Public Private Partnerships (PPPs) cover a range of possible relationships between public and private parties. PPP contracts are typically used in contexts great uncertainty, such as large construction infrastructure projects that realized over longer period time. Hence, major challenge PPPs is to keep progress cost-efficient on schedule, under continuously changing circumstances. One way achieve this through clever contracting, by proactively anticipating potential change the planning phase...

Still, projects in the construction sector are delivered with time delays and cost overruns. One of reasons for poor performance was assigned to project complexity. A combination lean agile management hypothesized as a possible solution cope In this paper we aim understand if implicit usage help coping The research done by means correlation analysis on data gathered from structured questionnaire (67 responses). total, 51 significant correlations among 255 relations were found. To reduce...

Research on explorative learning has primarily focused the organizational level. Not much research been done at megaproject level, which is a more complex form of organizing. Therefore, it advisable to analyze how pursuit enabled This draws upon case study Hong Kong-Zhuhai-Macao Bridge (HZMB)—a cross-sea link construction project—to was achieved and sustained. The findings from archival documents, interviews, focus group discussions indicate that megaprojects are likely increase in...

Purpose The authors argue that public project managers do not consider the iron triangle (cost, quality and schedule) primary important in measuring success of their projects. To investigate which criteria are to managers, interviewed 26 Dutch who employed by government responsible for managing infrastructural paper aims discuss these issues. Design/methodology/approach In this research Q-methodology is applied. helps find correlations between subjects across a sample variables. Q-factor...

Recent literature has recognized the difficulty of implementing Circular Economy (CE) in supply chains. This not yet led to a clear understanding reasons. is critical address, because stalls CE transition and suspends its benefits. Therefore, this paper investigates reasons for In so doing Dutch stony materials chain used as empirical case. Through review, role changes responsibilities implementations inside chain, been gained. Based on these insights, Social Network Analysis approach...

The literature on risk management acknowledges a growing number of Risk Maturity Models (RMM). However, for the construction sector, there is no validated RMM that based both theory and experts' opinions. In this article, Generic (GRMM), inspired by EFQM model, developed to remedy shortcoming. GRMM uses list statements extracted from means qualitative content analysis. model are two focus group sessions, which improved. According experts, easy use provides projects with clear picture...

Along with unprecedented urbanization in the last few decades, cities have experienced rapid social and economic transformation China. A major challenge facing urban authorities immediate future is how to plan govern such that they can serve as inclusive systems where everyone enabled empowered fully participate contribute socioeconomic life. first step towards realizing this conceptualize an integrated framework allows analysts decision-makers delineate, evaluate, guide development of these...

Although sustainability is on the agenda of many countries and agencies, it still a great challenge to properly integrate into major infrastructure projects, like tunnels. This remarkable, as commonly accepted that construction operation these civil infrastructures have heavy impact environmental, economic social sustainability. In academia, foregone conclusion seems point lack vision about with respect article presents an empirical study investigates ideas amongst tunnel practitioners in...

In mega projects, the stakeholders may be exposed to significant on-site construction risk, especially owners and insurance companies who take most responsibility for risk loss. It is difficult diversify their risks by undertaking enough similar policies, participating in management has become an important method of active control. Based on principal-agent relationship between owner, company, contractor, this paper establishes incentive mechanisms considering common agency exclusive models....

BIM (building information modeling) can be the basis for carrying out various performance analyses. Sustainable infrastructure rating systems are suitable tools assessing an infrastructure’s environmental performance. It is necessary to integrate them in design process. The research adopted a thorough literature review follow development trends, interviews with professionals from academia and industry, critical analysis of technical requirements integrating sustainability This study...

Current literature shows that poor cost performance in projects has become routine. Research on mostly focused one of the involved parties, either client or contractor. Not many research efforts discuss contingency projects. This discusses and execution phase from perspective a as well Using case study approach, 95 are investigated: 44 51 contractor The results show depending perspective, can have overruns underruns. Comparing total realized estimated costs, experienced average about 16%...

The goal of this study is to identify, classify, explore, and understand decision-making complexity elements in major infrastructure projects (MIPs). This article puts forward systematic definitions decision making, quality, complexity. Based on literature reviews an in-depth case analysis Hong Kong-Zhuhai-Macao Bridge (HZMB), a comprehensive framework developed, which divides the into six dimensions: technical, social, financial, legal, organizational, time. links between different...

The current literature discusses the methods to estimate costs and cost contingency. also distinguishes "known unknowns" "unknown contingencies. Little is written, however, about evolvement of total project estimates during preconstruction phase construction projects. Moreover, not many studies are investigating contingencies in real Practice expressed need for getting more insight into development estimated projects phase. This paper, therefore, (and contingency) phases 29 Dutch flood...

Sustainable development and Circular Economy (CE) have drawn massive attention worldwide. Construction practices consume large amounts of materials, resources energy. Sustainability CE could play a big role in reduction efforts. However, the potential influence both concepts on planning construction infrastructures remains unexplored. This paper investigates how professionals involved high-speed railway station project Chinese city Jingmen envision use sustainability for its surrounding...

Increasing complexity of projects is mentioned as one the reasons for project failure—still. This paper presents a comparative research to investigate how was perceived by practitioners in different industry sectors. Five sectors were included: process industry, construction ICT, high‐tech product development, and food processing industry. In total, more than 140 included research, hence providing broad view on Dutch practice. From assessments, it concluded that only element present top...
