The buying organisation, The Coal Authority, aims to install a borehole to monitor mine water in the Barnsley-Manvers-Grimethorpe area. The project falls under the services category with a contract value of £800,000 and a future notice date set for November 30, 2024. The intended delivery time for operational readiness is by summer 2025, with specific drilling requirements and a design life of at least 20 years. This tender presents an opportunity for businesses involved in downhole services interested in environmental protection to participate. Companies specialising in drilling services and water monitoring technologies would be well-suited to compete. The project involves engaging with landowners and drilling a borehole to gather essential data, offering a chance for businesses to contribute expertise in enhancing mine water management strategies. The contracting authority, The Coal Authority, encourages innovative approaches that ensure accuracy and effectiveness in carrying out the monitoring borehole. ## Notice 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. 1. Background The mine water in the Barnsley-Manvers-Grimethorpe mine water block is thought to be rising. Recovered mine water in this area represents a potential risk to the overlying Permian aquifer, as well as surface water in the area. To assess the mine water regime, and inform future mine water management strategies, a borehole is required that would target the Brodsworth or Bullcroft colliery mine workings. Therefore, the Coal Authority (CA) requires a mine water monitoring borehole to increase the monitoring infrastructure in the area. The data from this borehole will be used to improve understanding of mine water in the Barnsley-Manvers-Grimethorpe mine water block, through water level monitoring and quality sampling. 2. Delivery The CA look to collaboratively engage with landowners to obtain access and a licence to carry out the drilling works. It should be noted that this engagement may take up to a maximum of 15 months, from initial point of contact however, in some cases this is significantly less. With this in mind, the Invitation to Tender is sent out part-way through this timeframe. Nevertheless, and to avoid any delays, the Contract will be awarded with a Contract Award Date and Start Date as two different dates. 3. Engagement Opportunities The CA are always looking for ways to improve and streamline projects. Due to the defined verticality requirements, it is envisaged that the most robust and reliable method of completing the mine water monitoring boreholes is by drilling a pilot hole using a wireline coring system, followed by reaming to the required diameter(s). However, the CA would welcome your feedback on this including any other methods that may be deemed more suitable to guaranteeing verticality such as directional drilling. ### Lot Information Lot 1 Open tender.
