A cofferdam is an enclosure built within a body of water to allow the enclosed area to be pumped out or drained. [1] This pumping creates a dry working environment so that the work can be carried out safely. Cofferdams are commonly used for construction or repair of permanent dams, oil platforms, bridge piers, etc., built within water.
A cofferdam during the construction of locks at the Montgomery Point Lock and Dam A cofferdam is a barrier, usually temporary, constructed to exclude water from an area that is normally submerged. Made commonly of wood, concrete , or steel sheet piling , cofferdams are used to allow construction on the foundation of permanent dams, bridges, and ...
Upper coffer dam works completed. 31 January 2022 All the 48 barrage gates are fully erected and water can be stored in the reservoir to the extent permitted by the upper coffer dam design. 30 June 2022 Lower coffer dam works completed: 17 February 2023 [32]
A cofferdam is a small space left open between two bulkheads, to give protection from heat, fire, or collision. [2] Tankers generally have cofferdams forward and aft of the cargo tanks, and sometimes between individual tanks. [3] A pumproom houses all the pumps connected to a tanker's cargo lines. [1] Some larger tankers have two pumprooms. [1]
It would still help control floods and provide for irrigation and hydroelectricity, though at a reduced capacity. Most importantly, it would not raise its reservoir high enough to irrigate the plateau around the Grand Coulee. The dam's design provided for future raising and upgrading. [21] The east-side cofferdam after the west base was complete

Besides fulfilling this position for the government, Meigs was an inventor. He invented a "canvas coffer-dam," and pioneered the application of crude oil to dirt roads to improve driving conditions by controlling dust and mud. [1] [6] He also built and designed steamboats and steam dredge tenders.
The design for the Auburn Dam was changed to a concrete thick-arch gravity dam, to provide better protection against a possible earthquake induced by its own reservoir. [ 15 ] Through the rest of the 1970s, other possible designs were looked at but never implemented, while preliminary work on the construction site resumed.
