Our skill and experience stretches across the spectrum of all building types, whether it be steel, wood, concrete, masonry, precast, or pre-engineered buildings. 


Thomas Design Builders offers innovative Design Build solutions to our customers.

Design Build project delivery provides single source responsibility for our customers. In that, both the design and construction of your project is supplied by one company, under one contract, for one guaranteed price. Our team of design professionals, engineers and drafting personnel, combined with our experienced on-site supervisors and reputable sub-trades, delivers a completed project that we, and our customers, can be proud of. 

As a fully seasoned “Design Builder”, TDB has in house Designers and experienced, qualified Project Managers, ready to discuss your turnkey build. 

We take your project, with the parameters provided, from concept to designs, to completion!


The Design and Construction Management concept offers our customers the opportunity for hands on involvement with our team in order to provide the greatest flexibility in design and budget decisions, throughout the project. This hybrid approach between “Design Build” and “Construction Management” is our most preferred construction approach; and 98 percent of our customers choose this procurement strategy. 

This unique process allows our customers to procure their construction needs, with a gradual, pay as you go process to complete conceptual design and ultimately construct their facility with the pure flexibility of their involvement in design and construction.  This process is transparent, cost plus approach, with a guaranteed maximum price sharing risk and provides the best value possible.


Good pricing to us, means the best price for our customer. 

For the project that requires the traditional method of delivery where plans and specifications have been prepared by others, Thomas Design Builders is well positioned to provide very competitive tender bids. Our experienced construction personnel as well as our reputation for well-run, efficient projects provides us with the best material and subcontractor pricing in the industry. 


As Construction Managers, we assist in the selection of both technical and industry professionals. Thomas Design Builders prepares initial budgets and provides continuous budget updates throughout the design phase. We coordinate drawings while providing plan revisions, cost savings and budget control. We tender all work to sub-trades, provide contract administration with our fully integrated cost accounting systems, and coordinate all site activities to ensure that the project finishes on budget and on time.


Consider the cost advantages of a National Energy Code compliant Pre-Engineered Building System for your next project. Thomas Design Builders has been an authorized builder and supplier with Robertson Building Systems since 1988; now backed by the world’s largest pre-engineered supplier. 

We have received numerous awards for ‘Builder of the Year’ in the Mid-West Region and ‘Best Of’ in building categories for design and construction innovations.

Pre-Engineered Buildings have evolved to be more than just steel boxes- like structures featuring large spans, and inverted flat roof and building cosmetic far outreaching conventional construction prowess.
