Are you ready for Colorado’s new Digital As-Constructed Requirements?

By Nate Osterberg, Pipeline Inspector, WSB

Effective January 14, 2021, the Colorado Department of Transportation (CDOT) will mandate that all new permitted utility installations meet Digital As-Constructed Requirements (DAC) in accordance with the Utility Accommodation Code Rule 3.3.4.6.2.  New requirements under State Highway Accommodation Code, 2 CCR 601-18, Rule 3.3.4.6.2 Digital As-Constructed Requirements, Plan and Profile 3.3.4.3 mandate uniformity in utility mapping, as-builts and plan-and-profile submissions. Utility permits will begin stipulating this requirement soon.  Additionally, there are new Plan and Profile requirements for all Horizontal Directional Drilling (HDD) operations within CDOT’s Right of Way.

But what does this mean?

Essentially, this means that anyone working within CDOT’s Right of Way must perform a digital utility locate survey for any underground utilities – commonly known as Subsurface Utility Engineering (SUE).  The survey must be submitted using their chosen software. 

What is SUE?

SUE is an engineering practice used to obtain reliable underground utility information. Accurate and successful SUE practices benefit contractors, transportation departments and utility companies by limited the need for unnecessary utility relocations, avoiding unexpected conflicts and enhancing safety.

How do I do this digitally?

You combine the right tools with the right expertise. The digital world of 3D modeling can be intimidating, but a digital approach is actually more accurate, efficient and safe. Using mobile mapping software, utilities can be captured, recorded and displayed precisely accurately and seamlessly.
