Urban Geotechnics

Supporting Clients and their Urban Projects

For over 20 years, Ayesa has successfully worked on urban projects across various ground conditions by supplying geotechnical engineering and below-ground design services.  Our team consists of geotechnical engineers, civil engineers and engineering geologists who deliver tailored solutions to meet individual urban project and client requirements.  We have extensive experience in design and construction in various ground conditions throughout cities in Ireland, the UK and the Middle East.

Advising Innovative Solutions

Cities worldwide are struggling with a myriad of environmental and social problems with air, water and soil pollution and crowded, ageing infrastructure.  Innovative solutions are essential to combat these problems by utilising underground solutions and maximising space.

Our geotechnical engineers contribute to exciting and challenging projects, many of which are major national and international schemes built within densely populated areas.  In the buildings sector, we have provided foundation and basement designs for The Shard in London, the New Children's Hospital in Dublin and the visitor centre at Titanic Belfast.

Often, we apply complex 3D modelling on projects to understand the impact on surrounding assets due to potential ground and structural movements.  We provide detailed earthworks and sub-structure solutions for large urban infrastructure schemes such as the Crossrail line extension in London, the Doha Metro scheme in Qatar and the M50 widening in Dublin.

Our expertise covers all aspects of geotechnical and geological engineering, from planning, investigation and feasibility studies to design, construction surveillance and operations and maintenance. 


Expertise In-Depth:

• Construction sequencing
• Earth retaining structures and excavation support systems
• Earthworks design for civil works
• Foundation design – piling and shallow footings
• Geological mapping and assessment
• Geotechnical analysis and design
• Geotechnical investigation and interpretation
• Ground anchors and anti-flotation tension piles
• Ground Improvement techniques
• Instrumentation and monitoring
• Numerical modelling
• Slope stability analysis in soil and rock
• Tunnelling, micro-tunnelling and pipe-jacking
