Harbor Towers

Architect Stephan Nousiopolous

Project Cost $16 million

Address New London, CT

e2 brought its expertise mid-project to this new construction, nine-story residential tower located in the heart of historic, downtown New London. The structure consists of three floors of cast-in-place concrete, two-way slabs. Upper stories are structural steel framing with composite floor slabs.

THE CHALLENGE

In 2007, e2 engineers was commissioned to design a new eight-story residential project located here in New London. The project site is located in an area where poor soil conditions dictated that the structure be supported on end-bearing structural steel H-piles. Construction began and soon thereafter the economy took a turn for the worse, resulting in the project stopping for several months after the third floor parking deck structure had been constructed.

The project was resurrected with new ownership that had a specific demand in order for the project to resume; a ninth floor for penthouses was required to make the project solvent. e2 engineers was charged with performing an analysis on the previously constructed structural systems, including foundations, to determine if adding a ninth floor was feasible.
