Replacement of Intake Tower Cylinder Gate Stem Assemblies IDIQ

The Bureau of Reclamation (BOR), Interior Region 8: Lower Colorado-Basin, has a requirement to replace the gate stem assemblies of up to 4 of the intake towers at Hoover Dam with corrosion-resistant stem assemblies.

This is a 5-year Indefinite Delivery-Indefinite Quantity (IDIQ) type contract. This procurement involves both supply and construction work. The goal is to replace the gate stem assemblies of up to 4 of the intake towers with corrosion-resistant stem assemblies. The original stem(s) will be tested, under a different contract, to determine the stems structural integrity. The results of testing may establish the feasibility of replacing, repairing, or keeping the remaining gate stems located at the other intake towers.

Delivery orders will be issued for ordering the gate stem assemblies and task orders will be issued for the removal of the existing gate stem assemblies and installation of the new gate stem assemblies. Delivery orders and task orders may be issued independently from each other, at the same time, or under one order.

The contractor must furnish all engineering, materials, labor, tools, equipment, transportation, supervision, and inspections to replace the original cylinder gate stems and associated parts for one Intake Tower. The old stems shall be removed and replaced with new stems, in-kind, with respect to dimensions and mechanical properties. Replacement of the stem includes all the associated parts needed for a complete and functioning stem. The associated parts include but are not limited to studs, bolts, nuts, pins, connecting rods, coupling flanges, the driving stem sections, the guide brackets, guide collars, and the connection parts to the cylinder gates.

1. Fabricate a complete set of corrosion resistant cylinder gate stem assemblies. Note: the stem tubing is not a conventional pipe size and will require a special run.

1.a. Fabrication methods shall demonstrate test results that meet or exceed all minimum strengths and elongation requirements.

2. Assemble sections of fabricated stems at the contractor's facility for inspection by Hoover personnel if requested.

3. Prior to the penstock outage, number, match mark, disassemble, and deliver to the Hoover Dam warehouse for staging in preparation of gate stem replacement.

4. Remove existing set of stems. Match mark and label each stem piece as it is removed. Deliver to Hoover Dam Central Warehouse for storage.

5. Install new set of stems.

6. Provide a complete set of as-built drawings in both electronic and hard-copy forms for one complete set of gate stems.

7. Provide commercial pipe racks at the Central Warehouse Yard and neatly stack the removed system on the pipe racks.

8. Acceptance testing: Full travel test, up and down, of reassembled stems and gates. The contractor and Hoover Dam personnel will test the new cylinder gate stems by raising and lowering both the upper and lower cylinder gates, followed by a re-inspection of the stems.

An alternative approach in reference to design and installation is welcomed; however, all portions of the statement of work must be addressed prior to submittal of any alternative approach. Contractors must take into consideration the limitations of crane travel, loads, and material properties.
