Remediation and Validation


Based upon the data obtained during our own site investigation or third party information we can carry out an Options Appraisal or design a suitable Remedial Strategy which will be suitable for submission to the Local Planning Authority and in the case of residential developments, NHBC, to obtain agreement in principle to the development proposals. This will utilise our specialist risk assessment skills and in depth knowledge of remedial techniques to provide the most cost effective and sustainable solution.


In addition we can design a Specification for Earthworks and Highways works at the site and undertake supervision, on-site advice and validation of the earthworks.


Where developments have land quality planning conditions associated with contaminated land, our expertise includes supervision and validation of the implementation of remedial strategies, ensuring remediation works are completed as approved.


On completion of remedial works (either contamination or geotechnical/earthworks) we prepare a Validation Report which is proven acceptable to Local Authorities and NHBC and which provides a thorough and concise record of the remediation process which occurred on the specific plots.
