The Mahall Bomonti Project located in Bayraklý, Ýzmir. It is currently under construction, and when completed, will comprise residential, office and commercial facilities covering an area of approximately 45, 000 m2. Within the scope of the project, a foundation excavation with a maximum depth of 18.5 m was proposed in the soft alluvial soil layers under a high water table. In order to ensure that the excavation was executed safely, without endangering the surrounding structures, a ground support system comprising a diaphragm wall supported by high-capacity prestressed anchors (SBMAs) was designed and constructed. The paper provides details on the calculated and observed deformations together with the design, construction phases and quality control tests applied during the implementation of the excavation support system.
