• Description:
  The greatest barrier to using 3D digital design data in highway construction is ineffectively managed uncertainty regarding whether the constraints assumed in design reflect actual field conditions. Verifying the original ground close to construction is an effective, digital preconstruction quality control method to avoid basic construction issues. Usually, resident engineers lack a facility to manipulate 3D data confidently; contractors have comparatively advanced expertise with 3D data. Construction partnering is a viable solution to collaboratively use 3D data to save time, improve transparency, and build confidence in 3D data uses. Inspectors can use 3D data that represents the design intent with field survey equipment for real-time verification and to measure quantities. This is a safe and efficient e-Construction practice.
