Low-carbon stadium a showcase for engineering

A case study in innovation, collaboration and adding social value, the Olympic Stadium captured the pride of a nation.

We were proud to be selected as the main contractor for London's Olympic Stadium.

We were eager to create a venue that would not only capture the world’s attention, but would showcase innovative design, sustainability, engineering excellence and collaborative working.

Our ability to ‘embrace the temporary’ was critical in delivering an 80,000-seat stadium, that could be turned into a 25,000-seat athletics venue after 2012.

The result was a lean, efficient and highly accessible venue, bringing spectators closer to the action than in previous Games.

The venue's compact size reduced costs, accelerated programme and helped meet our client’s sustainability aspirations. We sped up construction through creative design and developed an alternative roof solution which reduced the amount of steel required.

Delivered early, under budget and with an exemplary safety record, the stadium showcases the power of integrated working and leaves an inspiring legacy.

Design efficiency

Through applying smart design, we reduced the time from end-concept to start of construction by 12 months. This was achieved through creating a repetitive design, which maximised prefabrication, minimised components and simplified connections.

Our project team’s alternative proposal for a lightweight cable net roof was the most sustainable option, using only half the steel of a standard cantilever design.

Raising the roof

Erecting the cable net roof and sports lighting towers were major project challenges. The entire process was designed to minimise work at height.

Precision fabrication and installation ensured the 28 steel sections forming the roof’s outer compression truss fitted perfectly.

Then we laid the inner tension ring on a scaffold, which was custom-made by our in-house design team to run around the inside of the bowl. From here, the ring was lifted 40m into place using computer-controlled jacks.

The 14 sports lighting towers were constructed on the playing field. Equipment and circuits were tested at ground level before the rigs were lifted onto the tension ring and secured with a secondary system of cables.

With each tower weighing 35 tonnes, their combined weight on the edge of a cable net roof was a first in stadium design.
