According to the documents published in the Official Journal of the European Union, the Coal Authority the framework will be separated into five lots based on the type of work and it is seeking up to three suppliers for each of the five regions.

According to the Coal Authority, the number of suppliers is essential “to ensure sufficient resources and to minimise the risk of non-performance and taking into account the most economically advantageous option”.

The work will be split across regions defined as Scotland East and West; Northumberland, Durham and Cumbria; North, West and South Yorkshire; Nottinghamshire, Derbyshire, Leicestershire, Shropshire, West Midlands, Warwickshire, Herefordshire and Worcestershire; and North and South Wales, Pembrokeshire, North Gloucestershire (Forest of Dean), Cheshire and Lancashire.

Lot one comprises of rotary investigation drilling with the potential to undertake cementitious grouting for stabilisation of ground and infilling of ground collapses, mine workings and mine entries. Lot two will have a similar remit but allows for resin grouting.

Lot three covers ground investigation using small diameter rotary probe drilling within areas of restricted access, while lots four and five cover the same ground investigation work and includes remediation using cementitious and resin grouting techniques, respectively.

Successful bidders will enter into an NEC3 framework contract with the Coal Authority and individual work packages under the framework will be awarded under the NEC3 engineering and construction short contract

No value has been put against the work but the frameworks are expected to start in August next year.
