Wanzek Construction

What Wanzek Construction does

Wanzek Construction, Inc. is a Fargo, North Dakota-headquartered industrial general contractor founded in 1971 by Leo and Janet Wanzek, now operating as a privately held platform company within MasTec, Inc.'s Clean Energy & Infrastructure Group following MasTec's 2008 acquisition (codenamed 'Project Zephyr'). The company specializes in turnkey Engineering, Procurement and Construction (EPC) and Balance of Plant (BOP) services for utility-scale clean energy projects, with a portfolio of nearly 21 GW of constructed power capacity (17 GW from wind alone) and over 100 named projects across 31 U.S. states. Service lines span Wind Power, Solar Energy, Energy Storage, and post-construction Renewable Power Services including maintenance, repairs, ADLS installation and catastrophic rebuilds.

The business operates as a B2B project-based contractor serving developers and utilities across North America, executing work through enterprise field sales, formal business-partner prequalification, and multi-decade alliance agreements with anchor customers such as Duke Energy and American Crystal Sugar. Revenue is earned primarily through one-time EPC contracts and ongoing professional services for installed assets; the company reached $1B in revenue for the first time in 2020 and is now embedded in a broader 2024 MasTec Renewables platform alongside IEA Constructors and White Construction. Operational footprint includes a corporate headquarters in Fargo, a Phoenix regional office (2019), and an Amarillo Renewable Services equipment and storage facility (2017), supported by a workforce of roughly 1,684 employees and a fleet that includes a 200-ton DeMag Mobile Crane — the original capability that enabled entry into wind turbine erection in the early 2000s.

The company holds founding board membership in the American Clean Power Association and is affiliated with the Solar Energy Industries Association, and has accumulated consecutive STEP Platinum/Diamond safety awards from ABC, multiple Million Work Hours awards from NSC, and consistent ENR Top 400 rankings, which together support bonding capacity and developer prequalification. A 2022 Department of Labor-registered, NCCER-accredited Construction Craft Laborer Apprenticeship Program formalizes the craft-labor pipeline that underpins Wanzek's ability to staff multi-trade, fast-paced renewable EPC projects.
