Backed by the corporate strength of one of the nation’s largest contractors, Kienlen Constructors was formed as a return to Alberici’s roots in self-performed construction. Stemming from a need to deliver one-off projects with short turnaround times for loyal Alberici customers in the St. Louis area, Kienlen quickly developed a reputation for providing superior reliability and safe, quality craftsmanship.
Today, Kienlen proudly offers services performed by skilled craft workers directly to project owners or under subcontract to many leading general contractors throughout the Midwest. Kienlen is organized to effectively manage self-perform projects of any size. Our project management personnel maintain an exceptional level of constructability expertise to help complete projects on budget while minimizing interruptions to ongoing operations. Kienlen also understands the importance of efficiently coordinating with other trade contractors to eliminate delays and ensure safe, on-time completion.
Kienlen prides itself on maintaining a large trade pool with diverse talents and tenures. We continually educate and train our employees in safety, quality, productivity, and technologies.
In addition to unrivaled performance and professionalism, Kienlen has access to substantial equipment resources, cutting-edge technology, detailed administrative processes, and the financial support and bonding capacity of its ENR Top 40 parent company. This ensures that Kienlen’s clients and owners are protected against financial risk.
Kienlen’s standalone status as one of the region’s most trusted contractors has resulted in a growing portfolio that includes work for owners such as BJC HealthCare, Boeing, Nike, the U.S. Army Corps of Engineers, and Washington University in St. Louis. Kienlen is also regularly called on to perform key scopes of subcontracted work for leading prime contractors, including ARCO, Clayco, McCarthy, Paric, Rhodey, and S.M. Wilson.
