1 VIRTUAL PROTOTYPING FOR THE AEC INDUSTRY

2 VIRTUAL PROTOTYPING FOR THE AEC INDUSTRY Virtual Prototypes in AEC are a combination of 3D/ BIM and Virtual Reality. In combination, 3D/BIM and VR opens up for 1:1 scale workflows troughout all phases of construction projects. By adding this new dimension to projects, stakeholders get a common and precise understanding of area, space and function. Virtual prototyping and 1:1 scale is not only applicable to building projects, but also for city planning and infrastructure projects like roads, bridges and tunnels. The results of Virtual Prototyping has significant impact on project budgets for construction and operations of facilities. Implementing virtual prototyping on construction projects has a positive impact on project budgets. By doing so, it is important to add proper time for test and analysis in the projects early phases. Based on facts of costly errors in the schematic and design development project phase from traditional 2D methods, the AEC industry now face a time where more time is spent in the early phase of the project. More frequent iterations between project owner, consultants, users, authorities, contractors and facility managers result in lower cost for constuction and operations. Savings are highest in the early stages of the project. VIRTUAL PROTOTYPE USE SCENARIOS CITY PLANNING: Infrastructural planning of cities based on 1:1 scale virtual prototypes creates high level of value for authorities, project owners and citizens. PROGRAMMING: Analysis of planned area and functions in the initial stage of a project, where room size, function and placement can be tested. CO-CREATION: Involve users in the early design phase and create guidelines for design layouts as well as early logistical analysis. TEST & ANALYSIS: Project stakeholders and users test and analyse the project in 1:1 scale. The project is updated for each session in order to optimize area, space and function. WAYFINDING: By utilizing the virtual prototype for wayfinding buildings and their surroundings are optimized with signs and marked up areas. PRE-USE TRAINING: The virtual prototype also becomes an important tool for preparing the operational phase of buildings, where virtual reality and gamification makes it possible to create training scenarios, that becomes critical once the project becomes operational. OPERATIONS: By utilizing as-built models in 1:1 scale in the operational phase, virtual prototypes also become usefull in relation to staff trainings, education, work environment, safety as well as planning of future re-build projects. COST AND CONSEQUENCES OF PROJECT ERRORS: 1. Design: Fast to implement changes. 2. Detailing: Takes longer to change. 3. Tender: Impacts on contracts and planning. 4. : Impact on planning, pocurement and site works. 5. Operations: Where solutions worst case needs to be rebuilt. $10,000 Operations $1,000 QUALITY IN DESIGN DEVELOPMENT: Based on the 1:1 scale ability and the group based sessions in VR studio and the interaction between consultants, operators, contractors and authorities further secure increase quality and enhanced functionality in buildings. $100 Tender $10 Detailing $1 Design

3 PROTOTYPING WORKFLOW Comparing the traditional project process with VIRTUAL PROTOTYPING, it becomes clear that the early phase of a project is where the value from prototyping is created. Virtual Prototypes opens up for quality iterations and high level of interaction between stakeholders. Real cost is known prior to construction and site work, as well as improved possibilities for optimization of the operational phase of facilities.

4 CASE: SWECO CASE: PANUM 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 m 2 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 nancial 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. 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 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 Virtual 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 Jaakko Jauhiainen Director Business Development, Sweco PM Ltd 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. 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. Sweco truly believes that the correct design, design management & coordination, and sound construction will achieve lower life cycle costs. Furthermore procurement and con- struction 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. 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 In our user meetings, we use a lot of resources to get the worlds of consultants and users to meet. In the 1:1 scale virtual prototype we enhance our communication based on real understanding between consultants, users and project owner. In our iterations in 1:1 scale we create savings on costly project resources consultants plan drawings. Therefore, communication, coordination and intermediary co-creation and design reviews are some of the factors that are critical to the project outcome. Gert Pedersen Project Manager Campus Service Sund To ensure communica- tion, knowledge sharing and transparency in the project, the Danish Buil- ding Authority deman- ded 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 cor- rect 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.
