Abstract

Construction industry in Malaysia has moved forward into technology-driven where its transition is in progress from conventional method to a more advanced and mechanized system known as the Industrialized Building System (IBS). This paper presents economic aspects of using Interlocking Hollow Brick System (IHBS) in the construction of the Primary Distribution Sub-station (PPU) of energy infrastructure asset development. The main objective is to compare the difference in construction method between IHBS with the conventional method. The study is focused on comparing various aspects of using interlocking block system in terms of time, costs, and utilization of workforce. Building Information Modelling tools in this study are used. From the analysis and modeling of the PPU, it is shown that the implementation of IHBS can reduce construction time, cost, and utilization of workforce up to 40% - 50% as compared to the conventional method. The construction time using IHBS can be reduced up to 48% as compared to the conventional construction method.

Abstract

Land subsidence is a geomorphological event that affects Earth’s structure and physiognomy. This phenomenon occurs when the groundwater volume changes and results in the movement and sinking of sediment. Several studies have been conducted to identify major causes or factors that may lead to land subsidence. It was found that land subsidence intensity is influenced by several factors, i.e. terrain slope and aspect, land use, soil moisture content, and distance to a river. Population density contributes to continuous changes in land use. Deep investigation of factors that contribute to land subsidence such as population density is important. This study investigated the relationship between land subsidence and population density contributing to continuous land-use changes. The study area was a highly populated slum area along the Musi River in Palembang, Indonesia. Factors that have high contribution to land subsidence were considered in developing a land subsidence susceptibility map. Susceptibility analysis was done using the Analytical Hierarchy Process (AHP) method. Land subsidence features were associated with slum features and the result revealed a significantly high correlation (r = 0.844) between actual land subsidence areas and the developed susceptibility map.
