The scope of work of this proposal is to develop a robust performance specification for the use of polymeric pipe lining technologies within multi-occupancy buildings.

The output would consist of an industry agreed standard for the performance specification and targets for any coating/lining system for the coating of small bore (predominantly below 4-inch diameter) gas pipework systems in the property types described above. The output would enable the validation of any technology in this application and the demonstration of ‘fitness for purpose’ both technically and the from customer perspective such as speed and inconvenience.

The development of a specification test procedure protocol which can be conducted by any party on a coating/lining system to enable the validation of any technology for lining risers and the demonstration of ‘fitness for purpose’.

Specifically the objectives  of the project will be to deliver:

  • A clear definition for the scope for the specification so that potential solution providers have a very clear understanding of the application and nature of its purpose.
  • A comprehensive objective technical specification (Gas Industry Standard) to include all relevant design & performance requirements  that all networks are in agreement with and fully approve within the scope and timeline of the project taking into account the different starting positions of each of the networks
  • A clear definition of the varying degrees of repair; permanent, interim and temporary; as well as a definition as to the difference between a repair and a refurbishment.An objective customer specification agreed by all participating networks
  • Define what a suitable and sufficient design and performance specification should look like for the complete system in order to demonstrate compliance with relevant legislation
  • Demonstrate compliance and assurance of fitness for purpose.
  • A clear definition of the relevant QA/QC protocols that are required in order to ensure such a system consistently delivers an installed product that meets the performance requirements of the specification
  • The development of a risk scoring model which would take account of the delivery systems and any potential safety or environmental factor associated with these
  • The resultant specification test procedure protocol which can be conducted by any party on a coating/lining system.  A specification designed such that proposed compliance testing costs do not prove prohibitive and deter technology innovators.  A goal of less than £100k at 2014 pricing has been set for a testing regime conducted by an external third party test house
  • Consult with providers of potential solutions to understand the opportunities and difficulties they see in applying lining systems in riser situations
  • Development of a Gas Industry Standard that is agreed unanimously by all participating networks, providing a comprehensive objective technical specification to facilitate the evaluation, verification and certification of new innovative polymer lining techniques for multi-occupancy gas risers.

  • An objective customer specification agreed by all participating networks

  • Successfully designing a specification test procedure protocol which can be conducted by any third party test house, with appropriate accreditation, on a prospective riser coating/lining system that can be delivered at a cost of no more than £100k at 2014 pricing.

  • Successfully designing a risk model to assess delivery method
