- 2. 2 BIM is a process of generating and managing building data during its complete lifecycle, from conceptual design through operation of the building Building information modeling (BIM) is an integrated workflow that enables architects, engineers, and builders to explore a project digitally before it is built. BIM is Evolution not Revolution The creation and use of coordinated, internally consistent, computable information about a building project in BIM is a modern technology and associated set of processes to produce, communicate, and analyze ‘building models’….. •‘Digital representations’ of the building components that follow parametric rules, which can be manipulated in an intelligent fashion •Carry ‘computable graphic and non‐redundant data attributes’ which are consistent, coordinated which can be viewed WHAT IS BIM ?

- 8. CONTROLLING RISK BY ENHANCING AGILITY Virtually all construction projects encounter unforeseen circumstances with the potential to delay the project schedule and rapidly increase project cost ENHANCED DECISION MAKING Customers must make any decision during the design and construction phase of their project and effective communication is necessary for success. Reliably presenting customers with accurate information is critical to ensure those decisions are well informed and timely. IMPROVING QUALITY WITH DIGITAL PROTOTYPING Because each construction project is unique problem with constructability and detailing are common. 2 1 3

- 26. Status in India 26 BIM is gaining popularity amongst professionals within the Indian built environment sector BIM enjoys maximum popularity among experienced professionals since they have a better appreciation of the value proposition of BIM. BIM is more popular in large organisations, with a large strength of technical staff, hinting that BIM implementation is more beneficial in large and complex projects

Software too Expensive 24% No technical Expertise 28% Owners not requested 24% Not familier with the technology 24% Reasons for not using BIM in India BIM is still in its infancy stage in India Still has not reached a stage where users can boast about the cost savings for a project due to BIM implementation because a majority of BIM users in India have not seen a full cycle of BIM implementation for their projects Organizations remain sceptical about BIM implementation and its perceived benefits
- 28. Solar Study • Green BIM • Utilization of BIM helps make buildings more sustainable • Example: sunlight and temperature control • Mockups • A headset would allow one to walk into an empty room and get a virtual feel of what the room will look like upon completion FUTURE POSSIBILITIES OF BIM
- 29. 29 BIM and Sustainable Design BIM technologies provide immediate insight in how design decisions impact building performance, while BIM processes encourage an integrated design approach – a critical strategy for making projects greener. Also green design and construction rely on improving building performance. BIM models can also give more information to product manufacturers, which can eliminate waste. Using BIM, extended design teams can visualize design changes and simulate how various scenarios will affect building performance. With this direct feedback, designers can analyze alternatives that will improve energy efficiency, optimize for natural light and ventilation, evaluate viability and placement of solar panels, and more
- 30. PRODUCTIVITY GAINS Productivity gain is one of the major benefits of using BIM and is the top metric organizations expect to improve when they adopt the technology. Primarily, BIM realizes this gain through its ability to: minimize project management foster communication and co- ordination identify errors early reduce rework reduce costs improve quality. DESIGN As a lifecycle model, BIM begins in the early stages of a project. Designers are likely to benefit from fundamental changes to the design process and the greater certainty between design intent and the final construction and operation of the building. Benefits of BIM
- 31. •Flow of data •Improper schedule of work •Cost estimate is tedious and not accurate •Digitalization of data is less •Clash detection becomes very difficult to notice •Reinforcement details in junctions •Energy analysis •Complexity of software used for BIM •Cost of software •Lack of BIM knowledge in India •BIM course is only available abroad •The computer system running these software needs high end specifications Drawbacks/Problems faced when BIM is not used

- 33. BIM will then enable the most efficient delivery of a sustainable development CONCLUSION The socio-economic and environmental aspects can both be addressed by simply re-thinking the construction process including the sourcing of recycled and reclaimed materials where possible However, BIM provides a better platform to address the technical issues. The benefits such as increased communication, design integration, lean construction, reduced waste, paperless documentation, clash detection, costing, programming, simulation and modelling are far superior to that of CAD. •BIM is promising and more advantageous compared to the traditional process, but still it has several setbacks as the technology is still in primitive stage. •A significant amount of development is to be done in information flow and interoperability of the software. •Additional training material is to be provided with software to learn the complicated features •In India, universities should start teaching BIM as an academic course to make the people perfect in this field. 33
