The evaluation items to assess the consumer needs are thought to be varied depending on their age, education and income. It should be noted that consumer needs are getting too diversified to notice them in time due to the rapid economic, social and cultural development. It is, therefore, considered improper to try to assess the level of consumer satisfaction and correct consumer needs by employing one evaluation method for the vastly diversified consumer types. This research is going to conduct a written questionnaire survey to the apartment dwellers in order to identify like dweller groups according to their age, income and education. Then the scope of personal characteristics of each group will be identified and the importance assessment model will be developed. Then the items on the POE will be weighted according to the assessed importance. Finally a method of developing the customer satisfaction index will be produced to quantify how much the consumers are satisfied with the project.

Steel-precast ultra-high-performance concrete (UHPC) composite beams with demountable high-strength friction-grip bolt (HSFGB) shear connectors can be used for accelerated bridge construction (ABC) and achieve excellent structural performance, which is expected to be dismantled and recycled at the end of the service life. However, no investigation focuses on the demountability and reusability of such composite beams, as well as the installation difficulties during construction. To address this issue, this study conducted twelve push-out tests to investigate the effects of assembly condition, bolt grade, bolt-hole clearance, infilling grout and pretension on the crack pattern, failure mode, load-slip/uplift relationship, and the structural performance in terms of ultimate shear strength, friction resistance, shear stiffness and slip capacity. The experimental results demonstrated that the presented composite beams exhibited favorable demountability and reusability, in which no significant reduction in strength (less than 3%) and stiffness (less than 5%), but a slight improvement in ductility was observed for the reassembled specimens. Employing oversized preformed holes could ease the fabrication and installation process, yet led to a considerable degradation in both strength and stiffness. With filling the oversized holes with grout, an effective enhancement of the strength and stiffness can be achieved, while causing a difficulty in the demounting of shear connectors. On the basis of the experimental results, more accurate formulations, which considered the effect of bolt-hole clearance, were proposed to predict the shear strength as well as the load-slip relationship of HSFGBs in steel-precast UHPC composite beams.

As the definition of the vendor-oriented implementation method, which was utilized in adopting an ERP system, has been centered around the project construction business, it was difficult for the EPR adopting organization to systematically prepare ERP projects and have enough deliberative opportunities to change-related policies. Furthermore, this method does not have a fully standardized construction process. Accordingly, by defining an organization that wants to adopt an ERP system as a customer, this paper develops the customer-based ERP construction process framework that assists both customers and developers who construct the system. For this purpose, this paper reviews the previous research and collects the construction processes of the commercial ERP SW vendor and ERP construction cases while proposing the three-layer process framework to construct ERP through the KJ method. The ERP process framework consists of 7 processes, 32 activities, 141 tasks while providing definitions for concepts of each component. Furthermore, the proposed processes and phases were set in order of the recommended execution, while the activities were suggested as an open-ended type so that the application and usability can be increased and polished by reflecting experts' opinions. The contribution of this study is to standardize the ERP project process by transforming the previous supplier-based ERP construction method into the customer-based one while providing important procedure and activity frameworks that apply to diverse ERP solutions per vendor. At the same time, this study provides an theoretical foundation to develop the construction process for the customer -based Cloud ERP. In practice, At the beginning of the ERP system construction project, it provides communication or process tailoring tools for the stakeholder.

우리나라 학교건축은 1990년 중반 이후부터 교육환경의 개선을 위한 시설확충과 노후화된 교육시설물을 유지관리 하기 위한 각종 보수공사의 비용이 증가하고 있다. 교육시설사업을 유지하는 각 주체들간 업무를 수행함에 있어 정보의 분절과 검사방법의 판단기준이 미비하여 한정된 재원의 중복투자 및 낭비를 하고 있다. 따라서 업무절차에 따른 발생정보 및 요구정보를 명확하고 일관되게 제시할 필요성이 제기된다. 학교시설물을 유지 관리 하는 단계에서 이루어지는 업무를 파악하고, 교육청에서 이루어지는 업무를 중심으로 각 기능간 문제점 및 장애요인 분석을 통해 개선프로세스 모델을 제시하고자 한다. 향후 기능간 장애요인 추출을 통한 개선프로세스 모델과 정보 모델구축이 수행되어야 한다.

Due to the effects of COVID-19 and the Fourth Industrial Revolution, construction engineering education has been required to change. As part of efforts to respond to changes, innovative teaching methods such as team-based learning have been introduced, but specific measures are still lacking. In this regard, this study proposed plans for building construction curriculum operation applied with team-based learning, building construction course operation applied with team-based learning, and building construction course grade evaluation applied with team-based learning. It is expected that the proposed operation plans can be used in educational settings where team-based learning is to be applied in a changing class environment.

건설 프로젝트의 특성 상, 예측하기 어려운 리스크 인자에 노출되기 쉽고, 다양한 이해관계자들이 함께 동일 프로젝트를 수행하는 과정에서 발생하는 분쟁이 주요 리스크 인자로 인식된다. 다양한 분쟁은 주로 클레임 제기, 조정, 중재, 그리고 소송으로 나타나며 막대한 비용과 시간의 손실을 초래할 수 있다. 따라서 국내 건설기업의 건설 프로젝트 수행과정에서 발생하는 클레임, 분쟁의 유형과 원인을 도출하고, 각 원인의 영향도 분석을 통해 클레임, 분쟁관리에 대한 적극적인 대비가 필요하다. 본 연구는 국내 건설프로젝트에서 발생한 클레임, 분쟁 판례를 수집하여 유형과 원인에 따른 빈도와 영향도를 정량화 하고, 중요도 분석을 통해 주요 클레임 원인을 도출하였다. 도출된 주요 클레임 원인은 공사변경, 상대방의 부당한 행위, 공사 지연에 관한 클레임으로 해당 클레임 원인이 발생할 경우 클레임 비용에 대한 예측을 회귀 모형화 하였다. 주요 클레임 원인별 영향도 예측 결과 공사변경의 경우 전체공사비의 16.1%, 상대방의 부당한 행위는 전체공사비의 5.7%, 공사 지연은 전체공사비의 2.7%로 발생하는 것으로 분석되었다. 본 연구결과를 통해 국내 건설산업의 주요 클레임 요인을 도출하고, 클레임 비용을 예측함으로써 보다 적극적인 클레임 대비에 활용 될 수 있도록 하였고, 더 나아가 국내 건설기업의 프로젝트 관리 역량 평가 및 향상에 기여하고자 하였다.

The construction industry highly depends on each specialized manager which is essential to successful project. However, a new employee, who has just graduated from architectural engineering college, is requested additional education for 1~2 years such as On-the-Job-Training (O.J.T) to perform his/her professional job in construction site. It is wasteful for both construction company and the employee in terms of time and cost. The purpose of this paper is to investigate the required abilities and analyze the gap of demanded abilities between field managers and students. To collect data for analysis, questionnaire which uses Likert Scale has been performed to both parts. As a result, the analysis show that the graduate's abilities related to field experience get especially low degrees in compare with non-field experience factors. These results will contribute architectural engineering education in college to make more realized.

The project performances can be measured in terms of meeting the project schedule, budget, and conformance to functional and technical specifications. Numerous studies have been conducted to examine the causes and effects of change orders for both vertical and horizontal construction, respectively. However, these studies mainly focus on a single project type, so this paper examines the impact of change order for cost growth and schedule overruns using four different building types to close the gap in the change order research area. A total of 211 building projects are collected from four building types: healthcare, residential, office, and education. Statistical analyses using ANOVA tests and linear regression models are used to examine the created metric $CO/day on the cost and schedule impacts. The results found that mean $CO/day values were not statistically different among building types, and that the sum of change orders is a statistically significant predictor of $CO/day. The results will help project stakeholders mitigate the negative change orders effects can be a challenge for project managers and researchers alike.
