Underground Space

Supporting Urban Development

Population growth, urban development and the requirement for environmental preservation have led to underground space becoming increasingly important in solving urban problems.  Ayesa has been involved in a wide range of projects in the underground space sector, providing design services to clients throughout the project cycle from initial concept design through to detailed design and construction supervision to solve critical infrastructure needs.  Our team of geotechnical engineers, structural engineers, engineering geologists and civil engineers deliver project and client requirements in areas such as tunnelling, deep shafts, temporary works, retaining walls in a variety of ground conditions throughout Ireland, the UK and the middle east.

Our team of engineers are regularly involved in challenging and complex projects working directly for developers, as well as supporting contractors with design and build services. 
In Qatar, our role included the selection of the tunnel alignment and shaft locations and the design of permanent and temporary shafts for the Lusail Expressway.  While, as part of the Elan Valley Aqueduct, we designed several TBM (tunnel boring machine) launch and work shafts including a 30m deep, 13.5m diameter permanent secant pile wall-drop shaft.

As part of the New Children’s Hospital project, in Dublin, our appointment included the detailed design of close to 1km of permanent secant pile wall for the triple-level basement. 
Through close collaboration with our clients and technical expertise and experience in this area, we provide efficient and effective design solutions.
