How much material can describe the slogan?

This topic examines the calculation of advance payment and installment payment. Deduction point: 500-500× 20%/60% = 3,333,300 yuan.

1. Prepaid material limit

The limit of prepaid materials is determined by the following main factors: the proportion of main materials (including purchased parts) to the project cost; Storage period of materials; Construction cycle.

For construction enterprises that should prepare materials all the year round, the material preparation limit can be calculated according to the following formula;

Material preparation limit = total amount of annual contract works * proportion of main materials/calendar days of annual construction * days of material reserve.

General construction projects should not exceed 30% of the current construction workload (including water, electricity and heating), and the annual installation workload of installation projects should be10%; The installation project with a large proportion of materials is allocated according to the annual planned output value of about 15%.

2. Deduction of reserve funds

The materials allocated by the contractor to the contractor belong to the nature of advance payment. After the implementation of the project, with the gradual reduction of the main materials needed for the project, it should be deducted in the form of offsetting the project price. Deduction method:

(1) It can be deducted from the time when the value of the main materials and components still needed in the construction project is equivalent to the amount of reserve funds, and the project price can be deducted according to the proportion of materials every time the project price is settled, and all of them can be deducted before completion. Its basic expression is:

T=P—M/N

T-deduction point, that is, deducting the accumulated workload when prepaying materials;

M-the limit of prepaid materials;

N-the proportion of main materials;

P-total contract price.

(2) The deduction method can also be that after the amount completed by the contractor reaches a certain proportion of the total contract price, the contractor starts to repay the employer, and the employer deducts the project advance payment from the amount payable to the contractor every time, and the employer deducts the total project advance payment one by one at least before the completion date stipulated in the contract.

(4) Payment of progress payment (intermediate settlement)

In the process of construction, the construction enterprise calculates various expenses according to the number of projects completed month by month (or image progress, or control interface, etc.). ), and pay the progress payment to the construction unit (owner) (that is, intermediate settlement).
