According to the US National Building Information Model Standard Project Committee: “Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition (NBIMS-US, 2016).”
BIM is used to generate and manage the physical and functional characteristics of a building through digital representations. BIM allows companies, right from the planning stage to the maintenance of various buildings and infrastructure, to be able to make well-grounded decisions from building construction to building demolition. Engineers are also able to create models on a computer and also transform drawings, blueprints, and plans to BIM models. These realistic models are clean with rich details. They reference each aspect of the building.
BIM allows the entire project team to work in cohesion while providing timely updates as and when required. Construction managers find BIM models very effective in visualizing different scenarios in planning the project. This final model can then be shared with the clients and other stakeholders.
Since this visual representation is vital, it goes without saying that the data provided to create this visualization has to be perfect. Whatever model is created is dependent on the data.
Construction Management using BIM
BIM can be considered a blessing as it assists engineers in more ways than one. It helps them spot out the issues right at the beginning. Issues like budget, manpower, etc. can be planned following the BIM model and any challenge present is brought up before construction begins.
BIM helps reduce construction costs and makes construction more efficient. Simulating real-life conditions on the model helps architects, engineers and those in charge of construction to ensure that the building meets all the compliance standards, like energy efficiency, the material used, lighting, etc. Optimizing the conditions before construction saves a lot in terms of cost and time.
Another major benefit of BIM is in clash detection and resolution. The models help to visualize each aspect of the infrastructure so it’s easy for contractors to pinpoint likely areas of trouble – like a clash in plumbing and ventilation. If such clashes are detected early on, the design can be updated to resolve these clashes, saving time and money once again.
As BIM is being used more widely, the data being collected to create the BIM models is also increasing. More data means that there is more precision in the model to make construction more easy and effective.
Overall, the advantages of BIM in construction are:
As more and more time and the cost is saved by using BIM in construction, and the ability for the engineers to bring their offices to the construction site (BIM tools and the cloud help them access and share the models and any changes on-site easily) there are more advantages for the contractors. They can better understand design intent, construct quality buildings. get more work, and execute more and more quality projects.
