Our Company

A.B. Systems, Inc. is a design/build commercial construction company headquartered in Rochester, Minnesota. We were incorporated in 1972 by brothers Karl and Peter Schuller. We are an employee-owned (ESOP) company, with 49% employee ownership, making us one of the few construction companies to participate in an employee stock ownership program. We have constructed over 12 million square feet of commercial building space in the past 45 years, and specialize in the design and construction of commercial, industrial, and institutional buildings. We have done over 2000 jobs in our company’s history, and have worked with notable companies such as Viracon, McNeilus Steel, Alumacraft, Wells Fargo, Hormel, Pepsi-Cola, Fed-Ex, Rochester Medical, Halcon, West Bank, and Tom Kadlec Honda.

We have our own Architectural Drafters, Architectural Designers, 3D Modelers, and an On-Staff Architect, and we partner with the best civil, structural, mechanical, plumbing, and electrical engineers. During construction, we have our own steel erection, carpentry, and roofing crews, and partner with expert sub-contractors, while overseeing all divisions of the project as the general contractor.

A.B. Systems, Inc. specializes in design/build construction, making us a one-stop shop for all of our customers’ building needs. Design/build is the most effective way to build high quality buildings, combining form, function, and cost effectiveness without sacrificing quality.

In tandem with our design/build capabilities, we specialize in using value engineering, which helps minimize building cost, and maximize return for our customers. Value-engineering effectively balances the cost of materials and the form and function of those materials. This is a highly beneficial method of commercial building that maintains both cost control and quality.

Along with value-engineering giving our clients the greatest return on their investment, A.B. Systems, Inc. is developing expertise in Green Building and LEED certification. Our goal is to continue providing customers with the greatest quality possible while improving energy efficiency and material costs.

A.B. Systems, Inc. produces a quality structure that is on-time, fair-priced, functional, appealing, and matches our customers’ expectations.  We’ve built our business on quality, and demand that our management, employees, suppliers, and sub-contractors do the same.
