Tunneling and Subway Assessment

Earthfx Inc. has done work in the tunneling and subway assessment which is because of our expertise in creating advanced computer models of watersheds. It includes working to provide assessments on future sewer or subway tunnels for example. This is a field that our company is looking to expand due to our growing expertise and better understanding of what is needed.  See some of the projects we have done below.

Southeast Collector Sewer Environmental Assessments

Southeast Collector Sewer Environmental Assessments

Earthfx developed a 3-dimensional groundwater flow model to analyze the impacts of construction dewatering for the Southeast Collector (SEC) Trunk Sewer on groundwater and stream baseflow.  The work was done in support of the Hydrogeological/Geotechnical Southeast Collector Trunk Sewer Environmental Assessment.  This study followed an earlier modelling analysis for route selection, also completed by Earthfx.
