Black Creek Greenway
In 2001, the Town of Cary began developing a 4-mile greenway system to link to schools, parks and neighborhoods. Segment 3-Phase II consisted of a 10-foot wide multi-use trail approximately 1.3 miles in length and three bridges. One of the bridges is a 200-foot clear-span pedestrian bridge over a Conrail Rail Line. In addition, the project involved the construction of four mechanically stabilized earth retaining walls and installation of deep pile foundations.
Geotechnical Engineering Services
S&ME performed verification tests to verify the compressive strength and air content of concrete in bridge abutment walls and footings. S&ME also performed grading of the trail alignment, subgrade stabilization, and embankment fill placements. In-place density tests were performed to evaluate the compaction of approximately 8,000 cubic yards of embankment fill already in-place. S&ME reviewed information pertaining to the method used to stabilize soft wet subgrade conditions encountered during construction of the greenway trail.
Construction Engineering Inspection and Construction Materials Testing Services
As construction moved forward, S&ME provided engineering technicians with appropriate NCDOT certifications in the services provided to performed subgrade evaluations and soil compaction testing, stone base course sampling & testing including stone thickness and cross-slope checks, observation and testing of segmental retaining walls, sampling and testing of concrete and asphalt pavements, and structural steel inspection of the clear-span bridge.
