Development of life-cycle analysis based new bridge management system in Korea

To meet the requirements of 21st century, Kuwait ministry of public works have realized that they should use modern technologies and management system to face challenges of modern world. So, they maintenance Administration has launched a massive program which helps to meet development needs and helps to maintain the infrastructure’s sustainable growth. Thus, it is very necessary to develop appropriate bridge maintenance strategies to meet serviceability criteria and life cycle cost optimization of new bridges. And main purpose was to meet the requirements of development needs. Bridge management system (BMS) is a software or we can say a management tool which helps us to maintain or manage the bridges. These are the following main points which helps decision makers to make a best decision. Defines bridge condition, identifies bridge needs for like if we need replacement of any material or renovation can be identified by BMS, cost of bridge during maintenance and management of the bridge, identifies bridges for Replacement and rehabilitation programs (MR & R) and also identifies for the assessment of bridges. According to replacement and rehabilitation programs minor changes or maintenance of the bridges is done by Work management system (WBS). This paper proposes a framework that can enhance the effectiveness of Kuwait’s Integrated Maintenance Management System (KIMMS). A survey for bridge contractors around the world was used as the research method for this study. This contains questions regarding their current bridge management system (BMS) and what are the input and output parameters it considers in the process. BIM (Bridge information modeling) technology is used to reduce the errors in designing and construction of the bridges by using BMS, BRIDGE OWNER may have a sustainability in the maintenance and enhancement of its bridge. We can determine the cash flow to be used in future for the replacement and repairment of bridge. It helps to adopt maintenance program to maintain life-cycle costs for the community. Helps to review the replacement and rehabilitation strategies. Helps to improve the economic life of infrastructure assets. After evaluating the BMSs used by the respondents, it turned out that the most effective procedure should have three main processes to be followed; maintenance planning, maintenance optimization, and maintenance decision support. Overall, the conceptualized framework considers an optimized procedure for maintenance management considering the balance in cost and quality of the process.

The Status

A significant part of Ukrainian bridges on public roads is operated for more than 30 years (94 %). At the same time, the traffic volume and the weight of vehicles has increased significantly. Insufficient level of bridges maintenance funding leads to the deterioration of their technical state. The ways to ensure reliable and safe operation of bridges are considered. The procedure for determining the predicted operational status of the elements and the bridge in general, which has a scientific novelty, is proposed. In the software complex, Analytical Expert Bridges Management System (AESUM), is a function that allows tracking the changes in the operational status of bridges both in Ukraine and in each region separately. The given algorithm of the procedure for determining the predicted state of the bridge using a degradation model is described using the Nassie-Schneidermann diagram. The model of the degradation of the bridge performance which is adopted in Ukraine as a normative one, and the algorithm for its adaptation to the AESUM program complex with the function to ensure the probabilistic predicted operating condition of the bridges in the automatic mode is presented. This makes it possible, even in case of unsatisfactory performance of surveys, to have the predicted lifetime of bridges at the required time. For each bridge element it is possible to determine the residual time of operation that will allow predict the state of the elements of the structure for a certain period of time in the future. Significant interest for specialists calls for the approaches to the development of orientated perspective plans for bridge inspection and monitoring of changes in the operational status of bridges for 2009-2018 in Ukraine. For the analysis of the state of the bridge economy, the information is available on the distribution of bridges by operating state related to the administrative significance of roads, by road categories and by materials of the structures. Determining the operating state of the bridge is an important condition for making the qualified decisions as regards its maintenance. The Analytical Expert Bridges Management System (AESUM) which is implemented in Ukraine, stores the data on the monitoring the status of bridges and performs the necessary procedures to maintain them in a reliable and safe operating condition. An important result of the work is the ability to determine the distribution of bridges on the public roads of Ukraine, according to operating conditions established in the program complex of AESUM, which is presented in accordance with the data of the current year. In conditions of limited funding and in case of unsatisfactory performance of surveys, it is possible to make the reasonable management decisions regarding the repair and the reconstruction of bridges.
