Concrete contractor and tilt-up entrepreneur Larry Clark discusses the construction of Capital Centre, an all-tilt-up sports and entertainment complex he is building in Lansing, Mich. The facility includes a 52,000-square-foot basketball stadium, a 176,00-square-foot building for soccer, hockey, and gymnastics, and a health and fitness building with an indoor running track. For the walls of all three buildings, Clark is using more than 180,000 square feet of tilt-up sandwich panels as tall as 45 feet.
The Romans built nearly 53,000 miles of roads linking the capital to their far-flung empire. To put this amazing feat in context, consider that the United States, to date, has built 42,000 miles of interstate highways. Roman roads were remarkable for preserving a straight line from point to point, regardless of obstacles. They traversed marshes, lakes, ravines, and mountains.
