You can refer to the concrete mix proportion in the completion file of the project.
The price difference of electricity fee is calculated before tax, that is to say, the price difference of electricity fee does not participate in the fee collection, and tax can be calculated.
02 if the unit price of reconstruction machinery shift has included the machinery installation and disassembly fee and inbound and outbound freight, do you still need to calculate the installation and disassembly fee and off-site freight of large machinery? The commonly used unit price of construction machinery shift includes the installation and disassembly cost and inbound and outbound freight of the machinery itself, but the installation and disassembly cost and inbound and outbound freight of the machinery itself are not included in the mechanical shift of large mechanical equipment.
If commercial concrete is used, you can ask the commercial concrete manufacturer to provide the concrete mix proportion.
01 which item does the electricity charge belong to in the quota? How should I get it? In the quota, the electricity charge shall be calculated according to the consumption of machinery shift, which shall be specifically included in the machinery charge.
(the article comes from the Internet)..
05 if the quantity of additive parameters in concrete is inconsistent with that in actual construction, what method shall be adopted in calculation? The amount of various admixtures in the concrete shall be calculated according to the actual construction participation.
04 when is the consumption quota of machine shift used? For general engineering projects, machinery costs are included in each quota item, so the quota of machine shift consumption does not need to be applied separately.
That is, the electricity charge is included in the unit price of the machine shift and does not need to be calculated separately.
Specific method: deduct the water and electricity charges included in the quota, which is more accurate, but the workload is large.
However, for some independent mechanical shift, the consumption quota of mechanical shift should be applied, such as the pumping shift of water pump signed on the construction site.
Therefore, for tower cranes, pile drivers, Crawler machines and other large-scale mechanical equipment, the installation and demolition costs and mobilization and demobilization costs need to be calculated separately.
The machine shift included in each quota sub item has the content of electricity charge.
03 if the water meter and electricity meter are not installed at the construction site, how should the water and electricity charges be deducted from the project settlement? In fact, accurate calculation can be analyzed in detail from the budget and settlement book.
However, if the electricity meter is installed separately on the construction site and the electricity fee is paid directly to the electricity department, if the unit price of electricity fee charged by the local electricity department is different from the unit price of electricity fee contained in the quota, the price difference of electricity fee can be calculated from the construction unit.
