When managers estimate exact construction cost at early stage and design phase, they can reduce construction cost in a more efficient way than to predict at construction stage. But, the current of public construction cost estimation and management is concentrated almost after detailed design phase. Therefore, construction cost management in design development phase to generally use approximate estimating is not correct. Also, the existing construction cost used the method that estimated by gross floor area-based cost estimates at design development phase. So, it is difficult to show the specific amount of materials and basis about the estimated cost of the construction. This study derived problems and limits of construction management at design development phase in case of public office building project through review of literature and current survey, and suggested estimating process model process of structural construction cost go improve these matters.

공공건설사업은 사람들의 복지 후생 향상과 국가 또는 공공단체 등이 공공자원을 사용하여 시행된다. 따라서 본 논문은 공공건설사업의 성과를 제고시키기 위해 건설성과에 영향을 주는 요인을 파악하였다. 그리고 전문가를 대상으로 AHP를 실시하여 영향요인 별 영향정도를 가중치로 제시하였다. 이를 위해 먼저 영향요인을 건설관련 제도, 프로젝트 관리노력, 프로젝트 환경을 구분하고 세부 영향요인 16개를 제시하였다. 그 결과 적정 예산확보, 합리적 사업시행 절차, 사전 기획 등의 순으로 가중치가 결정되었다. 이는 시공 이전단계의 업무에 해당되는 요인들로 시공이전단계의 관리업무의 중요성을 나타내고 있다. 반면, 자재조달, 작업난이도, 현장 조건 등 시공과 관련된 요인의 중요도는 상대적으로 낮은 것으로 나타났다. 본 연구 결과를 바탕으로 가중치가 높게 나타난 영향요인을 중점 관리하여 건설공사의 성공적인 수행이 가능할 것이다.

건설프로젝트에 있어서 공사감독은 공정관리, 품질관리 안전관리, 원가관리에 중요한 영향을 미친다. 그러므로 건설공사의 초기단계에서부터 감독의 지속적인 관리활동이 필요하다. 그러나 국내 공공 건설공사에서 감독의 업무량과 비용에 대한 평가가 미비한 실정이다. 또한 공사 감독이 초기단계에서부터 지속적인 관리활동이 가능한지에 대해서도 회의적인 시각이 상존하고 있다. 본 연구에서는 우리나라 공공발주처에서 시행하는 공사의 감독 업무와 외국에서의 공사감독의 관리활동을 비교$\cdot$분석하였다. 또한 국내 건설공사에서 감독에 소요되는 비용과 감독을 대체한 감리원을 활용하였을 때의 비용을 평가하였다. 이를 통하여 향후 감독업무의 개선이 가능하고 비용적 측면에서 인건비 등 공사 간접비의 절감을 기할 수 있겠다.

Procurement system of public construction projects in Japan is changing with diversity in rapid pace. The quality assurance and risk management of construction projects should be more certain as the projects are turning into larger scale and more complexed. The clients in the public sector will want to make the relation of responsibility among the client, the designer (architects and engineers), and contractor clearer in terms of role and risk. Public-Private Partnership (PPP) is one of the methods for collaboration of the public sector and the private sector in public construction projects where the public utilizes the ability and suggestion of the private. Private Finance Initiative (PFI), Design-Build-Operate (DBO), market testing, designated manager system, outsourcing of tasks in local governments are well-known as examples of PPP in Japan. Indeed, there is an obvious trend that Design-Build (DB) is adopted in public construction projects in many countries including Japan. In this paper, the public construction projects in various procurement systems are surveyed and analyzed. They are not limited within the traditional procurement, Design-bid-Build, a separate order system of design and construction. Design-Build or PFI are adopted. In particular, contract by wide range including maintenance of equipment can be found. On the other hand, modification from originally typical PFI is taking place, such as concept design and project finance are removed from the roles and the tasks of the special purpose company (SPC) in PFI. Standard roles and tasks in a construction project are modeled in this paper.

As the business environment for construction enterprises has been worse, the level of their dependence on public projects increases. Under these circumstances, the public owners should pursue more efficient management process and make continuous efforts to establish strategic project-oriented organizations. There are growing concerns on owners' role with the recognition that the public owners are the key stakeholders to improve effectiveness in public sectors and reinforce competitiveness of entire industry. This study reviewed the characteristics of public construction projects with the concept of program, evaluated the current status of program management capabilities, and discussed the requirement for effective program management.

우리나라에서 건설산업의 구조개편, 건설기술의 경쟁력 향상 등과 맞물려 CM에 대한 다양한 논의과정이 있었으며 건설산업기본법('97) 및 건설기술관리법('01)에 CM제도가 규정됨으로써 명실상부하게 체계를 갖추게 되었다. 이 중 특히 공공사업에 대해서는 효율성 제고라는 문제의식에서 출발하여 제도의 활성화를 위한 시범사업(Pilot Project)이 정부를 중심으로 추진중에 있다. 현재 추진중인 시범사업은 제도의 정착, 활성화 뿐만아니라 기존의 CM제도를 좀더 구체화하고 다양화하는 과정으로서 그 시행의 중요성을 인식할 수 있을 것이다. 이러한 시범사업의 추진을 통하여 현재의 감리중심의 CM제도에서 발주자 및 사업특성을 고려할 수 있도록 Owner형 CM, PM형, 민자사업 적용방안 등 다양한 CM적용형태를 모색해야 할 것이다. 이러한 노력들은 공공사업의 효율성 제고 뿐만아니라 민간부분에도 많은 영향을 미칠 것으로 기대된다.

As a project delivery method, Design-Build (DB) has provided owner, architect, and contractor groups with a process of early design and rapid construction for the past three decades. Although there are many benefits to using standard DB, dissatisfaction has arisen due to limitations to innovate, limited owner involvement during design, and often lengthy procurement. Progressive Design-Build (PDB) has become an appealing alternative providing benefits not seen with standard DB. This paper investigates how PDB impacts a project and how it compares against standard DB; it also presents a proposed framework for evaluating the owner's responsibility and assessment of a project, which we named the "Four Pillars of Project Success". The four pillars are defined with respect to an owner's responsibility and assessment of a project, including project predictability, project risk, project schedule, and project cost. We conducted a literature review, examined several public project case studies, analyzed PDB project information collected by the Design-Build Institute of America (DBIA), and held stakeholder interviews with owners, contractors, and architects who have used both PDB and standard DB. This paper offers insight into PDB's structure and outcomes so an owner group can make an informed decision when considering PDB as their next construction contracting method.

Recently, public office building projects are being recognized by many construction engineers and researchers, as the critical projects in the construction industry. The project budgets have sometimes exceeded due to the lack of core knowledge, experiences, skills and experts concerned in cost planning and estimating in the pre-construction stage. It has been highlighted that planning and estimating effectively the cost of public office building projects as critical in the design stage. Within this context, some cost data books and systems, such as RSMeans cost data systems and Spon's price book, have been systematically developed and used by many construction cost managers and organizations in order to effectively estimate and use their project budgets. As a result of this research, a cost estimating model for finishes has been developed, considering the cost data used in public office building projects.

Today, government is no longer considered the sole provider of public works or services. Public-Private Partnership (PPP) has been recognized as an important approach to solving problems for governments in providing public works and services. However, the joint ownership of public works/services complicates the administration of PPP projects. Particularly, the fact that government may rescue a distressed project and renegotiate with the developer causes serious problems in project procurement and management. This paper aims to study when and how government will rescue a distressed project and what impacts government's rescue behavior has on project procurement and contract management. A game-theory based model for government rescue will be developed. This pilot study, the author hopes, may provide theoretic foundations to practitioners/policy makers for prescribing creative PPP procurement and management policies and for examining the effectiveness of PPP policies.

In recent years, the bid-rigging in public construction markets has been treated as a critical issue in Fair Trade Commission. The investigation revealed that the collusion was implemented extensively in every area from the material supply to the construction service of general contractors. This study reviewed the causes of the bid-rigging in public construction projects, and proposed the improvement plan to eradicate bad practices. Firstly, the causes and purposes of bid-rigging were categorized into two types of internal factors from construction companies and external environment factors influencing business activities. Secondly, the system development method was explained to detect the signs of bid-rigging based on the technical proposal documents in open tender. The detection systems of repetitive public owner also provide the function of sharing data on the companies and cases to violate the fair trade regulation. In addition, the problems and improvement direction of public procurement policies were discussed.
