Wilson, along with HDR Engineering, performed construction and engineering services to complete a substation EPC package for Grant County PUD, which was specifically labeled a “Progressive Design-Build.” This option provided all parties adaptable, efficient planning and construction solutions that provided timely services without sacrificing safety or quality.

The overall project package consisted of two new substations, expansion of two substations and rebuilds of three more, all within a 24-month period.

Substations:

  • Nelson Road Substation #2 115kV
  • Babcock Substation 115kV

The HDR-Wilson team led the project under a single team that included the same key personnel for all seven substations.

Work began in June 2016, and as work progressed on the first substation, HDR-Wilson, together with Grant County PUD, worked on design and logistics of the next substation.

Various tasks included:

  • Public utility studies, coordination and site surveys
  • Geotechnical engineering and testing
  • Validation of site conditions and the client’s budget
  • Project design
  • Coordination and installation of client-provided equipment
  • Cost estimating and reporting
  • Value engineering
  • Lifecycle cost analysis
  • Design and construction scheduling
  • Permitting
  • Project closeout and documentation
  • Device configuration and commissioning including but not limited to HV and LV testing and acceptance.
