For advanced construction safety, it is able to valanced control that are 'Enforcement', 'Engineering', 'Education'. It is central to an existing builders, that system problem about safety management is converted to a substantial and sensible system. Also, participates who are a governments, builders, designers, architects, supervisors with reference to construction project are developed labor saving technique for total system that is included planing, drawing, building, maintaining. And, it is to develop a program what is able to participate in an industry, a school, and an institute with governments that is for training professional for construction safety technique.

Float has been just recognized spare time for disposing of unexpected conditions as by-product of CPM(critical-path-method) calculations, in spite of important method for construction period, taking in material, human supply and cost reducation in construction process management. Also float necessary follow method of contract by ownership problem and effect construct management of use. The purpose of this study was to examine current recognition and application grade of float in construction project. In addition, the study proposes improvement strategies of float application for efficient progress plan and control.

Rework is a major cause that adversely affects the performance of a construction project, such as schedule delay or cost overrun. In order to prevent rework, research has been mainly conducted to analyze the cause of rework, but limited to quantitatively measure cost of rework and analyze its impact on project performance. Therefore, this paper aims to analyze impact of rework cost using 369 rework items collected from 3 construction site. This research is expected to accurately determine control target of rework and to improve efficiency of business operations in construction project.

The study seeks to cooperate with the investigation of a fire investigation based on public-private partnership. Fire protection systems provide a wide variety of viewpoints from the perspectives of design, construction, management, maintenance, maintenance and maintenance systems at a particular point in time, construction, management, and maintenance systems. What is controversial is that there are illegal activities such as illegal activities of the Patent Office, misconduct of construction work and unreasonable construction of construction works.As a theoretical framework, the present study identified the four key elements of a successful disaster response system : responsiveness, control, professionalism, and bias.

In order to conduct construction projects effectively, the work delay factors would be managed by planned construction schedules. As construction works are delayed ceaselessly, the solution is to select and manage the key factors which delay the work ceaselessly. The subjects of this study were an apartment houses of reinforced concrete structure. Hidden work delay factor were extracted, the surveys were conducted and occurrence, severity and detection of each factor were analyzed. With this result, final orders of priority were fixed and key management factors were deducted and presented.

The Development of Cost Management is embossed efficiently to use the budget for the construction industry. The government is exploring every efforts and polices to control increasing the budget for the construction industry. However, despite of the government's efforts, researches are insufficient for a cost management of development. Also, the changed cost of construction by frequent plan change is caused of decline in quality etc during an accomplishing project. Therefore, in this study, analyzed about principal official phase of design phase to solve the problem. In order to define clearly the target cost concepts in the planning phase apply to the DTC(Design To Cost) concept and technique at the development of cost management process which will be able to manage the enterprise expense. It's process is expected with the fact that will be the possibility efficiently of fixing target cost in the planning phase by the construction client and designer.

The modular construction method have improved quality, reduction of defects, such as the reduction of air, a number of advantages. It is utilized composite, larger, in skyscraper building already abroad. The domestic, various studies have been conducted on technical matters taller, automation of production, such as process control, but is still inadequate circumstances. Therefore, in this study, is the purpose that you have presented activation measures to investigate and analyze the case of co-housing with a modular construction system of outside, and to make the co-housing of modular construction system of domestic.

The domestic construction industry is becoming larger, high-rise and specialized. However, safety consciousness is still staying in low levels and falling accidents are apt to rise compared to other industries. So, the new way of safety management is required for reducing of the construction falling accidents. In this paper, we evaluate appropriateness of safety management on construction sites utilizing USN using smart safery equipment. Thus, we calculate loss costs of falling accidents considering accident rates and costs of the USN using smart safery equipment installation then compare both calculated costs. This research aims to propose the method for reduction of construction accidents in addition to conventional safety control methods by analyzing the propriety of applying USN using smart safery equipment on construction sites.

Change orders represent one of the largest sources of cost growth on construction projects, but an efficient change management control system can help the projects steer clear of the constant construction changes. This study was performed to achieve a better understanding of all changes and to develop a new set of Best Practices using process mapping techniques. The project data for this research were collected from case studies of aviation projects implemented in Houston, Texas at Bush Intercontinental Airport. The findings and contributions of this research should help owners and project managers determine and identify major causes that impact project budget and schedule and implement solutions prior to them surfacing.

The frequent maintenance required on some asphalt concrete (AC) pavement sections has made reconstruction with Portland Cement Concrete Pavement (PCCP) a feasible alternative. However, many constructability issues need to be addressed in order to realize the full potential of this alternative. Accelerated paving encompasses three classes of activities: methods to accelerate the rate of strength gain, methods to minimize the construction time, and traffic control strategies to minimize user delay. Three major AC intersections with severe rutting problems were reconstructed with PCCP. The entire reconstruction of each intersection, including demolition of the AC pavement and its replacement with PCCP, took place over a period of three days, starting on Thursday evening and opening the intersection to the traffic on Sunday afternoon. This paper discusses the use of PCCP for accelerated reconstruction of major urban intersections with minimal user and traffic disruption, using innovative construction techniques and traffic management optimization principles and demonstrates that concrete pavements can be constructed efficiently and quickly.
