Project
A deep, small-diameter interceptor tunnel and consolidation tank system in karstic ground.
Interceptor tunnelling, deep shafts and a stormwater consolidation tank in highly variable ground.
Karst risk drove a probe-and-treat ground model, with contingency designs developed for unexpected cavities encountered during excavation.
