Project Highlights

  • Boldt served as the construction and erection contractor for the project, managing more than 1.1 M tradespeople hours over the course of the project, with as many as 350 tradespeople on site at a time.
  • The Boldt team worked to overcome unique challenges due to the positioning of an adjacent, 200 MW operating unit, the location of the coal silos and the need to schedule work around outages of the Unit 1 GSU transformers.
