Featured Project
NCDOT Complete 540 (R-2829)
The NCDOT Complete 540 project, spanning multiple counties in North Carolina (Wake and Johnston), is part of the NCDOT State Transportation Improvement Program (STIP). The three project segments that are included in Complete 540 are R-2721, R-2828, and R-2829. These segments extend from the NC 55 Holly Springs Bypass to I-40 near the US 70 Clayton Bypass (Southern Wake Freeway) and then to I-495/US 64/US 264 Knightdale Bypass.
Our Geotechnical Engineering team has provided services for the R-2829 segment of this project. The work that our team has provided included a preliminary geotechnical field investigation and inventory reports for 13 miles of the proposed NC 540 alignment. This geotechnical field investigation and inventory reporting also included 8 associated bridge structures. The geotechnical services that we provided went from I-540 to Quarry Road, east of Garner, North Carolina.
Our Team Has the Experience
Our experienced team of engineers, geologists and drillers will uncover everything you need to get your project off the ground. With three drill rigs in-house and a staff that has experience from thousands of geotechnical investigations across the region, we can mobilize a professional team and the most appropriate rig to your site. Our accessibility will be your asset, as will our two state-of-the-art, AASHTO and CCRL certified testing labs. Soil is our forte, and we are up to any challenge, no matter what type you’re trying to build on.
