How to calculate the project construction of the price?
Below small make up engineer will answer for you.
construction main price composition is mainly in four aspects: the screen body price, control system, computer audio, engineering construction.
Screen: the screen body price is mainly provided by the manufacturers are generally calculated according to the case, module, or square.
Control system, control system and the screen body is supporting for sale, according to the size of the display screen.
Computer audio: full color playback when need a computer synchronization to the content and the effect of music, single and double color with u disk import file only need to use computer to edit files.
Project construction: is the artificial cost.
a penny a cargo, advising clients to select products suitable for their own use, don't only look at the price.
So what methods of estimate price?
Construction of foundation engineering price in backfill earthwork excavation, concrete, steel and other materials and machinery, Labour cost.
This part of the offer is based on the volume of earthwork, concrete units, namely yuan/square, reinforced by weight for the quotation unit, namely yuan/ton, the construction of artificial in number of days for quoting unit, namely, yuan/man-days.
General valuation can be unified for the reinforced concrete, the volume of the valuation can appraisal in 1000-1500 yuan between, volume price is lower.
Based the volume according to the experience of general civil is roughly equal, and the top of the screen area of 40 square screen the general based volume probably about 40 square, actual need professional design institute to carry on the design parameters.
Steel structure framework of price structure with steel material, steel material processing, welding, auxiliary materials fee again.
Steel and materials of reprocessing offer is based on weight unit, namely yuan/ton, the welding is artificial days for quotation, namely, yuan/man-days.
General valuation can be unified as the weight of the steel material valuation, namely yuan/ton.
Steel material is in commonly 5500-7000 yuan/ton (
According to the market price adjustment)
, add in 1000-1500 yuan/ton (
According to the reprocessing method adjustment)
, welding general in 2000-3500 yuan/ton, artificial auxiliary material is controlled in 500 yuan/ton, such general steel structure construction in 9000-11000 yuan/ton (
In the led display project general framework weight can according to 0.
15 tons per square meter, if is post installation, cylinder according to 0.
4 tons/m estimation, double column will multiply.
Outside decoration engineering price structure has a decorative materials, decorative artificial, auxiliary materials costs.
Decorative materials, auxiliary materials offer is based on area unit, namely the yuan/square meters, adornment is artificial days for quotation, namely, yuan/man-days.
General valuation can be unified into the area of the decorative material valuation, namely yuan/square meters.
Aluminous model board (
The decoration is in commonly 450-650 yuan/square meters.
as a hexahedron, just calculate all of its surface area minus display area is the decoration area, plus 15% of the loss of processing, to the final area.
Weak electric wiring project price structure with cables, pipeline trough, the installation of pipeline trough, the pay-off artificial cost, etc.
Cable, pipeline trough and its installation in length for the quotation unit, namely yuan/meters, pay-off is artificial days for quotation, namely yuan/man-days.
General valuation can be unified for the wiring length calculation, because the price of line pipe, trough and specifications, installation method is different, this part quotation to experience, only the actual calculation, the line slot in practical engineering general can use the cloth of weak current engineering has been good, only if their construction according to the actual calculation.
High voltage cable specification is more, the market price change is bigger, so the big cross section of cable cloth in place by the party a in advance as much as possible.
Low voltage cables, 8 core network line generally valued at $4 m/root, shielding generally valued at $4 / root m soft wire, fiber optic general appraisal 8 yuan/meters.
For optical fiber each end need other material cost (an increase of 2000 yuan
Welding, tail fiber, etc. )
