The purpose of this study was to identify and categorize the space use characteristics of the university professor's office. The data were recorded and collected through the physical trace method. Acture Measurement. Photograph, sketch and CAD drawings were used to trace 118 professors offices at Yonse-University. The analysed features were the user characteristics, the size, characteristics of space (such as composition, layout and furniture arrangement), the appliance and the instrument characteristics. To categorize the 'space use' characteristics. 6 variables were used: 1) the territorial characteristics, 2) the spatial relationship between professor's territory and entrance, 3) the layout type of work area, 4) the spatial relationship between professor's and assistant's work area, 5) the arrangement of table, and 6) the completion of sofa set. The results of this study are expected to be used as a basis for the development of design alternatives for the most typical university professors' office.

Recently, the structure is higher and larger, so that the application of high-strength concrete is increased, And as the development of construction skills, it is possible to place during the winter. Concrete work during winter is indispensible to shorten time of completion and cut costs. When concrete work during winter is placed, it has anxiety that concrete freeze at low temperature. As repetition of concrete's freezing cause reduction of durability, it is necessary for mixing to pay attention to air content and W/C ratios. Accordingly, in this study, we estimate the frost resistance by air content and W/C ratios, and development of strength after early-frost damage in the high-strength concrete during the cold weather. In this study, it could be confirmed that factors which were air content, W/C ratios and early curing period, affected on the frost resistance.

According to relevant laws, in the case of a construction project with a total construction cost of 30 billion won or more, a post-construction evaluation must be performed after completion. In addition, a post-construction evaluation report must be prepared and entered into the Continuous Acquisition & Life-cycle Support(CALS). As a result of reviewing the currently accumulated post-construction evaluation reports, since the report is not standardized, it is difficult for public project owners to write the report. It also hinders the post-construction evaluation and management center from verifying contents, analyzing data, and deriving meaningful results. In order to improve the convenience of the public owners who must conduct post-construction evaluations and the work efficiency of the center, evaluation factors were standardized and a standard post-construction evaluation report format for road construction was developed in Excel. Through this, the data in the reports will be effectively accumulated, managed, and analyzed, so that meaningful results will be produced and be helpful in future construction work.

Excavation is most commonly used activity in all construction projects. All contracting agencies prefer to use bigger and heavier excavators and dumpers on site to do excavations if quantity of excavation is huge. Estimation of required number of excavators and dumpers for completion of excavation could be rather a tedious process involving repetitive calculation on which professionals spend their valuable time. As the Information Technology is highly involved in construction section there os need to have IT model for estimation of number of excavators and dumpers. The developed model is useful to calculate required equipments within short period of time. The purpose of the developed IT model is to save the time and efforts of the construction professional. The paper discusses about model which can be used on site to estimate numbers of excavators and dumpers required for completion of certain quantity of excavation within the given time. The calculation considers various existing formulas and method to generate the output. This information could certainly be useful in planning equipments on construction project sites. The tool is user friendly where any non IT background person can use it on construction sites.

건설 프로젝트의 단위작업을 기반으로 발생되는 노무자의 작업시간은 진행된 실적물량 정보와 연계되어 생산성 정보로 가공되고 이는 다시 해당 단위작업의 공정관리와 연계됨으로써 프로젝트의 계획 대비 실적을 비교 및 분석할 수 있는 근거자료로 활용 될 수 있다. 또한 이러한 작업정보(노무자의 작업시간 및 실적물량 정보)는 잔여 작업 일정에 대한 예측 및 작업조 운영계획 조정 등 공정관리와 관련된 다양한 원천데이터로 제공될 수 있으며, 실적자료로 축적되어 향후 유사 프로젝트의 공사계획 수립에 유용하게 재활용될 수 있다. 본 연구의 목적은 PDA, 바코드, 웹 기술 등을 활용하여 단위작업을 기반으로 발생되는 작업정보를 효과적으로 수집하고 이를 생산성 정보로 가공하여 공정 및 공사관리 업무를 지원하는 전산화 시스템을 개발하는 것이다. 개발 시스템을 통해 분석 및 축적된 생산성 정보는 단위작업의 공정과 연계되어 잔여작업 일정 예측 및 작업조 조정 등 다양한 공정 지원데이터를 제공할 수 있으며 지식관리 차원에서 향후 유사 프로젝트의 공정계획 수립시 매우 유용한 참고자료로 활용될 수 있을 것으로 기대된다.

The construction industries are facing problems of productivity, quality of work, safety, and the completion of projects in time. In construction industry a worker is exposed to hazardous environment, and has to do more physical work, effecting his health and also productivity. The automation and robotics can offer solution to many problems of the industry. In the past the major barrier to construction automation is the lack of electronic components and systems. This is solved now with the development of information technology, and the current obstacle is the high cost of automated systems, shortage of public money for R&D, and problems of acceptance. The robots employed in construction have followed the same concept as those employed in manufacturing. However, construction industry requires a different kind of robot compared to manufacturing Industry. The robots are stationery and product moves along the assembly line in manufacturing sector, but construction robots have to move about the site because buildings are stationary and of large size. The construction robots must function in adverse weather conditions, including variation in humidity, and temperature and increase the overall construction productivity rate. The major objective of the paper is to review the existing applications of building robots and to assess their implementation in building industry. A case study is considered for the implementation of robots for the painting work of the University Building at Saifabad PG College of Science, Hyderabad, India.

The defects that are bound to arise in most construction projects cause disputes among the contracting parties regarding the defect warranty liability (DWL)guaranteed by the retention of the contractor's performance security at the end of the performance period of the contract. Most current projects involve a multiple-tier contractual relationship, causing the liability for some defects to overlap. In addition, many construction projects are made up of multiple detailed work types which an expert hired by the owner inspects the part completed by the contractor and pays an interim payment. However, after the completion of work, the contractor will still hold the defect warranty liability. In a scenario in which the work is delayed due to reasons for which the owner is responsible, the defect warranty liability period is also increased, imposing an additional burden on the contractor. In this study, basic research was carried out with the goal of reducing problems related to defect warranty liability Problems related to defect warranty liability cases and the nature of the defect warranty liability period were investigated. Possible solutions to the problems caused by the DWL that were suggested include the separation of the negligence liability period and the strict liability period, as well as the introduction of a retention money system.

Naval ships are complex weapon systems which play the integrated performance by system integration of many kinds of weapon systems and their leading ships are usually not disposed after test and evaluation but militarised. Then, strict project management is required for naval ship building projects by identifying problems early and by taking prefer measures in time against unexpected situations encountered in the process of the projects. EVMS is a project management system which can manage the schedule and the budget of a project concurrently and estimate the project's time duration and the cost at project completion. In this paper, the applicability and usefulness of WMS is studied for a assumed navai ship building project, in the environment of monetary fluctuations such as price index, wage increase rate and exchange rate.
