국토해양부는 공공공사 건설근로자에 대한 임금체불을 방지하기 위해 '건설근로자 노무비 구분관리 및 지급확인 지침'을 마련하고 지난 1월 1일부터 시행에 들어갔다. 이에 따라 공공건설공사 현장의 원수급인은 매월 하수급인이 고용한 근로자를 포함한 모든 건설근로자의 실제 근무내역을 작성해 발주자에게 노무비를 청구해야 한다. 또한 발주자는 원 하수급인이 건설근로자에게 실제 지급한 임금 지급내역을 확인한 뒤 같은 달 청구된 노무비를 지급하고, 이어 원수급인은 하수급인의 노무비 전용통장으로 이를 지급해야 한다. 아울러 발주자와 원수급인은 '노무비 알리미 서비스'를 통해 노무비 지급 사실을 해당 건설근로자에게 문자 메시지로 통보함으로써 임금지급 절차가 진행되고 있음을 사전에 근로자들에게 알려줘야 한다.

우루과이라운드 협상에서 건설시장개방은 건설서비스로서 일반시장개방과 정부조달과 관련된 공공건설발주시장개방의 두 측면에서 이루어졌다. 정부는 건설시장과 함께 국내 건설관련 제도들을 계속해서 개선해 오고 있다. 제도 개선의 초점은 입찰, 면허제도 등과 같이 외국업체에 대한 영업자격부여방안이며 그밖에 감리제도 등도 부실공사방지대책과 맞물려 개선이 이루어지고 있다.

The government and local governments are utilizing regulations, policies, and various project management techniques at each project stage to effectively and systematically manage public construction projects. However, the increase in construction costs continues to occur. In order to solve these problems, this study attempted to collect cases of existing public construction projects and analyze historical data. And it would like to derive the impact factor of increased construction costs. Based on the results, a plan was proposed to prevent the causes of increase and minimize in construction costs. The main reasons for the increase in costs were the occurrence of civil petition, differences between design documents and site conditions, and changes due to requests from the owner and changes in the business plan. And to solve these problems, this study proposed improvement for each cause from an institutional perspective, along with interview with experts and project owners. The results of this study are significant in improving the process of existing public construction process and presenting key inspection and review items for each major inspection stage in order to solve problem resulting from the analysis of the performance of public construction projects.

With the current trend in the industry toward increasingly complex, diversified and large construction projects, advanced countries in the construction field have already introduced and applied a variety of methods for placing orders in order to cope with such changes in construction circumstances. In Korea, there have been efforts to continuously improve approaches to placing an order. With the aim of diversifying the methods of Delivery Systems, the "Technical Proposal Type Bid," and the "Design Competition and Technical Proposal Type Bid" were introduced through a revision of Korea's contract law enforcement ordinance. In line with the government's efforts, criteria for a method of placing an order that is suitable for a public construction project should be presented. This study enumerates the current issues using a survey for construction projects already placed and an analysis of the current status, and presents the selection criteria for Delivery Systems by business type as an improvement for the problem.

Construction accident rates are reflected in the pre-qualification of public construction projects in order to prevent accidents and facilitate the safety management of construction companies. However, the construction industry is still experiencing an increase in accident rates. Hence, there is a need to strengthen existing safety evaluation systems and requirements in public construction tendering. The objective of this study was to acquire and provide basic data for benchmarking to select tenderers in domestic public construction projects. In Singapore and Japan, safety evaluation systems and requirements are applied based on various aspects in order to screen tenderers. These evaluation systems include safety regulations and institutional requirements, as well as safety performance and safety management plans of respective construction projects. This study recommends that korean public construction projects also apply similar safety evaluation systems which include comprehensive safety criteria in order to decrease accident rates in the industry.

Delay schedule coming about duration extension is happening essentially because public construction project consist of many sub contractor. The method which can calculate delay day is suggested by many studies in case of happing delay schedule, but It is difficult to apply to real construction project because there is no mention about the control of The law of contract according to delay schedule. The law of Contract which is cost of account has more uncertain problem than FIDIC condition of contract. This study suggests method which can make extension of duration procedure clear in case of happing the reason of design change related with activity duration during carrying on construction, and a submission process of the reason of duration extension and modify schedule making way about section which is basis of calculating contract amount clear.

A construction post evaluation is introduced to provide information that can be used for similar construction projects in the future through the evaluation of the efficiency of a public construction project and the verification of the appropriateness of the project results. However, it is not widely used due to a lack of awareness of the method. For this reason, the aim of this study is to provide a basic frame that can be utilized as a reference for a similar project in the future based on the construction post evaluation. More specifically, a more effective analysis method for the construction post evaluation is proposed and then an exemplary analysis is performed based on the method. The paper analyzes 293 cases stored in construction CALS. Construction cost growth rates of railway projects are tend to be greater than other project types like highway, expressway, and harbour. Then, construction schedule grwoth rates of expressway are greater than others. This is expected to provide useful information for a future project, and serve as a basic frame. Moreover, it is also meaningful that a project can be analyzed from different perspectives through the construction post evaluation.

At the conceptual phase of a construction project, estimated construction cost is very important as it significantly influences the owner's decision-making. Accurate cost estimating, in the early stage of a public construction project, serves as a critical factor because initial decision-making effects the final cost of a construction project. However in the cases of Korean public apartment projects, excluding a few of the public owners, there is a problem in properly estimating construction cost due to the lack of construction cost estimating system. Thus, this research developed a public apartment cost estimating system using case-based reasoning that was suggested by a previous research with 66 cases of Korean public apartment projects. Based on the system experiments involving 19 public officers and 10 cases of Korean public apartment projects, the effectiveness of the system in terms of estimation accuracy and user-friendly was confirmed. As a result, the developed system has an error range of 1.47% to 13.74% and mean of 6.15%. In addition, the system was evaluated that it could greatly improve the current estimation task of public officers. Consequently, the results of this research can be used as a foundation for a technological advance in estimating construction cost and improving the accuracy and consistency of construction cost estimation.
