Lot 1: This notice is raised as Early Market Engagement only and does not constitute a call for competition. PCH are seeking to engage with suitably experienced Contractors and flue specialists to design, replace and lower the existing SE duct terminals to 3nr fifteen-storey apartment Towers in Plymouth. Works to the SE ducts are programmed to commence in summer 2022 and should be complete before September 2022 to avoid the requirement for temporary heating. The ‘SE ducts’ are a communal gas flue system commonly used around the mid-20th Century. Each of the Towers benefit from four SE ducts; two larger SE ducts serve gas-fired warm air heaters from 30nr apartments with two smaller ducts serving 15nr apartments each (90nr apartments in total per Tower). Each SE duct is topped with a terminal. The works comprise coordinating design of replacement SE duct terminals, isolation and capping of gas services/appliances to each apartment (phased per duct/Tower), road closures and crane lifting replacement terminals to roof level, demolition of existing concrete ducts and supporting structure, formation of new waterproofing upstands, supply and installation of new SE duct terminals, isolated flat roof works around each cowl and recommissioning of gas connection/appliances (full purge) through each Tower. This is together with all associated temporary works and any other works clearly apparent as being necessary for the safe and proper completion of the works. In addition, isolated corrosion treatment is required to roof parapet structures. Qualified gas operatives will be required to apply and obtain ‘approved contractor status’ from the PCH gas team prior to being able to work on any gas appliances. A working knowledge and justifiable experience of working on Johnson Starley warm air heaters is essential given that this is the predominant form of heating throughout the apartments. The Main Contractor will be responsible for undertaking the Resident Liaison Officer role to gain access to each apartment to undertake the gas isolation/recommissioning work and Principal Contractor duties under the Construction (Design and Management) Regulations 2015. Contractors should have experience of undertaking the Resident Liaison Officer role and managing gas safety works.
