Submit Construction Bids



Since 1982, Brosz Engineering strives to build a strong reputation for developing quality yet economical civil engineering and surveying solutions for our diverse clientele base. As a general consulting engineering practice, Brosz provides services for municipal, county, state, federal, and tribal governments. The firm also serves airport boards, oil and energy clients, rural water districts, and private developers. Planning and engineering projects for private sector clients include commercial, industrial, mixed- use, and residential developments.

We deliver projects from concept to completion in all aspects including surveying, right-of-way acquisition, design, environmental coordination, bid documents preparation, bid letting, construction management, and project close-out. Consequently, a large portion of our work focuses on construction engineering services. This includes administration, field observation, construction staking, materials testing, asphalt and concrete mix designs, permitting, and more. Most of our office locations contain certified materials testing labs with the ability to perform aggregate gradations, soils density testing, asphalt QC/ QA testing, and concrete testing.

In summary, our strength is in our people, with over 120 team members located across nine offices. Our engineered solutions are founded on what most of our clients tell us are their top three priorities – quality, time and cost. Brosz clearly understands the importance our clients place on these three attributes. But above all, the Brosz team places customer service as our highest priority. And, we believe our success is ultimately measured in terms of customer satisfaction.


Dan Brosz founded Brosz Engineering in Bowman, North Dakota, and committed nearly 40 years of his life to running the business and serving area communities. Building a legacy of entrepreneurship, he expanded operations to provide services across North and South Dakota and reached into neighboring states. After its initial formation in Bowman, the firm opened an office in Pierre in 1992, and then moved into Sturgis in 2002.  Dan retired in January of 2020 after having committed a life-long effort to create an organization that currently has nine offices across the Dakotas and Montana. But even more, Dan was passionate about serving clients and making communities better.  When discussing the Brosz team, he was always proud to declare, “We have the hardest working, conscientious, customer-first, and fair-minded staff in the industry. Because of these qualities Brosz can provide high-quality services and products at a reasonable fee.”  Dan’s legacy continues today as we strive to maintain the reputation that the company established throughout its many years of operation. We aim to provide quality engineering and surveying services by developing cost-effective solutions for our client’s need and impacting our communities for the better.
