2. Question: Section 3.1.4 Wiring: Please clarify, “All Wiring power and control wiring shall be new”, specifically does this mean the home run from the electrical panel inside the building to the sewage pump control pane shall be replaced using the existing conduit or just all the power and control wiring associated with the new pumps and control panel?

Answer: New wiring for pumps and control panels only.

3. Question: Section 3.1.4 Wiring: Is the government aware of any electrical deficiencies currently?

Answer: It is unknown of any electrical deficiencies, however, anything outside the current scope of work will be treated negotiated as growth work.

4. Question: Section 3.2.1 Existing Conduit: During the site visit it was observed that the 3” conduit that penetrates the concrete cover is broken. Should the contractor include the cost of repair/replacement as part of this scope of work, or will the government repair/replace the broken conduit prior to the award of this contract?

5. Question: Section 3.4.1 As-Built Drawings: Will the awarded contractor receive a copy of the current drawings from the government for the purposes of meeting this Deliverable or will the control drawings for the new duplex pump system suffice?

Answer: See the provided drawing “C7019C03ASB.DWG”.

6. Question: Section 3.4.1 As-Built Drawings: Standards: “only full-sized AS-BUILT drawings are acceptable”, please clarify if the manufacturer provided control diagrams, like those currently mounted inside the existing cabinet will be acceptable.

Answer: See the provided drawing “C7019C03ASB.DWG”.

7. Question: Section 3.4.2 Equipment Enrollment: Will the government supply the awarded contractor a copy of the Equipment Enrollment Form spreadsheet for deletion/addition of the duplex sewage ejector pump system as detailed in this Scope of Work?

Answer: Yes

8. Question: Section 15.1.C Safety Requirements, Responsibilities, Confined Space Permit:

the Scope of Work specifies the confined space clearance must be conducted by a certified marine chemist. Should the contractor include the cost for this professional or is there a certified marine chemist assigned to the Station that will perform this function, much like is described in

Answer: The Coast Guard will not be providing a Marine Chemist and the contractor shall include this in their fully burdened firm-fixed price quote.

9. Question: The scope of work (Section 3) requires furnishing and installing two 1.5 HP 230V

1-Phase sewage lift pumps, a new NEMA 4X stainless steel control cabinet, new electrical controls, and associated wiring. These items are typically not stock items and have manufacturer lead times ranging from several weeks to months depending on current supply-chain conditions.

Could you please clarify whether the Government will accept a reasonable equipment procurement lead time as part of the performance schedule?

Answer: The Period of Performance (POP) has been revised within the SOW provided with this amendment.

11. Question: Can the government please provide existing pumps manufacturer, model and serial number?

Answer: This information is not available currently.

12. Question: What is the system design pressure and flow?

Answer: Provide a sealed mercury float switch control system as indicated. Automatically alternate operation from one pump to the other and start second pump in the event first pump cannot handle incoming flow. Provide manual "on-off" switch for each pump.

16. Question: Will bypass pumping be required or can the work be completed during low flows, overnight or on weekends?

Answer: Yes

17. Question: Please confirm the required pump performance, including gallons per minute and total dynamic head.

Answer: Provide a sealed mercury float switch control system as indicated.
