This project started in September 2022 and was completed January 2024. We were tasked by the client to install a replacement gas riser system to 3x 20-storey blocks just off Old Kent Road, London.

Scope:

• 6 x 90mm mains to bases
• 145m of excess pipework
• 882m of <1’’ welded laterals
• 492m of 2’’ welded risers
• 240m of 3’’ welded risers
• 222 lateral entry points
• 10m of excess pipework

Our responsibility for the job was to act as Principal Contractor and as such were in charge of CDM for the site which included planning, managing and coordinating the entire construction phase, producing a construction phase plan, managing health and safety throughout the construction phase, control of subcontractors, ensure site is safe for contractors, employees, members of the public & take steps to prevent unauthorised access to the site.
There were several challenges on these works. Our project was due to start around a similar time to a City of London sprinkler system replacement project was due to start. We held several pre-commencement meetings and also weekly calls to maintain a level of communication between the parties to make sure our works did not interfere with each other.
We started working on East Point in September 2022 and gradually progressed our way through Centre Point and finished on West Point.
Mast climbers were used for the WAH solutions and hoarding was constructed around the base of each building to deter and prevent access to the working areas.
