How Massive Underground Construction Works ｜ Giant TBMs, Deep Excavation & Heavy Machinery

What does it take to build massive infrastructure beneath cities, rivers, roads, and unstable terrain? This engineering documentary explores underground construction, tunnel boring machines (TBMs), deep excavation, geotechnical engineering, ground anchors, waterproofing, culverts, ventilation, and pipeline construction. Discover how engineers control enormous forces using giant cranes, drilling rigs, TBMs, heavy machinery, and advanced construction technology. From 25-meter-deep excavations and massive tunnel systems to ground stabilization and pipelines across difficult terrain, every project demonstrates one principle: control the ground before the ground controls you.
