Definition “What is IFC all about ?”

Short History of IFC “Where are we today ?”

Workflows today with IFC “Every exchange has a purpose”

The future of IFC “Where will the journey take us ?”

Definition ›› History ›› Today ›› Tomorrow

A structure to store and exchange BIM data or the standard for “open BIM” • well defined and documented data schema

• determines BIM data exchange Properties Lin k to w all Geo m etry

Door The important IFC values are: • open Wall • neutral • comprehensive Duct • customizable • extensible

IFC Overview Presentation © 2014 AEC3 Deutschland GmbH IFC –a buildingSMART and ISO standard buildingSMART an organization being • Independent • International data • Not for profit • Open to all in construction

buildingSMART standards • Consensus based industry standards ISO16739 (IFC) • Requirements are project driven • Standards are open and maintained • Collaboration with ISO for formal standards

Use IFC as intended • share and distribute !

IFC 1.0 to IFC 2.0 –early prototypes use: 2000 -2002 IFC 2x to IFC 2x2 –early adopters use: 2002 -2008 IFC 2x3 –in practical use today use: 2008 -2017 IFC 4 –released, forthcoming use: from 2015 onwards

• About 2-3 person/years per year direct development effort

• Time spend in buildingSMART International MSG (»50% volunteered)

• More spend by external reviewers, project development teams, bSI community

Specification work is the tip of the iceberg

• Software development efforts (about 150 applications supporting IFC)

• Open BIM guidelines, training, education, etc.

Single goal: secure IFC as the true openBIM standard worldwide

First ever IFC exchange –1996 at the ACS convention in Frankfurt Here examples from year 1999 (IFC1.5.1)

2.8GB IFC file with references. Combines AutoCAD (2D drafting), Tekla(3D structural), AutoCAD MEP (3D piping & mechanical), CadPipe(3D fire design), Revit (3D Architecture), and SketchUp. merged in Tekla. Source: Greg Robinson, Lucrosol quoted in upFront.eZine #681

There is no single “all-in-one” IFC implementation the “Full IFC” is a repository of schema definitions for all disciplines and life cycle the “IFC Model View Definition” is a subset, that satisfies one or many purposes

Any IFC implementation implements 1..n Model View Definitions
