Pretek Group is a leading designer and developer of precast concrete elements and systems used in transportation infrastructure projects, specializing in buried bridges and culverts. From preliminary design through construction, we work with engineers, precast concrete producers, contractors and owners at each step along the way.


Pretek Group was founded in 2009 to provide specialized engineering expertise for precast concrete buried bridges.  Soon after, the firm introduced the ECO-SPAN® Arch System brand name.  Similar designs for 3-sided and 4-sided concrete box culvert systems are also available.

In addition to engineering and design services, Pretek Group offers technical marketing and training, specialized form rental, and field support during installation.

In the firm’s first decade, we have been involved in hundreds of successful fast-paced projects involving prefabricated elements and systems for highway projects throughout the United States.  We have a proven track record of delivering excellent results on tight schedules.
