Abstract

Purpose

Green building is a promising approach to improve resource efficiency and achieving sustainable development. The success of green construction projects is closely associated with the performance of project managers (PMs), while job satisfaction plays a major role in the performance of PMs. However, the emphasis placed on the job satisfaction of PMs in green construction projects remains minimal. The purpose of this paper is to identify the relationships between the job satisfaction of PMs and its key influencing factors in green construction projects, and to propose feasible strategies to improve the job satisfaction of PMs.

Design/methodology/approach

A questionnaire survey is conducted, data collected from 105 construction PMs are analysed using structural equation modelling. Interviews with five industry experts are further conducted to substantiate the results.

Findings

The results identified four major components of job satisfaction, namely, “job content”, “resource adequacy”, “work context” and “the personality and competence of jobholders”. The analysis also found that “technical requirement” and “split incentive” condition of green construction projects, “the expertise and awareness of PMs” and “demand and support from stakeholders” has significant impacts on PMs’ job satisfaction. Furthermore, this study developed eight strategies to improve PMs’ job satisfaction, including “increase recognition opportunities for PMs”, “government incentives and financial support” and “introductory and training courses on green construction legislation and processes”.

Originality/value

The findings assist construction companies in formulating measures to improve the job satisfaction and performance of PMs in green construction projects.

Abstract

Purpose

The purposes of this paper is twofold: first, to assess the risks associated with the international construction joint ventures (ICJVs) between Singapore and developing countries and second, to investigate the risk allocation preferences in these ICJVs.

Design/methodology/approach

A questionnaire survey was conducted and responses were received from 38 firms that had participated in ICJVs with developing countries. A risk criticality (RC) index was adopted to evaluate the criticality of each risk.

Findings

The survey results reported “political instability” as the most critical risk and market-level risks were less critical than country and project-level risks. Additionally, the results showed agreement on the risk ranking between building and infrastructure ICJVs, despite significant differences in the criticalities of five risks. Furthermore, five risks were preferably allocated to host and foreign partners, respectively, while 13 risks could be shared among partners.

Research limitations/implications

First, due to the sample size, one should be cautious when interpreting and generalizing the results. Second, the RC index proposed in this study was subjective as it was influenced by the individual experience and risk attitude of the respondents. Also, the RC values were calculated without considering the weights of the respondents. Lastly, the questionnaire survey, which has been widely used in identifying risk allocation preferences, may not identify the insights of practitioners into the risk allocation practices.

Practical implications

This study provides a clear understanding of the risks associated with forming ICJVs with developing countries and the preferred risk allocation. Although, this study is focused on the risks faced by the Singapore-developing country ICJVs, the identification of the potential risks allows companies from other countries to customize their risk profile and assess the risks before they form ICJVs with developing countries.

Originality/value

As few studies have explored the risk allocation preferences in ICJVs, this study expands the literature and provides practitioners with important information for preparing joint venture contracts or agreements. Thus, this study can contribute to the literature relating to ICJVs.

Abstract

Purpose

Collaborative contracting (CC) is the direction that Singapore is venturing into in line with the Construction Industry Transformation Map. For its successful adoption, it is necessary to examine the potential barriers and possible solutions. Therefore, this study aims to explore the current status, major barriers and best solutions for the adoption of CC in the Singapore construction industry.

Design/methodology/approach

To achieve these objectives, a comprehensive literature review was carried out and 26 barriers, as well as 21 solutions, were identified. Then a questionnaire was designed to assess the priority of these barriers and solutions. After a pilot study, 165 questionnaires were distributed, and 31 responses were received. And the survey result was validated by post-survey with three industry professionals.

Findings

Results revealed that only a small percent of projects adopted CC in Singapore. Seven significant barriers hindering CC implementation were found out. They are “inherent difficulties in changing organizational culture,” “lack of incentives/financial support,” “lack of legislative regulations,” “resistant to change the current way of working,” “seeking for the lowest cost” and “difficulties in converting strategic decisions to operational levels” and “unclear contract terms and objectives.” Also, five best solutions were suggested to overcome the identified barriers.

Originality/value

The findings of this study could enable industry practitioners to be aware of the potential barriers to adopting CC and choose suitable solutions to overcome these barriers. It is also helpful for authorities to come up with effective policies to promote the adoption of CC.

Abstract

Purpose

This paper aims to develop a partner selection approach for the high-speed rail (HSR) firms from the perspective of achieving competitive advantage in the international competitive bidding sphere.

Design/methodology/approach

The current study developed a partner selection approach based on the evolutionary game theory. Firstly, the current study identified the influencing variables and logical formation path of competitive advantage on the international HSR project by literature review and case analysis. After that, a pay-off model was developed based on the theoretical foundation. Meanwhile, the evolutionary stable strategy was analyzed for different combinations of initial pay-offs.

Findings

A real-world case was simulated to verify the effectiveness of the developed approach. The simulation results secured support from three industry professionals, indicating the developed approach is valid.

Originality/value

The current study can help HSR firms to select their partners and develop a cooperation strategy from the perspective of winning awards. Also, the proposed approach is based on the advantage driving variables and formation path, which can contribute to HSR firms' understanding of the sources of competitive advantage.

Abstract

Purpose

Underground logistics system (ULS) is recognized as sustainable alleviator to road-dominated urban logistics infrastructure with various social and environmental benefits. The purpose of this study is to propose effective modeling and optimization method for planning a hub-and-spoke ULS network in urban region.

Design/methodology/approach

Underground freight tunnels and the last-mile ground delivery were organized as a hierarchical network. A mixed-integer programming model (MIP) with minimum system cost was developed. Then a two-phase optimization schema combining Genetic-based fuzzy C-means algorithm (GA-FCM), Depth-first-search FCM (DFS-FCM) algorithm and Dijkstra algorithm (DA), etc. was designed to optimize the location-allocation of ULS facilities and customer clusters. Finally, a real-world simulation was conducted for validation.

Findings

The multistage strategy and hybrid algorithms could efficiently yield hub-and-spoke network configurations at the lowest objective cost. GA-FCM performed better than K-means in customer-node clustering. The combination of DFS-FCM and DA achieved superior network configuration than that of combining K-means and minimum spanning tree technique. The results also provided some management insights: (1) greater scale economies effect in underground freight movement could reduce system budget, (2) changes in transportation cost would not have obvious impact on ULS network layout and (3) over 90% of transportation process in ULS network took place underground, giving remarkable alleviation to road freight traffic.

Research limitations/implications

Demand pairs among customers were not considered due to lacking data. Heterogeneity of facilities capacity parameters was omitted.

Originality/value

This study has used an innovative hybrid optimization technique to address the two-phase network planning of urban ULS. The novel design and solution approaches offer insights for urban ULS development and management.

Abstract

Purpose

Balancing interfirm relationships is important for firms’ long-term superior performance. However, prior studies mainly focus on interfirm competition or interfirm cooperation separately, ignoring the balance of interfirm relationships. To bridge this gap in knowledge, this study aims to develop a framework to evaluate the balance of interfirm competition and interfirm cooperation and propose strategies to optimize a firm’s interfirm relationships.

Design/methodology/approach

After an in-depth literature review, a framework was developed for evaluating and optimizing the interfirm relationships. Taking the high-speed railway industry as an example, the proposed framework was implemented.

Findings

The results of the case confirm that the balancing of interfirm relationships can lead to more superior firm performance. Also, rather than mutual suppression, the interfirm competition and interfirm cooperation present a roughly positive relationship.

Originality/value

This study would contribute to the existing knowledge body by developing a framework for balancing interfirm relationships. Also, this study can aid practitioners in evaluating and optimizing their interfirm relationship structures.

Abstract

Purpose

Facility maintenance is critical for the operation and management of petrochemical plants. Maintenance work completed with higher productivity eventually contributes to better plant performance. Mechanization reduces workforce demand and can increase the productivity of maintenance work. The purpose of this paper is to assess the current mechanization level of the maintenance activities and then identify applicable technology solutions for productivity improvement in petrochemical facility maintenance.

Design/methodology/approach

This paper utilizes a mechanization level assessment method for global maintenance data collection and analysis. Subject matter experts’ interviews and market scanning were used to identify corresponding technology solutions.

Findings

The study discovered numerous maintenance activities with lower mechanization levels and identified more than 50 technology solutions applicable for maintenance productivity improvement.

Originality/value

This paper provides a roadmap for petrochemical maintenance work participants to assess their mechanization level status quo and identify technology solutions for higher maintenance work productivity. The method adopted is replicable and customizable for further applications with different plant conditions in the petrochemical sector and other industrial contexts.

Abstract

Purpose

The purposes of this paper are to: investigate schedule performance of new and retrofitting green building projects; identify the critical factors that influence the schedule performance of new and retrofitting green building projects; and provide solutions to improve schedule performance of new and retrofitting green building projects.

Design/methodology/approach

A questionnaire survey were conducted and responses were received from 34 firms experienced in green building projects in Singapore. After the data from the survey had been analyzed, face-to-face interviews were conducted with two senior project managers to solicit comments on the survey results.

Findings

This study identified the degree of project delay in 98 new green building projects and 51 retrofitting green building projects in Singapore. The result indicated that 22 percent of the Singaporean green building projects were plagued with delay and retrofitting projects had a significantly higher likelihood of delay and significantly longer extension than new projects. In addition, “consultant cooperation to solve problems” was the most influential to schedule performance of both new and retrofitting green building projects, and the two project groups agreed on the overall ranking of the factors affecting schedule performance.

Research limitations/implications

There may be geographical limitation on the conclusions drawn from the findings. Also, the sample size was still small, despite a relatively high response rate. In addition, the majority of the respondents were contractors as other project players were reluctant to respond to the survey.

Practical implications

This study provides a clear understanding of the schedule performance of green building projects as well as the critical factors that should be highlighted when constructing green building projects. Also, strategies to overcome the negative impact of these factors allow practitioners to better deal with the potential causes of delay and to attain the schedule performance.

Originality/value

Although construction delays have been widely investigated in previous studies relating to construction management, few have attempted to analyze the schedule performance of new and retrofitting green buildings. Thus, this study adds significantly to the existing research on both green building and construction delay.

Abstract

Purpose

Rework is a pervasive problem in the construction industry. While several studies have examined the relationship between rework and cost overruns, few have related rework to schedule performance impacts. As a result, the purpose of this paper is to assess rework in the construction industry and its impact on schedule performance. Additionally a discussion of the most probable causes for rework that affect schedule outcomes is presented, with some recommended solutions.

Design/methodology/approach

To achieve the objectives of the study, a questionnaire was developed and the responses from 32 companies in Singapore were analyzed. Furthermore, face-to-face interviews with six industry experts were conducted to get an in-depth understanding of the survey results.

Findings

The findings of this study revealed that rework is a leading factor affecting schedule performance and its occurrence is relatively high in the construction industry, with a significant contribution to construction schedule growth. It also identified certain root causes, namely design-related changes, poor design coordination and poor site management as factors that most negatively affect schedule performance.

Originality/value

It is anticipated that once companies recognize the causes for rework and their impacts on schedule, they will develop strategies to manage and prevent rework, ultimately allowing the industry to improve on project delivery schedule performance.

Abstract

Purpose

The specific purposes of this paper are: to identify the critical drivers for and hindrances to enterprise risk management (ERM) implementation; and to compare the influence of these factors on ERM implementation between large and small-medium (SM) Chinese construction firms (CCFs) in Singapore.

Design/methodology/approach

A questionnaire survey was conducted and responses were received from 35 experienced managers in CCFs operating in Singapore.

Findings

A total of 13 drivers and 22 hindrances were found critical to ERM implementation in Singapore-based CCFs. “Improved decision making” were the top influential driver, while “insufficient resources (e.g. time, money, people, etc.)” were the most significant hindrances. Additionally, despite significant differences in the mean scores of seven drivers and four hindrances, the large and SM CCFs agreed on the rankings of drivers and hindrances, respectively.

Research limitations/implications

As the survey was performed with the Singapore-based CCFs, there may be geographical limitation on the identification of the critical drivers for and hindrances to ERM implementation. The sample size was still small, despite a relatively high response rate.

Practical implications

The findings of this study allow the management to strengthen the positive influence from the drivers and overcome the challenges posed by the significant hindrances.

Originality/value

Despite studies on ERM in various industries, few studies have attempted to disclose the factors driving and hindering ERM implementation in construction firms. Thus, this study expands the existing literature relating to ERM. An understanding of the drivers for ERM implementation enables the management to obtain sufficient support for the ERM program and strengthen the positive influence from the drivers. The identification of the hindrances allows the management to be clear about the challenges faced by the ERM program and take measures to diminish their negative influence and overcome them. Additionally, other construction firms can use the drivers and hindrances identified in this study to prepare their customized list of drivers and hindrances.
