In general, construction projects in the past have been seeking to improve their quality through project management from the design and construction stage to the completion stage based on the accumulated technical standards, experience, and performance. However, the recent winds of environmental change, such as the 4th industrial revolution, are having a great impact not only on the technical aspect but also on the management aspect in the construction industry. In this situation, social expectations for productivity improvement and fair trade that are required in each field of the construction industry are acting as a motive for change in the construction industry. In a situation where the government is also making continuous efforts to reorganize all regulations such as related laws to respond to such changes of the times, this study is based on the legal regulations related to construction project management. management method was reviewed. Among the various management methods, this thesis examines various problems related to the calculation of service charge for apartment housing construction project management in the public sector, which is the most sensitive to the ordering party and related industries, and where conflicts of interest are frequent. A study was conducted to derive it.

A Study on the Growth Stage of City Center According to Residential Development : Focusing on the case of Daegu City

The purpose of this study is to “grow in Jung-gu, the central city of Daegu, as the four stages of urban development, as Leo van den Berg argued, due to the concentration and dispersion of the population between the central city of Daegu and the surrounding regions. Under the hypothesis that there will be stages”, we tried to identify the stages of growth in the city center. The research method analyzed the number of households in housing construction according to the Daegu Metropolitan Housing Statistical Yearbook. First, the geocoding program was used to convert the address of an apartment complex into coordinates, and then a distribution map by year of housing complex construction was created to analyze the location change process. As a result of the study, first, it was confirmed that Daegu Metropolitan City is currently in the process of suburbanization and reverse urbanization as apartment housing construction is actively built in the outskirts of downtown such as Suseong-gu and Dalseo-gu, and second, the growth process of Jung-gu, the downtown area of Daegu, is changing into three stages. In other words, until 1993, the first stage, the centralization stage, until 2003, the second stage, the congestion stage, and after 2003, the third stage, the re-centralization stage, showed an S-shaped growth pattern.

공동주택 건설사업에서 조경 감리의 품질관리 현황과 개선방안 연구

This study was intended to present measures for the improvement of the apartment house landscaping supervision system by examining the adequacy of landscaping supervision, which is aimed at improving the quality of landscape plants and facilities in apartment house landscaping sites. Additionally, this study aims to identify the problems occurring in the process of the performance of landscaping supervision and to provide the evidence for legislative activities and revision of the laws currently being pushed forward for the mandatory deployment of apartment house landscaping supervision personnel. The results of the analysis showed that no landscaping supervision personnel was deployed to apartment complexes with less than 1,500 households and that the landscaping comprised 19% to 46% of the entire construction process. The civil engineering firm performed the landscaping supervision, which made it impracticable to fully focus on the construction quality in the field of landscaping. The quality control in terms of landscape plants revealed differences in quality control, depending on the competence and experience of the civil engineer supervising the personnel, where the landscaping supervision personnel was not deployed. The apartment houses landscaping supervision activity index was analyzed, and the results showed that the supervision activity index for apartment house A was 72.0, B was 70.4, and apartment houses C to G ranged from 38.7 to 46.9, which suggested that the difference in quality control, process control, and technical support affected the construction quality and occurrence of defects.The improvement of landscaping process quality control and process management will be carried out more smoothly and the rate of defects will be drastically reduced if the landscaping supervision personnel placement threshold is lowered from 1,500 households to 300 households in complexes. The results of this study are expected to be useful in promoting and re-establishing the landscaping industry based on the improvement of construction quality in the field of landscaping in connection with the construction of apartment houses.

Паевые инвестиционные фонды недвижимости как инструмент коллективных инвестиций в России и США

The objective of the paper is to analyze the activities of Russian mutual funds of real estate and the development of the collective investment industry. To do this, we compare the results of the activities of the Russian mutual funds of real estate with analogues existing in the United States (REITs). We show that such mutual funds of real estate take an important place in the Russian financial system. But the average annual profitability of the closed-end investment fund of real estate in Russia was 6.14 % during 2013–2017, which did not exceed inflation (7.73 %) and the yield on bank deposits (7.86 %). The USA’s REITs profitability over the same period was 9.9 %, which is several times higher than inflation (1.32 %) and deposit profitability (0.6 %), which explains the popularity of this collective investment instrument among the population in the United States. The assets of the mutual funds of real estate in Russia are many times less than the analogues in the USA. The advantage of REITs is that their shares are freely traded on the stock exchange. For the purchase or sale of shares of the closed-end investment fund of real estate, you need to catch the moment of the beginning of the formation or termination of the fund's activity, respectively, and shares are rarely circulating on the exchange. For the period 2015–2017 inflation in Russia drops significantly, reaching 2.51 % in 2017. Together with it, the rates on deposits gradually decrease. If this trend continues, investment in the closed-end investment fund of real estate will become more attractive. The factor of growth of the Russian mutual funds of real estate could be the amendments to the Federal Law No. 214 “About Participation in Shared-Equity Construction of Apartment Houses…”

Planning Standard of the Public Pedestrian Passage based on the Theory of Endurance Limit Focused on the District Units Plan for the Apartment Construction Project in Daegu

The purpose of this study is to suppose the standards of public pedestrian passage planning, when some existing roads are closed because of an apartment housing construction project. For this purpose, the theory of endurance limit is introduced and an empirical testing is performed. The results of the analysis are as follows: First, the endurance limit of increased walking distance is showed in the range of 25~150m (with a mean of 94m and a standard deviation of 31m). Second, the factors such as pedestrian s age, walking purpose, and total walking distance affect the endurance limit. Based on the results, we propose a planning standard for apartment construction project: 1)When walking distance increase by more than 70m because of the project, we should consider making a public pedestrian passage. 2)When walking distance increase by more than 100m because of the project, we should make a public pedestrian passage. With this standard, it can be expected to reduce excessive planning and to increase the effectiveness of the plan.

Developing a Construction Duration Estimation Model to Ensure the Safety in Apartment Housing Construction Sites

Construction process acceleration due to the unreasonable construction duration frequently leads to construction accidents. In order to ensure the safety in construction sites and to avoid inevitable construction process acceleration, there is a need for objective standards to determine the appropriate construction duration for each construction process earlier in the process. To achieve the goal, a construction duration estimation model was developed by exploring those factors that affect the construction duration. Various statistical techniques, including multiple regression analysis and analysis of variance (ANOVA) were also conducted in order to predict proper construction duration for apartment housing projects. The results of the study will make it possible to avoid inevitable construction acceleration, and thus minimize the potential of construction disasters/accident.

Long-life housing means a housing which structural members (Support) such as columns and floor are maintained for a long period of time and the housing can be used for approximately 100 years by replacing components (Infill) such as walls and furniture. The government established「Certification standards of long-life housing construction」on December 24, 2014, requiring the long-life housing certification for construction of apartment houses for over 1,000 households. However, it is necessary to prepare an incentive measure which could be granted to construction related personnel and housing owners due to the effectiveness of such system and recognition that the initial construction cost of long-life housing is high. The purpose of this study is as follows. First, the reasons and necessity of long-life housing cost increase for each construction company, housing owner, infill component manufacturer and designer which are long-life housing related personnel are determined. The direction of incentive grant for supplying long-life housing based on the determined items is established. The result of this study is as follows. First, a special treatment which is higher than the alleviation of construction standards according to the previous ordinance is necessary for construction companies to secure the business feasibility. Also, incentives such as the provision of service space and wide balcony are necessary to improve the preference level of parceling out. Second, financial incentives such as financial support for housing purchase, reduction and exemption of tax (acquisition tax and registration tax), and support of maintenance cost are required for house owners. Third, it is essential to increase opportunities to participate in the market for infill component manufacturers by applying additional points for PQ. Fourth, it is needed to provide compensation for additional human resource and time at the time of designing to designers by preparing the long-life housing design cost standards.

시뮬레이션 기법을 활용한 소음저감형 알루미늄 거푸집 공사의 소요품 산출 방안에 관한 연구

Recently, a series of noise-reduced aluminum forms are being used as a solution for minimizing the noise which occurs essentially when installing or dismantling the conventional aluminum forms in apartment housing construction. The primary objective of this study is to propose the number of man power per unit (<TEX>$men/m^2$</TEX>) required for construction of a nose-reduced aluminum(Hi-tech System) form that is the most frequently applied in the domestic construction industry using simulation technique. For this, the detailed work processes required for installing and dismantling the noise-reduced aluminum form were analyzed and the man-power per unit was finally calculated by applying the real time consumpted for completing each work process on site to the established cyclone model. Using the proposed number of man-power per unit for the noise aluminum form construction, it is anticipated that owners and contractors can more accurately estimate and predict the predetermined price and the construction expense for the noise-reduced aluminum form construction respectively.

공동주택 전용 갱폼 인양 자동화 기술의 개발 - 구조적 안정성 및 타워크레인 양중부하 분석 -

갱폼(Gangform)은 기준층 설치 후 반복사용이 가능하여 기존 합판 거푸집에 비해 공기단축이 가능하고 높은 경제성을 확보할 수 있는 시스템 거푸집이다. 또한 거푸집의 처짐량이 작고 외력에 대한 안정성이 높은 장점을 지니고 있다. 그러나 갱폼의 운반 및 인양작업은 타워크레인의 동력에 전적으로 의존하고 있으며, 갱폼 인양작업을 위해 공동주택 골조공사 6~7일 사이클 중 1일의 공기를 차지하는 등 전체 골조 공기에 있어 큰 비중을 차지하고 있다. 이러한 문제점을 해결하기 위해 국내외 관련 업계를 중심으로 갱폼 인양과 관련된 다양한 연구 및 기술개발 노력이 수행되어 왔다. 특히, '공동주택 전용 갱폼 인양 자동화 기술 개발에 관한 연구'는 타워크레인의 동력원에 의존하지 않고 별도의 인양장치에 의해 갱폼의 인양작업을 가능할 수 있도록 하는 개념 디자인을 제안하였다. 이에 대한 후속 연구로써 본 연구에서는 구조해석 프로그램을 활용하여 선행 연구를 통해 제안된 갱폼 인양 자동화 기술의 구조적 안정성을 해석하고, 실제 공동주택 건설현장의 공정데이터를 적용하여 갱폼 인양 자동화 기술 적용 시 기존 타워크레인의 양중부하 감소 효과를 분석함으로써 제안된 공동주택 전용 갱폼 인양 자동화 기술의 기술적 타당성을 제시하고자 한다. Gangform, compared to the traditional forms, is a systemized form which can reduce construction duration and cost by the advantage of using it repeatedly. However, transportation and climbing process of the Gangform is highly dependant on the performance of tower crane. Gangform climbing process takes one day out of six to seven days of a structural work cycle. Tower cranes can not be used in other lifting works when they lift the Gangform during the structural work cycle, causing the delay in the construction project. Numerous efforts and researches have been done in domestic and international industry to solve such limitations of Gangform climbing process. Especially, "A Study on the Development of Automatic Gangform Climbing System for Apartment Housing Construction"has suggested a conceptual model which can climb the Gangform system without a tower crane. In this paper, the technical and economical feasibilities of previously proposed Automatic Gangform climbing system are examined by evaluating its structural stability and lifting load reduction effect.

Gangform compared with conventional wood and steel form is systemized form which has a capability to install and dismantle form at a time without repeating to assembly and disassembly small members. Gangform compared with ACS has some problems such as 1) Tower Crane load increase, 2) increase in safety incidence during climbing Gangform, 3) decrease in detachment operation productivity, 4) stop work due to climate impacts, and 5) decrease in labor cost, productivity, quality. A conceptual design model of automated Gangform climbing system is suggested for apartment housing construction to show its technical/economic feasibility and workers` safety while increasing operation productivity and concrete quality.

Improvement of the PVC Window Frame Installation Method Integrated with Gangform and Field Applicability Analysis

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.

건설 공사의 안전성 향상을 위한 충돌방지형 시스템 플라잉넷의 개발

Flying net should be installed on every 3 or 4 construction floor from 8m above ground according to the rule. In the apartment housing construction, flying net installation work has been recognized the most dangerous work among the whole works because a small mistake of labors might make their death accident. Sub-contractors specialized in flying net have been developing various flying net types. However, most works of installing flying net as working with the developed system are performed outside the apartment housing, so that the risk of fall in works of installing supports and unfolding net is still high. Furthermore, as using the previously developed flying net labors might bump into the frame or the wire rope for supporting so that it makes secondary accidents. The objective of this research is to produce the proto-type of anti-collision flying net system based on the result of problem analysis on the installation and detachment process and suggest the improved anti-collision flying net system, which is able to improve safety and field applicability by conducting field experiment and analyzing performance.

Policies for a Low‐Carbon Society in Japan

ABSTRACTThis article discusses possible policies to realize a low‐carbon society at the local level, focusing on population, housing and transport in Shiga Prefecture, Japan. Within this context, in order to substantially reduce local demand for automobile based transport in the long term, it may be important both to influence commuting patterns and to increase the population density of the city. Compared with the price elasticity of gasoline consumption in overall Japan, Shiga's elasticity is high. Thus, revising the automobile fuel tax system in some areas can drastically reduce fuel consumption and alter travel patterns. Whilst this may limit travel demand through commuting, we also recognize that residents of densely populated areas are often dissatisfied with the limited living space and with the lack of contact with nature. Policies to attract and promote the construction of apartment houses with adequate living space and that have increased amenity access to the natural environment are therefore important. This is the case both from the perspective of reducing greenhouse gas emissions and from the perspective of securing the vitality of the city. Based on our estimation and analysis, Shiga prefectural government has been setting up several policy measures to promote the formation of a compact city, to provide for public transportation and to promote bicycle use. However, the momentum fuelling urban sprawl and an automobile‐dependent lifestyle are difficult to change in reality. Copyright © 2011 John Wiley &amp; Sons, Ltd and ERP Environment.

Conceptual Design and Feasibility Analyses of a Robotic System for Automated Exterior Wall Painting

There are approximately 6,677,000 apartment housing units in South Korea. Exterior wall painting for such multi-dwelling apartment housings in South Korea represents a typical area to which construction automation technology can be applied for improvement in safety, productivity, quality, and cost over the conventional method. The conventional exterior wall painting is costly and labor-intensive, and it especially exposes workers to significant health and safety risks. The primary objective of this study is to design a conceptual model of an exterior wall painting robot which is applicable to apartment housing construction and maintenance, and to conduct its technical·economical feasibility analyses. In this study, a design concept using a high ladder truck is proposed as the best alternative for automation of the exterior wall painting. Conclusions made in this study show that the proposed exterior wall painting robot is technically and economically feasible, and can greatly enhance safety, productivity, and quality compared to the conventional method. Finally, it is expected that the conceptual model of the exterior wall painting robot would be efficiently used in various applications in exterior wall finishing and maintenance of other architectural and civil structures such as commercial buildings, towers, and high-rise storage tanks.

A PDA and wireless web-integrated system for quality inspection and defect management of apartment housing projects

In general, quality inspection and defect management in apartment housing construction are one of the major factors that general contractors have to consider for improving customer satisfaction and raising their images in the industry. However, many cases show that prompt and efficient actions are not made due to lack of the number of on-site quality managers, excessive workload for crews to meet deadlines, and inefficient communications among project participants. The primary objective of this research is to propose a computerized Quality Inspection and Defect Management System (QIDMS) which can collect defect data at a site in real time using Personal Digital Assistant (PDA) and wireless internet, and effectively manage statuses and results of the corrective works performed. Authors expect that the effective use of the proposed QIDMS would significantly improve communication efficiency among the related participants and help quality managers systematically manage and accumulate useful data that would be utilized as a reference in future construction projects.
