Stringless Curbs and Gutters

Summers-Taylor’s Tennessee Highway 75 project is a 4-mile stretch requiring placement at various locations of concrete curbing and gutters, for drainage and catch basins.

The Topcon 3D GPS machine control on the Gomaco GT-3600 slipform paver eliminates the need for stakes and stringlines.

A pair of Topcon PZL-1 transmitters are placed 500 feet apart to track the position of each receiver on the curb machine and relay curb location and elevation data to the paver. As the machine progresses, the transmitters are leap-frogged to maintain the slip-form production flow.
