UK Public Sector Contracts & Tenders

The Coal Authority (CA) is a non-departmental public body and partner organisation of the Department for Energy Security and Net Zero (DESNZ) with a mission to make a better future for people and the environment in mining areas. The Coal Authority manages the effects of past coal mining, including subsidence damage claims which are not the responsibility of licensed coal mine operators. It deals with mine water pollution from both coal and metal mines and other mining legacy issues. The Coal Authority owns, on behalf of the country, the majority of the coal in Britain, and licenses coal mining. We use our skills to provide services to other government departments and agencies, local governments and commercial partners. We contribute to the delivery of the UK Government's Industrial Strategy and the environmental, social and economic priorities of the UK, Scottish and Welsh Governments. By sharing our knowledge and expertise we support them, and our partners, to create cleaner, greener nations for us all. We currently have the capacity to treat 220 billion litres of mine water every year. Treating mine water has directly protected and improved over 350km of rivers, protects several important regional aquifers, enhances biodiversity and provides local amenity land. By treating the mine water we have prevented nearly 4,000 tonnes per year of iron solids and other pollutants entering watercourses or aquifers. Last year 89% of the iron solid waste was recycled or reused. We are responsible for protecting the environment by addressing and mitigating the environmental impacts of coal mining, our Business Plan for 2022 to 2025 provides an overview of the Coal Authority and explains our main priorities for the period, along with the organisation's 10 year vision. Our work involves monitoring and remediating contaminated land and water resulting from historical mining activities. The Coal Authority manage over 80 mine water treatment schemes across Britain, handling and treating over 112 billion litres of water every year. We invite you to tender for the delivery of our Operations and Maintenance Services Contract. The services required are detailed within the Scope and tenderers are advised to read and consider all aspects of the tender documents before preparing your tender submission. The aim of the provided documents is to outline the minimum technical and performance levels required by us should your organisation be awarded a contract. Tender documents and the ability to tender for this opportunity are freely available to all parties and can be accessed on our tender portal InBye Instructions for accessing the documents and making your submission can be found in a later section of this contract notice.

The Coal Authority (client) invites you to tender for the drilling of a mine water monitoring borehole to assess rising mine water on the surrounding environment at Westleigh, Wigan. A review of the mine water block by the Coal Authority has highlighted that mine water levels in the area could be elevated in respect to the rest of the block. There is potential for elevated mine water levels which could pose a risk to the overlying drinking water aquifers. Therefore, the Coal Authority requires construction of a borehole to intersect flooded underground workings at the former Priestner's Colliery at Westleigh, Wigan. The proposed borehole is to be used to improve understanding of mine water in the Golborne, Bickershaw and Parsonage mine water block and will be used for water level monitoring, water quality sampling and abstraction of water.

The Coal Authority wish to appoint a contractor to carry out a mine water pumping test in Langwith mine shaft at the former Langwith Colliery, Derbyshire, centred on approximate Ordnance Survey National Grid Reference (OS NGR) SK 529 706. The aim of the pumping test is to: • Test the suitability of the mineshaft for pumping; • Test hydraulic connection to nearby monitoring sites; • Test the chemistry of the pumped mine water at the site. • Assess the rate of recharge to the mine workings;

In 2011, the Water and Abandoned Metal Mines (WAMM) Programme was set up between the Environment Agency, Defra and the Coal Authority to address pollution of rivers by abandoned metal mines. Currently, the Coal Authority operates four WAMM mine water treatment schemes, each using a different treatment technology, which are improving water quality in about 20 km of rivers. In January 2023, Parliament adopted a statutory metal mines target, under the Environment Act 2021, to halve the length of English rivers polluted by harmful metals from abandoned metal mines by 2038. The Government's Environmental Improvement Plan (EIP), published in January 2023, estimated that to achieve this long-term target would likely require around 40 new mine water treatment schemes and a similar number of diffuse interventions. The EIP set a non-statutory interim target to construct 8 mine water treatment schemes and 20 diffuse interventions by 31 January 2028. To help deliver the interim and long-term targets, the WAMM Programme is currently investigating active treatment options for mine water discharging from abandoned metal mines by undertaking active treatment trials on up to five sites This opportunity is now open with a submission deadline of 29 October 2024 All interested parties are advised to visit each site to familiarise themselves with the sites layout, limitations, restrictions and access. Visits to the premises must be made by appointment only with the Coal Authority . There is limited parking at each site, interested parties shall only attend at the agreed time provided by the Client.

The Coal Authority is looking to award a number of packages of work through this tender ranging from 1 no. of the active trials up to 5 no. active trails. These may be at any of the 5 identified sites. The Coal Authority reserves the right to award to multiple parties depending on the proposals provided during the tender period. Tenders shall be scored on the basis of most advantageous economic tender against criteria to be published in the tender documents. The appointed party / parties shall design and supply a suitable pilot scale active treatment plant for each of the mine water sources to be treated. The appointed party / parties shall provide an individual report at the end of each trial detailing the outcomes.

The Coal Authority requires a service provider who can design, install and analyse data from Monitoring devices for use with Buildings or Landscapes which may be subject to Movement. We will also require the interpretation of this data in order to enable us to advise if movement is due to the impacts of historic mining or some other cause. On occasion these services will need to be deployed at pace in order to establish if there is a need for residential evacuation. We also require that appointed organisations act as an expert witness should any situations arise where our judgement is called to a tribunal. It is intended that Lot One will mainly be used our our Public Safety and Subsidence department for the monitoring and analysis of Structural damage caused by Historic Coal Mining. Other departments and permitted bodies may also make use of the Lot. It is intended that Lot Two will mainly be used our our Tips Response department for the monitoring and analysis of Landscape damage caused by Historic Coal Mine Tips. Other departments and permitted bodies may also make use of the Lot. The procurement documents are available for unrestricted and full direct access, free of charge, at https://inbye.coal.gov.uk/s2c/

The Coal Authority invites you to submit a tender for the provision of services relating to condition monitoring on land and structures. We are offering this Framework opportunity on the basis of a 4 year contract.
