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

Water quality modeling is highly needed to predict and to identify the water quality alteration and distribution along the water body. Besides that, water quality modeling also can be used to predict the pollutant load if there is no data recording. The water quality analysis simulation program (WASP), will be used in this study to forecast domestic load, in particular BOD and TP loads in Duriangkang Dam. Initially, the estimated load is obtained based on the previous study that being extended by using a linear regression line. After that, the estimated load is calibrated according to the results of the water test. The WASP model is simulated for a period of 3 years from 1 January 2016 to 31 December 2018 and is divided into 2 processes, namely calibration and verification process. The calibration process is carried out in the first two years, followed by the verification process for the remainder of the year. The calibration and verification process are measured by objective functions, namely RMSE and the percentage difference. According to the simulation results, the objective functions provide satisfying findings, which means that the predicted BOD and TP loads for Duriangkang Dam during that time are accurate.

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

Despite the socio-economic importance of the Built Environment (BE) industry; its resources and products regrettably impact the host environment negatively, necessitating a departure from traditional to Sustainable Construction (SC) methods. Lack of SC awareness has been identified by several researchers as a major impediment to its adoption in Nigeria. This study, therefore, assessed the level of SC awareness, examined the sources of SC knowledge, and determined ways of improving SC applicability in Nigeria. The descriptive survey research methodology was used and a structured questionnaire administered purposively to 171 BE professionals, with  133 valid responses, hence a 78% success rate. The results of the study showed that all the states in the six geo-political zones fell below the geopolitical zone mean awareness index (GZMAi) value of 0.700; a poor contribution of current academic curriculum, and poor site experience arising from paucity of SC knowledge on projects, as hindrances to its applicability. The study concludes that the characteristic low knowledge level of SC amongst BE professionals are institutionally based, and therefore, recommends adoption of global sustainability standards, increased sensitization of SC techniques via seminars and training workshops, the inclusion of SC in tertiary education curriculum, and in the certification programmes of BE professional institutions, amongst others

Abstract

The complex networks of activities of construction projects have made the construction environment unfriendly and unsafe for the construction tradespeople. Tradespeople play a key role in construction project delivery and are the major victims of accidents that affect negatively on project performance. This study assessed the perception of construction tradespeople on the health and safety management on the construction site. The study objectives are; to determine the trade with the highest accident exposure level, to ascertain the types of accidents and level of occurrence, to determine the major causes of accidents on construction sites, and to examine the possible measures for preventing accidents on construction sites. A well-structured questionnaire and stratified purposive sampling technique were adopted in gathering data from the participants in Abuja, Nigeria. With a reliability index of at least 0.80, the gathered data were analysed using frequencies, percentiles, mean analytics, Kruskal-Wallis test, and Mann-Whitney U tests. The study found that Concreters/Mason/Bricklayers, Carpenters, and Steel benders/fixers/welders are the most vulnerable trades groups to hazards and accidents on construction sites. Fall-related, Slip and trip, and contact with objects (struck by objects) are the most occurring accident types. The most critical causes of accidents based on tradespeople perception are; inadequate training, drugs and alcohol, horseplay by workers, excessive working hours resulting in mental fatigue, and communication issues. The most important measures for preventing accidents on construction sites are; rewards and penalties for defaulters, the use of personal protective equipment, effective communication system on-site, correct placement of ladder through proper supervision, and site discipline among workers. The study concludes that there is a low level of implementation of health and safety management practices on construction projects site by construction organisations. Rewards for safety compliances and penalties for HS deviant workers should be put in place by the management of construction sites.

Abstract

Universitas Gadjah Mada (UGM) in Indonesia brings thousands of new students annually. This greatly affects the use of transportation modes and the need for modes of transportation to the campus. This study aims to determine the modes of transportation used by students to campus, factors that influence the choice of transportation modes, and the needs of student transportation modes. This study uses a quantitative approach with descriptive analysis and Cramer's V correlation test. The results of the study show that the transportation modes used by Universitas Gadjah Mada’s students as a means of transportation to the campus are mostly private (70.5%). Factors that influence the choice of modes of transportation are private vehicle ownership, driving license ownership, monthly allowance, residence, frequency of use of transportation modes, time of movement, distance traveled, transportation modes changing, travel time, transportation costs, security/safety, timeliness, and speed. The modes of transportation needed by students are motorbikes and online transportation/ride-hailing service. The transportation characteristics that are most needed by students are fast, cheap, and comfortable. As many as 89.4% of students agreed and as many as 10.6% of students did not agree if there were vehicles provided by the campus.

Abstract

The dynamics in technological advancement and innovations in construction methods have caused construction organizations to operate in a highly competitive environment. As knowledge is an essential asset for surviving and remaining competitive in the construction industry, this study investigates the impact of knowledge management practices on the survival and sustenance of construction organizations. Construction professionals in Abuja-Nigeria were sampled using a well-structured questionnaire and multi-sampling techniques. The results of the study show that there is a low level of implementation of Knowledge Management among the construction organizations. Furthermore, it is found that the significant benefits of KM implementation are to improve the firm's competitive position, risks reduction, and better collaboration, to encourage innovation and profitability, faster problem solving, to improve project pricing, and to improve client satisfaction and patronage. It can be concluded that KM is a tactical and strategic competitive tool for surviving high competition in the construction industry. To ensure knowledge exchange between the locals and expatriates, the government should make a 'knowledge management plan' an essential part of the contract documents for pre-qualification and selection criteria.

Abstract

COVID-19 outbreak has contributed a negative effect on the infrastructure sector worldwide. Infrastructure projects need to shut down and put on hold for an unspecified time, as this sector required a high number of workers prone to the virus transmissions. However, the degree of slowdown between countries varies and depends on the severity of pandemic and lockdown conditions. Many countries are having a slowdown in economic growth. This condition has greatly affected the supply and demand sides, making it difficult to predict recovery timelines of on-going and future project development.In response to the COVID-19 pandemic, many governments worldwide launched stimulus plans to recover their economies. The severe impacts of the outbreak need to be addressed through international cooperation. During the pandemic and recession, government expenditure is crucial to driving the economy. Infrastructure projects have been argued as a way to accelerate economic recovery, considering the infrastructure industry is absorbing many workers and driving other supply chain industrial sectors. Therefore, green investment in renewable energy, clean transportation, advanced technologies, and other low-carbon infrastructure projects can stimulate the economy during pandemics and recession.Despite playing a pivotal role in coping with current challenges, not all countries have financial freedom and supporting policies enabling them to invest in infrastructure heavily. Therefore, these countries must prioritize projects that significantly boost income per capita, livelihood improvement, and employment opportunities, particularly for mid to lower-income households. The government is encouraged to pursue the construction of social infrastructures such as healthcare, education, public facilities, and transportation. This attempt is expected to facilitate quick recovery from the pandemic and maintain public services.Most stakeholders associated with the infrastructure sector that suffered from the crisis attempted to create a roadmap, quick wins, and strategic actions to prepare challenges they might face for the next normal. Related stakeholders are highly encouraged to consider digital technology adoption, supply chain redistribution of products and materials, resource allocation of company assets and portfolio, organization restructuring, identification of alternative market opportunities, and collaboration with other parties, including the government, to rebuild the industry. These actions aim to maintain businesses from a growing debt and high-cost recovery during the pandemic.Remote working has catapulted the need to utilize technology further to accelerate infrastructure development and gain maximum benefits for participated stakeholders. The fourth Industrial Revolution (Industry 4.0) enables automation and data exchange within a cyber-system. Digital transformation through big data, machine learning, cloud computing, and other artificial intelligence domain has facilitated real-time working condition between office and site. Advanced technologies also offer a vast potential to improve project performance and increase construction workers' productivity compared to the business as usual approach. We believe that the pandemic urged the utilization of a robust technological innovation in developing infrastructure projects in the post-pandemic era.

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.
