About this file
This is a Questions & Answers document for Solicitation 140G0126R0006, a USGS Flagpole Lighting Installation contract. The document does not address specific products or services required, pricing terms, response dates, or award information. Instead, it clarifies technical and procedural requirements for the electrical installation work.
The Q&A addresses four key topics: (1) circuit tapping procedures, requiring the conduit to enter concrete below grade with the tap made in the air intake vault, using a NEMA 4 box, and ensuring proper penetration sealing upon completion; (2) engineering requirements, which are limited to electrician confirmation that the circuit and power panel are not overloaded, with additional engineering guidance available upon request; (3) and (4) power shutdown procedures, confirming that contractors may turn off power during daytime hours and that circuit shutdown is mandatory prior to any work for safety compliance.

Questions & Answers Solicitation 140G0126R0006
USGS Flagpole Lighting Installation
1. Upon walking today we were told to tap off existing circuit outside where the LB is located, is that correct?
a. Correct, the conduit should enter the concrete below grade, and the tap should be made somewhere in the air intake vault. Once installation is complete, make sure the penetration is properly sealed. It’s important to use a Nema 4 box at this location to meet requirements.
2. Does tapping off existing circuits need engineering?
a. It’s expected that your electrician will confirm the circuit and power panel are not overloaded. If any additional engineering is required beyond this assessment, just let me know the specifics so I can provide further guidance.
3. Can we turn off power during the day to tap off circuit?
a. Yes, you can turn off the power during the day to tap off the circuit. In fact, the circuit must be shut down prior to any work for safety reasons.
4. Do we need a shutdown?
a. The circuit must be shutdown prior to any work.
