건설산업은 불확실성이 높은 산업으로 이에 따른 비용효용성 향상 및 경쟁력 강화를 위한 연구가 다각적으로 진행되어 왔다. 린 건설의 대표적인 요소기술인 라스트플래너 시스템은 기존의 상의하달식 의사결정체계를 개선한 하의상달식 접근방식으로서, 모든 참여주체가 함께 중 단기 공정계획을 검토 시행하는 체계이다. 이와 같은 린 건설은 최근 들어 건설프로젝트에서 주도적인 역할을 하고 있는 발주자의 적극적인 참여와 전체 생애주기를 총괄할 수 있는 리더역량을 요구하는 방향으로 논의가 전개되고 있다. 그러나 발주자가 참여하는 린 건설이 성공하기 위해서는 건설주체 상호간에 요구하는 니즈(needs)수준과 이를 개선하기 위한 전략들이 우선적으로 고려되어야 한다. 본 연구에서는 건설 시공과정에서의 참여주체 니즈 요소를 규명 분석하고, 중점관리항목과 이들 항목들의 개선가능성을 도출하는 방법, 그리고 이를 기반으로 한 발주자 참여형 린 건설 협업 모델을 제시하였다.

Purpose: The purpose of this study is to identify the impact of conflicts and cooperation on project performance in the nuclear power plant construction project, thus contributing to the successful performance of project participants and the achievement of project objectives. Methods: This study used a method of conducting a survey of participants in the nuclear power plant construction project and verifying the hypothesis statistically. Results: The results of this study are as follows; First, role conflicts and relationship conflicts have negative effects on collaboration. Second, role conflicts have a negative effects on project performance, but conflict in relation has no significant effects on project performance. Third, collaboration has a positive effects on project performance. Finally, the communication quality in the relationship between conflict and collaboration has been shown to have a Moderated effect. Conclusion: In order to achieve the goal in the nuclear power plant construction project, the level of collaboration should be improved based on conflict management among project participants.

The main purpose of this study was to examine relative effects on safety behaviors between global feedback and specific feedback at a construction site. Participants were 30 full-time workers at a construction site. Five safety related behaviors were identified as critical behaviors. An ABCB within-group design was adopted. After baseline (A), participants received global feedback on their average percentage of all five target safety behaviors (B). In the next phase, participants received specific feedback on the percentages of individual target behaviors (C). In the final phase, the global feedback condition was reintroduced (B). Results showed that both global feedback and specific feedback were effective in increasing the frequencies of safety behaviors and there were no differences in the effectiveness between the two types of feedbacks.

A large number of employees shifted to Work from home (WFH) due to the COVID-19 pandemic, including the construction workforce. The changes in workload and productivity due to WFH impact the work performance and economic outputs of companies. However, there are mixed results about the impacts of WFH on workload and productivity. In particular, limited studies focused on specific types of work of different occupations in the construction workforce. This study aims to explore the impacts of WFH on workload and productivity considering different types of work for the construction workforce in the U.S. After identifying three main occupations and five types of work, an online survey (N = 69) was distributed. Descriptive analysis showed that participants had less workload (0.82 hours/week) and lower productivity (9.69%) during WFH. Three occupations had varied changes due to the different types of work. Analysis of Variance (ANOVA) indicated that there was no significant difference in workload, while productivity was decreased during WFH. In particular, the productivity of project-related work and communication and documentation decreased significantly. Overall, participants finished 2.85% less workload per week during WFH. The findings provide an insight into WFH in the construction workforce, which improves future remote or hybrid work arrangements in the construction industry.

최근 건설 프로젝트의 규모가 커짐에 따라 건축, 구조, 기계, 전기, 토목, 조경 등 각 엔지니어링 분야의 참여자가 증가하게 되었고, 다수의 참여자들 사이의 의사소통과 정보교환을 관리하는 협력설계관리의 필요성이 제기되고 있는 실정이다. 이에 설계프로젝트 참여자들의 역할 및 업무가 설계단계에서 발생되는 정보의 종류와 시기를 파악하고 국내 설계 사무소의 협력설계 관리현황을 살펴본다. 이를 토대로 설계자와 엔지니어들의 일반적인 업무수행과 의사결정을 지원하고, 설계변경이나 공종별 Interface 간섭시 즉각적인 문제해결을 가능하게 하는 설계사무소와 엔지니어링 업체간 지속적 정보교환관리 시스템의 개발 방향을 제시한다.

The Korean government makes an effort to raise the competitive power of nation through CM activation in the construction industry. Since the first CM service was applied to the atomic power plant project in 1986, the number of CM contracts are continuously being increased and will be up to 20% by 2002 in public sector. However, the public projects had been executed without any procedure manual or standard guideline of CM services. Meanwhile the Ministry of Construction and Transportation issued $\ulcorner$CM Service Guide$\lrcorner$, but the guide shows an indefinite description in the responsibility, authority and scope of activity for the project participants. Therefore, it is required the procedures be improved and scope of activities be established for the project participants. This study was generated from the comparative analysis of $\ulcorner$Standard CM Services and Practice$\lrcorner$ Published by CMAA and domestic $\ulcorner$CM Service Guide$\lrcorner$ and the case of Incheon International Airport construction. The purpose of this study is to provide the fundamental data for an improvement in the procedures of project execution and the construction manager's activities/rolls shown on $\ulcorner$CM Service Guide$\lrcorner$

Disputes seem to be synonymous with large-scale construction projects in Ethiopia. The purpose of this study is to determine the factors responsible for impacting the performance of Ethiopian public construction projects. To this end, 35 success and failure attributes responsible for impacting the performance of the projects were identified and presented to Ethiopian construction professionals in the form of a structured questionnaire, and responses were collected. The factor analysis conducted on the success and failure attributes influencing no-dispute performance separately resulted in six success factors and five failure factors. Further analysis using stepwise multiple regression indicates that owner competence and interaction among project participants have a positive impact on no-dispute performance. However, conflict among project participants has a negative impact on the no-dispute performance of Ethiopian public construction projects. Although Ethiopia-specific, the results reflect construction management problems common to both developed and developing countries. The findings are expected to help researchers and practitioners gain a better understanding of critical success and failure factors and to help them take proactive measures to avoid disputes in public construction projects.

철골공사 참여자들은 문서를 통해 다른 참여주체와 다양한 정보를 교환한다. 현재의 철골공사 업무체계는 다단계 도급의 형태를 가지고 있어서 참여주체들 간에 문서를 통하여 신속하게 정보를 교환하는데 있어 많은 어려움을 가지고 있다. 따라서 여러 주체가 관련된 설계변경과 같은 문제점이 발생했을 경우 업무처리에 많은 기간이 소요되며 관련 주체들 간의 협의가 불충분해질 우려가 있다 본 연구에서는 현재의 철골공사 설계변경 업무프로세스를 체계화하였으며, 철골공사 참여자들이 신속하고 정확하게 설계변경 업무를 처리함으로써 성공적인 철골공사 관리가 가능하도록 하기 위하여 현행의 설계변경 업무 프로세스에 XML을 적용하여 프로세스를 개선하고, XML지반 철골공사 업무지원시스템(XCOS)을 개발하였다.

건설 프로젝트는 기획, 설계, 시공 등 전 과정이 많은 프로세스를 거쳐 수행되며, 각 프로세스에는 발주자, 시공자, 감리자, 공공기관, 협력업체 등 많은 관련주체들이 참여한다. 이들의 효율적인 문서교환을 통한 상호협력은 원활한 공사수행과 나아가 프로젝트 성공의 중요한 요소이다. 건설프로젝트 참여주체간 문서교환을 웹을 통해 효과적으로 하기 위한 노력이 이루어지고 있으며, 그 수단으로 XML/EDI가 부각되고 있다. 본 연구의 목적은 웹기반 XML/EDI를 활용하는 건설프로젝트 참여주체간 문서교환 모델에서 문서정보의 관리를 위한 데이터모델의 구축이다. 본 연구에서는 XML/EDI로 교환되는 문서정보를 데이터베이스로 모델링하는 방법을 제안하고 데이터베이스에 저장된 문서정보가 활용되어지는 개념을 설명하였다. 문서정보간의 연계성을 파악하여 프로젝트 문서를 분류하였으며, 실제적인 모델링 예를 제시하였다.

Construction and engineering is one of the world largest industry. Yet, it Is one of the most inefficiently operated industry. Since buildings are not constructed by mass production, construction projects usually require intense communication and collaboration between participants, who are usually widely dispersed. That is the main reason for the inefficiency. eWorks21 that we developed in this research, is a project management system that can improve communication and collaboration among project participants using the Internet. eWorks21 can reduce project life-cycle, costs, and increase revenue, resource utilization, controls, transparency, and competitiveness, which will eventually provide infrastructure for knowledge management of construction projects. In this research, we classified currently available project collaboration systems, and analyzed the benefits gained by using project collaboration systems. Then we describe the implementation of eWorks21, and discuss employment and utilization strategies of project collaboration systems.
