Investigations have been undertaken to improve techniques for the prediction and control of ground vibration caused by civil engineering construction works. Contemporary damage and nuisance criteria are reviewed and factors affecting the input and propagation of ground vibration are discussed. Field data from numerous sites in the uk are summarised to provide some guidance as to the relative importance of various sources (eg, traffic, piling, tunnelling, blasting). a methodology for trial blasting is given with recommendations for the deployment and specification of the equipment. Data processing and presentation format is described and a 'site specific' scaling method given which provides improved correlation between peak particle velocity and scaled distance. The use of peak particle velocity as a damage-hazard specifier is discussed in relation to other dynamic parameters which also effect damage to structures. Options regarding the distribution of vibration associated risks between employer and contractor are considered in the context of legal and contractual obligations.
