Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment preservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. For the building or construction project, its possible impact on environment during construction work and after completion must be predicted at its design phase, which will result in the completion of the architecture convenient for human being with its environmental pollution reduced to minimum level. In this study, the checklist of environmental factors was suggested, which should be taken into account at its design phase in conducting the construction work. Proposed checklist was linked with the developed web-based system for the convenience of users like designer and construction manager, etc. It is expected that the checklist suggested by this study will help the designer and construction manager to continue the steady development from the environmental viewpoint during the design phase.

In construction projects, it is common to exchange documents using email because of convenience. In this study, a method extracting and organizing block information automatically based on email was developed. This method is composed of document exchange and archiving processes, which are difficult to manage and vulnerable to loss. Therefore, this study aims to develop a solution that can automatically link email and block information. The block data components are designed to derive from email exchange and user-additional input information. Also, automatically generating blocks process including extraction and conversion of information was proposed. This solution can lead to promote the convenience of project document management in terms of identifying the document flow and preventing loss of information.

In this study, Site Investigation Program of cut slope is developed using related techniques and experience got from practical application of Inventory Survey Program of cut slope in work for last 4 years. The Site Investigation Program is designed to can be loaded to the Mobile PC for convenience of carrying in filed, convenience of data input and revision, application of diverse programs, convenience of confirming data and facility of establishment of real-time database system using wireless communication like Inventory Survey Program. Also, for connection with Inventory Survey Program, it has a same work process and can establish real-time database system of almost data obtained in filed using stability analysis tool loaded in this program. Application of this developed program is expected to be an opportunity that can contribute to development of slope investigation and database system area using IT techniques.

플라스틱보드드래인은 연약지반 개선공법의 하나로 경제적이고, 시공이 편리하며, 품질관리가 쉬워서 널리 사용되어 왔다. PBD를 지면에 수직하게 40m 깊이로 타설하는 PBD장비는 인출하중에 대해 안정적이면서 설치와 이동의 편의성을 위해 경량화 되어야한다. 본 연구에서는 구조해석을 통해 이전 장비와 철골구조에 대한 응력분포로 안전성을 평가하였다. 그리고 중량을 줄이면서 강도를 증가시킬 수 있는 철골구조를 제안하였다. 본 연구의 결과로 이전의 장비에 비해 중량이 700kg 가벼운 안전한 구조를 얻었다.

This study is to understand fallible point on the step of design, construction and management, and suggest an improvement measure for the convenience of elderly through the field survey. The field survey on convenience facilities for the disabled of Senior Welfare Center in Chung-Buk Area was performed on approach to main entrance, parking lot, main entrance area, entrance door, passage, stair, elevator and toilet. It was discussed that barrier free design should be considered of main user's group and use pattern. Consequently, important points requiring circumspection at the step of design and construction was suggested.

In order to secure the practicality of services using drones, improve on-site operability, and improve the convenience of aircraft maintenance, it is necessary to develop a drone station that can be safely stored while ensuring charging performance. Therefore, a total seven points of improvement were derived through laboratory experiments after the development of the first prototype, and an improved second prototype will be developed in the future based on the preceding processes.

For the target goal of Zero-energy House construction in 2025, the government announced that the insulation regulations will be continuously enhanced. It has been predicted that high-performance insulation materials, such as vacuum insulation panel (VIP), should be used to decrease the thickness of outer walls. The aim of this study was to evaluate the performance of adhesively fixed external insulation and finish system (EIFS) with VIP. The energy performance of a base model with conventional internal insulation system and three alternatives of EIFS with VIP were analyzed by three-dimensional heat transfer simulation. Construction cost and convenience of each alternative were also evaluated and compared. As results, effective alternatives in terms of each performance as well as overall performance considering the weighting factors of each performance were suggested.

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.
