In order to respond to environmental problems and to efficiently recycle resources, it is important to evaluate the amount of construction waste generated. In particular, the estimation of the amount of waste generated in the demolition work was performed based on the basic unit of waste generated per floor area. This study proposes a method using drones as a method for evaluating the amount of demolition waste in a wide area. In the simulated application, the field measurement results and the proposed method were compared, and the effectiveness of the building volume calculation using drones was confirmed. It was confirmed that the building volume can be calculated quickly in the additional pilot application.

Recently, in a field of cadastre, a computerization of cadastral map is in progress with great growth of GIS field. Also, the needs for the integration of land and building information are widely increasing for integral-management and its application of various land related information. In this study, it is constructed a 3D information cadastral map model that can make the integral management of land, building, connecting land recorders, building management ledgers, building titles, building pictures, and related attribute information.

In this search, by evaluating the field applicability of soil mixed pavement of Red mud is mixed into the soil mixed pavement field applicability, and tries to present the basic data about the site application of recycling of red mud and low carbon construction material to. As a result, the conventional soil concrete organization standards (SPS-KSCICO-001: 2003) meets the criteria for a bicycle road, making use of red mud, natural color as well as the natural loess is expressed.

The construction industry highly depends on each specialized manager which is essential to successful project. However, a new employee, who has just graduated from architectural engineering college, is requested additional education for 1~2 years such as On-the-Job-Training (O.J.T) to perform his/her professional job in construction site. It is wasteful for both construction company and the employee in terms of time and cost. The purpose of this paper is to investigate the required abilities and analyze the gap of demanded abilities between field managers and students. To collect data for analysis, questionnaire which uses Likert Scale has been performed to both parts. As a result, the analysis show that the graduate's abilities related to field experience get especially low degrees in compare with non-field experience factors. These results will contribute architectural engineering education in college to make more realized.

In apartment housing construction, window frame installation work, which is conducted after the structural framework, is very important, because its completion time directly affects the starting time of successive interior finishing works, as well as the overall construction period. Construction delays in interior finishing works might occur due to problems inherent to the conventional window frame installation method, such as the poor verticality of window frames, and the water leakage around them. The primary objective of this study is to analyze the problems of a 'Gangform integrated PVC window frame pre-installation method' based on its pilot test results. Next, this study proposes an improved conceptual model that enables the end users to enhance the field applicability of this method in terms of productivity, time, and cost. The field applicability of the proposed 'Gangform integrated PVC window frame pre-installation method' was also verified through a survey.

Dust scattering is one of the major problem for the residents living nearby construction field with construction noise and vibration. The dust scattering may inflict a considerable damage to psychological, spiritual discomfort to neighboring peoples. Therefore, the trouble of residents living nearby construction field have been increasing. Nevertheless, in our country, adequate guidelines for the dust scattering are not yet established because of the lack of basic data and insufficient research works. In this point, this study has researched its level of damage by conducting of the interview-survey which utilizing of questionnaire-paper asking for those staffs and workers to answer in the construction field, in order to grasp the damage extent of the actual condition effect and response against scattering dust in construction field. As the result, the occurring rate of dust scattering was appeared high compare with other constructing processes, due to utilization of construction equipment that operating at the fundamental basic construction stage, and it was turned out that presently the proper countermeasure and training against scattering dust in the construction site is insufficient. As for the solution mean against that, it is considered that with the better operation of construction site such as the installation of facilities for occurrence-restraint of dust scattering, frequent sprinkling of water, use of thermostat-covers, as well as those methods to be minimized of the occurrence of dust scattering must be contrived through the education for an attention how to use of construction equipment and training at the site.

Recently indoor air pollution caused by exposing hazardous chemicals (VOCs, formaldehyde) due to undiscriminated use of new construction materials and air-tightness to save energy is becoming a big issue. We have developed technologies to estimate the amounts of contaminants from constructions materials and method. We have further developed construction technologies to reduce and characterize these contaminants. The developed technologies were then refined to eliminate defects through considering field applicability.

Every year on a construction site safety scale of the crash of an accident, but the large and small, accounting for more than half. In Construction Field wearing safety belts for their safety, but the impact of fracture, including the risk of injury occurs. Accordingly, the death as well as by the crash, injuries that can reduce the size of the invention was driven by safety belts.

With the recent changes in building environments such as low-carbon green growth, there have been increasing demands for the new building system that is eco-friendly and can maximize efficiency such as the unit modular system. For the unit modular system, more than 80% of the whole process is carried out in the factory while in the field, mostly unit module assembling and finish work are done. Thus, the quality at the pre-construction stage when design and manufacturing are done determines the quality of the building as a whole. In the country, the unit modular method was first applied in 2003 to school buildings and has gradually expanded afterwards, but due to the lack of examples and related information as well as the small scale of modular manufacturers, its characteristics have not been sufficiently reflected in design, manufacturing and field constructions. This study, as an attempt to improve the design quality of unit modular buildings, points to the problem in manufacturing and field construction, compares and analyzes its causes, and suggests major points to be considered in the early stage of designing the unit modular buildings.
