Certication success for software vendors

New stringent process provides quality assuranceThe rst four products to receive the new-style

buildingSMART certication 2.0 were recognised at

the bS international meetings in Waltham, near

Boston, US, in March 2013. The certication

marks the successful completion of a series of

demanding test cases and gives the software

vendors the right to display the

buildingSMART certication

logo on the product packs.

Our certication is a stringentprocess, says Rasso Steinmann, wholeads buildingSMARTs ImplementerSupport Group and is responsible forthe certication process. The numberof test actions to date is over 1,400 an indication of how seriously wetake the process. The certicationacknowledges that the products havebeen tested and shown to complywith the IFC open standards for thefunctions specied within the testingenvironment.

The four successful productswere Autodesk Revit Architecture,Graphisoft ArchiCAD, NemetschekAllplan and Nemetschek SciaEngineer. In April, Autodesk RevitStructure became the fth product toachieve certication.

Certication and open BIM

Good interfaces are essential ifopen BIM is to be made a reality.Certication has a vital role to play

in ensuring that the interfaces of IFCsoftware function without any hitchesor impairment of data quality and thatend-users can be sure the product istruly interoperable.

We found that the certicationprocess improved the qualitysignicantly during the course of the

testing, says Rasso.Building ownersare beginningto demand theuse of certiedsoftware in their

projects and

awards underlined the interoperability

that the certication guarantees,notably between the architectural andstructural disciplines, as well as MEP,and the chance to strengthen openBIM collaboration.

Next steps

As certication tests the nal releaseof the software product, end-usersdo not have long to wait, and thesoftware vendor may choose to shipa new version or service release of

the product shortly after certication.Twenty more applications are in thecertication pipeline.

The level of demand produceda bottleneck at one point, but theauditing team is now well resourced.Importantly, the present audit team,based in Germany, is being expanded,and Rasso is working with colleaguesin France to set up a further auditteam there.

Certication 2.0 is open to all software

developers who are buildingSMART

members. For more information, contact

BuildingSMART certication

What are the benefts to vendors?

Enhances QA of the softwareproduct

Allows automated testing through

GTDS platform (see text)

Offers a unique opportunity for

software vendors to check their

applications Provides a valuable marketing tool

Shows proof of commitment to open

BIM

Meets contractual demand for

bS-certied applications

certication isbecoming an importantcomponent of the roll-outof open BIM.

How it works

Certication 2.0, launched in 2010,replaces the earlier buildingSMARTcertication scheme which followeda different concept. The presentscheme introduces a clear distinctionbetween import and export functionsand improves quality checks. It usesa web application, the Global Testingand Documentation Server (GTDS),which provides automated onlinetesting of IFC les and tools for thedocumentation of manual tests,and is a place where candidates forcertication can run tests to ascertaincompliance. The database of GTDSstores all test results and providestest reports.

No vendor-independent testingframework for a standard data formathas attempted such an ambitiousscope until now, says Rasso. Theauditing process was especiallydemanding and this rst round of

certication for exports has earned therespect of the industry.

Industry response

And the response to the certicationresults has been positive, with thecertication process expected tolead to mature IFC interfaces inBIM applications something thatbuilding owners are also welcoming.As Autodesks Jim Lynch pointsout, many customers worldwide

mandate a neutral IFC le format...buildingSMARTs IFC certication willfacilitate more efcient, collaborativeworkows and increase project teamcollaboration.

Progress at Waltham

The twice-yearly meetings ofbuildingSMART and its workinggroups took place in Waltham, nearBoston, US during 1115 March 2013.

A drive to extend IFC toinfrastructure has become animportant elementof buildingSMARTs

portfolio of work, and asignicant developmentat Waltham wasthe formation of theopenINFRA Room acentre of activity, led byChristophe Castaingof Egis and the French-speakingchapter, dedicated to infrastructurework. We are setting up four projectsto develop use cases and explorehow to apply IFC to infrastructure,

says Christophe. The OpenGeospatial Consortium a US-basedorganisation that develops standards is committed to collaborating onlinking up IFC and GIS and joined

Priority technical projects

buildingSMART for the sessions oninfrastructure.

Product Room, Data

Dictionary and Process Room

The Product Room thecentre of activity that is developingbuildingSMART products

concentrated on the much-needed buildingSMARTData Dictionary (bSDD),making possible productlibraries that will linkproducts seamlesslyinto processes such asdesign and specication.The Product Room has

secured a grant from the Norwegiangovernment towards paying partof the cost of taking the workforward and developing a contentmanagement tool. The rst step is to

prepare a requirement specication.The accreditation of IFC4 as a

full ISO was a source of satisfactionto the Process Room and the

International User Group (IUG),who considered ways of promotingIFC4 and incorporating it into thebuildingSMART certication process.Meanwhile, the rst four certicationsunder the Certication 2.0 schemewere announced (see page 1).

Other highlights

Also discussed at Waltham were the

plans to develop international BIMguidelines, drawing on a number ofsources, notably ISO 12911:2012,Framework for BIM Guidance.Training is also on the agenda for anumber of chapters, with determinedtraining efforts evident in the UK,Korea, Norway and the Middle East.There were meetings of IUG, theInternational Technical ManagementGroup (ITM) and the ImplementationSupport Group (ISG).

The Technical Advisory Group of bSI

has identied six priority tasks which

will improve data exchange and

data understanding and will hasten

integrated working. The immediate

trigger is the UK governments initiativeto require the use of BIM in public

sector projects at Level 2 of the

maturity model by 2016 and gearing

up for Level 3. Some of the tasks

have two parts, and the six tasks andsubtasks are dened as follows:

Create logically linked

heterogeneous models

(integrated models) for

Level 3 establishing structured

data exchange and sharing to

support complex engineered assets

of different types throughout their

total life-cycle

Dene the function of IFC

objects and attributes relative to

building denition and operation

expanding the use of BIM to

cover operation and maintenance

Develop an archival model

view dening a Model View

Denition (MVD) that will record the

project as built, with full product

information and prescriptionsas to what historic data must be

preserved

Support web-based tools toallow exchange requirements

exposure and automated testing

by end users enabling simple

automated testing of a building

model against the Model View

New Roadmap to 2016 in draft

A new business plan to 2016, accelerating

buildingSMART technical and useractivities, is being developed. Our existing

business plan was simply too conservative

over timings and coverage, explains Chris

Groome, bSI business manager. The old

business plan, Roadmap 2020, envisaged

a steady but slower development and roll-out of the buildingSMART technical output.

With the UK government BIM programme,

bSI as a whole must tackle the unmet

needs of those who are implementing

BIM, he adds. Other countries will benet

as well.

The second factor behind the new

business plan is the project to create IFCfor infrastructure. This has become a core

buildingSMART activity and needs to be

reected in the business plan.

With much sharper timings and the

inclusion of openINFRA, the new businessplan will act both as a planning tool

and the basis for seeking funding from

potential beneciaries. Other priorities

have also been identied by the ProductRoom, the Process Room and the

International User Group. Seven use

cases have been selected as areas of

work where seamless data ow will help

improve efciency and sustainability.There is also a clear need for international

BIM guidelines to overcome the present

local fragmentation. As before, training is

deemed vital, possibly accompanied by

bSI end-user certication in open BIM.

Business Plan to 2016, contact Chris

standard, to ensure that it

really can support interoperable

data exchange

Create a collaborative denition

of exchange requirements at

both IDM (Information Delivery

Manual) and MVD level using

a modular approach known as

the Semantic Exchange Module(SEM) to allow the design and

construction teams to dene

implement them

Develop a methodology and

software to track BIM data

origin developing an open-

source software app that will showthe source and time of all data

entered into a BIM, so that thosewho enter bad data have to take

responsibility

Enable ownership of mixed data

Rennes metro turns to IFC

Rennes is the smallest city in the world to have a full metro

and one of six cities in France to have a metro system.

The Rennes metro opened in 2002, with a single 9.4km line known as Line A running north-west to south-east. Now a secondline is planned, based on a strong social and business case: it willprovide sustainable development, prevent gridlock at surface level,meet the needs of the future and allow expenses and operating

revenues to balance out. The capital funding is provided by centraland local government.The new Line B, running north-east to south-west, is 14km long and

will consist of a mined tunnel, together with a stretch of cut and covertunnel and a viaduct. There will be 15 stations and, as with Line A,some stations will offer park and ride.

French buildingSMART member Egis is responsible for the designand supervision of the stations and tunnels. For the 15 metro stations,we have persuaded the client [Rennes Metropole] to require bidders toprovide digital models in IFC 2x3, says Christophe Castaing, of Egisand buildingSMART. The IFC model must cover the domains specied(including civil works, doors and electrical and mechanical).

This represents a pioneering example of IFC in public sectorprocurement in France and follows the recommendations made bythe French-speaking chapter to the Ministry of Ecology, SustainableDevelopment and Energy on how procurement regulations might bemodied to include an IFC requirement.

This use of IFC in a public sector infrastructure project covers thestations, not the metro line itself. As Christophe states, For the linearpart of the project, there is no software at present able to deliver anyIFC information showing how much openINFRA is needed.

Botn arts centre in Spain using BIM

The rise of container shipping has led

to the decline of the old docklands inSantander on Spains Atlantic coast.But now the area between the seafront and the historic quarter of thetown is being redeveloped, linkingthe 19th-century Pereda Gardens toAlbareda Quay, facing the bay. Anexisting arterial road is being takenunderground and a large unsightlycarpark replaced by a public space.

The jewel of this redevelopment isa new arts centre, sponsored by theBotn Foundation, a leading privatefoundation for social investment. Theconstruction is complex, with twolinked buildings, clad in ceramic tiles,which will reect the changing light ofthe water. Thats the quality we wantto celebrate, says Renzo Piano, whodesigned the centre.

OHL, the main contractor, decided

to use virtual construction techniquesto help the construction process andhired B.O.D. an active member ofthe Spanish chapter (in formation) as BIM consultant to create amodel prior to construction and toco-ordinate progress. As a result, theBIM is being used for clash detectionand constructability, and importantly helping the construction team tounderstand this complex project.During the design process Teklaand Revit software was used, withinteroperability achieved through IFC.

The use of BIM is exemplied inthe pachinko the stainless steelstructure between the two buildings,named by Renzo Piano after theJapanese pinball machine whichwent through a number of designiterations. This made it necessary torevise the quantity take-offs severaltimes a process much simplied bythe use of BIM,which allowed a

high degree ofaccuracy thatis not possiblewith the oldertechnologies,

and also improved

productivity.A prestige project

like the Botn Centreis a source of prideto Spain in thesetough economictimes, says SergioMuoz, directorof innovation atAIDICO and bSSpains president.For information about

Launch of buildingSMART Hong Kong

A new chapter of buildingSMARTwas launched in Hong Kong on 25

April 2013. Around 150 delegatesrepresenting leading owners,construction companies, developers,facility managers, governmentdepartments and professionalinstitutions attended the launch.

We are proud to be part ofbuildingSMART International family topromote industry awareness on BIMand open international standards,the technology that will benet ourconstruction industry, state and nation and further the cause of international

understanding, said Nelson Ho, founding chairman of the new chapter.The Hong Kong Chapter has all the signs of becoming a heavyweight player,says Chris Groome, bSI business manager, who took part in the inauguralceremony.

and a new China chapter tooAn earlier buildingSMART chapter in China, created in 2008, discontinued itsactivities some time ago, leaving a country that has a massive constructionindustry and a growing interest in BIM without any formal link withbuildingSMART. This has been remedied with the launch of a new Chinachapter, now with stronger foundations.

An annual summit/industry day is planned, complemented by a BIM technicalforum and a BIM business salon held in different cities around China, to shareknowledge, provide networking and stimulate business opportunities. Therewill be events to share best practice within China, and the chapter plans activeengagement with buildingSMART internationally.

The China chapter is condent that through its effort the worlds largestbuilding market, China, will be led into a brand-new BIM era based oninternational standards, said Yinquan Yu, founding chairman of the chapter.

The future with IFC4

Interview with Christopher Zoog, HOK

Christopher Zoog is an HOK buildingSMART specialist an architect who

works on key projects around the rm ensuring compliance with its HOK

buildingSMART initiatives. His work featured briey in the IFC4 Special

supplement. Here he answers questions from newsletter editor Betzy Dinesen.

BD: When and how did you become

aware of IFC4?

CZ: Ive been following the

development of IFC4 for quite a whilenow. I became interested in IFC aboutthree years ago when I arrived atHOK, which has a strong presence inthe buildingSMART community.

What is your role with HOK?

It can be thought of as an appliedresearch role: I research newtechnologies and workows and applythem to the projects I am working on.I am also an expert in model-basedco-ordination, model checking, designalgorithms and pedestrian simulation.

Can you tell me something about

the project where you did the early

IFC4 connection between Rhino/

Grasshopper and Revit?

This example of IFC4 integration is acomplex faade study for a major newhospital building in New York City.

What benet did making the

connection bring to you?

In the early design phase our primaryBIM tool was not exible enough tohandle the complex geometry and the

many design iterations in a uid way.Normally we would devise a designalgorithm to create the geometry inGrasshopper/Rhino and perhapscreate a .dwg or .sat le that can beimported into Revit and referenced adumb piece of geometry.

IFC4 and the Geometry Gymplugins allow us to create an IFCmodel in Grasshopper and thenimport/merge that model into Revit,where they become proper BIMelements, panels, columns, oors,etc. We can also pass that sameinformation on to structural analysisprograms, such as Tekla.

How do you see the potential of

IFC4?

I anticipate that the adoption of IFC4and development of new model viewdenitions will further revolutionise

how building stakeholders collaborateand communicate with each other.Its an exciting time for the AECcommunity.
