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.

Public construction projects are implemented by government or public agencies using public resources to enhance the welfare of the people. Therefore, this paper investigates the impact factors for public construction performance. Then, the weights for impact factors are assigned using AHP. The impact factors are categorized into construction policies, project management efforts, and project environment. Further, 16 detail impact factors are listed in each category. The results show that weights are ordered in appropriate budget, reasonable project implementation process, and pre-project planning. These impact factors are related with pre-construction management activities. However, construction related impact like procurement, work difficulty, and construction environment show relatively low weights. The results can be useful to improve construction performance with managing impact factors showed high weights.

In the construction project, construction supervisor influences greatly the construction managements such as process management, quality management, safety management, and cost management. Therefore, from the first stage of the project, the managing activities of the supervisor are consistently needed. But the assesment of supervisor's work and cost has not been made enough in the public construction project. And there have been doubts as to whether a supervisor can take a consistent managing activity from the early stage of the project. Accordingly, the works between Korean supervisor and foreign supervisor in their public corporations are analyzed and compared in this paper. And the evaluation is made each of the cost for supervisor and the cost for engineer as a substitute of supervisor in construction project. This study is believed to contribute to improving the supervisor's work and reducing the personnel expenses and construction indirect cost.

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.

The Construction Management(CM) System in Korea is systematized both in name and reality by being prescribed in Construction Industry Act('97) and Construction Management Act('01) through various discussions considering reformation of construction industry structure and enhancement of construction technology competitiveness. Specially in the public construction works, CM Pilot Project is promoted by central government for the activation of CM system introduced for efficiency of public construction project. The promotion of Pilot Project is not only the settlement and activation of CM system but also the process to embody and diversify the CM system. Now we should develop various CM application type such as Owner type, PM type and type for private capital project in doing so. And with this efforts, we could expect that CM system should play an important role to enhance the efficiency of public construction works and should affect private construction sector.

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.
