We hit a big milestone! H.B. Fleming — one of our major subcontractors on the Back Cove South Storage Facility Design-Build Project in Portland, Maine — has started to drive sheets for our phase 1 sheet pile cofferdam!
Once the interior is excavated, the cofferdam will be approximately 510’ long, 70’ wide, and 30’ deep. A mirror-image cofferdam will be constructed for phase 2 in 2021.
