Project
A 3.6-mile steel-lined pressure tunnel and two large-diameter shafts in an active fault zone.
Design and construction phase services for a critical regional water conveyance tunnel.
Crossing the active fault demanded exceptional seismic resilience: flexible joints, deformable lining segments and shafts designed for a full-life serviceability target far beyond code minimums.
