A pressure testing certificate is only as credible as the provider behind it.
Pressure testing plays a critical role in construction and infrastructure projects, providing assurance that pipelines are fit for service. However, when questions arise around how a test has been carried out, confidence in the outcome can quickly be undermined.
This was the challenge facing Kane Group Building Services on a PE pipeline installation forming part of the Bermondsey regeneration project, a major mixed-use development in London. Previous testing had been undertaken, but concerns had been raised regarding the methodology used. As a result, confidence in the findings had been lost and an independent, compliant retest was required.
Connecting Clients with Trusted Pressure Testing Specialists
Working as a specialist subcontractor on the project, Kane Group needed to provide their client with confidence that the installation had been tested correctly and that any resulting certification would meet the required standard.
The project involved a 21-bar pressure test on a section of polyethylene pipework. Importantly, the issue was not that the pipeline had been proven to leak. Kane Group needed a specialist capable of carrying out a compliant pressure test and providing confidence in the outcome.
The Right Specialist for the Job
While pressure testing plays a critical role in infrastructure and construction projects, there is often little visibility into a contractor's previous testing performance, methodology or experience. This can make it difficult for clients to distinguish between providers and select a suitable contractor with confidence.
The Approved Contractor Network was created to address exactly this challenge.
The ACN comprises experienced pressure testing contractors who have demonstrated their capability through the successful delivery of projects using AHS equipment and have met specific performance, compliance and quality metrics.
The network promotes a consistent standard of delivery alongside greater transparency and traceability. This gives clients confidence that the contractor undertaking the work has the capability and track record required to produce reliable test data and certification.
For Kane Group, the ACN provided access to a trusted specialist with the expertise required to undertake the testing and provide the assurance their client was seeking.
Delivering the Testing
Through the Approved Contractor Network, React Commissioning was selected to undertake the testing.
Using AHS equipment and compliant pressure testing procedures, React attended site and carried out the retest required by Kane Group.
By engaging a specialist contractor operating within the AHS framework, Kane Group were able to obtain confidence that the testing had been carried out correctly and that the resulting certification could be relied upon.
Following completion of the project, Lee Garner praised both the quality of the service received and the value of having access to a specialist contractor through the network.
"I can't compliment them enough. The detail they went into and the situation they got us out of was superb. Our client was really impressed."
For Kane Group, the ACN provided access to the expertise needed to resolve a complex testing challenge and deliver a test certificate backed by a trusted pressure testing specialist.
