EPC contractors have made continuous efforts to develop integrated project execution methods to improve the performance of industrial plant project. In particular, the concept of Advanced Work Packaging (AWP) has been recently presented by readjusting the existing "Work Packaging" concept as part of the integrated project execution method from the project life-cycle perspective. However, Korean EPC contractors are still unfamiliar with the AWP implementation. Thus, this study aims to identify the organizational competency factor for effective implementation of AWP. For this purpose, first, this study identified the expected risks in AWP project and the 29 organizational competency factors to manage risks. Second, five experts verified the suitability of factors and supplemented the factors. Finally, 37 factors were identified as organizational competency factors for implementing AWP.

Recently, the design-build delivery system is being generalized in domestic construction project. The design-build system is becoming an increasingly preferable alterative to design-bid-build delivering method. In design-build project, however, a large construction company and design firm make up consortium as a design-build contractor rather than single company performs design and construction work. In this case, usually the construction companies take a leading role but due to their lack of managerial know-how in the design-build system, they could miss the merits of this approach. Therefore, it is necessary to investigated throughly the function and information flows all over the design-build project. In this research suggests a process model and database in the whole phase of design-build project. This process model and database system will also support to Improve the consistency of functional process and minimize incoherent activities in each phase of design-build project.

최근 일본에서는 ESCO사업에 PFI법을 새로이 적용하고 있다. 성과배분제, 성과보증제에 이어 이 제도를 적용할 경우, 국가 및 공공기관을 대상으로 하는 ESCO사업의 확대 및 자금조달이 한층 유리해질 전망이다. 지난 99년 제정된 PFI(Private Finance Initiative)법(민간자금 등의 활용에 의한 공공시설 등의 정비 등의 촉진에 관한 법률)에 근거한 사업은 ''공공시설 등''에 있어서 건설, 유지관리 운영 등을 민간의 자금, 경영능력 및 기술적 능력을 활용하는 사업방법으로 사업 전체의 리스크관리가 효율적으로 행해지는 것과 설게$\cdot$시공$\cdot$유지관리$\cdot$운영의 전부 또는 일부를 일체적으로 취급하는 것에 의해 사업비용의 절감이 기대되며 질 높은 서비스의 제공이 가능한 제도이다. 이것과 매우 유사한 개념을 가지고 있는 것이 성과보증제에 의한 ESCO사업이다. 민간사업자인 ESCO사업자가 자금을 조달하고 에너지절약 개수공사에 따른 설계$\cdot$시공$\cdot$, 운전$\cdot$유지관리, 계측$\cdot$검증, 에너지절감 보증 등의 서비스를 제공하며, 광열수도비 및 운전$\cdot$유지관리비의 절감분으로 모든 투자와 ESCO사업자의 경비를 지불한다. 또 에너지절감 및 공공의 이익보증을 포함한 퍼포먼스계약이라고 하는 형태를 취하는 것으로 공공 이익의 최대화를 도모함과 동시에 금융기관의 투자 리스크에 관한 우려를 회피할 수도 있다. 또 PFI법 특유의 법제상, 재정상의 조치와 재정상 및 금융상의 지원이라는 배려에 있다. 예를 들면, 국고채무부담행위의 설정, 행정재산 사용료의 무상화 또는 감면, 프로젝트 파이낸싱 등에 의한 자금조달을 고려할 경우에 있어서 담보권의 설정 등에 관한 제도를 합리적으로 정비하는 것이 가능하게 된다. 그 내용의 대강을 살펴본다.

The factors of uncertainty such as work delay could cause many problems, for example, increase of construction cost and terms of work, and the deterioration of quality. Because of these, the uncertainty risk is regarded as an important management factor to obtain the success of construction project. So, the systematic management plan about the uncertainty factors is needed because it plays an important role in the completion of entire project. And also analysis of some factors which can cause the work delay can be one way of improving construction project's certainty and making it competitive. In this reason, we have to make an effort to set a priority based on analysis of quantitatively numerical value about work delay factors to manage them effectively. Thus, this study aims to suggest the basic data for the effective management and prevention of work delay in steel-frame work which is progressive actively now, along with increasing of demand of high-rise buildings by analyzing each reasons of work delay factors and also by suggesting important management factors that are coded according to each construction work using FMEA method which could give a data about the importance of work delay factors through quantitatively numerical value.

EPC plant projects are large and complex, requiring systematic working methodologies, accumulated data, and thorough planning through communications between the entities. In this study, the method of extracting the process planning information using asset data of the plant project and using it to present the initial process plan is presented through the concept of IAP(Interactive Planning). In order to carry out the effective IAP at the early stage of the project, this study extracted the schedule element information from the asset data, created the process plan for each work package, and applied it to the sample project case. Through the proposed IAP methodology, it is possible to promote the utilization of asset data, to identify schedule risks, and to develop countermeasures, which can form the basis for establishing the process management strategy to successfully complete the project.

The demand of construction risk analysis is rapidly increased to improve the competitiveness of construction companies and the sound management of the construction project. However, estimating the amount and uncertainty of the risk is difficult due to the wide range of risks in the construction industry. Moreover, most of the research on risk management of construction risk is only focused on the causes of risk without separate the internal and external risk. This study statistically analysis the internal risk and external risk based on the accidents cases which are caused at construction sites to define the difference and importances of the risk. An accident cause analysis and T-test analysis are carried out to reach the goal of study. The results of the study are expected to be used as a guideline of construction project risk analysis.

As the CM at Risk market grows recently, designers and CM companies that have been performing agency CM services have been showing their interests to participate in the CM at Risk projects. With the assumption that agency CM companies with a lot of experiences and know-how in the field of construction project management have created the circumstances to enter the CM at Risk market, this study investigates the competencies necessary for the agency CM companies to carry out the CM at Risk projects. The compentencies to run the CM at Risk projects were identified based on the literature review. A survey was conducted to identify the competencies that need to be supplemented first. The survey results revealed that competency related to partner companies, finance and guarantee, risk and claim, and project cost were identified to have a higher level of complementation compared to other competencies. In addition, considering that the level of competency that need to be secured is high, as the level of holding of all competency is on average 76% of the required level, in the beginning, small-scale CM at Risk projects with relatively low risk are mainly carry out, strengthening competency and then increasing the scale is considered more appropriate strategy.

Schedule delays present a major risk factor, as they can adversely affect construction projects, such as through increasing construction costs, claims from a client, and/or a decrease in construction quality due to trims to stages to catch up on lost time. Risk management has been conducted according to the importance and priority of schedule delay risk, but quantification of risk on the depth of schedule delay tends to be inadequate due to limitations in data collection. Therefore, this research used the BERT (Bidirectional Encoder Representations from Transformers) language model to convert the contents of aconstruction log, which comprised unstructured data, into WBS (Work Breakdown Structure)-based structured data, and to form a model of classification and quantification of risk. A process was applied to eight highway construction sites, and 75 cases of rain schedule delay risk were obtained from 8 out of 39 detailed work kinds. Through a K-S test, a significant probability distribution was derived for fourkinds of work, and the risk impact was compared. The process presented in this study can be used to derive various schedule delay risks in construction projects and to quantify their depth.

In recent, many Korean contractors have tried to extend their business area into the overseas construction market, mainly as a result of a reduction in their domestic construction market. However in terms of risk, overseas construction projects are likely to face a number of unpredictable problems, many of which occur as a result of differences in contract cultures and construction environments between Korea and other countries. One key issue facing overseas construction projects in particular, is that of sub-contracting and control, and the way in which many countries of Commonwealth of Nations operate a unique subcontracting method well known as a nominated sub-contractor(NSC). This paper introduces the NSC system and differences as comparing among standard construction contract forms, such as JCT, SIA, HKIA and PAM. in UK and Asian Commonwealth of Nations. Also, we attempt to classify the type of the NSC system through the consideration of NSC clauses in accordance with the objection and termination of NSC contracting respectively.

As a project progresses, it is well known that construction manager has to define the contingency for the expected project cost, which is used as a buffer for uncertainty. In this study, we mention uncertainty as the amount of likelihood that is difficult or impossible to predict project cost. From the completed work package, we obtain the true cost value, and this information is technically good data for estimating the realistic contingency of work packages to be accomplished. Based upon this historical information, construction manager recomputes the contingency for the remaining works. Conditional probability theory is often useful for re-estimating one of the remaining project progress as the true cost of the completed works can be different from the planned cost. As a project is progressing, true value is really important to predict the realistic project budget and to decrease the uncertainty. In this study, we gave applied conditional probability theory to estimating project contingency supposing a project that consists of fire work packages, provide the fundamental framework for setting and controlling project contingency.
