With the booming of construction and property industries in China, the demand for high-rises and mega-scale buildings with more integrated building functions, open- and tailor-shaped outlooks, better connections to municipal infrastructures, and higher grades of building importance has been increasing in the past two decades. The seismic design and engineering of such modern mega-buildings face engineering challenges such as hazard mitigation of extreme actions and surroundings, integrated structural frameworks and building skins, complex connections, and overall construction efficiency. It is the work of a new generation of civil and structural engineers to enhance engineering efficiency and achieve overall engineering, environmental, and economical effectiveness for these high-rise projects. This paper elaborates the above topics through case studies on the design and construction of four such developments in China. Some rethinking is conducted on evolution in modern seismic engineering and design through innovation to achieve an acceptable level of overall sustainability and building effectiveness.

무안기업도시 프로젝트는 투자규모가 기반 조성단계에서만 3조원에 이르는 대형 프로젝트로, 건설사업관리의 성공적인 수행이 사업 성패에 결정적인 영향을 미친다고 할 수 있다. 따라서 본 연구는 무안기업도시 프로젝트의 건설사업관리 수행을 위한 계획을 수립하기 위하여, 핵심과업 수행전략 및 조직구성 및 지원체계를 설정하는 것을 목적으로 하였다. 이를 위해 우선 사업의 개요 및 과업목표에 대한 분석을 하였으며, 사업관리의 필요성 및 프로세스를 살펴보았다. 이를 바탕으로 과업목표를 달성하기 위한 수행전략을 정의, 개발하고, 전략의 실질적 시행을 위한 조직구성 및 지원체계를 확립하였다. 본 연구는 올바른 계획 하에서 사업관리가 이루어질 수 있도록 지원함과 동시에, 향후 대형 프로젝트의 사업관리에 대한 사례로 기능할 수 있을 것이다.

Construction supply chain management (CSCM) has become one of the critical factors that determine the success of a construction project as it becomes increasingly complicated and mega-sized. Particularly for high-rise or mega-sized building construction, just-in-time supply chain management is required due to lack of storage space and effective logistics for construction components and materials at a construction site. Despite the fact that research and development of radio frequency identification (RFID) and wireless sensor network (WSN) technology have been performed, construction project managers still need to carry mobile devices and check material and component flow at each stage of the supply chain process. This research proposes that the equipment used in the construction supply chain process, such as movers, trailers, gates, and hoists, can become main actors in the supply chain process using RFID and WSN technologies. And the proposed equipment and process focused on a solution to the redundancy identification problem, which has been observed in operations that use RFID/WSN-based processes for construction logistics. This paper also presents issues identified through verification and validation of the research results and proposes further studies.

최근 국내 외의 건설업은 대형화 복잡화 되어 메가 프로젝트의 성격을 보인다. 메가 프로젝트는 단순 합의 개념으로는 추구할 수 없는 복합적이고 상호 조율된 가치를 추구하므로, 프로젝트 관리의 관점이 아닌 프로그램 관리 관점에서의 접근이 필요하다. 프로그램 관리는 '종합사업관리'로 볼 수 있으며, 효율적으로 프로그램 관리를 위해서는 종합적인 관점에서 신속하게 의사결정을 지원해야 한다. 그러나 기존의 업무 지원 방법으로는 이를 해결 할 수 없기 때문에 의사결정을 지원해줄 수 있는 도구가 필요하며, 전자매뉴얼이 이 역할을 해줄 것으로 기대된다. 그러나 이러한 장점에도 불구하고 시방서 및 법률 등의 시스템 외부 정보들의 변동성으로 인해서 전자매뉴얼에 대한 연구는 미비한 실정이었다. 그러므로 본 논문은 시스템 외부 정보들과 상호 호환될 수 있는 전자매뉴얼 개발에 대한 연구의 일환으로, 사업수행 과정 분석 결과를 반영한 시스템 프레임을 제시하고 이를 바탕으로 데이터베이스를 구축함으로써 건설분야 전자매뉴얼의 국내 도입에 일조 하고자 한다.

As a recent global trend, the majority of mega-size plant projects are delivered through EPC (Engineering, Procurement and Construction) contracts, where a single contract is awarded for engineering, procurement, and construction. Under this contracting mechanism, it is challenging for contractors to carry out the projects under traditional project management processes used in design-bid-build projects. A new EPC Plant, the POSCO Special Steel Plant in Changwon, was built successfully at the beginning of 2012 and it is currently in full-scale production. The project has encountered a number of major difficulties however, with some technical and managerial issues through its development process. As summarized in this paper, the authors (as project participants with the contractor) investigated it as a post construction analysis and recorded the Lessons-learned for future project management improvement.

As mega-sized and complex building construction projects are increased, the importance of project scheduling and control is emphasized. Project scheduling and control technic is not used widely yet in Korea, but interests in it is progressively increased. By now, most research projects mainly have focused on scheduling issues. Project progress management is also as much important as project scheduling issues. Current state about project progress management in Korea is analysed and way for improvements are suggested in this paper. At first, research projects undergone and practice are analysed and fields experts are survey about current state about project progress management. This study suggests the progress management method for quantitative and qualitative project progress analysis.

The impact of a new stadium on the urban context and regional development is significant. Especially where several new stadiums are built for single mega events like the Olympic Games, Commonwealth Games or the Soccer World Cup the impact is even higher. Objective of this paper is to identify and analyze the key drivers for sustainable integration of stadiums within the existing context. The level of sustainability is analyzed based on four different categories: urban, social, environmental and economics. Particular focus is on the project management strategy for implementation of the key drivers during pre-design, design and execution. In conclusion key elements of the project management strategy for sustainable integration of a stadium within the urban, environmental, social and economic context are summarized.

As a recent global trend, the majority of plant projects are delivered through EPC or EPC-turnkey contracts, where a contractor's liability is more complicated because of the mega size scale and financing method. Previous researches have been lacking a practical usability for project members for liabilities of contracts. Those were focused on solving the claims or schedule calculation issues only. The objective of the present study was to develop a validation process for LDs (liquidated damages) in contractor's liabilities with various case studies and expert judgments. As summarized in this paper, the processes and tools were developed with project life cycle process. The project preparation phase includes 3 step check lists to determine the Go or No-go for projects. In progress phase, contractors should focus on the response strategies for claims with liabilities. The study concludes that those developed processes and tools will help to manage risk of LDs for the contractors in the overseas projects.

대규모 복합 프로젝트(complex project) 또는 메가 프로젝트(mega project)들에서 확률적으로 공정계획을 수립하는 대표적인 방법이 PERT (Project Evaluation and Review Technique)기법이다. PERT기법은 작업공기의 불확실성에만 중점을 두고 작업간 연결관계는 Finish-to-Start(FS)관계로 제한되기 때문에 작업간 중복관계가 존재할 경우 작업간 연결관계의 불확실성에 대한 확률적인 추정이 불가능하다. PERT기법의 이러한 한계를 극복하기 위해, 작업간 다양한 중복관계들의 불확실성을 고려하여 사업전체 공기를 추정하는 방법으로 PLET (Probabilistic Linkage Evaluation Technique)기법을 제안되었다. 그러나 PLET 기법에 의한 사업공기 추정은 작업간 연결관계의 불확실성만을 고려할 뿐, PERT기법에서의 작업공기에 대한 불확실성은 고려하지 않으므로, 완전한 사업공기 추정방법이라 할 수 없다. 본 논문은 작업공기의 불확실성을 고려하는 PERT기법과 작업간 연결관계의 불확실성을 고려하는 PLET기법을 결합시켜 사업공기를 추정하는 통합 모델을 제안하고 확률적 타당성을 검증한다. 그리고 통합 모델의 일정계산방법을 제시하고 이를 실제사례에 적용하여 검증함으로써, 고위험 건설사업의 공정계획을 수립할 때 보다 폭넓고 다양한 위험요인들을 통합적으로 고려하는 확률적 사업공기 추정 방법을 제안하는 것이다.

Recently, the researches on the urban regeneration projects have been performed very actively. It is a part of the effort that solves some social and economical problems occurred by deteriorated buildings and degraded infrastructures through new urban regeneration projects or redevelopment projects. However, the urban regeneration projects show the characteristics that can not guarantee in the project performance because the projects have various and complex stakeholders related to these projects and are exposed to lots of risks due to its huge scale. This study proposed the risk performance index method to improve the efficiency of the overall performance measurement for a mega-project by extending from the traditional cost/schedule based performance measurement system. The risk performance index method proposed in this study has a similar system to the EVMS, and makes possible to perform a three dimensional integrated performance measurement in cost/schedule/risk through 18 different indexes that compose the risk performance index.
