design at the intake structure.
Our Team developed the construction bid package and provided bidding support. Kleinschmidt also visited Rodney Hunt’s manufacturing facility to review the gate components prior to shipment to the project site. Kleinschmidt provided engineering support during construction to address found conditions, modifications to the design, and integration of the various vendor components.
Kleinschmidt solved complex mechanical challenges associated with this project by coordinating the layout, definition, and interconnection of the Bascule gate mechanical systems to meet the client’s technical, budgetary, and schedule objectives. The client realized further efficiencies and cost savings by addressing the deteriorated concrete on the spillway and abutments and installing a new air blast system while resources were mobilized for the gate installation and associated concrete work.
