Dry Dock No. 1, originally constructed in the early 1830s, is a smaller size dry dock currently used for docking the USS CONSTITUTION for maintenance and repair. The dock is considered a sister dock to that of Dry Dock No. 1 located in Norfolk, Virginia.
In 2013, HEGER was part of a teaming arrangement hired to modernize and improve the facility which included designing and building a replacement caisson gate.
As part of the project, HEGER was responsible for naval architecture aspects of the new steel floating gate design including stability and draft requirements. HEGER assisted in the development of projects drawings, calculations, and specification.
The new gate was constructed by STEEL AMERICAN in Norfolk, Virginia and delivered to Boston, Massachusetts where it continues to operate successfully.
