A resource-efficient method of installation of prefabricated monolithic floor slabs by increasing the degree of their construction readiness is proposed in the article. This effect is achieved by the reducing of their own weight and the use of fixed formwork. The reduction in the dead weight of the precast-monolithic floor slab is ensured by the use of light three dimensional lined forms of trapezoidal or rectangular shape, preferably made of expanded polystyrene during the installation of the floor slab. The use of fixed timber formwork will obviate the need for the later implementation of labor-intensive finishing and insulation works. Thus, the installed floor slab will have an increased degree of building readiness immediately after its manufacture, and will also reduce the weight of the structure, which in turn will reduce the material consumption and accordingly the cost of the supporting structures of the building.
The construction of multi-storey residential buildings is associated with many problems, since the underground part is exposed to a large number of risks during design and construction. The paper analyzed and proposed the most appropriate option for the device foundation for a multistorey residential building. An expedient option is revealed by comparing different types of foundations by technical and economic indicators: labor intensity, duration of work, the wages of workers and estimated cost.
The article discusses well-known and perspective constructive and technological systems for the installation of monolithic and precast-monolithic floor slabs of civil and industrial buildings. It shows examples and expediency of using all kinds of inserts made of plastic and other light materials and products for replacing a part of heavy monolithic reinforced concrete. An original resource-saving method for the installation of precast-monolithic floor slabs with a simultaneous increase in the degree of their construction readiness is proposed. This effect is achieved by reducing their own weight and the use of permanent formwork. Reduction in own weight of the precast-monolithic floor slab is ensured by the use of volumetric lightweight trapezoidal or rectangular inserts, preferably made of expanded polystyrene, during its installation. The use of permanent formwork will eliminate the need for the subsequent performance of labor-intensive finishing and insulation works. To confirm the effectiveness of using the proposed method of precast-monolithic floor slab installation, the operation of two floor slabs was modeled in the LIRA SAPR computing complex - the proposed reinforced concrete innovative slab and a solid reinforced concrete slab. Having analyzed the calculated forces, deformations and the corresponding consumption of reinforcement and concrete, comparative indicators were obtained for the proposed innovative slab and for a typical solid floor slab. As a result, significant savings in material and cost have been proven.
The article analyzes the main factors for the campsites placement, as well as the classification of campsites by type. The analysis of the regulatory framework for the camping operation in the coastal zone on the territory of the Russian Federation. The assessment of the main factors for the auto camping location, as well as the advantages of auto tourism in comparison with the other types of tourism. An economic examination of the investment project effectiveness for the construction of a camping site was conducted on the basis of such indicators as: net present value, profitability index, internal rate of return and payback period. In the process of managerial examination of the investment project for the construction of a camping site with a hotel and entertainment complex, an assessment of the project management effectiveness was carried out. A methodology for assessing the integral effectiveness of an investment project according to the following criteria of functional efficiency is proposed: economic, organizational, social, environmental, legal, energy, technological, psychological, political and ethical.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
