Abstract. One of the most important tasks of Russia's Ministry ofConstruction is the compilation of the registry of building designs approved for repeat use in public facilities construction. When completed, this registry will facilitate the design process and reduce building-related costs and construction timeframes. The existing guidelines, standards and regulations applicable to repeat designs are analyzed. Challenges hampering the broader use of repeat designs are assessed and possible solutions are suggested. The article presents a set of criteria for the selection of the most efficient designs recommended for repeat use (technical and technological evaluation, investment attractiveness, operation and maintenance costs estimate).

Every year the number of free land plots for construction of buildings is steadily decreasing in cities. In this regard, the participants in the investment and construction process are increasingly seeking to maximize the use of land. A logical way for this is to use high-rise construction. However, until recently, builders encountered serious obstacles in the form of lack of special norms and rules for the design of high-rise buildings. It led to the need for individual coordination of each high-rise facility, the development and approval of special technical conditions, the passage of numerous administrative approvals. Thus, investment activity regarding the construction of high-rise buildings in the Russian Federation is reduced. In 2016, there were regulatory changes that substantially alleviated these difficulties. In this article, the authors analyze the features of the town-planning normative-legal field of high-rise construction and its development, track the interrelations between the regulatory regulation of the construction of similar facilities, with the real need, the technical feasibility and economic feasibility of their construction in the urban district of Samara. Conclusions and suggestions are also based on the analysis of the norms of urban zoning, the residential real estate market and the value of land plots.

The value of a land plot or property rights to it is an important link in the investment and construction design. This paper considers a transparent, comprehensible and justified mechanism for the development of cost parameters using a case study of land plots provided for construction located on the territory of the Stavropolsky municipal district of Samara Region. The obtained cost indicators of the land use provided for construction are determined based on the analysis and examination of not only real lease agreements but also using alternative calculations. While calculating the indicators, the authors applied the principles taken from the Decree of the Government of the Russian Federation of July 16, 2009 No. 582 as well as the analysis of real land lease contracts for construction and calculations based on current standards and the development of construction costs based on aggregated indicators.

The paper presents an analytical method of modular buildings calculation. It focuses upon basic design assumptions that are accepted for modular buildings calculation. The authors introduce their classification of loads and impacts, which are basic for modular buildings. They also describe a method of determining inertial forces from seismic action designed on the basis of a cantilever analytical model. Analytical and numerical methods for determining the forces in the elements of modular units are further compared. It is revealed that the analytical method strongly agrees with FEM (that is the finite elements method) with the error being 2-6%. The analytical method is sufficiently accurate for engineering calculations.
