Introduction to BIM

Introduction to BIM

Understanding Building Information Modelling (BIM)

  • BIM is a way of handling information about a construction project across the project lifecycle.
  • BIM stands for Building Information Modelling.
  • It uses digital representational models to facilitate the sharing and management of construction and facility information.
  • BIM allows architects, engineers, construction teams and other stakeholders to have coordinated, reliable information about a project.

Benefits of BIM

  • BIM increases efficiency and saves time by enabling better collaboration amongst project participants.
  • It reduces errors and discrepancies in the construction process.
  • BIM’s reliable digital representations of buildings enable accurate project estimation and planning.
  • The technology can model the physical and functional aspects of a building, enhancing the overall design process.
  • BIM provides greater cost predictability, reducing the risk of overspending.

Roles in BIM

  • The BIM Manager is responsible for implementing and managing the BIM protocol.
  • The Architect uses BIM for design visualisation and to identify potential design conflicts.
  • The Engineer uses BIM to perform design simulations and to assess potential impacts.
  • The Contractor uses BIM for estimating costs, planning construction, and controlling project execution.

BIM Processes and Procedures

  • BIM work can follow various stages, known as ‘levels of BIM maturity’, from Level 0 where there is no BIM, through to Level 3 where there is full integration across all project phases.
  • BIM Protocol is a legal framework that defines BIM-related responsibilities and requirements.
  • Common Data Environment (CDE) is a single source of information used for data management during a BIM project.
  • The PAS 1192 series is a set of standards that guide the execution of BIM in the UK.
  • The UK Government mandated the use of Level 2 BIM in all state-funded projects in April 2016.

Impact of BIM on the Construction Industry

  • BIM’s efficiency and accuracy have transformed the way buildings are designed and built.
  • Favorable government policies have fostered the widespread adoption of BIM.
  • The use of BIM has helped in addressing environmental sustainability concerns through improved energy modelling in the construction process.
  • It has ushered in a new era of digital construction, redefining roles and practices within the construction industry.
