Abstract

A safe and comfortable study environment enhances educational performance. Thus, effective and efficient school facility management is very important. However, present school management systems are unreasonable because they depend mostly on the decision of the school principal or of non-expert administrators of educational facilities, instead of being based on the reliable Life Cycle Cost (LCC) data or information. The experts are often surprised to see a marked difference between their projected educational facility maintenance cost and the actual cost. The LCC of educational facilities produces a voluminous amount of quantitative data. Much of these data is created during the construction and maintenance phase of an educational facility and is related to cost, time, safety, quality, and administrative information. Recent storage and processing advances in computers increase the opportunity to monitor educational facilities in ways fundamentally different from those of the existing systems. However, the lack of a fundamental model of multidimensional data representation contributes to the inadequate application and implementation of the historical data in educational facility management. Therefore, this research presents a basic method of using data warehousing that will supply objective and reasonable LCC data or information for effective educational facility management.

Abstract

The Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is of utmost importance1. Despite the intense flow of information between design and LCC (Life Cycle Cost) professionals, there is a lack of research to better understand and manipulate these processes. Architecture design and LCC management is a process of planning a tangible building and cost on a tangible land through intangible work. Due to this characteristic of design work, conventional design management was conducted around the drawings as the final outcome, but actual individual processes of design and LCC (Life Cycle Cost) planning for facility were excluded. As a result, design work and LCC planning completely depended on the individual abilities and experiences of each architect and LCC planner. Even organization of information required for design and LCC process are considered to belong to the domain of individual ability. Therefore, this study proposes an integrated system development methodology of design and LCC process for an information oriented design and LCC management system, which allows architects and LCC planners to easily access information to be provided in each design stage and its relevant LCC planning process, and for design and cost management companies to improve the performance through the systematic storage and usage of data after the completion of an educational project. This research analyzes actual design and LCC processes in currently active companies and proposes a standard design and LCC process, and then examines input and output information for each task in the process in order to propose an information oriented standard design and LCC process. Based on this, Data Flow Diagram (DFD) and Entity Relationship Diagram (ERD) is designed for an information oriented design and LCC management system.
