The contractor hired to build three wind farms in Converse and Carbon counties has won a $1.4 million judgment against a dirt subcontractor for construction delays and costs.

A federal jury recently sided with Tetra Tech EC Inc. in its case against California-based Jerry Herling Construction Inc.

The jury determined that Jerry Herling Construction breached its contract by failing to pay its vendors. Some of those vendors are Wyoming businesses.

Tetra Tech is based in Pasadena, Calif.

PacifiCorp hired Tetra Tech in early 2008 to build the Glenrock and Rolling Hills wind farms in Converse County, and the Seven Mile Hill wind farm in Carbon County.
