Big-D was selected to complete earthwork, micropiles, structural concrete foundations (mat slabs, piers, slabs), etc. for this monumental, one-of-a-kind facility to extract, process and package molybdenum and rhenium. The MAP facility included eight structures, some as tall as 10 stories. The project was challenged with multiple revisions to the contract drawings during the course of construction making constant communication and coordination with the entire team critical.
