Challenge

As official engineering design services provider for the London 2012 Olympic Games, CLM, the consortium responsible for delivery of the Games, had to provide infrastructure on time and on budget, as well as create a valuable legacy for London.

The need for a network of bridges and underpasses was described as threefold: "first, to enable access for the workforce and machines to create the infrastructure and sporting venues in the first place; then, to provide access for the anticipated crowds of Games-time spectators (and athletes); and finally, to provide in legacy a calmer but long-term set of community facilities that would be both functional and environmentally fitting."

Key to the sustainability of the project was the concept of flexible capacity. Several of the permanent footbridges were designed to have temporary decking elements built alongside the permanent structures. These would increase their width for the increased footfall during August 2012 but be easily removed after the event. 

Other structures were designed to be temporary, and to be entirely removed after the event. All of the deck boards and other timber products in the temporary structures were intended to be reused and repurposed after the games.

Solution

Hopping Softwood Products supplied Q-Grip® heavy-duty anti-slip decking for the F02, F03 and F09 temporary footbridges and U06 and U07 underpasses at the London 2012 Olympic Park in Stratford.

To allow ease of removal, Hoppings designed a special bespoke heavy-duty decking board. A fixing clip was inserted into a machined channel in the board. The decking was installed by screwing it through this clip, rather than through the timber itself. To remove the decking it could be unscrewed without suffering damage.

Bridge F03 was a centrepiece structure that crossed the River Lee, connecting the north and south areas of the park. At 56.5m, it is the longest bridge in the park.

Outcome

Q-Grip® decking and other softwood products provided by Hoppings met one of the key elements of brief, as in addition to being manufactured from strength graded and FSC and PEFC certified sustainable sources, they could be easily removed and recycled after the Olympic Games. 

Q-Grip® decking is tested to BS 7976 parts 1 and 2, and provide a 'low potential for slip' under classifications as set out by the UK Slip Resistance Group. It also had to meet a minimum mean corrected Pendulum Test Value of 45 units (prEN13036-4), actually achieving a value of 81. As such the risk of slips and falls to visitors and spectators was greatly reduced during the Games.

The wood in bridge F02 and other temporary bridges has been passed on to Community Wood Recycling, who operate a wood recycling scheme. Some of the material is destined for a community play project in Gravesend. Hoppings' bespoke installation / removal system made this journey easier for BAM Nuttall, who are contracted to convert the Olympic Park after the Games.
