  • 최근 국내 건설산업은 건설업체의 경영난과 물량 감소로 인해 위축되고 있다. 국내 건설사들은 건설시장에서의 경쟁 우위 확보를 위해 모든 공종에 대해 원가절감 및 품질향상을 위한 노력을 기울이고 있다. 가치공학(VE) 기법은 건축공사에서 원가절감뿐만 아니라 공기 단축과 품질향상을 위한 도구로 활용되는데, 골조 공사 분야에 적용되는 성과가 상대적으로 미미한 실정이다. 공장 건설에서 골조 공사는 전체 공정에 큰 영향을 미치는 주요 공정이므로 골조 공사 계획단계에서 VE 기법을 도입해 설계도서와 현장 여건을 분석하여 품질과 안전을 확보하면서 공사 기간 단축, 원가절감, 작업성을 높일 수 있는 대안을 개발할 필요가 있다. 본 연구는 공기 단축, 원가절감, 시공 안전성 확보를 위한 기초연구가 될 것으로 기대된다.

  • Environmental issues become one of today's central concerns due to draining natural resources and environmental pollution. Architecture is given a great deal of weight on the evoking environmental pollution. In this point of view, polluting factors in architectural planning and construction were predicted in advance and alternative plans were studied, In investigation of alternative plans, both environmental pollution and economical efficiency of various alternatives were considered. A office building was analyzed for energy consumption and construction environmental load by appling LCA. Applying LCA to a office building includes a total amount of materials and energy consumption, environmental impacts and economical efficiency evaluation. In present study, LCA applied to electrical part of a office building and economical efficiency evaluation was considered.

  • Numerous reports show that alternative project delivery systems (PDSs) such as design-build (DB), construction management at risk (CMR), and design-build-maintain (DBM) are increasingly used in many countries. This study compared characteristics of each PDS (design-bid-build (DBB), DB, CMR, or DBM) by analyzing quantitative data from 9 research articles. In order to compare characteristics between DBB and alternative PDSs, the study is based on principal 3 factors - Time, Cost, and Quality. DB shows the best performance in the time part and also the cost performance depending on facility type and project size. The performance of quality has minor difference among different PDSs. These results support the fact that using an appropriate PDS by the characteristic of a project makes high value of efficiency and productivity.

  • 건설시설물의 기능향상과 경제성을 제고하기 위하여 도입된 설계VE제도는 2005년 12월부터 100억 이상 건설공사에 확대 적용되고 있다. 그러나 VE가 형식적이고 결과 중심적으로 실시되고 있어 VE를 통한 가치창출의 극대화라는 VE본연의 목적을 달성하지 못하고 있는 실정이다. 본 연구에서는 그동안 국내에서 실시된 턴키 및 대안입찰사업의 설계VE 사례를 통하여 설계VE의 성과를 분석하고 개선방안을 제시하고자 한다.

  • VE is one of the technologies that are essential to promote cost reduction and performance improvement in construction projects. In the VE process, there are very important steps in deciding whether to adopt VE ideas and alternatives or not. However, when examining the possibility of selecting and adopting alternatives, it is difficult to clarify the differences and characteristics of the existing and improved proposals due to lack of understanding of the owner and inadequate consideration of harmonization with the alternative surroundings. In order to overcome these problems, it is necessary to effectively exchange information related to alternatives among VE participants and to examine the applicability of VE alternatives more in-depth. Therefore, in this study, a process for reviewing the applicability of VE Alternatives using BIM based VR was proposed to review more appropriate VE alternatives.

  • The building production system has been analysed by the dichotomy "employer-contractor" relationship, which failed to take into account of the role and function of multiple stakeholders within the life-cycle supply chain. This is further observed in the current conflict resolution model, which, in my argument, struggles to contribute to industrialize the building production and achieve better efficiency and effectiveness as expected. The purpose of this paper is to critically assess the issues of current programme-based conflict resolution model, and discuss alternative models how they can be modelled and applied to the construction projects. The conclusions of findings are; First, the current model is framed around the contracts and dispute resolutions based on the legal concept of "claimant and respondent" where one party(s) advances a claim once and the other(s) objects, as such it fails to reflect the nature of construction projects where multiple stakeholders are involved concurrently and for a long period of life-cycle of buildings. Second, an alternative is "Six-stakeholders model" which represents the multiple stakeholders and clarifies the flow of obligation-liability-monetary relationships among participants for a long period of life-cycle of buildings. Further, with reference to both historical and recent cases, a reflection and insight into pros and cons of programming method is added, especially as to why this method is considered to have become a mandate of the modern construction management, and how academics and practitioners should deal with it more cautiously and prudently.

  • In this paper, a new type of precast perforated concrete block is presented to be used in the construction of a step seawall. The overtopping rate of the perforated step seawall is lower than that of the traditional non-perforated step seawall. In construction stage, the cost of total construction of the perforated block is cheaper than that of traditional block. The new type of perforated block may be used as an alternative for shore protection facility.
