Introduction

The city of Novosibirsk is currently being intensively built up, both on the outskirts of the city and in its central parts. For the most part, this is due to the need to expand residential real estate, but commercial real estate also does not play a small role in this market. A lot of real estate is now given to shopping centers, specialized stores, entertainment complexes, restaurants, and everything that can bring income to all kinds of entrepreneurs and companies. And they, in turn, need offices where they can competently carry out their business.

There are many office buildings and business centers in Novosibirsk, but there are more and more people who want to purchase them near the center, and this desire is justified. Therefore, it is important to maximize the use of the central space of the city.

Therefore, today, along with new construction, it is necessary to pay attention to the completion of the construction of abandoned buildings and the reconstruction of many buildings, for example, the expansion of the areas of buildings, additions and superstructures of floors .

When developing the project for the reconstruction of the building, in the form of a superstructure of two floors, including attic, data on the results of the survey were taken into account, which described changes in regulatory documentation, the presence of defects and damage caused by poor-quality installation.

The optimality of the reconstruction of old buildings with the simultaneous superstructure of an additional floor and attic is not in great doubt: quite comfortable living areas appear, due to their sale, existing areas are overhauled and strengthened. This direction seems promising and effective enough for further development and implementation.

All these issues are considered in the diploma project, and conclusions are given on the results of the calculation.

Master Plan

The reconstructed office building is located at 33/4 Tolmachevskoye Shosse in the Leninsky district of Novosibirsk.

The general plan of the reconstructed building has been solved taking into account the surrounding buildings, existing engineering communications and transport links.

The relief of the site is calm, without sharp height differences.

The main facade of the building is oriented northeast.

The project provides for the improvement of the area around the building. From the side of Arkhonsky Lane, a parking lot for passenger vehicles is organized .

The pavement of driveways and sidewalks is designed from asphalt concrete.

Drainage is provided for asphalt concrete pavement of projected passages with subsequent discharge of storm and meltwater into the city storm sewage network.

In the landscaping system, the arrangement of lawns and flower beds, as well as the planting of trees and shrubs along the perimeter of the territory, is accepted.
