PB providing CM services for CTA Blue Line

Written by admin

The Chicago Transit Authority has awarded a construction management contract to Parsons Brinckerhoff for a rail replacement and tunnel rehabilitation project on the system's Blue Line subway, which connects the downtown business district with O'Hare International Airport.

The
$88-million project is one of the first in Chicago to be fully funded by the
American Recovery and Reinvestment Act of 2009. It involves replacement of
31,000 existing wooden half ties with new concrete half ties and 6,200 track
feet of stone ballast with new concrete slab and direct fixation
fasteners.  The project also
includes the installation of 29,000 track feet of new rail and the installation
of 44,000 linear feet of new contact rail. Additionally, two track crossovers
will be rebuilt, all lighting and drainage systems along the route will be
cleaned and some structural repairs will be performed in the four-mile-long
Dearborn Blue Line subway tunnel.

As
the construction manager, PB is responsible for schedule and cost control and
quality/safety assurance, as well as construction supervision, inspection and
documentation.
