This paper examines the gap between macro-level calls for innovation and the micro-level enactment, by exploring the discrepancies between a public client’s pursuit of innovation and the actions taken at the project level. Through empirical analysis of four infrastructure operation and maintenance projects, we identify discrepancies within and between procurement strategies and project-level practices. Taking a strategy-as-practice perspective, our study shows how procurement strategies are adapted and enacted by inter-organizational project actors, shedding light on why macro-level innovation intent may not translate into expected outcomes at the project level. Our findings underscore the importance of aligning macro-level directives with micro-level actions to drive innovation in construction projects effectively. This research contributes to a better understanding of the dynamics shaping innovation in construction projects, highlighting the critical role of procurement strategies in bridging macro and micro contexts to achieve sustainable development goals.

Despite its declared importance for governing complexity in projects, few empirical studies have studied how different types of supply chain integration (SCI) activities (e.g., coordinative and collaborative integration) interplay and affect performance. To address this gap, the purpose of this paper is to study how complexity can be governed through coordinative and collaborative SCI, and how their interplay affects performance in project-based buyer-supplier relationships. We apply structural equation modeling, using dyadic empirical data from 102 infrastructure projects. The overall results verify our developed model and illuminate how the interplay between contractual and relational governance, in terms of coordinative and collaborative SCI, mediates the effect of technical and organizational complexity on project performance. This study contributes to theory and practice by distinguishing between contractual governance based on formal coordinative SCI and relational governance based on emerged collaborative SCI, as well as showing how their interplay affects performance in project-based supply chains.

Using a proper control system is vital to ensure that project delivery is satisfactory for the client. Prior research has identified relationship history as a potentially vital contingency factor in organizational control, but there is a lack of research on how relationship history affects how different control systems function in project-based contexts. In the Swedish infrastructure market, increased demand has resulted in a need for increased supply capacity. This has spurred new entrants that have no relationship history with the major client, the Swedish Transport Administration. The purpose is therefore to compare how the client’s control systems function in construction projects with familiar (known to the client) and unfamiliar (new to the client) contractors. The case study involves 32 interviews conducted in six infrastructure projects, three with unfamiliar contractors. Findings show that relationship history heavily influences how the control systems function, especially bureaucratic and clan control. The new contractors are unaccustomed with the client’s extensive use of bureaucratic control and perceive it as less suitable in design-build contracts. Furthermore, the lack of relationship history reduces the opportunity to use clan control from the beginning of a project, due to unfamiliarity with both the client and the control system.

Purpose - This paper aims to identify how a public client’s use of control systems (process, output and social control) affect innovation possibilities in construction projects.

Design/methodology/approach - Semi-structured interviews about six infrastructure projects were conducted to identify respondents’ views on innovation possibilities. These possibilities were then analyzed from an organizational control perspective within principal–agent relationships between the Swedish Transport Administration (STA) and their contractors.

Findings - How the client uses control systems affects innovation possibilities. Relying on process control could negatively affect innovation opportunities, whereas output control could have a positive influence. In addition, social control seems to have a weak effect, as the STA appears not to use social control to facilitate joint innovation. Public clients must comply with the Public Procurement Act and, therefore, retain the requirements specified in the tendering documents. Much of the steering of the execution is connected to the ex ante phase (before signing the contract), which affects innovation possibilities in the design and execution phases for the contractor.

Research limitations/implications

This study was conducted with only one client, thus limiting its generalizability. However, the findings provide an important stepping stone to further investigation into balancing control systems and creating innovation possibilities in a principal–agent relationship.

Originality/value - Although public procurement has increasingly been emphasized as a major potential source of innovation, studying how a public client’s use of organizational control systems affects innovation possibilities in the construction sector has received scant attention.

Innovation is often seen as essential for long-term development in the construction industry, but its actual outcomes and processes in construction projects require more attention. Many studies on procurement strategies and delivery systems have focussed on the public transport infrastructure sector, whereas most construction innovation scholars have addressed the innovation phenomenon in construction generally. Thus, the purpose of this study is to compare how two delivery systems, design-build (DB) and design-build-maintenance (DBM), influence project-level innovation. Findings are based on empirical data from a multiple case study of six infrastructure projects, three with DB contracts and three with DBM contracts, in which 12 innovations are identified, described, and compared. The findings show that various kinds of innovations in terms of outcomes and processes are implemented in infrastructure projects, and that the delivery system do effect both dimensions. Long maintenance responsibilities tend to spur contractors to engage in early exploration of sustainable solutions that could be of long-term benefit. The research contributes to procurement literature by exemplifying how delivery systems influence both the outcomes and processes of project-level innovations. It also increases our knowledge about construction innovation as a multi-dimensional phenomenon.

Purpose – To explore the interdependencies between temporary and permanent aspects of project organizing and how they affect the management of public infrastructure operation and maintenance (O&M) activities.

Design/methodology/approach – The paper applies a case study approach and uses Lundin and Söderholm’s (1995) framework of the temporary organization (with the themes of time, task, team, and transition) to distinguish between temporary and permanent aspects of organizing two infrastructure O&M projects.

Findings – This paper adds to the literature on temporary organizations by recognizing a mixture of temporary and permanent aspects of project organizing in an empirical project-level example. In line with previous research, the themes of time, task, team, and transition were shown to be interdependent. Furthermore, the paper broadens the theory of temporary organizations by presenting a project organization with significant permanent aspects.

Practical implications – Project managers of public sector projects need to be aware of the possible mixture of temporary and permanent aspects of project organizing. Management of projects that are found to have a mixture of temporary and permanent aspects should combine the perspectives and management practices of both temporary and permanent organizing. Not acknowledging permanent aspects could lead to management that is not adapted to the prerequisites of project organizing in this context.

Originality/value – The findings further develop the literature on temporary organizations by recognizing that there is not only a mixture of temporary and permanent aspects between the temporary organization and its permanent environment, but there is also a mixture of temporary and permanent aspects of organizing within project organizations.

The need to consider sustainability has substantially increased the complexity of implementing construction and infrastructure projects and new management practices have emerged during the past decade to tackle the global sustainability challenges, where the engagement and coordination of broader competences from stakeholders throughout the supply chain is required. This new project management paradigm has been accompanied by greater attention to the concept of collaborative business arrangements, often called partnering, that has emerged in construction and infrastructure projects to improve project deliveries. However, there are uncertainties about the optimal strategy to foster, integrate and maintain the required collaboration, particularly in sustainable management practices in infrastructure maintenance projects. This paper addresses these uncertainties, based on a single case study of an infrastructure maintenance contract involving an extensive collaborative business arrangement. The findings reveal that different collaborative practices affect diverse aspects of sustainable project management. Further, the extensive collaborative business arrangement has promoted sustainable deliveries based upon organizational learning and continuous improvements. Thus, this study offers an encouraging example of how extensive collaboration can be fostered and play a key role in sustainable project management practices.

With the announcement to tender a project, several strategic decisions are made that have significant impact on the innovation and efficiency potential of a project. The purpose of this study is to investigate and compare how different types of integrative and collaborative procurement strategies may enhance the opportunities for improved efficiency and innovation in infrastructure projects. Hence, it contributes to the scientific debate on buyer-supplier relationships in relation to project performance. Furthermore, it guides public client organizations in steering explicitly for integration and innovation in their projects. Interview-based case studies of ten public infrastructure projects procured based on four different types of collaborative procurement strategies in Sweden and the Netherlands were conducted. The findings indicate that the duration of the collaboration is fundamental in setting the limits for innovation, and that early involvement as well as long-term commitments in maintenance open up for more innovation. Naturally, the potential for increased efficiency is higher than for innovation, and also occurs in collaborations with limited duration. The findings confirm the importance of a learning perspective on procurement strategies for public client organizations and show the importance of explicit considerations on incentives and project governance issues in the front-end phase of a project.

Mitigating emissions of carbon dioxide and other greenhouse gases is critical if we are to meet the increasing threats posed by global warming. Previous studies have shown conclusively that a substantial part of all carbon dioxide emissions comes from transportation, and that Eco-Driving principles based upon strategic, tactical, and operational decisions have the potential to reduce these emissions. However, these well-established principles have been neglected within the construction industry despite the large number of transport-related activities that attend most construction projects. This paper therefore aims to increase awareness and understanding within the industry of the potential reductions of both carbon dioxide emissions and the costs of earthmoving activities that could be achieved through the use of Eco-Driving principles. A new concept labeled ‘Eco-Hauling’, which extends the Eco-Driving concept to earthmoving, is proposed. A case study of a road project has been conducted and used to demonstrate the new concept. Discrete-event simulation is used to support the data analysis as it enables modeling of the dynamic interactions between equipment and activities of multiple different construction scenarios. The presented findings show that a combination of decisions taken from the proposed Eco-Hauling concept can enable earthmoving contractors to substantially reduce carbon dioxide emissions and costs while maintaining productivity. This study has implications for the general advancement of Eco-Driving theory, as well as for project management as it sets out a viable approach for reducing greenhouse gas emissions in construction projects.
