Our Role

Ayesa undertook the detailed structural and geotechnical design of the diaphragm walls, ring beams, counter walls, tympan walls and soft eye diaphragm wall panels to form the temporary shafts and to accommodate the tunnel boring machine. This included complex 3-dimensional geotechnical and structural modelling of the shafts. The role included preparing the geotechnical instrumentation and monitoring plans. Ayesa engineers also ensured that the diaphragm wall and ground movement predictions met specified design trigger levels.
