Construction companies find it increasingly necessary to reduce the cost as the construction market has been suffering from a depression and the industrial environment has been changing fast lately. The cost cut demands the productivity management of the field operations, which can be made feasible by assigning an appropriate number of managers on the construction site. However, previous studies are focused on the labor productivity and construction companies take into account only the revenue per worker in organizing the staff. The purpose of this study is to research the model for calculating the field management manpower in accordance with the characteristic of project and site conditions which are usually considered in the beginning of the construction project. The data about apartment building projects of domestic large constructors and factors related to them were statistically analyzed. The results of this study can be used to calculate the necessary field management manpower in accordance with the characteristic of project.

In order to solve housing shortage, an apartment has been built and supplied in large quantities in Korea. As such a result, the apartment became a typical housing type in Korea. However, the housing became vulnerable to accommodate rapidly changing life-style & life-cycle of koreans and was lost the concept of Korean traditional housing for inheriting and developing Korean traditional culture. Therefore, this paper aims at eliciting of design elements for development on standard model of long-life housing with durability & flexibility based on data derived from housing consumers's questionnaire survey and expert's opinion surveys. We expect that the standard model developed on the basis of open building applying support & infill elements will be used as a standard model for planning future long-life housing with capacity.

Purpose: The current study analyzed trends in thermal insulation performance with aging, and condensation characteristics caused by the former. Method: Thermal insulation and condensation prevention performance of an architecture were assessed using Temperature Difference Ration Inside, or TDRi. Subjects of this quantitative analysis in thermal insulation performance change due to aging included recently constructed apartments and aged apartments older than 40 years. Time series comparison and analysis were conducted to observed changes in the thermal insulation performance and condensation characteristics. Result: Analysis showed that wall insulation performance degraded with aging regardless of fortified insulating material usage or insulating material type, which caused increased danger of condensation. In addition, when fortified insulating material was installed on the connection between the walls, insulation performance degradation was lower compared to cases in which fortified materials were not used. In all cases from 1 to 10, the rate of thermal insulation performance degradation increased after 20 years of aging.

Recently, underground spaces can be usually applied to the alternative of land use for parking. However, lack of window and natural light are among the most cited drawbacks associated with dark image of underground. If underground parking lots are designed to be positive and safe environment for people, openings for daylighting will play a significant role. The natural light and unobstructed view to outdoor are main elements to create optimal underground parking lots. This paper focuses on investigating the actual day lighting conditions and evaluating the day lighting performance of openings as potential lighting resources. For the study, the field measurements and Questionnaire surveys are conducted. And then, the day lighting performance of underground parking lots based on opening geometry and orientation are evaluated by scaled model experiments. As results, the feelings of safety and orientation of underground parking lots are improved by openings for day lighting regardless of the sizes. The required illuminances (daylight factor 0.5%) for underground parking lots can be satisfied in the skylight opening ratio of 4% or more.

Apartment housing is a widely-spread type in Korean housing market. Nevertheless, it has caused serious problems such as traditional community corruption, unsafe structure, defects and litigation from noise. Noise, especially in concrete structure for apartment housing, is hardly controlled in proper to prevent sound transmission between upper and lower families with existing system. In foreign countries, there are floating floor system to enhance the noise control performance in multi-family housing. This study is to examine the impact sound insulation performance of floors according to the different P'yong and Layers by field measurement in highrise building.

Green Standard for Energy and Environmental Design (G-SEED) is evaluates the eco-friendliness of the building as an abjective means. Study in green building is made actively, and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED and checks the reflection of requirements. This study will be a reference of future revision of G-SEED. Score of items are divided into low and high score items. These items should be reflected appropriately in the standard through the score adjustment. Some requirements proposed in previous studies was reflected, while substantial requirements was not reflected. Proposed improvement requirements are classed as to establish specific standards, strengthen standards, propose a new evaluation method to existing items, and add new items.

As a series of studies about natural ventilation driven by wind in basement parking lots of apartment, the influence of opening size and surrounding buildings on ventilation rate was analyzed. Natural ventilation in underground parking lots almost rely on wind than temperature difference. To investigate natural ventilation driven by wind, wind tunnel tests by using scale model and tracer gas method were conducted. $CO_2$-gas concentration was measured, natural ventilation rates were calculated. The experimental results showed that the natural ventilation rate is more reliable to wind direction and surrounding building than opening size and distance between buildings. It was verified that surrounding buildings play a principal role in increasing air flow rate by accelerating wind speed, and growing turbulence intensity. And it showed that ventilation performance is able to be increased by oblique wind to entrance ramp than head on wind in underground parking lots with surrounding buildings.
