Our History

Weisz & Sons Inc. was formed and incorporated by Bernie Weisz in 1976. This year marks our 40th anniversary of serving North Dakota’s general contracting needs. In 2006 Weisz & Sons became a licensed Redi-Rock dealer, completing its first project at Whispering Bay within the year. This decade we have been fortunate to prosper along with the communities of Bismarck and Mandan, leading many projects contributing to our budding infrastructure. From contstucting a MSE Wall at the new Memorial Bridge to building the levee for the city of Mandan during the historic floods of 2011, Weisz and Sons has been a trusted and proven contractor.

Our Mission Statement

Our company mission is simple and guides everything we do:

“We are committed to adding value to our community and customers by completing our projects on time, safely and within budget.”

Our Safety Culture

At Weisz & Sons safety is a core value. In fact, the safety of our customers and employees is Weisz & Sons’ top priority. Whether performing scheduled maintenance in our shop or working on site at one of our projects, our employees are always encouraged to put safety first at all times.

Weisz & Sons follows all precautions at our job sites by providing PPE for all of our employees and through Tool Box Training and leadership communication. We provide our employees the opportunity to participate in ongoing safety education through training and courses offered outside of the company. We are proud members of the NDSC and partner with them for much of our ongoing education and training. We also participate in many safety programs through WSI, striving to make Weisz & Sons a safe and healthy organization, not only for our employees, but also for the communities we live and work in.
