More and more projects are being generated in 3d but Principle Design Group realizes that too many times the 3d models from various disciplines and or vendors are not coordinated for interferences. This leaves a large gap between the various 3d models and the 2d installation drawings which will yield a multitude of field issues upon installation. Robust 3d model coordination prior to installation will flush out the majority of field interferences resulting in cost savings to the owner and or contractor.
