Corval Group was the design-build contractor for the expansion of Glacial Lakes Energy ethanol production facility. The expansion was executed on a “fast-track” schedule. It increased the facility production from 40 mpy to over 100 mpy. Corval also placed 2,500 cubic yards of structural concrete during the expansion. Corval Group worked closely with technology provider ICM and engineering firm SSOE to complete the project ahead of schedule. GLE awarded the design-build team with a $1 million bonus resulting from the project success.
