Sequence of implementation of work during reconstruction with buildup of the mansard

Abstract

In the article described the basic principles of the organization of work for the mansard floor in residential buildings, the sequence of work, the definition of labor costs and the design of the calendar plan. The most economical, simple and effective technical solution for the reconstruction of buildings of any structural systems is the superstructure of mansard floors. The sequence of organization and planning of works during the reconstruction of buildings with a mansard superstructure includes: establishment of nomenclature and counting of works; choice of methods of organization of production of works; calculation of labor costs of workers and the need for rotation of machine; determination of the duration of the reconstruction works; creation of a calendar plan and schedule of work. The main work cycles for a mansard floor superstructure should include: preparatory work; dismantling works; reinforcement of existing structures (foundations, piers and attic flooring), if necessary; arrangement of a monolithic ring beam for rigidity providing; erection of mansard floor structures (walls, roof, partitions, window and door fills); arrangement of engineering systems (mansard); decoration (internal and external); commissioning of the object. The choice of methods of organization of production of works is carried out in parallel with the definition of the nomenclature and the calculation of the volume of works. It is known that the operating method combines sequential and parallel one, it eliminates the disadvantages and retains the advantages of each. After determining the nomenclature and choosing the method of reconstruction, we calculate the of labor consuming. The next stage is the designing of the calendar plan of reconstruction . When designing a calendar plan of reconstruction, it is necessary to ensure maximum time alignment of technological processes and their continuity, taking into account the requirements of job security.
