What is BIM or Building Information Modelling?
Building Information Modeling (BIM) describes the method of advancement and use of a computerized model to simulate the planning, design, construction and operation of a building or facility. The resulting model or a Building Information Model, is a data-rich, object-oriented, rational and parametric digital representation of the facility containing both graphical and non-graphical information in a Common Data Environment (CDE) (a shared repository for digital project information).
A Building Information Model characterizes the geometry, spatial relationships, geographic information, quantities and properties of building elements, cost estimates, material inventories and project schedule. Therefore, Building Information Modelling BIM provides all information associated to the building or facility, including its physical/functional characteristics and project life cycle information, in a series of “Smart objects”.
BIM Applications in Construction
- Visualization – 3D renderings give a detailed idea of the end product rather than imagining descriptions and sketches.
- Fabrication/shop drawings – Generating shop drawings for different building systems becomes easier and more efficient after BIM.
- Code reviews – Different departments and other officials may use these models for their review of building projects.
- Forensic analysis – BIM can be easily integrated to graphically demonstrate potential failures, leaks, clashes, evacuation plans, etc.
- Facilities management – BIM can be used for renovations, space planning, and maintenance operations.
- Cost estimating – BIM software(s) have built-in cost estimating features. Material quantities are automatically obtained and adjusted when any changes are made in the model.
- Construction sequencing – BIM can be efficiently used to create material ordering, fabrication, and delivery schedules for all building components.
- Conflict and Clash detection – BIM helps in speeding up projects by identifying clashes between several models during the design stage itself, helping architects and contractors eliminate chances of multi-level design changes which can result into budget overshoot and delay in project completion.
Why do you need BIM? Benefits of BIM in construction.
- AGILE & Efficient Communication – Its perfect for collaboration. Digital BIM models allows easy sharing and collaboration among the stakeholders to permit a symbiotic approach. With cloud-based tools such as Autodesk’s BIM 360, BIM collaboration can seamlessly occur across all disciplines within the project.
- Model-based Construction Cost Estimation – Cost estimation model (5D BIM) in the planning stage is more effective and the use of BIM tools such as Revit and BIM 360 Docs automates the time-consuming task of quantifying and implementing costs, allowing estimators to focus on higher value factors, such as identifying construction assemblies and factoring risks. This controls the whole-life costs, performance is more foreseen, and lifecycle costs are better understood.
- Visualize project in Planning or Preconstruction stage – BIM tools enable visualization and planning of projects in the Preconstruction stage for a better design. 3D visualizations and simulations help to experience the design even before construction starts and accordingly make changes to optimize the design.
- Clash Detection – Tools like Autodesk’s BIM 360 Glue facilitate in detecting any MEP, internal, or external clashes even before construction begins with automated clash detection and reduces scope for any rework to be done.
- Enhanced Scheduling – BIM facilitates synchronous design and documentation as well as easy alteration or modification of documentation to adapt to any new site conditions. The improved collaboration & communication allows meticulous planning resulting in on-time project delivery.
- Enhanced Productivity with Prefabrication and Modular Construction – BIM can be applied to spontaneously generate production drawings or databases for manufacturing purpose allowing increased use of prefabrication and modular construction technology. The detailed production models can later be prefabricated off-site in a controlled environment thereby increasing efficiency, decreasing waste, and reducing labor & material cost.
- Mitigating Risk for better safety – BIM allows improved construction safety by analyzing and recognizing hazards and uncertainties beforehand. Safety evaluations and visual risk analysis secure safe workflow throughout the course of construction process. Taking advantage of BIM allows better coordination with contractors and results in reduced tender risk premiums, reduced cost of insurance, lower number of generic transcriptions, and lower risk of claims.
- Organize Facility Management – BIM allows an accurate and continuous digital checklist of building information for managing facilities and renovators for the entire lifecycle. With tools like Autodesk’s BIM 360 Ops, contractors can modify building handover by connecting BIM data generated during design and construction to building operations.
The Future is BIM-shaped
BIM Benefits for AEC industry
All of the professionals who are a part of the design and construction industry get advantages from BIM. Who gets the maximum value out of it?
Architects – BIM started to evolve with architects with its emerging value in the design phases. Most in the design community, along with many contractors (43%) and owners (41%), say that architects experience a high level of value.
Structural Engineers – With elements as steel columns, beams and trusses that are frequently modeled by users of Structural community, structural engineers can reap a high level of value from BIM. Contractors are most probable (47%) to see structural engineers realizing significant benefits.
Construction Managers and General Contractors – Construction involves a huge amount of cost and any rework would further add to the expenses. Owners are the most likely (57%) to see a Construction Managers or General Contractors gaining high value on a project, most likely because of the savings from avoiding any rework.
Fabricators – BIM reduces conflicts and facilitates clash detection to optimize building plans. Accurate fabrication of materials reduces waste while the pre-assembly can save time. Contractors (56%) are far more likely to see fabricators experiencing a higher value than architects (23%), engineers (38%) or owners (30%).
MEP Engineers – BIM has an array of opportunities MEP coordination. It’s convenient to model larger elements such as duct systems and air handlers, while smaller components such as electrical switches and outlets might prove more challenging. Notably, very few engineers (22%) collectively see MEP engineers reaping high value. Nearly half of contractors (45%) believe MEP engineers see significant value.
Stanford University Center for Integrated Facilities Engineering (CIFE) study based on 32 major projects using BIM indicates benefits such as:
- Up to 40% elimination of unbudgeted change
- cost estimation accuracy within 3%
- Up to 80% reduction in time taken to generate a cost estimate
- Saves up to 10% of the contract value through clash detections
- Up to 7% reduction in project time
Why is BIM important?
Building Information Modeling (BIM) is rising as an innovative way to manage project, BIM expedites collaboration within stakeholders, which will lead to improved profitability, reduced costs, better time management, and improved client relationship. BIM not only allows design and construction teams to work more efficiently, but it allows them to obtain the data they generate during the process to gain from operational and maintenance activities.
As per the UN, the world’s population will be around 9.7 billion by 2050. The global AEC industry must look for intelligent, productive and progressive ways to design and build not just as a means to keep up with global demand but to help create spaces that are smarter and more flexible.
BIM represents a new paradigm within AEC, one that encourages integration of the roles of all stakeholders. This is why BIM mandates are increasing across the globe.
