The key role in safety management is to identify any possible hazard before it occurs by identifying any possible risk factors which are critical to risk assessment. This planning/assessment process is considered to be tedious and requires a lot of attention due to the following reasons: firstly, falsework (temporary structures) in construction projects is fundamentally important. However, the installation and dismantling of those facilities are one of the high risk activities in the job sites. Secondly, temporary facilities are generally not clearly delineated on the building drawings. It is our strong belief that safety tools have to be simple and convenient enough for the jobsite people to manage them easily and be flexible for any occasions to be occurred at various degrees. In order to develop the safety assessment system, this research utilizes the BIM technology and collects important information by importing data from BIM models and use it in the planning stage.

Almost accidents in construction sites are occurred by unsafe work conditions and failure making safe environment. As recent construction projects become more complex, various and diversified, So the potential of construction-related accidents is increased as well. Comparing the frequency of construction-related accidents in large-sized construction sites, small-sized construction sites are more vulnerable because of lack of workforce and less effective technology system. Furthermore, the absence of safety committee, poor financial condition leads to lack of safety education, installation of safety facilities, and provision of individual protective equipment, which indicates difficulties handling even basic safety management. Therefore, in order to lower the hazard rate at small-Sized construction sites, it is necessary to proceed with more structural and thorough actions for preventing accidents. In other words, it is necessary to analyze the causes of the accidents at small-sized construction sites, set criteria for safety management, and suggest safety management items according to work classification by evaluating the relative importance of the items.

Recently, many business and government organizations have benefitted by executing projects using TOC-CCPM(Theory of Constraints-Critical Chain Project Management). In parallel, Earned Value Management(EVM) metrics have also become popular. Many organizations like US government requires that all large projects measure and report project progress status using EVM. Thus, project management in business fields such as plant construction, IT development, ship building need to integrate TOC-CCPM and EVM in oder to keep and reduce the delivery date of projects for improvement of customer satisfaction and enlargement of business opportunity. This paper proposes the scheme and case of developing the Synchro-EVM system which TOC-CCPM and EVM are connected.

국내 건설재해율은 1992년 도입된 이후 현재까지 PQ에 '환산재해율' 반영 등을 통하여 건설재해 감소 및 건설업 안전관리 체제 구축에 기여하고 있다. 또한, 최근 정부가 도입 추진 중인 종합심사낙찰제에도 '재해율' 및 '사망만인율'이 평가항목으로 구성되어 입 낙찰제도의 그 영향력이 확대되고 있다. 그러나 현행 건설재해율은 입 낙찰제도에 따라 이원화된 기준으로 산정 및 운영되고 있는 실정이므로 현 시점에서 건설재해율 평가지표에 대한 현황 검토와 효율적 운영을 위한 방안이 모색될 필요성이 대두되고 있다. 이에 본 연구에서는 건설업체의 재해관리 실무자를 대상으로 설문조사를 실시하여, 현행 건설재해율의 평가 운영에 대한 현황 검토를 통하여 문제점을 분석하고 그에 따른 개선방안을 제시하였다. 연구 결과, 건설재해율 평가지표의 일원화를 위한 산정기준, 평가대상업체 범위 설정, 건설업 공상처리 개선 측면에서의 개선방안을 제시하였다. 제시된 개선방안을 통해서 보다 효율적이고 합리적인 건설재해율 평가지표의 산정 및 운영이 가능할 것이며, 나아가 건설업체의 자율적인 안전보건 활성화 등을 통한 건설 재해 감소 효과를 기대할 수 있을 것이다.

Despite the government 's efforts to reduce constructional disasters, it has been pointed out that the safety management cost of the Construction Technology Promotion Act does not reflect the actual site. Therefore, it is necessary to study the proper guideline of the safety management cost which can be used as the most fundamental measure to prevent construction accidents. Moreover for the securement of the reasonable safety management costs, it is important to calculate its appropriate rate. Thus, in this study, the appropriate rate of safety management cost was proposed by the construction cost & type based on the 111 execution plans of safety management cost, and the rate is analyzed to be 1/10 of the occupational safety and health management cost. The results of this study will be a guideline in improvement to the proper schedule rating system improvement and in implement of pilot projects.

For construction projects it is imperative that site management gives the highest priority to planning safe site evacuation for all foreseeable emergencies, including earthquakes and typhoons which are often experienced in Japan. This is especially important and even more critical for high risk projects involving underground works, such as Tunneling & Pneumatic Caissons. Based on the safety regulation of underground works, a back-up power supply system must be provided during the construction period at all times. Often, fluorescent lamps with re-chargeable batteries are provided for infrequent emergency cases, however these have a questionable useable life span and thus need careful maintenance and periodical replacement. In this paper we focused on using the phosphorescence materials to indicate the evacuation direction. As a result, it was confirmed that the phosphorescence materials were considered useful in reducing panic and facilitating a controlled evacuation in the event of a total black-out due to power failure.

Objectives: This paper presents the framework and protocol design for a construction industry risk management toolbox. The construction industry needs a comprehensive, systematic approach to assess and control occupational risks. These risks span several professional health and safety disciplines, emphasized by multiple international occupational research agenda projects including: falls, electrocution, noise, silica, welding fumes, and musculoskeletal disorders. Yet, the International Social Security Association says, "whereas progress has been made in safety and health, the construction industry is still a high risk sector." Methods: Small- and medium-sized enterprises (SMEs) employ about 80% of the world's construction workers. In recent years a strategy for qualitative occupational risk management, known as Control Banding (CB) has gained international attention as a simplified approach for reducing work-related risks. CB groups hazards into stratified risk 'bands', identifying commensurate controls to reduce the level of risk and promote worker health and safety. We review these qualitative solutions-based approaches and identify strengths and weaknesses toward designing a simplified CB 'toolbox' approach for use by SMEs in construction trades. Results: This toolbox design proposal includes international input on multidisciplinary approaches for performing a qualitative risk assessment determining a risk 'band' for a given project. Risk bands are used to identify the appropriate level of training to oversee construction work, leading to commensurate and appropriate control methods to perform the work safely. Conclusion: The Construction Toolbox presents a review-generated format to harness multiple solutions-based national programs and publications for controlling construction-related risks with simplified approaches across the occupational safety, health and hygiene professions.

"Act on Facilitation of Purchase of Small and Medium Enterprise - Manufactured Products and Support for Development of Their Markets" was created and implemented. The act states that the materials designated by the Small and Medium Business Administration are directly purchased from the small and medium enterprises and provided to the construction companies so that the materials can be provided as GFGI (Government Furnished and Government Installed) in the case of a public construction project. This thesis is aimed to analyze the current status on the problems of each project party and understand their improvement requests so that mutually beneficial plans can be sought and improved process is presented for the continuous development of the direct construction material purchase system as well as successful construction projects. And This thesis summarized the purpose of the institutions and their change histories, and related law as well as codes for the better understanding of administrative procedures for the purchase system and the analyses as well as the improved process on the difficulties in complying with the current institutions.
