Quality CAN NO LONGER BE OPTIONAL We live in interesting and challenging times. The economic situation in many countries is strained. This is a time that requires change and demands innovation as we strive to meet our personal and organizational goals. Currently, the building industry is spending tens of billion dollars more than necessary each year because of poor quality, and outdated, or even non-existent quality practi-ces. At the same time, we are strongly encouraged to focus on delivering environmentally friendly and sustainable projects that are also much more challenging, from the design and construction perspective.Should we save on design costs? Many studies show that waste associated with design and de-sign-related problems is actually more than the cost of design itself. So, what should we do? Let me phrase it this way: Just reading this magazine suggests that you are on the right track.In this issue of the Solibri Magazine, we have assembled some interesting ar ticles about success-ful projects where Quality Assurance and Quality Control (QA/QC) have made a significant and tangible difference. You will also find interesting customer cases profiling BIM projects where the Solibri Model Checker application has been used for QA/QC. As is the case with all good technolo-gy, our users find creative ways to use this technology, essentially stretching it to new limits. From our perspective, this is fantastic!One key ingredient to deliver consistently high quality is to set clear BIM guidelines and require-ments. Reliable information is required in order to generate accurate cost estimates and energy calculations. This is only possible when the information requirements are clearly stated and pro-per modeling practices are followed. We have excellent examples from the U.S. General Services Administration (GSA) BIM Requirements, Statsbygg’s BIM Guide in Norway, and the National BIM requirements for Finland to mention just a few.A great way to use QA/QC is to require it during design competitions. This allows you to ensure comparable alternatives which make it possible to better analyze the characteristics and behavior of the design. Solibri is also thinking and executing strategically. We are actively participating in several projects that relate to QA/QC solutions and processes, In the US, the FIATECH sponsored AutoCodes (Ex-pedited Permitting) project is an example of our commitment to delivering consistent quality to the global building code checking and review process. Finally, in this issue we are introducing the newest version of Solibri Model Checker, v7. As our users have come to expect and appreciate, this version introduces new features and innovative capabilities to fur ther refine the QA/QC process. We encourage customer feedback and we make every effor t to actively listen to all of our customers. We also continue to engineer our offering to deliver greater speed and higher performance. In other words, we hold ourselves to a strict QA/QC process, internally.Our commitment is to continue to lead in the world of model-based QA/QC by providing solid technology tools that make it possible to achieve consistently excellent performance. This means we will deliver value and you will be able to use our technology to create your own QA/QC process to maximize your benefit. The information is in the model. The quality of that information depends upon the author, but the ability to measure the quality and verify accuracy is in your hands, as a Solibri customer.

A Century of Building ExcellenceLemminkäinenisa100-year-oldFinnishconstructiongroupwhichoperatesinal lsegmentsoftheconstructionsector.LemminkäinenisthenameofaGod-l ikeherointheKalevala–Finland’sNationalEpic.

”A number of individuals working in the construction industry had the idea of establishing their own asphalt and cement business in

Helsinki in the form of a joint-stock com-pany”. Those words opened the first an-nual report of Asfalt ti Oy Lemminkäinen for the year 1910.

Finland was in its f inal years as an Autonomous Grand Duchy of the Rus-sian Empire, and aspirations of nation-hood were much in evidence. Patriotic fervor also infused the business world. Master builders had been trained in Helsinki since 1883, and now they were enthusiastically building the capital city at the beginning of the 20th century.

LemminkäinenTodayToday Lemminkäinen i s a leading construction company. Lemminkäinen operates in building construction, inf-rastructure construction and technical building services, simultaneously exp-loiting new technologies and processes such as BIM, and developing capabili-

t ies with new business models inclu-ding Public-Private Par tnership (PPP).

Lemminkäinen Group operates in Finland, Russia and the Baltic region, as well in all areas of the construction sector. The Group's business sectors are building construct ion and infra-structure construction and technical building services. Net sales in 2010 were approximately EUR 2 bill ion, of which in ternat ional operat ions ac -counted for roughly a quar ter. The Group employs about 8 300people.

BIMIstheBestWaytoBuildLemminkäinen is known for i t s ex-per tise in building and infrastructure construction. The company is enhan-cing personnel competency, and the-reby ef f iciency. To retain the leading market posit ion in these f ields, Lem-minkäinen has adapted the mindset of continuously developing and improving business operations. One of their st-rengths is BIM.

5CASE STUDY

BIM has been developed for use in steering the design and planning pro-cess, project management and produc-tion control. This development work ge-nerates added value for customers by providing them with illustrative informa-tion models that help them make deci-sions. BIM also raises productivity and improves information flow between the various par ties working on a project.

By the end of 2011, Lemminkäinen intends to use BIM on all constructi -on projects with subcontracted design services. In Lemminkäinen’s view, BIM boosts planning efficiency. All produc-tion material data can be saved in the same database, all par t ies have ac-cess to the same up-to -date project data and it’s easier to integrate various subsections. BIM also increases cost-effectiveness.

“BIM is the best way to build. What is required is rather a cultural change than a change merely in practices. With interoperability, cooperation and active attitude BIM projects will be extremely ef f icient.” says Mrs. Karppinen. “The benefits are clear. High quality models enable us to use model information in various business functions such as cost estimation and scheduling without the risks that exist in exploit ing ordinary plans. Also, the building phase is less error prone and the construction phase smoother.”

PublicPrivatePartnershipPublic–Private Par tnership, sometimes referred to as PPP, P3 or P3, is a busi-ness venture that is funded and ope-rated through a par tnership of one or more private sector companies and a public body. PPP has been used for providing various types of services and is not limited to construction in many countries.

The purpose of Public-Private Par t-nership is to create a public -private venture enabling the production of ser-vices, such as building infrastructure or providing health care, without the tradi-tionally heavy public initial investment and cash outlays that have historically burdened the public sector. The main rationale is that while the need for ser-vices increases, the effective par tner-ships enables utilizing the lower capi-tal cost of the public par tner and the know-how, resources, capabilities and ef fect iveness of the private par t ies, creating both synergy and a win-win si-tuation.

PPP comes in many f lavors depen-ding on the scope of the services ren-dered by the private par tner such as Design-Build-Finance-Maintain (DBFM) or Design-Build-Finance-Maintain-Ope-rate (DBFMO). In the former, the private sector designs, builds and finances an asset and provides facility management or maintenance services, and in the lat-

ter the private sector also operates the building under a long-term agreement.

A typical transpor tation infrastruc-ture example is the E18 motorway pro-ject, which included the construction of 51.3 km of new motorway as a four lane dual -carr iageway, seven motor-way tunnels with a total length of 5.2 km, eight interchanges and 48 bridge sites. Lemminkäinen and another major construction company took par t in the joint venture responsible for two cont-racts: first for design and construction, and the second for maintenance, until 2029.

Thus, from the point of view of the private par ties providing the service in the par tnership, a substantial f inan-

cial, technical and operational risk is included in the projects. Risk manage-ment and mitigating risks requires high quality design and construction. This is where BIM comes in.

PPPinRealEstate:acaseOn 27 July 2009 Kuopio Ci t y Board selected Lemminkäinen Corporat ion as the service provider for a major life cycle project. The project scope en-compasses the new construction and basic repair of four schools and one child day-care center. Lemminkäinen will be responsible for the maintenan-ce and upkeep of the buildings for a period of 25 years. The total value of the project is EUR 93.5 million. All the construction works of the project will be completed by autumn 2013. Mar tti Ahtisaari school and Puijonsarvi school have been completed. Rajala school and Puijonlaakso child day-care center will be completed in autumn 2012, and Pohjantie school by autumn 2013.

Mr. Matti Varstala, the project ma-nager in charge of the school project

Thereisnowayback.BIMwillbethewaywework.

states that PPP projec ts require a broad skill set. Being a large construc-t ion company that operates in many construction sectors, PPP projects f it Lemminkäinen ex tremely well. Having versatile skills enables Lemminkäinen to also take par t in making technolo-gy decisions that are impor tant in life cycle projects. A deep understanding of the capabilities of technology and the requirements of the use enables Lem-minkäinen to avoid a common pitfall of sub-optimizing design solutions.

The greatest benef i t provided by BIM has been the possibility to model and visualize the design solutions to all par ticipants in the project, from desig-ners to the end users and subcontrac-tors, and ensure smooth construction flow. The greatest challenge has been the correct timing of the design delive-rables in relation to the construction schedule.

BIM and qual i t y assurance have been used throughout the project. Nor-mally, tens of people take par t in the quality assurance during the construc-

t ion phase. Using BIM as the design method makes it possible to coordinate the design before construction begins. “Solibri Model Checker has proved to be a valuable tool to designers for loca-ting design problems. Quality assurance has produced concrete benefits, and we are satisfied with the ease that Solibri Model Checker isolates design issues.” states Mr. Varstala.

TheLemminkäinenWay“There is no way back. Naturally, this will mean that our designer suppliers will need to provide us with the models we require, and invest in learning to model in a way that fulfills our needs and requi-rements. BIM will be the way we work.” concludes Karppinen.

F r o m t h e p o i n t o f v i e w o f Lemminkäinen’s design suppliers, BIM has consequence s . Bec ause Lem-minkäinen intends to use BIM on all construct ion projects wi th subcont-racted design services, there will also be a new way to design and model for Lemminkäinen.

7CASE STUDY

BIM, as a practice and a pro-cess has been steadily evol-ving and will continue to do so for many years to come. In

many circles, BIM is too of ten equated with a solution or a par ticular tool. As has been stated in many forums, and even in this magazine, the true sustai-nable value associated with BIM is the information or the data that is asso-ciated, or nested, within the model (s). If we take a close look at the stakehol-ders on any project, we usually f ind that the BIM discussion is related to the design team, the construction pro-ject team and eventually the owner (in the ideal situation) . The explanation for this is simple. These are the par ties that have found value and benefits by adopting a collaborative approach to project delivery…, which is identified as vir tual design and construction (VDC) or BIM.

There is no doubt that the benefits of BIM are real, tangible and becoming more predic table and measureable. But there is something missing.

As design and construction introdu-ces more quality assurance and quality control (QA/QC) through the use of 3D models and BIM, an entire community of building of f icials and agency plan reviewers remain totally entrenched in the 2D paper review process. In some of the more innovat ive jur isdic t ions they have begun to work with digi tal content (e.g. pdf f iles), or online sub-mit tals, but these are still primarily in 2D. This group of professionals has been lef t out of the BIM dialogue, for years. It just doesn’t make sense.

Solibri leads the way to Model-Based Expedited Permitting A PERSPECTIVE FROM THE U.S.

When you consider the typical work-f low, the designer may be quite profi-cient at building data-rich 3D models, but when it is time to submit the design for plan or code review, they must ‘flat-ten’ the model to 2D, print on paper (most of the time at least 10 sets) and then submit to the reviewing authority. The cost to manually process the review is dependent upon the urgency that the customer indicates. Sometimes the re-view might take in excess of 2 months. But, for a steeper fee, it might be pos-sible to expedite the review and deliver comments within a day or two. Those comments are then addressed by the design enti ty, again in 3D, f lat tened again to 2D and re -submit ted to the agency for approval. This process of model…flatten to 2D…re-model…re-flat-ten and eventually gain approval is ex-tremely inefficient and potentially very costly, both in dollars and the possible delays associated with gaining the final approval. So, there are really 2 prob-lems (or challenges if you prefer). First-ly, the 3D>2D>3D>2D>3D exchange is reflective of a disjointed and potential-ly dysfunctional process. Secondly, the real adoption of BIM requires the inclu-sion of the review community. Without their involvement we will not be able to accurately predict our project schedu-les, not just for construction, but also possibly for financing, cost control and especially for operational timelines.

Solibri is in a unique position. As the developer of a QA/QC technology so-lution that ‘requires’ a model in order to deliver value, we are acutely aware of the broad market we need to serve. We have a solut ion that can play an

instrumental role in addressing both of the challenges identified above. We can solve the initial issue by providing a platform that enables the reviewing authority to accept, and even encou-rage the submission of models, rather than just paper drawings. The second issue was a matter of inclusion. Once the reviewing entities begin to review models they will become critical mem-bers of the broader BIM community. Their role will be extremely influential, as they will be responsible for streamli-ning the design>permit>construct con-tinuum.

The one aspect that wasn’t discus-sed here was ‘what does the reviewer check the model for, and how do they actually accomplish this? ’. This is a signif icant under taking and needs to be addressed in a systematic and met-hodical fashion. Solibr i is current ly engaged in the initial phase of a Proof of Concept Project that will deliver the capability to begin the transformation from 2D to BIM for this entire industry segment. This project, sponsored by the FIATECH Organization is known as AUTOCodes (for Expedited Permit ting) and is being conducted in the US. The details of the project are included in the announcement below. This is an example of the Solibri commitment (as well as our committee co-members) to delivering innovation to the global buil-ding code and review process.

In this project Solibri is working to-gether with FIATECH, The International Code Council ( ICC), Avolve Sof tware, and Target Corporation.

Even with the best effor ts of code officials to expedite approvals and permitting,

regulatory compliance remains a tedious, time-consuming, and costly discipline.

While building officials, construction owners, architects, designers, and engin-

eers have long understood the critical importance of timely, accurate and uniform

code-review, relatively lit tle progress has been made with respect to improving

and modernizing an outdated regulatory process. Only modest focus has been

placed on the significant impact code review and permit approval has on business

and consistent economic growth.

Now all of that has changed. Current economic conditions have raised aware-

ness of deficiencies in the regulatory process to the highest levels of government.

Across the country there is an urgent call to apply new thinking and technology

to the challenges facing jurisdictions. Forward-looking building and planning de-

par tments are investigating methods for streamlining their processes, including

faster, more consistent code checking.

The growing use of three-dimensional, building information model (BIM) techno-

logy by the construction industry presents a significant opportunity to accelerate

code reviews and expedite permitting. Through the application of programmable

sof tware rules, BIM data can be queried and analyzed for the purpose of deter-

mining regulatory compliance. This method utilizes the power of computers to

perform the majority of the code review while maintaining, and even improving,

the fundamental safety and design integrity standards which are intrinsic to the

regulatory process.

In January 2011, the FIATECH Regulatory Streamlining Commit tee launched

a proof-of-concept (POC) project to develop automated code-checking rulesets.

With the suppor t of the International Code Council ( ICC), jurisdictions from dif-

ferent regions of the United States and independent sof tware developers, the

initial phase of the project (named “AUTOCodes”) will demonstrate the viability

of using sof tware rulesets to check the Accessibility and Egress provisions of the

ICC’s International Building Code. To achieve this, the Project team is conducting

a comparative analysis between traditional, manual plan reviews and the results

of a BIM-based checking process.

In April, code officials and plan-check engineers from the participating jurisdic-

tions were given a set of 2D plans derived from a Target Corporation store prototy-

pe BIM. The jurisdictions were instructed to perform a standard Accessibility and

Egress plan review per their own standard building codes and methods. Collecting

results from these jurisdictions provided the Committee with key insight into the

way plan reviews are conducted.

The Target store BIM was shared with a software development team for the pur-

pose of checking the model for Accessibility and Egress compliance. The results

were to be assessed and analyzed to determine the need for creating or modifying

machine-language rulesets. As the 2D plan reviews were completed, the results

were passed to the software team to serve as a baseline for the ruleset develop-

ment effor t. The Target store BIM and POC rulesets will soon be distributed to the

jurisdictions for a model-based review and report. The results will be analyzed and

published in a final POC repor t.

The initial 2D review exercise is now complete. A findings summary of the pro-

ject work to date will be shared at the ICC Annual Business Meeting in Phoenix,

Arizona (Oct 30 – Nov. 3).

Long term AUTOCodes Project objectives include the development of an exten-

sive, open-source ruleset library which is approved and adopted by industry and

regulatory bodies alike. The rulesets are to be used by technology developers

in commercial companies and code of ficials for the next generation of design,

construction and facility management.

systematic use of BIM in the public in-dustrial market and also to set up the specific and practical standards of BIM application for each organization.

Public Procurement Service (PPS) is a professional governmental organiza-tion which executes all public procuring services including material purchases, fac i l i t y const ruc t ion contrac ts and management for the public sector in Korea. PPS is equivalent to the GSA in the US.

Pub l ic Procurement Ser v ice an -nounced “BIM guidance for applica-t ion” for the public competit ions and turn-key based constructions on Oc-tober 17th, 2010. BIM guidance is fo-cusing on reducing the burden in the market resulting from new technology adoption. The goal is to define submis-sion procedures and the scope of BIM at each design stage. PPS is also aim-ing at saving costs and boosting Green Construction in public area by requiring

BIM based building energy ef f iciency analysis, energy simulations and model based quantity takeoffs.

The long-term plan is to expand BIM into the entire public sector. Put in a very concrete way, the target is that by 2013-2015 BIM is applied on all turn-key design construction projects valued over $50 million, and achieving savings by using 4D cost engineering systems. By 2016 the target is that BIM is used on all public projects.

KPXDesignCompetition:BIMinPracticeIn the Korean Power Market there are six power generation companies and several power producers producing electrici ty. Korea Electric Power Cor-poration is in charge of transmission, distribution & retail of electricity. Elec-tricity is traded in the power market in Korea. The power market is the whole-

sale market for trading electricity pro-duced. Korea Power Exchange (KPX) is in charge of the market operations. Korea Power Exchange is a nonprofit or-ganization, which plays a pivotal role in South Korea’s power industry by ensur-ing the reliability of power supply in all regions of South Korea.

The new headquar ters was to be buil t under the mot to of an energ y saving and environment-friendly build-ing with innovative design. BIM was planned to be applied to the project over all stages from design, construc-tion, and facility management. Pushing ahead with a design project, KPX estab-lished the f irst ever BIM guidelines in Korea and decided to apply OpenBIM technology from the beginning of the project. KPX applied the national BIM guides by MLTM (The Ministry of Land, Transpor t and Mari t ime Af fairs) and spent more than one year set t ing up its own BIM design guidelines, which

constituted the basis for preliminary quantified quality evaluation of models in the IFC format.

OpenBIM based model checking sof tware was used for checking the space program, environmental friendli-ness and the economics of the design from the construct ion point of view. The primary goal was to pre-evaluate the designs and minimize subject ive opinion, at the same time introducing automated, systematic and a sensible evaluation process producing quanti -f ied and objective BIM quality results. One of the par ticipant companies stat-ed that “This was an innovative case, whereas the previous BIM evaluation processes have been subjective produc-ing ambiguous BIM evaluation results.” Solibri Model Checker was provided to every group so that the objective and reliable evaluation was guaranteed for all par ticipants and KPX.

HeerimArchitectsandPlan-ners:theWinneroftheKPXDesignCompetitionThe six design groups which took par t in the competi t ion where Heerim Ar-chitecs & Planners, Aum & Lee Archi-tects & Associates, GNI Architects & Engineers, Hyundai Architects & Engi-neers Associates Co., Samwoo Archi-tects & Engineers and Sang ji Environ-ment & Architects Space Group.

The winner of the competit ion was Heerim Architects and Planners Co., Ltd. The company is a publicly listed ar-chitectural and design service provider headquar tered in Seoul. The company is large, even on the global scale. The 2010 World Architecture 100 published as a supplement to Building Design ranked Heerim as Number 84 in the g lobal design communit y. Based on the number of design professionals, or creativity, Heerim was ranked eighth. And in the Pacif ic Rim, the company is number two in terms of income. The company has seen robust demand also from abroad including Abu Dhabi, Azer-baijan and Vietnam. Heerim specializes in cul tural facil i t ies, governmental, public and residential buildings, and spor ts stadiums. A winning proposal in a design competition where BIM quality is one criteria is a clear indication of

Heerim being a company willing to in-vest in the future.

BIMandQualityControlatHeerimArchitectsandPlan-nersBIM provides design companies with clear benefits. General Manager JuY-oung Lee from the BIM Research Group Archi tectural R&D Center at Heerim states that “For architectural design companies, BIM makes it possible to realize high-value design such as free form structure and helps to perform high quality design by ef f icient information management. BIM is also utilized as an ef fective educational tool for the staf f. By applying BIM, we could enhance the clients’ satisfaction level and keep the clear communication among the experts in each design team.” For Heerim this means that BIM makes it easy to per-form the various 3D design reviews

from the initial stage, and to avoid the design issues from the beginning. This minimizes the amount of design change and enables Heerim to recognize the potential issues in construction phase and set up the plans to handle them in advance. From the clients’ perspective BIM has increased the level of under-standing of their building. This allowed designers to communicate clients’ de-mand most effectively and fast. In ad-dition, it opened a way of get ting new ideas from the clients thanks to their experience in 3D vir tual space.

“Solibri Model Checker enabled us to per form automatic checks for de -sign and clashes between various dis-ciplines. Above all, thanks to SMC, it was possib le to integrate , evaluate and manage dif ferent data formats in the project , which enhanced overal l productivi t y signi f icantly. Especial ly, i t was very impressive to experience its excellent abili ty of processing IFC data.” continues JuYoung Lee.

The archi tec -tural f irm has 22 employees and is cont inually searching for innovat ive and sustainable concepts, develop -ments, ini t iat ives and collaborations using the Building Information Model.

WorkingTogetherDirector architect Ronald van Aggelen is delighted to talk about the new de-velopments: “It is increasingly important to share information with other partners in the building process. Not only does

that reduce failure costs caused by poor communication, it also optimizes our in-ternal processes. By using a BIM model and the exchange of transparent, unam-biguous data we are forcing ourselves to the limits to get the best from the model.”

“Specif ically for this project we are working with Vericon (consultant for bui lding structures), an experienced Tekla user and Veccins3d (installation consultant), a company which works with DDS-CAD. We agreed to collaborate in BIM and to monitor the quality of the provided information by an independent check on modelling- and design errors.”

SolibriasaunifyingfactorOver one year ago ZEEP architecten purchased Solibri Model Checker from Kubus archi tectural solut ions, their BIM-par tner and ArchiCAD-distributor. Af ter a test phase, they concluded that Solibri can be used on various projects: internal, small projects and bigger proj-ects in which collaboration is needed. Van Aggelen says Solibri is the ‘unify-ing factor’. He continues: “Solibri works

as a control system, we have no discus-sions about the quality of the informa-tion supplied by all parties. Solibri helps the team improve the quali t y of our work. It is an objective tool to monitor if the model meets predefined require-ments. It comes as no surprise that for our construction partners and us, it was an easy choice to implement the Solibri Model Checker into our joint project.”

“We also use Solibri Model Checker for budgetary control. The beauty of this sof tware is that even without coding during the process of elaborated design, all quantities can be extracted from the model.

The way in which the design is created is independent of the working method or the used software. We strongly believe in this OpenBIM way of doing things.”

OptimizationofdesignTaking off quantities and the coordina-tion between the various models pro-vided within the Solibri Model Checker are done by “rulesets”. To optimize the architectural design, the core business of ZEEP architecten, other types of ru-lesets are being used. As an example, Van Aggelen speaks about the assess-ment of using sur face areas, wheel -chair accessibili ty and control of the schedule of requirements.

The use of OpenBIM during the de-sign (ArchiCAD, Tekla, DDS-CAD, and So-libri) has ensured that within 6 weeks from star ting the design from scratch, the building permit was submitted. Van Aggelen: “A very quick turnaround, you can imagine that our client is very happy. We also ensured an end product with a higher quality than the sum of its parts.”

TrustisimportantVan Aggelen indicates that what they do on a small scale is also widely used. “It ’s not a matter of blind confidence in technology or in software. Cooperat-ing parties must confide in each other, which are accessed by what is produced in the light of pre-agreed conditions. Ru-lesets within Solibri makes clear what we are doing during the design process, which is essential in this modern era “.

This changing way of cooperat ion automatically leads to changing pro-cesses within the partnership. Here are two important factors according to van

Aggelen; his blue eyes and a proof of concept. “Construction partners are - al-most by nature - wary of each other. This has to be overcome and we have come a long way with our partners on this level. Although I of ten can be trusted on my blue eyes, my decisions are, since work-ing with Solibri, better founded”. All part-ners are aware of the benefits of doing business this way. Van Aggelen speaks of a breakthrough in the AEC-industry.

WorkflowThe star ting point in exchanging infor-mation between the various construc-tion par tners is IFC. All IFC-data sup-plied is stored in an IFC-server where Solibri is used as a shell. Solibri moni-tors the check on the quality of both in-coming and outgoing IFC files.

Solibri Model Checker has a central function and: • controls the technical quality of the IFC model; • regulates the coordination between different disciplines;

• provides the overall control of the building.

TraditionalcontractorandprincipalThe new construction project in Zwolle is in collaborat ion with a tradit ional working contractor. The principal usu-ally works as well in the tradi t ional manner because, as stated earlier, all par ties have confidence in working this way. The vision and approach of ZEEP archi tec ten have t ruly earned that both the client and the contractor will become convinced of this new way of working. Van Aggelen gives an example: “We are able, by the use of Solibri, to answer any question about the build-ing in approximately 10% of the time we normally spend. Think of detecting an amount of square meters frames of a particular type. The quantity takeoff of Solibri really proved a practical tool.”

The design is now ready for con-s t ruc t ion, market ing mater ials are made and the cons t ruc t ion docu -

ments will be manufactured regard-ing the spec i f icat ions of the con -tractor, direct ly from ArchiCAD. As a bonus, the cont rac tor receives di -rec t ly unsol ic i ted informat ion such as quantity surveys and costing data.

The ul t imate goal of van Ag gelen is providing an ‘as-build model’ of a house in the projec t . “Cer tainly we s t r ive for an opt imal improvement of our processes for which this proj -ect lends itself per fectly. And thanks to our new way of working, we even have spare time!”

HENT is one of the pioneers of OpenBIM in Norway and was the contractor for the front entrance building project at

the New Akershus University Hospital (New AHUS) between 2007 and 2008, one of the first OpenBIM pilot projects in Norway. The experiences were mixed and fur ther HENT deployment was put on hold. However, in the autumn of 2010 HENT did a new review of the state of the ar t of OpenBIM inspired by Rambøll, one of their design par tners and their VDC advisor. The conclusion was that OpenBIM was ripe for harves-ting. Solibri Model Checker has been an instrumental tool in HENT’s OpenBIM deployment effor t. Currently, more than 20 projects involving more than 300 people use Solibri Model Checker on a daily basis for improved project under-standing and quality assurance.

17CASE STUDY

Modelbaseddesign-“LeandigitalConstruction”A Building Information Model (BIM) – consists of digital materials, products or objects with proper ty information assembled into a building (model) . The let ters BM signif ies the visual 3D model and “I” the database with prop-er ty information.

The Designers get, with the help of BIM, a much better and holistic under-standing of the project. However, BIM and OpenBIM usage demands that the Designers need to plan the Design Work or the digital Construction Work to a much greater extent. HENT believes that Designers can learn a lot from the construct ion process with regard to minute planning and organizing produc-t ion processes – Lean Construction. They even think the Design Manager can be seen as a “Digi tal Construc-tion Manager”. HENT has coined their VDC approach “Lean Digital Construc-tion” or resource efficient model-based Design. What it means is that Design should be done in a smar t way, utiliz-ing Discipline specific building models, resulting in sustainable buildings de-livered on time, within budget and with zero defects.

A lot of architects and consultants have used BIM within their disciplines for drawing production for many years (closed-Discipline-BIM). In HENT proj-ects these models are re-cycled or uti-l ized through Open-Team-BIM/IFC to create a cross-disciplinary coordination model of the given project. By building digitally or vir tually - on the digital con-struction site - before the building is built in reality, contractors can quality assure and take away obvious design errors that normally are discovered during construction. Additionally, Open-Team-BIM is also valuable for project selling and 3D visualization. The adage “A picture is worth a thousand words” is also relevant for BIM. These are some of the reasons explaining the effective-ness and efficiency of BIM.

Because it was too time consuming and cumbersome to make 3D Models until recently, only 2D Drawings were produced and actually on some proj -ects are still produced. What has en-abled the AEC industry to take advan-tage of 3D modeling is the development

of improved sof tware and faster com-puters.

The advantages of using BIM is that HENT can 1) use models and per form analysis in early stage project develop-ment evaluating dif ferent scenarios to-gether with their customers. In Design HENT can 2) produce drawings more ef f iciently and ef fectively, 3) per form better spatial co-ordination and qual-i t y assurance, and 4) design faster. Construction can be involved earlier and contribute with insight in order to 5) improve the constructabili ty of de-signed solutions. Construction can also 6) train assembly or construction work-ers in the Model and 7) do production simulation or 4D simulation. BIM also enables HENT to bet ter structure the information f low on a project, so that they, through the use of BIM construct a database wi th information that is valuable as 8) FM documentation af ter commissioning.

HENT is currently among the leading construction companies utilizing BIM in Design – Lean digital Construction and in Construction – Lean Construction in Norway.

CaseAkerSolutionsnewOf-ficeBuildinginStavangerThe Office project for Aker Solutions AS in Jåt tåvågen in Stavanger has been

actively using BIM for drawing produc-tion and OpenBIM for spatial coordina-tion and quality assurance. One of the lessons learned is the impor tance of defining OpenBIM usage as an integral par t of the design process and not be too ambitious the first couple of times you use BIM and OpenBIM, but aim for the low hanging fruits.

The digi tal or vir tual construct ion site is also a key enabler for reducing the number of construction errors due to design errors or omissions in the construction documentation.

The HENT Project Manager Thom-as Grøt tvik states that to execute an OpenBIM Project, as HENT does on this project, involves “doing the construc-tion job” on the PC before it is done at the construction site for real. Deploy-ing Solibri Model Checker as a Quality Assurance Tool has as an ef fect that at least 80 % of the design Errors and Omissions, which earlier were discov-ered as errors on site during construc-tion, now are identif ied and solved in the Design Process. One error at the PC is much less expensive to correct, while an error at the site of ten involves a lot of hassles, delays and money spent. This also has as a consequence that we can manage and control the design progress much better. In addition, the OpenBIM Model is a good aid for com-municating design intent and improv-

ing communication and understanding across disciplines in the design team. On this project, the OpenBIM Model has also been used by the construction crews for planning actual construction work.

HENT is also building new offices for Aker Solutions in Oslo. At the two sites, in Oslo and Stavanger, Open BIM has worked as a tool for QTO control, spa-tial coordination, production planning and general problem solving.

CaseHasleveienKindergarteninOsloThe old Foundry building at Hasle in Oslo is transformed into a 306 children kinder garden. The project is on the Cultural Heritage List so there is close cooperation with the Office of Cultural Her i tage Management . The Projec t consists of both new construction and renovation Work.

On the project, OpenBIM has been used for drawing production, visualiza-tion and to perform environmental anal-ysis, especially focusing on lighting.

CaseDPO5–NewEmergencyCareUnitatOsloUniversityHospitallocationUllevålThe Health Region of Oslo (OUS HF) is being reorganized, and as par t of this the emergency care unit is also being reorganized. A new unit with several operating theaters is currently being developed. The reorganized unit will be one of the largest emergency care units in all Scandinavia. OpenBIM and Solibri Model Checker have been used in the early phases in programming and for quality assurance and spatial coor-dination, with success.

19SOLIBRI MODEL CHECKER

ProcessPerformanceWe are commit ted to continuous per-formance gains and delivering the most versatile capabilities for the Quality As-surance/Quality Control (QA/QC) pro-cess. This allows us to of fer the mini-mum total cost of ownership for BIM analysis sof tware while achieving the maximum speed of delivering consis-tent quality. If you just check part of the model or just one aspect, how can you tell the quality of the unchecked items? Our philosophy is that we check the en-tire building each time, the same way, allowing us to obtain objective check-ing results. Results can of course then be filtered - in many ways. Issues that are found need to be communicated, fixed and verified before we are done.

The total process per formance has been improved in many areas:• Streamlined user inter face is even easier to use : This = a reduced learning curve (cost)• New menu structures maximize the available working area: more content

IntroducingRolesSolibri Model Checker v7 comes with preset roles such as: Training, Archi-tect, Building Code Checking, Energy Analysis, MEP, Structural, BIM Coordi-nator, QTO, Owner, and Admin. These can be modified and you may define as many new roles as you need.

The general idea is to have recom-mended rulesets, c lassif icat ions to match, and ITO def ini t ions for each role. This way it’s easier to f ind what is needed and using Sol ibr i Model Checker v7 is more efficient, providing just what is required to the end user. No more, no less. Fur ther, you can set defaults (yellow stars) to be used each time you open a new model.

20 SOLIBRI MODEL CHECKER

SupportforEnterpriselevelQA/QCPracticesandProcessesBy providing tools for managing shared resources, such as QA/QC specific rule-sets, rule parameters, ITO’s and classi-fications, Solibri Model Checker v7 now better suppor ts the organization-wide implementation of BIM QA/QC methods and best practices. Users can be as-signed either the standard user profile or admin user profile. Design profes-sionals can now follow their company’s model checking practices.

User rights may also prevent individ-ual standard users from modifying ru-lesets and parameters and potentially deviating from the company’s desired practices .

Implementing the standard BIM QA/QC process is carr ied out by admin users. This also allows for a shared centralized repository of rulesets and classif ications for ef fectively sharing, updating and managing company level Solibri installations, reducing IT costs. By default, Solibri Model Checker relat-ed files are saved locally on each user’s computer. In version 7 it is possible to define centrally, with one configuration f ile, where dif ferent resources are lo -cated. For example, from which folders the user should look for rulesets, IFC models, ITO definitions and templates, etc. This configuration file is stored in a shared folder, and each Solibri Model Checker installation points to the same file. This simplifies the maintenance of Solibri Model Checker installations and eases distribution of company or proj-ect specif ic resources allowing each user the access to same files.

DramaticallyImprovedPer-formanceBIM is becoming more and more widely adopted, and BIM has reached the ma-turity to suit even the biggest and most demanding projec ts . Sol ibr i Model Checker v7 per formance has been greatly enhanced, and the speed and accuracy Solibri provides to the appli-cation of BIM even on the largest proj-ects: • Load t ime reduced up to 40% as compared to version 6.2• Fo o t p r in t re du c e d by 6 0 % a s compared to v6.2• 3D Performance, especially frames p e r s e c o n d , h a s b e e n h i g h l y improved e sp e c ia l l y w i th large models

RuleDependencies,Interre-latingRulesThis feature enables rules to depend on the results of another rule. A simple example is that when you are checking Accessibili t y you f irst have to check that your model has spaces classified. If this is not the case, then other rules will not produce any issues since the only issue is the proper space classi-fication.

NewRulesLately we are seeing many BIM guides being developed. GSA BIM Guides in the US are continuously developing, Statsbygg is about to publish their BIM Manual in Norway, as well as the Na-tional BIM guides in Finland. These are

now included as rulesets in SMC, with more to come.

We are working on many fronts in the area of Building Code Checking. Now we have rules for accessibili ty according ISO CD 21542, ADA, ABA, ICC and Finn-ish Standards. Egress rules have also been fur ther enhanced.

These are some examples of the new rules and rulesets added to this version.

BIM adopt ion is spreading through public organizations and pr ivate companies in the AEC industries. The tar-

get is to benefit from BIM by creating a competitive advantage, and of ten in the public sector achieve more with less because of the pressure to make budget cuts. Adoption and BIM maturity is driven by organizations that develop both intra-organizat ional processes and set requirements to actors in the construction business value network.

Development tak ing p lace today ranges f rom draf t ing nat ional BIM guidelines (or standards) to developing organization specific BIM guidelines in either public organizations or private enterpr ises. The target is common however. Once BIM guidelines and re-quirements are in use they must be fol-lowed.

This will mean that design suppliers will need to be able to provide their cli-

BIM Maturity:The Second Generationents with the models they require, and invest in learning to model in a way which fulf ills their needs and require-ments. BIM will be the way to work, not unlike the t ime when a drawing skill used to be necessary for drafting struc-tural details.

From the point of view of the AEC sector, there will be those who can, and those who cannot. For those who cannot, the inability to understand and execute within a BIM environment will limit the possibility to take par t in con-struction projects, thereby diminishing the possibili t ies to at tract new busi -ness.

will be to develop vacated state-owned premises for alternative utilization.

The buildings must meet quality re-quirements per taining to architecture, functionali ty and environmental con-cerns. This is where BIM comes in.

Statsbygg Building Information Mod-eling Manual Draf t (herein SMB) con-tains Statsbygg’s generic requirements for Building Information Modeling (BIM) in projects and at facilities. SBM is in-tended to describe Statsbygg’s require-ments for Building Information Mod-els (BIM) in open Industry Foundation Classes (IFC) format. SBM categorizes requirements as mandator y, recom-mended, optional, or reversed (a re -quirement for something that must not occur). SMB describes both basic and generic BIM requirements, and generic model structure requirements.

All requirements are numbered. Re-quirement No. 4 states that “A digital 3D building information model based on object based design (using objects with properties and relations) and using open BIM standards/formats is a main deliverable.” Requirement No. 6 states that “The BIM authoring tool must ef-f iciently suppor t impor t and expor t in the open Industry Foundation Classes (IFC) BIM format”. Both requirements are mandatory. A point wor th noting is that Statsbygg requires OpenBIM to be used, permit ting enhanced collabora-tion and flow of information between all stakeholders based on open standards. For example, requirements for spaces require that spaces shall be modeled with 3-dimensional space objects. As we can see, being able to perform only clash detection is totally inadequate.

Statsbygg as a client will in most cases provide a “Requirement BIM” that basically contains the spatial pro-gram’s required spaces, func t ional grouping of the spaces, and any re -quirements that are defined for each space, group, or accompanying furni-ture, f it tings & equipment. In addition to basic requirements, SMB specif ies BIM design requirements by discipline and design phase from conceptual de-sign to coordinated design.

Statsbygg Building Information Mod-eling Manual also specifies cer tain QA/QC requirements including consisten-cy check, verif ication of design area, clash detection and coordination. Ad-

dit ionally, SMB outlines how to make a good model. In practice, SMB sets the standard for BIM, and defines what is expected from building information models, what is a good model and ef-fectually defining how to build a BIM, advancing BIM maturity even fur ther in Norway.

Based on the practical experience gained in Finland, i t is probable that SMB will also be used by municipal or-ganizations and applied in construction projects in the private sector. In effect, SMB is positioned to advance common culture and best practices for applying BIM in Norway in the whole AEC field.

CaseFinland:NationalBIMGuidelinesSenate Proper t ies is a government owned enterprise under the Finnish Ministry of Finance. Senaatti is respon-sible for managing the Finnish state`s proper ty assets and for leasing prem-ises. In 2010, the proper ty por t folio included 11,700 buildings, totaling an area of 6.6 million m2 and valued at EURO 5.2 billion.

Senate Proper t ies prov ides ser-vices related to premises. The primary customer is the state administration.

Senaat t i 's ser v ices include leasing premises, investments, and the ad-ministrat ion and development of the proper ty por tfolio. Senate Proper ties f inances its own operations and is in-dependent of the state budget. The proper ty por tfolio comprises cultural, of f ice, university, research, and other buildings.

Senaatti already published BIM Re-quirements and Guidelines in 2007. Since then, they have been adopted and used widely, influencing BIM adop-tion not only on the project’s related to maintaining and developing the state proper ty por tfolio, but also on munici-pal BIM adoption and practices imple-mented in the private sector. For sev-eral years, Solibri Model Checker has included Rulesets for checking model conformance with Senaat ti’s require -ments.

The industrial problem which Finland faced was that while modeling was ad-opted at an increasing pace in the con-struction value chain, several actors, such as major construct ion compa-nies had created their own guidelines while others, such as major cities and building owners were in the process of preparing their own. At the same time, many realize that they need to move to-

23BIM

ward modeling, but did not know how. Also authorit ies need to improve the handling and processing of building permits.

The solution to the above industrial problem was that, because Senaatti’s modeling guidelines needed to be up-dated and taken fur ther, Senaat t i’s present requirements would form a baseline. This process would be elevat-ed to the national level. Today Finland is in the process of creating The Na-tional BIM Requirements. They will be completed in the near future.

The target is to have one unif ied approach for BIM projects and a large national acceptance. National require-ments enable high market penetration and more information rich models. Also better models lead to enhanced infor-mation transfer within the construction value chain, and to a higher BIM matu-rity on the national level.

CaseUS:GSAThe United States General Services Ad-ministration (GSA) provides and main-tains workplaces through the Public Buildings Service (PBS). PBS maintains an inventory of more than 370 million square feet of workspace for 1.1 mil-lion federal employees. PBS acquires space on behalf of the federal govern-ment through new construct ion and leasing. In ef fect, PBS is the landlord for the civilian federal government in

the US. One key business function PBS per forms is the planning, design, and construction of new and modernized border stat ions, cour thouses, of f ice buildings, and other facilities.

As early as 2003, GSA established t he Na t iona l 3D - 4D - B IM Prog r am through the PBS, Office of Chief Archi-tect. GSA pointed out very early that “Crit ical to successful integration of computer models into project coordina-tion, simulation, and optimization is the inclusion of information—the “I” in BIM—to generate feedback.” GSA also point-ed out very early that 3D, 4D, and BIM technologies represent three separate ways in which computer technologies can aid building owners, such as GSA, to manage their facili t ies throughout the whole lifecycle. Building Informa-tion Models include, in addition to 3D geometric models, specific information on the building elements and systems within a building.

Examples of the information include wall types, spaces, air handling units, spat ial informat ion, and circulat ion zones. It is not enough that informa-tion is included in the building. It must be possible to takeoff information from BIMs, safely. Information to be used for decision-making must be correct so business decisions are based on reli -able information, which reduces data-based risks, such as incorrect rentable area information or building component

quantities, affecting cost estimates or investment decisions. The approach GSA has taken is very much in the heart of BIM. Building Information Models are used for spatial validation, accessibil-ity, egress and circulation analysis, and also for f inancial estimates. The infor-mation quali ty is paramount. Models must be checked for quality.

SolibriModelCheckerv7Solibri is actively par ticipating in sev-eral projects that relate to QA/QC so-lutions and processes. In the US, the FIATECH sponsored AutoCodes project is an example of Solibri’s commitment to delivering consistent quality to the global building code checking and re-view process (Please read the related selection in this magazine). In Korea, the Solibr i Model Checker has been used for evaluating BIM quality for pro-posals in design competitions. For the European AEC community, Solibri has implemented suppor t for the upcom-ing Statsbygg BIM Guidelines and the Finnish National BIM Guidelines being prepared. When these Guidelines are put into use Solibri Model Checker v7 will include support for BIM QA/QC pro-cesses and best practices for BIM on a large scale.

Nat ional , government leve l , and company leve l B IM guide l ine s are being adopted and used widely by the AEC community. This is the sec-ond generat ion of BIM. Already sup-ported by Solibri.
