An approach is proposed to determine the preference of a construction object in planning the order of construction of objects of a production program of a construction organization. Priority is given to objects that have priorities over others, in this case, we can talk about the application of the priority rule, by means of which the order of construction is ordered. Each building object has a number of features, from which one can be judged its preference over other objects. Many preference signs seem like a matrix in which the column is a class, the string is a subclass of attributes. The feature class reflects the aggregate properties of the object, the subclass is the distinguishing characteristics of the characteristic within the class. A set of attributes on one of each class constitute a priority group. Priority groups are ranked to order their list. The proposed methodology was tested with the involvement of expert students who complete their studies at the University. Priority of construction of cottages of three kinds was determined. The results of the research formed the basis for recommendations to construction organizations that conduct individual housing construction.

High cost and shortage of cement in the construction market of the Russian Federation determines the need to find ways to save it. One of the promising directions of improving the technology of concrete, providing the opportunity for significant savings of cement is the production of concretes of new generation. Such concretes are of high quality or highly functional. Mandatory element of the technology of such concretes is the introduction in their composition of organic additives (OMD). Using the methods of the experiment planning theory in the developed compositions of organic additives depending on the fineness of the mineral component and dosage of superplasticizer. It is established that the use of the proposed organic-mineral additives will allow to save from 15 to 30% of cement without loss of concrete strength.

The problem of parking of cars on the street-road network of the city of Volgograd is considered. The methods of parking at different angles in the winter season have been studied, and the most optimal one has been selected and justified. Dense building does not allow to solve this problem by searching for other parking places, since each driver has a desire to be within walking distance of the car to the object he needs. In residential areas of the city with the existing buildings, this problem is difficult to solve, therefore, it is necessary to improve the existing schemes for parking in the instrument areas

The problem of determining the environmental hazard in the development and disposal of oil contaminated soil at the time of construction of buildings and structures is very relevant, especially for sites on which previously located industrial zones with different production. Unfortunately, at the moment, there is no clear understanding of the MPC of petroleum products in the ground. Various inspection inspections and specialized landfills treat the degree of soil contamination with oil products in different ways. In this regard, there is a danger of incorrect definition of the hazard class of the soil, which can lead to subsequent pollution of the environment.
