Engineering & Environmental Studies

The Project Approval/Environmental Document phase of work requires a number of technical studies to be completed. Engineering studies include traffic volumes, mapping, public utilities, geotechnical reports, materials reports, drainage and storm water reports, and right of way needs. The results of these studies are used to develop cost estimates and prepare for future phases of the project – final design, right of way acquisition and construction.
