A, the calculation of quantities
If there is a bill of quantities in the project bidding document, it should be checked before calculating the bid price. If the bill of quantities is not provided in the tender documents, all quantities must be calculated according to the drawings. If the tender documents stipulate the calculation method of engineering quantity, it shall be calculated in accordance with the prescribed method.
Second, determine the unit price and calculate the total price.
In the tender offer, after calculating the partial quantities, it is necessary to determine the unit price of each partial project, and fill in the quotation according to the format of the bill of quantities in the tender documents, generally according to the contents of the partial quantities and the project name. When calculating the unit price, all the cost items that constitute the partial project should be included.
Labor, materials and machinery costs should be calculated according to the labor, materials and machinery consumption of partial projects and their corresponding market prices.
Generally speaking, contracting enterprises should establish their own standard price database and calculate the bidding price of the project accordingly. When applying the unit price database to bid for a specific project, it is necessary to review, evaluate and adjust the selected unit price, which is in line with the actual situation of the bidding project and reflects the change of market price. In all stages of the preparation of tender offer, tender offer is generally calculated in the form of table.
Third, determine the cost of the subcontract works
Subcontractor's subcontracting fee is an important part of the bid price, and sometimes a considerable part of the general contractor's bid price comes from subcontracting fee. Therefore, when compiling the tender price, it is necessary to have a verified price to measure the subcontractor's price, and to be familiar with the scope of the subcontract works and evaluate the subcontractor's ability.
Fourth, determine the profit.
Profit refers to the contractor's overdue profit, and the goal of determining the profit value is to consider that both large profits can be obtained and the bidding price must be competitive. When bidding, the contractor shall determine the profit rate of the project according to the market competition.
Verb (abbreviation of verb) Determination of risk fund
The contractor does not know the risk premium. If the predicted risks do not occur, then the predicted risk premium may have a surplus, and the sum of this surplus and profit is the surplus. If the risk premium is underestimated, use profit subsidies. When bidding, experienced professionals should analyze the possible risk factors one by one according to the scale of the project and the actual situation of the project location, and then determine a more reasonable cost ratio.
Six, determine the tender price
According to different bidding methods, the bidding quotation of the project can be obtained after all the expenses are summarized and summarized, but the bidding quotation of the project calculated in this way can not be used as the bidding price, because the calculated price may be repeated or omitted, and some expenses may be biased. Therefore, it is necessary to make some necessary adjustments to the calculated project bidding quotation. The adjustment of bidding quotation should be based on the project profit and loss analysis, and profit and loss prediction should be made from multiple angles by using various methods to find out the problems in calculation and take measures to reduce costs and increase efficiency, so as to determine the subsequent bidding quotation.
