Intended for general application to ground investigation work, this specification includes associated Schedules and a Bill of Quantities. The Bill of Quantities is presented as an introduction and a comprehensive list of work items, which relates closely to the Specification items. This Specification may be used in conjunction with any suitable contractual agreement between the procurer and ground investigation contractor. The first edition of the Specification for Ground Investigation was published in 1993. Since then there have been many advances and regulatory changes affecting ground investigation, particularly in respect of contaminated ground and dealing with waste materials. This considerably revised and extended second edition of the Specification is the UK specification endorsed by the Highways Agency, Environment Agency, British Waterways and Network Rail and is intended for general application to all ground investigation work.
