Organization of construction

The construction organization project provides for the laying of a 35 kV cable line. The construction master plan was developed on a scale of 1:500 for the construction period, taking into account the work of the preparatory period. Temporary solid fencing of the construction site is provided in accordance with the requirement of GOST 23407-78. The entry and exit of transport and construction equipment to the construction site is organized from the side of the road network. At the exit from the construction site, it is planned to wash the wheels of vehicles with circulating water supply. The laying of the cable line is carried out in open and closed ways. Earthworks for the construction of pits and trenches are carried out with an EO-3323A type excavator with a 0,65 m3 bucket and a Vermeer Navigator D20x22A installation. The mechanization of construction works is complex, using mechanisms such as: EO-3323A, Vermeer Navigator D20x22A, KS-35715, ASF-K-2-07, DM-64. Work will be carried out in 2 shifts.
Materials are stored in open warehouses with a margin of no more than 5 days. Provision of construction materials is provided from the enterprises of the construction industry. Amenity premises for construction workers, with a maximum number of employees of 24 people, are provided in mobile change houses. The total duration of construction, taking into account the work of the preparatory period, is 4 months. Construction waste generated during construction is removed by a specialized organization to a licensed solid waste landfill. The requirements for the organization of the construction site, labor protection and hygiene of construction work, methods of construction work, methods of instrumental control over the quality of construction, labor safety measures, and environmental conditions are met in the project in full. The use of materials and mechanization specified in the project is justified by calculations and conditions for the production of work.
