WHAT IS BIM ?
WHAT ARE ITS BENEFITS TO THE CONSTRUCTION
INDUSTRY?
BIM/BIMsBuilding Information Modelling (BIM) – digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolitionBuilding Information Models (BIMs) – the output of the BIM process; digital files that describe every aspect of the project that support decision-making throughout a project cycle

BIM Objects
Vague and undefined, generic or product-specific, solid shapes or void-space oriented (like the shape of a room), that carry their geometry, relations and attributes; also parameters and relations to other objects
BIM Design Tools
Extract different views from a model

THE 5D MODEL AND VARIOUS DIMENSIONS
5-D Functionality can integrate design, cost, and schedule in 3-D output.Building Information Modeling (BIM) is a digital representative of physical and
functional characteristics of a project, forming a reliable basis for decisions during the project’s life cycle
Element of a 3-D model are linked to the execution schedule
Information that can be embedded in 3-D model:• Geometry• Spatial data (from
geographic information system/lidar)
• Specifications• Aesthetics ( eg, Color )• Thermal properties• Acoustic properties
Element of a 3-D model are used to develop budget and linked to cost heads

• Existing Conditions Models
• Laser scanning• Ground
Penetration• Radar (GPR)
conversions• Safety & Logistic
Models• Animations,
Rendering, walkthrough
• BIM driven prefabrication
• Laser accurate BIM driven layout
SCHEDULING • Project phasing
Simulations• Lean Scheduling• Last Planner• Just in time (JIT)
Equipment deliveries
• Detailed simulation installation
• Visual Validation for payment approval
ESTIMATING• Real time
conceptual modeling and cost planning (Dprofier)
• Quantity extraction to support detailed cost estimates
• Trade Verification from Fabrication Models
• Structural Steel• Radar• Mechanical
Plumbing• Electrical• Value Engineering • What if scenarios• Visualization• Quantity
Extractions• Prefabrication
Solutions• Equipment rooms• MEP System• Multi-Trade
Prefabrication• Unique
architectural and structural elements
SUSTAINABILITY• Conceptual energy
analysis via Dprofiler
• Detailed energy analysis via EcoTech
• Sustainable element tracking
• LEED tracking
FACILITY MANAGEMENT APPLICATION• Life Cycle BIM
Strategies• BIM As-builds• BIM embedded 0&M
manuals• Cobie data
populations and extractions
• BIM Maintenance Plans and technical Support
• BIM files hosting on Lend Lease’s Digital Exchange System.

Improved visualization
Improved productivity via easy information retrieval.
Increased coordination of construction documents
Linked vital information such as vendors for specific materials, location of details and quantities required for estimation and tendering.
Increased speed of delivery.
Reduced overall costs
