When you encounter unstable soil, you usually get a bulldozer to cut down until you get to solid ground. No matter how far down we got, the soil was still unstable. We had to bring in two or three feet of fill to make the site stable.

A 500,000-square-foot building with one floor was unusual 10 years ago. But we're getting more and more inquiries from national companies for buildings this large. We had an inquiry last month for a building with 700,000 square feet. They're getting bigger.

The soil was unstable. We had to get it corrected. It cost us a lot of time and hundreds of thousands of dollars.
