This research is a preliminary one to investigate transitional problems of actual-cost-date-based contract cost estimation method and suggestions for counteracting them. As parts of it, in this paper, the brief background and methods of the new method and contract costs estimated by introducing it are presented. The results of five projects' contract costs are compared to those estimated by the conventional quantity-based method. Comparison of the both is conducted in terms of total contract costs and contract costs according to type of sub-contracts. Finally, the propositional differences of the later to the former are analysed.

Nowadays, domestic construction companies make an effort to share knowledge and experience accumulated while conducting a project. One way of improving knowledge sharing is to develop specifications which are linked to the expert's knowledge and experience based on the specification classification. Therefore, the purpose of this paper is to review the current domestic specification system and develop the specification linked to the construction lessons learned database. It is expected that the proposed specification system will support the decision making process by effectively providing the knowledge and solution.

This study introduces the current status of the design for safety(DfS) introduced as one of the owner - centered construction site safety management plan, and presents the problems and the improvement plan. The design for safety has been shifting from the construction management-oriented safety management to the owner-centered safety management system, The owner has to make the design considering the safety from the design stage centered on the owner. The owner has to review and approve the adequacy of the safety-conscious design and The risk factors that can not be eliminated during design are the system to prevent the disaster at the construction site by planning to eliminate the risk factor when writing the safety management plan that is made at the construction stage. The design for safety system implemented from May 2016 will be further developed to prevent the risk of safety accidents that may occur in construction sites, contributing greatly to the reduction of construction accident. In addition, it suggests ways to develop more efficient and convenient system through continuous hazard finding and system improvement.

최근 몇 년간 지속된 국내 건설경기 침체로 설비건설업계는 많은 어려움을 겪고 있다. 또한 금년 1월 1일부터 기계설비공사의 겸업제한이 폐지되면서 일반건설사도 기계설비의 면허취득이 가능해지는 등 설비건설업계에 많은 변화가 일고 있다. 이처럼 개방과 불황의 파고를 넘기 위해서는 기업의 경쟁력 강화가 그 어느 때보다도 절실히 요구되고 있다. 기업은 신기술 신공법 개발 및 알뜰경영으로 경쟁력을 강화시키는 것도 중요하지만 전사적인 안전관리로 근로손실에 의한 생산성 저하, 재해보상금 지급 등 안전사고와 관련한 지출을 크게 줄이는 것도 경쟁력 강화의 한 요인으로 주목되고 있다. 최근들어 안전 보건 및 환경 등에 대한 관심이 높아지면서 건설업계는 기업경영의 우수성을 객관적으로 평가받을 수 있는 안전보건경영시스템 인증 취득이 늘어나고 있다. 더구나 설비건설업계의 숙원사업인 분리발주와 유사한 주계약자공동도급이 올해부터 기계설비공사에 적용되면서 일반건설업체도 기계설비건설업체와 공동도급을 받기 위해 노력하고 있다. 이럴 때 설비건설업체가 경쟁에서 우위를 선점할 수 있는 요건은 무엇일까? 기술력, 신뢰도 등 여러 가지 요인이 있겠지만 안전보건경영시스템 인증도 한 몫 할 수 있을 것으로 예상된다. 지난 2001년 안전보건경영시스템 인증이 도입된 이후 지난 3월 30일 현재 설비건설업계는 14개 업체가 인증을 취득했다. 본지는 지난 2006년 9월호에 건설업 안전보건경영시스템을 특집으로 소개한 바 있다. 최근들어 안전보건경영시스템에 대한 관심이 높아지면서 이에 대한 문의가 많아짐에 따라 이번 호에는 안전보건경영시스템에 대해 다시 한번 알아본다.

The public construction industry in Korea involves a variety of stakeholders, encompassing multiple layers of contractual relationships that crisscross between the State as project client and the contractors, as well as subcontractors. In such a hierarchical landscape, managerial crises of contractors involving bankruptcy or insolvency can result in unexpected damages for both clients and subcontractors. Accordingly, the applicable legal framework requires project clients to act as patrons in relation to making payments to subcontractors, and stipulates provisions pertaining to direct payments to subcontractors in order to promote the balanced development of the national economy in terms of the public interest by protecting small and medium-sized businesses working as subcontractors for large businesses. However, the relevant legal documents provide for different payment criteria and procedures from document to document, and leave room for variations in the interpretation and construction of applicable provisions, which leads to disputes and discrepancies in court rulings. For this reason, it is necessary not only to compare and analyze statutory provisions pertaining to direct payment to subcontractors, but also to review issues of contention in actual cases. This study aims to analyze issues in cases involving payment to subcontractors from the perspective of the project client overseeing and supervising the construction business. The conclusions from such an analysis will help to effectively resolve subsequent cases of a similar nature by suggesting a strategy to improve the relevant statutory provisions pertaining to direct payment to subcontractors.

Public institutions recognize the importance of cost management from the planning stage but they do not have an organized construction cost estimation and management system. Thus, at the stage of planning a new public construction project and estimating the cost, those in charge of budgeting estimate construction cost based on existing data and experiences, compare construction cost estimated after the basic design stage and the execution design stage with budgets, and then decide whether to continue the project or change the design according to the budgets. Therefore, we would develop the cost prediction model through regression analysis that can predict construction cost in Schematic Design Phase of the Public Multi-Family housing. Accordingly, if public institutions have a construction cost prediction model and management system that can estimate the optimum construction cost, they can make and execute budgets in a more efficient way than they do at present.

Since CM for Fee has been introduced in domestic market of construction industry, Construction Management(CM) has been familiar with one of the established delivery systems in Korea. However, CM(CM for Fee) construction market has been stagnant consistently due to recent economic recessions. The fundamental causes of the current depression of CM construction market are highly related to the social/environmental factors(such as owner's negative perception about CM services, exclusive formation of the CM markets, unfeasible fee and limitations on technology developments in CM services) and the shortage of institutions associated with CM. Accordingly, fundamental improvements on the CM environment are required. This study suggests the feasible methods for improvement on CM system based on fundamental analysis of problems related to the environmental factors by conducting a delphi technique with professional personnels on various positions in CM markets.

Estimated construction cost is an important index to secure an optimal budget which needs to go into construction projects in the previous of basic design phase. In order for public institutions to calculate the estimated construction cost, the cost per unit area of public buildings is used. However, the current calculation method of the estimated construction cost in public buildings is impossible to reflect the characteristics of many facilities and combinations. The purpose of this study is to develop an estimation model in the previous of basic design phase for the elementary, middle and high school facilities. it is expected that it is possible to estimate the construction cost of the elementary, middle and high schools in a reasonable and reliable manner through the estimation model developed in this study.

In the evaluation for ordering BIM-based projects (Design Build) of Korean National Railway, criteria of BIM-based smart construction technology are assessed. Unlike the existing assessment criteria, performance resources and detailed assessment guidelines have been added by this research. The purpose of this study is to propose qualification assessment standards according to specific guidelines when evaluating on the phase of bidding for BIM-based projects. In the study, an improved evaluation standard (draft) was arranged based on two consultation meetings and surveys of related companies, applied to existing projects with the companies that won the bid, and validated. As more specific and added criteria compared to the existing standards, it could reduce the difficulty of evaluation for BIM capability and lay the foundation for railway BIM-based project management.
