Abstract
This study investigates the cost and time performance of highway projects from the viewpoint of the public owner. It differs from previous studies which focused on the contractor’s perspective on project performance. A total of 13 success factors were identified from literature and the opinions of experienced engineers. Data was collected from 99 projects handled by the Department of Highways (DOH) in Thailand Discriminant analysis was used in this study to build the cost and time predictive models, which were generated from samples of cases, which had already been grouped and known as successful and unsuccessful projects. The models were then applied to new cases with measurements for the predictor variables, to predict that the projects were either successful or unsuccessful. The results show that success in cost performance depends on the management of construction resources, budget management, construction method, and communication. By contrast, schedule management and human resource management inhibit cost performance. Success in time performance depends on choice of construction method, management of construction resources, schedule management, supervision and control, and communication. Quality management, budget management, human resource management, owner involvement, and team relationships impede time performance

Abstract
Construction projects in Nigeria are generally characterized by cost and time overrun, substandard work, disputes and abandonment; emanating from several factors of which the wrong choice of contractors is a key factor. This study evaluated the criteria adopted by clients and consultants in contractors’ selection in Nigeria. Data were collected with the aid of questionnaire administered on clients and consultants within the Nigerian construction industry. Also prequalification/bid evaluation scores for eighty contractors were collected based on the criteria used in assessing them. The data collected were analysed with the aid of mean score and regression analysis. The result showed that past performance; contractors’ experience; workmanship quality; tender sum; and plant and equipment were the most important criteria for contractors’ prequalification/bid evaluation in Nigeria. A contractors’ selection model was eventually derived based on some of the identified factors. The goodness of fit of the model as defined by the value of r2 was found to be 99%. This therefore implies that only 1% is explained by other independent variables not included in the regression equation; hence the suitability of the model for contractors’ selection in Nigeria.

Abstract
The purpose of this research is to explore and test conceptual issues of how communities of practice (CoPs) are a recognized means of transferring knowledge. Analysis of data, derived from reflection upon experience gained by close full‐time engagement on three complex, large‐scale engineering construction projects. Five emerging themes that help to explain how CoPs may be nurtured to increase the effectiveness of project management are revealed: creating a knowledge environment, discovering and recruiting potential members, information sharing, time for communicating, and motivation and rewards. The development of CoPs requires time and the creation of a knowledge environment. In the complex world of international construction, most projects are unique physical undertakings, have teams that have never worked together before, have a limited duration, with participants located in numerous countries. Thus, there is a natural tension between the need and the reality that requires strong cross‐cultural leadership, and special techniques, if CoPs are to be utilized. This paper practically illustrates, based on rigorous organizational literature theory largely missing from the engineering community, how CoPs can be actually nurtured and used. The metaphor used to illustrate this should resonate strongly with construction engineers and designers.

Abstract
Purpose
Management capability is one of the major criteria for evaluating construction contractors during prequalification and tender evaluation This paper aims to investigate the impact of contractors' management capability as a prequalification criterion on cost and time performance of selected building projects.
Design/methodology/approach
Prequalification assessments of management capability of wining contractors as well as cost data relating to 77 completed building projects executed between 2004 and 2007 are obtained. The data obtained from a questionnaire and archival data are analyzed using one‐way analysis of variance and multiple regression.
Findings
The results reveal that contractors' management capability has significant impact on cost and time performance of building projects as evidenced by p‐values of 0.042 and 0.039, respectively.
Practical implications
The research could be of significant benefit at the research implementation stage of public procurement practice especially in relation to the construction industry in Nigeria. Construction practitioners involved in prequalification and tender evaluation should continue to seek relevant information relating to management capability from the candidate contractors during prequalification and tender evaluation.
Originality/value
Models capable of predicting the final cost and duration of building projects are eventually derived based on prequalification assessment of contractors on management capability, proposed contract duration and the initial contract figure. The goodness of fit of the models as defined by the value of R2 is found to be 96.2 percent and 90.01 percent for cost and time, respectively; thus signifying high predictive efficacy of the models.

Abstract
In this chapter we examine various human resource management (HRM) implications involved in the leadership of fluid teams. Leadership of fluid teams, which are distinguished by their dynamic composition, requires consideration of issues that may not be as pertinent for stable teams. In particular, we focus on the concept of familiarity. Composing and leading teams with members exhibiting varying degrees of familiarity with one another creates obstacles to effective and efficient functioning and may ultimately lead to poor performance. With this in mind, leaders must pay particular attention to issues of coordination, and composition such that a broad range of generalizable teamwork skills exists within the team. Within this chapter, we explain the concepts of fluid teams, team leadership within fluid teams, and other relevant concepts related to the formation of familiarity. Next, we thoroughly review extant empirical and theoretical research within these areas. We identify areas of correspondence among the various concepts and findings of the reviewed studies and generate an integrated model of fluid team leadership. To conclude, we highlight the distinct HRM implications associated with the use, and leadership, of fluid teams.

Abstract
This chapter discusses the involvement of procurement in smart city development. Procurement plays a vital role in the development of strategies in planning, and execution in the construction industry. This is further introduced into smart city to find the best possible methods of bringing the ideas behind smart city into realisation. The common procurement methods are explained along with their involvement in smart city. Common drawbacks to smart cities procurement and measures to challenges in the procurement of smart city are also explicitly explained in the chapter. Through an identified and accepted procurement method into smart city, the processes involved in executing smart city will be the ones with directions and proper planning.

Abstract
Purpose
This research aims to examine the role of knowledge sharing (KS) as mediation in the relationship between transactional leadership (TSL) and organizational creativity (OC) among construction workers in Jakarta.
Design/methodology/approach
The population in this research was the construction workers working in Jakarta. The sample used in this research consisted of 210 respondents. The validity of the hypothesis model was analyzed using the structural equation modeling–partial least squares (SEM-PLS) approach with the help of SmartPLS 3.2.8.
Findings
TSL affects KS and OC. Another most important thing is that KS acts as a partial mediator for the relationship of TSL to OC.
Originality/value
Originality in this research is the use of variable KS to mediate the relationship between TSL and OC in the research conducted in the scope of construction in Jakarta. Other theoretical implications for TSL are added by this research. This research has never been conducted in the construction sector in Jakarta, Indonesia.

Abstract
Purpose
The construction industry is beset with unethical behaviours. Although several studies have investigated the effects of unethical behaviours on project performance, research in the Ghanaian construction industry (GCI) remains scant. Consequently, this research assesses the interactive effects of ethical and unethical behaviours of construction professionals on project performance in the GCI.
Design/methodology/approach
A quantitative research approach was used to obtain primary data from 68 construction professionals, viz, quantity surveyors, architects, civil engineers, clerk of works and project managers, via a closed-ended questionnaire survey. Data collected were analysed using one-sample t-test and Kruskal–Wallis test statistics, after which two hypotheses were tested and validated using regression analysis.
Findings
Reduction of project risks, avoidance of legal problems and maximisation project quality performance were critical effects of ethical behaviours observed on project performance, whereas the effects of unethical behaviours such as cost overrun, abandonment and time overrun were severe on project performance in the GCI. Ethical behaviour was seen to relate to project performance positively, and unethical behaviour was proved to have dire consequences on project performance.
Practical implications
Construction project performance is greatly influenced by professionals' ethical and unethical behaviours. Emergent findings emanating from this research will assist emerging economies in developing and implementing counter policies and systems that mitigate the unethical behaviours of construction professionals.
Social implications
The study highlights the effects of ethical and unethical behaviours on project performance to reorient individuals' perceptions that unethical behaviours are less critical in the construction industry. Supporting evidence encourages individuals to adhere to ethical behaviours in a project environment.
Research limitations/implications
The inability to obtain data across the entire geographical spread of Ghana is acknowledged as a major limitation of the study and affects the generalisation of the results.
Originality/value
This study constitutes a first attempt to establish the interactive effects of ethical and unethical behaviours of construction professionals on project performance within the GCI. A significant addition to the body of knowledge is that ethical and unethical behaviours impact project performance positively or negatively, respectively.

Abstract
Purpose
The aim of this study is to investigate the reasons for disparity between design stage elemental cost plan and final tender sum (contract sum) in building procurement. A number of risk factors responsible for such variation were identified through case study projects from which data were extracted.
Design/methodology/approach
Literature review determined the risk factors inherent in the preparation of design stage elemental cost plan. Interviews and thematic analysis identified the risk factors responsible for the disparity between design stage elemental cost plans and final tender sums. Analysis of documents obtained from the archives of study participants (consultant quantity surveyors) complemented responses from the interviews.
Findings
The review revealed a number of inherent risks in the design stage elemental cost plan development. The interviews further indicated that risks have an impact on and are responsible for the deviations experienced. The assessment of these risk elements could assist in determining the final tender sum from cost plans.
Research limitations/implications
Findings revealed disparity between elemental cost plans and final tender sums in the region of −14 and +16 per cent. The risk factors identified were responsible for the deviations observed. With this information, Quantity Surveyors are more able to accurately forecast final tender sums of building projects from cost plans through proper risk identification and analysis, thus increasing the accuracy of design stage elemental costing.
Originality/value
To the best of the knowledge of the researchers, there is no recent documentary evidence of an investigation into the reasons for disparity between design stage elemental cost plan and final tender sum in traditional building procurement in New Zealand construction.

Abstract
Purpose
Cost estimating process is an important element within the project life cycle. Comprehensive information, expanded knowledge, considerable expertise, and continuous improvement are needed to obtain accurate cost estimation. The purpose of this paper is to identify the critical factors that affect accuracy of cost estimation and evaluate the degree to which these factors are important from contractors’ and consultants’ viewpoints.
Design/methodology/approach
Qualitative and quantitative research approaches were adopted in collecting and analyzing the data, and testing the hypotheses. Based on the literature review, a questionnaire was prepared and then was modified according to the results of face-to-face open-ended interviews conducted with 11 project managers. The final version of the questionnaire was distributed to a random sample of 265 respondents. For analyzing the collected data Kendall’s and Mann-Whitney tests were conducted.
Findings
The analysis revealed that there is a strong agreement between contractors and consultants in the ranking of the factors related to consultant, contractor, design parameters, and information. A slightly weak agreement between contractors and consultants was noted regarding the factors related to market conditions (external factors) and factors related to project characteristics. Furthermore, the results show that the top ten factors affecting the accuracy of cost estimate are clear and detail drawings and specification, pricing experience of construction projects, perception of estimation importance, equipment (cost/availability/performance), project complexity, clear scope definition, accuracy and reliability of cost information, site constraints (access, storage, services), material availability, financial capabilities of the client, and availability of database of bids on similar project (historical data).
Originality/value
Offers an original view of the concept of accuracy of cost estimates as it relates to the efficiency of the project relying on both literature review and empirical evidence.
