건설 프로젝트 단계별로 생산되는 다양하고 방대한 정보에 대한 효율적인 관리와 정보의 상호 교환 및 공유는 건설 산업의 생산성을 좌우하는 중요한 요소이다. 최근 건설 정보 통합에 대한 관심이 높아짐에 따라, 기획, 설계, 시공, 유지보수 등의 프로세스 및 엔지니어링 어플리케이션 간의 정보 통합에 대한 연구가 수행되고 있다. 하지만 BIM(Building Information Model)과 같은 정보 모델을 활용하여 정보를 통합 관리하는 것에 대한 연구는 상대적으로 건축 분야에 집중적으로 이루어지고 있다. 따라서 토목 분야에서 프로젝트 정보의 통합적인 관리와 업무 프로세스 별 엔지니어링 어플리케이션 간의 교환 및 공유를 위한 통합관리 시스템이 필요하다. 본 연구에서는 토목 프로젝트 통합 관리 시스템 구축을 위하여 토목 프로젝트 정보를 담을 수 있는 정보 모델을 설계하고, 토목 구조물 가운데 교량을 대상으로 하는 토목 프로젝트를 정보 모델에 적용해 보았다.

본 논문에서는 토목 프로젝트를 효과적으로 수행하고자 개발된 CPLM(Construction Project Lifecycle Management) 시스템을 현재 진행 중인 교량 건설 프로젝트에 적용함으로써 실제 토목 프로젝트의 전주기에 걸쳐 CPLM 시스템의 활용 가능성과 효율성을 검토하였다. 테스트베드 대상은 ${\bigcirc}{\bigcirc}{\bigcirc}$대교의 Ramp A 구간과 주경간 교량의 주탑이며, 적용 절차는 대상에 대한 정보 모델을 구축하고 CPLM 시스템을 통한 참여 조직간 협업을 수행함으로써 시스템의 효율성 및 활용성을 도출하는 과정으로 이루어졌다. 본 연구를 통해 보다 효과적인 토목 프로젝트 관리를 위한 CPLM 시스템의 개선안을 도출하고, 토목 프로젝트의 효율적 수행을 위한 방향을 제시하였다.

Due to harsh conditions of construction site, understanding of current feature of terrain and other infrastructures is critical issue for site managers. However, because of difficulties in acquiring the geographical information of the construction sites such as large sites and limited capability of construction workers, comprehensive site investigation of current feature of construction site is not an easy task for construction managers. To address these circumstances of construction sites, this study deduce difficulties and applicabilities of unmanned aerial vehicle in the area of construction site management. To confirm applicability of UAV in civil construction project, case study have been conducted on the road construction project. The result of case study proved that the developed system is one of promising technologies that has been studied in construction site management. To improve applicability of UAV for construction and process management information, law and technical issues will be an important area of future study.

Risks in construction projects are increasing remarkably due to recent changes in the construction environment. Active risk management is required to recognize risks as opportunities. The purpose of this study is to propose a risk management model of the importance determination method through comparative analysis using Kano model, Timko CSC (Customer Satisfaction Coefficient), and ASC (Average Satisfaction Coefficient). Based on previous studies, the validity of risk management factor determination is reviewed through a questionnaire modified Kano model through interviews with working-level workers using the Delphi technique. Through this, a suitable risk management model is presented by selecting key risk management factors recognized by domestic construction project practitioners. As a result of the study, the Kano model developed to verify risk management of construction projects was evaluated to be effective in verifying the risk management of practitioners. It is expected that the Kano model presented in this study will be actively used to verify the importance of risk management for construction projects.

본 논문에서는 BIM의 기술 중 하나인 DMU(Digital Mock-Up)을 실제 프로젝트에 적용하여 업무 효율에 기여한 결과를 소개한다. 삼성물산 건설부문의 경우 DMU는 건설 프로젝트의 입찰단계 및 시공계획 단계에서 적용되어 많은 성과를 거두었다. 입찰단계의 경우 대상 프로젝트의 교량, 터널 등의 구조물을 실제와 같은 지형조건 및 설계 조건으로 모델링하여 프로젝트의 개요 파악, 정보의 공유, 선정된 공법의 효과 분석 등에 적용하였으며 시공단계에서는 주로 복잡한 구조물의 철근 간섭 검토 및 효율적인 배근 방법 분석을 위한 도구로 사용되었다. 적용결과 공기단축, 원가절감, 시공성 향상에 기여하였으며, DMU는 향후 프로젝트 관리도구로 통합되어 구조물공사의 원가절감 및 생산성 향상에 기여할 것으로 예상된다.

Differing from civil engineering and construction, landscape architecture projects are far from efforts in operation and project management. Under the circumstances, it is worthwhile to adopt scope definition from project management for construction and civil engineering in some respects. First, scope definition is able to be conducted through a simple procedure without additional investment in capital and time. Second, the output produced by scope definition is very substantial. The research scrutinized scope definition procedures accompanied by landscape architecture project execution and derived various methods in order to help scope definition for efficient landscape architecture projects. Based on the literature review, a design case study, and an exert interview, the project success elements were developed consisting of 3 sections, 8 categories and 50 elements, grounded on the theoretical base of PDRI. The elements are expected to pave a way to an adequate level of scope definition among participants of landscape architecture projects and contribute in efficient project execution.

This study aims to prove the importance and necessity of a project management consultancy (PMC) that systematically manages construction projects to ensure their successful implementation. In order to analyze the interrelationship between the role of PMC and the outcome of the construction projects, structural equation modelling(SEM) was conducted. Hence, one of the critical aspects when conducting the project, human resource competency, especially referring to the competency of project team members and the project manager's leadership, affects the performance of construction projects. As a result of this study, PMC is found to have significant effects on human resource competency and construction project performance. In addition,human resource competency also had a significant effect on construction project performance. Consequently, the research outcomes suggest that introducing PMC services should be done when implementing large domestic infrastructure projects successfully, as doing so will enhance PM leadership and strengthen the capacity of the project team members.

Managing mega construction project is a very challenging task due to its large scale and complexity. To deal with the challenge, progress measurement must be estimated reliably and effectively. Many researchers have presented progress measurement methods, but previous studies are limited to single or several types of facilities. Thus, they have difficulties to being applied to mega construction projects that covers multiple facilities. To overcome the limitations, this paper proposes a progress measurement framework considering characteristics of mega construction projects. The framework consists of four phases : development of Work Breakdown Structure, determination of weights of main facilities and sub facilities, and calculation of the integrated progress rate. To validate the proposed approach, a case study of Sejong city in Korea was performed. The results of the case study showed the applicability of the proposed framework and confirmed that it enables to reliably measure progress rate of mega construction projects.

BIM technology, based on 3D model of civil engineering structures, creates and manages information of the structures throughout four stages: Planning, design, construction, and maintenance. BIM is now used around the globe for improvement of the construction productivity. However, in order to expect the efficient engineering work, collaboration system between participants in a construction project is necessary. Therefore, in this paper BIM based CPLM (Construction project lifecycle management) system was designed and developed by analyzing the requirements of participants of a construction project. CPLM system offers an environment which enables the sharing and management of information according to the each stage of construction. CPLM is expected to aid cooperative decision-making during the overall construction process through the process innovation and the efficient data management.

For the success of construction projects, construction companies have begun to recognize the innovation ability of members who participate in projects that can adapt and cope with environmental changes caused by knowledge-based informatization and globalization. The questionnaire of the research selected 254 final valid samples of the members participating in the construction project using online. An empirical analysis of the research model used the structural equation model (Smart-PLS 2.0). The purpose of this study is to investigate the effect of psychological ownership on person-job fit and rewards system in the construction project. First, person-job fit has a positive effect on psychological ownership. Second, intrinsic rewards and extrinsic rewards in the rewards system have a positive effect on the psychological ownership. Third, psychological ownership has a positive effect on innovative behavior. Finally, the mediating effects of psychological ownership were found to have no mediating effect on person-job fit and rewards system. In order to induce innovation behavior, the managers of construction companies need to recognize the importance of psychological ownership and build a model of construction project organization activation through development of person-job fit and rewards program.
