  • This study purpose is seeing that the independent standard sufficiently reflecting the characteristics of the school facility as the basic material needed to calculate the maintenance and repair expenses is needed to make a more realistic and valid qualitative VFM analysis of the school BTL project. this study attempted to develop the standard for the repair cycle and rate and economic year of the school facility. The quantitative VFM analysis should be conducted based on the repair cycle and repair rate proper to the school facility, not the residential space, when calculating the maintenance and repair expenses of the operating expenses of the school facility. An attempt was made to calculate the repair cycle, repair rate and economic life of 114 component materials of the school facility judged to be able to explain the school field best. And it was confirmed that the repair and maintenance expenses more is needed to be set by about 35% than the existing maintenance and repair expenses.

  • 건설산업에서 안전관리가 오랫동안 중요한 화제중의 하나로 대두되고 있으며 수많은 노력에도 불구하고 여전히 타 산업에 비해 높은 재해율을 보이고 있다. 이와 관련되어 많은 연구들이 진행되었으며, 대부분 시공자 또는 시공단계를 중심으로 진행되었다. 그러나 사업초기단계가 건설안전에 미치는 영향이 가장 높고 발주자 등 사업초기단계의 의사결정자들이 중요한 작용을 함에도 불구하고, 아직까지 건설사업 생애주기를 포괄하는 안전관리체계가 미흡한 실정이다. 게다가 건설사업에서 방대한 정보가 생성되지만, 이러한 정보들은 각 생애주기를 거듭할수록 정보들의 가치가 증가하는 반면에 비효율적인 측면을 보이고 있다. 이는 참여자들 간의 부족한 정보 공유 및 전달과 미흡한 표준으로 인한 것으로 판단되며, 이는 또한 정보가치들의 손실을 야기한다. 따라서 본 연구에서는 건설산업 측면에서 안전관리 정보이양의 효율성을 분석하는 것을 목적으로 하며, 이를 위해 우선적으로 건설안전 정보를 체계적이고 효율적으로 관리 및 활용하기 위한 안전관리 Framework을 '안전관리 업무기능', '건설사업 생애주기', '산업위계'를 포괄하여 제안하고, '안전관리 업무기능'을 계층적 구조로 5개의 대분류, 13개의 중분류, 32개의 소분류로 세분화함으로써 Framework을 구체화하였다. 다음으로, 안전정보이양의 효율성을 분석하기 위해 '업무기능의 중요도'와 '정보이양의 효율성'을 평가지표로 설정하고 전문가 인터뷰를 통해 평가를 실시하였다. 본 연구결과는 건설산업에서 안전관리를 보다 체계적이고 효율적으로 구현하는 기반을 마련하고 나아가 안전관리 역량을 강화하기 위한 기초자료로의 활용을 기대한다.

  • In this paper, an integrated management software is developed to promote the business competitive power. The interoperability among the software accounts for an ever growing performance of petrochemical plant project. If the interoperability is built up, company has taken advantages of quality, schedule, cost, and safety by active communication. The advantage of an integrated management software is examined in three aspects. In efficiency aspect, It takes advantage of the saving about the various information and the standard of project performance procedure. In quality, the integration gave aid to a quality improvement through team collaboration and data management within project life cycle. In cost, poor communications between systems waste 30% of project costs. If information could be inputted once and used by all, reductions in delivery time up to 40% were possible. Therefore, 10% savings of engineering cost was also possible.

  • The Construction Industry Institute (CII) developed the Project Definition Rating Index (PDRI), as a part of their Front End Planning best practices, which helps project managers assess and measure project scope definition risk elements. U.S. Green Building Council are seeing the benefits of sustainable building and Leadership in Energy and Environmental Design certification by positively impacting life cycle costs, building marketability, and organizational productivity. However, there have been no efforts to integrate these two planning tools in construction industry. By applying a supplemental tool which combines the PDRI with the LEED rating system, construction industry can develop and implement a tailored instrument that leads to total project success in sustainability. The objective of this research is to assemble a new front end planning mechanism for green buildings by incorporating the current PDRI and LEED systems.

  • As a recent global trend, the majority of plant projects are delivered through EPC or EPC-turnkey contracts, where a contractor's liability is more complicated because of the mega size scale and financing method. Previous researches have been lacking a practical usability for project members for liabilities of contracts. Those were focused on solving the claims or schedule calculation issues only. The objective of the present study was to develop a validation process for LDs (liquidated damages) in contractor's liabilities with various case studies and expert judgments. As summarized in this paper, the processes and tools were developed with project life cycle process. The project preparation phase includes 3 step check lists to determine the Go or No-go for projects. In progress phase, contractors should focus on the response strategies for claims with liabilities. The study concludes that those developed processes and tools will help to manage risk of LDs for the contractors in the overseas projects.

  • Health and safety in the construction industry continue to fall behind many industries despite much effort to improve the status. A considerable amount of research has been conducted to try and contribute to addressing the problem of health and safety (H&S) in the construction industry. A number of studies have looked at the role of various construction project stakeholders and their contribution to H&S. However there is no clear identification of the extent to which various stakeholders could contribute and therefore influence the outcome of H&S on construction projects. In view of the above, the current Delphi study went a little bit further and sought to establish the impact significance of construction clients and designers on H&S. This paper will present findings from the study which is the impact significance of clients and designers on H&S consideration throughout the project life cycle.

  • Since the 1990's the fleet of the Dutch Railways showed a dramatic decrease in wheel tyre life. This lifetime reduction led to an unacceptable increase in life cycle costs. Therefore Lloyd's Register Rail has proposed to NedTrain to investigate the possibilities of improving the wheel tyre life. Three improvements were determined as most promising and relatively easy to achieve: - Profile optimisation for Rolling Contact Fatigue (RCF) reduction - a new wheel profile has been developed with a better resistance against rolling contact fatigue of the wheel tread. The profile has been implemented on single deck intercity trains and shows an increase in wheel tyre life of 30%. - Selection of improved wheel tyre materials - combining information from literature and experiences of manufacturers five alternative wheel tyre materials have been selected and are now being tested in practice. - Optimisation of the maintenance strategy - an alternative, preventative maintenance regime has been developed. With this Scraping regime, during short term maintenance every wheel is reprofiled. Higher mileages are reached and savings on life cycle costs up to 50% and more have been achieved. Unplanned maintenance goes down with $30{\sim}60%$. The results from field tests, using a reference group for comparison, and preliminary results after implementation show that the increase in wheel tyre life that is achieved with this project is significant. The results will continue to be monitored using the asset management tool 'Wheel Watch', that was specially developed for this project and is also described in this paper.
