Ten steps to BIM
BIM – Building Information Modelling – is a co-ordinated set of processes, supported by technology, that add value by creating, managing and sharing the properties of an asset throughout its lifecycle. BIM incorporates data – physical, commercial, environmental, and operational – on every element of a development’s design.
- Better outcomes through collaboration All project partners – different design disciplines, the customer, contractor, specialists and suppliers – use a single, shared 3D model, cultivating collaborative working relationships. This ensures everyone is focused on achieving best value, from project inception to eventual decommissioning.
- Enhanced performance – BIM makes possible swift and accurate comparison of different design options, enabling development of more efficient, cost-effective and sustainable solutions.
- Optimised solutions – Through deployment of new generative modelling technologies, solutions can be cost-effectively optimised against agreed parameters.
- Greater predictability – Projects can be visualised at an early stage, giving owners and operators a clear idea of design intent and allowing them to modify the design to achieve the outcomes they want. In advance of construction, BIM also enables the project team to ‘build’ the project in a virtual environment, rehearsing complex procedures, optimising temporary works designs and planning procurement of materials, equipment and manpower.
- Faster project delivery – Time savings, up to 50%, can be achieved by agreeing the design concept early in project development to eliminate late stage design changes; using standard design elements when practicable; resolving complex construction details before the project goes on site; avoiding clashes; taking advantage of intelligence and automation within the model to check design integrity and estimate quantities; producing fabrication and construction drawings from the model; and using data to control construction equipment.
- Reduced safety risk – Crowd behaviour and fire modelling capability enable designs to be optimised for public safety. Asset managers can use the 3D model to enhance operational safety. Contractors can minimise construction risks by reviewing complex details or procedures before going on site.
- Fits first time – Integrating multidisciplinary design inputs using a single 3D model allows interface issues to be identified and resolved in advance of construction, eliminating the cost and time impacts of redesign. The model also enables new and existing assets to be integrated seamlessly.
- Reduced waste – Exact quantity take-offs mean that materials are not over-ordered. Precise programme scheduling enables just-in-time delivery of materials and equipment, reducing potential for damage. Use of BIM for automated fabrication of equipment and components enables more efficient materials handling and waste recovery.
- Whole life asset management – BIM models contain product information that assists with commissioning, operation and maintenance activities – for example sequences for start-up and shut-down, interactive 3D diagrams showing how to take apart and reassemble equipment items and specifications allowing replacement parts to be ordered.
- Continual improvement – Members of the project team can feed back information about the performance of processes and items of equipment, driving improvements on subsequent projects.
