BIMCHAIN puts Blockchain at the heart of BIM. Our mission is to empower Stakeholders with trusted data for better control of their building projects. By plugging BIMCHAIN into BIM processes we deliver proofs of contributions that allow all parties to be accountable for the data they share and limit their liability. An integrated solution that provides undeniable traceability, removes the need for paper and makes BIM data contractual; creating a secure collaboration that will ultimately bring the efficiency gains, BIM promises.
