Client: Regional Public Transportation Authority Location: Phoenix, AZ Value: $1 Billion (Construction)
Our firm performed conceptual and preliminary rail engineering
support for the proposed 20-mile Central Phoenix/East Valley
Light Rail System. In support of the final environmental impact
statement (FEIS), we were responsible for evaluating several
LRT alignment and profile alternatives; technical narratives;
shop and yard location studies including development of several
conceptual storage yard layouts for the preferred sites; evaluating
types of embedded and cover track; and assisting in the resolution
of technical issues relating to Union Pacific Railroad right-of-way
and railroad/LRT operations. During the Preliminary Engineering
Phase, we were responsible for the development of preliminary
engineering plans and specifications for the entire 20-mile proposed
light rail system including the LRV maintenance shop and yard,
operations control center, and maintenance-of-way complex. Responsibilities
included trackwork design and standards; roadway, track, and
platform typical designs and sections; platform clearance criteria;
and roadway/LRT alignment interaction studies. Our duties included
providing architectural support and identifying right-of-way
needs and preparing supporting documents for ROW acquisition
during the preliminary engineering phase.
In addition, we are developing the final communication design
and specifications for:
SONET-based Fiber Optic Network
ADA compliant VMS and PA systems and CCTV systems
for both the Yard and 28 stations
EPABX with remote modules to support the Maintenance
Facility, OCC, and Passenger Assist Phones at the stations.
Services Provided:
Developed a conceptual equipment list, proposed
maintenance/operating costs and projected number of workers
and parking requirements for maintenance shop and yard facilities.
Conducted a site selection evaluation of 14 LRV
maintenance shop, MOW support and storage yard sites to accommodate
a fleet of 100 low-floor articulated LRVs, and developed a
conceptual-level cost estimate for the maintenance shop and
yard complex.
