Develop A Commissioning Process And Template In Building Project For Large-Scaled Construction Company

This study aims to establish building commissioning process for large-scaled construction company, and develop the commissioning template in accordance with each phase. The purpose of this paper is to develop a practical, systematic, professional template for commissioning for a large construction company. In addition, commissioning of buildings is the main subject of performance verification of Heating, Ventilating and Air Conditioning and Refrigeration (HVAC & R) systems that require equipment and control, so we focus on verification of HVAC & R. Large-scaled construction companies in Korea are transforming from general contractors to Engineering, Procurement, and Construction (EPC)s, and it is expected that the role of building commissioning for the objective quality assurance of buildings will be important in the future. In addition, it is necessary to prepare for this, since it is impossible to properly respond in a timely manner to the contractor who must obtain final approval from a professional commissioning company before delivering the building to owner. In order to solve these problems, it is necessary to properly understand the submission documents and work system required by a professional commissioning company and to establish a work performance system to enable commissioning from the General contractor’s perspective. As the owner's demand for building commissioning increases day by day, a response to this is necessary, also, the commissioning can respond to the global warming crisis. The research team builds the commissioning template from plan to O&M phase, then, the template contained key documents and general document packages.

거시경제변동 전후 유동성이 주택시장에 미치는 영향 분석

과거 한국 주택시장은 주택건설업체들이 아파트를 건설하기만 하면 분양이 순조롭게 되었기 때문에 공급자 주도형 시장이었다. 이에 따라 한국 사업개발주체나 건설업체들은 주택사업을 매우 경쟁적으로 진행하였다. 하지만 1997년 아시아 외환위기 및 2007년 글로벌 금융위기가 발생하자 심각한 미분양사태가 발생하여 국내 건설업체들은 심각한 유동성 위기를 겪게 되었다. 본 논문은 시기별 금리 및 통화량과 같은 유동성이 주택매매시장 및 전세시장에 미치는 영향을 벡터오차수정모형을 통해 비교분석하는 것을 목적으로 한다. 이를 위해 본 논문에서는 서울시 아파트시장을 대상으로 연구를 진행하였다. 분석변수는 주택매매가격지수, 주택전세가격지수, 금리, 통화량(M2)를 활용하였다. 본 연구에서는 서브프라임 금융위기 발생 이전인 2001년 9월부터 2008년 9월까지를 Model 1로, 2008년 10월부터 최근 2015년 10월까지를 Model 2로 구분하여 비교분석하였다. 분석결과 먼저 주택매매시장의 경우, 가계소득을 향상시키는 장기적인 주택시장 정책을 수립하는 것이 중요하다. 주택전세시장의 경우, 전세공급량의 절대적인 부족에 따른 구조적 변동이 나타나고 있다. 이에 따라 국내 주택시장의 과도기적 변동이 시장에 미치는 충격을 최소화할 수 있도록 정책적 방안을 모색할 필요가 있다. In the past, once apartments were built by housing construction companies, their presale went smoothly. Therefore, the developer and construction companies in Korea were extremely competitive in the housing market. However, when the 1997 foreign exchange crisis and 2008 global financial crisis occurred, the quantity of unsold new housing stocks rapidly increased, which caused construction companies to experience a serious liquidity crisis. This paper aims at analyzing the influence of Liquidity on the Housing Market before and after Macroeconomic Fluctuations using VECM. The periods from September 2001 to September 2008 and from October 2008 to October 2015, which were before and after the Subprime financial crisis, were set as Models 1 and 2, respectively. The results are as follows. First, it is important to develop a long-term policy for the housing transaction market to improve household incomes. Second, due to the shortage in the supply of jeonse housing, structural changes in the housing market have appeared. Thus, it is necessary to seek political measures to minimize the impact of transitional changes on the market.

Performance indices for quantitative measurement of R&D results in private construction companies

As the investment in Research and Development (R&D) projects is increasing in private construction companies in Korea, the necessity to evaluate the effects of the investment in terms of company's finance is growing. However, there has not been an applicable system to properly and quantitatively measure the result and effectiveness of R&D efforts in Korea. In order to evaluate R&D results, R&D performance indices and their monetarily performance are required. Therefore, the purpose of this study is to develop performance indices capable of measuring the R&D performance quantitatively in private construction companies. To accomplish this purpose, development direction of performance indices has been established, through the analysis on current R&D measurement standards in major Korean private construction companies and through carrying out questionnaire survey. The development of performance indices has been implemented through the applicability evaluation of public R&D performance indices, the analysis on evaluation criteria in major Korean private construction companies, and the analysis on actual data of R&D projects of a Korean private construction company. 20 Performance indices are proposed by 5×5 matrix with performance areas (such as productivity, knowledge accumulation, application, publication, and standardization) and R&D purposes (such as product development, construction process/method development, specification development, standardization development, and others). The effectiveness of proposed performance indices was verified to be appropriate for R&D projects in private construction companies in Korea, through questionnaire survey with evaluation criteria such as comparability, measurability and validity. The primary contribution of this study is to establish private R&D performance indices essential to convert the R&D efforts into monitory term. As a result, they can help company executives to make decision to invest on R&D based on the reliable quantitation of R&D outcome.

Capital Structure Determinants among Construction Companies in South Korea: A Quantile Regression Approach

The present study empirically analyzed the capital structure determinants of 43 listed construction companies in Korea from 2000 to 2010 using multiple regression analysis. Specifically, the empirical analysis focused on changes in the coefficients of the determinants according to the leverage ratio quantiles of the examined construction companies. The empirical analysis found company and non-debt tax shield size to be positively related with leverage among construction companies, whereas profitability, growth, asset tangibility, and liquidity were found to be negatively related with leverage. The major results of the study are: 1) construction companies followed the static tradeoff theory in relation to size; 2) non-debt tax shields had quite limited effects on the capital-structure-related decisions of construction companies; 3) construction companies were found to follow the pecking order theory in relation to profitability; and 4) asset tangibility was estimated to have the opposite sign to that found in previous studies. These results were attributed to the characteristics of the construction business.

Truss rail method for punching shear strength of flat-plate slab-column using high-strength lightweight concrete

Large construction companies in Korea are particularly interested in technical solutions for high-rise buildings. In particular they are looking for ways to maximise economy by reducing the dead load and increasing the height of storeys in buildings. To achieve this, a flat-plate system using high-strength lightweight concrete has been proposed. To solve the weakness of the brittle failure of lightweight concrete as well as punching shear of the flat-plate system, this study developed a new shear reinforcement method. According to the shear reinforcement method and pitch intervals of shear reinforcement bar, the new method was assessed according to the first cracking load (Pcr) and displacement (δcr), the maximum load (Pmax) and maximum displacement (δmax), ductility index, reserved shear strength, economic feasibility and ease of construction. The test results indicate that with the new method, the specimen showed better shear performance and ductility effect in high-strength lightweight concrete than in normal concrete. Compared to the existing shear reinforcement method, the new method enhanced both shear strength and ductility effect as the pitch interval decreased. The truss rail method was able to reduce the quantity required and the production costs, while also improving construction efficiency.

PC부재에 의한 물류시설의 골조공사 개선사례 연구

물류시설은 층고가 높고 구조가 단순하며, 투자회수를 위한 조속한 운영이 필요하기 때문에 공기단축이 절실한 특징이 있다. 이에 따라 인력 및 원가절감, 공기단축을 기대할 수 있는 PC공법의 사용은 RC조에 비해 경쟁력을 확보할 수 있다. 그러나 국내의 시공사들은 RC공법에 익숙해져 있어, PC공법에 대한 부정적 인식이 팽배하며, 새로운 공법적용에 대한 노력이 미흡한 문제점이 있다. 본 연구의 사례현장은 단위기둥의 높이가 14m로 동일한 규격의 장주(長柱)가 110본 소요되는 현장으로 RC공법을 이용할 경우 시공성, 경제성, 공사기간, 안전성등의 문제발생이 예상된다. 따라서 본 연구는 RC조로 계획된 물류창고 현장을 PC공법으로 시공하여 인력 및 원가절감, 공기단축효과를 비교분석하고, 개선효과를 제시하는데 목적을 두고 있다. 향후 본 연구의 결과물은 물류시설 시공 시공기단축, 품질 및 시공성 향상, 안전성향상, 원가절감효과를 가져올 신공법개발 연구의 기초자료로 사용될 것으로 사료된다. As logistics facilities have a high ceiling height, simple structure, and the need for a quick return on investment, it is usually essential to advance the construction schedule of such facilities. Accordingly, PC structures, which require less labor, cost and schedule, can be more competitive than RC structures. However, most construction companies in Korea are familiar with RC structure design, have negative perceptions regarding PC structures, and do not sufficiently adopt new construction techniques. The structure that this research features has 110 columns that are 14 m high and are built to the same specification, and applying an RC design to the structure will lead to issues related to constructibility, economic viability, project duration and safety. Therefore, this study intends to feature PC design as an alternative to the RC warehouse design, and perform a comparative analysis of the reduction in labor, cost and construction schedule to highlight benefits. The research outcomes herein will provide inputs to subsequent studies on new construction strategies to advance the construction schedule, improve quality and constructibility, enhance safety and save costs.

This study is to consider a variety design methods and trends applied in the recent apartment housing design competitions for Sejong city. Because the Sejong city project housing design competitions were the most recent and foremost architectural firms and construction companies in Korea were participated in the Sejong city project. Therefore, the new design concepts should be used in the entry works of the design competitions, these analysis and valuations can be utilized for future and advanced housing estate design.

국내 건설기업의 경영 및 조직현황 분석

국내 건설기업들은 최근 금융위기, 미분양 주택의 증가 등 외부적인 경영환경의 악화로 많은 어려움을 겪고 있다. 이러한 경영환경의 변화에 대처하기 위하여 기업은 환경의 변화에 신속하고 탄력적으로 적응할 수 있는 효율적인 경영조직의 구성이 필요하다. 그러나 대부분의 기업은 조직에 대한 분석과 이해가 부족하여 사업 물량과 유형에 따라 경영조직을 구성하고 있다. 국내 시공능력순위 30위 이내의 건설기업들 역시 서로 다른 경영조직과 사업구조를 가지고 있으며 또한 각기 다른 경쟁력과 위기요인도 가지고 있다. 따라서 본 연구는 건설기업의 경영 및 조직현황을 조사하여 경영성과와 조직특성을 파악하고 효율적인 경영전략 수립과 기업의 경영조직을 구성하기 위한 기초자료를 제공하고자 한다. Builders in Korea are facing significant challenges in the midst of deteriorating market conditions resulting from recent financial crunch and slumping housing sales, etc. To address such changes in management landscape, enterprise organizations need to build an efficient corporate management organization than can ensure prompt and flexible response to changes in surroundings. However, most of them base their management organization on business type and volume due to insufficient understanding and analysis of organization. Top 30 construction companies in Korea have their own management organizations and business structures let alone different competitive edges and challenges. Therefore, this paper attempts to examine the current status of management and organization of construction companies to understand their operational achievements and organizational features in and effort to develop an efficient management strategy and provide inputs contributory to establishment of corporate management organization.

공동주택 상품의 고객서비스 개선 전략 연구

As customers are becoming increasingly important in corporate management, there is a growing demand for migration to customer-focused organizational structures. Unlike the manufacturing industry, the construction industry is non-iterative and non-standardized. As a result, a wide variety of materials, human resources, technologies and equipment must be mobilized in complex work activities to complete a structure. Consequently, surprises are bound to occur as such work activities progress. This paper intends to study a strategy that is designed to improve customer services for apartment building units. It aims primarily to focus on cost control and brand management. Housing tenants and industry experts are surveyed to collect input for issue analysis. In addition, the external circumstances and internal capabilities of major builders in Korea are analyzed, and a SWOT analysis is performed regarding market conditions related to customer service. These analysis results are utilized to develop a strategy implementation plan over different time frames, and the operational resources available for such strategy implementation are analyzed in order to forecast its performance. This research will facilitate communication between construction companies in Korea and their customers by proposing a customer service improvement strategy for apartment building units, and is expected to provide resource material for a strategic analysis of efforts to fully incorporate customer requirements

Comparison of strategies to improve indoor air quality at the pre-occupancy stage in new apartment buildings

Indoor air quality of new apartment buildings, which is known to cause Sick Housing Syndrome, has become a major concern among apartment residents as well as construction companies in Korea. Recently, the Indoor Air Quality Management Act, a regulation that limits concentration levels of formaldehyde and five volatile organic compounds in new apartment buildings, has been implemented. In this study, the effects of ventilation and decomposing agents were investigated and compared, which could be used at the pre-occupancy stage as solutions to high VOCs concentration levels in new apartment buildings. Six housing units were investigated under different conditions to assess the extent of the improvement in indoor air quality. The results demonstrate that ventilation is an effective way to control indoor air pollution caused by VOCs emissions, and the effect of decomposing agents on improving indoor air quality depends on the types of VOCs.

Knowledge asset classification in the construction industry

Construction industries have given the efforts to develop the knowledge management (KM) to manage their knowledge assets, but it is still required to clarify the definition of knowledge assets to the same extent as has been done in the other industries. Major construction companies in Korea have built their own knowledge management system (KMS), but the systems are simply limited to classify the existing information. The classification of existing information is a small part of KM, and it is then desirable to tacit knowledge assets such as company's development strategy, culture and etc. This study suggested a new concept of KM for construction. With the widened concept, this study derived some knowledge asset elements based on a literature review and the interviews with KM specialists in construction companies. The suggested criteria on knowledge asset classification can be helpful in the evaluation of knowledge assets of own. In addition, it can be applicable in the derivation of the knowledge maps for the development of KMS considering the relationship between the separate information, and the development of education programs.
