1 Uses and Benefits of BIM

2 Project Life Cycle Owner - understand project needs Design team - analyse, design and develop the project Contractor - manage the construction of the project Facility manager - during operation and decommissioning phases

3 Key areas for BIM Design / Construction Intelligent 3D-Modelling Clash detection Visualisations Simulations Energy, Fire etc Whole Life Cycle Costs Quantity take-off, costing 4-D scheduling Supply chain management Safety Planning Facilities Management

4 3D coordination between subcontractors and vendors during early stages of design Information on materials and components available from model to meet O&M/FM & Investor s needs DESIGN Accurate and visual design Project Common Design Elements and Product Components in use, libraries and catalogues As Constructed remeasured and verified with adequate detail

5 Clash Detection Better production planning with sub contractors, visual plans Zero clash through collaboration and sharing Zero error design: No defects in construction phases, below ground and above ground assets/services Project checking rules: better design quality

6 Visualisation Visualizations of buildings for Walkthroughs with client/stakeholders Virtual reality mock ups and animations, fly over/through, buildings inside and outside Supports customer interface, choices etc (assortments, catalogues, selection tools - shopping lists)

7 Simulations - Energy, Fire etc More accurate and easier energy calculations Helps to achieve green construction goals, CO2 footprint, LEED, BREEAM, WRAP and Embodied Carbon Possible to simulate indoor climate conditions Supports smoke and fire simulations (buildings, tunnels etc)

8 Whole life costs Accurate life cycle cost estimation Link Capex and Opex to get Totex Life Cycle Assessment to evaluate environmental aspects where required

9 Extract quantities of work to prepare costs estimates to costs database or excel file - easier to connect quantities to costing, scheduling and procurement Update schedule and costs - Material quantities can be automatically extracted and changed Quantity takeoff, costing Easier to evaluate design changes and impact on costs (5D design) Rapid and accurate take off of materials quantities

10 4-D scheduling Information for scheduling from model based quantity take-off 4D design 4D simulations, optimised schedules Visualisation of schedules for workers and suppliers

11 Constructability Analysis

12 Health and Safety Safety details and structures in libraries (standardization) Safety installations pre-planned, railings and fixings for safety equipment Visual safety tours / area plans and presentations embed maintenance /access zones for plant and equipment -verification spaces are kept clear

13 Building the Asset Information Model 100% Space, system & equipment layout Graphics Graphics 0% Graphics Attributes Data Attributes Model progression Data Product data, as built layout, Tag & serial no., warranty & spares Attributes Design Construction Operation Project Information Model Asset Information Model

14 Facilities Management Computer aided facilities management to ensure effective maintenance of assets Ensures maintenance and asset performance history maintained Enables FM contractor to effectively manage and optimize maintenance services

17 Benefits Faster and more effective processes information is more easily shared, can be value-added and reused. Better design building proposals can be rigorously analysed, simulations can be performed quickly and performance benchmarked, enabling improved and innovative solutions. Controlled whole-life costs and environmental data environmental performance is more predictable, lifecycle costs are better understood. Better production quality documentation output is flexible and exploits automation. Automated assembly digital product data can be exploited in downstream processes and be used for manufacturing/assembling of structural systems. Better customer service proposals are better understood through accurate visualization. Lifecycle data requirements, design, construction and operational information can be used in facilities management

18 Benefits Client Survey More accurate integration of all elements design yes time and costs efficiencies and the ability to demonstrate our team can deliver larger projects and thus generate greater fee income yes co-ordination issues resolved early, cost saving, maintenance programmes for end user, building information easy to acquire if building to be remodelled/extended we are currently able to offer a more detailed and comprehensive service for more or less than half the fee that we were able to 6 years ago Yes, reduces costs of both construction and FM

19 Top Benefits Reported Lower construction costs Fewer errors Less rework Increases co-ordination of documents Improves productivity due to easy retrieval of information Lower operating costs
