Bath Iron Works - Land Level Transfer Facility - Precast Concrete Solutions for the Open Deck Platform

A world-class shipyard is being constructed in Bath, Maine. This major facility modernization of the Bath Iron Works is known as the Land Level Transfer Facility, and includes a 6-hectare (15-acre) land level platform for ship assembly, as well as a 230-meter (750-foot) floating dry dock for ship launch and retrieval. The platform structure is comprised of two distinct components: a retained-fill structure and a pile-supported open deck platform. The pile-supported deck has been designed and constructed primarily of precast concrete components, the choice of which has enabled the contractor to adhere to an aggressive schedule despite an equally aggressive environment. The project, a design/build effort between Clark Construction and Moffatt & Nichol Engineers, with BERGER/ABAM Engineers Inc. as an engineering subconsultant, is an excellent example of how the design team can work very closely with the contractor to create precast concrete solutions that are tailored to specific site conditions and schedule requirements. More importantly, these innovative solutions are provided to the contractor while at the same time giving the owner a durable and serviceable design that meets the demanding requirements of the shipbuilding industry as well as the environment.
