Chapter 14 confronts the difficult, often uncomfortable issues that BIM introduces into construction projects. These issues are not flaws in BIM but rather challenges that become visible when information is transparent and shared. Liability: If a model contains an error that leads to construction defects, who is legally responsible? In traditional workflows, liability is clearer because drawings are signed and sealed. In BIM, multiple parties contribute to shared models.
The chapter discusses contractual approaches: allocating responsibility through the Responsibility Matrix, maintaining version control to track who created which information, and using liability disclaimers for "work in progress" versus "published" model states.
Intellectual property (IP) : A BIM model is a valuable digital asset. Who owns it? The architect who created the model? The engineer who contributed structural data? The contractor who added construction sequencing? The owner who paid for the work? The chapter explains typical IP clauses: the creating party retains ownership of their native model but licenses its use for the project.
Owners often receive ownership of the federated model and COBie data. Insurance: Traditional professional indemnity insurance may not clearly cover BIM activities. The chapter advises speaking with insurers early, documenting BIM workflows, and considering additional coverage for digital data breaches or model corruption.
Data security: BIM models contain sensitive information—building layouts, security systems, equipment values. The chapter covers cybersecurity basics: encrypted CDEs, access controls, audit logs, and procedures for lost or stolen mobile devices.
Standardization vs. flexibility: Too much standardization stifles innovation; too little creates chaos. The authors advise focusing standards on exchange points (what must be interoperable) while allowing flexibility within disciplines.
Legal admissibility: If a dispute goes to court, can BIM data be admitted as evidence? Courts increasingly accept digital evidence, but proper version control, audit trails, and metadata preservation are essential.
