Scope
We did the civil works for a deep seawater intake structure on the Mediterranean shore of the Sidi Kerir power plant near Alexandria. The main contractor was Archirodon Construction Overseas. The structure is 20 m Γ 20 m in plan and goes 15 m deep. It's a reinforced concrete basin, and it had to be built tight against the sea and proven watertight before we handed it over. We handled the full concrete package: the reinforced concrete raft foundation at the base of the excavation and the 60 cm-thick, 15 m-high retaining walls that form the intake chamber.
The walls carry openings and embedded provisions for the plant's intake pipelines. Each one was detailed with water-retaining joints and sealing systems to keep the structure leak-free at full depth. Once it was finished, the whole structure went through leak tests to prove the raft, the wall joints and the pipeline penetrations were all watertight. We delivered the works in 2009.
Cast a watertight 15 m-deep concrete basin right on the seashore, with pipeline penetrations passing through 60 cm walls under constant water pressure.
A reinforced concrete raft and full-height retaining walls, with water-retaining detailing at every joint and pipeline crossing, built to marine-grade concrete standards.
The finished structure passed its leak tests and was handed over watertight. It runs the power plant's seawater intake.
