Mott MacDonald Bentley (MMB) received three awards at this year’s ICE East Midlands awards gala, all for our project at Stoke Bardolph Thermal Hydrolysis Plant, delivered with Severn Trent Water. The team picked up awards for Large Project of the Year, Team Achievement and Sustainability.
Awarded outside of our existing framework agreements with Severn Trent, the new £42m Advanced Anaerobic Digestion facility at Stoke Bardolph turns sewage into biogas that is exported to the gas network and treats the remaining solids so that it meets the highest standards for use as a fertiliser. The aim is to increase the yield and improve the quality of the biogas and cake produced at Stoke Bardolph, products that re-used for power and in agriculture.
The team applied our Quality, Cost and Efficiency strategy to see how things could be achieved Right 1st Time, and, with a complex range of mechanical plant, Modern Methods of Construction (MMC) was the key. Having key work packages and mechanical items built away from site meant that on-site demolition and civil work could progress at the same time. Packages were then delivered to site for rapid installation, compared to a traditional on-site approach with a lengthy assembly and installation period. The boiler house is a great example of the benefits that MMC brings. We worked with our expert supply chain to learn from previous projects we’ve delivered together. As a result, the boiler house was manufactured, fully assembled and tested off-site, before being separated into modules for delivery and installation at site. The modular design, including the electrical system, used innovative quick-fit connections between sectors. Our approach saved 26 weeks on site.
The energy saving features of this plan, together with the sustainable products being produced (gas to grid and class A agricultural fertiliser), make it another in the growing suite of innovative step change projects that the water sector is implementing. The project has also been named a finalist at the British Construction Industry Awards two years running: in 2021 for Industry Transformation and Innovation, and in 2022 for Utility Project of the Year.
