Poringland Scheme

Daniel Richardson was approached by Mick Damen and was tasked with the job of supplying SMR as an alternative backfill on a Balfour Beatty scheme at Poringland in Norfolk. The scheme is 11.4kms long to replace an old water main through the centre of the village and connect all the new supplies.

After meeting with the site agent Chris Taylor and walking through the scheme to ensure we could meet his requirements, it was agreed. SMR would be the best solution for this work. Chris Taylor had provided ourselves with samples from trial holes he had excavated so we weren’t hit with any sudden surprises.

We came the a mutual agreement that our mobile SMR batching plant wasn’t suitable due to the amount of space available, but as was pointed out we have our hub site in Morningthorpe less than 10 miles away from the scheme. We decided we would deliver the SMR to site using our 8 wheeled grab lorries the driver would help backfill the trenches and take a load spoil away to bring back to Morningthorpe to be processed.

The benefits of using the SMR on any scheme are the massively reduced cost of muck away and the import of virgin aggregates. The cost of virgin aggregates is only going to rise in the upcoming years as is the price of muck away. By using SMR it also reduces the customers carbon footprint in some cases by up to 50%, Chris Taylor isn’t far off this 50% mark on the Poringland scheme.

Between Richardson Recycling, Mick Damen and Chris Taylor we have managed to save Balfour Beatty and the @one alliance £23,173 this was possible through the use of SMR as opposed to traditional backfill methods.

If SMR wasn’t used the total bill so far would be £46,770 to date. We have managed to reduce this to £23,597 by using SMR.

To give you a brief idea here is a quick break down of what has gone into the scheme

  • 1,474.84 tonne of SMR.1,474.84 tonne of SMR.
  • 1,100.78 tonne of spoil removed free of charge (SMR tip) to go back to the hub site for processing.
  • 374.06 tonne of non-recyclable waste to landfill.

If tradition methods were used this would of resulted in 191 lorry movements to import and export materials. Between the three of us we managed to reduce this figure to 119 lorry movements saving 72 lorry movements resulting in a reduced carbon footprint making Balfour Beatty a greener company.

The scheme is still on-going and I expect to see more savings out of this scheme as these figures are just to date

I would also like to mention the fact that there haven’t been any defects so far on this scheme using SMR. All of this is helped by the good working relationship that is between ourselves and Balfour Beatty, the gangs who work for Chris and Mick and Richard Moore from West Norfolk Surfacing and his team who have also played a massive part to make all of this achievable.
As you can see by the use of SMR it makes a more sustainable future for the utilities sector and civil engineering and a greener, cleaner future.
