The $52 million proposed State Route 35 widening corridor is located on Sand
Mountain, east of the Tennessee River in Alabama. The project scope is to
complete a remaining four-lane, 4.2-mile segment. The Alabama Department of
Transportation (ALDO T) evaluated alternatives to identify a scenario that could
be carried to final design. The final design requires a 12-foot cut into the existing
mountainside to accommodate the additional lanes.
ALDOT used MicroStation and InRoads to provide a better understanding of the
project to internal decision makers and sell the project to the public. Using these
solutions will not only minimize earthwork alongside slopes, thereby preserving
existing property lines and maintaining ongoing relationships with landowners,
they will also reduce project costs. During construction, ALDOT will also protect
the Ferncliff Gap cave habitat of myotis bats.
Eglinton Crosstown Light Rail Transit
The $2.8 million Eglinton Crosstown light rail transit project will introduce fast,
high-volume public transit subways to a large region of Toronto, Canada. With
existing subway lines crossing Eglinton, the new route will tie in effectively
with those systems to provide efficient transportation. Coffey Geotechnics
was retained by the Toronto Transit Commission to complete a geotechnical
investigation for the Eglinton Crosstown light rail transit project.
Coffey found Excel tables and other CAD programs limiting. So working with
Bentley, Coffey completely redesigned its gINT database as a component-based
structure so it could handle log formatting, perform powerful data mining and
filtering tasks, and execute basic calculations. This led to standardized borehole
layouts, geotechnical cross sections, and other smart fence diagrams, which
greatly enhanced information for decision making and planning.
