Collaborative site layout planning using multi-touch table and immersive VR
- 2023

Ingår i: CONVR 2023 Proceedings of the 23rd International Conference on Construction Applications of Virtual Reality. ; 23, s. 81-90

Konferensbidrag (refereegranskat)abstract
- Building Information Modeling (BIM) is changing the way architects and engineers produce and deliver design results, and object-oriented 3D models are now starting to replace traditional 2D drawings during the construction phase. This allows for a number of applications to increase efficiency, such as quantity take-off, cost-estimation, and planning, but it also supports better communication and increased understanding at the construction site by means of detailed 3D models together with various visualization techniques. However, even in projects with a fully BIM-based design, there is one remaining part that is still done primarily using 2D drawings and sketches – the construction site layout plan. In addition to not take advantage of the benefits offered by 3D, it also makes it difficult to integrate site layout planning within the openBIM ecosystem. In this paper we present the design and evaluation of a user-friendly, IFC-compatible software system that supports collaborative, multi-user creation of construction site layout plans using both multi-touch table and immersive VR. By allowing temporary structures, machines, and other components to be easily added and updated it is possible to continuously produce and communicate 3D site layout plans that are aligned with the schedule and supports integration with other BIM-tools.

Konferensbidrag (refereegranskat)abstract
- This paper presents a system that allows immersive visualizations to become a natural and integrated part of the current building design process. It is realized through three main components: (1) the Oculus Rift - a new type of Head Mounted Display (HMD) directed at the consumer market, (2) a real-time rendering engine supporting large Building Information Models (BIM) that is, (3) implemented as a plug-in in a BIM authoring software. In addition to provide details regarding the implementation and integration of the different components in our system, we present an evaluation of it from three different perspectives; rendering performance, navigation interface and the ability to support fast design iterations.

Identifying And Developing Prerequisites For Takt Planning In A BIM-Based Construction Process
- 2023
-
Ingår i: Managing the digital transformation of construction industry.
-
Konferensbidrag (refereegranskat)abstract
- The construction industry is undergoing a significant shift in how design and production are conducted. Building Information Modeling (BIM) has emerged as a key tool for coordinating information from all involved disciplines and providing a more holistic view of the construction process. However, effective coordination and communication between different professions remain major challenges that require new approaches to project management. Takt planning has gained increasing attention as a potential solution to improve traditional planning methods. Despite this, there is a lack of real-world studies exploring BIM and takt planning where information is structured according to takt planning. A takt planning structure for all BIM-models would bring a more holistic understanding of what is to be done, controlled, and reported back. To address this gap, this paper presents findings from a three-stage research process. Firstly, form a focus group of disciplines to find a shared structure to present the execution in a common way for design and construction in a lab environment at a conceptual level, secondly implementing it to the detailed design information for real -world case project in workshops and group meetings with the focus group and then thirdly, evaluate it in the case project with the site staff involved. The findings highlight the importance of a shared denominator to get a holistic approach to project management and enabling takt planning throughout all phases of construction, providing insights into its practical application and benefits for the construction industry.

Etapp II: Virtuell Produktions Planering - med hjälp av BIM och visualisering.
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport presenterar resultatet från en genomförd FoU-projekt och forskningsstudier (teknisk licentiat) som undersöker möjligheten med att en ny planeringsmetodik dvs. Virtuell Produktions Planering (VPP). Planeringsmetodik utgår från en existerande strukturplaneringsworkshop process. Avsikten med planeringsmetodiken är att få olika delaktiga aktörer i projektet att samarbeta och utnyttja varandras kunskap och erfarenheter genom att gemensamt virtuellt bygga och planera produktionen av byggobjektet innan det verkställs i verklig produktion. VPP utnyttjar 3D-visualisering och BIM-modellen och dess information under denna process. Arbetsordningen för denna planeringsprocess är följande: • BIM-modellen och dess komponenter från projektering grupperas efter yrkesgrupper dvs. vem som har ansvaret att installera/bygga dessa under byggproduktionen. • De olika ansvariga yrkesgrupperna får sina tilldelade komponenter som de tid- och resurssätter. • Modellen och dess komponenter planeras och byggs sedan ihop digitalt i rätt ordning gemensamt av de olika involverade yrkesgrupperna och resultatet är en tidplan som kan visualiseras i 4D. Studien i denna rapport visar att det finns stora möjligheter till en effektivare planeringsprocess med VPP. VPP-systemet som tagits fram i studien har visat att det är tekniskt möjligt att implementera ett VPP-system. Vidare visade observationsstudien från fyra strukturplaneringsworkshopar på utvecklingspotential av den befintliga processen. Observationsstudien visade även att denna typ av workshop ger bättre: • granskning och identifiering av felkällor i projekteringen • testning och granskning av byggbarhet av projektet • sammanförande av kunskap och erfarenheter från projektering och produktion • laganda och Team-building för projektet • gemensam målbild och målplan I slutändan skulle VPP med största sannolikhet tillföra ökad tillförlitlighet och effektivitet i produktionen.

Konferensbidrag (refereegranskat)abstract
- The design process of a building often involves many different actors and people with different experiences, level of knowledge and ability to interpret information. The most common information media in these processes are 2D-drawings, documents and 3D images of design. These media can be difficult to interpret and understand and could cause communication difficulties and design errors. However, in this context, Building Information Modelling (BIM) and Virtual Reality (VR) have been shown to offer an efficient communication platform. In this paper we present and evaluate a portable immersive visualisation system that uses the BIMs directly from the design tools. The system is validated in a real construction project, where the different disciplines in the design process used the system. The result was collected through interviews and observation during usage of the system. All the participants expressed that this type of visual interface helped them to get another level of understanding and perception of space, which lead to better decision-making process and resolving of design issues.

Konferensbidrag (refereegranskat)abstract
- During the design of a new hospital, many different stakeholders are involved. These types of complex projects require more knowledge than any single individual possesses and in this context, it is necessary for all involved stakeholders to understand, participate, communicate, and collaborate with each other to obtain a high-quality outcome. This paper presents a collaborative design system, which support these creative and shared design processes. The presented system, Virtual Collaborative Design Environment (ViCoDE), features a seamless integration of a multi-touch table and several immersive VR-systems that support interactive and collaborative design work. The system has been evaluated during two studies in a real-world context of designing new healthcare environments (e.g. operating theaters). The results show that involved stakeholders better understand, participate, communicate, and collaborate with each other and that the multi-touch table and VR-system complement each other by facilitating different design spaces—both collaborative, as well as individual.

- The use of Virtual Reality (VR) and interactive real-timerendering in urban planning and building design are becoming moreand more common. However, the integration of VR in the urbanplanning process suffers from the complicated interaction handling ofthe virtual environment. In particular, people unfamiliar to gamingenvironments and computers are less prone to interact with a VRvisualization using keyboard and mouse as controlling devices. Thispaper addresses this issue by presenting an implementation of theXBOX 360 Kinect sensor system, which uses the human body tointeract with the virtual environment. This type of interaction interfaceenables a more natural and user-friendly way of interacting with thevirtual environment. The validation of the system shows thatrespondents perceived the interface as non-demanding and easy to use.The implemented interface to switch between different architectureproposals gave a better understanding and spatial reasoning for therespondent. The study also shows that males perceived the system asmore demanding than females. The users also associated andcompared their body with virtual environment, which could indicatethat they used their body during spatial reasoning. This type of spatialreasoning has been agued to enhance the spatial-perception.

Tidskriftsartikel (refereegranskat)abstract
- Throughout the design of a new building it is essential that all involved stakeholders understand, communicate, participate, and collaborate with each other to acquire a high-quality result. To support these shared and creative design processes, this paper presents the design and evaluation of virtual collaborative design environment (ViCoDE) - a new collaborative design system. ViCoDE features seamless integration of several immersive VR systems and a multitouch table that facilitates collaborative and interactive design work with immediate feedback. The evaluation of the system has been done during two real-life collaborative design workshops in a context of designing new healthcare environments. The results show that the VR system and multitouch table complement each other very well by facilitating both collaborative, and individual design spaces - and that it fosters better understanding, participation, communication, knowledge sharing, and collaboration among the different stakeholders. The contribution is two-fold: presentation of a new collaborative design system and the evaluation of its use in a real-life design context, which demonstrate how these new technology-based workshops may facilitate design management.
