Pilot 1:
Barcelona, Spain

  • About

The Spanish pilot is located within a new eco-district being built on the site of a decommissioned Mercedes-Benz car factory and that will include residential, office and university buildings. The pilot is about decontamination of heavy-metal polluted soil in the area and the maximum reuse and recycling of the disassembled structures for the new district being built.

  • The Context

It is set between the Sant Andreu, Bon Pastor and La Sagrera neighbourhoods of Barcelona, one of the most active zones in terms of new construction on the site of old facilities with a past of intense industrial production. The zone is undergoing a profound architectural and demographic transformation and the pilot fits into the city’s Green Deal initiatives.

  • Pilot Objectives
0 %

Аchieve more than 90% of removal of petroleum hydrocarbons and heavy metals from anthropogenic soil on demolition sites

0 %

Increase by more than 40% the recovery of structural members for reuse; and to successfully implement material traceability via wireless sensors

  • Key Activities
  • M6 – M18: development of a BIM-based Digital Twin with advanced features enabling multi-criteria decision-making regarding disassembly and construction protocols
  • M6 – M24: on-site soil decontamination with novel bioremediation and nanobubble water treatment techniques
  • M12 – M36: deployment of near-field communication wireless sensors for material traceability
  • M18 – M42: construction of a prototype structure out of reused and recycled materials from the pilot site
  • Circular Construction Application

Through the use of BIM-based Digital Twins for selective demolition and end use of existing elements, the buildings are converted into material and element databanks and the “building from a stock” principle will be facilitated. By integrating all three pillars of sustainability into the multi-criteria decision-making tools, the pilot guarantees a more sustainable outcome for the construction.

  • Benefits
  • fully safe and decontaminated environment for the residents of the new district while minimizing the impact (i.e., pollution and heavy traffic) during the decontamination process
  • more economic, and sustainable structures through the use of existing materials and elements
  • maintenance of cultural and architectural heritage of the industrial zone by reusing and repurposing the old structures of the site
