Purpose. The article is aimed to create scientific tools based on the analysis of modern innovative approaches and tools to improve the processes of construction organization in the conditions of dense urban development using logistics, which has modern concepts of improving the corresponding processes. Methodology. A systematic analysis of scientific works in terms of problems of organization of construction processes taking into account the conditions of dense development, which serves as a platform for the introduction of innovative tools based on the field of logistics knowledge. Findings. The expediency of using logistical approaches and concepts is substantiated, taking into account external factors and limitations that are caused by the environment and configuration of the site, causing difficulties for the internal organization of construction. Logistics tools (approach) allow more efficient use of scientific and practical potential in the further development of methods for improving organizational and technological solutions of construction production under conditions of the functional and planning infrastructure of cities. Principles of logistics will allow to balance construction production in the conditions of dense building; to use flexible tools as an opportunity to make changes in the schedule of material purchase, changes in terms of delivery of building materials, designs, details; minimize stocks of building materials. Originality. Based on scientific research, a model of optimization of organizational construction processes is presented, taking into account the conditions of dense urban development and functional and planning infrastructure of cities. A qualitatively new specialized scientific and practical sub-branch of knowledge, construction logistics, was created for complex conditions of urban development to perform organizational and technological processes of new construction. Practical value. The use of logistics approaches will improve and optimize the processes of construction organization, taking into account the essential factors of functional and planning infrastructure of the city, in which it is necessary to make rational management decisions. Flexibility, alternativeness of production and economic situations and transport networks during the complex organizational and technological processes of construction make it possible to reduce the cost of construction and installation works and help reduce the duration of construction.

The second part of the translation has three segments. The first is dedicated to the history of Delhi from the time of the Mahabharat to the periods of Anangpal Tomar to the Mughal Emperor Humayun as also Sher Shah, the Afghan ruler. In the second and third segments Mirza Sangin Beg adroitly navigates between twin centres of power in the city. He writes about Qila Mubarak, or the Red Fort, and gives an account of the several buildings inside it and the cost of construction of the same. He ambles into the precincts and mentions the buildings constructed by Shahjahan and other rulers, associating them with some specific inmates of the fort and the functions performed within them. When the author takes a walk in the city of Shahjahanabad, he writes of numerous residents, habitations of rich, poor, and ordinary people, their mansions and localities, general and specialized bazars, the in different skills practised areas, places of worship and revelry, processions exemplifying popular culture and local traditions, and institutions that had a resonance in other cultures. The Berlin manuscript gives generous details of the officials of the English East India Company, both native and foreign, their professions, and work spaces. Mirza Sangin Beg addresses the issue of qaum most unselfconsciously and amorphously.

Design And Construction

With the increase of the population recently, changes have occurred in the design and construction techniques of the buildings due to the insufficient building stock. With the development of science and technology, new construction techniques have emerged in the construction and design of structures. In the global population increase, high-rise buildings were built to meet the need for shelter and these structures were built with the development of technology. However, high-rise buildings have become the symbol of technological development for countries and cities. Since the 21st century, the construction of high-rise buildings in cities with different designs and new construction techniques has provided the development of architecture and engineering. It is important to design high-rise buildings in accordance with the culture and texture of the city. In addition, high-rise buildings should be built as structures resistant to natural disasters such as earthquakes, fires and floods. For this reason, the design and construction techniques of high-rise buildings have become a research subject in the field of architecture and engineering. The aim of this study is to examine the designs and construction techniques of high-rise buildings. In the first part of the study, the concept of high rise building and its historical development are discussed. In the second part of the study, the designs and construction techniques of high-rise buildings are investigated. In addition, the study was conducted to examine the high structure by giving examples from the world and Turkey. Within the scope of the study, literature researches such as domestic and international articles, books, published theses, web resources were conducted and data were collected. As a result of the examinations made within the scope of the study, it is important to select the building materials in accordance with the characteristics of the building materials in the design and construction techniques of high-rise buildings with the development of technology. Therefore, the architect should know the properties of the materials in the design of high-rise buildings and use them in accordance with the properties of the material in the construction of the buildings. In addition, increasing the height of the building by making aerodynamic designs in high buildings reduces the effect of the wind speed.

In the process of urbanization of large cities in different countries, there are similar problems of reorganization, involving the demolition of physically and morally obsolete buildings and structures, as well as the subsequent construction reorganization of the territories vacated or re-cut to the city. In the process of demolition of obsolete buildings and structures, as well as the construction of new buildings, inevitably significant amounts of waste and construction debris arise that should be recycled as much as possible into secondary building materials (to carry out the so-called «recycling» of waste). Types of construction reorganization of urban areas are divided into traditional, widely known and standardized (repair, reconstruction, restoration), and innovative, arising in the processes of reorganization of society. Among the innovative types of construction reorganization, renovation is currently the most relevant, meeting the need to renovate the dilapidated housing stock of cities. The article discusses the main types of construction waste generated during demolition and new construction, as well as the technologies used for recycling these wastes during the renovation of territories and pavements of large cities.

Statement of the problem. Using the example of the leading construction organization in Voronezh, the article analyzes the shortcomings of the implementation of urban development projects and considers ways to solve them. Recently, the state of the natural environment of our cities has become a more urgent problem. This analysis will help designers in solving the problems of improving the architectural quality of the environment of new residential areas of the city of Voronezh. Results. As a result of the review and analysis of a number of implemented objects and the object planned for construction, ways to improve the architectural and artistic image of new districts are proposed, taking into account the features of the existing urban environment of Voronezh and current trends in advanced urban planning.Conclusions. Since any developer is primarily interested in the economic benefits of construction, he cannot express the true interests and needs of citizens, follow the historical traditions of the city. In the first stages of design, work should be performed on a competitive basis by order of the municipal authorities, even if the developer is the owner of the site intended for construction. The best project should be put up for auction among developers, providing the winner with the right to build in this territory.

Abstract The objective of this study is the comparison of green roof systems with conventional isolated and non-isolated ones in order to identify the potential energy savings of green roofs and the benefits provided in comparison with the cost of construction to the buildings. The region of interest is the Watergraafsmeer area in the city of Amsterdam. The method evaluates literature reports - mostly from 2003 to 2010 - that present the advantages of green roofs. Examples in real implementation of green roofs in USA, UK and Germany, retention of rainfall and a Life Cycle Assessment from a residential construction in Madrid will be introduced, showing the energy savings from insulation and heating/cooling that can be gained. All the reports have shown a reduction in energy costs and in runoff of water. Hence, costs and retrofitting potential completes the research. The age of buildings and the absence of insulation make green roofs an ideal alternative project for the retrofit of Watergraafsmeer.

Modern road constructions go through a whole range of different loads of static and dynamic nature; therefore, higher-quality materials and solutions are required for the roads of the corresponding class, ensuring their compliance with various climatic, geological and economic factors. Currently used road constructions have different basement, they can be of natural or artificial type. Designing a foundation on a concrete base is considered as the most enduring, however, there are a number of aspects that significantly affect their durability. Improving their reliability and quality is an important promising direction in the study of the use of new building materials. The article shows the possibility of improving the quality of the foundations of road structures through the use of poly-reinforced fiber-reinforced concrete. Compared with metal fiber, polypropylene fiber gives the desired effect of reducing the weight of the structure and the cost. There is a significant increase in the waterproof performance of fiber-reinforced concrete, which is especially important for drainage sections of road construction foundations. The authors determined that a significant improvement in the performance of fibrous concrete is achieved, when the polydisperse reinforcement of the concrete matrix use polypropylene (0.3 %) and steel (1.7 %) fiber. In this case, the first option has an impact on crack resistance, and the use of steel – on strength. Thus, with this ratio of reinforcement with various fibers, a synergistic effect of improving the static and dynamic indicators of fibrous concrete is achieved. According to authors, bench studies of reinforcement of fiber-reinforced concrete structures for the foundations of roads show their high economic efficiency and reduce the cost of 1 m3 of the finished structure to 16 %.

Contraction, downsizing, rescaling and subtraction are all words that characterise the urban planning debate with increasing frequency. Two components can be found at the basis of their circulation and declination.On the one hand, the recognition of the vast unused and disused real estate for which regeneration, reuse and renovation are not possible; on the other hand, the will and hope to rebalance the results of the hypertrophic twentieth-century urban development. The legitimacy of these instances is the wides pread belief that demolition and contraction are low-cost operations that can be financed by the owners of the property or through the usual equalisation and negotiation mechanisms. By using a case study, this paper will clear up amis understanding; it will explain how demolition and subtraction costs, which can be put on equal footing with renovations and, in some cases, new construction are sufficiently massive making their implementation within the public and public-private policies very difficult.

Building materials constitute about 60%-70% of the total cost of construction. Reduction in the use of conventional materials may not be possible; therefore, an alternative solution to use low cost materials would reduce the overall construction cost of a building. Industrial wastes, when recycled and reused as a building materials, not only aid in overcoming disposal problems, but also conserve natural resources, decrease energy use, and reduce pollution caused during manufacturing processes, and consequently reduce greenhouse gas emissions. Materials such as Copper slag, Phospogypsum and Fly ash, when used as supplements for sand and coarse aggregate in the manufacture of wall materials, reduce the cost of construction considerably. Additionally, construction of buildings using these materials leads to more energy efficient buildings and can gain additional weightage (points) in Green building certification. The aim of this paper is to highlight the cost reduction in using alternative wall material for construction, through detailed analysis in an apartment building in Chennai, Tamil Nadu, India. A comparative study between the different materials used such as, bricks, fly ash blocks and Alternative blocks made of industrial waste (Madhusudanan 2015)) were taken into consideration to assess the unit cost of each material. Similarly, a study of the cost performance between a load bearing structure and a framed structure was made, and it was found that the overall construction cost has a greater impact for a load bearing building when compared to a framed structure.

In order to reduce land conversion for settlement and traffic purposes, the German government introduced in 2002 the 30 ha per day objective and since then established a number of policies and projects in order to achieve this goal in 2030. On 1 January 2007, an amendment of the Federal Building Code came into force, which introduced an accelerated procedure for binding land-use plans for inner urban development (section 13a). The aim of this amendment was to simplify and accelerate the planning law for projects to support inner urban development. This paper seeks to answer the question of whether or not the accelerated procedure contributes to increased inner urban development by providing incentives for the reuse of vacant developed land, which are often contaminated sites. Based on the example of the city of Stralsund in the rural region of Mecklenburg-Western Pomerania, we explore the quantitative land development in the inner and outer area from 1990 to 2018 and calculate costs savings for developers and public authorities. The results reveal that, although the accelerated procedure has been widely applied in the city of Stralsund since 2007, its effect on increased inner urban development has been very limited. The magnitude of the cost advantage is rather small, so that the accelerated procedure is often not regarded as decisive for the decision of inner versus outer development. The accelerated procedure has reduced the administrative burden for developers and public administration; however, in order to reach the 30 ha per day objective, more tailored policy instruments are needed.
