Summary of the contracting process

The procurement process for the "Nant y Mwyn 25-26 Scour Protection Works" was initiated by the Mining Remediation Authority, a central government public authority headquartered in Nottinghamshire, United Kingdom. The contract was awarded to SANCTUS LIMITED for addressing the erosion of spoil heaps along the Nant y Bai watercourse. This comprehensive works project requires installing scour protection measures such as rock-filled bags, geotextile matting, silt traps, and possibly using helicopters for material placement to minimise ecological impact. The procurement was conducted through open competition, with the planning and award stages progressing to completion between November 2025 and January 2026. The project is set to commence on 16 February 2026, with completion aimed before 29 May 2026, though extensions are possible due to environmental conditions.

This tender offers considerable growth opportunities, especially for SMEs experienced in environmental protection and infrastructure projects. The nature of this work, focused on excavation at archaeological sites, makes it ideal for businesses with expertise in eco-sensitive construction and erosion control. Given the specialised requirements and the substantial budget of approximately £151,416, this project provides a lucrative prospect for firms capable of delivering technical innovation in partnership with government entities. The emphasis on environmental compliance and heritage protection further necessitates firms with robust methodologies to prevent ecological and heritage disruption.

Notice Description

The purpose of these works is to prevent the Nant y Bai watercourse from continuing to scour (causing active erosion of) spoil heaps that make up its banks and causing mobilisation of metal-rich spoil into the watercourse. It is proposed to install a mixture of scour protection interventions including rock filled rolls and bags, geotextile matting and wooden stakes at a number of discrete areas along the bank to stabilise the spoil and prevent ongoing erosion by the Nant y Bai. We would welcome input from the Contractor regarding current design methodology based on previous experiences. The Works comprise the following: * Install scour protection measures in accordance with the drawings; * Install slope stabilisation measures in accordance with the drawings; * Supply and install 150No. rock filled bags as specified on the drawings and as directed on site to provide scour protection in Areas 3, 5 and 6; * Translocate Purple Moor grass into the working area in accordance with the drawings. The source of Purple Moor grass to be agreed with the ecological supervisor but shall be within the Site; * Install silt traps in accordance with the drawings; * Install an overland pipe with associated capture structure and outfall structure in accordance with the drawings; * Deliver plant and materials along designated routes to limit impact on the protected ecology and provide any equipment necessary to minimize the impact on the designated routes. This may include helicopters to aid in load lifting and placement of rock roll bags; and * Plan and execute temporary flow diversion measures to enable the Works in the river bed to be completed. The Works must be carried out, including transportation of plant and materials, in a way that: * Does not cause undue harm to the local ecology, including plants, trees and particularly the protected Calaminarian habitats (comprising metallophyte flowering and non-flowering plant species); * Does not damage local heritage features, including historic mining structures and artefacts; * Does not cause undue disruption to the local community; * Does not cause damage to existing services; * Does not cause damage to the forest track road, * Is in accordance with the relevant Environmental Action Plan (EAP) as prepared by the Mining Remediation Authority and agreed with NRW.
