Zachry Group delivered a two-train polyethylene unit that is part of a new $7-billion chemical complex in Gregory, Texas. At the time of groundbreaking in September 2019, it was the largest producing facility of its kind.
The polyethylene unit was designed to be 85% modularized. Modules were precommissioned and shipped to site, which reduced the startup schedule. Schedule was further optimized by completing subsurface utilities and foundations while modules were erected in another location on site.
