This project consisted of replacement heating and domestic pipe services within the Main building, Science, Sports and ITC blocks over two phases. Due to time expired and inefficient piped services and plant we were appointed to carry out the full strip-out and replacement of the existing services throughout the main block and localised modifications within the modern sub buildings.

With the work due to be carried out across the school summer holidays, the discovery of vast amounts of asbestos containing materials throughout the building meant the project programme was extended to incorporate Easter and May Bank Holidays along with 3 weeks of the summer holiday to allow the initial asbestos removal enabling works to take place.

Critical ‘heating on’ dates had to be met. Whilst the strip-out of existing systems could be carried out during the remaining summer holiday period, the majority of the works were carried out in an occupied-premises, working in a phased manor with localised changeovers of services and incorporating working unsociable hours.

Phase 1

Replacement of secondary heating distribution system including:

• Stripping out of existing single-pipe system and Victorian cast iron column radiators
• Installation of new copper zonal distribution pipework for 86no. steel panel radiators and 12no. fan convectors and differential pressure control devices
• Secondary plant/pump replacement
• Associated control panels
• Replacement of heating boilers and flues to English Block
• Thermal insulation/Isogenopak
• BWIC including low level boxing in of all pipework

Phase 2

Replacement of Domestic MCWS and HWS distribution services including:

• Installation of new copper distribution pipework feeding all sanitary outlets throughout
• Stripping out of existing pipework incorporating localised shut-downs/changeovers onto existing sanitary outlets
• Secondary plant/pump replacement
• Associated control panels
• Thermal insulation/Isogenopak
• Installation of isolation valves, thermal balancing, thermal mixing valves to Science, Sports, ITC blocks
• Science block, conversion of CWDS to MCWS
• BWIC
