The information below consists mostly of clarifications or very nuanced changes. To draw

Q: Is only the electrical contractor required to be ICC certified, not for the site and
concrete work?
A: That is correct. Just the electrical contractor is expected to have the ICC
certification for Electric Vehicle Charging Stations.
Q: Does the electrical contractor need to be the prime contractor?
A: No. The site contractor or the electrical contractor can be the prime.
Q: Sheet 3 of the plans stating that (3) 125 amp 3 pole breakers are required. Is that
correct.
A: This is a typographical error and should state that 2 are required.
Q: Since Chargepoint is furnishing and installing the charger equipment under contract
with with the City, when would the Contractor have to be EV certified and go through
Chargepoint training?
A: EV certification is a separate thing from Chargepoint training. Ameren requires the
ICC Certification for EV work which must be done prior to the award of the contract.
The Chargepoint training should be completed prior to installation of their
equipment but is not required prior to award of a contract.
Q: Is there a specific color we are to use on the striping and EV Charging Logo?
A: White
Q: Is there a specific logo you require for the EV Charging parking stall?
A: Any markings that indicate EV Parking are expected to be acceptable. Contractor to
submit for approval.
This question brought to the City’s attention that signage is appropriate for the
charger. This addendum also adds the requirement to mount the following sign to
the southernmost bollard. The sign shall have the MUTCD designation of R7-111 and
be 12”x18”.
Q: Is vapor barrier required under the slab or other concrete?
A: No.
Q: Is there a specific diameter of bollard you are requiring to be placed in front of the
charger?
A: 6”
Q: Are we to supply the parking block in the one slot? Only the one or do you want one
in the future slot as well?
A: There are no parking blocks for this project. It was inadvertently left on one of the
plan sheets.
Q: Are we requiring project fencing around this during construction?
A: No.
Q: Do we have a detail or spec on the subbase under the slab, sidewalk and
foundations?
A: The initial plans and specifications did not require Aggregate Subbase. With this
addendum we are adding the requirement of 4” of compacted crushed aggregate
meeting the IDOT CA6 gradation. This applies to pavement, sidewalk, and concrete
foundation.
