Structured communication

Process information is about a clear definition of interactions between the projectpartners. These interactions serve as the basis for communication in Building Information Management.

Insufficient or erroneous communication during construction is the main reason for high downtime costs. For governmental projects – in the Netherlands, for example – the so-called IDM-method has been in use for over 10 years, allowing the consequent structuring and optimisation of communication. This has significantly lowered downtime costs during major and complex construction projects.

ISO standard 'IDM', developed by buildingSMART, stands for Information Delivery Manual and is used in data-exchange, internationally.

Integral contract component

IDM uses a variety of established and scientifically ratified methods – it is both Open Standard and EU-standard. The use of IDM allows for a very project-specific formal, concrete, binding, and personalised communication structure.

Any communication, as defined within IDM, is rated as an agreement and therefore binding for all project participants. IDM based agreements can be an integral contract component and specify legally binding communication channels, information flow, and project documentation.

Based on IDM, any project relevant data supply, responsibilities, rights, roles and processes are described and determined – tasks, jurisdiction, competences, and communication at the interfaces: input, output, participants and relation to other transactions.

Gobar Consulting Group is a co-developer and initiator of IDM.




IDM in practice

Since 2007, numerous civil engineering projects, based on the Dutch contract regulation "UAV89", have been successfully completed with IDM.

In 2008, the use of IDM in infrastructual projects, based on UAV89, became compulsory in the Netherlands to ensure improved formal communication in construction projects. Since then, the number of authorities, organisations, and construction companies using this markedly more efficient form of communication has risen continuously.

  • Precise task distribution (rights and roles)
  • Robust contractual agreements (IDM as contractual component)
  • Creation of efficient and flexible communication structures
  • Continuous access to (partial) results and project progress
  • Documentation of contract negotiations and contract fulfilment
  • Real-time reporting
  • Mirrored and actual contract dossier for contractor and client
  • Support for processes outside the company
