The 1,400-acre Luther Forest Technology Campus in Malta, New York, is the
future home to the most advanced semiconductor manufacturing facility
in the world. The goal of this $35 million project was to design and build
transportation infrastructure connecting the campus to existing state highways
and local roads. It included 5.5 miles of multilane roads, 7.5 miles of trails,
several culverts, and a stormwater system.
For the 1 million cubic yards of earthwork, Creighton Manning Engineering
developed 3D digital terrain models, which were instrumental in analyzing
alternative alignments to avoid impacts to wetlands and archeology sites. The
3D data and InRoads ALG files were provided to the contractor to expedite
construction. The integration improved productivity and accuracy. Using
stakeless survey also saved $500,000 in surveying fees.
Construction of an Auxiliary Passing Lane
La Tuque, Canada
Highway 155 is a thoroughfare linking the Mauricie and Lac-Saint-Jean regions
in Quebec. However, the lack of a passing lane for heavy vehicles, which
constitute up to 30 percent of traffic, resulted in an unacceptably high accident
rate. Dessau was retained to create an auxiliary passing lane, which involved
determining the optimal position in a mountainous wetlands area.
MicroStation and InRoads enabled Dessau to consider several route possibilities
and profiles, despite the short time frame allocated for design. Several
simulations were completed to find the ideal geometry, with 3D simulations,
volume measurements, and verification of right-of-ways generated for each
scenario. Valued at $5.5 million, the auxiliary lane is currently under construction.
