DB Sterlin performed construction inspection services including the documentation of daily construction activities and assurance that the Contractor’s work complied with contract plans and specifications.

The project was a 2.7-mile-long elevated linear park and trail running through the heart of Chicago, connecting neighborhoods, the river, and Chicago’s great park system constructed on an unused elevated rail line embankment along Bloomingdale Avenue. The new trail and park space provided new elevated open green space separated from vehicular traffic and highlighted the connection to the natural elements already present along the top of the trail. The project converted the existing 2.7 miles of the elevated rail line and embankments along Bloomingdale Avenue between Ridgeway Avenue and Ashland Avenue to a series of grade-separated parks and a multi-use trail for both pedestrians and bicyclists all set within a new landscape creating diverse and dense ecological areas. The project involved the rehabilitation of thirty-seven elevated and embankment segments, construction of thirteen ADA-accessible access points, and six new parks.
