The cadastral administration is centered around cadastral maps. It is increasing that demand of the public for effective administration and higher quality of service through the development of application program of cadastral maps maintenance. Geo-Spatial Information System which is based on the graphic database of Yuseong-ku, Daejon City and the attribute database about cadastral information has been developed for effective maintenance and use in the part of map editing, public land price management and multi-parcel based work. In this pi-lot study, pointing out difficulties of database implementation and many experiences in the development of application program will be used effectively for further expansion of the automation of the cadastral administration.

Building information modeling (BIM) has the advantage of having been utilized for various scenarios through a single model. Although extracting 2D drawings from BIM is one of the advantages, there are many difficulties when utilized in practical work. Architectural detail drawings are an important factor for expressing interior finishing materials and complicated construction methods, as well as for cost estimations. However, creating detail drawings does not have a standard, and each design company establishes its own detail drawings, so it is hard to share or exchange information in the construction industry. Therefore, this study suggests a systemized method for making detail drawings, and explains how it can be utilized as back data for quantity take-off and construction expenses linked with BIM libraries.

스프링클러설비와 방화구획 구성요소는 화재시 매우 중요한 역할을 한다. 그러나 기존에 15층이하 아파트는 스프링클러설비가 없어 화재시 방화구획에 의존해야 되는데 방화구획 관련 설계, 시공, 감리가 미비하여 화재에 쉽게 노출되어 있다. 설비슬리브, 전선관, 덕트등이 방화구획으로 되어 있는 부분을 관통하는 경우 그틈을 시멘트모르타르나 기타 불연재료로 메우도록 규정하고 있으나 화재발생시 관통부를 메운 재료의 내화성능 부실, 균열, 탈락 등으로 화재안전성이 떨어진다. 현장에서의 설계, 시공, 감리등 대응하는 자세가 너무 허술하다. 설계에 방화댐퍼, 관통부 틈새의 내용이 반영 되지 않고 건축, 기계, 전기, 통신, 소방등 각 분야의 허가 도면에 도장이 날인되어 나타난다. 시공자는 잘못된 설계도면을 가지고 허가 도면이라며 도면되로 시공한다. 또한 실리콘, 우레탄폼등을 방화구획 관통부 틈새에 주입하며, 작업자도 비숙련자로서 개념도 없이 방화용실란트와 우레탄폼을 혼용해가며 작업을 한다.

This study suggests a methodology for automatically extracting placing information from 2D reinforced concrete details drawings and generating a 3D reinforcement placing model to develop a mobile augmented reality for bar placing work. To make it easier for users to acquire placing information, it is suggested that users takes pictures of structural drawings using a camera built into a mobile device and extract placing information using vision recognition and the OCR(Optical Character Registration) tool. In addition, an augmented reality app is implemented using the game engine to allow users to automatically generate 3D reinforcement placing model and review the 3D models by superimposing them with real images. Details are described for application to the proposed methodology using the previously developed programming tools, and the results of implementing reinforcement augmented reality models for typical members at construction sites are reviewed. It is expected that the methodology presented as a result of application can be used for learning bar placing work or construction review.

The construction cost is estimated based on the drawings at the design stage and constructor will find efficient construction methods for budgeting and budgeting appropriate to the budget. Accurate quantity estimation and budgeting are critical to determining whether the project is profitable or not. However, since this process is mostly performed depending on manpower or 2D drawings, errors are likely to occur and The BIM(Build Information Modeling) program, which can be automated, is very expensive and difficult to apply in the field. In this study, 3D architectural modeling was performed using SketchUp which is a 3D modeling software and suggest a methodology for Quantity Estimation. As a result, 3D modeling was performed effectively using 2D drawings of buildings. Based on the modeling results, it was possible to calculate the difference of the quantity estimation by 2D drawing and 3D modeling. The research suggests that the 3D modeling using the SketchUp and the calculation of the quantity can prevent the error of the conventional 2D calculation method. If the applicability of the research method is verified through continuous research, it will contribute to increase the efficiency of architectural modeling and quantity Estimation work.

As the amount of construction information used in the growing construction field increases, the importance of efficient construction field management has been growing. Accordingly, this study aims to identifythe application situation and possibility of BIM through theoretical examinations and domestic & overseas case studies of BIM, and attempts to suggest an approach to the formulation of an efficient construction field management model through the implementation of phase-oriented and cooperation entity-oriented analysis in the construction field. In the future, the conclusions of this study should be used to formulate an actual construction field management model and apply it in the field.

Traditional wooden buildings deform over time and are vulnerable to fire or earthquakes. Therefore, traditional wooden buildings require continuous management and repair, and securing architectural drawings is essential for repair and restoration. Unlike modernized CAD drawings, traditional wooden building drawings scan and store hand-drawn drawings, and in this process, many noise is included due to damage to the drawing itself. These drawings are digitized, but their utilization is poor due to noise. Difficulties in systematic management of traditional wooden buildings are increasing. Noise removal by existing algorithms has limited drawings that can be applied according to noise characteristics and the performance is not uniform. This study presents deep artificial neural network based noised reduction for architectural drawings. Front/side elevation drawings, floor plans, detail drawings of Korean wooden treasure buildings were considered. First, the noise properties of the architectural drawings were learned with both a cycle generative model and heuristic image fusion methods. Consequently, a noise reduction network was trained through supervised learning using training sets prepared using the noise models. The proposed method provided effective removal of noise without deteriorating fine lines in the architectural drawings and it showed good performance for various noise types.

BIM(Building Information Modeling) enables 3D model-base management for all information produced by construction project during its life cycle. Also as a national policy, BIM has been institutionalized as design criteria. But, on the matter of 2D drawing using BIM software (Revit Architecture), it has been recognized as difficult to realize the same quality drawing drawn by CAD. The purpose of this study is verifying the possibility of printable design drawing implemented by BIM software at the same quality of 2D shop drawing drawn by 2D CAD. Through the analysis of basic design elements of 3D BIM software and 2D CAD software, with the case of partial cross sectional drawing which is most faithful representation of the basic design elements, this study find out that the 3D BIM software can produce the same quality 2D printable drawing utilizing its implicit function.
