Our Goal
LJA’s mission was to perform the construction phase project management and inspection of this multi-year sewer replacement project on CSX right-of-way (ROW). The project included the placement of manholes, cured in place pipe (CIPP) rehabilitation, waterline, and a 60-inch micro tunnel under a busy, double main line. LJA coordinated flagging, signal locates, and FCI services and reviewed all construction phase submittals.
The LJA Roadmap
The LJA roadmap included management of the pre-cons for both phases and coordinated flagging/FCI throughout the two-year duration. Our team worked closely with the track supervisor to determine the best use of resources in a busy region, collaborating with the local signals manager to coordinate signal locates and Inductive Interference Studies.
Notable issues management solutions include:
• Work was near a tank car facility yard. During construction, an unmarked underground sewer was struck LJA assisted with mitigation efforts and coordination with the yard.
• Existing drainage structures made design changes necessary. LJA promptly reviewed the design and ensured that the changes were executed per the plan.
