Q9. Please provide the electrical specifications for each of the two mobile trailers including voltage (120V/240V), phase (single or three-phase), amperage rating, panel size, and estimated total load in kilowatts. This is required to verify generator compatibility and select appropriate distribution equipment. Would this be available at pre-bid site visit?
A9. Please see attached document for electrical requirements

Q10. Will the government provide a site plan or sketch showing the approximate generator placement area, cable routing to each trailer, and proximity to pedestrian pathways? Are there known underground utilities in the grounding rod installation area, and what is the process for utility locating at this National Park Service (NPS) site? If not, is a pre-bid site visit available before the June 5 deadline?
A10. See attached document for approximate location. Exact placement is unknown but will be in the Red box. Underground utilities are unknown. Contractors must call 811 or fill out a utility-locate ticket online at least two business days before starting any digging project in South Dakota.
