The complete name of RDC (Research and Development Concretes) gives a clue of its origins. In 2010 two of its founders (Juan Ángel López and Esteban Camacho) were actively researching at the Universitat Politècnica de València the design of UHPC mixtures and the possibilities of UHPC precast structures with it. There they met Hugo Coll, an associate professor who found the possibility of using it in a work where he was involved, the footbridge of the Oveja’s ravine, in Alicante (Spain). Juan Ángel López was its designer, and a year later it became a reality, being the first UHPC structure in Spain and the first world truss footbridge made only with UHPC. The 44-m span structure was precast at PREVALESA, which technical director was Fernando Galán. These four persons understood during this project that they could be a valuable and complementary team to boost the use of this efficient material in different sectors. Soon they collaborated again to produce a second footbridge over the V-21 motorway, in Puzol, with a total length exceeding the 100 m. The successful experiences proved that the cooperation had vocation of becoming a business, so in 2015 the team decided to found RDC. Between 2015 and 2018 RDC cooperated with different precast companies to make real their innovative designs, floating the first UHPC raft for aquaculture, installing ultra-thin UHPC stairs or building the first UHPC bridge in Spain. In 2018, RDC founders felt that they needed their own precasting facilities to release all their innovation potential and being less dependent on third parties. Thus, in September of 2018 they created PREFFOR, a company specialized in the production of precast UHPC elements using Formex^®. Currently, the synergies between both companies are significant, as RDC can provide a market-oriented approach based on PREFFOR successful experiences, and PREFFOR feeds from the knowledge gained by RDC over the years.
