본 연구는 환경친화적 녹색임도 구현을 위해 1990년부터 2003년까지 시공된 충청남도 민유임도의 임도설계서를 검토하여 적용공종의 변화를 분석하고 평가하였다. 임도사업비의 변화추이는 사업연도에 따라 꾸준히 증가되었고 특히 환경친화적 녹색임도 구현을 위한 임도정책이 수립된 1999년과 2000년도에 사업비가 대폭 증가한 것으로 나타나 비교적 견실한 임도시공이 이루어질 수 있는 기반이 조성된 것으로 판단된다. 또한 토공사업의 비욜은 1999년 약 25.4%에서 2000년부터 2003년까지 토공사업비 평균비율이 18.5%로 감소된 것으로 나타났다. 하지만 토공의 비율이 줄어든 것과는 달리 비탈면보호공이나 구조물공의 총액은 상승하였으나 비율은 거의 증가하지 않은 것으로 나타났다. 이는 적용 구조물의 규격확대와 적용 물량의 증가에 따른 자재대의 비율과 제경비의 상승에 기인한 것으로 구조물공과 비탈면보호공에 소요되는 재료가 증가한 것으로 판단할 수 있다. 향후 공사비의 증가가 적용 구조물의 규격확대와 투입량 증가만으로 이어질 경우 임도시공 노하우와 경쟁력 약화를 초래할 수 있으므로 보다 다양한 공법의 적용과 개발노력이 요구된다.

The safety management cost system under the Construction Technology Promotion Act has contributed greatly to the prevention of construction accidents according to the chronological changes and social demand, but various problems have been pointed out. The biggest problem is that the safety management cost is earmarked very low because other items of safety management costs except for the safety inspection are not appropriately included in the actual construction site. Furthermore, it has been pointed out that it is difficult to settle the orderer due to the lack of specific use criteria. Therefore, in order to secure the proper safety management cost, this study is to estimate the actual cost by using of specification, quantity, material cost, labor cost for each type of the safety management item The results of this study were compared with the 71 cases of safety management costs in the safety management plan. In addition, analysis of unclear or unnecessary items in the current safety management cost and criteria and suggestions for improvement are provided. It is hoped that the results of this study will contribute to the rational safety management rate calculation.

This paper presents a study on the impact of variation of construction material prices on the feasibility of building projects in Vietnam. The paper makes use of Monte-Carlo simulation for financial risk analysis of net present Value (NPV) and internal rate of return (IRR). To well illustrate the influencing, a case study is presented. The research results show that there is a strong correlation between steel prices, gold prices, and $US exchange rate. Outputs of statistics also reveal that the concurrent variation of prices of cement, steel, sand, brick, formwork and stone has strongly negative impact on NPV and IRR of building projects. The results also indicate that the proportion of steel cost to total construction cost is 17.95% which is the cause of risks for the feasibility of building project in Vietnam. The paper stresses that feasibility study of building project must integrate the impact of construction materials prices in order to mitigate risks in developing countries as Vietnam.

Recently, Construction Projects are being much bigger and more complex. So the importance of Construction Planning and Management is increasing and increasing because of the Construction Projects is involved in a variety of construction-related subjects. Competitive of the Construction Industry decided Cost, Construction Duration and Productivity. But they were just focused on Cost Saving instead of Construction Duration and Productivity. However, they have to finish construction projects using minimum cost and duration with quality and function of required level for successful Construction projects. Thus, current high exchange rate and high period, it is clear to decrease construction cost and to do economic construction in huge Construction Projects and it means more advanced Construction Schedule Management needs for economic construction. But Construction Scheduling Planning, basic of Construction Schedule Management, adjusted contract period without Pre-Planning, just depending on experience and ability of Construction Engineer. Because of that, this study suggests new Duration Estimate Method using Stochastic Model in BIM Environment for advanced Construction Schedule Management. Existing Duration Estimate Methods are just modified wrong points of them or analyzed effective factors of construction schedule. However, New Duration Estimate Method is just consists of Stochastic Model and BIM Environment without existing Duration Estimate Methods. So, new method has creativity and specialty. After this research, it would be a great model in construction industry field.

려명거리 사업은 건설비용이 알려진 유일한 건축사업이지만 북한원으로 표기되어 그 규모를 짐작할 수 없다. 본 논문에서는 려명거리의 건설조립액을 기준으로, 북한 아파트 신축공사의 m²당 공사 원가를 산출하고, 이를 서울주택도시공사가 공개한 원가와 비교하여 남한과 북한의 건축공사비 비율을 산출했다. 그 결과는 160대 1이었고 이는 남북 공식 환율이 없는 상황에서 북한원으로 표기된 공사 규모 추정에 이용될 수 있으며, 향후 남북 공동으로 건축사업을 계획할 때, 상대의 화폐단위로 산출된 건축공사 원가를 이해하는 데 일조할 것으로 기대한다.

Recently on Value Engineering(VE) and Life Cycle Cost(LCC) social interests is increasing. The government Turn Key, BTL projects and public works projects, such as VE and LCC Analysis on the value and economic analysis is mandatory. And accordingly the VE and LCC analysis is underway for the various studies. However, there is a problem existing in the LCC analysis. Worth the cost varies according to the flow of time. However, the real interest rate during the LCC analysis of buildings in calculation time for interest rates and inflation are not considering the value of the flow. In other words, a few years using the average value of the deterministic analysis method has been adopted. These costs for the definitive analysis of the cost of an uncertain future, unforeseen changes resulting hazardous value. In this study of the last 15 years interest rates and inflation targeting by using Monte-Carlo Simulation is to perform probabilistic analysis. This potential to overcome uncertainties of the cost of building a more scientific and LCC Estimation of the probability value of the real interest rate is presented.
