Considering how to introduce this technology in the field of construction will involve a new dynamic linkage of various companies and actors. A peer-to-peer, or hierarchical, relationship is established where due to the large volume of information the use of other technology is required. The emergence of the blockchain provides a trusted infrastructure that allows information management to be perpetuated for the life of the building, distributed and accessible, and maintains traceability of who, when and how information is generated.

When using building information modelling (BIM), which assumes a centralised building information model, there is a place for blockchain to bring integrity, security and transparency to the method. With blockchain in the design and construction phases, it will be possible to improve the reliability of the data, the work carried out and the material quantities recorded. And later, in the maintenance phase of the building, it is also an effective tool while maintaining the privacy of the information, since it will be possible to guarantee the secure storage of the data.

The complexity of our sector, the specialisation, the fragmentation of professions and processes, the large volume of information to be exchanged generate more and more complex documents. In order to have a correct traceability of information, and to avoid disputes and litigation between its agents, this is a key aspect. The great contribution of blockchain in construction will be the introduction of Smart Contracts.

A lot of changes, a lot of innovation. Something we need to integrate as soon as possible.
