Question 1: Are the design deliverables dues with the bid package or after contract award? (4.0 Task 1

Third paragraph, Deliverables “The contractor shall provide attachment and support details for the traveling screen and powered conveyor system, electrical diagrams/schematics, plumbing diagrams/schematics, equipment specifications (including attachment and support requirements), installation specifications, etc., for inclusion in Reclamation’s future installation contract.)

Answer 1: These Deliverables will be provided within 6 weeks after contract award as described in the next paragraph (Schedule)

Question 2: When is the planned award date?

Answer 2: From the cover page, proposals are due January 11, 2024. It is the governments intention to evaluate proposals and award a contract as soon as possible. This process typically takes 4-8 weeks.

Question 3: Are there a minimum number of bids required for award?

Answer 3: There is no minimum but multiple bids are anticipated.

Question 4: Is the conveyor system belt driven or a chain drag system?

Answer 4: Statement of Work/Specifications paragraph 3.0 OBJECTIVES, third paragraph 6.b. “Chain drag type conveyors are preferable to belt conveyor systems.” Either type of system is acceptable, but the chain drag system will be favored in the proposal evaluations.

Question 5: Can you provide a list of vendors who would supply a chain drag conveyor system?

Answer 5: Reclamation does not have a list of vendors who would supply a drag chain conveyor system.

Below are some pictures of a debris conveyor at a nearby screening facility which has performed well over several decades. A similar type of conveyor which utilizes chains on either side with a drag bar is preferred. The chain type does not need to be exactly as shown in the pictures below.

Question 6: What is the length of conveyors to be provided?

Answer 6: The flat portion of the conveyor is approximately 190 feet and the inclined portion is approximately 24 feet in length.

Question 7: Is the conveyor system one section or two?

Answer 7: The conceptual design has the conveyor in two sections, one being the flat portion and the other being the inclined section. The conveyor could be one continuous system if the vendor believes that to be the best option.

Question 8: Does each screen have an individual water supply source?

Answer 8: There will be one water supply source that will provide pressurized water to all the screens.

Each screen will have an individual control valve that will turn on the water for that screen.

Question 9: Are the valves controlling the cleaning water for each screen part of the SCADA system to be provided?

Answer 9: No, the control valves will be part of the pressurized water system that will be provided through construction contract.
