Design organization and construction implementation of the installation and reconstruction technology using helicopters

Abstract

The article analyzes the helicopters’ rational flight operation issue state in the reconstruction projects’ design and implementation to replace the cover structures of single-story industrial buildings. The practical use experience of helicopters in the conditions of an existing industrial enterprise is summarized. The basic prerequisites for the use of helicopters for the structures’ dismantling and installation are described. The joint development issues of the reconstruction projects using helicopters are considered, taking into account technological and organizational aspects. The structure and relationship of the technological process organization individual elements. A scheme for organizing and implementing a rational technology for mounting and dismounting using a helicopter, professionally trained flight crews, teams of ground installers to perform mounting and dismantling work during the industrial facilities reconstruction has been developed. The possible ways of expanding the operational range when using helicopters for installation and dismantling work are shown.

Simulation Modeling of Aerial Work Completed by Helicopters in the Construction Industry Focused on Weather Conditions

“…The basic idea of simulation modeling in the preparation of buildings is to replicate as closely as possible the situation at the intended real construction site. The importance of this step is emphasized by Balakchina and Shalenny [8], who stated that the number of flight hours and the price per flight hour of a helicopter are often the main factors influencing the cost of the process; therefore, it is appropriate to verify the proposed process by simulation and choose the most advantageous among the different variants. Thus, when setting up the simulation model for helicopter work, other specific issues that must be addressed for the use of a helicopter at a construction site have emerged and are the subject of discussion:…”

“…Airline operators will obtain an automated system that will save time compared to manual processing and will allow the ability to verify alternative scenarios in the event of operational delays due to adverse weather, which, in practice, occurs very often. Balakchina and Shalenny [8] noted that the achievement of efficiency in aerial work using a helicopter directly depends on the ability of the construction contractor to take into account the characteristics of the helicopter and the overall quality level of construction technology preparation, with regard to the technological and organizational regularities of such work. We share this view.…”

“…Aerial work in which helicopters are used is also proving its benefits in areas with less or no nature protection, such as the densely built-up inner zones of large cities. They are also used in the reconstruction of existing buildings [8]. As a result of the above side effects, construction work carried out by helicopters can be cheaper than it would be with conventional ground technology, and its time duration can be shorter.…”

“…Therefore, we can also talk about economic sustainability-characteristic for aerial work that it is carried out in a three-dimensional space (the atmosphere), which is strongly influenced by the current weather conditions primarily [9]. Thus, the very nature of aerial work naturally implies that its preparation is more demanding compared to that of conventional technologies [8]. Therefore, it is necessary to choose such means and methods that will help to ensure (to some extent) not only the obvious environmental sustainability, but also the real economic and practical benefits of this technology, and thus, ultimately, the legitimacy of its existence and the long-term sustainability of this method of construction.…”

“…A suitable tool for determining the optimal variant is simulation modeling, which adequately represents the authenticity of variable conditions in real-world construction practice. Balakchina and Shalenny [8], in their work, pointed out the need to verify various variants of technological procedures in aerial work using simulation modeling.…”
