A Suite of Design Tools that Works for You

No matter the project—be it stormwater detention, infiltration, sanitary sewer, or bridge design—the Contech Design Center streamlines the engineering workflow by enabling faster development of project-specific drawings, engineering calculations, and BIM/CAD files. It also facilitates close collaboration with Contech’s engineering team. This approach shortens design timelines, supports compliance with regulations, and enhances constructability, resulting in more efficient, cost-effective, and dependable project execution.

This tool allows you to design a Big R Rolled Girder bridge based on your site's specific parameters. Customize key features such as finishes, wearing surface, sidewalks, utility support, and more.
Log In and Use the Tool

This tool streamlines the layout process for stormwater detention and infiltration systems, optimizing designs to meet storage requirements or maximize storage within a given footprint. It supports system configurations using Corrugated Metal Pipe (CMP), ChamberMaxx® plastic chambers, and DuroMaxx® Steel Reinforced Polyethylene (SRPE), giving you flexibility to match your project needs. You can also import site plans and create multiple systems for each project while saving all project information for future use.
Log In and Use the Tool

This tool helps you identify the optimal hydrodynamic separator for your site. It offers multiple sizing methods, and site-specific questions ensure the selected unit meets all relevant constraints. The generated report includes a site-specific design, sizing summary, standard detail, and specification sheet—providing everything you need for confident design and documentation.
Log In and Use the Tool

This tool helps assess whether relining an existing culvert or drainage system is a viable option for your project. By entering a few key project details, you’ll receive a general evaluation of your site along with potential reline solutions to consider. Each recommendation includes supporting documentation tailored to the parameters you provide.
