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