ULTIMA Connect At The London Olympics

Cubis systems were involved in the major project of the London 2012 Olympics site and stadium redevelopment.

The implementation of Cubis Access Chambers (in particular, the ULTIMA Connect) to assist with the redevelopment project resulted in huge savings in time and cost. The underground infrastructure was developed in time for the Olympics in 2012, and then updated and reconfigured for the future use of the site two years later.

The site has been massively transformed.

Today, East Bank is a new powerhouse for innovation, creativity and learning on Queen Elizabeth Olympic Park. It is a unique collaboration between world-leading universities, arts and culture institution that opens up opportunities for everyone who visits, lives and works in East London. The industrial land has been replaced with landscaped greenery; while the rivers and canals, previously derelict, are now dotted with tour boats and swan-shaped paddle boats.

Cubis supplied large chambers for turning of large high-voltage power cables in the build in time for the 2012 Olympic Games.

The chambers were designed and manufactured using the original ‘cut and bolt’ system to order, the largest being 6m x 3m x 3m (internal dimensions).

Two years after the games finished, the site was being re-configured for future use, which meant upgrading and diverting the buried infrastructure on site. Cubis were asked to supply a solution for two chambers that would be able to be retrofitted over the existing cable banks.

Olympic Stadium Redevelopment

In order to meet the criteria, Cubis supplied the ULTIMA Connect system in flat-pack format for this project. Thanks to the component design, the chambers could be fabricated on site to build around the ducts. This was done by forming two ‘C shape’ chambers around the duct bank until it reached the depth that allowed the chamber to be built normally over the top.


Each installation took less than a day to complete, including the assembly and backfill. This was significantly faster than alternatives, while offering a flexible solution for benching over existing  services and creating duct entries.

The redevelopment of the London Olympic East site now features a new tech cluster of start-ups, corporations, universities, venture capital investors and a huge new data centre. The buildings contain more than a million square feet of redeveloped space that was once home to BT Sport and other broadcasters during and after the London Olympics.

The redevelopment of the site by Laing O’Rourke Group for future use meant the upgrade of more high and low-voltage power supplies on site. Cubis were asked to supply a chamber system solution that could be quickly installed without the need for expensive trades. The use of the STAKKAbox™ ULTIMA Connect offered the customer the flexibility to build on site to bespoke dimensions. The flexibility of the flat-pack connect system was highlighted when the customers’ needs changed at the last minute due to the conditions on site with limited access. The connect system was able to be built and altered onsite for a quick turnaround for the customer and this resulted in the installation of 1 x 5m x 2m x 1.2 deep chamber and 1 x 2m x 2m x 0.9m deep chamber by two operatives in less than 3½ hours.

The significantly faster install time compared to alternatives lead to the order of more chambers by the contractor for further works.

Cubis Access Chambers

STAKKAbox™ chambers are significantly faster to install than conventional alternatives, with complete installations typically taking under one hour. This results in reduced costs for the installer and significant time saving. No specialist equipment or plant is required in order to install an access chamber and there is no need for specialist box builders. With flexible installation, cubis access chambers can be adapted to suit on-site conditions with standard tools to build over existing networks.
