Kraemer Brothers

What Kraemer Brothers does

Kraemer Brothers is a privately held, family-owned commercial general contractor founded in 1948 in Plain, Wisconsin, delivering general contracting, construction management, and design-build services across a tri-state Midwest region (Wisconsin, Iowa, and Minnesota). The firm serves enterprise clients in nine verticals — education, healthcare, civic/government, food and dairy, hospitality, industrial, religious, retail, and science and technology — with particular depth in K-12 education (50+ school districts, 150+ school projects) and healthcare. It is led by President Ryan Kraemer, with more than 20 family members active across multiple generations and approximately 345 total personnel, of whom roughly 300 are cross-trained field craftspeople executing self-performed work in concrete, masonry, steel erection, carpentry, and crane operations.

The firm's core technology stack is Autodesk Construction Cloud, deployed across Building Information Modeling (BIM), 3D modeling, clash detection, project management, budget tracking, document control, and field operations. This platform supports a vertically integrated service portfolio spanning pre-construction (provided at no charge), budgeting and estimating, constructability reviews, construction execution, and post-construction services including 11-month warranty support. Specialized offerings include MEP coordination, LEED-certified green and sustainable construction (12 projects totaling ~2 million square feet in two years), safety management (zero OSHA/EPA citations in 10 years, EMR 0.68-0.87), and a niche referendum services practice supporting school districts through community engagement and pre-construction planning.

Kraemer Brothers generates revenue primarily through fixed-price and cost-plus commercial construction contracts, with self-performed trades executed directly and specialty trades competitively bid to subcontractors. Pricing is project-specific and not publicly disclosed; pre-construction services are unbundled from the construction contract and provided at no charge as a client acquisition mechanism. The go-to-market motion is enterprise field sales driven by direct relationships, reputation, and repeat-client referrals, with no indirect channels or franchise models. The firm has completed more than 1,000 projects since founding and maintains decades-long relationships with anchor clients including Sauk Prairie Schools (since 1954), the School District of Reedsburg (since 1956), and Sauk Prairie Healthcare (since 1959).
