Wanzek Construction

Wanzek Construction is an engineering, procurement and construction (EPC) contractor for power-generation facilities. Founded in 1971 by civil engineer Leo Wanzek and Janet Wanzek, the firm has spent more than 50 years building infrastructure for the energy sector, with a focus on helping to develop a more sustainable energy system. It is headquartered in Fargo, North Dakota.

The company's work spans wind power, solar energy and energy storage, alongside heavy civil and concrete construction. Its services cover the full project lifecycle: development and turnkey construction of power-generation facilities, followed by maintenance, expansion and shutdown services for renewable assets already in operation.

Wanzek was acquired by MasTec in 2008 and operates as a platform company within the MasTec Clean Energy & Infrastructure group. It retains its own identity, culture and operating structure under MasTec ownership.

Operating practice at Wanzek is built around its people, continuous training and modern technology and equipment. The firm applies a Zero Injuries safety culture across its own employees as well as suppliers and subcontractors, and places emphasis on safe execution, schedule performance and long-term project value.
