"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.”
