  • The stringing load was added to tower design that consider the active load in 765kV transmission line construction. The nominal auxiliary members of steell tubular tower arm were altered into stress members by means of three dimensional design analysis method. 765kV transmission line construction also use self-standing tower that does not install temporary wire which support the section tower placed between drum field and engine field when stringing process.

  • Recently, with the increasing of construction works, large construction equipment are used to reduce the term of work and labor cost in construction field. Therefore, construction equipment noise has caused much annoyance for a number of dweller in nearby construction field and it has become a very serious problem in our living environment. Nevertheless, in our country, adequite guidelines for the construction equipment noise are very deficiency because of the lack of basic data and insufficient research works. From this point of view, this study attempts to survey the characteristics and prediction of SIP piling noise. On the basis of measurement value, we analysed about prediction possibility of SIP piling noise by computer simulation.

  • Recently, construction vibration has caused annoyance for a number of dwellers in nearby construction field and that induced from operating of large construction equipment, has become a very serious issue in our living environment. But, construction vibration standard of our living environment. But construction vibration standard of our country is efficient. Especially, directly blow method(diesel piling method, oil pressure method, etc) has caused much problems of highly impactive vibration. Construction works, in order to solve these problem, will be used SIP(Soilcement Injected Precast Pile) method of low vibration equipment. In this point, this study attempts to survey on the characteristics of piling vibration by SIP method for various earth conditions in construction field. And this study intends to get the basic data to establish a standard about construction vibration.

  • Construction equipment noise has caused much annoyance for a number of dwellers in nearby construction field and has become a very serious issure in our living environment. Therefore, in our country, a practical solution and a better method of reducing construction equipment noise are highly required in construction field. Practical solutions for the construction equipment noise, however, are very difficult because of the poorness of basic data and insufficiency of the existing research. Especially, in order to establish the sound insulation plan about pilling works noise with high sound pressure level and impactive, a real situation of sound characteristics about the noise of pilling works in foundation work demands more detail investigation. In this point, this study attempts to survey the characteristics of attenuation and propagation of construction equipment noise in pilling work using SIP(soil-cement injected precast pile) method with casing. And this study intends to get the basic data for establishment of a standard about construction noise.

  • The construction industry kept lower level of the technology and productivity improvement than any other kinds of industry. But in most analysis of previous construction work which promoted the productivity of construction, the analysis process has only developed by the economical efficiency or the time studies through work sampling in construction field, So We suggest motion analysis as a tool to solve these problems. Spacially, this study find out productivity improvement method of steel frame fabrication works with using motion analysis. If the result of this study were to be applied to the actual construction field, it will be of great help for Building Construction Automation.

  • The construction industry is highly dependent on human resources and changes the degree of completion of construction work depending on the level of performance of engineers. As women's social advancement has recently expanded, the construction industry is also experiencing a large influx. Therefore, it can be seen that not only male engineers' ability to carry out work but also female engineers' ability to carry out work is important. Therefore, this study investigated the actual work conditions and work performance capabilities of female engineers and presented them as basic data for the construction of work capability improvement measures.

  • The purpose of this study is to ensure an amicable material quality control in the construction site through investigating a process which can impact the construction material quality. For it, a worker interview and questionnaire survey was conducted through a direct field visit. The visited construction sites are composed of 79% construction site and 21% engineering site. As the respondents of questionnaire survey, the quality control workers were 72% of total respondents. Next, the construction worker, handymen, field representatives and others formed 7%. The interview with the quality control staff was conducted with the items including the construction site quality control guide, incoming inspection and material management. Through this survey, the problems of quality control by progress phase were derived. It could be known that the management and measures by each phase were urgently required. It also was indicated that a selection of low-priced material caused by low price bidding could badly impact the construction and safety. Also, in relation to the opinions such as the insufficient quality control and heavy work-load, the improvements are required. For the effective quality control in the construction site, the material quality control procedures suitable for the phase of construction progress must be presented in the present quality control. Also, the standards for it need to be established.
