Abstract

Currently, the Indonesian government continues to encourage the realization of sustainable development. The green concept is a sustainable development trend in the construction material industry. The concrete industry plays a vital role as a supplier of concrete materials in construction, so its availability is essential. The role of concrete industry itself has a negative impact on the environment. Stakeholders increase the cost of green retrofitting so that the industry or building becomes eco-friendly. The research method was carried out using a process case study, namely, how to implement green retrofitting cost performance in the concrete industry using Value Engineering and Life Cycle Cost Analysis. Theoretically, the research results provide additional knowledge for academics; practitioners can provide problem-solving to get an overview of the implementation of the green concept in the industry regarding the flow of implementation and the benefits of savings in an environmentally friendly production process. The application of value engineering in the green retrofitting of the concrete industry has increased the cost performance of green retrofitting by 8.66% with a return of 3 years and 8 months and increased the functions and benefits of an eco-friendly and sustainable concrete industry

Abstract

As a result of climate change poses a threat and crisis that is currently sweeping the world; one of them is causing drought, rising sea levels, melting polar ice, and heat waves; therefore, the target towards Net Zero Emission (NZE) in 2060 must be an obligation in all countries. Green Building (GB) is a building that meets Building Technical Standards, and It has demonstrated demonstrable success in conserving resources such as water, energy, and other resources. The application of GB principles following the function and classification in every stage of its implementation is expected to reduce greenhouse gas emissions. This research aims to analyze the cost of improvement work based on GB assessment, which is an influencing factor in applying the regulation from the Minister of Public Works and Public Housing (PUPR) Indonesian government. The Technical Guidelines for GB, through the Minister of PUPR No.1 of 2022, is the latest regulation in Indonesia. Blockchain- Building Information Modelling (BIM) and the Implementation of GB using Structural Equation Modelling–Partial Least Square (SEM-PLS) for the analysis. Applying Blockchain-BIM to overcome the cost constraints is proven to increase the cost performance of GB in modern shopping center buildings by 3 - 3.8% in the Basic rating. It is higher when selecting a zero-emission approach for other ratings, dramatically affecting the required green costs.

Abstract

High-rise building projects expose a high risk due to structural design complexity, large workloads, and long project duration. The complexity of the work includes the design of Mechanical, Electrical, Plumbing (MEP), HVAC (Heating, Ventilation and Air Conditioning) systems, early warning, watering systems, hydrants, sprinklers, evacuation routes in the form of emergency stairs and fire doors. This research focuses on the application of BIM 5D to estimate and improve the cost performance of MEP work in high-rise hotel buildings. This research combines qualitative and quantitative approaches through in-depth interviews and BIM 5D modelling to achieve the research objective. The results showed influential factors for BIM implementation namely 2D Drawings, BIM 5D implementation, specification and technical plan, operator experiences, BIM 5D models, individual selection model, estimating, calculation process, cost database, and operator education. The findings of this research also show a cost efficiency of 3.56% from the BIM 5D implementation to the high-rise hotel building.
