CIC’s Roles and Support 1. What is BIM ? BIM • Building Information Modelling • Building Information Management • Virtual Design & Construction (VDC) • 建築信息模擬 (Hong Kong) • 建築信息模型 (China) • 建築資訊模擬 (Taiwan) Limitations of 2D Drawings • Difficult to visualize the design with separate drawings • Plans • Elevations • Sections • 3D views • Perspectives • Details • Schedules The elephant metaphor of reality • 2D drawings limit information accuracy & coordination • Drawings cannot be used as ‘input’ for scientific and quantitative analysis, i.e. –performance validation Information and Model 2D ‐ Drawing 1D – Text Information 3D ‐ Model • Area Schedule • Plan • Finishing Schedule • Section • Door/Window Schedule • Elevation • Beam/Column Schedule • Area Diagrams • Equipment Schedule • Schematic Designs • Program • General Building Plans • Cost Estimate • Structural Plans • Quantity Take Off • E/M Drawings • Bills of Quantities • Schematics • Variations • Other Diagrams / Details CAD Vs BIM (3D Model) Object based Parametric geometry + Attributes http://www.cadtobim.com/what‐is‐bim.html Parametric Change Engine in BIM Automatically coordinates changes made anywhere –model views, drawing sheets, schedules, sections ad plans e.g. Change or delete the roof light in any views will automatically coordinate others, hence no discrepancies among drawings, schedules. Building Information Modelling • BIM is the process of developing and using three‐dimensional, digital representation of building data throughout its life cycle. • BIM ‐ the creation and use of coordinated, consistent, computable information, 3D presentation about a building project in design, construction & maintenance Architectural Structural Building Services Applications of BIM BIM Models Coordination Collaboration Logistics Prefabrication Documentation ‐ 2D Drawings Project management Visualization: Rendering Simulation Performance Analysis The information in the model can be updated, shared and used by design & construction teams throughout the entire project development cycle. (A, SE, BSE, CE, GE, QS, LA, FM, contractors, suppliers, Code / Collision Check client, PM, etc.) Material Quantities / Costing Use of BIM throughout Project Development Cycle Project Life Cycle Scheme Detailed Construction of Completion, Feasibility / Tender Design and Design and Foundation / Management & Planning Documentation Project Budget Specification Building Maintenance BIM Enables Sustainable Design Conceptual Design Design Development Design Validation Conduct whole building Use early-stage energy, water & carbon Make detailed design massing models analysis • Optimal location • Benchmark energy use • Adjust rooms and zones • Building form • Recommend potential • Size and shape individual • Orientation of building savings openings design • Study alternatives • Design custom shading devices • Choose optimal materials Structural Engineering –Design Drawing Production BIM Structural Model Framing Plan Collaboration Clash Detection Analytical / Design Model – ETABS / ORION Source: Hong Kong Housing Authority Building Services Installation Air Condition Installation FS Installation Electrical Installation Source: Hong Kong Housing Authority Geotechnical Investigation Integration of Geotechnical data into construction process Source: Hong Kong Housing Authority Building Models for Virtual Design & Construction Performance validation & check buildability https://www.healthandsafetyatwork.com/construction/bim‐spells‐safety‐site Source: http://www.metconus.com/services/bim/ https://www.vrroom.buzz/vr‐news/business/6‐companies‐changing‐construction‐vr Source: https://www.bdcnetwork.com/altered‐reality‐showdown, courtesy Trimble BIM Enabling Safety In Construction Site Process Design for safety •Construction and operation planning • Relationship between working time & space • Validation of construction sequence • Anticipate the interaction between workers & machineries •Evaluation of safety from workers viewpoint •Concern from the public Source: Hong Kong Housing Authority Clash Detection & Maintenance Access Building Services, False ceiling, Structural Elements Clash detected with report generated for rectification Ensure space for Maintenance Access Calculation with BIM The BIM concept supports a wide range of calculation and estimating activities: • Quantity take‐offs • Door/window schedules • Room/Furniture Inventories • Cost estimations • Cash flow analysis Facility Management • As‐built BIM model • Linking Information to BIM model e.g. detailed shop drawings linked to balustrade in 3D view Balustrade selected Basic Information e.g. height, type of glass Detailed Drawings Dimensions of BIM • 3D ‐ 3D Model • 4D ‐ Scheduling & Simulation • 5D ‐ Quantity & Cost Estimation • 6D ‐ Sustainability & Performance • 7D ‐ Facility / Asset Management Source: bimporn.tumblr.com 2. What are the benefits of using BIM? Benefits of using BIM Design • Enhance the effectiveness of design co‐ordination. Changes are automatically coordinated across the project and information generated is therefore of high quality • Improve communication among project team • Facilitate design analysis studies Construction • Enhance building constructability and reduce errors on site due to uncoordinated information in 2D drawings • Reduce rework and hence construction waste • Facilitate site planning including site safety measures Post‐completion • Quick and easy extract of building information for facility / asset management and maintenance BIM Source: http://www.autodesk.com/temp/pdf/McGraw_Hill_Business_Value_of_BIM_ANZ.pdf BIM Adoption – Private Project HIGH RISE BUILDING PROJECT Name of Building: One Island East Client: Swire Properties Main Contractor: Gammon Construction Completion: 2008 Description: 1.5 million sq. ft. 70-storey Hong Kong office building.
