Alpha & Omega Group provided project management, civil, structural, and water resources engineering and construction administration for the design of new sidewalk infill and a new pedestrian bridge linking sidewalks along SW Cary Parkway.

A&O managed utility relocation and coordination, placement of fill and fine grading, erosion control, upgrade of an existing ADA ramp, installation of an additional ADA ramp, improvement of an existing pedestrian at-grade crossing, FEMA flood study, traffic control design, and construction administration. The pedestrian bridge was placed so that it would completely span the floodway above the 100-year base flood elevation and not cause an increase in the base flood elevation, so a “no-rise” could be achieved. We arranged permitting from local, state and federal agencies. Our team identified and delineated wetlands and incorporated them in the construction plans. The pedestrian bridge was set overnight to reduce inconvenience to the public. A&O provided construction administration services to complete the project for the Town of Cary.

Under A&O’s project management, SEPI provided environmental and traffic control services. GeoTechnologies, Inc., provided subsurface investigations, foundation recommendations for the walkway and bridge, and materials testing for the construction phase.
