Braddock Lock and Dam - Monongahela River
Survey for Braddock Lock
Client: J.A. Jones / Traylor Bros.
Location: Braddock and Leetsdale, Allegheny County, PA

LSSE provided high level control / baseline surveys for construction of the Braddock, PA lock and dam on the Monongahela River including critical control for the setting of caissons and subsequent fitting of the prefabricated dam components. LSSE also provided control surveys for the fabrication of dam components at the Leetsdale, PA fabrication / casting cell as shown in the images.

LSSE's survey crew was on site during all phases of fabrication in the remote Leetsdale casting facility (20 miles from dam location), river transportation and construction for this 'first of its kind' (USA) dam construction project.
