Abstract. The method for determining the duration of a combined foundation device, which is constructed in several stages, is considered in the article. The main stages include the construction of structures and the regulation of the stress-strain state of the soil base, which is carried out by pressing it. Pressurization is carried out during the construction of the building. On an example of construction of the linear schedule the mutual coordination of works of each stage during building of a building is resulted. The possibility of varying the time parameters of the network model is presented depending on the parameters of the crimping process. Between the late and early beginnings of work there is a common time reserve, which is part of the technological break.

The authors present empirical data on the actual duration of concreting of grillage of combined foundations. The study of time parameters of technological processes was based on such methods of observation as timekeeping, photo-timing and video and photo-fixation. The measurements were carried out during the construction of the residential complex «Neighbors» in Tyumen. The scope of research included the study of labor costs of the team, consisting of seven concrete workers. The investigated technological process of concreting consistently included the reception and direction of the concrete mix, laying, leveling and compacting the mixture, smoothing and smoothing the grillage surface.

Based on the data obtained, the dependencies of the average duration of concrete work on the volume of the concrete mix laid in the cells (shells) are revealed. The comparison of work durations on both foundations is made. Actual work is determined and work time standards are established, allowing to organize concrete works with sufficient precision when drawing up calendar plans within the framework of working out of projects for the production of works.

This article is made in the framework of the dissertation research by co-author Volosiuk D.V.
