CON20002 - The Demolition of The Ammonia Washers at South Tees Site Company, South Bank Coke Ovens, Redcar Steelworks

South Tees Site Company Ltd (STSC) is a Government owned Company that is part of the BEIS (Business, Energy and Industrial Strategy) Department.

The site is classified as an Upper Tier COMAH site. STSC are in the process of decontaminating the former SSI assets in order to remove all Upper Tier COMAH materials, remove the site from the requirements of the COMAH Regulations and hence surrender the COMAH Permit.

The ammonia washers form part of the former SSI assets on the South Bank Coke Oven area of the Redcar site. Due to poor structural condition, STSC, as part of their commitment to the ongoing safety of the site, have taken the decision to demolish the ammonia washers.

The washers were subject to a dismantling project during 2019 and removal of access stairs, interconnecting platforms, man doors and some ancillary pipework has been undertaken. Due to an incident resulting in a fire in washers No 1 and No.2 during the previous dismantling project the dismantling of the washers was temporarily postponed. The incident is the subject of an ongoing Police and HSE investigation.

The primary aim of the successful contractor is for the safe demolition of all three towers as detailed below. However, at the time of the launch of this RFI, the root cause of the incident is yet to be determined. To this end the successful contractor will be asked to engage with STSC and the previous demolition contractor in order to insert agreed inspection points into the demolition programme. The aim is to allow key items of equipment to be viewed/inspected, wherever possible, which may assist in identifying the root cause of the incident.

The work comprises the demolition/dismantling of redundant Ammonia Washers No 1, 2 and 3 including associated pipework and ancillary equipment with the use of cold cutting techniques only.

In addition to the dismantling/demolition of the ammonia washers the main works includes:

• Removal and disposal of all asbestos containing/other hazardous insulating materials.
• Removal of contaminants from all process plant/equipment to include, where necessary, primary and secondary cleaning of plant/equipment by high pressure/low volume water washing with the appropriate collection of generated wash waters.
• Segregation and storage of demolition generated wastes (with the exception of asbestos waste) into suitable containers/skips provided by STSC. The specification of these skips and containers will be determined by the Principal Contractor in conjunction with STSC.
• Analysis of wastes is to be carried out in order to determine hazardous/non-hazardous nature and properties of wastes, with WAC testing to ascertain suitability for landfill if appropriate.
