3 What is BIM? Building Information Modeling Answers to these questions differ according to your role within the AEC sector, and perhaps even depend on specific profile within each profession Is it a 3D model with all the necessary embedded information? Is it a methodology that enhances collaboration throughout the designing cycle (and potentially beyond) and among disciplines? Is it a procedure that reduces tendering and construction risks by making the access to the design data more transparent and complete? BIM: drivers of change The process of generating and managing data and information about a building during its entire lifecycle (R.Howard, B.-C. Bjork, 2008) 5 BIM technology One of the most promising developments in architecture, engineering and construction (AEC) sector. (BIM Handbook, 2011) A method for industrialization of knowledge (A.Ciribini, 2014) Process Culture 2
6 BIM as Technology: basic concept DRAWING Representation of reality (graphic) INFORMATION MODELING Informed representation of reality (graphic + information + parameters+relations+ behaviour+interoperability ) 7 BIM as Technology: : from 2D to 7D Geometry + information Scheduling (time) Estimating (quantities, costs) Sustainability Life-cycle management (concept design detail) AR (Augmented reality) 3
8 BIM as Process: stakeholders in the AEC sector Clients/Owner/Public Administration Leadership, Strategic Planning, Organizational Management, Tender, Bidding and Procurement, Contract Admin, O & M Architects, Engineers Concept, Design, Drawings, Analysis, Estimation, Bill of quantities, clashes, design management Contractors/Sub-contractors/Fabricators Production, cost/quantity estimation, prefabrication, construction, site management, 4D, 5D http://www.tekla.com/company/building-construction/open-bim http://www.bimthinkspace.com/ 10 BIM as Process: new approach (benefits) in the AEC sector Transparency vs opacity (model checking, clash detection) Effectiveness vs inefficiency (saving of time, money, energy) New models of design/tender: Integrated project delivery (IPD) BIM: BIM aware stakeholders (client, designer, contractor, etc.) 4
11 BIM as Process: a change of paradigm «Design with the end in mind» Efforts/costs/effects/risks in the EDP! - Cooperation among stakeolders (client, architects, engineers, contractors, etc.) - Multi-disciplinarity - Integrated project/process 13 BIM as Culture of integration (collaboration, sharing ) DISCIPLINES: architecture, construction, engineering TIME: Building Life-cycle SECTORS: owners, architects, clients, contractors, users SCALES: material, component, building, urban environment PHASES: Concept, EDP, Design, Construction, O & M, B I M Behavioural Integrated Model Collaborative team Design management Design integrator Shared risks and rewards 5
14 BIM as Culture: Integrated/Complex systems Human organism (bones, muscles, veins, organs) Building organism (structure,envelope,services ) Integration Source: 3d Anatomy-Pro, Autodesk Revit 15 I = Integration = Innovation BIPV Components, Products, Technology Function, Requirements Costs Architecture Building envelope 6
16 BIPV and function: from service device to building element PV as an energy device Function=energy production PV as a building skin Function=building component + energy production (Multifunctionality) Building requirements/function, standards, constructive concept Source: Si-Indach, UFE 17 BIPV and building envelope: from accessory to system PV as an overlapped component Role=accessory (energetic) PV as a building element Role=basic element PV as a building element Role=element of layering PV as a building element Role=unitary system Source: UFE, Neosolpan, Solrif, Naps System 7
