Delivering efficiency

Factory thinking, lean engineering and collaborative planning techniques reduced the time taken to refurbish each rapid gravity filter by 50% - and the overall duration of the project from 88 to 45 weeks.

We needed to upgrade the Strensham plant with new assets within a challenging 88-week timeframe. This would have been almost impossible without the extensive use of collaborative planning, lean techniques and ensuring the maximum work possible was manufactured off site. Our supply chain partners and Severn Trent Water embraced our collaborative planning approach.

This £8.6 million Strensham contract is one of the first where we have adopted a more standardised, systems-led engineering approach. We will be looking to use these techniques on similar projects in Asset Management Period [AMP] 6 in order to help our customers deliver new assets more effectively.

To achieve the AMP5 efficiencies a different way of working was needed. It was great to see how the project teams responded to the challenge.
