This pipeline presented extraordinary logistical and engineering complexities due to its route through critical infrastructure. The system traverses beneath a busy parking facility, descends a hillside, and runs under heavily trafficked railway tracks. Shifting earth from seismic activity and rail operations caused joint failures, particularly near railway easements.

Traditional excavation would have required closure of the parking facility, coordination with the railway on potential track shutdowns, hillside excavation, and work within restrictive railway easements. The client required uninterrupted railway operations and public parking access throughout rehabilitation. While the host pipe was maintained in good condition with sufficient tensile strength for multiple bends and operating pressure, its thick concrete construction and proximity to active rail infrastructure made conventional repair methods impractical.
