- Survey coordination, design review, cost estimates, drawings and technical reports
- Project management support, stakeholder coordination and QA/QC input
Site investigation and disturbed soil sample collection
Trial pits, in-situ dynamic cone penetrometer (DCP) testing and disturbed soil sampling along the alignment provided the subgrade and borrow material data for the road design.
