Ground movements caused by construction activities such as basement excavation or tunnelling have the potential to cause damage to neighbouring structures or services. This guidance will identify the principal sources of ground movements and the methods for their prediction using empirical and analytical methods. It will provide information on commonly adopted control measures to control ground movements from initial design through to construction including temporary works. It also aims to provide guidance on permissible movement for different structure types dependent on their condition and structural characteristics and how this might be achieved by monitoring. For example new structures such as framed buildings founded on deep foundations with cladding respond differently to masonry structures and a serviceability failure is defined differently.
The guidance is aimed at addressing the immediate, short term construction issues as well as the long term maintenance aspects. This will be of particular benefit to large scale projects in the infrastructure pipeline where construction impact beyond the immediate construction phase will be a long term risk. The guidance will enable those with a role in managing construction impact from ground movement to better understand the impact and good practice mitigation strategies.
- Identify common sources of ground movement and their methods of prediction using empirical and analytical methods.
- Provide guidance on permissible movement for different structure types and building systems dependent on their condition and structural characteristics.
- Show how current monitoring systems can provide information to maintain effective movement control.
- Include a number of case studies to show good practice implemented successfully.
- Outline the benefits of using good practice procedures.
- Engage with professional bodies, developers, local authorities, insurance organisations, buildings and infrastructure managers, façade engineers, tier 1 and 2 contractors, architects and designers and those with a role in managing construction impact from ground movement i.e. a multi-disciplinary approach.
