Formwork layout is perceived as important due to its strong tie to site works. But, most formwork is done manually and influenced by worker's skill and thus, a lot of construction errors occur. The introduction of BIM (Building Information Modeling) enables acquiring more precise information on the building shape, dimension, structure, etc. than 2D-based drawings and thus, the increased productivity, such as reduction of workload and work times, and the economic efficiency, such as reduction of formwork types and form dimensions with the consideration of constructability, are expected. This study reviewed the previous studies and formwork layout systems to derive this study's differentiations and factors to be first considered for formwork planning were derived by analyzing priorities against consideration factors. Last, a flow chart and algorithm were developed to apply the derived factors to the formwork layout module.

The goal of site layout planning(SLP) is to maximize the productivity and efficiency of the construction by reducing travel distance and material handling cost and manpower. However, SLPs are static layout schemes, which cannot be reorganized during the construction process to correspond with errors, phase transition, changing working environments on the site. To solve this problem, researches on dynamic site layout planning(DSLP) are emerging. This preliminary study clarifies characteristics of temporary facility's variables to develop the vertical DSLP algorithm of high-rise building construction.

Formwork accounts for a large proportion of the framework in high-rise construction projects in terms of the duration and cost. Especially, slab formwork has a significant influence on these factors. However, the current selection of formwork method in general contractors depends on the decisions of few experienced engineers, and layout planning of the formwork in specialty contractors requires lots of time by different floor types. As a preliminary study for developing an optimum layout model in slab formwork of high-rise building construction, this study proposes the process of the optimum layout model and determines a fitness function for use of the genetic algorithm aimed at table formwork.

There have been numerous researches on Nak-An village in Jeollanamdo, one of the most representative traditional castle village in Korea. Most of them have dealt with general and physical architectural scale and features separately. Therefore this study aims to understand the compositional characteristics of building layout and exterior space and the relations between street system and dwelling unit of folk houses in Nak-An village. The study examined houses of ordinary people in Nak-An village constructed before the village was not affected by foreign influences. 36 folk houses in Nak-An built from nineteenth century to early twentieth century and believed to have few physical changes from the original floor plans and architectural forms were the subjects to be analyzed. The most popular types in building layout are "Open L"and "Open U". The most typical orientation of main building is Southwest. The favorable entry into the dwelling lot is from the side. The street system in the village consists of main streets of South-North, resulting in dwelling lots with North-South axis most general. This site condition forces the entry into the lot from North main street and the side access to the main building. From these findings, the building layout and the entry into the dwelling lot of folk houses in Nak-An are strongly related with street system and conditions of dwelling lot.

As building space constitution and layout are critical for satisfying the building owner and users, their optimization is so important in the design process. However it's not always simple to set up objective criteria for the space layout optimization for different requirements and the architects mostly depend on their own experience for these. This study is to suggest a way to make up for this issue by referencing and deducing the space layout based on the given BIM space information and existing knowledge. For this purpose, the Space Syntax is applied to extract the information from a space model and an Expert System is used to make the best use of the relevant knowledge. Based on the Integration indexes for all the spaces, we could compare the space layout alternatives and determine the best selection for different accessibility conditions.

Most of the recent studies on Seowon have been done just in terms of classification of general kinds of building layout, so there are a few things ignored such as the way they were arranged, the compositional process of buildings etc.. Although the classification of types itself is meaningful in the study on Korean traditional architecture, there has been some limitation in deep analysis of each style. The aim of this study is to find out the characteristics of the building layout and space composition of Dodong-Seowon with the viewpoint of the process of changes of it during the time through the survey and analysis on both the existing site layout and the measuring unite of scale applied to the original construction of each building. Hierarchical order scheme was considered in the design of the space proceeding from the entrance to the main space and of the building position, axis and the roof heights of buildings.

건축공사에서 먹매김 공정은 건물의 구성요소를 계획된 위치에 정확히 형성하기 위한 기준이 되므로 높은 정밀도가 요구된다. 최근의 건축물 규모 증가 및 숙련공 부족 추세에서 먹매김 공사는 로봇 기반의 자동화 기술 도입을 통한 생산성 및 품질 향상 요구가 크게 나타나고 있으며, 특히 가장 선행되는 골조공사 먹매김 작업의 중요도 및 자동화 필요성은 더욱 크다고 할 수 있다. 이러한 배경에서 본 연구는 건축물 골조공사용 먹매김에 적합한 시공 자동화 시스템 개발 방향을 제시하고자 한다. 기존 유사 기술 고찰을 토대로 하여 5가지 구성기술과 17개의 세부 기술요소를 도출하였으며, 전문가 설문을 통한 중요도 평가를 수행하였다. 설문 결과, 열악한 주행 및 작업 환경에 대응하기 위한 주행부 및 마킹부 기술이 가장 중요한 구성기술로 파악되었으며, 이러한 환경에서 정밀도를 확보하기 위한 제어기술과 전반적인 프로세스의 자동화기술의 중요성이 높게 나타났다. 본 연구 결과는 향후 보다 실용적이고 효율적인 자동화 시스템 개발에 기여할 것이다.

This study is to analyze the building layout of traditional government office building in Chungchong province with Chungchong-do regional maps and Eupjis(邑誌) being compiled in the late Chosun dynasty. The building layout of government office in Chungchong-do is followed in the wake of the spatial structure, Sam-Jo(三朝, three reign) and Oejeon-Naejeon(外殿-內殿), of Chosun dynasty palace. The planning principle of Sam-Jo at government office, Dongheon(東軒) territory for rule administration corresponds to Chijo(治朝) with a local governor who is the ruler, as for the Naea(內衙) territory which a family of him and he lives in, it is corresponded to Yeonjo(燕朝), and in the job space of Ajeon(衙前), it is corresponded to Oejo(外朝). As for the application of the inside and outside principle of provincial government office, Dongheon is corresponded to Oejeon and Naea to Naejeon. A compositive and an approach axis of government office in Chungchong-do is correspond with Dongheon in the center, and these axes form an central axis and an entry space of government office included Oesammun(外三門) Naesammun(內三門) Dongheon or Naea. Because an essential performance of provincial government office is provincial administration, the layout configuration of government office is a function, which is an expression of an official institution.

Construction robotics is rapidly forming a market in conjunction with the development of sensing and artificial intelligence technologies. The layout work for accurately constructing the shape and dimensions of the building frame requires high accuracy and precision, and is one of the high demands for productivity and quality improvement through construction automation. Thus, as a preliminary study, we derived the elemental factors and performance requirements for developing an automated layout robot. In addition, alternatives on driving and marking units were investigated based on literature review and practioner's interview. The result of this study will be used as a basic data for the layout robot design.

Determining the layout of temporary facilities that support construction activities at a site is an important planning activity, as layout can significantly affect cost, quality of work, safety, and other aspects of the project. The construction site layout problem involves difficult combinatorial optimization. Recently, various artificial intelligence(AI)-based algorithms have been applied to solving many complex optimization problems, including neural networks(NN), genetic algorithms(GA), and swarm intelligence(SI) which relates to the collective behavior of social systems such as honey bees and birds. This study proposes a site facility layout optimization algorithm based on self-organizing maps(SOM). Computational experiments are carried out to justify the efficiency of the proposed method and compare it with particle swarm optimization(PSO). The results show that the proposed algorithm can be efficiently employed to solve the problem of site layout.
