Building Information Modelling (BIM) is the future

Building Information Modelling

Building Information Modelling (BIM) is a generic name for the digital representation of the building process using new and progressive technologies in the architectural, building and engineering sector. Various digital tools and technologies, involving the generation and management of digital representations of physical and functional characteristics of places, are used.  This information is used to make informed decisions regarding a built asset in the construction industry.  It is a progression from traditional architectural design which was largely reliant upon two-dimensional technical drawings (plans, elevations, sections, etc).

BIM is used throughout the lifespan of the mega-project.  From planning, design, construction & operation and maintenance of the structure. BIM is also used across all sectors of infrastructure from water, energy, oil & gas, mining, roads and bridges, railway, renewable energy to name a few.

History of BIM:

The term ‘Building Information Model’ first appeared in a 1992 paper by G.A. van Nederveen and F. P. Tolman. Autodesk pioneered BIM software in the early 2000s.

Building information modelling is often associated with Industry Foundation Classes (IFCs) and aecXML – data structures for representing information – developed by. IFC is recognised by the ISO and has been an official international standard, ISO 16739, since 2013.

In January 2019, ISO published the first two parts of ISO 19650, providing a framework for building information modelling, based on process standards developed in the United Kingdom. UK BS and PAS 1192 specifications form the basis of further parts of the ISO 19650 series, with parts on asset management (Part 3) and security management (Part 5) published in 2020.

ISO 19650:2019 defines BIM as: Use of a shared digital representation of a built asset to facilitate design, construction and operation processes to form a reliable basis for decisions.

The IEC/ISO 81346 series for reference designation has published 81346-12:2018 also known as RDS-CW (Reference Designation System for Construction Works). The use of RDS-CW offers the prospect of integrating BIM with complementary international standards based classification systems being developed for the Power Plant sector.

What are the Benefits of using BIM?

  • Improves the management of construction information – time (4D BIM), cost (5D BIM), manufacturers’ details, sustainability, maintenance information, asset management.
  • Promotes continuous communication with construction professionals, allowing for concurrent project management.
  • Utilising computer models and iteration simulation.
  • Scenario planning.
  • Environment impact predictions.
  • Provide real time information and analysis of a project
  • Evaluation of an infrastructure projects in important detail.
  • Enables a virtual information model to be shared by the design team architects, landscape architects, surveyors, civil, structural and building services engineers,  main contractor, subcontractors, and the owner/operator.
  • Each professional adds discipline specific data to the model for better project management.
