What is BIM?

    Building Information Modelling (BIM) is basically information management using digital modelling, starting from initial building design all the way through its construction process, maintenance, and finally decommissioning. BIM is all about coordination and collaboration between contractors, stake holders, architects, and engineers in a 3D virtual construction environment, and it shares all the related information across these teams.
      BIM allows design and construction teams to coordinate and communicate information about the design and construction at every level of the building process. The shared information remains with the project, right from the beginning of construction till its entire lifetime.

        Key Benefits of using Building Information Modelling

          Applying Building Information Modelling in construction process and holding BIM certification can lead to following key benefits:

            1. It allows visual data collection

              BIM has provided the designers and builders with access to information about project sites that wasn’t accessible before. With better images of the Earth and improved mapping tools, today projects are analysed using aerial imagery, laser scans of infrastructure, and digital elevation. All these together help the builders and designers capture reality more accurately and streamline project preparations. BIM has allowed the designers to benefit from all the compiled input shared in a model and work in a more efficient way.

                2. Reduced Onsite Waste

                  BIM provides a shared model to all the teams working on the project, so there’s less need to duplicate or redraft the drawings for different requirements of project teams. The model not only contains a drawing set but all the information related to the project, allowing each team to annotate and link their intellect to the project. The drawing tools of BIM are faster and more efficient than 2D drawing tools and each of the object is linked to a database. The database helps in calculations such as size and number of windows for quantity take-offs that update automatically with the advancement of the project. This quick and accurate computerized counting of project components saves significant material and labour costs.

                    3. Controlled Project Data and Reduced Uncertainty

                      BIM involves aids such as of auto-saving and project history backup so that the users can be sure that all the work they’ve done so far on the model has been captured and can be accessed any time. The access to version history of the model helps avoid disastrous losses like corruption of files that can interrupt productivity. Using BIM allows the project teams to detect, diagnose, and fix any problem with constructability timely before the construction begins. This can save significant amounts of time and money by preventing the need for any replacement materials.

                        4. Improved Communication and Collaboration Between Teams

                          Communicating and collaborating with models is much easier and more efficient than with drawing sets. It’s because there are various functions that are only possible through digital-model-based workflows. Much of the project management is now being carried out with the help of cloud. Here, there are multiple tools of the project teams to share their complex models and coordinate with their peers to keep them updated. Review and mark-up steps ensure that all the teams have given their input in the evolution of the project and they’re all ready to execute the finalized concept.

                            5. Increased Speed and Efficiency of Processes by Better Sequencing of Steps

                              A model with a well-constructed set of sub-models for each construction phase allows the teams to coordinate the sequencing of steps, crews, and materials for a more efficient and quick construction process. By merging project schedule with BIM model, project managers can watch a project being constructed virtually to ensure that the sequencing of steps within the schedule is accurate and delivering the expected outcome on time.
