Variability of work overlap during capital repair of buildings

Abstract

Introduction. Capital repair of buildings is a comprehensive process that encompasses a wide range of building maintenance and construction processes. To achieve maximum efficiency, it is crucial to properly plan and manage resources, taking into account the specifics of objects, conditions, and characteristics of work performed. It is necessary to study and implement methods for combining operations that allow reducing the duration of capital repairs and lowering costs in construction and maintenance production.

Materials and methods. In this research, modern approaches to designing organizational and technological models for capital repair production were utilized. Algorithms for calculating parameters such as resource consumption intensity, task execution duration, and interprocess connection conditions were developed. Special attention was given to methodologies for assessing organizational downtimes and modules enabling efficient distribution of labour and material resources.

Results. The proposed methodologies enable optimization of capital repair processes through rational allocation of resources and overlapping of works. The use of combined flows for roofing, facade renovation, and engineering systems installation in multi-apartment residential buildings demonstrated significant reduction in total repair time without compromising the quality of executed works. Developed algorithms provide computational justification for selecting an optimal method of performing tasks.

Conclusions. The conducted research confirmed the significance of variability in overlapping works during the capital repair of buildings. Proposed algorithms and techniques make it possible to significantly reduce both the time required for completion and the cost of the works.
