건설업은 국내 산업 중 안전사고가 가장 많이 발생한다. 건설업의 재해는 막대한 재산손실과 인명피해로 인한 사회적 문제로 이어지기 때문에 더 각별한 주의를 기울여야 한다. 최근 이로 인해 건설업에서 발생하는 재해에 대한 경각심이 높아지고 있으며 정부 각 부처에서는 안전관리에 관한 규정을 강화하고 있다. 특히 산업안전보건공단에서는 이번 산업안전보건법 전부개정안에서 보호대상의 확대와 책임소재의 명확화에 중점을 두고 있다. 이에 따라 발주자 책임에 의한 안전관리를 중심으로 분석한 연구가 필요한 실정이다. 따라서 본 연구에서는 건설사업관리자의 사업수행능력평가를 산업안전보건법의 전부개정안을 고려하여 안전항목을 고려하여 건설사업관리자를 선정하는 방안을 제시하고자 한다.

This paper presents a tool called Quality-Cost optimization system (QCOS), which integrates Multi-Objective Genetic Algorithm (MOGA) and Quality Function Deployment (QFD), for tradeoff between quality and cost of the unitized metal curtain-wall unit. A construction owner as the external customer pursues to maximize the quality of the curtain-wall unit. However, the contractor as the internal customer pursues to minimize the cost involved in designing, manufacturing and installing the curtain-wall unit. It is crucial for project manager to find the tradeoff point which satisfies the conflicting interests pursued by the both parties. The system would be beneficial to establish a quality plan satisfying the both parties. Survey questionnaires were administered to the construction owner who has an experience of curtain-wall project, the architects who are the independent assessor, and the contractors who were involved in curtain-wall design and installation. The Customer Requirements (CRs) and their importance weights, the relationship between CRs and Technical Attributes (TAs) consisting of a curtain-wall unit, and the cost ratios of each components consisting curtain-wall unit are obtained from the three groups mentioned previously. The data obtained from the surveys were used as the QFD input to compute the Owner Satisfaction (OS) and Contractor Satisfaction (CS). MOGA is applied to optimize resource allocation under limited budget when multi-objectives, OS and CS, are pursued at the same time. The deterministic multi-objective optimization method using MOGA and QFD is extended to stochastic model to better deal with the uncertainties of QFD input and the variability of QFD output. A case study demonstrates the system and verifies the system conformance.

공사관리자는 가용자원을 최대한 합리적으로 사용하고 주어진 공사기간과 예산 범위 내에서 건설 프로젝트를 완료하기 위해 노력하며, 공사기간 내에 프로젝트를 끝내기 위해 바차트나 CPM과 같은 공정표를 활용한다. 제주지역의 소규모 건설회사나 현장에서는 건설공사를 수행하기 위한 도구로 공정관리 전문 소프트웨어보다는 엑셀을 많이 사용하는 것으로 조사되었다. 이는 엑셀이 원가와 연계하여 사용하기 편리하고 공정관리 소프트웨어를 활용할 전문가도 부족하기 때문이다. 대학은 지역의 중소규모 건설회사가 요구하는 공정관리 능력을 가진 인재를 배출하고 있지만 교육의 질적 및 양적 측면에서 다소 부족하다. 지방 국립대 건축공학의 교육과정 조사에 의하면 대부분의 학과는 공정관리과목이나 유사한 과목을 편성하고 있다. 주요 교육내용은 네트웍 공정관리기법에 대한 이해와 공정표 작성으로 이루어져 있다. 공정관리 소프트웨어에 대한 교육과 실습은 일부 대학에서만 이루어지고 있으므로 중소규모 건설현장의 공정관리 전문가를 양성하기 위해서는 바차트 활용과 전문 공정관리 소프트웨어 교육도 필요하다.

The execution of a construction project involves the engagement of many participants. Generally, the Authority uses CM to certify that the Work is built according to the contract documents. The CM work scope is expressed in the Construction Technology Management Act and its Regulation. The mandated and delegated CM services are limited to the construction period. If Contractor is required to repair a construction defect, the Contractor should bear the burden of the inspection service for the defect repair, because it is associated with him. Nevertheless, CM should submit a bond to provide the inspection and supervision service for the defect repair. These may result in conflict with each liability. Therefore, CM service in the law and regulation was investigated and analyzed in this study to classify the characteristics of CM contracts, and it was suggested that the CM liability for the inspection and supervision service for the defect repair should be reconsidered.

In recent years, the number of female workers pursuing careers in the construction engineering and management field has increased, despite the fact that the job positions have been traditionally considered as retaining job functions and/or qualities that are more appropriate to male than female. This may be attributed to the fact that the positions also require delicate and/or detail-oriented job functions, which can be successfully performed by female. It is important for project participants to understand the working conditions for female field managers by analyzing their job performance. This study collects expert opinions regarding female's managerial performance on job site. Survey questionnaires were administered to two focus groups, male and female field managers who work for general contractors. This study contributes to encouraging female's social and economic involvement by investigating the challenges they face in the workplace, and provides measures to respond to such challenges.

We carry out a demonstration project to verify performance of a Home- Smart Cabinet Panel(H-SCP) at the child care facility. It is difficult to prevent an electrical disaster using a existing cabinet panel because electrical events are invisible and unforeseeable. So we construct a integrated information system with a Home-Smart Cabinet Panel(H-SCP) for management of low-voltage customers. The integrated information system with the H-SCP maintain the transmitted data from H-SCP, alert a electrical event to a administrator and show a state of customer health in real time respectively. A manager of electrical safety can prevent electrical disaster to maintain electrical facilities after analysis on the integrated information system.

SE generally defines approaching ways of conducting identification, verification and integration of an optimized product and process solution to meet customer's needs by leveraging organizational competency in engineering and management. To successfully develop a new product under mass production contract, it is important to efficiently carry out the program by ensuring that three major competencies are secured; core technology, system integration, and program management. For successful implementation of tasks in the three areas, systematic execution is called for, which requires identifying risk factors in advance. In particular, comprehensive risk management role and responsibility is required for program management. Success of a development program is determined by complex elements of human resources, organization culture, and overall competency of an organization in technology and program management, including capability of the program manager. In this paper, a risk management solution is suggested to lead a program to success with a more efficient way through actual risk management by the concept of SE around the above three areas.

In oder to predict the dispersion of a thermal discharge with strong turbulent and buoyant effects, the development of a numerical model using turbulence model and its application are significantly increased. In this study, a three-dimensional steady-state model for the surface discharge heated water into quiescent water body is developed. For the model closure of turbulent terms the four-equation turbulence model is used. For economic mumerical simulation, the elliptic governing equations are transformed to the partially parabolic equations. In general, the simulated results by the present model agree well with the experimental results by Pande and Rajratnam (1977). The model characteristics are presented in comparison with the predicted results from the two-eqauation turbulence model by McGuirk and Rodi (1979).

Low carbon construction is an important operation management goal such as cost, time, and quality in construction community. This paper introduces a system which measures the variability of carbon dioxide amounts. First, this system allows creating construction operation models of which the level of detail is breakdown into the work task level. Second, the system implements sensitivity analysis along with a ranges of resources that are allocated in an operation model. It facilitates to find the optimal resource combination using the operation performances such as the amount of emissions, operation completion time, and cost. Lastly, it identifies the best fit probability distribution functions of performance criteria given a certain resource combination. It allows project manager to query the percentages to complete the operation within a limitation specified by the system users.
