Abstract [en]

There are increasing concerns over building code, regulation compliance, and quality assurance issues in adopting off-site construction techniques in the construction industry related to meeting client expectations and regulatory requirements. Performance-based building regulations often allow for space for innovation but not a safe space for those who intend to introduce new construction techniques not prescribed in building regulations. Through a series of surveys conducted in Sweden, Switzerland, the UK, China, Singapore, and Australia, this study identified approaches and practices used in these countries that overcome compliance challenges when off-site construction techniques are used. The findings showed that manufacturer self-certification is the predominant approach for meeting code compliance requirements. A fit-for-purpose regulatory compliance system also warrants fair allocation of risks and liabilities to anyone involved in the supply chain. However, a healthy and functional regulatory system for off-site compliance requires third-party certification for products and factories and traceability. It is hoped that the lessons learned from this study can help policymakers introduce changes in product standards and legislation in order to improve the compliance and performance of off-site construction. This study concluded that a chain of custody approach is necessary in order to address quality concerns surrounding the adoption of prefabrication technology in countries that are increasingly exploring greater use of manufacturing in construction.

Abstract [en]

Digital transformation (DT) is expected to contribute to the construction industry's ability to meet climate and sustainable challenges and increase companies' productivity. This study aims to explore requirements for, and factors affecting DT in the construction industry. This research goes beyond the technology perspective and focus on factors needed to transform the potential of digitalisation to benefits for organisations in the construction industry. A structured literature review is performed where knowledge gaps are identified, and a framework is developed that maps the required changes, as well as the associated challenges, constraints, and implications.The construction industry & PRIME;s business-to-business logic, and the fragmented and project-based structure is found to have impact on the industry & PRIME;s development within DT. Mainly regarding the DT aspects disruption, structural changes, organisational barriers, and the central aspect value creation. The understanding of DT by scholars and practitioners in the construction industry is found immature and this calls for further research. The research contributes to understanding of the concept DT and proposes, based on earlier DT literature, an adjusted framework for DT in construction, and points out key areas where research in construction has gaps to fill.

Abstract [en]

Purpose: The purpose of this paper is to understand if and how industrialized house building (IHB) could support productivity developments for housebuilding on project and industry levels. The take is that fragmentation of construction is one explanation for the lack of productivity growth, and that IHB could be an integrating method of overcoming horizontal and vertical fragmentation.

Design/methodology/approach: Singe-factor productivity measures are calculated based on data reported by IHB companies and compared to official produced and published research data. The survey covers the years 2013–2020 for IHB companies building multi-storey houses in timber. Generalization is sought through descriptive statistics by contrasting the data samples to the used means to control vertical and horizontal fragmentation formulated as three theoretical propositions.

Findings: According to the results, IHB in timber is on average more productive than conventional housebuilding at the company level, project level, in absolute and in growth terms over the eight-year period. On the company level, the labour productivity was on average 10% higher for IHB compared to general construction and positioned between general construction and general manufacturing. On the project level, IHB displayed an average cost productivity growth of 19% for an employed prefabrication degree of about 45%.

Originality/value: Empirical evidence is presented quantifying so far perceived advantages of IHB. By providing analysis of actual cost and project data derived from IHB companies, the article quantifies previous research that IHB is not only about prefabrication. The observed positive productivity growth in relation to the employed prefabrication degree indicates that off-site production is not a sufficient mean for reaching high productivity and productivity growth. Instead, the capabilities to integrate the operative logic of conventional housebuilding together with logic of IHB platform development and use is a probable explanation of the observed positive productivity growth.

Abstract [en]

Digital technologies as enablers for more sustainable improvements of construction site processes contain interesting opportunities. Little is known how to, in a structured way, assess and implement digital technologies to support development and improvement of construction site operations. Maturity frameworks assess the status quo and guide decision makers to potential improvements. The purpose of this research is to develop a framework for assessing digital maturity of construction site operations. Literature and empirical data were utilized to develop and validate the framework. The framework contains assessment areas that specify the areas of potential improvements, maturity levels that indicate the progression towards maturity, assessment criteria that define organizational aspects of the assessment, and an assessment procedure to guide assessors. The maturity assessment framework contributes potentially to systematization of evaluative processes creating opportunities for a change within processes and organizations enabled by digital initiatives and to long-term improvements on project portfolio level.

Abstract [sv]

Utveckling av digitala tjänster och produkter är en utmaning i pågående byggprojekt, då det finns få färdiga produkter och tjänster på marknaden. Metoder för traditionell byggprojektledning med tydliga ansvarsområden och gränssnitt i form av kontrakt lämpar sig förmodligen mindre bra för utvecklingsprojekt, där vägen är delvis okänd. Byggarbetsplatsens uppfattning är ibland att utvecklingsarbetet av digitala produkter och tjänster är långsam och komplex. Inom mjukvaruutveckling har det utvecklats olika former av agila utvecklingsmetoder för att prioritera mot förändrade behov och genom iterationer röra sig mot slutmålet. En sådan metod, Kanban, har inspirerat tester för agil utveckling inom projektet Digital transformation av byggplatser (DigiTransform). Testerna indikerar att den digitala och agila metoden, som används på distans, skapar möjligheter för snabbare respons och prioritering av byggplatsen. Det kvarstår att undersöka hur metoden mer systematiskt kan användas på byggarbetsplatser.

Abstract [sv]

Kommersiella fastigheter står inför stora utmaningar post Covid-19. Nyttjandegrad av ytor, klimatkrav och resurseffektivitet, samt behovet av att skapa nya kundvärden för att behålla hyresgäster när deras anställda stannar hemma. Datadriven verksamhets- och affärsutveckling för kommersiella fastigheter kan skapa nya kundvärden i byggprocessens sena skeden, men också i fastighetens hela livscykel. Data som skapas och fångas i byggprocessens initiala faser möjliggör nya datadrivna tjänster och affärsmodeller i hela livscykeln och ökar därmed konkurrenskraften. Datadrivna kundvärden operationaliseras genom att använda digitala tvillingar för att utveckla intäktsmodeller och processer genom att samla, bearbeta, lagra och dela data i öppna plattformar.

Abstract [sv]

Utveckling av produktionsnära digitala tjänster uppfattas ibland som långsam och komplex. Traditionellt kommer det initialt en IT-expert som försöker förstå användarkrav. Därefter försvinner experten och för att komma tillbaka efter en tid med en testbar digital tjänst. I detta läge inser ofta byggplatsen att behoven inte fångats upp helt eller att omvärlden har förändrats. Experten har kanske inte förstått verksamhetsnyttan eller gjort fel prioriteringar. Det kan då uppstå en konflikt mellan byggplatsen som inte upplever att man fått det man efterfrågade och nu innebär en ändring en ökad kostnad. Experten uppfattar som att byggprojektet inte vill stå för de förändringar som man efterfrågar och därefter försöker experten minimera utvecklingskostnader genom att kompromissa funktionalitet för att uppnå kundens behov. Detta skapar ytterligare distans mellan experten och byggarbetsplatsen. Inom mjukvaruutveckling finns olika former av agila utvecklingsmetoder med syftet att just för att minimera dessa konflikter och snabba på processen och därmed öka kundvärdet. En sådan metod, DevOps, har inspirerat tester för agil tjänsteutveckling för byggplatser. Testerna indikerar att metoden skapar möjligheter för snabbare respons. Dock kvarstår att undersöka hur metoden mer systematiskt kan användas inom entreprenadföretag på byggplatser i form av vilka organisatoriska förändringar som behövs och hur individer ska utbildas.

Abstract [en]

Purpose – To further the understanding of industrialised house building (IHB) from a temporal, emergentcorporate-ability perspective, this study aims to trace the build-up of corporate assets in an IHB company overtime. The research draws on dynamic capabilities, acknowledging not only what assets the company havedeveloped and currently are exploiting, but also how these assets were develop and managed (i.e. enhanced,combined, protected and potentially reconfigured) to sustain long-term competitiveness.

Design/methodology/approach – A case study design was used to form a narrative that covers theevolution of an IHB company over a 25-year period. Corporate archival material, analysis of original data from alarge number of research studies during 1993-2013 and retrospective reflections of owners and managers,including crosschecking interpretations of archivalmaterial, developed and triangulated the narrative.

Findings – The study presents rich empirical findings on the build-up of corporate assets. Starting from asuccessive process of exploration and exploitation formation of dynamic capabilities eventually played outinto an exponential dynamic capability build-up. The IHB case company displays the ability to not onlycontinuously exploit and renew resources and competences, but also to sense, seize and reconfigurecumulative assets over time. The exponential development of dynamic capabilities resonates to literature onhigher-order dynamic capabilities implying that: the accumulated and higher-order dynamic capabilities aredifficult to imitate and a (any) company must possess higher-order dynamic capabilities to be able to exploitand/or take up IHB.

Originality/value – The study is complementing and potentially challenging frequent framings of the IHBconcept. Previous research has addressed and characterised IHB mainly by encapsulating a moment in timeand, thus, characteristics are momentary and represent static views on IHB. However, IHB has seen a strongdevelopment over the past 25 years, and the study reflects on this development from the perspective of one ofthe IHB-forerunner companies in Sweden. By exploring from a company perspective the developments,reconfiguration and capacity to develop/reconfigure over time in a changing environment, the studyintroduces an alternative understanding of IHB as dynamic capabilities.
