Mega Construction Projects_ The Hidden Foundations Beneath the World’s Biggest Structures

Discover the hidden engineering beneath skyscrapers, bridges, ports, airports and offshore wind farms. This documentary follows deep foundation construction from drilled shafts, CFA and displacement piles to precast PHC piles, steel pipe piles, sheet walls, diaphragm walls, hydromills, caissons and offshore monopiles. See giant piling rigs, rebar cage machines, vibratory and impact hammers, barges and trench cutters push structural loads through weak soil into stronger layers far below. From 36,300-ton load tests to underground walls reaching 250 meters deep, this is how civil engineers build foundations strong enough to carry some of the world’s heaviest structures. The video also shows marine pile driving, river bridge pile caps, floating concrete caissons, corrosion repair and final load transfer.
