Value Engineering, serving as a sub-consultant, will provide complex roadway design services for the M-39 freeway and associated ramps within Detroit and Dearborn, specifically from Cathedral St to Tireman Rd. M-39 (Southfield Freeway), originally constructed in the 1960s, spans through Detroit and Dearborn. This includes developing a comprehensive 3-D model for alignments, profiles, unique templates, and tie-ins at ramp terminal intersections, among other detailed design aspects.
This project entails a comprehensive 4R reconstruction of the M-39 freeway and all ramps within the specified limits, excluding the I-96 interchange. Key components of the project include:
Complete removal and replacement of mainline and ramp pavements.
Installation of single-face concrete median barriers.
Modification or replacement of service road screening walls.
Upgrading storm sewer systems with oversized dual trunk lines.
Analysis and upgrade of pump stations.
Replacement of raised outside shoulders with flush shoulders.
Installation of freeway lighting, signing, permanent pavement marking, landscaping, and other associated works.
Signal work at ramp terminal intersections is not within the scope.
SCOPE OF WORK: As a sub-consultant under AECOM, VE's responsibilities include:
Detailed roadway design from Cathedral St to Tireman Rd.
Development of a 3-D model incorporating alignments, profiles, unique templates, and tie-ins.
