The article touches on transforming and changing architectural and spatial environment of the city. Three main approaches to the reconstruction of historically valuable areas are identifi ed. A detailed analysis of the historical area in Samara is presented and a proposal of zoning area for a social business center is given.

This article analyzes the artistically-shaped qualities of cable-stayed bridges, their place and role in the structure of the conception of the city. The article describes the different forms of expression of these qualities in changing situations of the city environment. The problem of the functioning of the cable-stayed bridges in the structure of the city image does not become an object of special studies earlier. Studying the cable-stayed bridges from a totally different point of view is the novelty of this article. Researches in the bridge building assume special importance in sight of the increase of the cable-stayed bridges number built in Russia, and in sight of the optimization of this type construction.

The modern state of the concept of continuity in the context of urban development and transformation of a fundamental element of the major historical cities - planning structure of the city. Emphasizes the relevance of understanding the continuity of urban planning as a fundamental property of the planning structure of the city. Raises the issue of the need to develop a common methodology for the study of successive development of the planning structure of the city.

The article considers the current legal documents in order to eliminate the pre-school organizations, adopted at the federal and regional levels. The analysis of the applicability of each event in the urban environment of Samara is made. The dependence of the change in space-planning and functional structure of the building preschool organization of the introduction of new legal regulations is defined. Denotes the possibility of an integrated approach to addressing the problem of pre-school education.

The common procedure of definition of functioning reliability of water supply and wastewater systems is proposed. This procedure contains three stages. At the first stage the time of being in working and improper states is defined by using apparatus of queueing theory. At the second stage operable and unoperable states of improper states are determined with engineering simulation methods. At the third stage the work time of an object and the time of its being in critical and failed conditions are defi ned. This procedure is demonstrated by the example of 2-nd lift pump station.

Information about the main directions of wastewater systems renovation in the Republic of Armenia is presented. The apparatus for receiving of surface flow in sewage system is proposed. This mechanism provides an opportunity to roll back the following monitored indexes: organic material concentration, dissolved oxygen, oxidationreduction potential, oxygen uptake rate by active sludge. The research points at adequate security of biomass by oxygen in the process of aeration and at practicability of use of ceramic aerators from armenian tuff for the first stage of wastewater systems renovation.

The article shows the problems of vegetal invasion and pollution of small rivers. The methods and used equipment for cleaning of water in different periods of the development of society are described. There are recommendations and information of using dredgers in Samara Region.

There are given results of engineering inspectation of metal outdoor units of petrochemical industry enterprise. The main causes of damages, their consequences and impact on the environment are shown. Replacement of damaged structures in the conditions of operating production with unloading overlap by posting of existing apparatus to the overlying structures intact constructs is offered. Preference is given to protection of metal structures of special swelling compositions.

Calculation methods and exploratory tests of dead air space heat-shield performance are viewed. Construction solutions of slabs, coverings, outside walls heat-insulated with screen heat insulation are proposed.
