Challenges

  • The project included the design and replacement of significant structural members, including the skip bridge and cold-blast main bridge.
  • The hearth walls, which had not been replaced since 1995, the stack refractory, some cooling members, and a stove shell were also replaced.
  • Various control systems had to be replaced, including the distributed control system, stove common programmable logic controller (PLC), and charging PLC.
  • A significant change in scope in mid-FEL4 had to be accommodated. The change was incorporated without issue.

Solutions

  • We provided engineering, procurement, and construction management services, including purchasing services, construction and safety management, and warehousing and materials management.
  • 3D-engineering modeling was used, included laser scanning of the existing plant areas.

Highlights

  • Engineering was completed on time.
  • The project team had to adjust to a significant change in the scope in mid-FEL4, which was incorporated without issue.
  • Construction was completed 2-½ days earlier than the planned 48-day outage, saving significant cost by avoided lost production.
