Gavins Point Crane Rail Replacement

2026. This project will involve removal and replacement of the Gavins Point Powerhouse Intake crane runway rail located near Yankton, South Dakota. The 80-ton Gavins Point Intake Gantry Crane rail shall be installed and aligned to Crane Manufacturers Association of America, CMAA 70 standards. The total length of the rails is 328 ft x 2 centerline of rail to the powerhouse wall. The work will include an initial survey of the rail alignment, existing grout pocket condition, demolition and removal of existing intake crane rail and components, rail clips, asphalt, base plates, and non-shrink grout. Demolition and removal of the existing concrete anchors will be based on the concrete imaging reports, and the grout pocket condition assessment between each anchor pair along the deck. For bidding purposes, it is assumed 80 percent of the existing anchors will be replaced and all concrete anchors at joint bars will be replaced. The contractor will provide anchors suitable for use in cracked concrete and under seismic loading. Once the rail and hardware are replaced and aligned to the required standards the grout pockets will be filled with two-component aliphatic polyurethane elastomer grout along the full length of the intake crane runway as shown on the drawings. The sequencing of demolition and installation of the crane rails must minimize project time without an operational intake crane and typically progress from one side of the dam to the other with the transfer of the crane from old to new rail during completion of the final rail segment. The Contractor will be required to commence work upon receipt of contract award and complete the work 365 calendar days after receipt of Notice to Proceed, this is subject to change after solicitation issuance.
