건설산업에서 정부는 발주자이며 최대 수요자 이고, 건설산업의 보호 ${\cdot}$ 육성 및 발전을 선도하는 견인차이다. 특히 발주와 낙찰제도는 발주자인 정부와 수급자인 건설업체 간의 계약관계만을 규정하는 것이 아니라 건설산업 전반에 걸쳐 큰 영향력을 가지게 되므로, 발주 및 낙찰제도는 건설산업 발전을 위한 정부의 의지표현이라 할 수 있다. 따라서 정부는 비효율적 요소의 개선, 비용효과 및 투자효율성 향상을 위하여 노력해야 할 것이다. 본 연구에서는 선진국과 국내의 발주 및 낙찰제도를 혁신의 주체, 의지, 핵심방향, 발주자의 의식변화 측면에서 분석, 시사점을 도출하여, 국내 발주 및 낙찰제도 개선방안을 정부와 민간 공동협의체 구성, 일관되고 지속적인 개선 추진, 개선의 목표는 효과/효율 향상, 발주자의 의식변화 및 역량강화 추진의 측면에서 제안하였다.

Humanity is facing a number of serious issues associated with increased energy consumption and environmental pollution. Various studies/guidelines concerning sustainable building construction have suggested solutions to these disastrous problems, including: net-zero energy buildings, the green building certification system, and others. Sustainability pursues three expected effects: environmental, social, and economic merits. Korean Green Building Council (K-GBC) has also announced the Korean Green Building Certification System (K-GBCS) since 2003 based on sustainability. Some positive social and environmental aspects of the K-GBCS have already been reported. However, it is somewhat difficult to verify its economic merits, which are crucial to ensuring the validity of the K-GBCS. This research aims to verify the economic merits of the eco-friendly Korean-style condominiums accredited by K-GBCS. Following this, the expected economic effectiveness of K-GBCS will be examined in terms of sustainability. The underlying assumption is that the potential economic effect should reflect the actual economic merits, and should reflect the value of the housing in particular. According to the analysis of the variance, it can be concluded the value of green certified buildings is statistically higher than the value of non-certified buildings. Furthermore, it was also observed that this tendency was more dominant in Gyeonggi Province than in the City of Seoul. This may be caused by one of the variables: the proximity to downtown. In future studies, this variable should be studied in greater detail.

This paper presents a parametric study of reinforced concrete bridge tall piers with hollow, rectangular sections. Such piers are typically used in railway construction of prestressed concrete viaducts. Twenty one different piers have been studied with seven column heights of 40, 50, 60, 70, 80, 90 and 100 m and three types of 10-span continuous viaducts, whose main span lengths are 40, 50 and 60 m. The piers studied are intermediate columns placed in the middle of the viaducts. The total number of optimization design variables varies from 139 for piers with column height of 40 m to 307 for piers with column height of 100 m. Further, the results presented are of much value for the preliminary design of the piers of prestressed concrete viaducts of high speed railway lines.

The corrugated steel plate structures is applied to the construction of mountain tunnel portal part with shallow depth, the tunnel on the outskirts of urban areas and ecology move passage. In this study, A finite element method is used for research the behavior of corrugated steel plate structures due to construction position under declinating earth pressure and excavation depth. A finite element method were performed varying construction position(10, 15, 20 and 25m) from slope and excavation depth from surface. The hoop thrust and moment, displacement of corrugated steel plate subjected to construction position and excavation depth is determined from a finite element method. From results of finite element method, it was found that the increase of thrust and the decrease of displacement as the amount of distance increase from slope with construction position. But the thrust and moment, displacement has not different value with excavation depth.

The widespread of IT technology caused a remarkable change in many industries and the construction industry is also one of them being influenced in the form of CIC(Computer Integrated Construction) and BIM(Building Information Modeling). Construction projects have many participants from various disciplines involved throughout the entire process. Therefore the success of the project greatly depend on the efficiency of decision-making using the information generated from each process stage. Looking from this aspect, the greatest potential value lies in the planning and pre-design stage when considering the construction life cycle. In this paper, we propose a project on developing a 3D object oriented simulation system for supporting the pre design phase. We define the needs for such system through previous case studies and suggest a to be process model. Finally we anticipate the effects that the project will eventually contribute to the construction industry.

Major construction projects will be directly related to construction costs and disclosure period depending on the selection of the construction method. However, there are some sites that choose without taking into account sufficient conditions. Therefore, the company wants to present a quality model that suits the characteristics of major engineering fields.

This research documents the initial findings and recommendations for developing a risk management tool to assess and quantify the risks associated with the construction of the next generation of nuclear power plants. The proposed tool builds upon the Construction Industry Institute's International Project Risk Assessment (IPRA) Best Practice. This paper provides an overview of the investigation to assess the unique risk elements pertaining to nuclear power plant construction and documents the preliminary findings from historical project performance data to better understand the function and use of the IPRA's Relative Impact value.

The technical proposal bidding system emphasizes the evaluation of the construction company's technical capabilities, with the aim of improving the quality and cost-effectiveness of the construction. However, in the VE analysis and proposal process for technical proposal bidding, the ideas are often reused from similar past construction projects, and the application of new construction technologies/methods is often lacking. Therefore, this study proposes a methodology for managing VE proposal information by integrating it into a BIM model using parametric modeling. This research developed database based on the existing VE proposals and new construction technology/method information from the Korea Institute of Civil Engineering and Building Technology. And by using parametric modeling, the proposed method integrate the VE database with BIM model. The methodology proposed in this study is expected to improve the reliability and effectiveness of VE-related idea proposals in technical proposal bidding.

건설사업의 목표는 해당 사업의 특성에 따라 우선순위의 차이는 있지만 기본적으로 원가절감, 공기단축, 품질확보로 압축될 수 있다. 그 중 원가절감은 발주자와 건설산업계 모두에게 중요한 목표이며 이를 달성하기 위한 전략과 방법은 중요한 관심사라 하겠다. 원가절감은 사업범위, 품질, 안전, 상호 비즈니스 관계, 고객만족 등 타 매니지먼트 요소의 희생을 수반함으로써 부정적인 이미지로 인식되어 왔다. 그러나 원가절감이란 용어는 부정적인 이미지를 극복하고 가치창조(value for money)를 달성시키는 긍정적인 방향으로 변화하여야 할 것이다. 본 연구에서는 영국 Constructing Excellence의 성공사례를 중심으로 원가절감의 성공사례 분석을 동하여 긍정적인 원가절감 전략의 특징을 도출하고자한다.
