Ground engineering and underground structures
At Ayesa, we have a team made up of more than 70 experts in geology and civil engineering with extensive experience gained through projects on all five continents. We don’t just carry out geological and geotechnical studies but also offer the most suitable and cost-effective technical solutions for each case, based on our expertise in this area.
The geotechnical studies we have undertaken for civil engineering projects involve more than 1,000 kilometres of linear infrastructure. These have seen us participate in all phases, from initial surveys through to detailed engineering, as well as provide technical assistance during construction.
We have extensive experience in geological studies and mapping. As such, we have carried out work involving all kinds of geological formations, and are able to assess and mitigate geological and geotechnical risks, undertake the geotechnical characterisation of soils and rocks, and design, manage and supervise geotechnical investigations. We also have experience in the field of slope engineering, including soil stability and foundation design, and soil improvement. We use various solutions and tools, from geotechnical ground modelling software (2D and 3D) and geotechnical tunnelling software, such as FLAC3D, MIDAS GTS, PLAXIS 2D/3D and Rocscience, to BIM technology for geotechnical design work.
In terms of tunnels, we have participated in varied projects spanning more than 480 kilometres. Whether using tunnel boring machines, the New Austrian tunnelling method, or cut and cover involving diameters of up to 14 meters, we offer services in many different areas, including transport and water supply. These cover feasibility studies and cost analysis, functional and topological design of tunnels, and alternatives analysis, in addition to instrumentation analysis and geotechnical monitoring. We also carry out analyses relating to construction methods and specifications for tunnel boring machines, and design precast concrete segments for lining tunnels. We offer drainage and waterproofing, cut and cover, and soil improvement services. What’s more, we provide technical assistance during construction, as well as perform inspections and improve existing tunnels.
