The construction industry is a labor-intensive industry, hence, the presence of labor with high productivity at each stage of the project plays a significant role in achieving project success. The purpose of this paper is to provide real-life empirical data about the current level of construction productivity, in this case electrical installation work, within construction projects in Norway. In addition, it was of interest to identify the areas which have the highest potential for improvement of labor productivity.

This study considers the construction labor productivity through an elaboration on productive vs unproductive time within construction projects. It is based on a “frequency study” done on eight construction projects in Norway. The “work sampling” method has been used for collection of empirical data. For each project, four electricians were observed an entire working day and the amount of time they spent on performing each activity was recorded every 60th seconds. The activities observed were based on a predefined set of activities.

The results of the observations show that on average, 61.1 percent of the time was direct value-added work. This number is significantly better than what is normally discussed as being productive time. However, the findings also show that there is still potential for improvement. The activities that have the highest potential for improvement include “material transfer,” “amendments to already executed installation,” “personal needs” and “waiting times.”

The study results will be of immense benefit to managers of construction projects as well as managers of construction organizations in enhancing their project performance and productivity.

This paper contributes both theoretically and empirically to the current discussion and findings on labor productivity and its relation to project success. The results presented in this paper have important implications of labor productivity in construction projects and future studies in the area of project performance.

Many leisure boat manufacturers have thrived on designing and building highly customized boats based on longstanding traditions of craftsmanship. To achieve efficient value chains, it is not enough to optimize each process step, but also important to achieve a smooth flow through the dependencies between each process steps. The purpose of this paper is to focus on assessing enablers and disablers for operational integration in a craft-oriented small enterprise.

One case company has been studied, to identify enablers and disablers for operational integration in the value chain. The research methodology is based on semi-structured interviews with selected persons from different levels within the company.

The results indicate the importance of management promotion and support of integration and a strong relationship between foremen and operators. Furthermore, to avoid functional myopias, mechanisms to encourage horizontal integration could be useful. Small company and informal culture make integration easier. However, to further establish a common standardized platform, could be necessary. Even small physical barriers in the layout were experienced to affect the integration negatively.

This has been an exploratory study of one single craft-oriented enterprise; hence it is difficult to generalize.

Based on empirical findings from the case study, recommendations on how to achieve better operational integration will be presented.

The research initiative provides knowledge experience of operational integration from a case study in one company within craft and artisan sector in Norway.

The front-end phase plays an important role in achieving project success, and establishment of performance measurement systems considering project challenges or pitfalls is a way of keeping track of this phase. Early warning signs, a type of proactive performance indicators, may serve as means for improving decision-making and project processes aiming for short- and long-term project success. In this paper, the authors present findings from a study on early warning signs (EWS) in hospital projects' front-end. A preliminary systematisation of identified signs as a contribution to front-end improvement is provided.

The paper is based on a mixed methods approach, using a sequential, exploratory research design comprising document studies, interviews and a survey.

The authors identified 62 challenges for hospital projects' front-end performance and further established four categories of EWS as follows: (1) structure and tools, (2) context and frame factors, (3) management and (4) relational factors and properties. This mirrors the presence of hard and soft issues from previous studies. There is need for clarifying terminology and raising consciousness on EWS. Processual approaches to identify EWS are considered more useful than subsequent established indicators.

The findings from this paper provide insight into EWS in hospital projects' front-end phase. This adds to the general understanding of EWS and contributes to more knowledge on the front-end phase in general.

Transaction costs in projects can be reduced through improved collaboration between contractors and clients. The purpose of this paper is to respond to the call for further research on the framework suggested by Li et al. (2015) who presented 26 factors that determine project transaction costs. The objective is to empirically test the framework to identify factors that have the greatest influence on project collaboration so that practitioners can prioritize their efforts on the most salient factors that will improve collaboration and reduce transaction costs.

The paper employed interviews with 38 project practitioners from three different industries in Norway. The respondents had in average 20 years of professional experience.

The quality of communication, project uncertainty, owner’s organizational efficiency, change orders and trust were the five most frequently found factors that influence both project transaction costs and collaboration level. When the authors compared findings between different industries the authors found that the quality of communication was important for all industries. The owner’s organizational efficiency was also highly important in oil and gas and ICT projects. Trust was particularly important in oil and gas projects while frequency of claims was particularly important in construction projects.

This paper identifies the five most important factors for project practitioners to prioritize in order to reduce transaction costs through improved collaboration.

The paper contributes to the conceptual theory of transaction costs and collaboration as it empirically tests and extends the framework developed by Li et al. (2015).

In the project initiation phase, an appraisal is needed to clarify the strategic problem and alternative solutions. Full-scale construction projects and simple solutions (do-minimum alternatives) should be assessed. The do-nothing alternative is the baseline for the appraisal and an option in itself. The paper explores the role of do-nothing and do-minimum alternatives in public project appraisal, which may significantly impact the attractiveness of a construction project.

The paper presents an empirical study from Norway, which requires external quality assurance (QA) of early project appraisals. The data include an extensive document review of 112 projects and interviews with 41 experts involved in the appraisal processes.

Of 112 appraisals, 110 recommended a major construction project, including cases where the benefits and value were low or uncertain. The do-nothing alternative was generally included as a reference but not treated as a viable option. Do-minimum alternatives were often not explored. By contrast, the external QA reports recommended do-nothing or do-minimum in 28 cases. Interestingly, although political decision-makers rarely reject projects, they may put them on hold indefinitely, implying that the actual outcome in many cases is still do-nothing.

The paper addresses a topic that has been understudied in the literature. The findings contribute to the broader literature on project initiation processes, project appraisal and how to reduce the risk of bias and manipulation in appraisals.

The purpose of this paper is to examine people’s understanding and evaluation of uncertainty intervals produced by experts as part of a quality assurance procedure of large public projects.

Three samples of educated participants (employees in a large construction company, students attending courses in project management and judgment and decision making, and judges of district and appeal courts) answered questionnaires about cost estimates of a highway construction project, presented as a probability distribution.

The studies demonstrated additivity neglect of probabilities that are graphically displayed. People’s evaluations of the accuracy of interval estimates revealed a boundary (a “cliff”) effect, with a sharp drop in accuracy ratings for outcomes above an arbitrary maximum. Several common verbal phrases (what “can” happen, is “entirely possible” and “not surprising”) which might seem to indicate expected outcomes were regularly used to describe unlikely values near or at the top of the distribution (an extremity effect).

All judgments concerned a single case and were made by participants who were not stakeholders in this specific project. Further studies should compare judgments aided by a graph with conditions where the graph is changed or absent.

Experts and project managers cannot assume that readers of cost estimates understand a well-defined uncertainty interval as intended. They should also be aware of effects created by describing uncertain estimates in words.

The studies show how inconsistencies in judgment affect the understanding and evaluation of uncertainty intervals by well-informed and educated samples tested in a maximally transparent situation. Readers of cost estimates seem to believe that precise estimates are feasible and yet that costs are usually underestimated.

This paper proposes a progressive, multi-level framework for diagnosing maintenance performance: rapid performance health checks of key performance for different equipment groups and end-to-end process diagnostics to further locate potential performance issues. A question-based performance evaluation approach is introduced to support the selection and derivation of case-specific indicators based on diagnostic aspects.

The case research method is used to develop the proposed framework. The generic parts of the framework are built on existing maintenance performance measurement theories through a literature review. In the case study, empirical maintenance data of 196 emergency shutdown valves (ESDVs) are collected over a two-year period to support the development and validation of the proposed approach.

To improve processes, companies need a separate performance measurement structure. This paper suggests a hierarchical model in four layers (objective, domain, aspect and performance measurement) to facilitate the selection and derivation of indicators, which could potentially reduce management complexity and help prioritize continuous performance improvement. Examples of new indicators are derived from a case study that includes 196 ESDVs at an offshore oil and gas production plant.

Methodological approaches to deriving various performance indicators have rarely been addressed in the maintenance field. The proposed diagnostic framework provides a structured way to identify and locate process performance issues by creating indicators that can bridge generic evaluation aspects and maintenance data. The framework is highly adaptive as data availability functions are used as inputs to generate indicators instead of passively filtering out non-applicable existing indicators.

Scandinavian research in systems development can be grouped into three major traditions, based on quite different ideologies and theories: the systems theoretical school, the socio‐technical school and the critical school. The differences between these schools are closely related to the historical and social contexts in which they developed. External political, economic and cultural factors have strongly influenced research in this field. In particular, the basic theoretical differences between the schools reflect their different interpretations of the relationship between capital and labour.

The purpose of this paper is to present practical difficulties in attempting to implement a partnering approach.

The paper comprises empirical evidence from case studies in Norway and Canada and an extensive literature review on partnering.

The authors identified a lack of shared understanding of key partnering concepts, missing initial effort to establish shared ground rules, communication difficulties in inter‐organizational relationships and unclear (perceived) roles and responsibilities. In existing partnering literature, a large number of construction studies have identified conceptual partnering models. However, studies that describe partnering models to take these practical difficulties into account have not been found and the paper develops a practical model that outlines the phases of a typical partnering effort.

Partnering has both a legal/contractual side and a management/collaboration side. This paper looks at the management and collaboration aspects of partnering only.

The paper will be a very useful source of information and advice for project managers who are attempting to implement partnering in projects.

The paper presents organizational challenges and difficulties in attempting to implement partnering and a practical model which takes these difficulties into account.

The Institute dates back to 1952 when Torben Agersnap started at the Copenhagen School of Economics and Social Sciences. By 1969 it had a staff of three researchers, but in the following years it has grown rapidly. Today the Institute comprises a staff of two full professors, seven associate professors and nine research fellows all on the payroll of the School. In addition there is a staff of about five researchers on various grants and projects.
