15 XRBIA : COMPACT DESIGN

16 XRBIA : DESIGN STANDARDIZATION

17 XRBIA : DELIVERY OBJECTIVES  Conceive  Recognise Opportunity  Visualize (Concept)  Optimize Design  Rationalize through Value Engineering  Improvise in Construction  Complete Project in Time within Cost

18

19 TRADITIONAL DESIGN & PLANNING PROCESS  The architect takes the building through design development before handing the design to the Structural and MEP engineers  There is an iterative process of interaction between the Architect, Structural and MEP Engineers.  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.

22 BIM : 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.

25 BIM : IDEAL PLATFORM FOR XRBIA PROJECT OBJECTIVES  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

40 BIM : CHAMBERS CLASHING WITH FOUNDATIONS

41 BIM : INVERT LEVELS OF CHAMBERS AVAILABLE

42 BIM : TYPICAL TOILET LAYOUT

43 BIM : WALKAROUND Start

44 BIM : 4-D SIMULATION

45

46 BIM : THE CHALLENGES IN IMPLEMENTATION  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

47  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
