Authorization To Execute Seventh Contract Amendment With Voith Hydro, Inc. For Commissioning Services For Byllesby Dam Water-To-Wire Redevelopment Project
end
PURPOSE/ACTION REQUESTED
Authorize an amendment to the contract with Voith Hydro, Inc. to increase the contract maximum by $205,000 to $4,973,527 for commissioning support services.
SUMMARY
Dakota County owns the Byllesby Dam and operates its high-hazard hydroelectricity facility under the Federal Energy Regulatory Commission (FERC) safety regulations. Over the past decade, the Dakota County Board of Commissioners has approved significant capital investments into the project for FERC-required dam safety improvements. By Resolution No. 15-532 (October 20, 2015), the Dakota County Board of Commissioners authorized staff to execute a contract for preliminary design tasks on a turbine upgrade project to replace the existing century-old equipment in the dam.
To complete this project, County staff developed a team including an engineering consultant to provide project design, a turbine manufacturer to provide turbine and generation equipment in a complete package (e.g., water-to-wire equipment), and a general contractor for installation of the equipment and modification to the powerhouse structure. By Resolution No. 18-111 (February 13, 2018), County staff developed prequalification requirements for the turbine manufacturers through a request for qualifications, in which Voith Hydro, Inc., was selected utilizing the Best Value Contracting process authorized by State statute in the amount of $4,220,436. Voith’s first contract amendment was addressed administratively in the fall of 2019 for small changes to their design and modifications during fabrication in the amount of $76,794, bringing the total contract amount to $4,297,230. By Resolution No. 20-072 (February 4, 2020), the County Board authorized a second contract amendment for changes in the electric equipment to address powering Byllesby Regional Park and modifications in the penstocks to make construction more cost-effective. By Resolution No. 20-402 (August 18, 2020), the County Board authorized a third contract amendment for customs and duties for shipping the equipment from overseas. By Resolution No. 21-289 (June 8, 2021), the County Board authorized a fourth contract amendment for the storage of sensitive battery and electrical equipment in the amount of $6,630, bringing the total contract amount to $4,496,396.
A contract amendment was executed to update hourly rates for supervision and commissioning work for the site installation and testing. This amendment is considered the fifth amendment and was executed on March 22, 2022.
By Resolution No. 24-054 (January 23, 2024), the County Board authorized a sixth amendment for on-site installation and inspection services during the commissioning phase in the amount of $272,131, bringing the total contract amount to $4,768,526.
The costs associated with this seventh amendment are for on-site inspection, testing, and control related programming services for the remaining commissioning tasks of the project. Commissioning, which commenced in January 2026, is currently ongoing and expected to be completed in May or June of 2026. Costs for on-site support were provided within the original proposal. However, the project timeline was extended due to procurement delays requiring additional site mobilizations, and hourly billing rates have increased since the 2018 proposal.
