HBK Engineering was responsible for the design of approximately 3200 linear feet of 9-6” PVC conduit package from Noble-Kinzie Terminal to Goose Island Terminal, including the installation of two new transmission manholes, one transmission manhole expansion, and one manhole roof replacement. HBK developed a 3D model of existing utilities along the project route from utility atlas information, field measured utility invert information, and manhole scans in order to perform the civil underground design. HBK was responsible for test hole plans, restoration plans, traffic control plans, and cable pulling calculations. HBK designed earth retention systems for trench shoring including deep excavation trenches, manhole shaft shoring, box tunnel shoring, reinforced duct package for railroad crossing, and several utility supports. To secure permits, HBK worked with the Chicago Department of Transportation. In addition to design phase activities, HBK provided construction support and record survey to develop as-built drawings upon completion of construction. As-built drawings were developed in CAD and brought into GIS to update ComEd’s database.
