To carry out a trial on a 6” inch abandoned main including identified tests to prove the concept of PRISM (Pipe replacement in situ manufacturing) technique. Write a closure report Including policy test results and lessons learnt and next steps to feed into the whole project objective plan.
To support the development and delivery of a safe and efficient suite of processes, tools and techniques to replace gas mains that significantly reduces the need for the excavation and reinstatement element of existing processes and thereby significantly reduce the costs and customer and stakeholder inconvenience and disruption.
This 6“ trial will provide a proof of concept for future trials on PRISM (Pipe replacement in situ manufacturing) technique to expedite commissioning of projects correctly targeted at accelerating the delivery of a commercial solution
Satisfactory evidence to support the PRISM technique and results that enable us to continue to the 12” trial.
