Purpose – The purpose of this paper is to characterize the relationships between air pollutant emissions from heavy duty diesel equipment and highway construction project scope, schedule, and budget. Objectives included estimating total project emissions; developing a daily emissions profile; and developing new emissions estimating metrics based on project scope, schedule, and budget. Design/methodology/approach – The research approach involved collecting real-world data related to project scope, schedule, and budget from two highway case study projects. The data were used to establish an emissions inventory estimating methodology to calculate total emissions for each case study. The total emissions were normalized based on project size, duration, and cost in order to develop new emissions estimating metrics. Findings – The results proved that it is possible to characterize total equipment emissions based on project size, duration, and cost. The new emissions estimating metrics were quantitatively similar for both case studies. Research limitations/implications – The results were based on two case study projects. Additional data from more projects is needed to provide more highly refined numerical results. Practical implications – This approach enables project planners and managers to assess the environmental impacts of highway projects along with the financial and time impacts. Social implications – Construction equipment is a major contributor to the nation’s air pollution problem. Before pollutant emissions can be managed they must first be measured. Originality/value – The new emissions estimating metrics are a novel approach to comparing environmental impacts of two or more projects, as well as estimating total emissions for future highway construction projects.

Purpose The effective management of inter-organizational integration is central to complex projects. Such projects pose significant challenges for integration, as organizations struggle with constantly changing inter-organizational interdependencies and must develop and adapt integration mechanisms to meet new demands. The purpose of this paper is to understand what kinds of integration mechanisms are used and how they are developed and adjusted during the infrastructure alliance projects. Design/methodology/approach This study provides empirical evidence of integration dynamics in project alliancing by analyzing two infrastructure alliance projects – a complex tunnel construction project and a railway renovation project. The research approach is an inductive case study. Findings This paper identifies integration mechanisms adopted in two case projects and three central triggers that led to changes in the integration mechanisms: project lifecycle phase, unexpected events and project team’s learning during the project. Practical implications Integration capability should be a precondition for alliance project organizations and requires the adoption of a wide range of integration mechanisms, as well as an ability to adjust those mechanisms in response to everyday dynamics and emergent situations. Originality/value Although unplanned contingencies and the responses to them represent important influences in organizations, there is limited amount of research on the dynamics of integration. The findings will be of value in supporting the management of inter-organizational integration in complex, uncertain and time-critical construction projects.

PurposeThis study aims to develop a framework for optimizing the spatial requirements of the equipment in a construction site using a geographic information system (GIS).Design/methodology/approachAn ongoing construction project, an existing thermal powerplant in India, is considered to be the case study, and the corresponding construction activities were scheduled. The equipment spaces were defined for the scheduled activities in building information modelling (BIM), which was further imported to GIS to define the topology rules, validate and optimize the spatial requirements. The BIM simulates the indoor environment, which includes the actual structure being constructed, and the GIS helps in modelling the outdoor environment, which includes the existing structures, temporary facilitates, topography of the site, etc.; thus, this study incorporates the knowledge of BIM in a geospatial environment to obtain optimized equipment spaces for various activities.FindingsSpace in construction projects is to be considered as a resource as well as a constraint, which is to be modelled and planned according to the requirements. The integration of BIM and GIS for equipment space planning will enable precise identification of the errors in the equipment spaces defined and also result in fewer errors as possible. The integration has also eased the process of assigning the topology rules and validating the same, which otherwise is a tedious process.Originality/valueThe workspace for each activity will include the space of the equipment. But, in most of the previous works of workspace planning, only the labour space is considered, and the conflicts and congestions occurring due to the equipment were neglected. The planning of equipment spaces cannot be done based only on the indoor environment; it has to be carried out by considering the surroundings and topography of the site, which have not been researched extensively despite its importance.

PurposeThe purpose of this study is to explore the best practices for improving risk culture and defining the role of actors in risk governance.Design/methodology/approachThis paper presents an exemplar case of a British insurance company by using a qualitative case research approach.FindingsThe case study shows how the company was successful in changing from a compliance-based and defensive risk culture to a cognitive risk culture by using a systems thinking approach. Cognitive risk culture ensures that everybody understands risks and their own roles in risk governance. The change was accomplished by adding an operational layer between the first and second lines of defense and developing tools to better communicate risks throughout the organization.Practical implicationsPractitioners can potentially improve risk governance by using the company’s approach. The UK regulator’s initiative to improve risk culture can potentially be followed by other regulators.Originality/valueThis is among the few studies that describe actual examples of how a company can improve risk culture using the systems approach and how systems thinking simultaneously resolves several other issues such as poor risk reporting and lack of clarity in roles and responsibilities.

Purpose – Based on the literature devoted to family firms and the intellectual capital-based view of the firm, the purpose of this paper is not only to identify the most important human capital intangibles owned by family firms but also to show a number of indicators that can help measure them. Design/methodology/approach – A qualitative case-study-based research approach was adopted taking as reference: 25 family firms belonging to different sectors; previous works existing in the literature; and the intellectus model. Findings – The present study identifies ten intangibles associated with the human capital of family firms and shows 60 indicators that can be used to measure them. It additionally provides empirical evidence and gives examples of these intangibles through the analysis of 25 international family firms. Research limitations/implications – The difficulty in collecting all the human capital intangibles of family firms; the problems associated with the creation of accurate indicators; and those specific to the research methodology adopted. Practical implications – Identifying the human capital intangibles of family firms and their indicators can help managers become aware of their importance, and this will consequently help them improve their management. This could be an interesting starting point to value these intangibles in the balance sheet as well as to draw comparisons between family and non-family organisations. Originality/value – The framework provided by family firms sheds light on several intangibles specific to these firms – precisely for their condition as “family” firms. Those intangibles – human capital intangibles being especially highlighted in this study – provide the basis for the achievement of competitive advantages.

Purpose The purpose of this paper is to explore, identify and gain insight into factors related to electronic records and information management (e-RIM) issues and their influence on the implementation of e-RIM initiative in military service in Malaysia. This exploration was conducted via a literature review and case study. Design/methodology/approach This study adopted a qualitative approach and used a case study involving two army departments in Malaysia. Interviews triangulated by document content analysis and observations were used for data collection. The data were analysed using a directional content analysis approach. Findings This study reveals that people, organizations, technology and processes are the interrelated contexts underlying e-RIM issues which inevitably influence the implementation of e-RIM initiatives. Competency and leadership, governance structure, culture and strategic planning, technology development and record-keeping process are the main factors impacting such efforts, in turn forming potential obstacles for organizations implementing such initiatives. Research limitations/implications The research approach and design adopted and the sample size were insufficient for generalization of the findings. Practical implications This study shows that e-RIM initiatives pose greater challenges related to various issues that cause difficulties in improving and implementing the initiative. Thus, it is crucial for organizations to ascertain and comprehend the factors that influence e-RIM initiatives prior to formulating strategies and approaches in addressing those factors, which would in turn affect the implementation of e-RIM initiatives. Originality/value This study provides insights into the fundamental factors embracing the e-RIM issues which influence the initiatives, and thereby fosters further discussion and research in the subject matter in Malaysia.

Purpose The purpose of this paper is to link up and think through two bodies of literature, namely the critique of predatory publishing practices and the critique of political economy of established publishers, while introducing a reflection on the dynamic asymmetries of geopolitics and economics of globalizing knowledge production. Design/methodology/approach The authors deploy a conceptual approach developed with reference to a case study in order to explore the embedded logic of the current system of academic publishing. Findings The analysis shows that rather than examining two seemingly different issues (predatory publishing vs established publishers) as conflictual dualism, it is more productive to conceive them in associative and mutually constitutive fashion. Research limitations/implications A nuanced and multidimensional research approach is needed if we are to understand the dynamics of contemporary academic landscape. Originality/value The originality of the contribution lies in its problematizing of three established approaches that feature debates on the transformation of the academy. It moves beyond a micro-level explanation by (the lack of) individual morality as well as a structural explanatory framework preoccupied with publishing infrastructure and culturalist approach based on ready-made dichotomies of west/north vs south/east. Instead, the analysis provides an account that engages both with morality and geopolitics whilst tackling them as dynamic processes in making.

Purpose – Rework is an endemic problem in construction projects and has been identified as being a significant factor contributing cost and schedule overruns. Causal ascription is necessary to obtain knowledge about the underlying nature of rework so that appropriate prevention mechanisms can be put in place. The paper aims to discuss these issues. Design/methodology/approach – Using a supervised questionnaire survey and case-study interviews, data from 112 building and engineering projects about the sources and causes of rework in projects were obtained. A multivariate exploration was conducted to examine the underlying relationships between rework variables. Findings – The analysis revealed that there was a significant difference between rework causes for building and civil engineering projects. The set of associations explored in the analyses will be useful to develop a generic causal model to examine the quantitative impact of rework on project performance so that appropriate prevention strategies can be identified and developed. Research limitations/implications – The limitations include: small data set (112 projects), which include 75 from building and 37 from civil engineering projects. Practical implications – Meaningful insights into the rework occurrences in construction projects will pave pathways for rational mitigation and effective management measures. Originality/value – To date there has been limited empirical research that has sought to determine the causal ascription of rework, particularly in Hong Kong.

Purpose The purpose of this paper is to investigate the social impacts of short-distance office relocation that also involved a new way of working, as perceived by employees during a relocation process. Relocation is any process of moving business premises and can consist of (often) significant change in locality, building change, workplace change and ways of working. This case study was not influenced by the effect of locality change making it hence a short-distance relocation. Design/methodology/approach The social impacts are analysed based on the perceptions of approximately 15 per cent (nine employees) of the case organization across the relocation process – two months before, one week before and four months after the move. The qualitative data collection is conducted by semi-structured interviews, supplemented by diaries and participatory action research. Findings Before the relocation, the subject organization’s old premises were considered inadequate. Still, employees had concerns during the process about the new open office environment including the adoption of new ways of working. Some employees did experience resistance towards the change, although the amount of engagement possibilities was deemed sufficient and engagement recognized as an important part of the process. After the relocation, adaptation was considered easier than originally anticipated and experiences of improved inter-team collaboration were reported by most while others experienced just the opposite, pointing out to emerging individual differences. Research limitations/implications The limitations of this study arise mainly from the ability to statistically generalize on the basis of a single case study which this paper represents. Furthermore, since the last interviews were made four months after the move, all post-occupancy implications were possibly not yet fully experienced. Originality/value The paper provides information on the social impacts of organizational relocation process, as it identifies individual employee perceptions during a relocation process where locality change is minimal. Moreover, the threefold research approach across the relocation process enables the appearance of possible time-dependent development of adaptation to change in employee perceptions and these perceptions to be analysed in more detail.

PurposeThe study aims to find the causes of road projects implementation delays in Blantyre, one of the four city councils (CCs) in Malawi.Design/methodology/approachThe study followed a qualitative research approach using a Blantyre City Council (BCC) as a case study. This study combined in-depth, face-to-face interviews with councillors, secretariat staff, consultants, and contractors who worked on the city's road projects. Data gathered were analysed using thematic content analysis. Also, some road project documents were examined.FindingsThe findings from the case study revealed the primary cause of road project construction delays as the shortage of engineers in conducting detailed proposed projects surveys resulting in incomplete project scope definition before contractor's procurement. Other identified factors were service providers delaying the removal of existing public utility infrastructure from project sites, client funding issues, scope changes, and client delays in issuing instructions to the contractors during project implementation. Another factor was the shortage of construction equipment and construction materials experienced by some appointed contractors.Research limitations/implicationsOnly road construction projects and stakeholders operating from Blantyre city, Malawi, were contacted for the study; thus, the findings may not be generalizable.Practical implicationsThere is an urgent need to increase technical employees, especially engineers and other critical technical staff such as quantity surveyors in Blantyre. Employees' conditions of service should be conducive to attract qualified people to undertake effective management and assessment of projects before commencement to identify the feasibility of proposed projects to decrease the rate of road construction project delays.Originality/valueThe study has established Blantyre city's core challenges in implementing its road projects seamlessly and has provided mitigation measures for dealing with the shortcomings.

Purpose While tourism scholars have increasingly recognized the significance of collaboration as an essential element in tourism development, there is a lack of theoretical and empirical research centering on (trans)local collaboration as a central means for future tourism development in Greenland. The purpose of this paper is to analyze the conceptual and analytic potentials and challenges of collaboration in an explorative case study. Design/methodology/approach The paper applies a case study approach to scrutinize collaboration in the setting of a tourism workshop in South Greenland. This research approach is exploratory in nature and focuses on collaborative activities among participants from different research institutions and countries, from Campus Kujalleq in Qaqortoq, from small-scale enterprises and businesses, managers of destination marketing organizations and local fishermen. Findings Four “collaborative configurations” emerged during the workshop. These inspire and challenge ways of (re)conceptualizing collaborative tourism development in South Greenland and call for the reconsideration of the present approach toward tourism development for shaping new possible future(s) of tourism in the Greenlandic context. Originality/value The relevance of this paper emerges from the crucial significance that tourism actors in Greenland credit collaboration. Moreover, by approaching development issues from within and mutually developing possible practice solutions through collaboration with local tourism actors, the paper aims to give voice to the local community, which currently is lacking in the debate on tourism development in Greenland.
