Ground Improvement – Installing Vibratory Stone Columns

PROJECT OVERVIEW

A local district was attempting to build a new intermediate school on ground that wasn’t stiff enough to support the building’s structure. The soil was sandy, located near the banks of a large body of water. The district reached out to CNC Foundations for a soil stabilization solution. Beyond the existing geological issues, the school district was also very cautious of outside contractors. Our staff prioritized making a good first impression with a group of people whose previous out-of-town contractor experiences had made them suspicious.

THE SOLUTION

We provided an aggregate pier/vibratory stone column (VSC) solution to stabilize the soil. Aggregate piers are stiff columns of stone that we compacted into the ground to reinforce soft soil. The columns are installed in groups to increase bearing capacity and limit settlement under the footing. Aggregate piers/VSCs are an efficient and cost-effective solution for poor soil conditions.

THE RESULTS

CNC Foundations installed over 11,000 linear feet of aggregate piers under the foundations to ensure proper building support. We completed the project in under two weeks, meeting the deadlines and allowing concrete contractors to begin pouring foundations. With help from CNC Foundations, the district was able to construct their new school with the confidence of CNC’s ground improvement work.

Was the Client Satisfied?

As mentioned above, the local school district expressed caution about dealing with an outside contractor. The experts at CNC Foundations took their concerns seriously, making clear communication a top priority throughout the installation process. Our on-time completion and overall professionalism during the project left a lasting impression, as shown by these two reviews:

“I wanted to take a moment to send this email to recognize the exemplary efforts put forth by the CNC team in completing the ground improvements for the new intermediate middle school. The timely response to site condition issues by your engineering staff to the dedicated efforts of the field crew all displayed what a truly professional company CNC is. It was a pleasure working with your team and we look forward to working together again in the future.”

“CNC is the fourth out of region company we have encountered this year providing ground improvement. We found CNC to be professional at both office and field levels, and were easy to communicate with. Typically we cringe when we see an out of area firm working in this field, however CNC was the exception and we appreciate their work on this project.”
