In order to calculate the interior remodeling volume of small-scale housing, it is necessary to directly measure the interior space, but in some cases, it is impossible or difficult to measure. In this study, a method of calculating quantity using indoor photographs in the SketchUp is proposed. Since the photograph for calculating the quantity is an indoor space, the reference corner should be included, and doors, pillars, and walls should be included. Placing the photo like a perspective view allows you to complete the entire model by creating a 3D model with lines you can refer to and converting them into real-size. In the completed model, the area can be calculated for walls, windows, floors, and ceilings, so the quantity of remodeling work components can be calculated.

Buildings that have been long neglected can suffer severe durability reduction due to factors such as rebar rust and concrete quality deterioration resulting from exposure to outside air. Furthermore, the issues associated with these suspended buildings, including safety accidents, social crimes, and environmental pollution, are becoming increasingly serious. This study investigates the current status of these buildings in the Jeju area, identifies the problems, and examines the durability of the structure in a specific location to assess the possibility of future use. Aesthetic surveys(visual and slope inspections) as well as non-destructive tests(compressive strength tests, neutralization tests, and rebar detection tests) were conducted to assess durability. The analysis revealed that the structure maintained satisfactory durability and the building's condition was good in comparison to the years of neglect.

The recent dormitory construction has been carried out in a build-transfer-release (BTL) method in which a special purpose company (SPC) builds dormitories and rents them for a certain period for financial reasons of universities. J University has several dormitories managed and operated by itself and entrusted to the SPC. This study aims to provide basic data that can be used for future dormitory remodeling or new building plans through the comparative analysis results of two types of facility satisfaction surveys with different dormitory management subjects. As a result of the satisfaction survey on dormitory students, despite the difference in the construction time of the dormitories, the survey confirmed that the evaluation of the dormitory was generally satisfactory and there was no significant difference.

It is difficult to build a only small housing in a urban or rural region because a owner meets lots of risks from planning, feasible study, estimation, design to construction. Conflicts or disputes owing to the improper communication between stakeholders like the owner, designer, contractor, sub-contractor, and manufacturer may cause the construction project to delay or stop. Thus, construction management can be a key success factor to the small construction projects. Many construction projects are built in Jeju. The middle and large projects have competent management personnels, but the small projects need a person or a company to help to complete the project goals. This research shows two case projects. One is the multi-family housing in an urban area and the other is single-family housing in a rural area in Jeju. A construction manager participates in both projects to support the owner. And the research proposes the client-customized construction management platform for small construction projects.

In order to improve the performance of cement mortar using combined sand of crushed and sea sands, this study analyzed its fundamental properties in accordance with replacement by recycled aggregate powder. The results showed that for binary aggregate with crushed and sea sands in a 6 to 4 ratio, the standard gradation was satisfied with replacement by less than 7.5% of recycled aggregate powder. Furthermore, as the replacement ratio of the recycled aggregate powder was increased, fluidity decreased and air content increased. Meanwhile, with replacement of less than 10% by the recycled aggregate powder, compressive strength increased 10 to 20% under the conditions of this research. Overall, it was determined that by replacement of 2.5% of recycled aggregate powder in binary aggregate with crushed and sea sand with poor gradation, optimum results could be obtained for satisfying the standard gradation and improving the fundamental properties of the cement mortar. It is necessary to evaluate the possibility of applying this result to concrete and actual structures.

Facilities with high risk of a disaster or requiring continuous safety management are designated as class-Ⅲ facility. In order to designate a class-Ⅲ facility, it is evaluated based on the safety status of the facility, the risk to the building users, and the number of years elapsed of the facility, etc. and this shall be referred to the actual condition survey for the designation of a class-Ⅲ facility. In the actual condition survey conducted to designate the safety status is calculated by the checklist based on the evaluation scores consisting of five stages each item, and is evaluated in three stages by 'good', 'careful observation', and 'designated review' through the average of the combined scores. Currently, the actual condition survey being conducted applies only structural stability, and the risk factors such as damage to the finish, the risk of cracking, and the type and weight of major structures are not included in the checklist for the actual condition survey, so even if experts think it is dangerous, scores cannot be reflected. Therefore, this study aims to analyze the problems of checklist of the actual condition survey for the designation of class-Ⅲ facility and to propose an improvement plan for the checklist for the actual condition survey.
