1 VIRTUAL PROTYPING FOR THE AEC INDUSTRY

2 VIRTUAL PROTYPING FOR THE AEC INDUSTRY WHAT IS A PROTOTYPE IN THE CONSTRUCTION INDUSTRY? In the construction industry, there is a great need to improve the processes that are instrumental for realising a construction project. Many parties are involved and this often turns the construction project into a complex process that needs to be managed throughout from the preliminary stage to the main project, implementation and subsequent operation. Unlike the building industry, in other industries people have worked using prototypes for testing, analysing and thereby optimising products before they are put into production. The preconditions for doing this are not entirely the same in the construction sector compared to e.g. the automotive industry, which has a production line under one and the same roof. Before a company in the automotive industry begins producing a new car model, many years of design and engineering development already exist, during which 3D software has been utilised to design and also scale 1:1 technology for testing, analysis and optimisation before building a test model. This is the point where car manufacture differs significantly from the construction industry, where the test model can only be built to a smaller scale. However, there is great potential in the construction industry to utilise the same methods as the automotive industry during the planning and project design phase of a construction project. This is where 3D-models from the project s professional consultants could be utilised as the basis for developing virtual prototypes that correspond to the prototypes used in car design. This is beginning to happen to a certain extent, but without going all out and creating We believe that correct design management in combination with user involvement and proper coordination for construction will achieve a more efficient use of project budgets. The long term effect of our project workflow results in better solutions and lower life cycle costs for hospitals and healthcare projects Jaakko Jauhiainen Director Business Development, Sweco PM Ltd a virtual prototype that can become the project s database for information and the sub-processes which help to create a building that lives up to the planned expectations regarding budget and subsequent operation. THE DEVELOPMENT OF THE CONSTRUCTION INDUSTRY The development of the construction industry over the past decade more and more highlights the value of designing in 3D. A large number of CAD systems have been developed specifically for this purpose what is known as BIM software (BIM stands for Building Information Modelling), where consultants use the tool to create the virtual prototype within their own area of expertise. A constellation of consultants who all have the tools and competence to work in BIM is the first step on the road to creating a complete prototype for the entire project. But a construction project does not only comprise different types of consultants; there are also developers, users and contractors. To be able to utilise the advantages of virtual prototypes there must be a common understanding of the value that this adds to the project and everyone involved. This understanding forms the basis for the revised terms of reference between the involved parties, which in turn leads to expanded timelines during the project s early stages. This is a basic precondition to be able to create and utilise the advantages of virtual prototypes. $10,000 $1,000 $100 $10 $1 Use Contractor Tender Detailing Design THE COSTS AND CONSEQUENCES OF PROJECT ERRORS On the basis of the complex composition of different parties and their individual interests, developments in the industry are moving far too slowly. This is due to the terms of reference that have been drawn up over time, based on the old method where projects were carried out on the basis of manual calculations, hand-drawn sketches and 2D drawings. With the new technology, in which 3D and BIM are used as the basis for creating the virtual prototype and thereby building a database of information, a change of method has taken place. This change of method also leads to a new project design process, and this should therefore be reflected in the terms of reference. If this does not happen, there arises a relationship between developers and consultants/construction managers which has the sole aim of safeguarding the legal agreements, without taking account the benefits inherent in the change of method and the creation of the virtual prototype. Adapting the terms of reference to the new method leads to added value for all parties. The developer does not only get a project that can be built according to the planned budget, but also a building that functions well in operation. Consultants are paid based on their efforts to create the prototype, which in turn gives the contractor accurate information when it comes to completing the project within the agreed timeframe and budget. THE ECONOMIC VALUE OF CREATING VIRTUAL PROTOTYPES What then are the consequences of the errors that arise during construction and what can the industry win by using the new methods of BIM and virtual prototypes? We are all aware of the consequences of such errors; projects are halted at the construction site due to one or more design errors, which thus postpones schedules and impacts on costs for producing new building components and the like. Even worse is the example of a completed building that must be rebuilt because its functionality does not live up to the operational requirements, thus requiring rebuilding. Continue reading >>

3 CASE VIRTUAL PROTYPING FOR THE AEC INDUSTRY It will be possible to avoid situations like this by creating 3D/BIM models that can be tested, analysed and optimised thereby creating a virtual prototype. This can be used to generate information for planning, procurement, implementation and operation.

If this workflow does not meet the criteria for how to continuously create more information in the database for the project, it will compromise the quality that is critical for whether the virtual prototype ends up creating value or not. Information is created across the project through the use of a well-developed workflow and the methods this entails, which at the same time builds a value chain from the first sketch to operation and maintenance. This BIM Workflow Guide is not only a tool for consultants and contractors, but at the same time a manual for developers/entrepreneurs in regard to drawing up terms of reference for construction projects. By defining the method as well as the agreement process for the project design, implementation and delivery, the preconditions for drawing up the virtual prototype for the project are created. THE VALUE OF VIRTUAL PROTOTYPES THE PROJECT IN VIRTUAL 1:1 SCALE The developments within 3D/BIM in the construction industry have gone hand-in-hand with the gaming industry, where the industry now meet by using 3D/ BIM files on gaming-based platforms. Combined with 3D units such as OpenBIM Studio and 3D glasses, this makes it possible to create 1:1 scale views generated from the 3D/BIM project. THE RESULT OF THIS IS VIRTUAL PROTOTYPES IN 1:1 SCALE. It is the level of detail of the 3D/BIM project that determines the level for the virtual prototype in the 1:1 scale view. In order to achieve the full effect of the full-scale in the project, it is therefore important to make use of 3D/BIM as early as possible in the project phase. The utilisation of 1:1 scale therefore runs parallel to the BIM process and creates value throughout the whole project. Right down to the sub-processes where BIM does not presently add value to the design, implementation, commissioning and operation of the building. Virtual prototypes do not only create value for the project partners. They also do so across the entire project, where the project in 1:1 scale provides a common understanding for the developer, consultants, users, contractors and operators. This hereby creates the transparency needed to optimise the project so that the building s function is thoroughly tested and analysed, which results in future-proofed buildings. The virtual prototype is where the really big savings are hereby found in the project design and construction phase, as well as in the subsequent operation. PANUM In recent years the building owner invest heavily in the Faculty of Medicine at the University of Copenhagen with the expansion and modernization of Panum. The modernization project consists of both new construction and overall renovation of selected areas. The renovation of Panum consists of a highly complex interaction between installations, joint buildings with advanced equipment. At the same time several advisors work coordinated while different needs of users are met. Even with competent consultants and close control from both the Danish Building Authorities and the project team from University of Copenhagen, there are many sources of errors. Errors that can potentially increase the cost of the renovation considerably - whether errors are caused by lack of coordination between disciplines or lack of understanding for future use, or as often is the case: the future users have difficulty understanding consultants plan drawings. Therefore, communication, coordination and intermediary co-creation and design reviews are some of the In our user meetings, we use a lot of resources to get the worlds of consultants and users to meet. If sessions in OpenBIM Studio can save the whole team just two meetings, enhancing the communication and understanding between consultants, users and developers, I see many opportunities to use OpenBIM Studio. Projects will be better, while we save resources Gert Pedersen, Project Manager Campus Service Sund factors that are critical to the project outcome. To ensure communication, knowledge sharing and transparency in the project, the Danish Building Authority demanded that the project was developed with Building Information Models (BIM). These BIM models are now also used to ensure that future users will have proper facilities with correct functions by working in virtual 1:1 scale. The project team at Panum decided to utilize the 1:1 scale ability of OpenBIM Studio, where project managers, consultants, healthcare staff, the Danish Building Authorities and union representatives now test and analyze the building based on the developed virtual prototypes.

5 CASE SWECO Sweco is a leading technical consultancy company and employs 14,000 experts serving 17,000 clients annually on 42,000 assignments. One important work area sector for Sweco is healthcare projects. When building healthcare facilities, the logistical needs are complicated and operating costs easily increases with less efficient solutions. Inefficient solutions result in higher operational costs for owning, operate and maintain buildings. At the same time, the population is growing older, and the scarcity of resources compel the public sector to make both ends meet, achieving more with less. ALLIANCE PROJECT: A JOINT EFFORT Sweco Finland is currently working on the Kajaani New Hospital project, a regional m2 healthcare facility with a budget of 103 million euros for design and construction. The project is the first hospital project in Finland to use project alliance - a novel project delivery method based on a joint contract, where the parties (design companies, contractors and the client) assume joint responsibility for the design and construction of the project. The stakeholders share both positive financial impact and negative risks related to the project. In the Kajaani New Hospital project the project alliance is formed by Sweco Architects, Sweco PM, Sweco Structures, Sweco Systems, Skanska and Caverion. SWECO DESIGN WORKFLOW Realizing the dilemma clients face today, Sweco has created a novel design workflow, which significantly reduces the problems typical of healthcare projects. Compared to the traditional project process, the Sweco@Co-creation process starts off with an intense initial design process where all the stakeholders participate in the design. The initial stage is about requirements planning. The second phase is the schematic design where the actual design starts. All stakeholders participate in this phase in order to assist the selection of the design alternatives for design development. Simultaneously Sweco s structural and building services engineers collaborate with the architects optimizing the basic design choices for structures and HVAC systems. IFC and Solibri Model Checker are used for design coordination and BIM quality management. The result is a precise BIM model conforming to the Finnish Public BIM requirements.

6 CASE SWECO CAVE: RELIABLE AND UNIQUE DESIGN VALIDATION Using the BIM model, Sweco has created a very unique method for validating the design by the future users. Based upon the fact, that the majority of people are incapable of comprehending traditional plans and reviewing their quality, and that 70% of the understandability of a plan is lost if the plan is not presented in 1:1 scale, Sweco has created a user-centric design process employing C.A.V.E. (Computer Aided Vitrual Environment) visualization technology, which allows users to experience the space and move in a true, life-size 3D environment created through stereoscopic imaging in 1:1 scale. Sweco s design process and the visualization render the virtual building real making it possible to evaluate and review the quality of the design and produce reliable feedback for enhancing the design. The feedback Sweco receives from the users is much more valuable and credible, thus improving the decision quality and design review feedback. Sweco s design process also helps in reaching the hard project targets such as time schedule and budget. Also, Sweco uses agile design management methods helping Sweco to meet demanding design schedules. The design is broken into design-packages based on the construction need with specified handoffs and deliverables creating a predictable and tightly controlled workflow. At Sweco Architects Finland, we have a goal to create hospitals that support efficient and modern treatment processes, by lowering operational costs. We do this by involving doctors, nurses and service staff in our design processes, creating both a healing environment for patients and an inspiring workplace for the hospital organization BENEFITS FOR ALL STAKEHOLDERS Sweco strives to get the clear picture of how the users - patients, visitors and the staff of the building feel in the designed environment and utilize their opinions in the planning stage. The goal is to create hospitals that support efficient and modern treatment processes lowering operational costs, and both a healing environment for patients and an inspiring workplace for the medical staff. Jaakko Jauhiainen Director Business Development, Sweco PM Ltd Sweco truly believes that the correct design, design management and coordination, and sound construction will achieve lower life cycle costs. Furthermore procurement and construction will be efficient. The C.A.V.E. technology in combination with Sweco@ Co-creation, results in enhanced processes for testing and analysis, which leads to better projects in terms of expected quality, and agreed time schedules and budgets.
