Preparation of the territory for construction on the basis of photogrammetric information and information modeling To reduce material and time spendings during surveying and pre-plan study there are advanced features of data collection and its handling. The paper considers creation of digital relief model (DRM) and information modeling based on photogrammetry data. During the work, an aerial survey was carried out from an unmanned aerial vehicle (UAV). Based on the photogrammetric survey results, a 3D terrain model was developed and a sketch model of the territory arrangement was created. 3D terrain model and data processing realized with using of Autodesk ReCap, Autodesk Civil 3d and Revit. The experience of photogrammetry data using gives an oppertunity to estimate it like a highly effective and low labour cost in comparison with traditional surveiyng methods 10.34910/ALF.8.1 digital elevation model photogrammetry 3d surface model and terrain objects digital relief model aerial surve https://alfabuild.spbstu.ru/article/2019.8.1/ 8_1.pdf

First floors thermal insulation with slag wool The main problem with the use and matching of different kinds of slag wool as a floor insulation for the first floors is its ability to practically full lose its heat insulating properties in the soaking. After that, the material becomes in absolutely unsuitability during several seasons. It ceases to retain the heat and requires immediate replacement. This problem leads to an instant decline in the quality of life, so adherence to special requirements is an important practical task. The purpose of this article is conduction a detailed review of slag wool as a floor insulation for the first floors, including its classification by the type and the form of release, consideration of the most significant advantages and disadvantages of its various types for generalization and formation of both practical recommendations for eliminating the drawbacks of this material and the optimal technology of insulation of the first floors with slag wool. The main advantages and disadvantages of using slag wool have been revealed by the method of information analysis. Practical recommendations for minimizing the impact of negative factors of this material on human during matching and direct use as a thermal insulation have been given. Step by step optimal technology of the first floors insulation with slag wool based on studying the material features have been formed and described 10.34910/ALF.8.2 69 Civil engineering construction buildings energy efficiency slag wool thermal insulation thermal-insulating materials heat insulation https://alfabuild.spbstu.ru/article/2019.8.2/ 8_2.pdf

The concept of a footbridge, that leading to the Lakhta Center Lakhta Center is a grandiose project of modernity. People used the most advanced materials and equipment to create it. Construction will be completed at 2018. Huge streams of people want to look at the modern creation of St. Petersburg. Unfortunately, Primorsky region is not able to withstand such a huge stream of tourists and residents of the city. At the moment, the pedestrian accessibility of the Lahta Center is extremely small. One way to solve this problem is to ensure the accessibility of the Lakhta Center by a pedestrian bridge, that leading from the 300th anniversary park of St. Petersburg. At the same time, model of bridge is in modern architectural design and contains all the requirements of bridge construction. The work consists of sections, including the analysis of existing projects, the analysis of pedestrian accessibility, the creation of the concept of a pedestrian bridge of the present, an opinion survey of the Primorsky region residents, functional and distinctive features of the bridge 10.34910/ALF.8.3 69 Creation of the project Providing pedestrian accessibility Analysis of pedestrian bridges concept of the future bridge modern image of the bridge Availability of Lakhta Center https://alfabuild.spbstu.ru/article/2019.8.3/ 8_3.pdf

Frame-panel housing construction of Canadian technology The choice of material for walls is the main problem for erection of a building. Structural Insulated Panels (SIP) gain popularity for the construction of low-rise buildings. The purpose of the study was to research of advantages, disadvantages of this material and its prospects of development in the building market. The purpose of this article is identification of the prospects for using the material in low-rise housing construction. The article is based on brief overview of the scientific publications. The study showed that panels have good technical and economic characteristics and high level of heat protection. Based on the findings was established that Buildings made of Structural Insulated Panels allow to solve the problems of comfortable and affordable construction. Nowadays CIP-panels is becoming increasingly popular for the construction of houses on the countryside 10.34910/ALF.8.4 residential construction; structural insulated panels; construction market; energy conservation; building materials; low-rise buildings; durability; construction method https://alfabuild.spbstu.ru/article/2019.8.4/ 8_4.pdf

Varieties of materials for disperse reinforcement of concrete In this article different types of disperse reinforcement are considered including steel and polypropylene fiber, carbon fiber and carbon nanotubes, basalt and glass fiber, which are used for the production of fiber reinforced concrete and high performance concrete. The advantages, disadvantages and possible difficulties of using each of the types of fibers are described as well as ways to prevent these problems. In addition, several ways of preparing fiber-reinforced concrete, namely the introduction of fiber into the concrete mixture, are given in this article. Conclusions are drawn about what is important to take into account while choosing fiber, how to avoid problems arising when using reinforcing fibers and which type of fiber are preferable for high performance concrete. The comparative characteristics of strength, modulus of elasticity, relative elongation and density of materials used for the production of fibers are given 10.34910/ALF.8.5 disperse reinforcement fiber fiber reinforced concrete high-performance concrete construction https://alfabuild.spbstu.ru/article/2019.8.5/ 8_5.pdf
