Questions and Responses Question1: Is there any incumbent/recompete or is this a brand-new project? If yes, could you please provide us with their award number or even if the customer bought similar services in the past.

Response: This project is considered a brand-new project. The work involves the abandonment of an existing unsafe sewage pump vault and the installation of a new above-grade sewage pump vault and pumping system at Merced National Wildlife Refuge to improve safety and operational reliability.

Question 2: Are there any existing photos of the site and vault that you can share?

Visual reference would help us better assess access, layout, and overall conditions.

Response:

Question 3: Additionally, could you provide the specifications for the following:

1) Vault

Response: Currently presume cast iron or different type of metal made. Dilapidated and in need of replacement

2) Pump

Response: ½ horsepower pump

3) Alarm system

Response: Currently there are no alarm systems for the current vault pump

4) Electrical panel

Response: 200 Amp panel

Question 4: Regarding the pump installation, can you confirm whether the pump is mounted on guide rails, suspended, or set directly on the base of the vault?

Response: It is set directly on the base of the vault

Question 5: Do we know the invert depth of the pipe entering the vault from the house?

Response: Approximately 18 to 28 inches.

Question 6: Is there going to be an emergency bypass line in case the house loses power and the vault fills up? If so, how will that be designed?

Response: It only requires installation of a pump, float system, and high-level audible/visible alarm.

In the event of power loss, the system relies on storage capacity within the vault and the high-level alarm to alert personnel.

Question 7: Do we know the elevation change and distance from the pump vault to the septic leach field? This information is needed to calculate the total dynamic head

(TDH).

Response: The Contractor is responsible for field verification and determining TDH as part of their installation and equipment selection. The distance to the septic leach is approximately 35 -50 feet and elevation change is approximately 2-3 feet.

Question 8: Do we know the storage requirement for the pump vault in gallons?

Response: The Contractor is expected to furnish a vault “designed for wastewater applications” and compliant with safety and operational needs, the current pump vault capacity site at 500 gallons.

Question 9: Do we know if we are going with a duplex pump station or single pump station?

Response: This is single pump system, Question 10: Are we trenching new power and conduit back to the main house panel?

Response: The contractor may use existing electrical infrastructure. The Contractor should assume responsibility for providing a complete and code-compliant electrical connection.

Question 11: Will the contractor be responsible for bypass pumping during construction while the existing vault is abandoned? It appears that the existing pump station is already not functioning.

Response: If maintaining service will be necessary, the Contractor will provide temporary bypass pumping

Question 12: Are there any requirements for telemetry, autodialer, or remote alarm notification for the pump station?

Response: Only requires:

• Audible alarm

• Visible alarm
