The project was challenging because of the sensitive environmental conditions. The construction site was situated in a protected dune area characterised by highly permeable dune sand. Because of the special location of the construction site, the environmental impact of dewatering had to be investigated in detail.
Gewan Island, originally also called Al Mourjan Island, is being developed next to The Pearl in Doha, Qatar. Part of the works consists in constructing a large underground parking in the middle of the island and a 1.3 km quay wall, both carried out in dry conditions. AGT, in close cooperation with Medco, organized the field testing, designed the dewatering, and analyzed the monitoring results during the dewatering works.
