The effect of large basement excavations in urban areas and the possibility of excessive building movements causes concern for adjoining owners and building owners alike.
By careful design and analysis basement construction can be carried out in a safe and predictable manner. With the benefit of a detailed geological assessment the project structural engineer can predict ground movements likely to be caused by the construction process. Specific site investigations and geological assessments are now a prerequisite for planning approval in many London Boroughs and will also provide factual data on the possible effects of basements on ground water flows.
