Building remodeling concept includes maintenance & repair and renovation. We have long-term repair plan and special repair fund system for the apartment maintenance & repair, but they do not operate well. And laws and ordinances are being revised in relation with renovation. However, more policy improvement and assistance are needed in order to activate the apartment remodeling project. Especially preferential loan and tax reduction policy and deregulation of building provisions are the main tasks for the apartment remodeling.

Knowledge acquisition, maintenance of knowledge base, and validation and verification of knowledge are the addressed bottlenecks of building successful knowledge based systems. Along with the increment of interesting in the knowledge based systems, the organization needs to develop a new one although it has a similar one. This causes several serious problems including knowledge redundancy and maintenance of knowledge base. This paper present three models of the reusable knowledge base which might be the solution to the above problem. Three models are : 1) multiple knowledge bases for a single AI application, 2) multiple knowledge bases for multiple AI applications, 3) a single knowledge base for multiple AI applications. A new approach to build such a reusable knowledge base in a homogeneous environment is presented. Our model combines the essential object-oriented techniques with rules in a consistent manner. Important aspects of applying object-oriented techniques to AI are discussed (inheritance, encapsulation, message passing), and some potential problems in building an AI application (decomposition technique of knowledge, search time, and heterogeneous environment) are pointed out. The models of a reusable knowledge base provide several amenities : 1) reduce the knowledge redundancy, 2) reduce the effort of maintenance of the knowledge base, 3) reuse the resource of the multiple domain knowledge bases, 4) reduce the development time.

This study as a demand of reconstruction allows the longevity of the multi complex, analyze the problems and solutions for a long term maintenance planning scheme, and how to save contingency fund to utilize. The major role of the multi complex housing market reflects Positively on our valuable society, provides a better life of environment on top of longevity and for the superior living duality. For a achievement and improvement existing long term maintenance Plan and contingency fund system should be considered as follows. First, shall be expanded more units of house as smaller group. Second, advice from expert shall be reconsidered, eliminated, and protected reorganizing an informal reconstruction planning comparatively legal procedure must be renegotiated and pursued. Third, the fund which saved for the contingency has to clarified as tax free item by government. It's not only mistreated as a limitation of personal asset but also treated as national source Despite of rather compulsive and constructive method must be noticed by whoever owns for, more positive follows, promotion and directing must be able to guide its understanding and adherence of importance and inevitability.

Integrated construction site management using RFID(Radio Frequency Identification) and facility maintenance introducing USN (Ubiquitous Sensor Network) have been widely used in the mega construction project sites. But, the validation on performance of RFID systems after introducing those has not been carried out. Given that the use of RFID systems have been increased, the construction industry as well as other industries needs the evaluation of the RFID system. By regarding the necessities for evaluation, a research to the satisfaction and importance evaluation of RFID system from the end-users' view point for site management was conducted. Satisfaction-importance matrix of satisfaction standards and importance standards was created (organised) according to the analysis result of a survey, proposed improvement methods and analysis about the items presented by each region like areas of sustainable maintenance, maintenance, progressive improvement and priority improvement. The result would contribute to enhance the utilization of system and its performance.

The purpose of this study was to find out the most reasonable design in the superstructure of an underground parking lot which needs to be considered with the economic efficiency being influenced on the subdivision price, construction duration, workability and the maintenance of crack and leakage status of apartment house. In this research, we've evaluated the fitness for the superstructure of an underground parking lot by examination of construction constraint, which was based on the calculated data of structural design and quantity survey. The results of this study are summarized as follows. 1. The system of the absent structure of beam is proper structure for economic efficiency, construction duration and workability, but it is disadvantageous at the side of maintenance efficiency because of the many part of large slab. In the opposite direction, the establishing structure of beam has the advantages of structural stability except economic efficiency, construction duration and workability 2. It's required a proper selection for the views being contrary to each other which the owners considers good quality, on the other hand, the contractors consider construction duration and workability. 3. In making a selection for the superstructure of an underground parking lot, we have concluded that it is the most important to choose the proper structure for the demanded performance by contrasting with two system.

General criteria for the quality of porous concrete have not been established yet in Korea. And yet, pavement and construction have been performed. In this paper, guidelines on the construction site quality control of porous concrete were developed in order to establish criteria for resolving the issues and problems of porous concrete, to establish methods for improving poor performance, and to manage porous concrete more systematically. In addition, a guide for the construction site quality control of porous concrete, which was appropriate for reality, was developed by researching several quality control guides and maintenance at construction sites. The guide consists of a total of nine chapters such as Application Range, Overview, the Structure of Porous Concrete, the Design of Package Thickness, Package Materials for Porous Concrete, Construction Methods, Quality Assurance and Inspections, Construction Site Quality Control, and Maintenance. It describes quality control guidelines in all steps such as methods for transporting porous concrete from the factory to the construction site, cautions for construction work at construction sites, maintenance, and management. The Guide for the Construction Site Quality Control of Porous Concrete is expected to ensure the quality of porous concrete, to reduce national costs for quality assurance, and to help ensure the health and safety of Korean people.

This study aimed to address the issue that about 92% of domestic BIM orders only focus on the design/drafting stage and the absence of government BIM implementation guidelines for maintainers. Despite the ability of BIM to reduce maintenance LCC by around 20%, such guidelines remain insufficient. In this study, we examined the COBie requirements by comparing 45 maintenance information and Autodesk Revit (2022) inputs with COBie data. As a consequence, the necessary elements correlated with 54 pieces of data across eight spreadsheets (Contact, Space, Type, Component, System, Spare, Job, Document) and there were 13 gaps in information between the construction and maintenance. These were subsequently integrated into the ontology and their associations were evaluated with the Reasoner tool. From the results inferred, it is apparent that the COBie requirements have a correlation with one another. It is essential to carry out a survey among practitioners and a pilot operation to assess performance in the future. This research is anticipated to furnish pivotal data for the implementation of an effective property upkeep system.

As buildings become larger and more complicated, construction costs have increased with a considerable effect on buildings' Life Cycle Cost (LCC). However, there has been little consideration on economic aspects in the selection of construction materials due to limited information on the materials and dependency in architects' experience and inefficiency in cost estimation, causing design changes, increase in maintenance cost, difficulty in budgeting, and decrease in building performance. To solve these problems, this study proposed a BIM-based material selection model which reflects the comprehensive economic efficiency of building materials. Our cost prediction model can estimates the material-related cost during the entire building life cycle. Furthermore, we implemented the proposed model in connection with BIM, which can analyze and compare LCC by material. Through the validation of the model, we could confirm the necessity of LCC-based material selection in comparison with the conventional cost-centered material selection.
