Abstract [en]

Managing digital information in construction is commonly described through Building Information Modelling (BIM), which advocates seamless chains of information, increased coordination between different actors and a life-cycle perspective on information management. However, low adoption outside the design phase entails that handling information in production is in many cases manual and paper-based, which increases vulnerability for upstream errors materialising downstream in production. Furthermore, issues with interoperability surround many areas when managing digital information. For industrialised house-builders, the transmitter and receiver of information are in many cases integrated within the same company or based on long-term collaboration. This affects their ability to manage information and utilise design information, which implies that their strategy for digital information management (DIM) might benefit from being addressed differently compared to more traditional BIM-based approaches. In this paper, we describe and discuss an implemented DIM-solution at an industrialised house-builder in order to address the benefits and challenges with DIM when managing information from design to production. The results imply that in order for several different functions within the company to reap benefits, a customised DIM-solution adapted after the company’s specific needs is a well-suited approach forward to avoid sacrificing functionality when utilising design information.

Abstract [en]

Predefinitions in house-building platforms is developed as routines to manage project building information models over to production data by documents and digital drawings. Visualisation of the information flow in the industrialised house-building process is hard to track and information are often presented as islands, seldom described in the flow for the entire process. Interactive visualisation, using game technology, has open up for new applications of data -transformation, -visualization and -simulation of project information which is less studied in the context of industrialised house-building. This paper tries to address this issue via a combination of game engine technology and the predefined industrialised house-building process. The game engine technology allow development for end -user demands and functionality to express and visualise values for the daily planning and execution of processes. In a case study approach the development and analysis of four building projects were studied and chosen to the range of product platform predefinitions. Based on object structure for different views, models and the related metadata were visualised with an immersive virtual environment prototype. The prototype, based on game engine technology, was developed to manage incoming building projects variations that followed house-building platform predefinitions. As a visualising tool of engineering, on-site planning and production process the game engine technology simulates and visualize views on product structures, production information, assembling and operation instructions by interactive functions in the game environment.

Abstract [en]

Industrialized house-builders are moving towards an enhanced production where management of information along the value chain is critical in order to deliver housing projects on time and with the desired quality. Today digital tools and systems are used in both design and production to produce, deliver and instruct actors throughout the phases of aproject. However, the information usually exists in different islands and manual transfers are required tokeep the flow of information between IT-systems and individuals continuous. A key to improving the ability for the members in different stages of a project to work with the same information is to facilitate different views. One of the building blocks for creating bridges between the islands of information is to introduce bills of materials which can be used to organize information for different purposes. Uniting the use of building information modeling (BIM) withbills of materials (BOM) is therefore our focus in this paper. This is done in the context of industrialized house-building and the facets which it brings to the subject. The aim of this paper is to present an early endeavor into a BOM based approach for structuring information from BIM models. A demonstration tool was developed, and together with application in a case project from an industrialized house-builder, the generation of BOMs from BIM data is illustrated and discussed. The findings illustrates that we can apply different structures to the information located in our BIM models and that we can produce a BOM perspective on our products. Also, it is highlighted that we still need further studies to better understand how application of BOMs in the context of industrialized house-building is realized.

Abstract [en]

Industrialized house-builders in Scandinavia, using prefabrication of timber frame modules, have developed platforms to manage design, off-site production and on-site assembly within flow oriented organizations. A whole sales commitment gives time, cost, and quality benefits for house-building companies and also a clear product offer to clients. To meet the contracting and design process within the variety of clients, standardized procurement processes are developed to meet both internal production flow parameters and external demands, from clients and local planning authorities. The study of a flow oriented contracting process shows how industrialized house production parameters and end customer demands could be combined in contracting phase with clients and local planning officers. The study also describes how industrialized house-builders could communicate internally future projects into a flow oriented process by visualizing demand parameters for each project that meet or deviates from platform variables.

Abstract [en]

Some of the requirements governing the design of houses are common between projects. This opens up for using modularization based on product commonalities. Though modularization is well known in the manufacturing industry, its use in house-building contexts is less studied. Even more scarce is research focusing on how requirement commonalities between one-of-a-kind products are found and managed in a modularization process. In this research, modularization from a requirements management perspective is empirically explored using a case study approach. Though the studied modularization process can be described as sequential, the process steps are highly interrelated, with overlaps and iterations. Commonalities are found by functional decomposition of the customer's portfolio projects, tracing technical solutions back to their initial requirements. These are balanced with the customer's requirements on the product and on the design automation tool. The requirement list is continuously updated based on portfolio analysis and communication of modularization results to the customer

Abstract [en]

Several methods exist for design management such as Agile project management, the Last Planner System®, and configuration in diverse variants. Construction can be realized using different degrees of pre-engineering i.e. different production strategies, which can affect the design management method. The research aim is to describe different design management methods and discuss their capacity to function in existing production strategies in construction. Data was collected as secondary data from earlier publications on Agile project management, the Last Planner® system, configuration, and visual planning. Agile project management has a strong focus on customer value and lends itself well to situations with little pre-engineering. The Last Planner System® in design has a strong focus on the co-creation of flow and coordination of actions. In industrialised housing a dialect of Last Planner System® named KI-VP is implemented drawing upon predefinition of design tasks through standardized work. Configuration is the ultimate predefined design stage, where everything can be automated based on product variants.

Abstract [en]

Early planning decisions are usually dependent on time-demanding, manually produced cost estimations and schedules. There is a trend in the construction industry to use 5D-BIM to speed up these processes and automated approaches can be used to further improve effectiveness. This research aims to investigate how to create an automated 5D-BIM planning process when using industrialized building systems. We propose an approach that combines a BIM manual with predefined databases based on the building system and its properties. A case study at one of Scandinavia’s largest construction and property development companies was conducted where the presented approach was tested. The findings show that planning using 5D-BIM is possible to partially automate through our approach but that there are challenges for a fully automated process in the standardization required and assuring that the quality of data in each step is adequate.

Abstract [en]

As the construction industry continues its digital journey the applications within design automation is growing, making development processes less time-demanding and more organized. Design automation applications can show design impact on e.g. cost, equipment availability, staff capabilities and buildability. It can also facilitate reuse of successful solutions instead of reinventing the wheel for every project. Thanks to automation it becomes easier to generate several solutions and trying different what-if-conditions. The field has many different approaches but an overview for construction where the connections between the different approaches are indicated is needed. The purpose of this paper is to describe our view of how the design automation fields of building information modelling, master models,  nowledge-based engineering, configuration, modularization, platforms and simulation are  onnected and to provide input to the design automation discussion in construction. Each of  hese areas are introduced and then they are analyzed in relation to each other and presented as an overview. These results will serve as a base for future studies.

Abstract [en]

An open platform used for industrialised house-building imposes restrictions on the flexibility of the product offering when developing design standardisation. How design process standardisation incorporates variations in products has not been widely studied. The aim of this research is to explain how design breakdown enables Lean Product Development Flow (LPDF) and look-ahead planning in an industrialised house-building context where an open platform is used. A case study was conducted of how one of the leading industrialised house-building companies in Sweden introduced the LPDF tool Knowledge Innovation/Visual Planning (KI-VP) into their design process. The implementation of KI-VP led to an increased cross-functional understanding of relationships between activities, which are an important factor in achieving flexibility and a synchronised workflow. By using design standardisation, look-ahead planning was implemented and used in the management of design flow. Standardisation through design breakdown provides a basis for knowledge innovation that enables improvement of the open platform using a bottom-up approach and increases the production flow.

Abstract [en]

Increasing industrial productivity and innovation is essential to meet needs to reduce lead times and costs. However, diffusion of systemic innovations in project-based industries (PBIs), such as the infrastructure sector, has proven difficult. The Swedish Transport Administration (STA) has unique opportunity to influence the degree of innovation in the sector, due to its strong position as the largest public client of infrastructure in Sweden. Therefore, the aims of an ongoing study reported here are to identify and evaluate challenges and requirements affecting the diffusion of innovation related to this key client. This is being done by examining relevant aspects of construction infrastructure projects executed via the pre-defined design procedure currently applied by STA. The results reveal that the procedure hampers diffusion since certain activities must be performed early, is applied indiscriminately to all types of projects, and hinders inter-organizational collaboration.
