Neumann Brothers

What Neumann Brothers does

Neumann Brothers is a privately held, family-owned general contractor founded in 1912 and headquartered at 1435 Ohio Street in Des Moines, Iowa. The company employs 101-250 staff and self-performs key construction trades including carpentry, millwright work, and operating engineering, alongside contracted labor. Service offerings span new construction, design-build delivery, tenant improvement, historic restoration, plant services, and millwright services, supported by pre-construction planning and construction management capabilities.

The company generates revenue through project-based engagements, primarily lump-sum contracts, negotiated contracts, and design-build delivery methods, with pricing quoted per project rather than via standardized or public rate cards. Its customer base is diversified across government and municipal, commercial and corporate, industrial and manufacturing, education, and hospitality and entertainment verticals, with named clients including Farm Bureau, Iowa State University, Polk County, Iowa Army National Guard, Musco Sports Lighting, SACMI USA, Science Center of Iowa, and Iowa Speedway. Project values appear to range from under $1M for small tenant improvements to $50M+ for large institutional and campus work, such as the 340,000+ SF Farm Bureau headquarters renovation across 15 phases and a 47,000 SF Armed Forces Reserve Center.

Geographically, Neumann Brothers operates exclusively within Iowa, using direct sales and project-based engagement with architects, developers, and end clients. The company maintains a recurring network of architecture firm partners across multiple firms and regular work with state and local government clients. The underlying technology stack is conventional for the construction industry, with no proprietary platform, no AI/ML capabilities, and no digital product surface; differentiation is delivered through self-perform trade labor, historical brand reputation, and multi-phase institutional execution rather than technology.
