Massive Construction: Building a Billion Dollar Flood Defense System, FD Engineering Extreme Constructions Complete Series: The plan to build a surge barrier against the tides that cause the so called Acqua Alta has been underway for nearly forty years, but only now is the massive 7billioneuro surge barrier nearing completion. This documentary looks at the engineering, construction and instalment of this huge and unique mobile dyke that sits invisible under the Venice lagoon, until high tides trigger it to rise from the sea bed to protect the ancient City of Water. The last two stages of the construction of this enormous barrage involved placing the massive concrete underwater housing for the caissons that act as a barrier at the bottom of the lagoon entrance channels. The transport of the massive MOSE surge barrier and all its concrete and steel parts is a true feat of heavy lift technology and maritime engineering. Transporting the concrete beds re
