Abstract
One of the promising areas of improving the constructive and technological solutions of low-rise buildings is the fast-erecting systems. Increase of efficiency of the erection process of these systems can be implemented on the basis of the results of a multiple-criteria analysis of the organizational and technological processes by decomposing it into separate technological processes and operations and assessing their impact on the overall building erection process. The structure of a multiple-criteria model includes such indexes as the duration of separate technological processes and the operation of the overground part in the building erection. The subject of the study – technological operation parameters during the installation process of the transformable low-rise buildings with sandwich panel walls. Based on selection, classification, and systematization of the factors determining the resultant indicators, the relationship between the effective indicator (function) and the factors (arguments) was studied and their forms of dependence were determined based on the linkage modeling. The calculation of the influence of various factors and their assessment on the change in value of the effective indicator was performed. The selected factors include several parameters in the form of technological operations, which are expressed in hours. The simulation of technological process using a multiple-criteria model allows determining the efficiency reserves of the developed technology. Its application in installation control processes could help the construction industry with transformable low-rise building erection.
Highlights
The development of low-rise housing construction is an actual task related to ensuring the comfort of various social layers of the population
Its solution is in the plane of balanced interests of all participants of the investment and construction process and consumers of construction products
The fast-erecting construction technology means a significant reduction of labor costs at the construction site in comparison with the factory works
Summary
The development of low-rise housing construction is an actual task related to ensuring the comfort of various social layers of the population. Modern low-rise building construction technologies are developing in the direction of construction time reducing. The ratio between labor costs in the factory and at the construction site is changing toward to installation works reduction during the process of building erection. The fast-erecting construction technology means a significant reduction of labor costs at the construction site in comparison with the factory works. For construction effective form organization of alternative structural and technological systems, it is necessary to have an information about the composition and structure of construction process technological parameters. The technological parameters of low-rise building erection are significantly different in dependence of the chosen design and technological solution
