Stolfus at 2018 Training for Transportation and Environmental Professionals

Members of the Stolfus team recently attended the 2018 Training for Colorado Transportation and Environmental Professionals, lead by the American Council of Engineering Companies of Colorado (ACEC), along with Colorado Department of Transportation (CDOT) and the Colorado Contractors Association (CCA). This yearly training event provides Colorado-wide industry policy updates, best practices, and lessons learned from the past year.

Curb ramps were a popular topic during this year’s training. CDOT has been working through their Curb Ramp Prioritization Plan, and several municipalities have been sharing their best practices and lessons learned with CDOT along the way. The City and County of Denver held a breakout session with CDOT and shared the following tips:

  • The City and County of Denver has been doing most of their curb ramp projects by just showing a location and anticipated type of curb ramp. No layouts are being done. This could be useful to apply on other projects where the terrain is fairly flat, and the curb ramp standards can be applied fairly easily.
  • Inlaid striping removal on concrete roadways to remove crosswalks for relocation have been creating ponding issues where the old striping was. This tends to freeze up and become icy for vehicles and pedestrians. CDOT wants to find a solution to this.
  • City and County of Denver has recently changed their design specifications for curb ramps so that they are not designed to the maximum slope allowed. They give tolerances in their standards, but the 8.33% ramp slope is a firm requirement with no tolerance. A good practice is to check the tolerances of curb ramp slopes in a municipality you are working in.

Utility break-out sessions were also popular during this year’s training, given the upcoming changes involving responsibility of utility information for roadway projects. CDOT shared several of the upcoming utility changes:

  • CDOT has a new workflow for utilities during the design. More information will be required about utilities at 30% design.
  • An interactive web tool is coming to CDOT that will host utility information that is being gathered.
  • Existing utility information will be a larger focus during the NEPA process.
  • There are different quality levels for utility information. Most traditional roadway proejcts will be required to supply Quality Level B (QLB) utility information. This will require survey of existing utilities for location and depth, and will need to be sealed by a Professional Land Surveyor (PLS).
  • A subsurface CAD manual will be released by CDOT that will have new standards on how and when utilities are shown on plan sets.
  • Complicated utility projects will often have a “Utility Preconstruction Meeting”.

We look forward to incorporating the information gathered from the training on future projects throughout the state.
