Construction Quality And Risk Control Of A Girder Brider Engineering Change

With the development of economy and society, continue to improve the railway system, railway construction has been developing by leaps and bounds, China’s railway construction mainly high-speed railway construction, railway construction and our daily lives, it’s construction guarantee our security in favor of convenient transportation. Today, the rapid development of railway construction also continued emergence of a lot of quality, a lot of railway construction unit for their own interests, continue to shorten the construction period, so to speed up the progress of the project, which would make a serious decline in the quality of the project, Finally, the project will lead to unqualified acceptance that some unsafe casualties often occur, this will cause railway subsequent quality issues abound. Construction and Management is a diversified engineering program, a lot of internal factors will lead to a qualitative change in the whole process. A construction management goal is to work in a reasonable period specified, to play its cost-effectiveness, quality assurance and construction safety, to maintain normal smooth construction project. It requires the contracting company to ensure its development, provide competitive capacity and to ensure construction quality and safety. Only by strengthening the construction quality of engineering science management and risk prevention, we can achieve the fundamental purpose of the construction of meaning construction is completed, in order to obtain higher returns.Based on the construction of a bridge beam as an example, expounds the engineering project quality control and method of risk assessment, and combined with some of the railway construction project risk factors affect the quality of the comprehensive analysis. Quality control on the basis of the above analysis is divided into the owner, the construction unit, supervision unit and other survey and design quality control. Then use analytic hierarchy to project construction risk evaluation for eight; Finally put forward the construction quality control plan, such as the assurance of pair of drawings and the construction process of the overall management, improve and comply with construction norms, reasonable division of labor responsibility is difficult to implement, etc.; For the technical problems such as wet strengthening construction and blockade and slow, formulated the detailed quality control plan, to ensure the engineering quality.
