The construction industry plays a significant role to the economy of Hong Kong not only in terms of output but also the employment. The sector, however, has been severely hit by the economic downturn in recent years resulting in serious unemployment. Employment planning becomes one of the critical aspects for the recovery of the economy. The main objective of this paper is to establish a labour demand model for the Hong Kong construction industry. The unique characteristics and the current conditions of the construction labour market are reviewed. Regression analysis based on 123 construction projects was used to compute the relationship between expenditure and site workers employed. The best predictor of average labour demand of construction projects in Hong Kong is found to be DL = 463 C 0.934, where DL is the actual labour demand in man‐days, C is the final cost of contract in millions. The labour demand‐cost relationship can be applied as a manpower forecasting model to estimate the total labour required for a given type of project. The developed model enables a more reliable and accurate planning of manpower requirements in the construction industry.

Rework is an endemic problem in construction projects and has been identified as being a significant factor contributing cost and schedule overruns. Causal ascription is necessary to obtain knowledge about the underlying nature of rework so that appropriate prevention mechanisms can be put in place. The paper aims to discuss these issues.

Using a supervised questionnaire survey and case-study interviews, data from 112 building and engineering projects about the sources and causes of rework in projects were obtained. A multivariate exploration was conducted to examine the underlying relationships between rework variables.

The analysis revealed that there was a significant difference between rework causes for building and civil engineering projects. The set of associations explored in the analyses will be useful to develop a generic causal model to examine the quantitative impact of rework on project performance so that appropriate prevention strategies can be identified and developed.

The limitations include: small data set (112 projects), which include 75 from building and 37 from civil engineering projects.

Meaningful insights into the rework occurrences in construction projects will pave pathways for rational mitigation and effective management measures.

To date there has been limited empirical research that has sought to determine the causal ascription of rework, particularly in Hong Kong.

In an attempt to bring the unique talents of various construction industry project participants together in a more productive and integrated manner, the Online Remote Construction Management (ORCM) project commenced in July 1999 proposing to test, field trial and/or evaluate the implementation of various Internet‐based construction project management (ICPM) systems and information and communication technologies (ICT) on four case study projects over a two‐year period, aiming, in general, to demonstrate leadership in facilitating the use of online technologies for the design, management and construction of building and civil construction projects. This paper provides the final results and a list of “best practice guidelines” that are critical in helping ensure successful implementation of ICT tools and/or ICPM systems on geographically dispersed (remote) civil and building construction projects..

This study aims to assess the impact of adopting selected green construction site practices on the health and safety performance of the construction projects. The impact of storm-water management, energy management and construction waste management on projects health and safety performance was also examined.

A survey was conducted to collect information from Class A contractors in Nigeria, and 168 usable responses were received. The data were analysed using the partial least squares (PLSs) structural equation modelling technique.

The findings indicate that energy management and waste management practices have significant effects on the health and safety performance of the construction projects, while storm-water management has no effect.

Project and site managers need to take into consideration the skill set of their workforce when attempting to adopt new innovative construction strategies the workers are unfamiliar with in a changing construction environment. There is also a need for more training of workers on generic and specific green skills to avoid health and safety challenges on site.

The findings of this study make significant contribution to the debate on the health and safety performance of green projects, as only a few studies have been conducted on this topic. The empirical relationships between the constructs of energy management, waste management, storm-water management and health and safety performance are unique in the context of other related studies and have advanced the body of existing knowledge.

When there is a cordial relationship among the members of the smart city team, there are bounds to be achievements and executions of projects within stipulated time of the budget allocated. The partnership in ideas and overall discipline will propel the activities involved in executing smart cities in the world. In identifying not just the definitions of smart city, the developmental aspect of the concept is considered across phases of construction as the industry strives towards elegance and advancement. However, exciting as it comes in benefits and enhancement in the quality of life, several problems have also been identified albeit opportunities are somewhat presented in the challenges when analysed thoroughly from the inception to completion. The interaction within team members across countries will pave way for collaborators into the system.

The purpose of this paper is to investigate the nature of qualitative construction partnering research.

In total, 20 qualitative peer-reviewed papers about construction partnering research are reviewed.

The results show four methodological gaps. All identified gaps have in common that specific time and place dependent details that may have influenced understanding of studied individuals are underexposed.

The main limitation of this study is that empirical-based papers are divided into either qualitative or quantitative research, but the boundary between those categories is not as black and white as it may look like in first instance.

The identified gaps are translated to recommendations for further study. This will help the reader to become more aware of the difficulties and decisions encountered by the researcher, and in that way the reader is more aware and gains more understanding of the context-related character of the study. Applying the recommendations will lead to different conclusions and recommendations to improve construction partnering in working practice.

More focus on local time- and place-dependent factors of the studied individuals as well as the process of studying it, inevitably leads to encountering (and becoming more aware of) personal, subjective and unexplainable decisions and behavior. Describing and analyzing these personal, subjective and unexplainable points in the research process will improve the quality of the research.

This study contributes to the further development of academic research on this topic and increase effectiveness of partnering in the construction sector.

The demand for power has surged in recent times and continues to increase yearly. In comparison to developed countries, the power industry’s risks, especially in piblic–private partnership (PPP) projects, are more complex and essential in developing countries. Appreciating the inter relationship among these risk factors is crucial. However, there exist no studies developing quantitative models to explain how various PPP power risk factors influence each other, especially in developing countries like Ghana. This study aims to investigate and model the relationship, the probability of occurrence and severity of impact of PPP power risk factors in Ghana.

Data were collected through ranking type questionnaire in a two-round Delphi survey with 48 respondents using purposive and snowball sampling techniques. partial least squares structural equation modelling (PLS-SEM) was used for analysis of data.

A model was developed to investigate the influence the risk factors inherent in PPP power projects have on each other. Validity of the model was tested based on the data collected. PLS-SEM results indicated the various relationships and interdependencies the risk factors had on each other considering their probability and severity. Both significant and insignificant levels of relationships were found among the various risk factors.

The SEM that was developed to assess the relationships among the risk factors has great value for policy makers in the energy sector, industry practitioners, researchers and industry practitioners. Strategies can be mapped out to mitigate and effectively allocate the risks with the high interdependencies.

Regarding the quantitative impact of the interrelationship among risk factors in PPP power projects, the findings of this research are arguably the first to be presented for the construction sector and contribute to knowledge on PPP practice and further has implications toward achieving power sector risk mitigation.

Studies focusing on the growth of indigenous construction firms (ICFs) are getting dated, and unreflective of recent policy changes in developing countries. This study sought to analyze critical barriers to the growth of ICFs and obtain an unsupervised parsimonious grouping of the barriers for policy improvements.

A mix of quantitative and qualitative research methods was adopted for the study. ICFs in Nigeria were cross-sectionally surveyed based on a set of firm growth barriers obtained from literature and refined by focus group discussion. Descriptive (means, standard deviations, percentages) and inferential (Kruskal-Wallice and Mann-Whitney U test) statistics were used in the analyses of the data. Factor analysis was used to group the variables.

Results showed that “declining” ICFs are more negatively impacted by low construction mechanization/use of labor intensive methods, inadequate geographical reach of operations, and inadequate flow of jobs/low demand than “stunted” and “growing” ICFs. The three main domains of critical barriers to the growth of ICFs were identified in descending order of importance as low patronage, difficulty accessing funds, and business management incapacity.

The study recommends improvements in access to funds for ICFs by increasing the percentage of advance payments, and creating a pool of equipment for easy hire by ICFs. ICFs are advised to seek information on tendering opportunities outside their regions of domicile in order to increase their patronage.

This study reveals differences in the impacts of growth barriers on ICFs at different growth levels. This study also clarifies persisting barriers to the growth of ICFs [primarily construction micro, small and medium-sized enterprises (MSMEs)] from a developing country perspective using a longer list of variables.

The purpose of this research is to identify the key aspects present in collaborative projects with the objective of producing a clear definition for collaboration within the UK construction industry. Firstly, the research provided a summary of the different forms of “working together” that have become more prevalent since Latham's and Egan's work. Partnering was seen as the ultimate form of collaboration, but due to the recent economic crisis, it has enjoyed diminishing support. Collaboration was perceived as the new way forward. However, the literature on the subject often used the term “collaboration” interchangeably with partnering, alliances, joint ventures, and networks. Therefore, the aim of this research is to identify what the meaning of collaboration is currently.

Primary research was carried out in order to provide a clearer picture of what collaboration is. Both qualitative and quantitative data was collected through a triangulation of questionnaires and interviews. Selective samples of personnel were approached to take part in interviews to identify aspects of collaboration which were subsequently used to produce a questionnaire. A larger selected sample of personnel was then approached to complete the questionnaires. All personnel in the sample were selected as they had been involved in collaborative construction projects. Semi structured interviews were used to provide a list of aspects to collaboration. The aspects were then ranked in importance based on the analysis of results from an online questionnaire. The aspects were then grouped into those that were considered essential; for those that were considered desirable and those that merely added an extra dimension to collaborative working.

The interviews produced a list of 48 aspects which the participants considered were relevant to collaboration. Through the use of online questionnaires, the 48 aspects were rank ordered and the essential aspects to collaboration identified. The rank ordered list of aspects was then used to inform the definitions of collaboration.

The findings of this research indicated that there are a large number of aspects that are associated with collaborative working. However, the results provide an indication of which of the many aspects identified are essential if a collaborative environment is to be established.

The increasing consciousness of environmental protection has fostered the development of environmental management systems (EMS). ISO 14001 is an international standard that provides guidance for the establishment and monitoring of EMS implementation. Investigates the development of environmentally‐friendly construction operations based on a recent study in Hong Kong. Contributes to identifying the elements and processes of EMS implementation, and explaining the procedural guideline of a seven‐step EMS approach in managing construction practice. Incorporating the compliance requirements of ISO 14001, the approach addresses the policy, the implementation and monitoring, and continuous improvement of construction operations. The tangible and intangible benefits of the approach are also discussed with reference to the experiences of the Housing Department in Hong Kong. The approach may also be useful for construction practitioners to manage the EMS processes and assess their environmental performance towards continuous improvement.
