  • 최근들어 우루과이 협상의 진전이 가사화됨에 따라 서비스업의 개방이 현실적인 사항으로 인식되고 있고, 서비스업으로 분류되는 건설업도 개방압력에 직면해 있다. 건설시장의 개방에 따라 가장 크게 우려되는 부분은 국내업체의 설계 및 엔지니어링 분야를 들 수 있으며 선진외국 건설업체와 비교했을 때 매우취약한 실정이다. 이에 대처하기 위해 설계 및 엔지니어링 기술을 육성시킬 수 있는 기술경쟁입찰 풍토를 조성할 필요성이 있으며 설계 및 시공단계의 상호조정을 통하여 공사수행을 보다 효율적으로 수행할 수 있는 일괄입찰제도의 확대운용은 필수적이라 하겠다. 따라서 본 연구는 국내 일괄입찰공사의 확대시행을 위한 현행 일괄입찰제도의 개선방향을 설정하고 일괄입찰제도 절차의 개선안을 제안하여 설계입찰자의 평가 및 낙찰자 선정에 대한 구체적인 개선안을 도출하고자 하였다. 이와 같은 개선방안의 마련을 위해 설문 및 면담조사가 실시되었으며 최종적으로 실무자들과의 총의회를 통하여 최종안을 제안하였다. 본 연구의 주된 내용은 일괄입찰공사유형의 제시, 사전자격심사, 입찰서류 및 입찰기간, 입찰자평가시 발주처참여, 낙찰자선정, 실시설계판정, 건축$\cdot$토목$\cdot$기계$\cdot$설비에 대한 새로운 평가체계 제시 등으로 요약할 수 있다.

  • Although design-build construction projects have recently increased. general conditions of construction contract are not reflecting the characteristic of design-build construction projects neither performing its fundamental roles as implying many claim elements. So. this study aims to propose the basis for improving the general conditions of the domestic design-build construction projects. This study reviews literatures associated with design-build construction contract and analyses domestic general conditions into foreign standard forms of general conditions. Additionally, it is examined the problems of design-build construction contracts and performed questionnaire survey to the practitioner in the construction contract field. In doing so, this study suggests the direction for improving general conditions of domestic design-build construction projects.

  • Domestic Design-Build, which has applied for client's convenience, has many problems Because It is being applied in the building law, which devides between architects and contractors. Among problem the relation between architects and contractors is a typical problem. It makes a quality decline and a design skill decline. In result, it causes insufficience of competitive power in overseas projects from now on. So we present the plans to improve mutual relations between architects and contractors. And we induce development of design skill and good quality of building by presenting a coordinative committee model between them in Design-Build projects.

  • Owners, local autonumous entities, have a burden on operating project for the lack of their management capacity such as specialty and human resources. In this reason, they want to perform project with CM methods. But there have been only a few case of CM operation and application in a huge construction project. The complex formations of CM and responsible management are used in those project. This situation originates in the lack of CM specialist. Because the CM service used in those case is generally performed as the mixture of responsible management service and design management service, it is not the prototype of CM. The purposes of this study are to present the solutions to the problems concerned with the design development phase management, design phase VE, the application of Fast-Track, PMIS operation and CM execution, etc, and establish the plan to perform CM services efficiently in the public sector through analyzing the case of CM application in Gwangjin-Gu Culture & Sports Center.

  • Recently, Design-build project as delivery system public construction sector tends to be increased according to the Masterplan for promotion of construction technologies, and construction projects are increasing their complexity, variety and scale. And owner's requirements become various. Preliminary design for design eligibility judging of design-build has been designed excessively to get a good point and this tendency includes the elements which is capable of wasting the budget. Because of excessive design, owners require to apply VE study into the design development phase but in the Design-build system, VE application has not been of no effect that owners expect, owing to the characters of lum-sum contracts. The purpose of this study is to propose the plan for effective application of VE in the design development phase in order to solve the problems such as excessive design of preliminary design in the design-build project. This study established plans for VE application through investigating and analyzing VE application case and then proposed the applications in the aspect of regulations and contracts, parties participated in project, VE operation through research for verification of usefulness.

  • In order to build up competitive power in construction market and to cope with international policy, Design-Build bidding is one of the viable bidding system, encouraging collaboration between design office and building construction firm. Design-Build is a promising delivery system to help expediting schedules, saving costs, and improving Quality. However, the problems of Design-Build project in the domestic construction industry are not to be able to take advantages of fast-tracking and value engineering process, because of the problems of inappropriate system and participants' inexperience. The purpose of this study is to suggest alternatives for Design-Build bidding of public sector in the domestic construction industry in the costs, quality and time aspect.

  • Although the order of Design-Build is being expanded by increasing construction scale and demanding hybrid function, the suitable regulation of the contracts is not settled. Design-Build is way by government because there are big construction of much government leading in contract relation high position occupy. So, case that prebendary's claim institution develops by litigation is very rare. But, recently Design-Build is magnified. So, these dispute factors is becoming visualization gradually. The contract system is needed to be consistent by international standard to deal with the problem. This study suggests the useful solutions in detail concerned with the main factor of change order claim by each Design-Build phases through practical sorting and analysis of the causes of Change Order-Claim.

  • Turnkey contract system is an effective ordering system for the organizations that technical engineers are insufficient in their construction projects. It is possible to reduce project duration and to improve project Quality in an integrated contract system between design and construction. However, owners can have a difficulty caused from unitary responsibility system. This study analyzes present situation and problems of turnkey contract system in our country. The results includes various methods for improving the system based on the analysis of bid price nd selection procedure.

  • Recently, a delivery system has been rapidly changed in the global construction market. Also, construction projects are becoming bigger and more technology-intensive. A lot of projects have been delivered by Design-Build(DB) System; from the standpoint of cost, approximately 40% of delivered constructions by a Public Procurement Service were DB in 2009. Nevertheless, the achievement has not surpassed our expectations on management of the project cost. On the characteristic of DB, the reasons why that happens are that projects contract have been signed after the Design Development Stage; the insufficient review about new technology and up-to-date construction methods; a lack of discussion in process of design. Those reasons cause a risk of increasing Cost of the projects. In order to solve these problems, it is desirable to find Cost-increasing factors in promoting the projects and select on the order of priority for Risk-Factor with careful management. Therefore, this study analyzed the weight of each phase of the project on the authority of properties of DB project, and identified Risk-factors which is increasing the cost on the aspect of project management. Based on this analysis, the impact assessment of Risk-factor is evaluated through the Failure Mode and Effect Analysis(FMEA).
