Maxymillian effectively removed 12,000 cubic yards of MGP contaminated soils and sediments from 5 riverbed areas of the Green River in Greenfield, MA.  Maxymillian installed two separate 800 linear foot Portadams in the Green River to divert flow and allow excavation in the dry, installed a tie-back system to support a 300 LF cutoff wall during excavation, installed a temp 40 FT span Mabey Bridge in 1 day, performed high volume excavation and Cement Kiln Dust (CKD) stabilization, prior off-site disposal, and backfill. Low odor threshold required extensive odor and dust control measures throughout the project.
