Housing Shortages

The increasing demands for housing the burgeoning urban population in developing countries like India has impelled the need to shift to mechanised construction practices like Precast Concrete Construction (PCCon) for faster supply of projects. PCCon has been successfully implemented in developed countries to meet the once prevalent housing shortages and is still being adopted extensively in high rise residential building projects in these countries. PCCon offers several benefits compared to cast in situ construction practices such as reduced construction time, time and cost certainty, improved quality control and improved health and safety. PCCon also promotes environment friendly construction, addresses shortage of skills and results in minimisation of life cycle costs.

Line Of Balance

The finish work on high-rise residential buildings is performed simultaneously with mechanical and electrical construction work, which results in frequent work interference and delay. This significantly hinders efficient schedule management. Critical Path Method (CPM) is inefficient when applied to high-rise residential building projects in which work is repeatedly carried out for each floor. Line-of-Balance (LOB) is widely used for its effectiveness in managing repetitive work. LOB was developed into TACT and eTACT (enhanced-TACT) to combine heterogeneous works con­tinuously. In particular, the eTACT schedule management method has an advantage in that it is capable of systemati­cally connecting detailed construction, mechanical and electrical construction projects using a work planning template. This study evaluates the time reduction effect of the eTACT method for a high-rise residential building. A comparative analysis of data on 102 cases of non-applied projects and 44 cases of projects using the eTACT method over a period of 10 years is presented to verify its effectiveness. The result shows that finish work time was reduced by 25% or about 53 days on average.

Qualitative Approaches

The building industry contributed an impressive share in Pakistan's growth sector, where the construction industry contributes almost 2.74% of the GDP of Pakistan. In most metropolitan cities, the trend of building multi-story structures is at increase. However, this construction industry is a prominent accident-prone industry where laborers generally work in an unsafe environment. These projects suffer from fatal and non-fatal accidents as labor health and security are not a prime aim in the construction industry despite all employees still dealing with safety issues. This research examines the Occupational safety and health (OSH) performance in High-rise building projects in Pakistan. This review focuses on adopting qualitative approaches, using the comprehensive literature approach for seeking current practice in health and safety and OHS laws in Pakistan's building industry. Finally, it proposes a realistic strategy for developing a safe environment at workplaces. Research indicates that Pakistan's construction sector should consider workers' safety as a priority, update and enforce safety laws at the workplace to enrich OHS conditions in the Pakistani construction sector.

Analysis Technique

Abstract The purpose of this study is to analyze the effect of proactive and reactive performance on indicators of the application of OHS in high-rise building construction. The data used in this study were obtained from a questionnaire (primary) and several observations and direct interviews with employees in 20 types of high-rise building projects in Indonesia. The analysis technique used is multiple regression analysis using hypothesis testing, namely the F test and t test. The results showed that simultaneously and partially the independent variables consisting of proactive performance (X1) and reactive performance (X2) had a significant effect on the variable construction K3 program (Y). From the ANOVA or F test, a significant number (Sig) (0.037) is obtained which is below 0.05 and the Fcount is 11.570 where the F count is greater than F table, F table is 3.84. These results indicate that the regression model is feasible to be used to predict the proactive performance and reactive performance variables together to influence the performance of the OHS culture of high-rise building construction. Seeing the performance points of construction project employees can be influenced by many other points from the results of the T Test calculation where the competence of workers obtains T results of 3.098 or the highest among others so that with this we can say that worker competence is a critical factor in improving cultural performance.

Modular Buildings

Off-site construction has been increasingly employed due to its advantages, for instance, improved quality control, reduced skills labour, faster construction time, decreased material wastage and safe working environment. As the most cutting-edge off-site construction, modular buildings have been utilised for residential building, student accommodation, and hotel projects. However, because of existing and underlying constraints, the adoption of modular buildings is still relatively low. To reveal factors hindering the development of high-rise modular buildings, a comprehensive literature review, coupled with a focus group study, were conducted. A questionnaire survey inquiring about all stakeholders was implemented to quantify constraints. The results were further examined according to a real-life case study. This paper manifested that “Lack of coordination and communication among stakeholders”, “Higher cost”, “Lack of government support”, “Lack of experience and expertise”, “Lack of building codes and standards”, “Poor supply chain integration”, and “Complexity of connection” are the top barriers curbing the uptake of modular buildings. The findings should provide a valuable reference for stakeholders adopting modular buildings, whilst mitigating risks amid modular construction. Future research is expected to exploit building information modelling and design for manufacture and assembly to alleviate these existing constraints and promote the performance of modular construction as well.

Introduction. The partial replacement of cast-in-situ concrete with precast concrete in the residential construction sector allows to reduce construction time and cost, increase labour productivity and cut CO2 emissions. Combinations of prefabricated and monolithic elements in precast monolithic frames are presented; they encompass 6 different structural options of precast monolithic frames and 2 types of monolithic frames. The co-authors compare production costs and integrated labor intensity for all frame design options, construction periods per 1,000 m3 of a residential building for various structural options of the frame, and assess potential reduction in carbon dioxide emissions due to a change in the amount of precast reinforced concrete in the building frame structure. Materials and methods. The co-authors have developed a method that employs weighted average to identify the optimal type of a precast monolithic frame. The method takes account of such factors as production costs, integrated labour intensity, construction time and reduction in carbon dioxide gas emissions (in per centum) per 1,000 m3 of the frame structure. Results. The optimal structure of a precast monolithic frame was selected and calculated using weighted average. Weighted average was used to identify the most effective structural frame. The calculation results have shown that ARKOS precast monolithic frame with precast columns is the leader in terms of weighted average; it best suits the construction of a residential building. If we consider each of the selected indicators separately, RECON frame with precast floors is to be selected; however, RECON is inferior to ARKOS in terms of weighted average due to different values of the weight coefficients attached to each of the assessment criteria. Conclusions. The co-authors have proven the efficiency of precast monolithic frame systems in comparison with monolithic frames if applied to construct a residential building. The proposed method was employed to select the optimal type of frame.
