    Brief

    This project involves the stabilisation and rehabilitation of Graig Ddu Tip (RH077), a former coal and quarry site located in Dinas within Rhondda Cynon Taff County Borough Council. The site is situated on the northern slopes of Mynydd Dinas, accessible via Graig Ddu Road. The primary objective is to protect and upgrade local highway infrastructure by replacing failed drainage systems, repairing distressed road structures, and resurfacing the carriageway. This work is essential for ensuring road safety and functionality while addressing the structural challenges posed by the historic mining and quarrying activity. Suppliers and contractors with experience in ground stabilisation, highway maintenance, drainage infrastructure, and site remediation on challenging terrain are encouraged to express interest.
