In order to achieve this goal, the City is required to allocate annual capital funding to cover the cost of these mandated repairs.
On October 17, 2022, the proposal was posted to BidsOnLine, and thirty-four (34) prospective bidders downloaded the bid information. On October 26, 2022, a mandatory walk-through was conducted with Veolia staff and eleven (11) participants. On November 22, 2022, four (4) bids were received from (in alphabetical order): Cratus, Inc., D’Arcy and Harty Construction, Inc., Glosage Engineering Inc., and W.R. Forde and Associates.
