Global competition and reduced project life cycle ultimately puts greater performance requirements on the capital project delivery systems used to maintain competitiveness. Despite continuing improvements in delivery cycle time, business owners of facilities continue to demand greater improvements in project delivery cycle time. Therefore, it is very important to investigate the various techniques and methods leading to reduction in project cycle time and also identify the applicability of identified techniques and methods. This paper introduces reduction techniques identified through literature review (i.e, Schedule Reduction Techniques (SRTs), Management Techniques (MTs), and Construction Institute Industry (CII) Best Practices (BPs). In order to collect applicability of these techniques under different project phases (Pre-project planning (PPP), Design (D), Material Management (MM), Construction (C), and Start-up (SU)), the Essence Applicability Matrices (EAM) is used.

This study aims at giving the framework to estimate the environmental load at planning and schematic phase. With increasing awareness of environmental issues, the effort to reduce the environmental impacts caused by human activity has been increasingly enlarged. So far most of researches estimating CO₂ emissions have analyzed energy consumption based on BOQ (Bills of Quantity) acquired after detailed design. There is also lack of reliability in the estimated environmental impact using the basic unit of a facility at the planning stage, because it uses a limited specific section of historical data. Thus, this study is targeted at developing framework to assess reliable environmental loads based on information available at project early phases by making case-bases from historical design information on PSC Beam Bridge. Historical database is built on the basis of the LCA (Life Cycle Assessment) and in order to set input information for estimating model, the literature about information in an early project phase are reviewed. Using the information available in the planning and schematic design stage, the Framework is presented to estimate the environmental load in an early stage in the project. Developing an environmental load estimation model in accordance with the Framework presented in this study, it is expected that the environmental load in the initial project phase can be estimated more quickly and accurately.

The aim of this study is to establish resident-participative primary design of integrated rural development project with master planner by setting principals of open competition and transparent decision-making about village-to-village or business-to-business unit enterprise in Onui area, Hong-seong Gun. For effective processing, software projects such as residents education and rural landscape planning are simultaneously conducted for enhancing project understanding and comprehensive development plan including related post project. Above all, competition teams for individual project were organized to establish the resident-participative primary design using survey tables of residents demand. In 6 months resident-participative processing of primary design, continuous education and visiting to advanced area are conducted in team unit. Strengthened ability of team unit can be used in management and maintenance after project development. To do this, residents with the same opinions gathered as one competition team and identified business plans such as village asset, business location, size, program, and method for land securing. Favorable decision-making process by residents who are audience in project presentation of competition team has conducted. After selecting competition teams, continuos consulting are operated for establishing operation and management for developed or remodeled facilities through repetitive education and visiting advanced area. In this process, unit project suggested by competition team are completed. Preliminary selection was conducted by experts who were entrusted by residents. After residents agreement of project main stream such as major facilities and location, final detailed cost of projects are work out. Suggested process in this study which choose the final project by residents would improve residents' voluntary participation in integrated rural development project through open competition in establishing primary design.

Risk management at an early stage of projects is known as an effective method expected various benefits. The PDRI(Project Definition Rating Index) by the CII(Construction Industry Institute) is defined project scope for reducing risks. In addition, the PDRI is one of the verified methods for achieving benefits by a risk management. The literature review in Korea about risk management is all about focusing on construction works and the construction phase. Thus, we need to extend the perspective of a project management such as the PDRI. To develop the Korean PDRI, However, we have to consider Korean situations. Therefore, in this study, we analyze some previous studies of PDRI' indexes and its using methods, and suggest the new direction for using PDRI in Korea. This method will enable to improve the scoring method of a project management with PDRI in Korea.

Construction duration is very important as a factor which comprises three axises of construction management with quality and cost in construction project. In general project condition, construction duration is optimized while minimizing construction cost and securing required quality. However, in case of insufficient project time duration or delayed projects, project progress management is different from those of normal projects. These project areas need solutions to complete work within a given completion day. To time shortening the current duration of each typical floor of structural framework in apartment construction is investigated, and a basic time schedule planning for typical floor of structural framework in normal projects is planned. This study proposed 3 ways for time shortening of urgent project or insufficient construction duration project. Also, This study proposed detailed time shortening method and technical solution conditions while time is shortened.

Recently the complexity and difficulty of the IT projects are increasing due to technological and environmental risks, resulting in the adoption of PMO(Project Management Office) onto IT project management practices, including public area projects. For example, the Korean government regulated the application of PMO onto large scale public IT projects. However, since there has been no reliable method to estimate the cost to execute PMOs, a PMO cost evaluation model to support the budget and cost planning of PMO projects is required. Thus, the purpose of this research is to develop a systematic cost evaluation model for PMO projects. We identified the dimensions that determine the PMO execution cost to be the scale of the subject project, the technical difficulty level of the subject project, and the tasks to be executed in the PMO project. Based on the determinants, the PMO execution cost model were developed from historical data and experts opinion. Upon verification, the validity of the developed model has high level of consistency compared with their experiences of real PMO project costs.

해외 플랜트 건설시장에서 국내기업의 기술적 위상은 크게 향상되었으나 기술적 측면에 비해 프로젝트 관리 측면의 역량은 미비한 수준으로 평가되고 있다. 프로젝트 관리 중 프로젝트 수행 초기인 기획단계에서의 사업관리 역량은 선진 건설 기업의 핵심 역량으로 볼 수 있으며, 그 중 초기 원가산정 기술은 국내 기업의 역량 향상이 시급하다. 본 연구에서는 플랜트 프로젝트 기획단계에서 진행되는 개산견적 방법론에 대해 조사 및 분석하고, 사례분석을 통해 개산견적 방법을 제시하였다. 기존의 개산견적 방법론 중 비용지수법과 변수견적법의 로직을 토대로 플랜트 프로젝트에 특화된 입출력 변수를 도출하여 개산견적 도구를 개발하였다. 제시된 방법론의 유효성은 사례 프로젝트의 개산견적 금액과 실적 프로젝트 금액 간의 정확도 비교를 통해 평가하였다. 개발된 플랜트 개산견적 방법론의 활용성 증대를 위해 실적 프로젝트의 체계적인 데이터화가 필수적이다. 향후 프로젝트 원가산정의 정확성을 높이는 것은 기업의 프로젝트 수주 및 수익확보와 직결되므로, 개발된 도구의 적극적 활용이 기대된다.

소프트웨어 프로젝트 계획은 각 작업의 공수를 예측하고, 적절한 인력을 할당한 뒤 일정을 산출하는 과정을 포함한다. 프로젝트의 규모가 커질수록 가능한 개발 계획의 경우의 수가 많아지기 때문에 관리자가 합리적인 결정을 내리기 어렵다. 이를 지원하기 위해 프로젝트 계획 생성 기법들이 제안되어왔다. 제안된 대부분의 기법들은 전체 프로젝트 일정의 최소화를 계획 생성의 가장 중요한 목표로 사용한다. 하지만 일정 최소화를 달성하는 계획은 개발되는 소프트웨어의 품질을 고려하지 못하기 때문에 이러한 부분을 함께 반영한 프로젝트 계획 생성이 필요하다. 본 연구에서는 합리적인 프로젝트 계획을 생성하기 위하여 소프트웨어 프로젝트 계획에 따른 소프트웨어 품질 점수를 정의하고 동시에 전체 일정 목표를 고려할 수 있는 프로젝트 계획 생성 기법을 제안한다. 관리자는 본 기법을 사용하여 전체 소프트웨어 개발 프로젝트에 요구되는 기한 안에 해당 소프트웨어의 품질을 최대하는 계획을 생성할 수 있다.
