A 50-YEAR TRADITION OF EXCELLENCE.

Wanzek was founded in 1971 in Fargo, ND by Leo Wanzek, a civil engineer. Although the company initially specialized in road and bridge construction, Leo’s entrepreneurial spirit set us on a path to excellence. Today, we’re a billion-dollar company and proud to be part of the MasTec family.

First Contract.

On September 14, Leo and Janet found Wanzek Construction, Incorporated, running the business from their basement home office. Leo and Janet also design the first logo, which remains a favorite with new and veteran employees.

Their first contract was an ambitious one, the visitor center at Lake Ashtabula, ND, valued at $300,000. The project was a big step for the new company and their small team. Wanzek continued to take calculated risks with a $2 million project for the Garrison Diversion Conservancy District in 1973.

New Office.

The Wanzek family buys a 30-acre farmstead outside Fargo, ND, so our corporate headquarters gets an upgrade - the garage. The family also utilizes the barns and Quonset for storage and the company shop.

First Cranes.

We purchase our first 40- and 50-ton Link Belt Crawler Cranes. Cranes became and still are a vital part of our business at Wanzek. Not only has the crane business done well on its own, but owning them has enabled us to enter new markets like the ethanol industry and renewable energy.

Taking the Plunge.

We build our first municipal swimming pools in Grand Forks and Belcourt, ND. Wanzek would help innovate the pool business with specialized construction techniques from excavation and gunite/shotcrete pool shells to the water recirculation piping, water filtration and chemical systems. We would go on to build or work on more than 60 pools over the next three decades.

A Lasting Relationship.

One of our longest-running client partnerships begins with our first job for American Crystal Sugar in Moorhead, MN. We continue to partner on their projects to this day after nearly 40 years.

New New Office.

We move out of the garage and into a stand-alone office near the Wanzek farm. The building, which stood just off the I-94 interstate, didn't have any signage, leading many drivers to wonder what it was. The building was another sign of how much faith Leo and Janet had in the growing business.

Welcome home Jon.

Janet and Leo’s son, Jon, returns to Wanzek. After graduating with a degree in Civil Engineering, Jon had struck out on his own for a time, working for Mortenson and Northwest Airlines (now Delta) for several years. The connections made and experience gained during that time would prove useful for Wanzek's future growth.

Jon and his new wife, Lori, who was also a Civil Engineer, weren't afraid to get their hands dirty for the success of Wanzek. When Jon came back, our pool building business was struggling. Both Jon and Lori went to certified pool operators class, where they learned to do everything from paint scraping to fixing pipe leaks. Jon also took over estimating, bidding and project management of the pool division.

Work with Walmart Begins.

We build our first Walmart in Jamestown, ND, followed closely by a second in Devils Lake, ND. In 1992, we build Sam's Club in Grand Forks after an exclusive negotiation. We'd go on to build seven stores for the nation's largest retailer.

1990 Walmart

First 500.

We reach a milestone with our 500th project — swimming pool in Osage, MN. The mid-90s was a period of diversity and growth for the company with expanding relationships with American Crystal Sugar and Minn-Dak Farmers Cooperative as well as new projects like constructing an assembly building for Bobcat skidsteer loaders for Melroe Bobcat.

Dig This.

Jon’s passion and vision for future diversification opportunities come to life by purchasing a fleet of cranes and the official launch of the Crane Services division in the mid-90s.

Bringing the Heavy Equipment.

Wanzek makes a big move with the purchase its first 200-ton DeMag Mobile Crane. Leo, Janet and Jon Wanzek make the decision while meeting in the family garden (a passion shared by both Leo and Janet).

Setting Up Shop.

Wanzek builds a maintenance and equipment storage shop on a parcel of land that Leo, Janet and Jon made the savvy decision to purchase years before. The location is still home to some of Wanzek’s operations today.

Change in the Air.

Wanzek was an early entrant into the wind energy construction market, building a single turbine for the City of Moorhead, MN and six other individual turbines with a private wind developer. Their expertise and scope of services grew with each project.

Strong Breeze Blowing.

Our first major wind farm is built near Edgely, ND. We built the roads and tower foundations, erected the wind turbines and finally, set the large rotor blades. Eventually, Wanzek became a full-service wind contractor, offering Balance Of Plant (BOP) and Engineer Procure Construct (EPC) services.

New Partnerships.

With the growth of the wind energy market, we solidify our relationship by signing a First Alliance Agreement with one of the largest wind developers at the time – Duke Energy.

Wanzek enters the American Cranes & Transport (ACT) list of top 50 largest crane-owning companies.

With Leo Wanzek’s health declining and Jon continuing to guide the overall vision for Wanzek, Leo makes the decision to hand the leadership reins over to Jon. Leo did this by greeting Jon at the bottom of a wind turbine, shaking his hand and telling Jon he was president and chief executive officer of Wanzek Construction. Jon happily accepted the opportunity to carry on the family’s legacy.

Turning the Page.

Leo’s death in early 2008 coincides with Wanzek’s efforts to find a company to buy the business. Coined “Project Zephyr” to keep the details confidential, Wanzek was eventually purchased by MasTec, Inc., a family-run construction business based out of Miami, FL.

Wanzek achieves $400 million in revenue for the first time.

We are ranked for the first time in the Engineering News-Record (ENR) Top 400 list coming in at #345.
