41 common problems in construction cost


5.

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.

Do you still need to calculate the installation and disassembly fee and off-site freight of large machinery? A: generally, the unit price of construction machinery shift includes the installation and disassembly fee and inbound and outbound freight of the machinery itself, but the installation and disassembly fee and inbound and outbound freight of the machinery itself are not included in the mechanical shift of large mechanical equipment.

For the materials supplied by Party A, since Party A is responsible for the procurement, the procurement cost here should belong to Party A, that is, the procurement cost of materials cannot be counted.

In other words, the electricity charge is included in the unit price of the machine shift and does not need to be calculated separately.

Because it is similar to the brick foundation wall with indoor and outdoor height difference, it is also an exposed wall on one side and buried in the soil on the other side.

Under what circumstances is the consumption quota of machine shift used? A: for general engineering projects, machinery costs are included in each quota item, so the consumption quota of machinery shift does not need to be applied separately.

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 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.

For example, a certain region stipulates that the water and electricity charges shall be deducted according to 7 / 1000 of the direct charges for civil engineering, of which the electricity charge is 4 / 1000 of the direct charges and the water charge is 3 / 1000 of the direct charges.

The chemical composition of primary steel and secondary steel is different, but their density is the same.

The transportation expenses from the temporary warehouse or stacking yard on the construction site to the construction site are included in the sub items of the quota.

For example, if the thread anchor length of 16 is 12 * 16 = 182mm, the anchor length should be 250 according to the provisions of not less than 250mm.

The machine shift included in each quota sub item has the content of electricity charge.

The unit price of construction machinery shift has included the machinery installation and disassembly fee and inbound and outbound freight.

If commercial concrete is used, you can ask the commercial concrete manufacturer to provide the concrete mix proportion.

How to calculate the parameter mixing amount of admixture in concrete if it is inconsistent with that in actual construction? Answer: the amount of various admixtures in the concrete shall be calculated according to the actual construction participation.

4.

Is the unit weight of the two the same? A: the secondary steel is ribbed deformed steel bar, but the average diameter is calculated.

If there is no meter installed on the construction site, how to deduct the water and electricity fee from the project fund during settlement? Answer: for accurate calculation, the water and electricity charges can be analyzed in detail from the budget and settlement statement and deducted according to the water and electricity charges contained in the quota.

6.03g101 anchorage length of stressed reinforcement at the lower part of non frame beam: thread is 12D and smooth circle is 15d.

9.

The transportation cost from the procurement site to the temporary warehouse or stacking site at the construction site is included in the fixed unit price of materials.

This calculation is more accurate, but the workload is too large.

However, generally speaking, after the materials supplied by Party A enter the construction site, they are handed over to the construction unit for safekeeping, so the safekeeping fee should be owned by the construction party, that is, the safekeeping fee can be calculated from Party A according to the regulations.

Which one should be executed? Answer: the value should be taken according to a larger value.

The purchase cost of steel, pipe, cable, cement and wood is 0.1%, and the storage cost is 0.2%.

1.

The purchase cost of general building materials is 0.2%, and the storage cost is 0.3%.

Where is the electricity charge included in the quota? How should it be calculated? Answer: the electricity charge in the quota is calculated according to the consumption of machinery shift, which is specifically included in the machinery charge.

Should the solid brick retaining wall built to prevent earthwork collapse be set with brick foundation or brick wall quota item? Answer: it is more appropriate to apply brick foundation.

When arranging the temporary layout of the construction site, the construction unit shall consider the location of the temporary warehouse and the stacking place on site, and shall not be too far away from the construction site..

Therefore, the unit weight of primary steel and secondary steel is the same.

For the purchase and storage fee of materials, local regulations are different, and it should be calculated with reference to the coefficient published by the local cost management department.

For example, in the quota of a certain place, the unit price per kWh of electricity is 0.63 yuan, while the unit price of electricity charged by the power industry department is 0.85 yuan, then the price difference of 0.85-0.63 = 0.22 yuan per kWh of electricity should be calculated from the construction unit.

2.

The purchase cost of heating and sanitation equipment is 0.1%, and the storage cost is 0.1%.

Where is the cost of transportation of building materials included? How to calculate the secondary transportation fee on site? A: the transportation cost of building materials is distinguished in this way.

However, the tensile reinforcement shall not be less than 250mm according to the minimum anchorage length of the reinforcement.

The primary steel is round steel and the secondary steel is ribbed deformed steel, and their chemical composition is also different.

8.

You can refer to the concrete mix proportion in the completion file of the project.

7.

If the thread anchorage length of 25 should be 12 * 25 = 300mm, the anchorage length should be 300mm.

For the installation project, the water and electricity fee is 7.6% of the labor fee, of which the electricity fee is 4.6% of the labor fee and the water fee is 3% of the labor fee.

1.

Generally, the local project cost management departments have a coefficient for the deduction of water and electricity charges in this case.

How should the purchase and storage fee of materials supplied by Party A be calculated? A: the material cost should include the purchase and storage cost.

The material procurement and storage fee of a local cost management department is as follows, which can be used as a reference.

3.

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.
