High-rise buildings pose new challenges for engineers, especially in the field of calculations
and design of above-ground structures, bases and foundations. Some consideration the anticipated responses
to adjacent buildings during construction are presented. This will require the design professional to survey
the condition of the adjacent properties to understand their present condition and fragility, establish
acceptable limits, conduct soil-structure analyses of various support systems and develop limits on their
respective movements, and develop a monitoring strategy. This paper shows the technology for support
excavation structures as shoring system for 1000 mm thick diaphragm wall, which is supported with four
layers of pre-stressed anchorages. The shoring system calculations had been designed by PLAXIS 2D, which
can assess in very detail the deformations and settlements in the soil. The basement walls are a formed with
reinforced concrete diaphragm wall panels, which are supported with ground anchors. The basement slab is
to be a pile-supported raft, which is a made up of discrete sections to accommodate thermal and lateral
movements. These numerical methods were a carried out within the investigation of the interaction of
anchored diaphragm wall of high-rise buildings with soils in the problematic ground conditions of Astana.
Recent advances in monitoring by using 3D laser-scanning technologies and acquiring quality information
about built environments using embedded and other advanced sensors give to engineers a real picture of soilstructure interaction. This information is combined with the design model to create an integrated model,
which is a dynamically updated during the construction period.
