Developing Integrated Building Indicator System (IBIS) (A Method of Formulating the Building Condition Rating)

Abstract

Integrated Building Indicator System (IBIS) is build to measure the existing building condition before repairing, upgrading and applying Total Facilities Management to a building. The building condition will become the main criteria to achieve a better built environment. The era and types of buildings become the main factor before the adaptation of facilities is planned for these buildings. The main objective of the research is to demonstrate the formula of building condition rating. The aim of this method is to create building condition rating and scale. The methodology of this study is initially to create a formula of a model based on era of the building. Factors that should be considered to carry out building condition ranking are types of building, year of built, the function of building, building condition survey and cost of remedial. As a result, there are five building condition rating based on different scale (price) from 1-5 (rating 5 is the lowest cost of each defect and rating 1 is the highest cost of each defect). The highest rating consists of minor defects of the building. Rating 1 will bring serious defects with higher cost of remedial work. The relevance of rating the building condition should be identified before adapting Total Facilities Management in a building.
