What is a Building Information Model?

2D Draftingindividual 2D plans – paper spaceno risk control by clash detectionno calculation of quantities, costs, thermal loads, etc.

3D Modelvisualisation – model spaceclash detection on 3D geometryno calculation of quantities, costs, thermal loads, etc.

building model (now called “BIM”)intelligent elementsderivation of 2D plansclash and risk assessmentcalculation of quantities, costs, thermal loads, etc.

What are IFC implementation today?

Why do we need to chance?

client satisfactionbetter building performanceless time, less costsbetter predictability

cost efficiency in design officereduction of labor cost increased added value by integrationcompetence instead of lowest cost

risk management timeliness of changesverify it virtually, not on siteone change, all documents updated

What needs to change?

peopleovercome resistance to changeset-up high performance teamsset realistic goals

processcurrently sub-optimized processesnew methodologies with little experience – management commitmentcreate confidence by stepwise change

toolsnew software generation (2nd CAD)new environments, like DMSnew interfaces, like IFC

What are the potentials?

better value for clientscoordination and marketingtime and cost savingslife cycle costs

added value for consultantscompetence for acquisitionnew services for client (FM, LCM)reduction of labor costsreduction of risk (less errors)process optimization in-house

added value for project teamstool support for partneringprocess optimization project-wide

Do it stepwise!

Coordination with client using IFC

Client satisfaction

3D BIM workhigher data qualityvisualization on demandless errors by model verificationless time for coordinationconfiguration managementone model for (almost) all

neutral IFC deliverychoice of best designer in-house standardization (Bentley) and freedom for external data better coordination across many disciplines

Large scale transportation project

ongoing projectearly design completeddesign phase has started

first project using BIM throughout the project

from early design to hand-over of production model

establishment of new design processes

hole/recess coordination architecture & mechanicalschedule and room-book generation from BIM

Training: architecture to mechanical

process currently establishedtested by IT/BIM departmentused for trainingdeployed to the Berlin project

architect creates 3D/ BIM model (Revit) mechanical engineer references arch modelcreates mechanical design (RoCAD + IFC)

and creates proposals for recesses

Training: mechanical to architecture

architect imports recess proposal (Revit + IFC)i.e. no(t yet) openings

architect references mechanical model(Revit + IFC)

Generisches Modell: Wanddurchbruch WD

and creates real opening or recessesby accepting, or modifying proposals

Training: architectural to mechanical

architect exports updatedarch. model (Revit + IFC)

mechanical engineer references arch. model(RoCAD + IFC)

and makes automatic clash detection

From idea to reality

1.) Revit IFC Import in ADT

2.) Air Con in RoCAD

3.) Sanitary in RoCAD

4.) Check and clash detection

Adding automatic clash detection

at the end it should be easy and make fun !!!
