Lockport Pool Major Rehab | Illinois

City: Lockport
State: Illinois
Owner: U.S. Army Corps of Engineers
General Contractor: ASI Constructors

Project Description:
The existing canal wall was starting to crumble, which led to a section of it being replaced with Roller Compacted Concrete (RCC). This new section was offset from the original canal, and two secant pile cutoff walls were designed to connect the new section to the existing section. These secant piles were socketed into rock and overlapped the new RCC and existing canal wall in order to make the transition.

Project Relevancy:
A series of overlapping secant piles were installed through the existing rock fill and overburden, and socketed up
to 11’ into the Dolomite bedrock. Verticality was measured on every secant pile installed. Difficult access and site
constraints were overcome with proper sequencing and scheduling of different equipment and operations.
