I-73 Greensboro Outer Loop
Guilford County, NC
Project Description
Summit is the prime consultant for the I-73 Design-Build QA/QC contract. Summit provides assistant resident level staff and below. This project is a 10.5 mile section of the Greensboro Outer Loop on new location. The project consists of 14 bridges, six culverts, and sound and retaining walls. Some of the bridge structures are specialty type bridges, one of which is for the PTI airport taxiway. Many portions of the construction are located in extremely environmentally sensitive areas, which require delicate procedures in order to preserve local ecosystems. Staff level is in excess of 25 technicians and engineers. This project contains 36,000 LF of micro-piles, the largest on any project within the state of North Carolina. These micro-piles are used as replacement for standard H-pile or drilled shafts. Summit also provided surveying services for this section of I-73, as well as surveying grade verification.
