Before we decide to do the LED display project, we always make a detailed budget report. In this report, we have to specify whether it is outdoor or indoor, because the project cost is completely different in different locations. For example, the budget of P4.81 outdoor rental LED display project is basically composed of the following four types of project costs.
P4.81 The cost included in the outdoor rental LED display quotation:
1. Quotation of the screen body: including the total area of the screen body;
2. Supporting equipment: including control system, computer, audio and power amplifier, power distribution cabinet, video processor;
3. System engineering: including steel structure, power wiring, installation and commissioning, transportation costs, etc.
P4.81 Cost of outdoor rental LED display:
Basic engineering cost:
The so-called basic engineering is to fix the P4.81 outdoor rental LED display screen to the civil foundation engineering. The price of the project consists of: earth excavation and backfilling, concrete, steel bars and other materials, machinery, and labor costs. The quotation for this part is based on the volume of earthwork and concrete, that is yuan/square, the weight of the steel bar is the quotation unit, that is yuan/ton, and the labor for construction is quoted in days, that is yuan/man-day. The general valuation can be unified as the volume valuation of reinforced concrete, which can be estimated between 700-1,000 yuan, and the larger the volume, the lower the price. According to experience, the volume of the civil foundation is generally roughly the same as the area of the upper screen. For example, a 40 square screen generally has a foundation volume of about 40 square meters.
Strong and weak current wiring project cost:
P4.81 The cost of the strong and weak current wiring project of the outdoor rental LED display project includes: the installation of cables, pipeline troughs, pipeline troughs, and labor costs for setting-off. Cables, pipeline troughs and their installation are quoted in terms of length, that is, yuan/meter, and manpower is quoted in days, that is yuan/man-day. The general estimate can be calculated as the length of the wiring. If you construct by yourself, you can only calculate it according to the actual situation. There are many specifications of high-power cables, and the market price changes greatly. Therefore, the cables with large cross-sections should be placed in place by Party A in advance. Among the weak current cables, the 8-core network cable is generally estimated to be 4 yuan/meter, the shielded flexible wire is generally estimated to be 10 yuan/meter, and the optical fiber is generally estimated to be 6 yuan/meter. For each end of the optical fiber, an additional material cost of 280 yuan (fusion splicing, pigtail, etc.) needs to be added.
Steel structure frame cost:
P4.81 The cost of outdoor rental LED display steel structure frame includes: steel material, steel material reprocessing, welding labor, and auxiliary material costs. The quotations for steel materials and reprocessing of materials are all quoted in terms of weight, namely yuan/ton, and welding labor is quoted in days, namely yuan/man-day. The general valuation can be unified as the weight valuation of steel materials, that is, yuan/ton. Steel material is generally 4500-5500 yuan/ton (adjusted according to market prices), reprocessing is generally 600-1500 yuan/ton (adjusted according to reprocessing methods), welding labor is generally 2000-3500 yuan/ton, and auxiliary materials are 500 About RMB/ton, so the general steel structure construction is 7000-9500 RMB/ton (excluding reprocessing). In the LED display project, the weight of the general frame can be estimated at 0.15 tons/m2. If the column is installed, the column body is estimated at 0.4 tons/m, and the double column should be doubled.
Cost of exterior decoration project:
P4.81 The cost composition of the exterior decoration project of the outdoor rental LED display includes: decoration materials, decoration labor, and auxiliary materials. The quotation of decoration materials and auxiliary materials is based on the area, namely yuan/square meter, and the decoration labor is based on the number of days, that is yuan/man-day. The general valuation can be unified as the area valuation of the decoration material, that is, yuan/square meter. Aluminum composite panel decoration is generally 450-650 yuan/square meter. The LED electronic display screen is like a hexahedron, just calculate all its surface area minus the display area is the decorative area, plus 15% of the processing loss is the final area.
The biggest feature of P4.81 outdoor rental LED display is rich in scenes, large screen size, and gorgeous content. It can also save some cost and budget, and it does not require a one-time purchase like other conventional displays. Through the above articles, everyone should understand where the money is spent on installing outdoor LED displays. It is not unreasonable to say that you pay for what you pay for.
