  • In environmental impact assessment, noise impact assessment usually consists of three stages surveying the existing noise levels by measurements, predicting noise levels induced by construction works and predicting noise levels after the completion of project. When predicting noise level in urban area, this method does not consider acoustic phenomena like multi reflection, diffraction and absorption due to complex topographic configuration of building and terrains. For the purpose, a noise mapping tool is utilized to produce a series of noise maps, which are those for the present, for the works of construction and for the future. For accurate noise mapping, acoustical and topographic information is essential. Standard sound power levels and directivities of various construction equipments are required and scheduling of construction processes and locations of the equipments should be provided. In the case of exceeding legal limit, mitigation measures are applied to satisfy the legal limits and subsequent noise map is obtained and checked.

  • Recently, the scale of the construction work has been increased due to the revitalization of the construction industries. therefore, the demolition work in downtown areas is increased too. Amelioration districts are deteriorating rapidly since it followed the policy which allowed a large number of constructions in a very short period of time. therefore, the quantity of construction wastes and the designated wastes such as asbestos are increased. This study was classifying and analyzing the constructions in amelioration districts to estimate quantity of the designated wastes and the unit of the designated wastes. According to the results of this research, the average annual designated wastes was increased up to 2.59% in comparison with 2,779,334 ton in 2000, there came out 3,151,653 ton of designated wastes in 2005. For the appropriate disposal of increasing designated wastes, it is necessary to study exact estimation of the quantity of wastes.

  • Underground structures are built into concrete like a architecture and public works. Concrete has watertightness as such, But buildings are leaking from the cracks. Recently, construction method do a lot of close construction in the downtown area. So architects are using the method for the outer layer of a two-layer wall to save spaces. They have been using Top-down method and waterproof agent method and others to outer layer of a two-layer wall method. But, There are many leakage in underground structure from lack on requirements performance of materials. Therefore, I hope to test the outside Waterproof Method of Ground using Wire-mesh and Non-hardening Viscosity Waterproof. In addition to, I wish to apply as outside waterproof method for the section for the outer layer of a two-layer wall in underground structure.

  • In environmental Impact assessment, noise impact assessment usually consists of three stages-surveying the existing noise levels by measurements, predicting noise levels induced by construction works and predicting noise levels after the completion of a project. The distance-attenuation relation of a point source, which has been used to predict the noise level due to its simplicity does not consider complex acoustic phenomena like multi-reflection, -diffraction and -absorption due to complex topographic configuration of buildings and terrains. For the consideration of such physical complexities. a noise mapping tool is adopted to produce a series of noise maps, which are those for the present, tot the works of construction and for the future. For accurate noise mapping, acoustical and topographic Information is used. Standard sound power levels and directivities of various construction equipments are need and scheduling of construction processes and locations of the equipments should be provided. In the case of exceeding legal limit, mitigation measures are applied to satisfy the legal limits and subsequent noise map is obtained and checked.

  • This research is conducted on temporary street furniture, which is one of the significant factors that comprise the street landscape in modem cities. The primary purpose of this research is to present the guidance on direction of planning by examining the design and installation types of construction and screen fences usually established at construction sites for buildings, roads, parks and etc. The results are as follows: 1. The construction and screen fences at construction sites of urban areas used to be a mere tentative facility to prevent noise and safety accidents but have now incremented their roles to serve not only as a functional but also as an aesthetic element with a city view and harmonization with other elements taken into consideration. In particular, it is noticeable that, based on its unique feature of tentativeness, its role has developed to serve as street furniture that adds variability to the modem city. 2. There are two different types of screen fences: blackout type and transparent type. The transparent screen turns out to be used a lot at the construction site of building a skyscraper or differentiated building in downtown city area or in places where there are buildings of similar types and shapes located along the street in the vicinity of the construction site. 3. The actual cases of adopting the tentative construction and screen fences all at the same time as a single unit have been found in historically and culturally significant architectures with the screen design used to demonstrate the view after completion of construction or the characteristics of the architecture.

  • 도심지 지가가 높아짐에 따라 건축물의 공간 활용도에 대한 기대치가 높아지게 되었고, 건축물은 더 크고, 더 깊고, 더 높게 지어지는 방향으로 나아가고 있다. 이에 따라, 공사의 첫 단계이자 전체 건물의 기초가 되는 지하 공사는 그 중요성이 날로 더해가고 있다. 최소한의 비용으로 최단기간에 터파기 공사를 완료해야 하는 도심지 공사의 특성상 공사 관계자들은 지하 공사를 계획, 설계, 시공, 설계하는 과정에서 심혈을 기울이고 있다. 그럼에도 불구하고 지하 공사 전번에 걸쳐 있는 불확실성과 위험 요소 때문에 공사 실패 사례가 발생하고 있다. 더욱이 이러한 사고가 어느 정도의 경제적 피해를 끼쳤는지에 대한 보고나 연구없이 사고 사례만 알려지기 때문에 지하 공사의 위험성에 대한 경각심이 부족한 것이 우리나라 건축의 현실이다. 이런 사고를 타산지석으로 삼아 터파기 공사 공법을 선정하고 지하 공사를 이행하는데 있어서 하나의 지침이 되기를 바라면서 지하 공사 실패 사례가 과연 어느 정도의 경제적 피해를 발생시키는지를 개산견적 기법을 도입하여 추정해 보았다.

  • As the number of automobile registrations increases yearly, parking spaces that are located in downtown areas are increasing, and mechanical parking facilities are also increasing. Therefore, there is a high risk of accidents when installing and repairing a mechanical parking facility. In the preceding six years (from 2012 to 2018), the statistics that pertain to accidental disasters indicated that a total of 137 disaster victims were generated by the construction sector, 33 accidents occurred, and 10 people died. However, only the safety management items pertaining to accidents that occur during maintenance work and the use of the installed mechanical parking facilities are being studied; furthermore, there is no ongoing research with respect to the risk management that is conducted at the construction site. In 2017, the Korea Occupational Safety and Health Agency (KOSHA) announced the "Guidelines for Safe Installation and Maintenance of Mechanical Parking Equipment"; however, it is a safety guideline that is limited to the installation of basic protective equipment and to facility installation. There is no model for mechanical parking facilities that is indicated in the "Risk Assessment Model by Construction Industry Type", which is issued by the Safety and Health Corporation and is widely utilized for risk assessment in the construction industry; moreover, elevator installation work CODE N0: 22 is the only major example of a disaster. In this study, "risk assessment through a focus group interview" was performed, and data was derived from the "risk assessment of Article 41 (2) of the Industrial Safety and Health Act", which reflects the characteristics of the construction industry based on AHP analysis. The results of this study can be utilized for the risk assessment that is conducted during the construction stage of mechanical parking facilities.

  • There are several ways to solve parking problem in the downtown One of them is to manage parking efficiently, that is, to raise use-efficiency of parking place and to help drivers to select easily. When we manage the parking place m the block efficiently, It can prevent disproportion that some parking space is over capacity and the other parking one is under. It causes not only the disproportion of economic efficiency but also the congestion of local road. The precondition to manage parking efficiently is to analyse the parking characteristics. In this study we found out the characteristics of parking vehicles by analyzing the turnover per parking mesh and occupancy rate And we build up total D/B by collecting every information about parking space. We developed the Parking Management System by using GIS with D/B and digital map. The efficient Parking Management System is for convenience of drivers and efficient usage of parking space. And this system is also the basic study to be developed as the total Parking Management System by upgrading every information.
