Flow-line production method in the residential construction: analysis of the state, problems and development trends

Methods in the modern residential construction must meet the requirements for the effective use of material and labor resources. Today, three methods are used in construction: successive, parallel, and flow-line methods. The most progressive and providing a rhythmic output of construction products and an even use of resources is the flow-line method. The article considers the use of the flow-line method of the residential construction both in high-rise multistorey construction and in low-rise construction of suburban settlements (micro-districts). In the work, we analyze the problems and prospects of using the flow-line method of construction in the Irkutsk Region. We discuss main advantages and disadvantages of the most common technological and constructive solutions of the flow-line method in the residential construction. The paper analyzes possible combinations of methods in the residential construction. It has been found that when using the parallel-flow method, the duration of construction is reduced by an average of 20%, and labor productivity increases by about 10%. The economic efficiency of the flow-line (parallel-flow) method is manifested in the reduction of construction time, reduction of downtime of resources and (or) individual spreads of work, increasing labor productivity and the profitability of the residential construction.
