Built in a valley at the edge of the Blue Ridge Piedmont region, a flattened plateau needed to be created before construction could begin. Instead of buying construction aggregate like sand, crushed stone, or gravel, Bechtel brought in a rock crusher to create the needed gravel from existing rock, which not only saved the project more than $2 million, but also reduced waste by more than 200,000 cubic yards (153,000 cubic meters).
Bechtel systematically collected data on fuel and electricity use, creating a metric of energy use per job-hour, which will be comparable across different projects. This effort will show—for this project and future ones —how much energy is being used, equipping Bechtel with more precise data to generate sustainable, cost-efficient alternatives.
The Stonewall project also procured more than $16 million of goods and services with local businesses, employed 800 local workers during construction, and created 30 permanent positions.
