Calvin, Giordano & Associates, Inc. (CGA) provided the Construction, Engineering and Inspection (CEI) services on I-95 rigid pavement replacement and emergency stopping sites (ESS) construction design-build contract in District Six.
The project included the removal and reconstruction of all rigid pavement on I-95 from north of NW 29th Street to north of 79th street, the removal of existing asphalt shoulders within the project limits, replacement of the existing asphalt shoulders with 10.5” thick concrete rigid pavement, milling and resurfacing of entrance and exit ramps between NW 29th street and NW 79th street, replacement of the existing guardrail within the project limits to meet the latest standards, replacement of five (5) existing bridge traffic railings; to meet the latest standards and crash testing requirements, reconstruction of bridge approach slabs on 22 bridges, minor signalization improvements at the ramps, replacement of existing express lanes delineators, upgrading the Intelligent Transportation System (ITS) cameras and poles, and signing and pavement markings improvements.
The project also included the construction of 13’-4” Express Lanes Emergency Stopping Sites at 5 locations (2 in the SB direction and 3 in the NB direction) from NW 62nd St. to NW 131st St. The construction of the stopping sites will be accomplished by removing the existing concrete median barrier wall and concrete pavement, then widening the adjacent slab by 5’-5”. This involved the removal and replacement of existing drainage structures, the installation of new shoulder inlets with 15” drainage pipe in the median to address ponding issues at the 5 ESS Sites.
CGA was responsible for the maintenance of the roadway, the impacted ramps, and frontage roads. This maintenance will include but is not limited to, delineator replacement, incident management, lighting, landscape, pothole repairs, and ITS maintenance from the time the existing ITS equipment is switched with the new equipment. The ESS Sites are substantially complete and are open to the public.
