OPTIMIZATION OF TIME AND COST OF BUILDING COMPONENT MAINTENANCE: A CASE-STUDY IN A FIVE STAR HOTEL

Abstract

Building component maintenance management is one of the most important issues in management of building lifecycle costs. Key to successful maintenance management is the ability to survey present condition and predict the future condition for each component and facilities present in a building. The paper presents a process to optimize maintenance cost and time of caste iron pipe component in wastewater plumbing system of hotel building in Iran as a case study using the condition index (CI) method. The research uses a systematic assessment field as followed by the USACERL condition index method. To achieve this objective, cast iron pipe within wastewater plumbing system is surveyed using the economical tools for implementation of optimal maintenance time and cost based on highest saving to investment ratio. The research presents a financial analysis using the existing data. The data was collected through financial and technical sheet. Data is analyzed using the economical tools and financial analysis is simulated with simulation software. The purpose of this paper is to develop a financial analysis simulation for component maintenance assessment during its service life based on highest interest rate. The analysis results in to identify optimum maintenance time basing on the limited cost. This method helps to facilities managers and engineers to make better decisions for reducing maintenance costs and increasing the component’s service life.
