utilizing geophysical equipment to horizontally position the subsurface utilities (Quality Level B), subsurface structure reviews/diagrams, Utility Coordination, and full CAD drawings for the transit project . In addition, the CMAR team lead originally requested more than 4,000 Quality Level A test holes based on project size. Once the utility mapping was complete, the design team was able to update and optimize the de- sign using the high-quality mapping Cardno provided and reduced the number of holes by more than 2,800, saving approximately $2.5 million in reduced test hole, traffic control and pavement restoration fees. GHD City of Cambridge Hespeler Tr unk Sanitar y Sewer Project Working with the City of Cam- bridge, GHD rehabilitated the Hespel - er Trunk Sanitary Sewer. The project consisted of the structural rehabili- tation of 4,500 ft of large diameter sewer. GHD provided a full range of services from condition assessment to oversight and warranty. Some of the highlight include: • The sewer system was improved to a Grade 1; • The CIPP method reduced the schedule and capital expenditure; • GHG carbon emissions calculator showed a reduction of 790 tons were eliminated; • Achieved 8-10 percent reduction in infiltration; and • The project was completed on- time and under budget and was awarded 2018 Project of the Year from the Centre for Advancement of Trench- less Technologies (CATT). KCI Technologies SUE Mapping in Corpus Christi, Texas The KCI team provided subsurface utility engineering , research and GIS coordination to map more than 570,000 lf of utilities in support of the design-build contract to replace the SH-181 Harbor Bridge in Corpus Christi , Texas. The $900 million proj- ect involves construction of a new cable- stayed crossing with a 1,661-ft- long main span and 6.5 miles of ap - proach and connecting roadway. The congested corridor included miles of water, wastewater, oil and gas, elec- tric, telecommunications and fiber optic infrastructure that required lo - cating , engineering review and/or re- location design services. KCI 's incred- ible team provided Quality Levels A-D locating and excavation, devel - opment of a detailed conflict matrix , and subsequent utility coordination and relocation design required for this mega-project .
