Execution Complex engineering execution in an urban environment: excavation and shoring with advanced technologies

The Yitzhak Sadeh project in Petah Tikva is a large-scale development divided into two lots. It includes five towers with a commercial ground floor, public buildings, kindergartens, residential units, and four to five levels of underground parking. The project is being built in the heart of an established residential neighborhood, next to an active kindergarten.

The preliminary works required the complex demolition of seven old railway-style buildings, the dismantling of existing infrastructure, asbestos removal, and the felling and relocation of trees. As part of the project, the company is responsible for extensive foundation works, including excavation to a depth of approximately 21–22 meters, with a total volume of approximately 160,000 cubic meters.

The shoring system consists of 64-cm-wide slurry walls extending to a depth of 30 meters, totaling approximately 8,500 cubic meters. These are constructed, among other methods, using a new and advanced hydromill machine. In addition, the works include the installation of approximately 1,100 temporary steel ground anchors in four to five rows, as well as preparations for groundwater pumping and dewatering.

The execution team faces significant engineering and logistical challenges, primarily the simultaneous execution and management of works on both lots while casting deep elements. The works are carried out in accordance with the site’s geological characteristics and varying soil layers, ranging from clay to loam. Meeting the constraints of this dense urban site relies not only on technology, but also on highly capable management and skilled personnel, enabling the team to optimize work fronts and maintain progress on site.
