In order to design these upgrades in the most efficient manner, LandTech Consultants was retained to provide full documentation of the existing conditions utilizing terrestrial laser scanners. LandTech then utilized the resultant point cloud to develop a 3D existing conditions BIM model with precise locations of all relevant structures, systems, and equipment, including wet wells below grade. By documenting the existing conditions prior to improvements in design, the team was assured of minimizing potential design conflicts with the existing infrastructure that could result in costly change orders during construction.
