Our buildings and transport infrastructure are becoming ever more complex. As a result the process of designing, constructing, running and demolishing them is becoming more complicated too. BIM is a methodology for managing every stage of the lifetime of these assets. But what are the benefits?
The adoption of BIM methods of working and the construction of built assets brings advantages to all project stakeholders. BIM breaks down traditional barriers related to interdisciplinary collaboration, facilitates off-site prefabrication, improves design options, and reduces risk, rework, and cost. BIM also allows for the integration of construction phasing through project scheduling software, automated quantity takeoffs, automated costing based on the integration of materials pricing software packages, and green building analysis, among others.
Listed below are some of the benefits that utilising BIM methodologies brings to us. These benefits are demonstrable and are guaranteed provided BIM is adopted and applied in a methodical manner using intelligence and wisdom.
The benefits of using BIM at the concept, design, construction, operation and demolition stages of a built asset include:
- Imposes best practice on firms and the whole of the supply chain thus increasing standards, improving cash-flow and reducing accidents.
- Improved costing through early acquisition of accurate quantities and manpower estimates.
- Improved scheduling and match digital model with schedule.
- Enhanced data and site security using resilient technology.
- Improved information sharing and more relevant project information available faster to those that need it.
- Reduced requests for information particularly during design stages.
- Performance testing before construction leading to optimised design solutions.
- Simple to amend design and have changes applied parametrically throughout the project.
- Pre construction clash detection means reduced unforeseen changes on site.
- Design history and digital assets stored in databases for future use.
- Faster document production and distribution.
- Shorten construction time.
- Reduced on-site material storage and handling.
- Increased safety for construction staff and the public.
- Improved energy efficiency resulting in energy savings and reduced carbon emissions.
- Improved asset management with easier maintenance, operation, security, change-of-use and demolition.
