Haulbowline Island in Cork Harbour was the location of Ireland’s only steelworks which operated between 1939 and 2001. From the early 1960s, steel slag waste from the steel production process was deposited on an area of reclaimed foreshore, which became known as the ‘East Tip’. This project involved the remediation of the East Tip and its transformation into a public recreational amenity.
RPS, appointed by Cork County Council, delivered innovative and sustainable solutions at each stage of this complex project, from inception to conclusion. Initial stages included the preparation of an EIS, waste licence and planning applications for the remediation work. RPS managed a number of advance works contracts, the procurement process and construction stages of the main remediation works.

The remediation works on the East Tip posed significant contractual, environmental, health and safety risks, in addition to strict conditions set out by the EPA Waste Licence. The nature of the waste material, the existing landform on site, along with the marine location and foreshore tidal zone presented a number of complex challenges.
Site investigations had identified evidence of asbestos on site as well as other hazardous waste in the slag waste. In addition, there was uncertainty regarding the processing of the large slag stockpiles on site. The ground conditions, a soft marine alluvium below concrete-like slag deposits, had to be managed to ensure the constructability of the perimeter structure in the foreshore.
The key challenges were to deliver an innovative design solution which addressed the remediation objectives and to manage the significant contractual risks.
An NEC Option C (Target Cost with Activity Schedule) contract was utilised on this project. This facilitated greater collaboration with the contractor and the allocation of the financial risks associated with these elements of the works more evenly between the Employer and Contractor.
