Notable Installations by the Interface Construction Corporation Team
- Removed +8,000 cubic yards of unsuitable soil to make room for 12,000 cubic yards of new soil to bring site to a suitable subgrade
- New substation enclosure of pre-cast panels with anti-graffiti coating
Interface self-performed the cast-in-place concrete and oil containment system while working outside the minimum approach distances from active, high-voltage electric lines, requiring an in-depth safety plan consisting of a full-time monitoring system.
