Ground Stabilisation by Drilling and Grouting

Tender description

The Coal Authority (Client) was established by Parliament to undertake specific statutory duties, set out in the Coal Industry Act 1994, associated with licensing coal mining operations; managing property and the historic legacy arising from the ownership of the coal reserves and underground workings; settling subsidence damage claims not falling on coal mine operators and providing access to coal mining information. The Coal Authority has a legal duty under the Coal Mining Subsidence Act 1991, to repair properties damaged by coal mining subsidence in the five coalfield regions. The works are funded by grant in aid from central government, in order that the Coal Authority can discharge its statutory duty. The Coal Authority employs over 300, based mainly at the head office in Mansfield with some field staff remotely based in order to enable a fast response to incidents in the coal mining areas.
