Abstract [en]

Purpose – The construction industry has been criticized for not keeping up with other production industries in terms of cost efficiency, innovation, and production methods. The purpose of this paper is to contribute to the knowledge about what hampers efficiency in supplying engineer-to-order (ETO) joinery-products to the construction process. The objective is to identify the main contributors to inefficiency and to define areas for innovation in improving this industry.

Design/methodology/approach – Case studies of the supply chain of a Swedish ETO joinery-products supplier are carried out, and observations, semi-structured interviews, and documents from these cases are analysed from an efficiency improvement perspective.

Findings – From a lean thinking and information modelling perspective, longer-term procurement relations and efficient communication of information are the main areas of innovation for enhancing the efficiency of supplying ETO joinery-products. It seems to be possible to make improvements in planning and coordination, assembly information, and spatial measuring through information modelling and spatial scanning technology. This is likely to result in an increased level of prefabrication, decreased assembly time, and increased predictability of on-site work.

Originality/value – The role of supplying ETO joinery-products is a novel research area in construction. There is a need to develop each segment of the manufacturing industry supplying construction and this paper contributes to the collective knowledge in this area. The focus is on the possibilities for innovation in the ETO joinery-products industry and on its improved integration in the construction industry value chain in general.

Abstract [en]

Multiple studies have raised concerns about the construction area and issues such as low quality, high costs, low profitability and lack of innovations. Major parts of the processes are project based and characterised by one-of-a-kind setups in which the unique characteristics come from production setup, site, and temporary organisations. The process is characterised by multiple process steps including multiple actors in different parts of the process in a system that has poor information systems in comparison to what is shown by known efficiency theories. The one-of-a-kind nature of projects, site production, temporary multiorganisations injecting new members in the interaction chain, and regulatory intervention are known peculiarities of construction. Problems caused by these peculiarities are lack of feedback cycles, flow configuration difficulties, variability problems, problems in communication of knowledge across organizational boundaries as well as lack of accumulation of improvement in processes. The objective of this thesis was to identify patterns regarding interaction between companies in the construction industry and the sub-suppliers of joinery products. A second objective was to find factors hampering efficiency and cooperation and give some tentative proposals for how to improve communication and cooperation effectiveness. The study shows that the construction related wood industry is mainly orientated towards the traditional construction process, meaning that the organisations are mainly reactive and delimited islands in the value chain. The main visible pattern is that the traditional construction culture means variation and ad-hoc handling in the process. The factors found that hampers efficiency development is lack of cooperation, lack of standardisation, information deficiencies and poor design- and product-quality. The tentative suggestion for the construction industry to be able to come to terms with some of the criticism and problems is to increase the level of industrialisation and cooperation, using efficiency and cooperation philosophies. For a future development in the studied area the tentative suggestion would be to; (1) define the process and the routine actions in the different part processes, (2) define the hand-over points in the value-chain, (3) determine the level of information in the hand-over point in cooperation, (4) increasing the feedback in the system in order to find errors early in the process and (5) increase the general cooperation level preferable with help from external supporters. Added to this a will to change must be introduced in the value-chain, the incitements for change probably must come from society acting, not just criticising.

Abstract [sv]

En mängd studier har uttryckt oro kring byggområdet och frågor såsom låg kvalitet, höga kostnader, låg lönsamhet och brist på innovationer tas ofta upp. Stora delar av byggprocessen är arrangerad i projektform och kännetecknas av enstycksproduktion. De unika egenskaperna i byggprocessen kommer från produktionsorganisation, plats och temporära organisationer. Processen kännetecknas av att den indelas i flera processteg där olika aktörer är aktiva i olika steg. Byggproduktionen som sker i olika processteg har en bristande informationsöverföring i jämförelse med vad som framgår av kända effektivitets teorier. Byggproduktion är känd för ett antal egenheter och de som framträder främst är enstyckstillverkning, projektform, på plats produktion och tillfälliga organisationer. De problem som orsakas av de tidigare nämnda egenheterna är brist på återkoppling, bristande flöde, variations- och kommunikationsproblematik samt brist på effektivisering av processer. Syftet med denna avhandling var att identifiera samspelet mellan företag inom byggbranschen och underleverantörer av snickeriprodukter, samt hitta faktorer som hämmar effektivitet och samarbete och ge tentativa förslag på hur branschen kan förbättra; sin effektivitet, sin kommunikation och sitt samarbete. Studien visar att byggrelaterad träindustri i huvudsak är inriktad mot den traditionella byggprocessen, vilket betyder att organisationerna i huvudsak är reaktiva och kan uppfattas som öar i värdekedjan. Det mest framträdande mönstret för byggrelaterad träindustri är att den är starkt anpassad till den traditionella byggkulturen. Den här anpassningen innebär att en betydande del variation måste hanteras ad-hoc i processen för att uppnå ett fullgott resultat. De faktorer som främst hämmar effektivitet och utveckling är bristande samarbete, brist på standardisering, bristande information och bristande design (inpassnings)- och produktkvalitet. Ett förslag till byggbranschen för att kunna komma till rätta med något av den kritik som riktas mot den och de problem man upplever, är att öka industrialiseringen och samarbetet genom att använda rådande effektivitets- och samverkansfilosofier. För en framtida utveckling inom det studerade området är de tentativa förslagen att, (1) definiera processen och de rutinmässiga åtgärder som finns i olika delprocesser, (2) fastställa värdekedjans överlämningspunkter, (3) fastställa den nivå av information som ska finnas i överlämningspunkten, (4) öka återkoppling i systemet för att hitta fel tidigt i processen och (5) höja den allmänna samarbetsnivån företrädesvis med hjälp från externa aktörer. Till detta krävs en vilja förändring och sannolikt måste incitamentet till förändring komma från att samhället agerar starkare, inte bara kritiserar processen i allmänhet.

Abstract [sv]

Denna fallstudie beskriver svagheter i den samverkan som sker i byggprocessen vid upphandling av specialsnickerier. Resultaten visar på att informationen i processen är bristfällig och att dess överföring inte är säkrad. Kompetens att förädla och modellera information behöver utökas. En stor del av tiden tillförs inget värde till produkten vilket försvårar kommunikationen i värdekedjan vilket påverkar produktens kvalité. Mycket av problemen kan undvikas genom ökad interaktion mellan leverantören, föreskrivande arkitekter, och angränsande processer. En ökad grad av standardisering för samverkan och informationsutbyte, samt att minska systemberoende buffertlager för att öka andelen tid för värdeskapande aktiviteter, är andra förbittrare av prestanda i denna process.

Abstract [en]

The Swedish construction market is characterised in a too low endurable housing production at a too high cost level. Forces are raised to increase the production and lowering the production costs without repeating the experienced mistakes from the Million programs of the 1970s. Thus, the construction market in Sweden faces a challenge in building more apartments at a lower price in buildings that are flexible in design and fit into surroundings. The wood manufacturing industry has found that there is a possibility to meet the demands of the market. In the report More Wood in Construction – Foundation for a National Strategy (DS 2004:1 transl.)* there has been found that there is a potential in wood construction of multi storey buildings. The research in wood construction has mainly been done in the field of technology. In the report there is an interest in new business concepts; one of these concepts is strategic networks. A strategic network can bee seen as a tool for excellence, where different competence in the network create the knowledge needed to be an interesting partner in the constructing area. But the production in the This paper examines the questions of what demands a strategic network state on sub contractors in an industrialised wood construction process and how the integration should be managed. The questions deals with the view on cooperation in the surrounding of the strategic network; this cooperation is needed in areas where the network itself does not have the knowledge needed. A case study in an ongoing creation process of a strategic network will be presented. The project has been studied through interviews with leading representatives at different actors involved in the strategic network creation process. The empirical results show that there is not a neglectable degree of cooperation needed between the network and the sub contractor system. The cooperation involves development in the construction system and a close connection to the different businesses in the strategic network. One tentative suggestion is that the strategic network view is that the sub contractor has to be able to add value to the construction system and take part in developing it; I simply regard the sub contractor being a semimember rather than a contractor. This view creates a new situation and a new way of acting both for the sub contractor and the business in the construction area. *Mer trä i byggandet – Underlag för en nationell strategi (DS 2004:1)

Abstract [en]

The Swedish construction industry is characterised by a too low persistent housing production at a too high cost level. Forces are raised to increase the production and lowering the costs without repeating the experiences of the 1960s. Thus, the construction market in Sweden faces a challenge in building more apartments at a lower price in buildings that are flexible in design and fit into surroundings. The wood manufacturing industry has found that there is a possibility to meet the demands of the market. In the report More Wood in Construction - Foundations for a National Strategy (Ds 2004:1), there has been stated that there is a potential in wood construction of multi storey buildings. The research in wood construction has mainly been done in the field of technology. In the report there is an interest in new business concepts; one of these concepts is strategic networks.In this thesis a case of cooperation in purpose to create an industrialized wood construction system is studied. The cooperation process has been studied through participating observation, interviews and documents. Important events, phenomena, patterns and factors in the creation process are described and analysed. The purpose of the study is to contribute to the knowledge of how a strategic network becomes the model for the introduction of a wood construction system that is cost effective, industrialized, flexible, functional and aesthetic. The study shows that the supporter, an external initiator and financier, play a significant role in the development of the strategic network. Another result is that there is difficult to separate the individual from the company in a cooperation process. A third result is that the company must have a certain degree of competence so it can be a contributor to the construction system. A fourth result is that to be able to develop industrialized wood construction systems there is a need to grasp both the entire construction process and the entire construction system. The empirical results indicate that the cooperation process are created and developed in an early phase of a visionary shape, and thereafter develops into a phase of activities, and finally is introduced on to the market. The creation and development process of the strategic network can be parted into ‘dimensions' and ‘levels'. The dimensions can be parted into primary, substantial and conduct preconditions. In these dimensions the significant factors in the cooperation process are discussed in a supporter level, an implementation level, and a process level.For future cooperation projects in the wood construction area the following general recommendations are stated; (1) define the problem or the possibility, (2) analyse the problem or the possibility in profound terms (with focus on structure and strategy), (3) create an operational work organisation with an authoritative group and sub groups, consider early in the process, which sub processes are governing other sub processes, (4) engage an external chairman and an external project manager, (5) create and maintain good relations with supporters early in the process, (6) work for implementation early in the creation process.

Abstract [sv]

Den svenska byggmarknaden karaktäriseras av en alltför låg uthållig bostadsproduktion och en för hög kostnadsnivå. Röster har höjts för att öka produktionen och sänka kostnaderna utan att upprepa misstagen från Miljonprogrammen på 1960-talet. Den svenska byggbranschen står med andra ord inför utmaningen att bygga fler bostäder som är flexibla och estetiska, till en lägre kostnad. Den trämekaniska industrin har funnit att det finns en möjlighet att möta marknadens efterfrågan. I rapporten Mer trä i byggandet - underlag för en nationell strategi (Ds 2004:1) har det framgått att det finns en potential i flervåningsbyggande i trä. Den forskning som genomförts inom området träbyggande har emellertid främst inriktats mot teknik. I rapporten finns ett intresse för nya affärskoncept; en av dessa koncept är strategiska nätverk. Det strategiska nätverket kan ses som ett verktyg där olika kompetenser i nätverket skapar den kunskapsmassa som behövs för att bli en intressant partner i byggbranschen. I föreliggande uppsats studeras ett fall av en samverkansprocess i syfte att skapa ett industrialiserat träbyggsystem. Samverkansprocessen har studerats genom deltagande observation, intervjuer och dokument. Viktiga händelser, fenomen, mönster och faktorer för skapandeprocessen beskrivs och analyseras. Syftet med studien är att bidra med kunskap om hur ett strategiskt nätverk blir modell för introducerandet av ett träbyggsystem som är kostnadseffektivt, industrialiserat, flexibelt, funktionellt och estetiskt. Samverkansprocessen utvecklar nära relationer mellan företagen i det strategiska nätverket. Studien visar att understödjaren (en extern initiativtagare och finansiär) spelar en avgörande roll för utvecklingen i det strategiska nätverket. Ett annat resultat är att det blir svårt att skilja individen från företaget i en samverkansprocess. Ett tredje är att företaget måste ha den grad av kompetens så att det kan bidra till byggsystemet. Ett fjärde resultat är att för att utveckla ett industrialiserat träbyggande krävs ett helhetsgrepp om byggprocessen och byggsystemet. De empiriska resultaten indikerar att samverkansprocessen skapas och utvecklas i en inledande fas av visionärt slag för att sedan övergå i en fas av aktivitet, för att därefter förverkligas på marknaden. Skapande- och utvecklingsprocessen av det strategiska nätverket kan indelas i dimensioner och nivåer. Dimensionerna kan delas in i primära, substantiella och beteendeförutsättningar. Under dessa dimensioner presenteras de framträdande faktorerna för samverkansprocessen i nivåerna understödjar-, genomförande- och processnivå. För framtida samverkansprojekt inom träbyggnadsområdet föreslås följande generella principer; (1) definiera problemet eller möjligheten, (2) analysera problemet eller möjligheten generellt och fördjupat (med inriktning på struktur och strategi), (3) skapa en operationell aktivitetsorganisation med en styrande grupp och arbetsgrupper, och utred tidigt vilken av arbetsgrupperna som är styrande över de andras utveckling, (4) engagera en extern ordförande och en extern projektledare, (5) skapa tidigt och upprätthåll goda relationer med understödjare och (6) arbeta tidigt för att en realisering ska kunna ske.

Abstract [en]

The Swedish construction market is today characterised in a too low endurable housing production at a too high cost level. Forces are raised to increase the production and lowering the production costs without repeating the mistakes from the Million programs of the 1970s. The construction market in Sweden faces a challenge in building more at a lower price in buildings that is flexible in design and fits into the surroundings. This paper examines the factors and instruments that are conclusive for the wood industry to create an industrialised wood constructing actor. A case conducted in an ongoing wood building project in the middle part of Sweden will be presented. The project has been studied through interviews with representatives, in high positions, at the different actors involved in the project. The empirical results show that there are not an unessential degree of factors affecting the creation of an industrialised wood construction actor. The most important factors lie in the area for project organisation, cooperation forms, common terminology and control over resources and activities. One tentative suggestion is that the industrial network should be seen as an instrument for the development and the success in creating an efficient industrialised wood constructing actor.
