Ingenuity and innovation

The BBR story began during the Second World War, when materials were in short supply – the import of steel was difficult and, with reduced energy availability, cement was a precious commodity.

Exploring alternatives

Determined to use their ingenuity to overcome these limitations, the three BBR founders – Max Birkenmaier, Antonio Brandestini and Mirko Robin Ros - explored the savings to be made by using pretensioned reinforcement for concrete support girders.

Complete range

During the 1950s and 1960s, BBR developed a complete range of prestressing and post-tensioning systems, ground anchors and stay cable anchorages, to cover all structural engineering applications.

Birth of the BBR Network

From the very early days, construction engineering firms around the world were keen to participate in the success of BBR’s designs and technologies. It was recognized that not only a license to use the designs and sell the specialist equipment was necessary, but also that an effective process for knowledge transfer was needed to support best practice in the use and especially installation of BBR technologies. Thus, the BBR Network was born and today, it operates in over 50 different countries.

International success

Since the early applications more than 60 years ago, there have been many stories to tell of BBR successes and innovation. BBR technology has been applied to thousands of projects around the world – including more than 400 stay cable structures. And the BBR success story will continue with yet more innovative new technology and projects – always staying one step ahead!
