This article is dedicated to the study of the structural characteristics of the twostorey caravanserai building of Mashadi Shukur Mirsiyab oglu, a historical architectural monument dating back to the late 19th century, located in the central part of the city of Shusha. The structural scheme of the building has been identified, its structural drawings have been restored, the actual strength of the construction materials used has been determined, damages in the structural elements, foundation, walls, ceilings, and domes have been identified and classified by their level of risk. The technical condition of the building has been assessed, and proposals and recommendations for its restoration have been developed. 

To reduce the wave effect on the structure, eliminate the formation of reflected waves with their dangerous eroding effect, accumulation of sediments in the wave space and reduce the cost of the structure, underwater breakwaters are being built. The basic information about the structures of underwater breakwaters, the basics of their design and calculation are given. A systematic analysis of modern innovative technical solutions in the field of design and engineering of underwater breakwaters is presented 

The article analyzes the main features of construction in Azerbaijan during the 1920-1980, the general architectural and urban planning features of construction works. It is substantiated that they do not fully meet modern requirements, and although they partially meet the requirements of durability and strength, they are more subject to moral erosion. Against the background of the high achievements of construction in our country, the shortcomings of 5-story buildings are more noticeable (both in terms of operation and planning), for this purpose the possibility of their reconstruction and planning has been analysed. 

In this article, referring to the standards for concrete fillers, it is shown that when determining the frost resistance grade of the same material both by the freeze-thaw method and by the accelerated hardening method, the same results are obtained. However, studies have shown that the frost resistance indicators of fillers for concrete made of intrusive, sedimentary and metamorphic rocks when determined by both methods provided for by the standard and when assessed give the same result for grade F100. Determining the frost resistance grade of fillers from effusive rocks by both methods gives different results. When obtaining the frost resistance grade F100 by the freeze-thaw method for a filler made of effusive rocks, the accelerated method yields the frost resistance grade F50. It is shown that this discrepancy may be due to the presence of glass phase and amorphous silicon tetroxide in fillers from effusive rocks. 

Экологическое проектирование представляет собой систему проектных решений, обеспечивающих минимальное воздействие на природу, рациональное использование ресурсов и создание благоприятной среды обитания. В статье дана оценка принципов и перспектив экологического проектирования. В статье проведен обзор ключевых принципов, задач и направлений развития экологического проектирования. Подчёркивается  значение  внедрения  «зелёных  стандартов»  (LEED,  BREEAM,  DGNB и др.) как инструмента минимизации воздействия зданий на окружающую среду и повышения  энергоэффективности. Рассмотрена   международная практика сертификации зданий.

Along with other architectural monuments, the caravanserais built in the 16th century were of great importance in Anatolia region, which became an important crossing point of trade route from China to Europe. Those caravanserais reflecting different styles of Ottoman architecture were built on or near the main crossing point of the Great Silk Road. One can show such examples including Kurshunlu (Istanbul), Rustem Pasha caravanserai (Edirne), Sokullu Mehmet Pasha caravanserai (Luleburgaz), Chelebi Sultan Mehmet (Kutahya), Shahzade caravanserai (Manisa), Shepherd Mustafa Pasha caravanserai (Izmit), Sinan Pasha caravanserai from Sinjan (Afyon), Rustem Pasha caravanserai (Konya), Sultan Selim II caravanserai (Konya) and others. In the article the study carried out on the architectural features of several caravanserai samples gives information about the general features and architectur 

The article discusses the sustainable development of Baku, urban planning and the ecological aspects of buildings. It presents information on environmental assessment, with solutions in line with the principles of strategic planning and sustainable development..
