1.4. Artistic and aesthetic solution

The exterior of a multi-storey residential building is closely related to its internal layout, structures, materials and construction methods. The decisive influence on the appearance is made by multi-family, a combination in one volume of a large number of repeated apartments. This combination creates a kind of mesh construction of the facade .

In this five-story house, the details of the facade - the grouping of windows of various sizes, balconies of loggia, elements of decoration determine the rhythmic construction of the facade, betraying the house with a characteristic appearance.

The solution for the exterior decoration of the building: granite, dolomite, ceramic brick, plaster, natural stone - is provided taking into account the color and textures of the existing development of the microdistrict, in order to create a favorable coloristic climate and give sharpness to the composition.

1.5. Architectural and structural solutions.

When designing the structure, the reliability factor is adopted.

The structural diagram of the house is a system of mutually perpendicular brick walls. Floor support is made in longitudinal direction. To ensure spatial rigidity of the building and reduce deformations, the project developed a set of measures aimed at engineering preparation of the base and increasing the rigidity of the building. Prefabricated reinforced concrete items are accepted according to TK201 catalog. 5984. Base preparation is made by layer of crushed stone (50 mm). The foundations are designed monolithic, reinforced concrete, in the form of cross belts of heavy concrete in 15 on Portland cement according to GOST 1017876 with mineral additives with coating waterproofing with bitumen in 2 passes. The basement walls are made of prefabricated concrete blocks according to GOST 1357978, an antiseismic monolithic reinforced concrete belt 500 mm thick is made on the basement walls under the floor. cross-section not less than 150 by 220 mm, concrete grade not less than 150. Antiseismic belts shall have longitudinal reinforcement of 4 10 mm. (7... 8b) from Class AIII fittings).

During the construction of the underground part of the building, the following measures are provided: organization of cavities for the commissioning of communications and the organization of a heat station.

3. Job Instructions

Routing is a project document that defines the technology, organization and economic indicators of an individual construction process.

This project provides for the development of two Job Instructions: for the construction of monolithic foundations and the installation of floor slabs.

The initial documents for the development of Job Instructions are: detailed drawings of this project, building codes and regulations (SNiPs), instructions, standards and technical specifications for installation, ENiRs for construction and construction.

Schedules of construction and installation works are developed for these task lists in the form of calendar plans, which are a graphic representation of the development of construction processes over time.

Installation of the load-lifting C981A tower crane SMR should be made for performance according to stroygenplany the present project. Before commissioning of the tower crane, drawings of the organization of its safe operation must be presented to the inspector of Gostekhnadzor.

4. Work schedule (shift).

The calendar plan is designed to determine the sequence and timing of civil works, special and installation works carried out during the construction of a residential building.

These parameters are established as a result of a rational linkage of the deadlines for certain types of work, accounting for the composition and quantity of core resources, primarily working teams and leading mechanisms.

According to the calendar plan, the need for labor and material resources is calculated in time. On the basis of the CP, the progress of work is monitored and the work of the performers is coordinated.

The initial data for the KP are: civil, estimated part of the project, as well as the bill of quantities of work, calculations of necessary resources, description of the construction and construction methods, survey documentation, including data characterizing the capabilities of the contracting organization, standard terms of construction of the designed object, construction of a residential building.

Previously, the duration of the construction of the designed 5-storey residential building is determined by the enlarged indicators according to SNiP 1.04.0385 * "Standards for the duration of construction and backlog in the construction of enterprises, buildings and structures."

The planning schedule for the complex execution of the construction of the building (or separate units) is developed based on the condition of uninterrupted two (three) replacement work of the crane with a complex team of workers at an 8-hour working day.

The basis for the planning schedule is the list of labor costs and working time of the machines, the chosen method of work execution, the number of grips, the sequence of work execution.

Installation works, formwork arrangement, grouting of individual units and joints between prefabricated reinforced concrete products, welding works, works on installation and disassembly of scaffolding are linked on the schedule schedule. The designed composition of the links is accepted in accordance with the indication of the TD.

The terms of work execution are determined by dividing the projected labor costs by the number of workers in the link performing this work.

To determine the total number of workers per shift or day, you should make sections on the graph on the days when individual work begins or ends.

The obtained data are shown at the accepted scale in the graph "number of workers - duration."
