Who We Are


Alliance Construction brings 50+ years of earthwork and excavation experience to Sioux Falls and the surrounding area. We focus on a variety of commercial earthwork projects, site preparation and development, street and highway work, demolition, and underground utilities.


Behind our decades of experience, we have gained trust of many local contractors while building long-lasting relationships. We have knowledge and understanding of the dirt work industry; combine that with our strong reputation of being reliable and genuine, we are trusted to get the job done right. We want to ensure our customer's expectations are not only met, but exceeded.


Alliance Construction stands behind Tom Wiseman and Merlyn Brockhouse, our two dedicated owners who strive to deliver a high-quality service to our clients, while supporting employees to grow personally and professionally. Tom and Merlyn create an environment where everyone is valued and appreciated, so Alliance can continue to be a successful team.

"Working at Alliance has been a blessing for me and my family. Not only am I able to be home every night, but Alliance also has a positive culture, that supports a work, homelife balance."
