Robert S Kerr Powerhouse Turbine/Generator Rehabilitation

This is a PRE-SOLICITATION NOTICE for the construction project consisting of the rehabilitation of the R.S. Kerr Turbine Generating Units 1 through 4 at the R.S. Kerr Powerhouse in Oklahoma. THIS IS NOT A SOLICITATION FOR PROPOSALS AND NO CONTRACT WILL BE AWARDED FROM THIS SYNOPSIS.  No reimbursement will be made for any costs associated with providing information in response to this pre-solicitation notice or any follow up postings.

The U.S. Army Corps of Engineers – Tulsa District has been tasked to solicit for and award a contract to rehabilitate the Turbine Generating Units 1 through 4 at the R.S. Kerr Powerhouse in Oklahoma. The proposed project will be a competitive, firm-fixed priced contract procured in accordance with FAR 15, Negotiated Procurement using the trade-off process.

Project Description:

This will be a total turn-key contract with all work being performed by the contractor unless explicitly stated otherwise in the specifications. The requirements of this project are to provide all equipment, labor, materials, and work required to refurbish Robert S. Kerr turbine generating Units 1 through 4 at the Robert S Kerr Powerhouse located in Sallisaw, Sequoyah County, Oklahoma. The existing turbines are five-bladed Kaplan-type units manufactured by Allis Chalmers. They were designed for a maximum output of 46,000 hp but have been operated at 35,000 hp to accommodate the existing generator nameplate of 28,947 KVA at a power factor of 0.95. The units have been generator limited over their life. The rehabilitation of each turbine generator unit shall include the rehabilitation of the existing runner and the rewind of its corresponding generator. This work will require the disassembly of the runner hub and replacement and refurbishment of internal components, rewind of the generator, and replacement or rehabilitation of other components as required in the specifications. The contractor shall also be required to rehabilitate Units 1 through 4 by replacement of the generator stator winding. The new stator winding shall be rated at 42,000 KVA at a power factor of 0.9 with a temperature rise limited to 75 degrees C above a 40 degree C ambient temperature. Replacements of Units 1 through 4 generator stator cores will be included as an option to be exercised on an as needed basis. The field winding will be inspected, tested, and cleaned. Specifically, the proposed plan of work involves the contractor furnishing all supervision, engineering, labor, materials, and equipment to perform the following work in strict accordance with the detailed requirements of the contract.  

In accordance with FAR 36.204 and DFARS 236.204, Disclosure of the Magnitude of Construction Projects, the estimated magnitude of construction for this project is between $100,000,000 and $250,000,000.

The North American Industry Classification System code for this procurement is 237990, which has a small business size standard of $39.5M. It will be solicited as an unrestricted procurement.  

The estimated duration of the construction phase of this project is 2,710 calendar days.

The anticipated solicitation issuance date is on or about 22 June 2020, and the estimated proposal due date will be on or about 3 September 2020.
