Abstract
Purpose
The purpose of this paper is to develop a quantitative comprehensive model for construction project success evaluation, from the viewpoint of a contractor company.
Design/methodology/approach
In this paper, the authors used a comprehensive definition of project success consisting of two components: Product success, which deals with the effect of the project's final product; and Project Management success, which focuses upon the project process. The research methodology includes five steps: identification of the critical performance indices for the two above mentioned components; quantification of the performance indices; normalization of the indices; integration of the various performance indices to develop an overall project performance function; and applying the model on a real project in Iran and analyzing the results.
Findings
This paper introduces a novel model to evaluate and measure the construction project success from the viewpoint of a contractor company. The results show that this model can be used as a reliable tool to measure the project performance of contractors and their points of strength and weakness can be determined precisely.
Practical implications
Analyzing the results of the case study shows that the evaluation model is absolutely applicable. All necessary elements to quantify the critical performance indices and overall project success can be recorded precisely and easily. Thus, this model can be used in every contractor company concerned about its projects’ performance.
Originality/value
The evaluation model proposed in this paper is a unique and comprehensive quantified model which considers difference between project success and project management success and all critical indices which can affect them.

Abstract
Purpose
Since 1960, many public–private partnership (PPP) projects have been implemented in Hong Kong. Some projects have been considered as very successful, whereas others are seen as less successful. Unfortunately, these success outcomes have remained abstract because they are not in quantifiable terms. This paper aims to develop a model that can quantify the success outcome of PPP projects in Hong Kong.
Design/methodology/approach
Both quantitative and qualitative research approaches were adopted for the study. First, a questionnaire survey was conducted with PPP practitioners in Hong Kong, and thereafter, the fuzzy synthetic evaluation technique was used to develop a project success index for PPP projects in Hong Kong. The Hong Kong Cross-Harbour Tunnel project was used as a case study to demonstrate the applicability of the pragmatic model.
Findings
The success index model developed consists of four unrelated success criteria groupings: cost effectiveness, quality of services and technical specification, environmental impact and long-term partnership. Further, the computed success index for the Cross-Harbour Tunnel project is 4.06, which indicates that the tunnel project has been highly successful.
Originality/value
The outputs of this study will enable PPP practitioners in Hong Kong to reliably evaluate the success levels of their projects. In addition, local practitioners can now compare the success levels of two or more PPP projects on the same basis.

This paper aims to develop a project success index (PSI) to benchmark the performance of building maintenance projects from a number of key performance indicators (KPIs).
Abstract
Purpose
This paper aims to develop a project success index (PSI) to benchmark the performance of building maintenance projects from a number of key performance indicators (KPIs).
Design/methodology/approach
The research collected 110 responses from project participants with managing building maintenance project experience of the Hong Kong construction industry via ordinary postal mail. In addition, a project success equation was formulated from the principal components analysis to generate a composite score so as to indicate the level of success of building maintenance projects.
Findings
Industry participants believe that time, cost, quality, functionality, safety and environmental friendliness can be considered as KPIs for building maintenance projects. A single index can also be computed from the project success equation to apply different weightings to the respective KPI with different significance such that the performance of building maintenance projects can be compared.
Practical implications
The concept of success remains vague among project participants, which makes it difficult to assess whether the performance of a project is a success or failure. The development of PSI can indicate the overall performance of a building maintenance project and quantify the success concept in a scientific manner.
Originality/value
PSI‐Mains indicates the success level of a building maintenance project for benchmarking purposes. It also enables project stakeholders to measure the success of a building maintenance project and to compare the relative success level among different building maintenance projects in a scientific manner.

Abstract
Purpose
The paper aims to develop a project success index (PSI) to benchmark the performance of design‐build projects from a number of key performance indicators (KPIs).
Design/methodology/approach
This research collected 92 responses from Design and Build (D&B) project participants of the Hong Kong construction industry via ordinary postal mail. In addition, a project success equation is formulated from the principal components analysis.
Findings
D&B project participants suggests that time, cost, quality and functionality should be the principal success criteria for D&B projects. A single index can also be computed from the project success equation to apply different weightings to the respective KPI with different significance.
Practical implications
The concept of success remains vague among project participants, which makes it difficult to assess whether the performance of a project is a success or failure. The development of PSI can quantify the success concept in a scientific manner.
Originality/value
PSI indicates the success level of a construction project for benchmarking purposes. It also enables project stakeholders to measure the success of a D&B project and to compare the relative success level among different D&B projects in a scientific manner.

Abstract
Purpose
Successful implementation of infrastructure projects has been a controversial issue in recent years, particularly in developing countries. This study aims to propose a decision support system (DSS) for the evaluation and prediction of project success while considering sustainability criteria.
Design/methodology/approach
To predict sustainable success factor, the study first developed its sustainable success factors and sustainable success criteria. These then formed a decision table. A rough set theory (RST) was then implemented for rules generation. The decision table was used as the input for the rough set, which returned a set of rules as the output. The generated rulesets were then filtered in fuzzy inference system (FIS), before serving as the basis for the DSS. The developed prediction tool was tested and validated by applying data from a real infrastructure project.
Findings
The results show that the developed rough set fuzzy method has strong ability in evaluation and prediction of the project success. Hence, the efficacy of the DSS is greatly related to the rule-based system, which applies RST to generate the rules and the result of the FIS was found to be valid via running a case study.
Originality/value
Use of DSS for predicting the sustainable success of the construction projects is gaining progressive interest. Integration of RST and FIS has also been advocated by the seminal literature in terms of developing robust rulesets for impeccable prediction. However, there is no preceding study adopting this integration for predicting project success from the sustainability perspective. The developed system in this study can serve as a tool to assist the decision-makers to dynamically evaluate and predict the success of their own projects based on different sustainability criteria throughout the project life cycle.

Abstract
Purpose
This paper aims at studying the success and failure of BPR projects executed throughout Iran. For this purpose, effective indices and also factors of success and failure are to be investigated.
Design/methodology/approach
Based on statistical analysis of efficiency indexes mean value and project effectiveness, as well as the test outputs for the projects' total success, it was proved that except for the two organizations, the rest lack necessary efficiency and except for two organizations, the others lack necessary effectiveness.
Findings
The total success test outputs has verified the results of the two above‐mentioned tests, so by 95 percent of assurance, it has to be commented that BPR projects executed in Iran have failed to reach predefined acceptable success.
Practical implications
The lack of data from organizations is a big problem in BPR projects in Iran.
Originality/value
The article recommends that every BPR project before execution needs deployment of success factors such as: preparation for change, planning, recognition and design, evaluation, culture and change, information technology, and outcome in governmental organizations.

Abstract
Purpose
Public–private partnerships (PPPs) are viewed as a reform tool for resolving inefficiency and absence of dynamism in water supply delivery in developing countries. However, the requirements for their successful implementation have received very little attention. This paper aims to describe a set of critical success factors (CSFs) that, when given special and continual attention, would ensure a successful project implementation and to provide a predictive tool to aid implementers to evaluate the likelihood of a successful PPP water supply project.
Design/methodology/approach
Fourteen perceived CSFs were initially derived from project cases and extant literature, and verified through a two-round Delphi survey. Factor analysis established five critical success factor groups (CSFGs) that were then used to develop a fuzzy synthetic evaluation tool for assessing the chance of a successful project.
Findings
The five key CSFGs are commitment of partners, strength of consortium, asset quality and social support, political environment, and national PPP unit. The model output showed that, overall, these factors have a “very high” positive impact on a successful implementation of a water supply project. Hence, there is an excellent correlation between achievement of the CSFGs and project success. Success indices of individual principal factors are also “very high”.
Originality/value
The study presents a tool to public clients and private audience, and it is hoped that the study will trigger policy development towards PPP practice in developing countries, because these findings have wider implications for legal and regulatory systems, public capacity, financing, public procurement and politics.

Abstract
Purpose
Public-Private Partnership (PPP) model still contains the obstacle in partnership, which can lead to different satisfaction between project participants. Therefore, project managers need to consider stakeholder satisfaction to ensure success in PPP implementation. However, this problem is limited in the previous studies in developing countries. The purpose of this study is to evaluate stakeholder satisfaction of PPP transport projects in developing countries.
Design/methodology/approach
A total of 15 satisfaction factors were identified and four main groupings were introduced by a review of the literature and expert interview rounds, including satisfaction of general public, satisfaction of private sector, satisfaction of government and satisfaction of end-users. A PPP expressway project in Vietnam was used to illustrate for this analysis. Data were collected through a questionnaire survey with 31 validated responses. The fuzzy synthetic evaluation method was then applied to evaluate satisfaction index for the stakeholder satisfaction of PPP transport projects in Vietnam as a developing country.
Findings
The analyzed result showed that the project participants are basically satisfied with gained outcomes of the experimental project with the satisfaction index = 3.46. Specifically, the general public expressed that they are “satisfied” with satisfaction index = 4.08. Meanwhile, end-users, government and private sector are “basically satisfied” with the project outcome (the satisfaction index of 3.31, 3.16 and 3.04, respectively).
Originality/value
This study provides more depth understanding of the satisfaction factor with transport infrastructure service in developing countries through PPP procurement. In addition, the decision-makers might utilize this evaluation model for rating the stakeholder satisfaction of real PPP projects to ensure project success.

Abstract
Purpose
This paper aims to help understand how adopting risk allocation criteria impacts the delivery of public–private partnership (PPP) mass housing in Nigeria with the view of promoting the adoption of PPP housing scheme in Nigeria.
Design/methodology/approach
The research design adopts the census sampling approach by using well-structured questionnaires distributed to stakeholders involved in PPP-procured mass housing projects, i.e. consultants, in-house professionals, contractors and the organized private sector, registered with PPP departments in the Federal Capital Territory Development Authority, Abuja, Nigeria. Sixty-three risk factors, nine risk allocation criteria and nine project delivery indices were submitted for the respondents to rank on a Likert scale of 7. Two hypotheses were formulated to test whether the risk allocation criteria impacted PPP mass housing delivery or otherwise. The study adopts partial least square-structural equation modeling to model the effect of risk on risk allocation criteria on project delivery indices and risk severity.
Findings
The finding shows that project risk allocation criteria have less effect on project delivery indices than on risk severity. The study concludes that risk allocation principles do not directly affect the delivery of PPP-procured mass housing projects. This is evident by the path coefficient of 0.724 values, which is not statistically significant at a 5% alpha protection value. The study concludes that allocating critical risk factors influences the performance of PPP-procured mass housing projects, as the path coefficient of 0.360 is also not significantly far from 0 and at a 5% alpha protection value.
Originality/value
The study is one of the recent studies conducted in PPP-procured mass housing projects in Nigeria owing to the novelty of procurement option in the sector. It highlights the risk factors that can jeopardize the PPP-procured mass housing project objectives. The study is of immense value to PPP actors in the sector by providing the necessary information required to formulate risk response methods to minimize the impact of the risk factors in PPP mass housing projects.

This paper presents a sustainability assessment model to holistically guide sustainable construction and green retrofitting of affordable housing from the Ghanaian perspective.
Abstract
Purpose
This paper presents a sustainability assessment model to holistically guide sustainable construction and green retrofitting of affordable housing from the Ghanaian perspective.
Design/methodology/approach
A comprehensive review was carried out, which yielded 16 sustainability indicators. Then, a questionnaire survey was conducted among respondents in the Ghanaian housing sector. Forty-seven valid responses were received and analysed using fuzzy synthetic evaluation (FSE) technique.
Findings
A four-index model was developed that includes: Housing and Transportation (H + T) index, household-satisfaction index, efficient stakeholder-management index and quality-related index. These indices account for 25.3%, 26.3%, 23.6% and 24.9% of sustainability attainment in affordable housing, respectively. Accordingly, household-satisfaction has the greatest contribution to sustainability attainment in affordable housing.
Research limitations/implications
Due to challenges in obtaining responses to the questionnaire, the study was conducted with relatively small number of responses.
Originality/value
The model serves as a tool that could be used to objectively and comprehensively assess sustainability performance in affordable housing. Besides, it could be used as a baseline to calibrate future projects and for benchmarking success levels of comparable housing projects. Finally, the estimated indices are applicable in decision making for optimum resource allocation for sustainable low-cost housing in the Ghanaian perspective.
