BLACK AND VEATCH

Client: Black and Veatch

Objective: Combined Cycle Power Plant

Timeline: 700,000 man-hours over an 18-month period

Project Overview: GMC hired and managed all crafts to install two 165 MW Combustions, two Heat Recovery Steam Generators (HRSGs), and one condensing steam turbine. We also installed the balance of plant equipment and piping that was roughly 30,000 lf, including heavy wall pipe for main steam and P91 chrome piping. The combustion turbine operated in simple-cycle mode for 4 months until the plant eventually converted to combined-cycle operations.

"Rohlfing and his lead foremen Jeff Kneemiller really took ownership of the project, especially during the 24-hour period when the tie-ins were made to the existing plant. This was completed in the middle of the night when treatment flows were lowest, 2 hours ahead of schedule. This gave the plant a few additional hours to troubleshoot any issues between the interface between the old and new sections of the plants.”
