The word BEBO® is derived from the German words "BEton BOgen" which stands for concrete arch. The system was developed in 1965 by Swiss engineer Dr. Werner Heierli and first installed in Switzerland in 1966. Ever since it has been used the world over and conforms to various international design standards and codes such US AASHTO, Canadian, British, European, Australian etc. The BEBO® system comprises of precast arches which are transported to the site and installed piece by piece to form a full bridge. The arches are fabricated at a central casting yard using patented moulds. BEBO® offers the world's largest span for precast arches offering spans from 3.6m to 31m.
