  • There are certain types of construction that produces many defects during the construction of apartment buildings. It may be due to construction errors in the type itself, but more often, it is due to defects derived from other types of construction. Thus, to reduce such secondary defects and prevent fundamental defects in particular types of construction, academic research on the types of construction causing secondary defects should be actively conducted. In addition, as claimed in this study, the industries should work harder to improve the quality of the type of construction that causes secondary defects, rather than just trying to improve the ostensible problems. If the efforts of each sector are backed up, the disputes over defect repair in apartment building construction will reduce in general, which in turn will lead to a reduction in national loss within the construction industry.

  • Various types of fatal accidents are increasing in Korean construction work site. Simply repeated and conventional accidents as well as new types of potential hazards which are caused by large-scaled work, complexity and negligence of temporary structures in construction are increasing, so that analysis of fundamental causes are necessary to control the construction accidents. In this study 739 fatal accidents are informally classified by the types of work and work process. The classified items which are based on ANSI Z 16.2, are modified adapted to the construction fields and are given code numbers and are analyzed by the data-base program. The exact causes of various types of accidents are analyzed by the accident types, agencies and hazardous conditions and through the Cross-tabulation method in order to find out the cause between relevant accidents.

  • There are a lot of different types of noise from construction site and it depends on construction stage, equipment type and number of operating equipments. The problem is almost noise from construction site is high level and some kinds of noise levels are over 100dB. In addition, if construction site is located in downtown, there are a few options to reduce noise level. Therefore several site mitigation plans are developed to reduce different types of construction noises and it is applied in site and evaluated noise reduction performance in this study.

  • The prevention of safety accidents can be achieved through Harvey's 3E's: Engineering, Enforcement, and Education. On construction sites, however, enforcement and engineering did not prove to be valid ways of reducing the number of safety accidents, as enforcement and engineering have failed to overcome and/or supplement the realistic limits regarding the relatively lower education levels of construction workers and the communication issues with foreign workers. On the other hand, safety education can enable the advancement of safety management by enhancing the educational contents and their methods of delivery. To improve the efficiency of safety education via educational contents, this research conducted a qualitative and quantitative analysis on the validity of the newly educational contents by overviewing possible accident types in different work phases. Of the accident types identified by the qualitative analysis, neither highly important nor insignificant accident types were found, yet all the suggested types are found to be required. In addition, this study did not find any significant differences in the occurrence probability of safety accidents related to the level of importance of each type of accident. The qualitative analysis in this research verified that the suggested accident types can be valid, educational material that can take into account future safety accidents.

  • As buildings become higher, larger, and more complex, safety issues for construction workers working at such environments become more important. We analyzed 140 critical accident cases reported to the KOSHA(Korea Occupational Safety & Health Agency) for construction cranes and lifts by types of cranes and by patterns of accidents and causes. By finding out the accident's types and causes, we expect to develop an efficient measure for preventing similar accidents in the near future. The cases will be studied further and reexamined using the FMEA(Failure Mode and Effect Analysis) as a quantitative analysis method.

  • Multiple parties-owners, engineering and construction contractors, and suppliers involve the delivery process of capital facility projects in the construction industry, and each party obtains or provides their workforce, material, equipment, or service tied into specific contracts. Considering that construction projects are based on the contracted relationship between the parties and that contract types are one of the significant factors determining project success. it is critical for project stakeholder to select appropriate contract types for successful deliveries of projects. With these considerations, this paper assesses impacts of different contract types on project cost, schedule, safety, change, or rework. Analyzing data from real construction projects, the differences in project performance between two contract types, Cost Reimbursable and Lump Sum are measured and statistically tested to investigate if the differences are significant. For this analysis, performance metrics developed by Benchmarking and Metrics program, the Construction Industry Institute are used.

  • The main purpose of this study is to present the strategies for strengthening the leadership of field supervisors to effectively prevent construction accidents. To this end, first, this research study reviewed the meanings, functions, types and characteristics of the leadership of field supervisors in safety management activities on construction sites through the literature review. Second, the researcher investigated the types of supervisors' leadership and the level of field safety management activities through questionnaires. Third, the types of supervisors' leadership are categorized by that level. Fourth, the leadership type of field supervisors is suggested to effectively prevent construction accidents. Finally, the strategies to promote supervisors' leadership are developed.

  • Rework in the construction industry can adversely affect project cost and schedule performance. Based on direct rework costs recorded on 359 construction projects, this paper presents an assessment of the magnitude of rework by various types of projects and sources of rework. The results from this paper establish that on average 4.5% and 2.5% of actual construction costs were spent on rework for owner and contractor projects, respectively. Furthermore, this paper determines that the direct rework costs differ by project types and sources of rework. Finally, it permits the development of rework reduction initiatives. By quantifying and recognizing the different magnitude of rework, the industry can be aware of the waste from rework and develop effective plans for managing rework, ultimately improving project cost performance.

  • As construction project is becoming larger, construction progress and works are more various and complex according to recent Korean construction tendency. The growth of construction induces much pollution on the progress of construction and the problems due to the construction pollution are raised into social problem strongly, because it is increasing the need on the quality of lift and the desire of clean environment. This study aimed to seek far the effective solving plan of the construction popular complaints by surveying the real condition of construction popular complaints and analyzing the cause and tansaction period of popular complaints. For this study, the laws related and popular complaints were analysed focusing on the documents in low district offices of Gwangju from 2000 to 2004. As a result, the types of construction popular complaints were divided into 17 and the causes were as follows in order: crack and subsidence of ground(14.90%), infringement of private life(11.55%), noise(10.80%), infringement of a right to sunshine(10.07%) and breakdown(6.7%). Consequently, it is considered that these complaints are occurred by physical and environmental causes.
