The Municipal Institute of Housing and Renovation of Barcelona (IMHAB) is promoting a new construction system that speeds up the building process: industrialised housing. By using this system, the public housing stock can grow much faster and citizens can have faster access to housing. Some examples of how this system works could be seen at the IMHAB stand during the last edition of Construmat, held in Barcelona between 21 and 23 May.
The single tender model for the project and works is used to reduce construction times. Unlike the traditional system, in this collaborative system the construction company and the architectural firm work together from the beginning of the project, and some of the processes are carried out in parallel in the factory and are taken to the site once they are ready.
Significant reduction in construction times
How does this work in practice? Based on real cases of buildings promoted by IMHAB, those that follow the traditional method and tendering are delivered on average after about five and a half years. On the other hand, those using the collaborative and industrialised system are completed in three and a half years.
These figures were given by Joan Carles Melero, IMHAB’s technical services manager, in a presentation at Construmat, the reference fair for the construction and renovation world, which was held at the Gran Via venue of Fira de Barcelona and featured all the most important developments in the sector.
In this year’s edition, IMHAB was present with a stand dedicated to four aspects: industrialised housing, land mobilisation for social housing, quality and efficiency, and renovation. The stand also featured models of some of the winning projects and an immersive video about the work that IMHAB has been doing for almost 100 years to increase Barcelona’s public housing stock in an efficient and sustainable way.
Exhibition on industrialised housing
In order for citizens to learn more about the industrialised housing model, IMHAB has created a itinerant exhibition that can currently be seen in the lobby of the Escola del Treball of the Escola Industrial until the end of June (Comte d’Urgell street, 187, building 11, from 8 am to 2 pm and from 4 pm to 10 pm).
