Port of Ellsworth Berth 4 Terminal Improvements

Rehabilitation of 600 linear feet of berth, new crane rail, upland paving, stormwater treatment and utility upgrades for a working cargo terminal.

The challenge

What made it hard.

The port stayed in operation throughout. Tidal windows controlled marine work, sediment testing found localized contamination, and the project had to satisfy federal grant reporting alongside the construction schedule.

The solution

How we built it.

Marine work was planned around the tide and vessel schedule, with the berth closed in defined windows and cargo operations relocated to adjacent berths. Contaminated sediment was dredged, segregated and disposed of under an approved plan.

Upland work was sequenced so trucks could keep using the terminal, and a monthly funding report was produced alongside the normal progress documentation.

The outcome

Where it landed.

The berth reopened on schedule with a 40-year design life and a stormwater system that meets the port's current permit. The port has since awarded Craneway Civil Construction the adjacent berth 3 improvements.

Their field crew caught a conflict in the drawings that would have cost us a month of marine work. They brought a solution, not a change order.
