Abstract [en]

The industrialization of wooden house building processes from traditional on-site production to off-site prefabrication is challenging, concerning the possibility of effective handling of numerous product variants, where each house is more or less unique. To obtain high productivity in the production, a well-balanced flow with minimization of waste is of great importance. In Sweden, many off-site house producers are in the starting phases of introducing advanced automation technologies in their production processes and the need for a more detailed process control therefore increases. In previous studies, the installation of windows has been identified as a demanding step in the prefabrication process, since it often creates a bottleneck i.e. the most overloaded part of process (Slack et al., 2016) and thus negatively affects the cycle-time and a balanced production flow.This study aims to understand, how the effectiveness of windows installations could be improved. By using a multiple case-study methodology, processes of several companies are compared and discussed. Further, suggestions for improvements are made for one case company. The results show that a replacement of the windows installation could (a) shorten the cycle-time of one wall by more than 10 %, (b) reduce the queueing time for the entire wall assembly process by more than 48 % and consequently (c) help to create a more balanced production flow.

Abstract [en]

In the past decades, the housing shortage in Sweden accumulated to a level that led to acute problems for many people combined with continuously rising housing prices. The market for single-family houses, where wood dominates with 85 – 90 % of market share, is highly competitive with many companies offering relatively similar products or services. To serve the demand on that market, only 38 % of the existing companies were needed. One way to tackle the existing housing shortage, and to develop new business opportunities, could be to get more companies from the single-family house industry to produce multi-family houses. Current competence in prefabricated house production could be utilised, yet, other areas could act as barriers for these companies. The aim of this study is to identify potential market mobility barriers for Swedish companies currently producing wooden single-family houses to develop towards the construction of multi-family houses. This will be conducted by initial interviews with decision makers in those companies, combined with a survey-study covering companies within the industry. The results show that the main market mobility barriers are related to the strong market presence of traditional building materials, lack of knowledge by the market of wood as a suitable building material and the importance of governmental guidance and actions.

Abstract [en]

Wood buildings are considered as a viable option to support the effort minimizing the current housing shortage in Sweden. Companies trying to develop into this industry are needed to increase the use of prefabricated wooden elements, volumes or modules in an industrialized way. Suitable companies to make this development could be found amongst firms producing wooden single-family houses. These companies currently act on a highly competitive market with many companies offering relatively homogeneous products or services. Therefore, differentiation towards the wooden multi-family house industry could be considered as a long-term strategy, minimizing the economic distress and improving the survival of the company.The study is aiming at describing the development of economic distress and market concentration ratio in the Swedish industry for wooden single-family houses, for an eleven-year period from 2005 to 2015. The companies could be helped to understand, if and how the market concentration ratio and the economic distress are connected, linking company size to economic stability and efficient resource utilization. This will be conducted by applying Altman’s Z’-score model, grouping firms into a risk, a grey or a safe zone, combined with calculating the industry structure by means of the concentration ratio model. The required data were collected from the annual reports of the 51 relevant firms in the industry.

Abstract [en]

Firms in the Swedish industry for wooden single-family houses operate on a highly competitive market. Products are relatively homogenous, easily substitutional and firms mainly compete by prices. Since 2005, the accumulated market share for the five largest firms decreased from 53 % to 39 %, whilst the number of firms in the industry increased by almost 60 %. In addition to these internal issues on industry structure, construction firms are generally sensitive to external impacts, like the current changes in bank loan policy for the customer. Nonetheless, the number of produced single-family houses in Sweden increased by almost 130 % since 2012. Contributing to reducing the existing housing shortage in Sweden, wooden single-family house producers play an important role.

However, earlier studies show that around 40 % of these firms are economically distressed, or in a situation, where they need to take appropriate strategic action to avoid economic distress in the near future. Yet, what actions are appropriate?

This study is aiming at identifying current critical success factors determining economic health of Swedish firms producing wooden single-family houses. By means of these factors, conclusions about appropriate strategic actions might be drawn to avoid economic distress. Data from the 2015 annual reports of 50 relevant firms were collected and processed by means of the Altman’s Z´-score model and regression analysis.

The results show that two factors accumulate to 99 % explanatory power (adj. R2) of financial health: (1) the manufacturing capacity of the firms’ assets and (2) the firms’ equity ratio. These are the current critical success factors for economic health of Swedish firms producing single-family houses. (1) matches todays’ debate about automated prefabrication and (2) can be seen as the way of financing such assets. Thus, these issues should guide the strategic agenda of firms in the industry.

Abstract [en]

Many Swedish firms producing timber-framed houses lack in production development. Their off-site assembly is mainly non-automated and the Swedish building sector was identified to have the highest building costs in the European Union. Production costs account for the majority of these costs, caused by inefficient production processes. In this case study, value stream analysis and expert interviews were performed at a Swedish firm producing timber-framed houses. Focusing on the pre-assembly of window frame modules, possibilities to include the necessary working steps in the main assembly process of the timber-framed walls were identified, in order to eliminate the manufacturing of this component in a separate process. The results show that the average pre-assembly time for a standard window frame module is 29 minutes 52 seconds, excluding all necessary material supply. An analysis of the main wall assembly process revealed an unbalanced process flow and occurring bottlenecks upstream, resulting in queuing time downstream. Here, working steps to directly mount the window into the wall could be included. This would take about five minutes, yet, would not affect the total lead time of the pre-fabricated timber-framed walls but instead free one full-time operator. In total, a more efficient production process could be achieved.

Abstract [en]

Sweden is forecasted to grow its population with 1.1 million people over the next eight-year period, increasing the demand on the construction phase of housing units throughout Sweden. However, at present, 240 of Sweden's 290 municipalities show an existing deficit of available housing units in their regions, resulting in inherent difficulties fulfilling this demand utilizing the current production structure. Therefore, further utilizing wood as a building material could contribute to minimize the gap, as well as fulfilling the EU’s goals towards the Europe 2020 strategy and the EU forest strategies, focusing on development towards innovation, bio-economy, sustainable sourcing and use of raw materials. This study is aiming to identify drivers supporting the Swedish industry of wooden multi-family houses to enable market growth through competitive and sustainable strategies. The representatives within the building process identify drivers, how they perceive their effect on the companies’ abilities to develop based on long-term and short-term strategic impact. Thus, the goal is to find ways in which wooden multi-family houses could compete as a building solution, compared to established solutions, thereby increasing the market share in Sweden. The methods used in this study is surveys distributed to representatives from municipalities, developers, contractors, architects and real estate companies.The result identifies three change drivers influencing the industry development for wooden multi-family houses in Sweden: technological-, knowledge- and environmental- drivers. These drivers have an effect on the companies’ ability for successful new product development and for development of sustainable strategies towards market growth for wooden multi-family houses.

Abstract [en]

The housing industry for multi-family houses in Sweden predominantly uses concrete as a building material, whereas wood only constitutes 8 – 10 % of the market. The strong market position is derived from a historic ban building houses with more than two floors out of wood in Sweden, which was lifted 1994. Thus, it is a barrier the producers of wooden multi-family houses need to overcome by investments in e.g. production technology, product development and operational efficiency. The decisions regarding investment strategies have varying impact dependent on the actors within the building process i.e. municipalities, developers, contractors, architects and real estate companies have different priorities. The aim of this paper is to investigate the factors effecting investment decision as perceived by the different actors in the building process. Thereby, find ways in which producers of wooden multi-family houses can overcome current market barriers by understanding the investment drivers for those actors involved in the building process. The result will highlight investment drivers as perceived by the actors within the building process and if there are drivers that are perceived as unified by all actors, equally if there are specific investment drivers for certain actors with the building process.

Abstract [en]

Industrialization of house building has shifted the activities traditionally done at building site to the off-site assembly. The design, manufacturing processes and on-site assembly in industrialized house building are defined and documented to form a process platform, but these must be evaluated and improved to constantly develop better and more efficient practice. Lean production and philosophy are still not well understood concepts at the shop floor and wasteful activities that decrease production efficiency are often overseen. Current waste categorizations and descriptions seem not to be addressing problem areas and occurrence of waste in prefabrication of single family timber houses. The research aim is to define problem areas that occur during the prefabrication of wall modules, associate them to eight types of waste and identify key problem areas for possible development and improvement. The study was based on secondary data from five case studies that primarily focused on identifying and proposing possibilities for development of productivity. Four problem areas were identified and the future improvement efforts for the prefabrication of single family houses can be placed on developing the processes of the assembly system problem area. The possible future study can aim at quantifying these problem areas.

Abstract [sv]

Användandet av materialet trä i produkter är ett lån från naturen som förr eller senare genom nedbrytning av vedsubstansen ska återföras till det naturliga kretsloppet. Avseende användningen av solitt trä i produkter bestäms tidsperioden innan återföringen till naturen av produktens konstruktion och trämaterialet i sig självt i relation till den omgivande miljön samt användningen och hanteringen av produkten. En produkts förmåga att motstå, eller behålla sina egenskaper trots dessa yttre påfrestningar benämns dess beständighet.
