Port Expansion of Eastport, Maine

by Ronald R. Bourne, Childs Engineering Corp, Medfield, MA, USA,



Document Type: Proceeding Paper

Part of: Ports '86

Abstract:

A recent pier expansion now allows Eastport to provide 40 feet of water at low tide. The pier expansion consists of a concrete-decked steel pipe pile-supported extension to an existing L-shaped breakwater. Unique factors of this project included dealing with a 40-foot draft plus a tidal difference of up to 26 feet. Requirements included limiting the construction period to 120 days to curtail the economic impact on Eastport. To achieve this, the contractor utilized a composite deck using precast deck planks as the bottom form and a cast-in-place topping. The contractor also was able to precast the concrete pile caps thereby saving time by minimizing the amount of over water formwork.
