The Multi-family Residential is one of the most famous building types for a rental property in the US. Often times it includes multiple residential buildings and some amenity facilities, including a clubhouse or leasing office, swimming pool, dog park, and garages. Since the building type is built for rental purposes, the construction planning is phased and it makes the project complicated. Detailed planning and execution are important for successful construction management. This paper provides some management practices that are applied to one of the multi-family residential construction projects in Phoenix, AZ. The Front End Planning (FEP) process performed by both owner and contractor is the first key to a successful construction project. Specifically, the early review of phased turnover strategy, grading, fire/Americans with Disabilities Act (ADA) compliance, and Mechanical/ Electricity/Plumbing/Technology (MEPT) will provide absolute benefit to the project. Second, using a scheduling method to control short-term schedules and long-term can provide the ability to manage the issues with agility. Third, material delivery and procurement dominate the both project schedule and cost. With this COVID-19 circumstance, it is hard to expect the material, equipment, and labor forces to be delivered on time with the contracted price. Managing floats are more than important to managing construction productivity. Risk management should work to share the risks fairly. Lastly, turnover is directly linked with the profit of the project for both owner and contractor. The communication between the owner and contractor to re-schedule the proper turnover schedule is important for the phased construction project.

The purpose of this study is to gather baseline data on perceived priority of residential choice and housing satisfaction rates among consumers with the aim of using this information for future planning. Self-administered questionnaires were provided to 196 studio-type multi-family housing dwellers in the City of Gwangju from 2009 Apri 5th to 29th. The collected data was used to conduct comparative and descriptive statistical analysis: factor analysis, t-test, one-way ANOVA, correlation analysis. The main findings obtained are as follows: Firstly, in relation to perceived priority of residential choice, dwellers identified seven factors as important. Secondly, in terms of housing satisfaction about a unit room, the respondents identified five factors as important. This study confirmed that there existed passive correlation between priority of residential choice and housing satisfaction among residents in studio-type multi-family housings in Gwangju. It is very necessary to project a studio-type multi-family housing close to transportation for easy access, avoiding commercial districts. Delicate interior and design will attract more female residents as well as fully-equipped parking lots for people who drive to their workplace. According to research on a degree of housing satisfaction, all respondents expressed dissatisfaction with "noise". Therefore, in dealing with construction plans of studio apartment units, from now on, sound proofing facilities are required to reduce the acoustic invasion of privacy, especially, for units with more than two people. In order to satisfy all the demand of residents in studio apartment units, we have to pursue systematic and succeeding research about a studio-type multi-family housing well-fitted for the actual circumstances of local area and suitable for longer stay. To sum up, more research and development will be required for high-class studio-type multiplex housing for sale in dealing with households with financial stability such as two-paycheck couples, so-called DINK, or a professional single person, in the future.

With increasing airtight building construction aimed at reducing energy consumption, indoor relative humidity is increasing which can lead to condensation and moisture damage in multi-family residential buildings. This has led to increased implementation of mechanical ventilation to control indoor moisture. However mechanical ventilation systems consume additional energy and generate noise. As this leads to occupant discomfort, it is necessary to select a ventilation system that addresses the energy and noise issues. This research measured the ventilation performance, energy consumption, and noise level of mechanical ventilation devices in multi-family residential buildings. TOPSIS, a multi-criteria decision making technique was used to determine appropriate ventilation strategies in addition to occupant ventilation system operation preference.

To investigate opportunities for wood frame housing and to activate wood frame house construction, trends of construction activities. preference about housing, and building codes related to wood frame housing were discussed. And two models of wood frame house were developed and construction cost was analyzed to compare with comparative masonry houses. The results obtained were as follows: 1. While 77.8% of people prefer single-family houses, majority of people(74.9%), ironically, possess multi-family houses such as apartments Wood work cost was ratio of 4% of total building cost. while wood material cost accounted merely for 11 % out of total building material cost. 2. Building code was not major barrier to residential house at height under 13m. The building code regulated major structural member and family boder wall of multi-family house to be built with fire retardant material. 3. The proper wood frame house was analyzed of town house or villa type locating in suburban of big city with hot ondol system for the upper middle class. 4 There was no difference in construction cost between western style wood frame house and comparable masonry house, but construction cost for Korean style wood frame house is 27% higher than that of comparable masonry house. It was necessary to reduce materials and cost down by prefabrication technique for both style of wood frame house.

EIFS system has the merit of low construction cost and shortening of construction period by easy-to-construct. For such reasons as mentioned above, it has been using across the board such as residential building, school, officetel, building remodeling and so on. It, however, has a drawback of generating plenty of combustible gases from styrofoam which is main material of it. In this regard, measures to prevent losses of life from combustible gases are needed urgently as fires on residential buildings applied EIFS caused human casualties resulted from combustible gases. With respect to the above, this study will analyze the risk of fires on residential facilities, such as multi-family apartment houses, schools and other buildings, applied EIFS which is the most frequently used as material of exterior wall and suggest countermeasure of it.

To accomodate increasing housing shortage in many cities, Korean Government has implemented various residental land development projects to provide more land for new housing construction. Most of the residential areas developed by these projects were used for multi-family housing units. Under this process, the size and location of the neighborhood service facilities in the development area were regulated by uniform standards. For this reason, the neighborhood service facilities were not able to be provided according to the household density but provided in minimum status required by these standards. Based on these considerations, this study aimed to evaluated residential land development project conducted by pubilc authority, one of the residential land development projects in Korea. Results of the case studies confirmed findings from literature review and proposed that existing regulations applied to these projects need to be amended not only to accomodata unique situation of each development area but also to enhance level of the dwelling environment. As ways to resolve these problems, this study suggests followings: (1) more flexible operation of the regulations, (2) inclusion of the socio-economic characteristics of the perspective resident in planning process, and (3) introduction of design techniques in the project. Finally, this study proposed future study directions in relation to this issue.

This research analyzes the residents' satisfaction for the pedestrian space of multi-family housing based on quality index. For this purpose, nine apartment complexes which were built after 2000, are selected and examined by user characteristics of composition factors of pedestrian space. This research also compares residents' satisfaction by evaluation factors of walking environment. The resident survey reveals that the composit type of apartment gives the highest satisfaction to residents followed by a courtyard type, and a straight type the last. In particular, residents show high satisfaction to pedestrian-only space in the case of the composit type of apartment building. The most important factor of walking environment on residential satisfaction is the separation of car and pedestrian path of main entrance. Above all, suitability of construction laws and regulations should be reviewed for safer and more amenable walking environment.

In response to the economic depression, the demand for fixed rent income has increased according to the easing construction regulations. it caused indiscriminated investment to stakeholders. This leads to oversupply in the multi-family Housing market and increases unsold housing and vacancy rates except specific area such as Gangnam-gu.In order to solve this issue, although studies on the optimization price of apartment houses has been conducted, the study is insufficient regarding on residential officetel. Therefore, the objective is to suggest a basic study on optimal price estimation model development by using probabilistic forecasting method in planning phase. To achieve the objective, first, variables are defined such as expenses, financial costs, income, etc. Second, causal loop diagram is suggested. Third, basic optimization prices estimation model is developed. In the future, this study can be used as one of decision making tools in planning phase of officetel development projects.
