Abstract

Environmental, economic, and social factors are three critical dimensions that influence sustainable construction. Nevertheless, stakeholders in the construction sector remain insufficiently cognizant of the social dimension of sustainability. This study aims to elucidate the elements associated with the social dimension of sustainability and to identify factors deemed significant by stakeholders in the construction industry. This study employed a quantitative research methodology. A questionnaire was developed based on a review of pertinent literature and formed using a Likert scale. The questionnaire was subsequently sent to stakeholders in the construction industry, and the findings were evaluated utilizing the Relative Importance Index (RII). The findings indicate that three critical variables in social sustainability pertain to internal project stakeholders: workplace safety and health, stakeholder interaction, and worker training and education. These three elements are the essential components of social sustainability. Factors related to external stakeholders, such as the community around the project site, remain a secondary concern for construction industry players today.

Abstract

Introduction: The construction industry is widely recognized as one of the sectors with significant mental health challenges. Many studies revealed that mental health problems such as depression, burnout, and sleep difficulty are more common in the construction industry compared to other industries. The causes may include high risk environment, long working hours, job insecurity, and machoism culture. On the other hand, the issue of mental health in the Indonesian construction sector is still not widely understood. Hence, this study investigates the key context-specific factors that influence the mental health of construction workers. Method: A mixed-method approach was employed, consisting of an integrative literature review (ILR) and exploratory factor analysis (EFA). The ILR identified twenty-three context-specific mental health factors, subsequently used as input in the questionnaire survey. The questionnaire consists of demographic characteristics and measurement of mental health factors using a six-point Likert scale. The survey was distributed to construction workers in Indonesia, each with a minimum of two years of work experience. The collected data were analyzed using EFA. Result: This study found five key groups of context-specific factors: workplace, work pressure, role, gender inequality, and psychosocial factors. These factors are found to be deeply interconnected, often exacerbating one another. The study underscores the complexity of mental health issues in this high-pressure, high-risk industry. The results suggest that addressing these challenges requires a multifaceted approach to better understand and alleviate the stress experienced by construction workers. Conclusion: This study presents five mental health determinants among construction workers in Indonesia. The findings can form the basis for further research and the formulation of work policies that are more responsive to local conditions.

Abstract

The execution of construction projects involves many parties, one of which is subcontractors. In general, subcontractors can be divided into three types, namely domestic subcontractors, nominated subcontractors, and named subcontractors. Many studies have been carried out regarding the first two types of subcontractors, but studies related to named subcontractors are scarce. In contrast to nominated subcontractors, named subcontractors are selected by the main contractor based on a list of subcontractor names provided by the employer. This research aims to identify the criteria in selecting named subcontractors by the main contractor. This research applies a qualitative method approach with integrative literature review and interview techniques. The results show the company's experience, financial capabilities, technical capabilities, resource factors, and offer price factors as important selection criteria. This research contributes to the body of knowledge considering that there are still few studies on named subcontractors, especially regarding its selection criteria by the main contractor.

Abstract

QTO (Quantity Take Off) is a measurement for calculating the volume of the entire building in detail. QTO calculation has 2 (two) methods, namely the manual calculation method using the SMPI (Standard Metode Pengukuran Indonesia) and the digital calculation method using BIM (Building Information Modeling). The BIM that used in the calculation of this research is Autodesk Revit. Both methods have their respective advantages, disadvantages, and have the potential to produce different volume calculation results. Therefore, both methods are used in this research and the results has been compared. The results of the total volume be written into a construction document called the BQ (Bill of Quantity). BQ generate calculations from both BIM (Revit) and manual calculations (SMPI). Difference in calculation results between manual calculation (SMPI) and BIM (Revit) calculation for rebar is 0,49%; concrete is 0,14%; while formwork is 0,07%. This indicates that the manual calculation method and the BIM calculation method (Revit) provide approximately same and accurate results. The largest difference in volume calculation results is found in the calculation of rebar due to inaccuracies of 3D modeling carried out by engineers. 3D modeling on Revit software requires special skill for precision, accuracy, and expertise, as the potential for 3D modeling errors is very high.
