When our customer undertakes an LED display project, we need to know how to calculate the cost of the project and the quotation plan. Today, Lianhuiye Technology will explain to you: First, the price composition of the display screen fixed civil engineering foundation project has earthwork Materials such as excavation and backfill, concrete, steel bars, machinery and labor costs. The quotation in this part is based on the volume of earthwork and concrete, i.e. yuan/square meter, the quotation unit of steel bars is based on weight, i.e. yuan/ton, and the quotation unit is the number of days for construction labor, i.e. yuan/working day. The general valuation can be unified as the volume of reinforced concrete, and the valuation can be between 800-1200 yuan. The larger the volume, the lower the price. According to experience, the volume of the civil foundation is generally roughly equal to the area of the upper part of the screen. For example, the general base volume of a 50-square-meter screen is about 50 square meters. The actual parameters need to be designed by a professional design institute. Second, the price of the steel structure frame of the display screen consists of steel materials, reprocessing of steel materials, welding labor, and auxiliary materials. The quotations for steel materials and material reprocessing are based on weight, that is, yuan/ton, and the quotation unit for welding labor is days, that is, yuan/working day. The general valuation can be unified as the weight of steel materials, that is, yuan/ton. Steel material is generally 4000-5000 yuan/ton (adjusted according to market price), reprocessing is generally 700-1500 yuan/ton (adjusted according to reprocessing method), welding labor is generally 2500-4000 yuan/ton, and auxiliary materials are 400 Yuan/ton, so the general steel structure construction is 8000-9500 Yuan/ton (excluding reprocessing). In the LED display project, the general frame weight can be estimated at 0.15 tons/square meter. If it is installed on a column, the column body is estimated at 0.4 tons/m, and the double column should be doubled. Third, the price of the display screen decoration project consists of decoration materials, decoration labor, and auxiliary materials. The quotation unit for decoration materials and auxiliary materials is based on the area, that is, yuan/square meter, and the quotation unit for decoration labor is based on the number of days, that is, yuan/working day. The general valuation can be unified as the area valuation of decoration materials, that is, yuan/square meter. Aluminum-plastic panel decoration is generally 400-600 yuan/square meter. The LED display is like a hexahedron, as long as it calculates all its surface area minus the display area is the decorative area, plus 15% processing loss is the final area. Fourth, the price of the LED? large screen strong and weak current wiring project consists of costs such as cables, pipeline trunking, installation of pipeline trunking, and laying labor. Cables, pipelines, trunking and their installation are quoted in units of length, i.e. yuan/meter, and laying labor is quoted in days, i.e. yuan/working day. The general valuation can be calculated as the length of wiring. Since there are many price specifications for wire pipes and trunking, and the installation methods are different, this part of the quotation is difficult to count based on experience, and can only be calculated in practice. In actual projects, this line of trunking can generally be used in weak current projects. It has been laid out, if you do the construction by yourself, you can only calculate according to the actual situation. There are many specifications of strong electric cables, and the market price changes greatly. Therefore, cables with large cross-sections should be placed in place by Party A in advance as much as possible. Among the weak current cables, the 8-core network cable is generally valued at 5 yuan/meter, the shielded flexible wire is generally valued at 10 yuan/meter, and the optical fiber is generally valued at 6 yuan/meter. For each end of the optical fiber, an additional material cost of 300 yuan is required. .
