EV Charging Station for the Northland Transit Center

RFI Questions: 1. Are there any existing drawings of the Northland Transit Center Project?

2. On the drawings sheet E-003 and Coded Notes #2: along the trench line locations, there are two

(2) trees and one (1) existing sign in the way. There are no coded notes to remove and/or relocate these trees. Are these trees to be removed and/or relocated? If yes, please provide the location on the drawings. Also, is the existing sign encased in concrete below grade? See pictures below.

3. The new EV Charging Station concrete pad is 46” x 30” as shown on the drawings E-003 and coded notes #6 that is to be located in between the existing concrete curb and metal fence. The distance between the concrete curb inside edge and to the front side of the metal fence is approx. +/- 28”. There’s now indication on the drawing to remove and reinstall for the pad installation or to modify the new pad so that it fits within the +/- 28” gap. See pictures below

4. The existing fence will be an obstacle for a trenching machine to maneuver along the parking lot island. Can we remove the fence? Are the fence posts encased in concrete below grade? What is the min. trench width and depth for both direct burial conduit and concrete encased duct bank? See picture below.

5. The trench line shows on the drawing going thru in between two existing bollards by the sidewalk area. Can you provide a detail of the bollard footer? What is the thickness of the existing concrete drive (assuming min. 8 – 10” thick), curb and sidewalk slab? See picture below.

6. Is the permit and inspection fees by the contractor or Advanced Engineer Consultant will provide a blanket permit and inspection fees for this project?
