LED display engineering construction price estimation method

led display price are the main body of the screen, the control system, the computer price of audio power amplifier, engineering construction etc.

 

Screen body and control system is by professional led display manufacturers provide (yuan/square meters, control system according to the screen body size and decide), a penny a goods, suggest the customer to choose suitable for their own use products, do not only look at the price.

 

Civil engineering price have a basic turkmen excavation backfilling materials such as, concrete, steel and machinery, labor cost. This part of the quotation is the volume of the earth, concrete for quoting unit, namely the yuan/square, reinforced by weight for quoting unit, namely the yuan/ton, construction of artificial to offer unit, namely for days to the yuan/man-days. General appraisal can unite for reinforced concrete volume valuation, can appraisal is in 1000 1500 yuan between, the volume is low price. According to the experience of civil foundation volume is generally and the upper part of the body area approximately equal screen, such as 40 square screen based volume in general about 40 party or so, practical parameters need professional design institute to carry on the design.

 

Steel structure frame of the price formation have steel material, steel materials processing, artificial, welding and auxiliary material cost. Steel and materials processing offer again are based on weight, quoting unit that yuan/ton, welding artificial is for quoting unit, namely days yuan/man-days. General appraisal can unite for the weight of the steel material price, namely the yuan/ton. Steel material generally is in 5500 7000 yuan/ton (according to the market price adjustment), add in like 1000 1500 yuan/ton (again according to the processing method), welding and artificial general adjustment is in 2000 3500 yuan/ton, auxiliary materials in 500 yuan/ton or so, such general steel structure construction is in 9000 11000 yuan/ton (excluding reprocessing). In the led display engineering in general frame weight can be in accordance with the 0.15 t/m2 estimation, if is pillar installation, cylinder 0.4 t/m according to estimate, double column is double.

 

The price of the decoration project constitutes a decoration materials, decoration, auxiliary materials costs. Artificial Decoration materials, auxiliary materials for quoting unit price is based on area, namely the yuan/square meters, adornment is for quoting unit artificially days, namely the yuan/man-days. General appraisal for decoration materials can unite the area valuation, namely the yuan/square meters. Lu: su board (double) adornment is in commonly 450 to 650 yuan/m2. The led display like one hexahedral, as long as all of its surface area calculation shows that for decoration area of minus the area, and 15% of processing for the final area that loss.

 

Strong or weak electric wiring project price formation have cable, pipeline trough, pipeline trough installation, pay-off artificial and other fees. Cable, pipeline trough and the installation is for quoting unit, namely the length of RMB/m pay-off artificial is for days, quote, that yuan/man-days unit. General appraisal can unite for wiring length calculated, the line pipe, trough prices and specifications, so different, this part of the installation method to offer to experience statistics, can only practical calculation, practical projects this line pipeline slot can use electricity engineering has generally cloth, if their good construction with only calculated. High voltage cables and specifications, so the market price changes bigger, so large cross-section cable by party a prior cloth in place as far as possible. Elv cable, the eight core network line general appraisal for 4 yuan/root meters, shielding soft wire general appraisal for 4 yuan/root meters, optical fiber generally 8 yuan/m valuation. For optical each end need to increase the other material cost 2000 yuan (welding, tail fiber, etc.).
