Abstract

Increasing the mobility of the working class in urban areas will increase their productivity, which in turn will increase the economic output of the region. This can be achieved by providing a means of mass transportation infrastructure that is fast, affordable, and efficient i.e. rail-based mass transportation. However, the Ministry of National Development Planning estimated there is an infrastructure-funding gap of 4,321 trillion rupiahs to achieve Indonesia's development targets. Inviting the private sector to participate in infrastructure development investment in Land Value Capture (LVC) scheme becomes one of the solutions that need to be studied further. LVC is considered a promising infrastructure financing scheme for the private sector’s investment. However, one of the challenges faced by the government in the application is to identify feasible instruments to capture the value of the land. This study aims to find LVC instruments that are feasible from the perspective of the Indonesian government agency. In-depth interviews with experts from government agencies were conducted to explore the possibilities of LVC instruments that can be applied in Indonesia for mass transportation infrastructure development in urban areas. The result shows that most of the Key Informants (KIs) agree that density bonuses and joint development instruments are applicable LVC schemes for Indonesia. It can be concluded from the analysis that these instruments are better prepared due to the availability of regulations that are mutually beneficial for both the government and the private sector, and has a simpler bureaucratic process.

Abstract

High-rise building projects expose a high risk due to structural design complexity, large workloads, and long project duration. The complexity of the work includes the design of Mechanical, Electrical, Plumbing (MEP), HVAC (Heating, Ventilation and Air Conditioning) systems, early warning, watering systems, hydrants, sprinklers, evacuation routes in the form of emergency stairs and fire doors. This research focuses on the application of BIM 5D to estimate and improve the cost performance of MEP work in high-rise hotel buildings. This research combines qualitative and quantitative approaches through in-depth interviews and BIM 5D modelling to achieve the research objective. The results showed influential factors for BIM implementation namely 2D Drawings, BIM 5D implementation, specification and technical plan, operator experiences, BIM 5D models, individual selection model, estimating, calculation process, cost database, and operator education. The findings of this research also show a cost efficiency of 3.56% from the BIM 5D implementation to the high-rise hotel building.

Abstract

Organisational culture characterisation is indispensable for aspiring organisations that want to measure up with the contemporary business trend in terms of performance. This paper aims to determine the organisational culture characterisation of construction firms in Nigeria to improve the organisational culture power to drive organisational performance of the firms. Thus the objectives are to enumerate the factors that contribute to the organisational culture capability and to determine the organisational culture characterisation of construction firms in Nigeria. A quantitative method was adopted for this research in which 113 questionnaires from a sample size of 254 disseminated informed by purposive random sampling technique, were used to draw the data from the respondents who are predominantly construction workers. The analysis of the data was done using factor analysis, k-mean analysis, and a one-way ANOVA. The results reveal that there is the presence of three distinct organisational culture clusters in the construction firms in Nigeria. The results also disclosed that family and work policy should be inculcated into the organisational culture and held in regard if performance is inevitable. The study concluded that organisational culture is a vital aspect of construction firms and each firm should improve on their culture to better their organisational performances. It is recommended that family and work policy should be given preference in the organisation, also supervisors should be trained in relevant skills that will aid their commitment to their workforce diversity.

Abstract

The reuse of material from collapsed building debris as a natural aggregate substituent has been an alternative to solve concrete waste in Indonesia. However, its use in larger structures needs further research. The objectives of this research are to study the concrete homogeneity at a certain sample height and to find the strength prediction of Recycled Aggregate Concrete (RAC). In the previous laboratory study, the obtained concrete compressive strength with 20% RAC substitution (from the concrete ruins with fc’ = 30 MPa) was 27-30 MPa. Since, RAC contains natural aggregates and mixed cement paste, it is important to research the distribution, homogeneity and strength prediction of the concrete. The measurement was done using a non-destructive instrument called Ultrasonic Pulse Velocity (UPV). This paper presents a series of experiments investigating homogeneity and predicting compressive strength using both Destructive and Non-Destructive Tests (NDT). To do so, three steps in the experimental works were done. Firstly, UPV propagation measurements at four different levels through vertical prismatic beam specimens was performed. Two transducers were used in the direct mode of transmission with a 15 cm distance of measurement. Secondly, identical concrete samples cast in cubic form were measured using UPV and tested under compression. Thirdly, the core-drilled samples were taken from the vertical prismatic beam specimens for further investigation. The wave propagation velocity through RAC and the concrete compressive strength relationship demonstrate similar pattern as concrete with GFC (Gypsum-free-cement) performed by Brozovsky. This pulse velocity-concrete strength relationship can be used to predict the strength of RAC. Both the prediction curve and the homogeneity properties can be useful when casting a larger element of structures using RAC

Abstract

Asia and the Pacific region is a hot spot for water insecurity in the world. With water resources such as ground and surface water depleting, the demand for water consumption increases as urban population continues to grow. Meanwhile, non-revenue water (NRW) leads to inefficient water service delivery, waste of energy, drinking water contamination, loss of revenue, and increased operation costs. As the water stress continues in the region, what can cities in the region do to sustain their water future? To answer this question, this paper uses Singapore as an example and draws lessons from its urban water management experience. It finds that countries can take away from Singapore knowledge and practices, including institution autonomy paired with people-centric management, inter-agency coordination, emphasis on demand management, non-revenue water (NRW) regulation, as well as technologies and innovations. Apart from these, this paper also finds that the remaining water challenges faced by Singapore, such as climate change, energy dependence, and financial sustainability, are also shared by cities in developing Asia and Pacific countries. This paper therefore proposes solutions such as diversifying water sources and reducing NRW, increasing energy efficiency and exploring renewable energy, as well as engaging private sector investment as some of the first steps in tackling those shared challenges.

Abstract

In the construction industry, public-private partnership (PPP) has been becoming increasingly common. While real-world PPP for infrastructure projects have been reported in many journals, published work on systematically summarizing what they have already provided remains limited. Based on the 1749 publications on PPP for infrastructure collected from the Scopus database for the period of 2000-2020, this study conducted a scientometric analysis in terms of annual publications, regional distribution, active contributors, published journals, co-occurrence keywords, and main research themes of previous studies. This paper found that there was a significant increase in the number of publications on PPP for infrastructure since 2008. Researchers from the USA, China, and Australia have been the main contributors to this research area. In addition, four main themes of research on PPP for infrastructure are explored, and several research gaps and research directions in this area are established for further studies.

Abstract

In March and December 2018, the Indian government auctioned two bundles of roads to monetize its assets using the Toll-Operate-Transfer (TOT) model. This paper focuses on understanding spatial distribution of monetized road assets for TOT I and II. Our hypothesis is that there are likely to be strategic reasons for the spatial distribution. The research design consists of comparative case studies of these two auctions. The data sources include in-depth interviews with bidders, government officials, and analysts as well as documentary analyses of concession agreements, bid documents, and other secondary data. It is found that road assets for TOT I were in “politically friendly” states with better asset quality to make them bankable and encourage private participation in future auctions. The bids were well above the reserve price. For TOT II, the assets were of lower quality and three highways out of eight in the auction bundle were in left-leaning opposition-controlled states. The reserve price was also higher, and unfortunately, the bids were too low, and the contract was not awarded.

Abstract

Waste plastic materials are typical wastes of interest to researchers and are arguably the most common forms of waste, especially in African cities. The reuse of plastic waste in concrete matrices has the potentials to contribute to the development of sustainable concrete likely to conserve resources and prevent pollution. However, the inclusion of plastics in concrete has been reported to have a negative impact on its compressive strength behaviour. This research is aimed at ameliorating this negative impact through pulverisation and chemical treatment of High-Density Polyethylene (HDPE) before its use as an admixture for concrete production. Concretes of Grades M25 and M50 were prepared using (150 x150 x 150) mm steel moulds, adopting the BRE mix design method. The concrete mix was modified with pulverised High-Density Polyethylene (HDPE) treated with 20% hydrogen peroxide at (0, 0.25, 0.5, 0.75, and 1%) by weight of cement. Hydroplast-500, a superplasticizer was used throughout the study in order of 1000litres/50kg by weight of cement. A constant water/cement ratio of 0.4 and 0.36 was adopted for requisite workability for Grades M25 and M50 concretes respectively. After 7, 28, and 90 days of curing in water, the concrete cubes were dried and tested for their compressive strengths. Results obtained showed that at HDPE content beyond 0.5%, restrained hydration takes negative effects on the concrete. It was also shown that the designed compressive strengths of the tested samples were satisfactorily met in all cases indicating improvement in the compressive behaviour of the samples. Based on the findings of this study, it was recommended that treated pulverised HDPE could be used as an admixture in concretes without compromising their compressive strengths.

Abstract

Infrastructure development plays a crucial role in accelerating the sustainable economic growth and development of a country. The increased provision of public infrastructure can help raise the GDP growth level by lowering production costs, enlarging markets, raising total factor productivity,and facilitating economic activities. Furthermore, infrastructure helps improve the living standards of the people by providing jobs and building the local suppliers' and developers’ capabilities, which contribute to reducing poverty and improving development outcomes. On the other hand, infrastructure is also crucial and lies at the core of efforts to achieve sustainable development. It encompasses many aspects of the Sustainable Development Goals (SDGs), such as health, education, access to energy, as well as clean water and sanitation. The infrastructure improvement is implied in most of the targets of SDGs. The importance of infrastructure must take the sustainable development dimension into account; hence greater efficiencies can be obtained to achieve SDGs successfully. Despite its potential benefits, infrastructure development that is poorly planned, implemented, or operated brings negative consequences for the society, which is escalated by an overrun budget and ineffective usage. Therefore, an infrastructure system must be developed to meet sustainability needs. Sustainability in infrastructure can be comprehended as how the attributes of the practices, products, services, and resources used in the infrastructure development can contribute to the continuation of ecosystem components and functions for generations in the future. Infrastructure projects must deliver better value by going hand-in-hand with sustainability, projecting its benefits and costs towards both the short-term goals and long-term implications. In order to be aligned with the dimension of sustainability, infrastructure needs to consider the economic, social, and environmental aspects. In terms of the economic aspect, infrastructure development should contribute to overall growth by supporting inclusivity, boosting productivity, and delivering accessible and affordable services. In terms of the social aspect, infrastructure is supposed to improve livelihoods, enhance human well-being, and remove poverty in all forms. Lastly, in terms of environmental aspects, the development of infrastructure should preserve the natural environment, ecosystems, and the biodiversity within by supporting the use of high-energy efficiency standards and promoting the resource-efficient approach contributing to reducing overall carbon emissions during its lifecycle. As sustainable infrastructure becomes a cornerstone to achieving the SDGs; therefore, the long-term vision for developing a national infrastructure system informed by SDGs should be ensured. We argue that these visions can be delivered by establishing adaptable plans that include implementing low-carbon solutions and resource-efficient, ecologically based, and energy-efficient technologies.

Abstract

‘Desakota’ has been acknowledged as a unique landscape condition in South East Asia and Indonesia especially. In the middle of emerging economies and rapid urban development, ‘desakota’ as a peri-urban area suffers environmental degradation in the economy and socio-culture because of poor planning and control from state and local authority. Inequality, spatial segregation, and inadequate infrastructure or slums are issues that peri-urban’desakota’ has to encounter. Nevertheless, as a tool for producing and adapting the built environment and introducing a spatial order, urban design shows less concern for developing this distinct peri-urban area. This study conducted in Teluknaga, Tangerang, the neighboring Jakarta, examined the significance of informality which shapes a compact urban form in the 'desakota' area. Data collection of the study was done through field study by conducting interviews, observations, and direct mapping. We conclude that the informality potents should be considered for designing ‘desakota’ to maintain its compact form and create a more sustainable urban form and a better urban life.
