Optimizing the Design and Implementation of Ground Improvement for a 241-Acre Warehouse Development-Video

Video Transcription

Video Summary

Sonia Swift and Taylor Tull of Menard presented ground-improvement design for a 241-acre warehouse development in Linden, New Jersey. The site included eight large warehouses, roads, variable soil conditions, and existing or planned surcharges. Rigid inclusions—grouted columns used to reduce settlement and increase bearing capacity—were designed alongside methods such as dynamic compaction.<br /><br />The team tailored designs to each building’s grading and loading conditions rather than applying a single solution. Challenges included substantial cut-and-fill variations, long project duration, and transitions between supported and unsupported areas. Modeling and surcharge monitoring helped refine column spacing, diameters, and consolidation estimates. Three-dimensional analysis assessed transitions and potential down-drag forces.<br /><br />Single-element load tests verified bearing-layer capacity and informed embedment requirements. Testing supported reducing typical embedment from six feet to four, saving grout, equipment wear, and installation time across thousands of columns. The warehouses generally had an 800-psf slab load and a two-inch settlement criterion.
