Vital Energi has awarded Aarsleff Ground Engineering a package of foundation work for a scheme to create the Leeds Pipes district heating network for the city that will see the heat created at a council recycling facility used to provide a district heating system.
Under the deal, Aarsleff will deliver driven steel tube piling, mini bored piling, king post wall and drilling and grouting work for the system’s back up equipment at Saxton Gardens for design and build contractor Vital, which is working for Leeds City Council.
The work is a key part of the £35M network that will connect the Recycling and Energy Recovery Facility in east Leeds to the network that will provide hot water and heating to almost 2,000 homes and businesses via underground pipes.
Ground conditions and logistics at the site are challenging and called for a number of solutions, including grouting of former coal mine workings and mini piles to manage restricted headroom.
“Due to many areas of the site being close to the foundations of existing building walls and underground services, it has been necessary to work with extreme caution and assess all risks prior to drilling,” said Aarsleff project manager Chris Purvis. “Having assessed detailed site plans, made suitable and sufficient assessment of the risks posed by those hazards and co-operated with principle contractor Vital Energi, we have made sure any rules or agreed methods of working are strictly adhered to.”
