Ground Stabilisation by Drilling and Grouting Framework

The Coal Authority (Client) was established by act of 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 coalmining 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 people, 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.

The Coal Authority is funded by grant in aid from the Department of Energy Security and Net Zero (DESNZ)

To fulfil our legal obligations a Re-Tendering exercise was conducted in order to replace the previous Framework which expired on the 1st of March 2024

The new Framework will comprise of three Lots with the following lot structure.

Tenderers were free to price for all Lots or the Lots of their choice.

Lot One: Drilling and Grouting with unobstructed open access equipment

Lot Two: Drilling with restricted height / restricted access equipment

Lot Three: Drilling and Solution Grouting with restricted height / restricted access equipment

The works for this Framework will mostly be based over the UK Coalfields and the three Lots are further broken down into the following five regions.

• Region 1 - Scotland East and West
• Region 2 - Cumbria / Northumberland / Co.Durham / Durham / Sunderland / Newcastle
• Region 3 - North Wales / Cheshire / Lancashire / Merseyside / North Yorkshire / West Yorkshire
• Region 4 - South Yorkshire / Nottinghamshire / Derbyshire / Leicestershire / Staffordshire / Shropshire / West Midlands / Warwickshire / Herefordshire / Worcestershire
• Region 5 - Somerset / South Gloucestershire / Bristol / South Wales / Pembrokeshire / North Gloucestershire (Forest of Dean)

This is a reactive Framework with no guarantees of work and an awarded value of between zero and £9,750,000.00 which will be spread unevenly across the three Lots and Geographic regions depending on the work which becomes required.
