The Leighton Solution.
Working for the lead civil engineering firm, Leighton provided a Phase I Environmental Assessment, Aerial Deposited Lead survey, Geotechnical Data Report (GDR), and a Geotechnical Interpretive Report (GIR) with design information for the pipeline, backfill, tunnel lining, shoring, dewatering, seismic design parameters, and settlement potential.
We also prepared a Geotechnical Baseline Report presenting the baseline conditions for bidding by the contractors and reference during construction.
