Methodology for substantiating the need for construction machines and mechanisms in the development of construction organization projects
Abstract
The article proposes to determine the number of construction machines and vehicles when developing construction organization projects, taking into account the output of equipment for maintenance (maintenance) and repair. To do this, it is provided for the estimated period of use in the construction of each machine to set the dynamics of changes in the probability of its working condition over time and coordinate the schedule of construction work with the schedule of maintenance and repair of machines. For Liebherr L556 single-bucket front loaders, the dependences of the failure rate parameter on operating time, as well as the probability of failures between two adjacent maintenance units in the conditions of failure elimination by maintenance services, have been established. The results obtained can be used to justify the number of workable machines and means of transport in construction projects.
