The caissons should each be constructed in one month’s time. The first caisson, C2, was completed in early November 2017 and was delivered to Monaco in late July 2018. The caissons will continue to be sent to Monaco and moved to their exact location before being sunk into place one-by-one. They are weighted with quarry materials for stability. The entire caisson belt will be installed over a one-year period.
