The engineers will design and build a temporary wall, most likely by piling into the seabed or carefully sinking precast concrete elements to create a cofferdam
in the water across each end of the tunnel.
Dizzying shots show the central cofferdam
, with the central pylon beginning to take shape.
Engineering experts overseeing the project said the torrential rains brought about by the LPA and 'Agaton' caused the base of the cofferdam
to scour and totally submerge the structure.
Indeed, the colossal podium not only covers the entire 123,955m2 plot, but extends for four basement levels below grade, and all on a site immediately adjacent to the open water of the Dubai Creek - a situation that has required the erection of a cofferdam

She was previously on hand to see the first cofferdam
section, used to lay the foundations for the bridge's central towers, sent out from the dock at Rosyth to take up position in the Firth of Forth.
In a partnership dedicated to temporary cofferdam
dewatering on a wide variety of jobsites, including construction, remediation, rehabilitation, flood protection and in-water inspection, Rain for Rent and Portadam have merged industry-leading expertise and operational resources to deliver optimal performance and efficiency.
The firm had already taken delivery of steel piles to be used to build a cofferdam
at its Graythorp site, near Hartlepool.
The nearly three-day-long inspection was also successful in identifying the cofferdam
, a piece of containment equipment used during the Deepwater Horizon response, as the probable source of the surface sheen.
CEI also announced that it began building a cofferdam
on the upper part of the Mtkvari HPP to ensure a dry working environment for the main dam construction works.
A Wildish Construction crew is building a cofferdam
with the sandbags so it can then install a 96-inch pipe in the river for the Metropolitan Wastewater Management Commission.
Cardiff, by depositing its unwanted refuse in a constructed bund or cofferdam
at sea on the mudflat area, could then have a solution to both problems, land increase and save money at an expected pounds 4m per year.
will be built to hold the water back and silt curtains will help prevent material from moving from one side of the lake to the other.
