Construction impact - prediction and assessment of damage from ground movements (C796)

This guidance has been prepared in connection with the prediction, assessment, and control of damage to existing building stock resulting from construction-related ground movement.

It is intended to provide a clear framework for assessing impacts to modern steel and reinforced concrete frame structures, together with a variety of cladding systems, and is appropriate for a variety of stakeholders.

Historically impacts of ground movement on existing structures have been described in terms of limiting tensile strain and crack width.

It is often forgotten that these damage classification systems were developed for masonry structures and are of little relevance to a large proportion of modern structures.

It includes worked examples demonstrating how the proposed methodology can be applied to real-life scenarios.

Engineering requires a thorough knowledge and understanding of basic principles and the application of sound engineering judgement.

This guide is not a substitute for professional knowledge.

If in doubt, seek appropriate advice.
