Charlotte, NC

CALYX had previously provided subsurface utility engineering services on time and on budget for the CATS South Corridor Light Rail, so when it came time to construct the Northeast Corridor Light Rail, and complete the Blue Line, CATS and STV once again called on us. The Northeast rail runs along a nine-mile corridor from Ninth Street in Center City to the University of North Carolina at Charlotte campus. The LYNX Blue Line Extension is a comprehensive transportation system that includes roads, buses, bus rapid transit, and commuter rail that provides an alternative to drivers facing traffic congestion on I-85.

CALYX provided topographical and traditional surveys for over 750 properties and 1,500 storm and sanitary sewer structures along the proposed Northeast commuter rapid transit route. In addition, the team provided Quality Level A and B utility designation and subsurface location of domestic water lines, high voltage power cables, telephone conduit, traffic monitoring cables, long-distance communication fibers, fiber optic telecommunication cables, and gas mains. In all, we designated and mapped over 1.7 million LF of utilities and completed over 300 Quality Level A vacuum excavation test holes to assist design engineers in minimizing any potential utility conflicts prior to construction.

All work was completed in accordance with City of Charlotte’s Transportation Plan on time and on budget.
