건설 프로젝트에서 수집되는 생산성 정보는 공사 진행의 효율성 파악, 작업여건 및 투입자원의 분석, 프로젝트의 성과측정 등에 활용될 수 있을 뿐만 아니라 향후 공사계획 수립에 있어 유용하게 사용될 수 있는 매우 중요한 실적자료이다. 그러나 이와 같은 생산성 정보의 중요성에도 불구하고 기존의 국내 건설 산업은 생산성 데이터의 수집 및 측정방법 등이 아직 체계화 되어있지 못하고 생산성 데이터의 활용도 미진하며 이로 인해 대부분의 공사계획 수립을 현장관리자의 경험과 직관에 의존하고 있어 계획 대비 실적에 대한 신뢰도가 그만큼 저하될 수밖에 없는 실정이다. 따라서 본 연구에서는 실제 건설 생산성 데이터의 축적을 통해 이를 향후 공사계획 수립에 유용한 실적자료로서 활용할 수 있는 건설 생산성 예측모델을 제시하고자 한다.

건설 생산성은 생산조직의 견실성과 생산 활동의 효율성을 평가하는 지표로서, 생산성의 측정과 분석을 적절하게 하는 것이 매우 중요한 요소이다. 본 연구에서는 이러한 건설 산업의 생산성을 분석할 수 있는 웹(Web)과 OLAP 구조에 기반한 시스템을 개발하기 위한 기본 연구를 진행하는 것을 목적으로 하고 있다. 따라서 생산성 영향요인을 선정하고, 웹(Web)과 OLAP 기반의 시스템 설계를 위하여 시스템의 모듈간의 정보 흐름에 대한 IDEF0 모델링과 각 조직별 주체간의 업무 흐름을 정의 하였다. 또한, 시스템 내부의 정보 흐름을 보여 줄 수 있는 ERD 모델링을 구축하여 생산성분석 시스템 구축을 위한 설계를 진행하였다. 이러한 시스템 설계를 기반으로 생산성 분석 시스템 개발을 위한 방안을 제시함으로써 시공 현장에서 현장관리자가 의사결정을 지원할 수 있는 체계를 구축할 수 있을 것으로 기대된다.

The construction projects contain a lot of variables and risk affecting productivity. The duration of the project must be recognized important as for quality, unit cost and safety. There is need for improving work efficiency by investigating relationship of works to prevent delay. This study focuses on analysing the delay factors of steel staircase system to suggest regression model that enables construction productivity estimation. The position of the observers and construction delay factors were expressed by the independent variable of the regression model and productivity was expressed by a dependent variable. This paper suggests quantitative productivity and it is expected that will be helpful estimating application in construction new technologies.

When various construction types of architectural construction are proceeded in order, the reinforced concrete construction is the frame construction which takes up the most important proportion among the construction process. Thus, the analysis of the effectiveness and productivity of the reinforced concrete construction is necessarily needed for smooth performance of construction projects. However, the conventional studies are performing the analysis of the productivity of only part(mould and steel) of the reinforced concrete construction and they have limitation in that they do not propose quantitatively the overall productivity of reinforced concrete construction.

Compared to the other industries, construction industry depends many parts of production activities on manpower. And also 3D perception on construction industry and the shortage of motivation in construction workers are the biggest reason to reduce construction productivity. So to solve this problem, the research of factors which affect more to improve the construction workers attitude in construction site will be needed. This research has investigated that the productivity and important factors was divided to economic factors, social factors, psychological factors. The result show that economic factors remain pre-eminent in influencing productivity, but that social factors and psychological factors appear to be of increasing importance in this construction industry.

Improving productivity in industries is a very critical issue, and improving labor productivity is especially important in construction industry, which is a labor-intensive industry. However, researches on labor productivity in construction industry are insufficient, and most of previous studies have limitations in terms of specificity and logic. In this study, fuzzy DEMATEL method was used to structural analyze of influence factors for labor productivity in construction industry based on previous researches and expert survey. The result of this study contributes to deriving priorities for improving labor productivity.

Productivity is an important factor of the construction's success and growth. However, compared to the other industries, the study of productivity in the construction industry is still insufficient. Even though the Cast-in-Place piles work is also important in construction process, the research on the productivity is not enough. So, it is necessary for the systematic research on the productivity of Cast-In-Place Piles Work. Therefore, the purpose of the study is to classify lower productivity's cause and find a way to improve these situations. This study will give the checklist for the further study of factoring and improvement of the Cast-in-Place piles work productivity.

The purpose of this study is to clarify the reality of labor and capital productivity in the construction industry through an industry-level approach and to analyze the relationship between labor and capital productivity using a Cobb-Douglas production function. According to the research results, the construction industry has shown a very high capital productivity, while labor productivity has kept up a low level during the 1980s and 1990s. The reason was because of the lack of skillful construction workers and the decrease of capital. Meanwhile, the construction productivity has greatly increased since 2000 when there was no change in wages. This was because of a large inflow of low-wage foreign workers while the amount of value added has dramatically increased due to the liberalized sale price of apartment buildings. According to the analysis by the Cobb-Douglas production function, the elasticity coefficient of V/L to K/L in the construction industry had decreased from 1.1663 in the 1^st period(1971-1988) to 0.4465 in the 2^nd period(1989-1997), and to 0.1664 in the 3^rd period(1998-2003). Such a result means that the allocation of labor has gradually increased while the allocation of capital has decreased. Moreover there was a big increase in allocation of labor after 1998 due to the excessive deterioration of capital. In conclusion, in order to raise the construction productivity and to avoid labor-intensive production methods, investment for capital should be more increased. In particular, new machinery and equipment that can actually substitute human labor in construction sites should be more developed and applied to construction sites.

The success of the domestic construction project is mostly judged by process and costs. It can raise the accuracy of the process and costs through productivity measurement and management. System which can increase the productivity and efficiency is required at this moment. The purpose of this study is to introduce the case of measuring productivity system using the Digital Pen System. To utilize Digital Pen System can raise construction productivity. This system is expected to more efficient to accumulation and utilization of construction site information.

Estimating the productivity of labor has relied on the experience and intuition of an estimator, or productivity data, such as standard in practical estimation. However, when new technologies and new construction methods employed in the construction industry, Dependence of a quantity surveyor's intuition is increased. This is because of the lack of a systematic methodology which models, estimates, and measures the labor productivity, Due to the historical productivity data is unavailable. Even thought project history data contains information that is important to predict the performance of a project, It can not provide valuable information to model, estimate, and measure the labor productivity. This is because 1) the absence of the productivity measurement system with consistency, 2) the difficulty of reusability of historical data collected. Therefor, this study suggests a methodology which build a productivity model by measuring the productivity of labor and collecting the historical data systematically. In addition, this methology is applied to develop a productivity model of shop-drawing and manufacturing process using descrete event simulation.
