Any type of underground construction results in excavation and possibly groundwater induced surface settlements. Understanding ground movement due to underground construction activities and their effect on overlying / underlying structures is a complex process. Buildings made of masonry are brittle and sensitive to movements; existing tunnels may also be sensitive to deformations.

We tackle these types of problems by means of numerical modelling, where soil-structure interaction can be taken into account. We have developed a suite of design settlement assessment models for predicting surface settlements induced by tunnelling and construction of underground structures to estimate damage to buildings, infrastructure and other buried services.

Our Expertise:

• Prediction of settlements using empirical and numerical analysis
• Building impact assessment
• Prediction of total slope changes
• Impact assessment on other assets
