Research On The Relationship Between Safety Input And Performance In Construction Enterprises

As a high-risk industry, construction enterprises should not only plan for the economic development, but also have a "safe development" strategy. Under the guidance of basic principles "safety first, prevention first", the majority of Chinese construction enterprises have adopted some policies and measures in all links of construction projects, and have invested certain manpower, material and financial resources in security management, but the effect of the input is not obvious. According to the current phenomenon that construction companies have not implement a reasonable investment and is not willing to invest, contrary to the objective laws in pursuit of benefit and rate, seek safety in the fluke, and also considering the problems such as the quantitative of safety performance in construction enterprises, this paper focused on the study of the relationship between safety input and performance in construction enterprises. Main contents of this article are as follows:(1)The security situation of construction industry in China, domestic and foreign construction safety management status are described in detail, all of the casualty situations in nationwide building operations are analysed in depth. It comes to a conclusion that the types of the casualty of building operations are mainly "Five Hurt":falling from high places,landslide, attacking by falling objects, electric shock, injury by lifting.(2)The implication, classification and source of the safety input are introduced in detail, security investment decision-making game models of construction enterprises is built and the Nash equilibrium solution is obtained.At the same time, the safety input of construction enterprises is calculated and optimized.(3)The relationship between features of engineering project and safety performance is studied, it provides a basis for the security related management measures that taken to the people affecting production safety of engineering project. The necessity of quantifying the safety performance of construction enterprises is analysed and the paper also proposes that safety performance is quantified to achieve safety benefit.(4)Taking the item of shan yang hiend comprehensive office building for example, using the evaluation methods of safety performance introduced last part, the author has set up safety performance evaluation system for this item.(5)The author makes a study of the ralationship between security input, benefit and the level of safety, then assesses the benefit of the investment for safety in detail, analyzes the main indication and the relation between the input and the benefit for the security, meanwhile, conforms the way and area of improving safety benefit.
