Project Highlights

T2 Utility Engineers completed a Subsurface Utility Engineering (SUE) Investigation on Front Street for the Union Station Expansion Project. The investigation was completed in several phases. The first phase was a field investigation focused on designating the horizontal location of the utilities in the area, followed by three rounds of test holes. The investigation was successful in confirming and further refining the location of the existing utilities, as well as identifying some features that were not shown on the existing record drawings. Inverts and other verification of sewers were made at key locations where additional information was required.
