London 2012 Olympic Games

john_armitt_visitThe building of the infrastructure for the London 2012 Olympic Games was the largest construction project in Europe at the time and Evans Concrete were proud to be involved as a key supplier for several key elements of the build.

Evans became involved because of it’s relationship with Balfour Beatty and then entered an open tender process which culminated with the first contract being awarded in January 2009 to supply:

  • Bridge Decks
  • Parapets
  • Edge Beams
  • Infrastructure works for access to the main stadium

By the end of the project Evans had won 30 orders to supply 5300 m3 or 13,750 tonnes with a total of 8600 units.

Throughout the project it was important that key personnel were involved in the process to ensure everything was kept on track, which included a two day trip to the East Midlands organised by EMDA, John Armitt, chairman of the Olympic Delivery Authority (ODA), who visited Evans Concrete.

Sustainability and the Environment

One of the key elements of the tender process was to have sustainability and the environment front of mind. That’s why we implemented various processes to ensure as little impact as possible. This included:

  • Recycled aggregate could be used in the construction of the temporary bridges
  • Recycled concrete aggregate was processed at our factory
  • Special concrete mix was developed – 20% of the main aggregate replaced with recycled concrete aggregate and 36% of the cement replaced with ground granulated blast furnace slag (GGBS)
  • The combined effect of these two initiatives – 15% of the final product was made using recycled materials
  • The 600 temporary bridge planks supplied weighed approx. 6000T – approximately 900T of this was from recycled material

As well as focusing on sustainability for the sourcing of materials and manufacturing, Evans also considered every element of the process:

  • Generally transport goods by road
  • With 600 units each weighing around 10 tonnes, explored alternative transportation methods to maximise transport carbon savings
  • Determined that using mainly rail would maximise the carbon savings, even accounting for double handling of units
  • The journey involved transporting the goods by road from Evans’ manufacturing facility in Somercotes, Derbyshire to the rail terminus at Toton – 34km, then 200km by rail to site in London

Using this combination of rail and road rather than just road, a CO2 saving of 26g per tonne per km was made. (Source ODA) and in total around 31,200 Kg of CO2 savings made.

ODA Supervisors Quality Excellence Award

In May 2010 Garry McBride,  Chairman of Evans Concrete, was presented with the ODA Supervisors Quality Excellence Award by the ODA for our works on the Olympic Park:

“I would recommend Evans Concrete Products for the award.  Evans is a supplier of precast concrete to Balfour Beatty on SBH Lots 3 and 4.  Based on recommendations, I believe that Evans have picked up additional work on the park – SBH Lots 1, 2 and 6 and the F10 bridge.

The quality of Evan’s precast concrete compared to their competitors on the park has been excellent.  As well as producing quality products, Evans has scored highly on the environmental and sustainability front. They used a large proportion of recycled aggregates in the precast for the temporary bridges and a large number of the units were transported to site from their yard in Derbyshire using rail.”

Olympic Legacy Projects

One of the key aims of London 2012 was to develop a legacy – not only of involvement with sport but also for continued use of all the building projects that had been done. That’s why, even after the games had finished, work continued on key construction projects and Evans Concrete again secured 15 orders involving 600 m3 or 1,260 tonnes with a total of an extra 1300 units.
