Electrical improvements planned to replace 62-year-old equipment at Barton Pump Station
(This story has been corrected to note the approved contract changes are for work at the Barton Pump Station and not related to any work ongoing or planned at Barton Dam.)
The Ann Arbor City Council voted unanimously Monday night to approve a $448,675 amendment to a contract with Stantec Consulting for the Barton and South Industrial Pump Stations Electrical Improvements Project.
Senior utilities engineer Brian Steglitz told council members in a memo the project is identified as a high priority in the city's approved Capital Improvement Plan.
The project calls for replacing aging electrical switchgear at the Barton Pump Station that dates back to 1949. Steglitz said the switchgear is not compliant with current national electrical standards and creates a safety hazard for staff.
In addition, spare parts are not readily available, and in the event of a failure it would be difficult to repair, Steglitz said. Failure of the equipment, he noted, would jeopardize the Water Treatment Plant's ability to provide a sufficient quantity of water to city customers.
The council initially approved a $128,650 contract with Stantec last year to complete the study phase of what was then known as the Barton Electrical Improvements Project.
Steglitz said the changes approved Monday cover the balance of the engineering services required to complete the Barton and South Industrial Pump Stations Electrical Improvements Project. The total value of engineering services with Stantec is now $577,325.
Additionally, the council is setting aside a $50,000 contingency for change orders to the contract with Stantec to be approved by the city administrator.
Funds for the project are expected to be advanced from the Water Supply System to be repaid pending the sale of water revenue bonds via the Drinking Water Revolving Loan Fund.
Steglitz said the Barton Pump Station is located downstream of Barton Dam. He said the approved contract changes are for work at the Barton Pump Station and not related to any work ongoing or planned at Barton Dam.
