The dredging of a completely new site, requires careful investigation of site conditions, the ability to cope with tough and unexpected materials, the acquisition of expensive plant and the disposal of capital dredged material. Plus, since the risks are much higher than maintenance dredging, and the measurement and payment methods are different, contracting also needs very careful consideration. This book draws on the experience of a variety of expert authors to explain how to avoid operational problems, high maintenance costs and how to minimise the environmental impact.
