Sustainable construction management: A systematic review of the literature with meta-analysis

The development of the construction industry in Indonesia has been substantially contributing to the enhancement of the social and economic development of the people. However, its expansion has also become an issue, as the development might be implicated in the abuse of environmental sustainability when the practices of conducting the construction project abandon the rules and regulations of sustainable green construction concepts. Therefore, this study attempted to introduce a quantitative assessment tool called the Green Construction Site Index (GCSI) to evaluate the performance of an ongoing project to meet the sustainable green construction concept. The aim of this study was to investigate the effectiveness of GCSI as a quantitative assessment tool to measure the implementation of the green construction concept conducted by ongoing projects. Data were collected by onsite direct observation, interviews with key personnel, and project documentation review. Data were organized and analyzed using descriptive elaboration. The results showed that three aspects, the Efficiency Index (IE), Productivity Index (IP), and Awareness Index (IA), were effective in assessing 10 ongoing construction projects, categorized as Non-Commercial Non-Residential Building, Commercial Residential Building, and Commercial Non-Residential Building. The index generated using GCSI, upon assessing 10 buildings, was 3.39 and fell into the Good category with IE = 3.51, IP = of 2.86, and IA = 3.84. Another finding shows that the Project Organizational Commitment Index (POCI) to the indicator of the GCSI was 3.31 (Good category) with IPOL = 3.36, IPRO = 3.49, and IPRAC = 2.75. The capability of the GCSI to identify three aspects within a construction project simultaneously and comprehensively suggests the importance of its function as an effective tool that gives benefits to not only the contactors, but also to the authorities that control the green construction-related performance. Therefore, the GCSI is expected to be applied as a standardized reference by both the construction industries and regulating authorities. Despite its satisfactory findings, the GCSI needs to be furthered to achieve its reliability and validity to be adopted internationally.

An effective communication process is an important element in distributing information to various project teams. The previous study demonstrates the importance of communication in the project management process in order to encourage project delivery processes successfully. Unfortunately, the issue of communication still dominates Industrialization Building System (IBS) because the project development process are still based on traditional methods. This research aims to explore the cause of communication challenges between construction players in managing IBS projects. The research methodology implemented for this paper was a semi-structured interview approach used to investigate the communication problem. Five experienced project managers were chosen from across the industry. The findings of this study are valuable for improving the communication level of project teams, which will indirectly increase the level of the IBS project delivery process and strengthen team integration on IBS projects in Malaysia.

A cause of communication failure in managing industrialized building system (IBS) projects : a perspective view from project managers

. The population increase until the end of 2019 reached 267 million. This is in line with developments that support activities. This is inseparable from the actions of one of the precast concrete companies PT.WB Precast Plant Karawang in supporting development that produces waste in the form of wastewater. The parameter measured as a reference in carrying out processing is the Minister of Health Regulation Number 32 of 2017. This study's method refers to turbidity as a physical parameter, namely 25NTU and hardness total as a chemical parameter, which is 500 mg / l. CaCO3. Objectives: The purpose of this study was to determine the optimization of the use of PAC as a coagulant and flocculant to reduce the turbidity and total hardness and determine the optimum detention time of flocculation. Method and results: The sampling method in this study is observation. The population in this study is concrete wastewater with parameter values that are not in accordance with the standard.  Conclusion: By using PAC 10% the optimum doses is 140 ppm, and the optimum detention time of flocculation is 5 minute that can reduce the turbidity from 275 NTU to be 11.615 NTU or 95.7% and can reduce total hardness from 948.75 mg/l CaCO3 to be 491.25 mg/l CaCO3 or 48.2%.

Optimization of Coagulation and Flocculation in Concrete Wastewater of Precast Industry

The construction industry plays an important role in establishing the infrastructure required for socio-economic development and directly contributes to economic growth. On the other side, it also generates severe impacts on the environment. The construction industry is one of the biggest environmental polluters and it also consumes large quantities of raw materials. Value Engineering originates from the manufacturing industry in order to deliver higher value and quality to a product by means of an increase in efficiency. ‘Lean Construction’ (LC) concepts emerged as a consequence of the application of VE philosophy, specifically for construction industry. LC extends from the objectives of a lean production system – to maximize value and to minimize waste – in relation to specific techniques and then applies them conceptually in a new project delivery process. The aims of this paper are to present practical examples of the application of Value Engineering and Lean Construction concepts within a green building construction project and to qualitatively assess its benefits in terms of environmental impact and waste minimization. A detailed case study was conducted for project execution of a new multi-storey government institutional building in the Jakarta central business district. This project adopts a Green Building and a Green Site concept in order to reduce potential environmental impact during the construction phase itself and during the occupancy phase of the building. The case study primarily concerns issues such as water consumption, power usage, etc. This project is a perfect example for the application of Value Engineering and Lean Construction philosophies in order to deliver better quality, faster completion, environmentally friendly practice, and less waste generation. The adoption of environmental awareness in the context of building design, the application of alternative and/or recycled/environmentally friendly materials, along with a number of “green” technologies and building systems featured in this building concept will deliver greater value without jeopardizing the ecology. Meanwhile, the adoption of prefabrication construction methods, intelligent excavation works, ‘Reduce- Reuse-Recycle’ principles, and simple ‘environmentally-aware’ on-site practices can minimize the waste produced and the local environmental impact emitted during project execution.

Improving project performance and waste reduction in construction projects: A case study of a government institutional building project

Construction industry plays an important role in establishing the infrastructure required for socio-economic development and directly contribute to economic growth. Construction industry is associated with high energy consumption, resource depletion, and large amount of waste generation. Environmental impact assessments are necessary in order to identify effective measures in mitigating impacts associated with construction activities. Associated impacts must be quantitatively measured in order to determine the current status and thus, this shall help to gain more understanding in identifying mitigation actions. Assessment tools for evaluating the sustainability of construction during operational stage are crucial. "Green Construction" is construction projects which demonstrate the required sustainability level. Green construction involves a number of environmental and sustainability aspects. The aims of this paper are to present a practical case study of Green Construction project execution and to qualitatively evaluate its features based on "green" aspects and environmental impacts criteria. The importance of this research is to revolutionize and modernize the construction into a more sustainable and industry by the implementation of "green" technologies, evaluation and monitoring tools, and adaptation of up-to-date international codes, standards, and policies. Detailed case study based on green construction aspects was conducted during project execution phases of a new multi-storey government institutional building in the Jakarta central business district. This project adopts Green Building and Green Site concepts in order to reduce potential environmental impact during the construction phase. In overall, this project has demonstrated most of green construction aspects. Prefabrication construction system, i.e. precast concrete elements and steel formwork system are proven to significantly reduce the waste generated from concreting activities. Moreover, adaptation of relevant HSE international code & standards, audit and monitoring of environmental performance, support from top management, as well as awareness of environmental and social impacts are among many factors that contribute to implementation of green construction.
