Adding Value through Ground Engineering

    Geotechnical Engineering Services across the Entire Project Lifecycle:

    Ayesa is a top 10 UK Ground Engineering Consultant according to revenue in 2023.

    When working on a project, how construction interacts with its surrounding ecosystems and ground conditions is often the source of the most significant risks and uncertainties. Ayesa has become an acknowledged leader within this sector, (We are ranked in the UK's top 15 ground engineering consultants) analysing difficult ground conditions on both greenfield and brownfield land, solving complex geotechnical challenges by providing robust and practical solutions for various development projects, whatever the size or scale. Our geotechnical engineering expertise can be applied effectively to projects, whether water, marine, energy, civil, buildings, rail and conservation.

    Our geotechnical engineering staff identify and mitigate ground-related risks through rigorous investigation, analysis and design. We have completed large-scale schemes across all construction sectors, providing designs including foundations, retaining walls, tunnels, shafts, earthworks and slopes. We form integrated geotechnical and structural design teams capable of providing fully coordinated solutions, maximising the reliability and efficiency of our projects. We assist with determining the optimal construction sequencing and provide practical and value-driven geotechnical solutions, such as ground movement assessments, contaminated land remediation and soil-structure interaction.

    We are equipped to manage the geotechnical inputs on projects from the initial investigation phase to on-site monitoring during construction. Our geotechnical engineers and geologists are industry leaders in specifying and managing geotechnical investigations and interpretative reporting. Numerical modelling has developed rapidly over the past decade, and often the quality of geotechnical investigative data is the limiting aspect for developing intricate models and assessments. We undertake complex 3D modelling for projects to investigate any impact on surrounding assets due to ground and structural movements. The use of ground engineering will help improve the design of structures and reduce asset-lifecycle costs by using the latest methods and technologies. staff will ensure the necessary data is captured during the investigation phase to offer clear benefits to the design and modelling phase – whether this is a city centre basement development or a large linear infrastructure project.
