Deoksugung Palace Art Museum was built in 1938 as the first professional art museum in Korea. In 2015, National Research Institute of Cultural Heritage published a book on architectural drawings of this building. This book, called Architectural Drawings of the Deoksugung Palace Art Museum, consists of 646 sheets, 23 types of documents, as well as other historical letters. This paper focuses on the analysis of the characteristics of classicism in Architectural Drawings. It shows that every dimensions of drawings were controled by 3 partition composition through the analysis of architectural plan drawings, elevation drawings and even section drawings. Thus, Classicism for the museum is not about classical elements but the principle of composition of each elements for the construction. This paper further argues that Deoksugung Palace Art Museum exemplifies beautiful Classicism architecture which follows the principle of classical architectural composition.

Construction bid documents contain various errors or discrepancies giving rise to uncertainties. The errors/discrepancies/ambiguities in the bid document, if not identified and clarified before the bid, may cause dispute and conflict between the contracting parties. Given the fact that bid document is a major resource in estimating construction costs, inaccurate information in bid document can result in over/under estimating. Thus, any questions from bidders related to the errors in the bid document should be clarified by employers before bid submission. This study aims to examine the pre-bid queries, i.e., pre-bid request for information (RFI), from state DoTs of the United States to investigate error types most frequently encountered in bid documents. For the study, around 200 pre-bids RFI were collected from state DoTs and were classified into several error types (e.g., coordination error, errors in drawings). The analysis of the data showed that errors in bill of quantities is the most frequent error in the bid documents followed by errors in drawing. The study findings addressed uncertainty types in construction bid documents that should be checked during a bid process, and, in a broader sense, it will contribute to advancing the construction management body of knowledge by clarifying and classifying bid risk factors at an early stage of construction projects.

조경 도면이 전산화되면서 레이어의 표준화에 대한 요구가 증가하고 있다. 그러나 식재도면에 비해 조경시설물 도면의 레이어 분류 체계 정립은 늦어지고 있다. 이에 본 연구는 조경 시설물 전산 도면의 레이어 분류체계를 정립하는 것을 목적으로 하였다. 연구의 시작단계에서 "건설 CALS/EC전산도면 작성표준 v1. 1"과 "전자설계도서 납품지침"은 시설물 도면에 적합하지 않은 레이어의 분류체계로 되어 있는 것을 발견하였다. 10개 조경설계사무소에서 작성된 1,154개 도면을 수집하여 레이어의 작성 실태를 분석하였다. 분석결과, "건설 CALS/EC전산도면 작성표준"이 조경시설물 도면에 도입되지 않고, 레이어의 46%가 불명확하게 작성되고 있음이 밝혀졌다. ISO의 건설정보 분류체계를 적용하여 15개의 항목으로 구성된 레이어 분류 체계가 도출되었다. 본 연구에서 제시된 레이어 분류체계는 실무진이 참조하는 법률, 조경설계 기준, 조경공사표준시방서, 공공기관의 설계지침 등을 근거로 설정되었다. 이로 인해 새로운 레이어 분류체계가 조경설계 사무실에서 조기에 정착될 것으로 기대된다.

In the representation of buildings with continuous changes in the curved shape of the surface, countless plans or sections are required, or none of the traditional drawings can explain the geometry of it. In other words, in no case can an ordinary drawing achieve the efficient and clear communication capability which is inherent function of the drawings. As a result, the current architects are introducing their own way of drawing technique which is developed in accordance with a specific curved shape, construction method or company resources, but this is not what can be applied to other cases because it has not been ever shared or agreed in the industry. In this process, the drawing or construction of curved building has been recognized as the exclusive property of a specific expert, or the design and construction without the in-depth understanding of the technology have resulted in the appearance of poor buildings. Therefore, this study aims to present an elements and method that can convey shape information more effectively and clearly in the drawing representation of non-linear buildings and, thus, contributes to lowering the barriers to entry into the field by providing the information to be easily applied to related projects. In order to attain this goal, the drawings of recently completed projects of free form building are analyzed to reveal the method used to effectively express the shape information of the building and to derive new drawing elements that have not been applied to the existing drawings.

Extraction of fabrication documents is very important because it provides information related to tasks of fabrication and construction. Therefore, in the case of a prefabricated member such as a steel structure, it is necessary to improve the productivity of fabrication documents through 3D BIM. However, research and evidence data on direct comparison analysis of 3D BIM-based documents extraction versus 2D CAD-based documents extraction are hard to find. Thus, this study focuses on productivity analysis of 3D BIM based fabrication documents extraction. In this study, the productivity data of fabrication documents extraction for module construction of EPC project was analyzed. For the productivity analysis, a case study on the fabrication documents of Module A (1,965 sheets) and Module B (1,216 sheets) was conducted. Fabrication documents for each module include general arrangement drawing, assembly drawing, single part drawing and single plate drawing. Comparison of 2D CAD based fabrication documents extraction and 3D BIM based fabrication documents extraction, the productivity for the entire work was improved from 17 hours to 16 hours for Module A and 12 hours to 7 hours for Module B. Especially, the productivity of the assembly drawings, which occupies a large part of the fabrication documents, was improved by about 48.75% from the total time required from 281 hours to 144 hours.

It is very important to estimate accurate construction total cost needed early in the project. In the initial phase of the design, the project cost estimates are determined by total quantity from design documents and the variables that affect the calculation of the total cost of the project. In order to determine accurate total construction cost, the contractor has to produce detailed quantity information based on the drawings and specifications. The process of preparing quantification and cost estimation documents is still being worked out manually, and a lot of errors have been occurred in many cases. Recent advances in information technology have led to the BIM based quantity takeoff and cost estimation. However, there are some limits to the extent to which the current specifications for BoQ documents are computed from BIM model. This research analyze the current BoQ cases and analyze how to make quantity takeoff possible through BIM. The study defined five levels of quantity category that could be produced by BIM. Only about 40% or indirectly usable items can be used when information is extracted to BIM modelling. This is very insufficient to fill out the BoQ. The BoQ document structure quantity takeoff specifications should be simplified in order to BIM based cost estimation more efficiently.
