Brayman Construction Corporation - North Shore Connector – Miller Printing - Pittsburgh, PA - 2009 - $200,000

Scope of Work:
Neumeyer Environmental was contracted to provide environmental management and construction support services for a subway connector tunnel beneath the Allegheny River from downtown Pittsburgh to the North Shore area. The terminal end of the tunnel included a station to be constructed on a parcel that previously housed a print factory in a previously industrialized area of the city. The site is located between the Rivers Casino and Heinz Field. Neumeyer Environmentals’ scope of work included performing the construction surveys, sampling and analysis of potentially impacted subsoils, and management of contaminated materials.

The parcels within the zone of influence of vibration-inducing activities included Heinz Field and several other structures currently in use. Neumeyer Environmental performed the surveys and installed multiple monitors within the structures so the prime contractor could evaluate potential structure movements during select work activities. When the construction is complete in 2010, Neumeyer Environmental will perform the post-construction surveys to provide a record of the structural condition after the work.

Neumeyer Environmental performed sampling and analysis of the excavation materials to determine if the materials classified as clean fill or required special management. Several areas of the site exhibited contamination that required off-site management. This pre-classification of the materials allowed the prime contractor to better stage the materials during the work.
