After review of cost, the owner initiates changes and the whole design process is repeated The entire design is then co-ordinated, resulting in more iterative stages in design The Working drawings are handed to the contractor, who also goes through a process of review. Clashes, constraints are observed at site, which calls for designer intervention to resolve issues. All this results in constant communication between all the team members. TRADITIONAL DESIGN & PLANNING PROCESS TRADITIONAL DESIGN & PLANNING PROCESS The term “BIM” is used to describe the end product as well as the process of the project delivery. The design team uses BIM as a work process and means of communicating with one another, the end product of which is the model. BIM is a virtual process that encompasses all aspects, disciplines, and systems of a building within a single, virtual model, allowing all design members to collaborate accurately and efficiently. In the BIM process, team members are constantly refining and adjusting their portions according to owner preferences, systems compatibility, to ensure the model accurately represents the design intent at all times The model itself is used to calculate materials take-offs for cost estimation, as well as for clash detection. BIM : DESIGN & PLANNING PROCESS BIM : DESIGN & PLANNING PROCESS The Affordable Housing segment cannot afford cost or time over-runs The XRBIA Affordable Housing project is productized in nature to be adopted on a Pan-India basis BIM provides the platform to share the building database across multiple projects Cost Implications can be effectively monitored at every stage Good for construction drawings can be auto generated from the BIM model with minimal inputs Labour can be trained on the construction methodology using the visual BIM model, resulting in increased productivity and reduced reworking Visual display of progress of work of all distributed sites at a central location for easy monitoring BIM : IDEAL PLATFORM FOR XRBIA PROJECT OBJECTIVES BIM : XRBIA HINJEWADI EXPERIENCE BIM : XRBIA HINJEWADI EXPERIENCE BIM : BUILDING MODEL BIM : BUILDING SHELL BIM : 1 BHK UNIT MODEL BIM : INTERNALS OF THE BUILDING BIM : FOUNDATION AND STUB COLUMNS BIM : PLINTH BIM : GROUND FLOOR BIM : EXCAVATION VOLUME, SUB-STRUCTURE, STILT BIM : SUB-STRUCTURE, STILT WITH PLUMBING PIPE STACK BIM : PLUMBING PIPE CONNECTIONS IN THE STILT BIM : PLUMBING PIPES WITH CLEARANCE HEIGHTS BIM : CHAMBERS CLASHING WITH FOUNDATIONS BIM : INVERT LEVELS OF CHAMBERS AVAILABLE BIM : TYPICAL TOILET LAYOUT Start BIM : WALKAROUND BIM : 4-D SIMULATION Inculcating discipline in approach in all team members participating in the design and planning process Changing the “Design As You Build” mindset amongst architects and engineers Ensuring that all details are provided from the outset, and realize that BIM is virtual construction process Realizing that the BIM Modeler needs to be an integral part of the Design and Engineering team, and must be on board at the start of the Design and Engineering stage itself. Defining the process to verify the accuracy of the model created Defining the process of co-ordination, clash detection and its removal BIM : THE CHALLENGES IN IMPLEMENTATION Designing the modeling process to ensure that the file sizes remain manageable, yet a fully integrated view can be easily generated and model is amenable to frequent changes in design Process of generating accurate 2-D drawings from the BIM Model, with details adequate enough to be used as working drawings Accurately defining project schedules so that these can be seamlessly integrated with the BIM 4-D simulation Defining a suitable Work Breakdown structure for on-line Cost generation from BIM, 5-D stage Defining parameters related to manufactures data to be linked to BIM elements BIM : THE CHALLENGES IN IMPLEMENTATION CONCLUSION
