CDG is a Gold Standard Pledge Partner of MoDOT's " Buckle Up Phone Down" movement? This program challenges drivers to stay off their cellphones when behind the wheel. We are doing our part to Arrive Alive, are you?

As engineers, we are always looking for better tools to enable a more efficient design process to create a better product. Through the use of virtual reality (VR), we allow immersive explorations of designs and instant conceptualizations of drawing. In fact, our use of VR technology, 3D modeling and Revit allows us to present a design to the client and walk them through the project site in real time. In doing this, we have seen nearly 30% of the project completed in just 1 day.

For more information on our Design Technology services, including VR, AR, 3D modeling and more, reach out to Lyle Hardin.

In September of 2017, CDG was contracted by MoDOT to design a bridge replacement along eastbound I-44 over Pickerel Creek, just west of Springfield, Missouri. MoDOT estimated that the 50+ year old westbound bridge still had 10 years of remaining service life, and consequently, this bridge would be used for one-lane head-to-head traffic during construction of the new eastbound bridge. However, through the use of traffic models, it was determined detouring traffic this way could result in daily traffic delays of up to 20 miles, or 18,000+ vehicles backed up in each direction!

CDG worked closely with MoDOT to design an alternative staged construction solution for the eastbound bridge replacement so that the two lanes of the westbound I-44 bridge could remain in use for westbound traffic only.

CDG designed a wider replacement for the eastbound bridge to be constructed in two phases so that at least one 13-foot lane would be open to traffic at all times during construction. The first construction phase began in August of 2018 with both stages scheduled to be completed in December of this year. This design solution has caused minimal daily traffic delays to the traveling public.
