SOLICITATION FOR THE JOHN DAY LOCK & DAM POWERHOUSE SUBMERGED TRAVELING SCREEN (STS), NEW 130 TON GANTRY CRANE – SOLICITATION W9127N20R0005 The U.S. Army Corps of Engineers, Portland District has a new requirement for a New 130 Ton, Submerged Traveling Screen (STS) Gantry Crane, at the John Day Lock and Dam, near Rufus, OR. This work consists of replacing the existing John Day Dam Powerhouse Submerged Traveling Screen (STS) 90 Ton Gantry Crane located at the John Day Lock and Dam, north of Rufus, Oregon. This project will consist of designing, manufacturing, factory testing, transporting, erecting, and field testing a new 130 ton, outdoor gantry crane comprising of a main hoist, an auxiliary hoist, and a latching hoist. The crane system will have built-in capabilities to meet a range of operating conditions, and modes that include: variable speed control; interlocking operating mode controls to eliminate operating hazards, reduce safety risks, and prevent use of systems that could result in equipment damage. The crane will need to be able to adapt to lifting different loads and load types under changing outdoor environmental conditions (such as high winds and variable weather conditions), and the ability to manage and handle loads underwater over a wide elevation range. In addition to the new crane work, the contractor will deconstruct/disassemble the existing 90 Ton STS Crane and safely remove it, in compliance with all environmental requirements. Known Constraints: 1. At no time during the project shall the powerhouse be without an operational STS gantry crane. The Corps of Engineers will ensure operability of the existing 90 Ton STS gantry crane. 2. The new STS Crane must be assembled at the south end of the rails so that the existing gantry crane can be used by the Government to access all of the main units during the assembly of the new crane. The construction area of the new 130 Ton STS Crane cannot impede the existing STS Crane operations. Based on how the old and new cranes are oriented, once the demolition starts on the existing crane, the new STS Crane will be unavailable for use (due to its location between the end of the runway and the existing crane), that it cannot travel. 3. Demolition of the existing crane will also be at the approved end of the rails as located on the contract drawing(s). The busiest season for trash raking is between 15 March and 15 June. Dependent on approved schedules, the new STS gantry crane should be completed and ready for service no later than 15 April 2022. The existing crane demolition is anticipated to be between 1 August 2022 and 31 August 2022. Both the existing and new STS gantry cranes will be on the same rail at the same time, located at the south end. 4. During construction and demolition phases of the work, road access across the top deck of the dam must be maintained. a. Road closure requests must be coordinated with the COR and Operations. b. For longer term road closures, through access may be limited to the start, middle, and end of the work day. c. At the end of the Contractor's work day the road access must be passable. 5. This solicitation will use a FAR Part 15.101-1 Best Value Tradeoff Process. This is a hybrid supply with construction installation contract. Acquisition will provide for Full and Open Competition. 18 August 2020 Due to numerous requests, additional STS Crane drawings have been uploaded for reference.
