Northpointe Commerce Park – Lot A

Effective temporary drainage management was critical to keeping this project moving smoothly. After clearing and grubbing, the team relied on ponds, swales, and temporary ditches to control stormwater and protect active work areas.

JWC’s Hanahan sitework team worked closely with the engineering and surveying teams to raise the building pad grade, constructing a three‑acre pad more than four feet above the original elevation using onsite cut and material from the pond areas. This effort generated over 30,000 cubic yards of marginal fill and helped balance the site without extensive off‑site hauling.

To maximize the value of the 12‑plus‑foot‑deep pond excavation and reduce the cost of exporting and importing soil, JWC and the geotechnical team used chemical soil treatment with dry cement powder. This cement stabilization approach accelerated construction and addressed challenges posed by poor, wet clay soils. As a result, JWC completed pad construction in under 30 days—ahead of schedule—allowing the general contractor to begin foundation and slab work earlier.

The cost of cement stabilization was significantly lower than the expense of hauling material off‑site and bringing in replacement fill. In addition to earthwork and grading, JWC installed the water, sewer, and storm utilities, creating an efficient handoff to the vertical construction team. This proactive sequencing gave the general contractor room to coordinate other trades and supported on‑time building completion.
