Safety inspection activities of the facilities including the electricity, gas, building, and firefighting, etc. are individual checks by the separate law of each government department, comprehensive inspections for the specific managed facilities or during a weak season, and national safety overall diagnostics for the disaster prevention. Thus, types of the inspections are various and they have been carried out repeatedly as well as duplicately. That can make the people or institutes to take such inspections feel great burdens. Therefore, the investigation on the current situation of the individual inspection by the separate law for the electricity, gas, building, and firefighting, etc. as well as of various others by the government needs to be carried out and according to the results the repetitive and duplicated inspections should be reduced and converged to one comprehensive one. In this regard, we proposed solutions to improve the government safety inspection system, function, and role.

This study was conducted a survey for suggesting direction of improvement of on­site inspections in Korean construction industry. The survey is limited perspective of owners, contractors and construction managers (including supervisors) about existing 'construction field inspection manual' with field inspections (eg. central inspection, central quality safety unit inspection etc.): focusing on stakeholder's perception and actual state of inspections.

Even though continuous management and supervision of reinforcement of policies to safeguard accidents at workplace and work sites were implemented. Accident prevention activities such as inspection and diagnosis are urgently required to induce a preliminary investigation to identify the risk factors for each type of work, before the work task to eliminate risks at the worksites. Since safety inspections at work sites were generally conducted through visual inspections, the results of safety inspections may vary depending on the findings and proficiency of the safety officers. The results of those inspections may have loopholes to prevent potential accidents at work. Therefore, the purpose of this study was to develop a risk identification checklist that can effectively perform safety inspections to prevent accidents at work sites. This study initially analyzed the previously developed accident checklist to identify current complications and issues in safety checklists. Based on the findings of major industrial accidents over the past three years, the relationship between accident, workplace, and work type were analyzed refereeing the safety inspection standards. A risk recognition-checklist was developed to provide basic data on identifying risk factors, and inspection guidance at work sites. To prepare for potential accidents by identifying and taking countermeasures to mitigate the high risk and serious accidents at sites by the guidelines of the checklist. The developed inspection checklist has been practically used by experts at work sites to perform safety inspections, and it has been verified its suitability, and feasibility, to prevent or mitigate workplace accidents, including securing the safety and health of field workers. The role of the developed safety checklist has been considered effective at worksites.

The Korean government had enacted 'Special Regulation on the Safe Maintenance of Facilities' and carried out regular safety inspections since the mid-1990s, consequently establishing and enforcing an effective maintenance and management system. And throughout this entire process, the government searched for new methods to increase the overall effectiveness of the system. Nevertheless, the reality is that our society remains structurally unprepared to implement a commercial mindset that views the concept of "safety" as a product that can be traded in the open market based on supply and demand. Therefore, the government should establish mid to long-term plans to implement such a system in successive stages.

The purpose of this paper is to understand the key factors for efficient maintenance of rapidly aging facilities. Therefore, the safety inspection/diagnosis reports accumulated in the unstructured data were collected and preprocessed. Then, the analysis was performed using a text mining analysis method. The derived vulnerabilities of tunnel facilities can be used as elements of inspections that take into account the characteristics of individual facilities during regular inspections and daily inspections in the short term. In addition, if detailed specification information and other inspection results(safety, durability, and ease of use) are used for analysis, it provides a stepping stone for supporting preemptive maintenance decision-making in the long term.

In Current artificial structures, we must periodically make their safety inspections. In this process, we should consider the safety of workers and the accuracy of safety checks and also consider time and cost savings for safety inspections. Additionally, in the fields of architecture and civil engineering, we are unavoidable the use of foreign commercialized BIM model tools. To address these challenges, we propose mapping crack areas and BIM 3D design drawings based on augmented reality (AR) for the safety inspection of Huge Bridges. For this purpose, we define indexing of 2D/3D drawing models, create the tabulation of all 2D/3D drawings into a database, analyze QR codes, and finally integrate with augmented reality devices. we may expect our method to improve the efficiency of safety inspections on bridge sites. Moreover, we will enable the domestics of our pure technology.

우리나라는 안전점검을 의무적으로 시행하여야 하는 국가시설물이 증가하고 있으며, 또한 보다 안전한 안전점검 방법이 필요한 시점이다. 본 연구는 주로 육안조사에 의존하던 교량의 안전점검을 드론을 활용하여 수행함으로써 점검자의 안전을 확보하고 신속한 외관조사가 가능하게 함으로써 교량 안전점검 외관조사의 효율성을 높이고자 하였다. 연구를 위하여 인천의 영종대교를 테스트베드로 선정하고 와렌 트러스 부분, 현수교 메인 케이블, 주탑, 교각의 네 부분으로 나누어 드론 촬영을 실시하고 성과물을 제작하였으며 그 과정에서의 작업 내용들을 정리하고 분석하여 교량시설물에 대한 드론 안전점검시 다섯 단계의 표준절차를 정립할 수 있었다. 연구결과로 얻어진 표준절차의 단계별 내용은 1단계, 시설물 정보수집 및 분석, 2단계, 취약부 분석 및 비행계획, 3단계, 드론 촬영 및 데이터 처리, 4단계, 외관조사 상태평가, 5단계, 외관조사망도 및 DB 구축이다. 따라서 이 표준절차에 따라 교량을 포함한 토목시설물의 안전점검이 수행된다면 보다 체계적이고 효율적으로 안전점검을 수행해 나갈 수 있을 것으로 기대된다.

P-PIE is a program developed to estimate failure probability of pipes and pressure vessels considering fatigue and stress corrosion crack growth. Using the program, crack growth simulation was performed with an initially existing crack in order to examine the effects of initial crack depth distribution on the leak probability of pipes. In the simulation stress corrosion crack growth was considered and several crack depth distribution models were used. From the results it was found that the initial crack depth distribution gives great effect on the leak probability of pipes. The log-normal distribution proposed by Khaleel and Simonen gives lower leak probability compared other exponential distribution models. The effects of the number and the quality of pre-service and in-service inspections on the leak probability were also examined and it was recognized that the number and the quality of pre-service and in-service inspections are also give great effect on the leak probability. In order to reduce the leak probability of pipes in plants it is very important to improve the quality of inspections. When in-service inspection is performed every 10 years and the quality of inspection is above the very good level, the leak probability shows nearly constant value after the first inspection for an initially existing crack.

최근 국내 주요 SOC 시설물의 사용 연수가 30년 이상을 넘어가고 있어, 10년 내 노후화가 급속도로 진행될 것으로 예상되면서 시설물의 선제적 유지관리에 대한 필요성이 대두되고 있다. 이에 따라 유지관리 분야에도 스마트 점검 기술을 도입하기 위한 연구가 다수 수행되고 있다. 하지만 현재 시설물 유지관리는 인력위주의 안전점검 및 진단에 맞춰 제도가 마련되어 있어, 실제 현장에서 육안조사에 의존하여 조사가 이뤄지고 있는 실정이다. 인력점검의 경우 점검시간이 과다 소요되고 결과 분석 시에 주관적인 오류 등이 발생할 수 있으며, 터널의 경우 일부 구간 차단으로 사회간접비용 손실 등이 발생한다는 단점이 있다. 따라서 스마트 안전점검을 제도적으로 도입하기 위해서는 첨단 장비 사용, 전문가 자격 변경 등 구체적인 방안 마련을 위한 검토가 필요하다. 또한 제도적 변경에 앞서 첨단 장비를 통한 안전점검 결과에 대한 확인 및 검증이 필요하므로, 국가차원의 공식적인 연구나 검증 기관 운영 등이 필요하다. 이를 통해 유지관리 분야에 스마트 점검 기술이 도입되면, 터널 등 SOC 시설물의 일상적인 점검이 가능해질 것으로 예상된다. 결과적으로 시설물 상태변화에 의한 안전사고를 미리 인지하고 선제적으로 대응할 수 있는 유지관리 기술이 정착될 수 있을 것으로 기대된다.
