Agenda Title:

Council action is recommended to approve a change order to a purchase order between the City and Black & Veatch in the amount of $129,000.00 for an amendment to do an addition of Lime Slaking Equipment for a Lime Silo at the Courtney Bend Water Plant for the Water Department.


Council action to approve a change order.


The City issued purchase order 21000458 on October 20, 2020 for a Lime Slaker addition at the Courtney Bend Water Plant for $446,406.00. Lime slakers are used to feed lime to the well water, which removes minerals and provides the softening process for the water.

The Water Department is preparing to add an additional lime slaker to the lime silo at the Courtney Bend Water Plant. Black & Veatch was hired to design an addition to the existing building and placement of the lime slaking equipment. Upon review of the project, the Water Department decided to increase the size of the additional slaker to add redundancy for the lime slaking process. This contract change also provides for construction phase services that will be needed to connect the new slaking equipment with the existing SDADA system and adds a catwalk extension to connect the lime silo with existing treatment basins.

Black & Veatch was selected per State Statute 8.285, et seq, which calls for seeking architectural, engineering and land surveyor services based on qualifications. The Purchasing Division issues a Request for Qualifications every three years and has established a qualified list for such services.

Fiscal Impact:

Fiscal Impact is $129,000.00. Funding is included in the Fiscal Year 2021-22 adopted budget, Page 197, Project String 401608-C, account number 7040-5406.
