Sustainable public transport systems may be achieved by adopting electric bus locomotion. The problem being addressed by this research is the development and case application of a computation methodology of the social benefit cost ratio of an electric bus transport project in India and identification of whether it can significantly favour the situation of environment friendly transport. The underlying theory behind this approach is if the environmental and social dimensions of an infrastructure project are considered in addition to the financial dimensions for the purpose of project appraisal, a holistic evaluation can be achieved and such an evaluation can give an edge to the approval of environmentally friendly projects. The evaluation has been performed using the present worth analysis of various types of benefits and costs associated with the implementation of the electric bus rapid transit system in a city. The variables considered in the researched methodology are benefits which are revenue, savings in vehicle operating costs (VOC), environmental benefits, savings in travel time, reduction in accidents and non-consumption of fossil fuel, and costs which are infrastructure investment costs, cost of the bus fleet, maintenance cost, replacement costs, cost of system operation and maintenance and additional electric power generation. The outcome as indicated by the value of the social benefit-cost ratio (SBCR) illustrates that such projects can be positively justified from point of view of the benefits gained by the society as well as fruitful returns and value addition of infrastructure investment in the long run. The research contributes by validating that social benefit-cost analysis (SBCA) can be used for the evaluation of sustainable transport system appraisals in order to make their realisation more favourable.

The establishment of the forestry educational centre is a good effort made to protect and conserve the forest as well as assisting the public in understanding the landscape changes and sensitivity towards its sustainability. However, there are lacks of consciousness and obligation of the important of landscape conservation in the context of development planning that causes the problem of effective implementation of a conservation strategy exists. Therefore, this paper aims to discuss forest landscapes conservation, particularly in Malaysia with the objectives of to analyse the current landscape features of selected forestry educational centres and to increase awareness among the stakeholders on the importance of conserving and preserving forest landscape towards its sustainability. The study was conducted using two methods specifically via a case study where the Sultan Idris Shah Forestry Education Center (SISFEC) was selected and field observations were conducted to analyse the existing physical condition of the study site. Findings have indicated that SISFEC has successfully conserved the existing landscapes and delivered awareness and knowledge on forest conservation and preservation to the public through several activities such as forestry camps, nature walks, and environmental education programmes. On the other hand, the findings also suggested that the forestry management should give higher priority in maintaining the manmade landscape image of the forest and plan their activities well through good monitoring and efficient management planning which will ensure the site's sustainability in future.

The quest for delivering successful construction projects has urged South African small and medium enterprises (SMEs) to adopt risk management in their projects. However, it has been evinced that SMEs projects in South Africa especially in the Gauteng province have encountered poor performances. Thus, this article determines core risk management factors influencing project outcome of SMEs. A deductive approach was embraced using a questionnaire. The data were collected from 181 conveniently sampled respondents in Gauteng, graded from Grade 1 to 6 of the CIDB (Construction Industry Development Board) grading system. The Statistical Package for the Social Science (SPSS) version 23 was used to analyse the data by computing exploratory factor analysis and multiple regression analysis. It was revealed that SMEs performance outcome is influenced by eight risk management factors. The influential factors are organisational environment, defining project objectives, resource requirements, risk measurement, risk identification, risk assessment, risk response and action planning and monitoring, review and continuous improvement. The risk management factors established in this article are reliable and valid in projects undertaken by SMEs in the South African construction industry and the findings can serve as a guideline for contractors to achieve success in this context. The study may be repeated in other countries globally, however, it cannot be generalised due to the restrictions pertaining to the geographical area.
为了实现成功的建设项目，南非中小型企业(SMEs)在其项目中采用风险管理。然而，有证据表明，南非特别是豪登省的中小企业项目表现不佳。从而确定影响中小企业项目成果的核心风险管理因素。通过问卷调查，采用了演绎法。数据收集自豪登省的181个方便抽样的受访者，根据CIDB(建筑业发展委员会)的评分系统分为1到6级。采用SPSS (Statistical Package for The Social Science)第23版对数据进行计算探索性因子分析和多元回归分析。结果表明，中小企业绩效结果受8个风险管理因素的影响。影响因素包括组织环境、确定项目目标、资源需求、风险度量、风险识别、风险评估、风险应对和行动计划与监控、审查和持续改进。本文中建立的风险管理因素在南非建筑业中小企业承担的项目中是可靠和有效的，研究结果可以作为承包商在这种情况下取得成功的指导方针。这项研究可以在全球其他国家重复进行，但是，由于地理区域的限制，它不能推广。

This article aims to identify the status of construction industry practitioners in Indonesia in terms of their knowledge and current practices as well as the barriers for implementing Building Information Modelling (BIM). This study utilises a questionnaire survey, aimed at the construction industry practitioners in Indonesia. The result shows that BIM is still a novelty for the construction practitioners in Indonesia. This is backed with the finding that more than 60% of the respondents was not familiar with BIM terminology or did not have proper knowledge of BIM terminology. More than 70% of the respondents' projects have implemented BIM Level 1, mostly in transportation service, energy production and distribution, roads and bridges, and the building infrastructure category. The five highest ranks of barriers to BIM implementation are lack of BIM training, lack of BIM experience and capability, no client demand, high cost in software and hardware acquisition, and inadequate information technology (IT) facilities. The recommended strategy should be initiated by the government, by conducting a comprehensive familiarisation programme covering BIM knowledge, BIM advantages and BIM implementation in the industry. At the same time, the government should prepare regulations and standards as guidance to BIM implementation in Indonesia.

In the current competitive and complex business environment, innovation in the construction industry is vital. In this sense, integrated project delivery is an emerging delivery system for construction projects; however, implementing this system requires some enablers to enhance its implementation. Until now, no study has been conducted to identify what enablers can lead to proper integrated project delivery implementation. Therefore, this study aims to identify and to classify integrated project delivery implementation enablers. In this study, a comprehensive list of integrated project delivery implementation enablers has been developed using an in-depth literature review. Besides, integrated project delivery project managers, employers, consultants, contractors and engineers participated in a survey. The obtained results were analysed using exploratory factor analysis method. Thus, the study findings illustrated that organisational enablers are considered essential enablers, followed by environmental, contractual and technical enablers. The significance of this research is the identification and classification of integrated project delivery implementation enablers, which will provide valuable information to develop integrated project delivery implementation strategies. Additionally, the results of this study can be a proper roadmap to support developing countries to adopt the integrated project delivery approach for project developments.

This article presents a study of the contractors' preference for formwork system selection in Indonesian context. As decision makers, contractors are faced with challenges in choosing the formwork system for a particular project. While conventional timber formwork has been the most used formwork system in Indonesia, aluminium formwork is present although it has not been widely used. Thus, this research investigates the current practices of available formwork systems and its selection criteria in Indonesia. A decision-making framework (DMF) is developed by considering the appropriate assessment criteria for formwork system selection. This framework is then implemented through analytic hierarchy process technique. The result shows that contractors tend to choose aluminium formwork with a preference at 79% compared to conventional timber formwork with a preference at 21%. These findings can be used as considerations for contractors to start using aluminium formwork due to its excellence compared to conventional timber formwork. This study also proves that the proposed DMF can be applied and provides a sound decision related to formwork system selection.

Chinese enterprises are presently dominating various sectors of businesses abroad, offering a wide range of low to high-end quality products and services. The construction sector in Africa is now being dominated by Chinese multinational contractor companies, who find in Africa their next preferable market to grow. The available literature on the field has serious gaps in explaining which organisational strategies increase the competitive advantage and the market dominance of Chinese multinational contractors, especially in the Southern African region. This research aims to uncover the organisational strategies, implemented by Chinese multinational contractors operating in the Southern African region, who have paved the way and consolidated their success in the region. Through a mixed methods process, qualitative and quantitative data are obtained. The construction markets of the Southern African region are analysed (environmental analysis) and the main multinational Chinese contractors are identified, through a literature review and organisational analysis. Several organisational strategies are shortlisted and, finally, through an online questionnaire, the opinions of the participants to rank the organisational strategies previously identified in terms of contribution to the actual success, copying capability, etc., are carried out. The findings revealed that the capability to offer a lower price for construction services, the easy access to loans and funds from the organisation's home government and the capability to trade debt for local resources, such as wood, land and minerals are the organisational strategies that mostly contributed to the recent Chinese contractor dominance in the Southern African construction market.

This study intended to examine the influence subcontractor risk management has on the quality performance of building construction projects. Using a quantitative research method, five hypothesised constructs were tested. The views of 139 Heads of Works for Metropolitan, Municipal and District Assemblies (MMDAs) in Ghana were elicited using a structured questionnaire. A confirmatory factor analysis (CFA) based on structural equation model (SEM) was adopted in analysing the data obtained. The findings suggest that the management of four (financial risks, resource risks, technical risks and managerial risks) out of the five categories of risks positively influenced the quality performance of building construction projects. Relationship risks showed no significant influence on construction quality performance. The study showed quantitatively the effects of sub-contractor risks on quality performance. It provides a vivid relationship between the concept of sub-contracting and quality performance. Therefore, failure to properly manage risks sourced from sub-contractors on a building construction project will have a major adverse consequence on the quality performance of the project. This study further advances efforts at understanding the link between sub-contractor management and project performance with a particular focus on the management of risks emanating from the use of subcontractors on building projects.

The residential sector of Algeria consumes 29% of the total energy consumption. In order to reduce and address this consumption along with the challenges of climate change, the Algerian public policy considers energy efficiency investment measures (EEIMs) in the residential sector as a key factor. However, despite the recommendations and incitement measures from the government, the adoption of EEIMs of Algerian homeowners is too low. In 2018, EEIMs have been implemented in 4,000 houses. This number represents only 4% of the government's target which is the implementation of EEIMs in 100,000 houses per year. The present article, accordingly, attempts to explore the barriers to the adoption of EEIMs. To this effect, a questionnaire survey with 150 randomly selected Algerian single-family homeowners in Mostaganem area was used for the study. It was found that the five greatest barriers to the adoption of EEIMs were: (1) the lack of subsidies and rebates on energy efficient equipment, (2) the high initial prices of energy efficient equipment, (3) the lack of techniques and tools for the estimation of saved energy, (4) the unwillingness to borrow money and (5) the difficulty of identifying, procuring, installing, operating and maintaining energy efficiency measures. The principal component analysis categorised 16 barriers around four components: (1) "Financial" barriers, (2) "Technological" barriers, (3) "Lack of time and knowledge" barriers and (4) "Attitude towards energy efficiency improvements" barriers. Finally, the multivariate analysis of variance (MANOVA) analysis has shown that the perception of barriers to the adoption of EEIMs also differs in accordance with certain personal characteristics of the homeowner.

Finally, the multivariate analysis of variance (MANOVA) analysis has shown that the perception of barriers to the adoption of EEIMs also differs in accordance with certain personal characteristics of the homeowner.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"33 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2020-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87209183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fundamental rights of equity and justice call for a balance in the identity of both males and females in every sector. In spite of several strategies aimed at increasing women engagement, the female identity is still blurred in the construction workplace scenery. The study evaluated measures to balancing the female identity in the construction industry. The dataset was obtained through a questionnaire instrument of 105 women in the construction industry. The data were presented using stacked bars, cross tabulation/mean score, principal component analysis (PCA) and one-way analysis of variance (ANOVA). The study revealed that anti-feminine characteristics exist in the industry in form of work growth gap, position/pay gap and symbolic intimidation. The study showed that there is the need for attitudinal changes in the bullying culture and the sexual orientation towards co-workers. Strategies to balance the female identity can be achieved at the national level, construction organisation level, union level and client level. In conclusion, the female identity can be balanced in the construction industry by encouraging adequately funded female mentors/role model programmes. The study recommended that beyond legislation, the onus is on women to inspire women. In order to attract, retain women and reduce the anti-feminine characteristics in the construction sector, there is a need for female mentors/role models to be actively engaged. Strategies and approaches that can alter a female-biased attitude need to be engaged in the minds of construction professionals.
