Solids and Parameter Modeling

2000-2001: Solids & Parameter Modeling *New York, NY*
The Metropolitan Transit Authority has begun a ten-year, $6 billion expansion project that will connect two existing underground train lines via new cut-and-cover and bored tunnel operations. (see map). Through the development and application of sophisticated 3D geologic and parameter models, Hazlett-Kincaid will be working with a joint venture of a large transportation engineering firm and an environmental group to optimize characterization and excavation strategies and minimize environmental costs.
						LNAPL - near proposed cut & cover construction
						In later stages of the project, groundwater flow and contaminant transport models will also be developed in order to quantify the impacts of the tunneling and cut-and-cover operations on existing and future subsurface conditions.


Above - 3-D solids and parameter model of the site in Long Island (site map shown in above left). Model depicts the 3-D distribution of hydraulic conductivity above the bedrock surface and the orientation of proposed tunnels and cut and cover excavations.
