Due to increasing competition of construction companies, it is required to optimize the management of construction projects and "lean" concepts are rapidly spreaded in construction industry. Steel work accounts for a large proportion in construction work, and a variety of attempts to efficiently perform steel work has currently made. And since rebar (Engineer-to-Order) can be engineered through design once order is placed, it gives the great impact on construction, thus, entire management is required. The purpose of this study is to present the method to increase the efficiency of field processing method of steel work in terms of lean construction. Once we examine process of steel work and identify the flow, we would like to analyze which processes should be improved through value analysis approach and present the improvement plans. Also, this study examines cases of field processing and factory processing, and it identifies the waste factors in the procurement process. Finally, this study would like to present the result of analysis from the perspectives of value. The rebar delivery process is divided into several steps and the duration of every step is surveyed. Using duration data, VAT (Value added time) can be calculated for analyzing the efficiency of the process.

As a construction technique is developed recently, the construction space and construction period are considered to important matters. Especially, in case of construction period, several method is proposed for strength control in the construction field. However there are very little strength control models for application of internal condition. The purpose of this study is to develop a strength control model for application of variety internal condition at construction field. The results are as follows ; 1) According to the results of compressive strength of concrete evaluated by logistic curve and proposed curve, proposed curve is applicable of construction field because there is similar relation with logistic curve. 2) It is shown that the construction period is shortened by reduction of the formwork removal time, because a predicted compressive strength of using the new curve is higher than the proposed compressive strength of standard.

건축공사 현장에서 공사관리를 수행하는 현장관리자의 작업능력은 프로젝트의 성공여부에 많은 영향을 미친다. 따라서 본 연구는 국내 건축공사 현장관리자의 작업능력에 영향을 미치는 요인을 파악하는 것을 연구의 목적으로 한다. 작업능력은 작업능력지수를 통해서 측정하였으며, 직무스트레스는 한국형 직무스트레스 측정도구를 통해서 측정하였다. 현장관리자의 작업능력은 직무스트레스가 높을수록 떨어지는 것으로 나타났다. 또한 운동, 종교보유도 현장관리자의 직무능력에 긍정적 영향을 주는 것으로 나타났다. 본 연구결과는 현장관리자의 작업능력을 향상시키는데 도움을 줄 수 있을 것으로 기대된다.

The construction arbitration field has developed considerably since the latter half of the 1990s. Through analysis of construction arbitration cases taken up by KCAB, this paper intends to show the present condition and the improvement direction of construction arbitration in Korea. The number of construction arbitration cases filed at KCAB has been increasing rapidly after 1997, but recently the rate of increase has tended to decline. From 2000 to 2003 the number of arbitration cases increased 23％ each year, on average, but in 2003 the increase was only 7.6％. In the very beginning, public construction claims made up the majority of all construction cases, however, civil construction claims are increasing gradually. The arbitration amount in the construction field is very high, owing to public construction claims. For example, the arbitration amount per case was 5 billion won, on average,. in the public construction field. It is shown that the claimants of arbitration are mostly constructors and the main reasons for making claims are to demand payment for construction and payment for additional work. KCAB investigated the performance status of arbitration awards. The voluntary performance rate for awards in construction arbitration is nearly 80％ and in 11％, a suit was filed to appeal the arbitration award. In spite of the development of construction arbitration, some improvements are requested. There have been arguments about the effectiveness of selective arbitration agreement in the General Terms of Construction Contract. This has caused a decrease in arbitration cases, so improvements in this dispute settlement clause need to be made. Enforcement of arbitration awards is granted by the judgment of a court. Resulting from this, appeals for arbitration awards are not allowed, however, up to three appeals for the enforcement of awards are allowed in court. As such, the enforcement system for arbitration awards needs to be improved and simplified.

Since the introduction of the C.M(Construction Management)system in the Basic Law of the Construction Industry in 1997, the recent arrangement of construction management engineers in public sector buildings has generally been based on architecture·civilengineering·machinery·landscaping, electricity, telecommunication, fire fighting by the number of M/M(Man and Month). In the field of engineers arrangement in each field, the arrangement of M/M according to the workload of architecture.civilengineering.machinery.landscaping and electricity is inadequate causing conflicts and C.M among construction management engineers. Therefore, this study aims at basic research that is used to identify the problems through the questionnaire and to prepare future improvement plans.

When construction engineers perform their work in the jobsite, they have to record as-built conditions in the project log (Data Collection). On the other hand, the engineers often have to refer to the construction documents when necessary at the job faces (Data Access). The practice of Data Collection and Data Access in the jobsite can be greatly enhanced by utilizing mobile computing with wireless communications. In this paper, two cases of mobile computing applications for construction field management are presented; Mobile Specifications System and Mobile Data Collection System. The demonstration of the process for developing two mobile applications is the primary purpose of the paper. The problems and issues involved with adopting mobile computing for construction field are also presented. The simple information framework for mobile computing has been also proposed as an outcome of the research. As for development tools, readily available relational database and wireless network have been used. The use of commercial mobile broadband was examined for data communication where local area network is not available.
