Abstract

The construction industry is a significant consumer of natural resources and a contributor to environmental issues and ecological instability. This has led to the emergence of sustainable programmes (green construction) which aim to minimise the impact of development projects. The objective of this study is to identify the critical success factor in implementing green construction and to the extent of familiarity among middle-sized companies in the province of East Java with the implementation of green construction projects and to ascertain the factors that affect the success of such projects. The case study subjects are four medium-sized construction companies in East Java that have experience in implementing green building projects. The data obtained will be analysed on mean using IBM SPSS software on each variable. The results will identify the top five critical success factors based on questionnaires distributed to respondents. The findings of critical success factors are as follows: Integrated planning and/or design, Adequate project funding sources (smooth payments), Classification/capabilities of implementing contractors, Effective communication among stakeholders, Competence and experience of the project manager, and last critical success factor is Applicable policies/regulations regarding green construction. These findings are expected that this research will contribute to a deeper understanding of the critical factors that influence success in implementing green construction projects.

Abstract

It was Optimizing resources to analyze cost efficiency in implementing construction projects. One method that can be used for resource optimization is value engineering (VE). Value engineering (VE) as a management technique to determine the efficiency between the cost and performance of a product or project and stay on appearance, quality and maintenance. Then value engineering is applied to the construction of apartment buildings to get cost efficiencies from the initial budget planning. This study aims to determine the effectiveness of value engineering in the construction of apartment buildings, especially in-wall installations. The VE method consists of five stages: Information stage, the creativity stage, the analysis stage, the development stage, and the presentation stage. Information stage, data collection in the form of cost planning, detail engineering design, work plan and terms. Based on the data obtained, the total contract value for the apartment building is Rp. 87,328,000,000. wall installation as one of the highest cost contributors. There are two alternative recommendations, namely sandwich panel walls and precast walls. The analysis found that the sandwich panel wall has the most efficient value, namely the total RAB value of 2.5% from the initial plan.
