Taylor Woodrow worked on the scheme for the sustainable remediation of a 33ha site.

The site of the Cardiff International Sports Village was located on a man-made peninsular within the freshwater lake formed by the Cardiff Bay Barrage. It had a history of industrial and commercial land use. A sustainable remediation and ground improvement solution was therefore required in order for the mixed use development to proceed. The site also needed stabilisation of the bank which ran alongside the bay. The scheme was one of the largest bioremediation operations undertaken in the UK and all hydrocarbon-contaminated soils were reused on site.

Key points:


鈥� Providing adequate space and time for best remediation methods facilitates significant added value.
鈥� Remediation in winter requires significant additional measures to ensure successful progress and validation.
鈥� Early engagement with designers and regulators resulted in innovation and ultimately successful validation.
