Abstract
Purpose
The purpose of this paper is to present a detailed case study on the methods and organisational structure used for controlling the time schedule for a large and complex project. The paper discusses the use of “project controlling”, a term used to describe project control by a third-party organisation.
Design/methodology/approach
The researchers used action research to collect data for the case study. A member of the research team was a “participant-observer” on the project on a day-to-day basis for a period of 18 months collecting and analysing data which were subsequently analysed by a mixed methods approach.
Findings
The use of a “Project Controlling Unit” operated by an independent adviser organisation has significant advantages over traditional methods. It can provide timely, consolidated, independent guidance to the client and assistance to other participating organisations.
Research limitations/implications
The research has confirmed the effectiveness of the method on the project under study.
Practical implications
The findings provide guidance for enhanced project control on large complex infrastructural projects that will be of interest to other researchers, other clients and other construction organisations both within China and internationally.
Social implications
Organisations that seek to develop Project Controlling Units to implement the methods described in this paper will need to review their recruitment and training strategies to ensure that appropriate and experienced staffs are engaged.
Originality/value
The paper extends the knowledge relating to “project controlling” method. The findings provide additional insights to progress reporting and the management of construction production on HOPSCA and other large infrastructural projects.

Abstract
Purpose
The purpose of this paper is to understand the philosophical changes which underpin research and practices in project management. This study is an attempt to challenge previous studies that have tried to explain this change in order to provide a better explanation.
Design/methodology/approach
The authors adopt a critical review research method to challenge previous explanations of the paradigm change and definition of communication. For this purpose, philosophical and social theories and concepts have been used.
Findings
This paper proposed changing the paradigm from modernism to postmodernism and the paradigm shift, which happens from postmodernism to participation, as a better explanation for the paradigmatic change in project management. Furthermore, the important role of communication has been illustrated in the participation paradigm.
Originality/value
For the first time in project management, the authors attempt to clarify the role of power in this paradigmatic shift, especially because this concept is an axial concept in postmodern philosophy and a neglected concept in project management literature. In addition, communicative action theory has been used with the aim of pursuing the influence of informal power in the participation paradigm and paving the way for confronting its emerging challenges in future studies.

Abstract
Purpose
This study aims to develop a novel theoretical model for predicting the users’ intention to use virtual tools designed for construction risk evaluation. Risk evaluation is a vital objective for construction managers. This paper intends to examine critical factors such as potential benefits, motivation, performance expectancy and rich sources of information that may affect users’ intention to use virtual technology.
Design/methodology/approach
A pile training module (PTM) was developed in a virtual environment to analyze the proposed virtual reality-technology acceptance model (VR-TAM) factors. Further, a questionnaire survey was conducted with the participation of 102 construction professionals in China to validate the proposed VR-TAM model and PTM tool. The retrieved data was computed to test the proposed model by using partial least squares structural equation modeling and the significance of the PTM tool in a virtual environment.
Findings
The results of this study reveal that high-significance paths represent five relationships between crucial factors affecting users’ intention to use a selected virtual reality (VR) module. Five of seven hypothesis paths were significant with acceptable t-values. By quantitative measurement of high-significance paths, this research has found that each factor under VR-TAM has received significant loadings, with many above the 0.7 threshold mark and others around 0.6. The top factors include “motivation” and “benefits” and have multiplier effects on “intention to use” as the source factors.
Practical implications
The finding of this study presents crucial factors for VR adoption, and the proposed VR-TAM model contributes to the body of knowledge toward managing construction risk using pre-optimization and understanding in a virtual environment. This study supports Chinese construction company managers in effectively using VR technology in their construction projects for risk assessment and management.
Originality/value
This study offered the development of a novel VR-TAM integrated with risk assessment techniques for piling processes. Further, the developed model was analyzed by using a survey of Chinese construction professionals to collect perceptions about the modified theoretical model of VR-TAM.

Abstract
Purpose
Contractor selection is critical in green buildings (GBs) since the preferred contractor has the responsibility to achieve construction sustainability as well as relationship sustainability. The developer satisfaction reflecting requirements can boost the cooperative relationship among stakeholders and act as an evaluation scale for the success of GB projects, which needs to be emphasized in the selection process but little involved in the existing research. This study explores improving GB contractor (GBC) selection by integrating developer satisfaction into selection procedures.
Design/methodology/approach
A systematic framework of GBC selection including twenty-five criteria from literature review and experts survey is firstly constructed. Both tactical and strategic criteria are further classified into Kano categories (must-be, one-dimensional, and attractive categories) using the fuzzy Kano model (FKM), and weighted by the developer satisfaction index. The model proposed by this study combining FKM and TOPSIS divides the selection process into the filtration phase and selection phase by Kano categories. The proposed model is finally verified through performance comparison among multiple methods in a case.
Findings
Selection criteria are measured linearly and nonlinearly, showing criteria having nonlinear satisfaction change accounts for two-thirds of all. Criteria at tactical level tend to be must-be or one-dimensional categories for the developer, and most strategic criteria are classed as the attractive category, indicating that adding strategic criteria is necessary for long-term cooperation. The proposed model, using developer satisfaction to improve the selection process, ensures the selected GBC to be the most satisfactory with requirements of the developer and makes the performance of GBCs easily distinguishable.
Originality/value
This study contributes to the existing body of knowledge for promoting relationship sustainability by supplementing an integrated model with emphasis on developer satisfaction in GBC selection, so as to establish a good initial foundation due to the match between performances of GBCs and needs of developers. It not only helps maximize developer satisfaction in GBC selection by applying satisfaction to pre-construction management, but also instructs GBCs to prioritize performance improvements. The framework is also conducive for developers to classify selection criteria and select other participants (like green suppliers) from the satisfaction perspective in GBs.

Abstract
Purpose
Off-site construction (OSC) has been regarded as a clean and efficient production approach to help the construction industry towards sustainability. Different levels of OSC technologies vary greatly in their implementations and adoptions. Compared to low OSC level technologies have been applied widely, the adoption of high OSC level technologies (HOSCLTs) in practice remains limited. The adoption mechanism for HOSCLTs by firms has not been clear, hindering their promotion. This study aims to explore the mechanism combining subjective and objective adoption for HOSCLTs.
Design/methodology/approach
This study developed an integrated model illustrating mechanism for HOSCLTs adoption based on the technology acceptance model (TAM), which has strong capacity to explain potential adopters' subjective intentions to adoption, and the task-technology fit (TTF) theory, which well describes the linkages between the task, technology and performance in technology adoption. The proposed model was then empirically evaluated through a survey of 232 practitioners in the Chinese OSC industry using partial least squares structural equation modeling.
Findings
The results indicate that both task characteristics (TAC) and technology characteristics (TEC) positively affect TTF of HOSCLTs. TAC, TTF, firm conditions and stakeholder influence have significant positive effects on perceived usefulness (PU), which further positively influence attitude towards adoption. TEC and firm conditions are significantly related to perceived ease of use (PEU). TTF, PEU and attitude towards adoption are good predictors of behavior intention to HOSCLTs adoption. PEU only significantly influences adoption intention and is not observed to influence attitudes and PU, unlike prior research on common OSC adoption.
Originality/value
This study contributes to the body of knowledge by exploring HOSCLTs adoption in the industry based on distinguishing the levels of OSC technologies and supplementing an integrated model for explaining the mechanism with the combination of subjective and objective adoption. The study also provides useful insights into understanding and promoting HOSCLTs adoption for policy makers and stakeholders actively involved in the OSC field.

Abstract
Purpose
There is growing recognition that effective project control systems (PCS) are critical to the success of projects. The relationship between the individual elements of PCS and successfully achieving project objectives has yet to be explored. This research investigates the enablers and barriers that influence the elements of PCS success and drive project objectives.
Design/methodology/approach
This study adopts a mixed approach of descriptive analysis and regression models to explore the impact of six PCS elements on project outcomes. Petroleum and chemical projects in Saudi Arabia were selected as a case study to validate the research model.
Findings
Data from a survey of 400 project managers in Saudi’s petroleum and chemical industry reveal that successful PCS are the key to achieving all project outcomes, but they are particularly critical for meeting project cost objectives. Project Governance was identified as the most important of the six PCS elements for meeting project objectives. A lack of standard processes emerged as the most significant barrier to achieving effective project governance, while having skilled and experienced project team members was the most significant enabler for implementing earned value.
Practical implications
The study offers a direction for implementing and developing PCS as a strategic tool and focuses on the PCS elements that can improve project outcomes.
Originality/value
This research contributes to project management knowledge and differs from previous attempts in two ways. Firstly, it investigates the elements of PCS that are critical to achieving project scope, schedule and cost objectives; secondly, enablers and barriers of PCS success are examined to see how they influence each element independently.

This study aims to map out contractors' thoughts on construction-related environmental recovery as an excuse for deliberately carrying on unsustainable construction.
Abstract
Purpose
This study aims to map out contractors' thoughts on construction-related environmental recovery as an excuse for deliberately carrying on unsustainable construction.
Design/methodology/approach
A typical highway construction project in China was investigated. Textual materials were collected through semistructured interviews. Content analysis was conducted to derive qualitative data from the textual materials.
Findings
The research findings reveal a trend of environmental recovery associated with construction activities. It is found that contractors utilize this trend to maintain unsustainable construction. Furthermore, the effects of environmental recovery equip local governments with a tolerance for environmental degradation, and the environmental tolerance allows contractors to continue unsustainable construction without being discovered.
Originality/value
This paper presents an environmental recovery-based perspective on unsustainable construction and sheds some light on the promotion of sustainable construction.

Abstract
Purpose
The purpose of this paper is to study the rent-seeking behavior of stakeholders in construction projects and to provide a reference for further studies on collaboration in China, which could thus improve the collaborative management in construction and reduce the waste of resources.
Design/methodology/approach
In this paper, the authors discuss and analyze the current situation of rent-seeking behavior in infrastructure construction projects, integrated project delivery (IPD), and the application of a building information model (BIM) in China. The authors analyze the collusive behavior between the supervision department and the contractor via the rent-seeking model on the basis of the game theory and present that BIM and IPD have a positive impact on rent-seeking activities of construction projects. The key factors influencing the rent-seeking activities from the perspective of the owner are studied via a questionnaire survey.
Findings
The research status of IPD in China includes the application of IPD, IPD collaborative management and the combination of lean construction (LC), IPD and BIM. The enthusiasm of the adoption of BIM and IPD is higher for design institute, construction units, research institutions and universities. The findings indicate that the owner appears to have a significant influence on stakeholders in construction projects, such as supervising efficiency, rewards and punishment. Therefore, the results also demonstrate that the construction project based on BIM and IPD can effectively avoid the rent-seeking activities of the participants.
Research limitations/implications
The findings are primarily based on questionnaire data originated from Central China; hence there are some limitations that are worth noting.
Practical implications
First, it provides compelling data evidence for the adoption of BIM and IPD in China. Second, it paves a solid foundation for the behavior of stakeholders in construction projects based on BIM and IPD.
Originality/value
In this paper, a game model of contractor, supervisor and owner is established, and a preliminary attempt is made to introduce BIM and IPD into the model for the behavioral research of participants.
