Stennis Space Center (SSC) Navigation Lock. The SSC is a rocket engine testing facility operated by NASA in Hancock County, Mississippi, on the banks of the Pearl River at the Mississippi–Louisiana border. The SSC is located at the southwest corner of Mississippi about 50 miles northeast of New Orleans, Louisiana, and 30 miles from the Mississippi Gulf Coast. In general, the goal of this construction project is to rehabilitate both the upper and lower miter gates, allowing the SSC to maintain marine access to the NASA test facility into the future.  This Navigation Lock rehabilitation is needed to meet the long-term mission of NASA at the SSC. A miter gate consists of a left and right-hand leaf that are opposite hand but otherwise identical. The Contractor shall remove and lay flat each miter gate leaf on a deck barge for rehabilitation. Government-furnished lock chamber stop-logs may need to be installed at the upper end of the lock, depending on the Contractor’s work plan. The miter gate rehabilitation consists of blasting and painting the gates, replacement of all timber fenders, replacement of miter gate rubber seals, and structural member replacement and repair. Rehabilitation also includes cathodic protection system removal, repair, installation, and testing by corrosion expert in accordance with specifications. All four gate leaf operating hydraulic cylinders shall be removed and shipped to a capable facility for rehabilitation. Work to be completed prior to miter gate removal includes the fabrication of one set of replacement anchor bars and pins for use at the lower left miter gate anchorage, fabrication of special “turning feet” to facilitate miter gate laydown, fabrication and installation of miter gate lifting and laydown lugs, and temporary alterations of the miter gate walkway and bulkhead plate at the top of the gates.  During the period the gates are removed, the Contractor’s certified diver shall conduct inspections of the miter gate sills, pintles, and contact blocks, with the inspection report furnished to the Government. After rehabilitation is complete, the Contractor shall upright and reinstall the miter gates, along with rehabilitated cylinders and replacement anchor bars at the lower left miter gate leaf. Testing will be required in accordance with specifications. Temporary alterations to the walkways and bulkhead plate shall be repaired as needed. The work covered by this contract will consist of furnishing all equipment, labor, services, supplies and materials necessary to satisfactorily rehabilitate the Navigation Lock at the NASA SSC as specified and in accordance with the contract specifications. Particular efforts will be required to minimize the duration of any lock closure.Solicitation Number: W912P921R0036Solicitation Type: Request for Proposal (RFP) – no public bid openingSolicitation Competition: UnrestrictedNAICS Code: 237990 – Other Heavy and Civil Engineering ConstructionSmall business size standard is $39.5 millionEstimated Magnitude: between $5,000,000 and $10,000,000The closing date and time for submission of offers will be contained in the solicitation package.
