Assessment of Organizational and Technological Reliability of the Construction Process

Abstract

The article proposes the solution of the topical issues that arise in the construction of buildings and structures, among them are: ensuring high reliability in calculating the duration of work in construction projects, determining the minimum boundary of the actual intensity of work in the construction of building structures. Objective: to offer a simple option for assessing the value of the reliability of the construction process. Within the framework of the research, the following tasks were solved: the typification of construction processes according to the degree of mechanization was carried out, a simple method of probability theory was proposed to determine the reliability value. Methods of forming the general set of initial values ​​suggest using observation and timing. Processing of statistical values ​​was performed on the model of the accumulated probability curve. As a result of the research, the construction processes are considered as fully mechanized, non-mechanized (manual) and processes in which the machines and workers are jointly occupied. A practical example of obtaining the values ​​of productivity from a given value of reliability on the curve of accumulated probabilities is given. The conclusion is made about the advantages of the described approach, which consist in the simplicity and low laboriousness of constructing a model, as well as performing calculations.
