What is BIM?
Building Information Modelling (BIM) is a method for optimizing the design, execution and operation of building structures. In which we design intelligent three-dimensional model and enables document management, coordination and simulation using data-rich three-dimensional models and can be enhanced by adding further information, such as on time, costs, utilization. It is an easy viewing of designs facilitates better and more well-informed decision making and consultation and a total access to the information, with models stored in a cloud server.
Different BIM Dimensions
BIM has different dimensions (3D , 4D, 5D, 6D, and latest 7D) of workflow according to provide information and data input in to 3D model of buildings.
- 3D BIM – Basic 3- dimensional model with contain graphical and non-graphical data of model.
- 4D BIM -This dimension is provide the “Time” information. this information about execution time of project.
- 5D BIM – In this dimension provide the information about capital “Cost” of entire project.
- 6D BIM – This dimension provide the information of “sustainability”. This means durability to sustain the project.
- 7D BIM – In this dimensions about Management and maintenance and provide facilities
In India BIM is also known as with different keyword VDC: Virtual Design and Construction.
What is Use of BIM?
BIM is used to design the building information in 2D and 3d model and document building and infrastructure designs. BIM technique is a information – rich data providing technology work methodology that is based on the creation of a 3D model contains every information of a building. The model can be used for analysis to explore design options and to create visualizations and walk-through that help understand what the building will look like before it’s built. Resolving coordination issues at a very early stage in the project, results in significant savings of time, cost and energy. With enhanced scheduling, estimating and facility management abilities, a whole new world of opportunity for BIM has opened. The BIM model is used to generate the construction documentation which is used by builders and engineer on construction sites. BIM not only allows to design and construction also helps to gain more insights earlier in the process to meet your clients’ requirements and deliver projects with improved quality and efficiency.
Benefits of BIM
The using of BIM to improve the productivity and reduce the construction cost as well as early and easily completion of project without any risk. The application of BIM we can visualize as real the whole project at every step of lifecycle of BIM with walk-through navigation and remove the defect before execution in real. Following are some noticeable benefits of implementation of BIM –
- Reduced time for designing and documenting
- Detection of Potential Major Clashes of various Construction Components
- Improve the collaboration between different discipline team members
- Ability to Explore Design Options in full Detail
- Ability to Extract Material Quantities for Estimating Purposes
- Ability to create construction sequencing to improve site and construction logistics planning.
The process of BIM is based on layer (from layer 0- layer 3 ) system to providing information about project. level 1 and level 2 consist of nearly about 90% data and these are further categories in dimensions 3D, 4D, 5D, 6D, and 7D. These BIM dimensions provide the information about the project at different stage and different category to execution of project, these process of execution are called life-cycle. BIM lifecycle include the process of –
Overview with some roughly(primary survey) and visualizing Information of project planning by co-relate reality and real-world data to generate models of the existing built and natural environment.
BIM model can act as an integrator, being the central design tool, and using analytical capabilities in different engineering disciplines.
During this phase, fabrication begins using BIM specifications. Project construction the constructor and the other team member can exercise greater control over the work, minimizing risks, and facilitating the tasks of programming, scheduling and monitoring the execution times.
BIM data carries over the data information which help to operations and maintenance. BIM integrates all the information related to the operation of the infrastructure, such as the actions in valves and gates, flows discharged by spillways or outlet elements, thresholds established in operation rules and emergency action plans, etc.
- Maintain: BIM facilitates the Programming of activities, and establishing, for each task, the resources and necessary means, and the procedures or instructions.
BIM is Used in Industries
Architects use BIM to evaluate design options and automatically generate accurate 2D drawings from the 3D model. BIM helps architects minimize errors, improve building performance and omissions in documents, reduce rework, and decrease design time Make better design decisions, , collaborate more effectively throughout the project lifecycle of a project, automating processes such as programming, conceptual design, detailed design, analysis, documentation, manufacturing, construction logistics, operation and maintenance, renovation and/or demolition.
BIM help for civil engineer to decision making information. Also helps to check load and failure on component which helps to reduces risks and the error. BIM also helps to improves the process of construction to early execution with better quality. Also providing data-driven assurance that projects can be delivered on schedule and on budget.
In the part of construction and management of project, execute and maintain the building information and then handover to the company’s management. BIM data carries over the information to plan and execute more efficiently to support making informed decision and more predictable outcomes. This facilitates collaboration even after the project has finished, reducing risk and staying true to the design aspects.
With the help of BIM, MEP Engineers can easily access the design data even from complex design, from the architectural model. BIM allows to fast and efficient workflow in real – time.
Building Information Modeling (BIM) helps structural engineers to enhance the productivity and optimize designs, improve collaboration, and deliver projects in real time. BIM for structural engineer are productivity, coordination and consistency of data, and improved visualization and simulation of problems and situations
