Construction Leader

– SINCE 1919

W. A. Klinger is a Sioux City, Iowa-based construction manager, design-build firm, and general contractor. We redefine the construction experience by putting people first, communicating effectively, and building on 100+ years of excellence.

We serve healthcare, education, commercial, civic, and industrial clients throughout Northwest Iowa, Northeast Nebraska, and Southeast South Dakota. Most of our projects fall within 200–300 miles of our home office, and we welcome opportunities beyond that range.

CONSTRUCTION MANAGEMENT, THE WAY YOUR PROJECT NEEDS IT

We can serve as your construction manager in whatever role fits your project:

Construction Manager at Risk (CMaR): We join your team early to help plan and price the project, then commit to a guaranteed maximum price and take responsibility for building it.
Construction Manager as Agent (CMa): We act as your advisor and representative, guiding budget, schedule, and contractor coordination while you hold the construction contracts directly.

In either role, owners benefit from working with a construction manager who is also a builder. We bring hands-on construction knowledge into preconstruction planning, cost estimating, constructability review, and value engineering, helping owners make informed decisions before construction begins. For owners who want a single point of contact, our design-build services combine design and construction into one streamlined process.

We also self-perform key work, including demolition, concrete, carpentry and millwork, framing and drywall, infection control systems, and millwright work and equipment setting, giving us direct control over cost, schedule, and quality.

Klinger Companies, the parent company of W. A. Klinger, is the largest commercial contractor in the Siouxland region.
