Cut Slope Management System(CSMS) is a systematic maintenance and management system designed to prevent the collapse of cut slopes located along national roads and to minimize damages caused by slope collapse related accidents. In order to implement a maintenance and management system that will ensure safe road operation, the Korean government has started the inventory of cut slopes and developed a cut slope database since 2006. The study on the application of cut slope database is on-going and part of this study is the development of cut slope database management system (Slope-navi) using GIS technology and navigation system for the effective and efficient cut slope management using Information Technology. Using the Navigation Cut Slope Data Management System the previously developed database was checked and verified. The converted cut slope inventory data and field investigation reports of about 20,000 cut slopes were loaded in the navigation map. Through the development of the navigation's cut slope data search system, a systematic and efficient cut slope database management and operation in the prevention of slope collapse and remedial measure selection was established.

About 93$\%$ of domestic teal estate construction firms registered as the end of 2001 recorded net profits of only less than 500 million won(including firms in the red) for the term. As a result of having analyzed the ratios of sales costs and the structural ratios of sales costs for the past 10 years, it was found that there have been great changes in structural ratios of sales costs. Material costs and labor costs have gradually decreased, but outsourcing costs of processing have greatly increased. In order to find activity points which are fundamental to cost control, the methods of new activity based cost management have been pursued. The characteristics of real estate construction industry lie in the fact that contract prices (sales in) are fixed and amounts of profits differ depending on the use of costs. In order to create maximum profits from fixed contract prices, the new activity based cost management has been proposed. The control of operation budgets and management costs is designed to control their schedules and expenses in different respects. Operation budgets ate executed with specific activities and management costs are controlled as a form of material costs, labor costs, out sourcing costs and expenses which are details of expenditure. In order to execute them by using the methods of new activity based cost management, first of all, we have to analyze what activity drivers ale and how much added values such activities can create. It is considered as a method of cost management which is necessary far the survival management of real estate construction industry.

The construction industry in recent years, due to the multi-species engineering specialty, interest and importance of human resource management is growing. But, not many studies on the operation ratio are being proceeded due to the difficulty of casting people on site and actual survey. Thus, this study proposes the work type-specific quantitative operation ratio through work type-specific operation ratio analysis of reinforced concrete construction which takes up an important part of construction work.

Construction management services have been adopted for more than a decade and are continuously growing; however, the advantages of utilizing a construction management service are still not quite clear, regardless of many arguments can be made in their favor. The construction manager, as a coordinator, is supposed to smoothly facilitate the project teamwork in order to deliver a profitable and satisfactory project, not only for the owner's interests but also for the success of all project participants. This study has focused on the teamwork supports a construction manager can provide during project operations. This study developed a benchmarking tool to assess the construction manager's role in terms of its project teamwork supports, by utilizing the evaluation model and several case studies. In addition, this study also attempted to set the industry average and higher performance so that both the owner and the construction manager can self-assess, and more importantly, can improve project operation. The actual implementation of the benchmarking tool into on-going projects can allow the construction manager to understand the current operation and to make a better project process through teamwork.

This paper presents a system architecture and database of construction quality management system which encourages real time information tracking and monitoring. It improves the real time quality record tracking by using QR code technology in the project delivery. The advantages and issues relative to QR code and the database structures of the tracking system are presented. Conventional project scheduling system, operation modeling and analysis system, and quality management system are hybridized using QR code technology. The system improves project quality management by tracking the atomic tasks which consists of a construction process at the lowest level of construction hierarchy. It analyzes the quality records to determine the causes of abnormality and/or nonconformity. Using QR code technology, the construction quality management system may be more effective than the conventional one. It was confirmed that the quality management processes in construction project delivery can be more visible and controllable by integrating QR code technology, project scheduling system, and quality management system.

Currently, the quality management, safety management and environment management of domestic construction work does not form a infrastructure for integrated control which have been developed according to the unique characteristics based on respective the law. In other words, the quality manager and safety manager of human resources is set to a legal arrangement personnel, but environment manager of human resources is not. In addition, quality management standard is to perform the work to PDCA(Plan-Do-Check-Action) system which is reflected in all of the requirements of KS A ISO 9001 standard, but safety management plan and hazard harmfulness prevention plan are not properly reflected P(Plan), C(Check) and A(Action) system and focusing on only 4 section Do(D) in KOSHA 18001 standard requirement. Moreover environmental management plan is not even established requirement. Through examining the operation practices of an advanced nation prior to building the integrated control standard for construction work qualify safety.environment, the possibility of applying domestic is reviewed, and then this study is going to research the operation practices of Singapore.

Construction processes are highly repetitive. A resource entity continuously cycles through work tasks that processes or uses resources. Web-CYCLONE (Halpin 1992) has been accepted as a useful tool for modeling and analyzing a specific operation. However the system has a lack of practicality as follows: (1) it does not efficiently record and keep track of operation models in a database; (2) it does not provide the functions which facilitate to retrieve corresponding model and to update local variables of the model using observed data; (3) it does not automate the complex process that executes simulation experiment, analyzes simulation outputs and generates a report on behalf of the practitioners. Therefore, practitioners have a difficulty in reusing, modifying and analyzing the existing operation models. This study introduces a Client/Server based CYCLONE that improves above-mentioned limitations in the existing Web-CYCLONE. The system was illustrated by revising CSPU in practice.

As there are more accidents which are more serious in construction site than other industries, it needs the safety management system to be SLIM on the same time, There are still lots of difficulties to prevent those accidents exactly, so it also needs a safety supervision team to prevent the accident, unsafe operation and condition before happening, which is also called as a Man-to-Man safety management method. The range of the job site in one personnel's management is very big and large, so it needs the personnel to keep watch the safety operation and prevent any unsafe/fire accidents. Also the personnel also should find out the unsafe points in the job site, and carefully supervise the dead angle site, then support the totally safety management POINT and realize the ZERO accident.

Construction Technology Service is currently hardly managed due to failure to offer standard management system of service performance, company performance, and business evaluation in every Ordering Agencies. After Construction Technology Promotion Act is enforced in May 2014, Ordering Agency obligates them to report to Minister of Land and Transportation within 10 days upon contract/ amendment/ completion. In 2013, in advance to enforcement of this law, performance management system for construction technology service was developed for a test run. However this system only applies to main contractors while management and operation of subcontractors are unavailable that causes problems on connection and integration with Experience Management Trustee. Therefore, this research will establish systematic foundation that enables real-time information of service performance and evaluation of subcontractors to result standardization of performance and evaluation for public ordered services.
