Attached: Project budget steps
Step 1 Calculate the amount of work-only by knowing it in mind can you be prepared
First, ask for a project list from the engineering company, or compile a project quantity list based on site surveys.
If a project quantity list is provided in the project bidding documents, the project quantity must be checked before the bid price is calculated. If the list of engineering quantities is not provided in the bidding documents, all engineering quantities must be calculated according to the drawings. If the bidding documents stipulate the calculation method of the engineering quantity, the calculation shall be carried out in accordance with the stipulated method.
Only by calculating accurately and knowing well can we be prepared and ensure that there will be no mistakes.
Step 2 Determine the unit price and calculate the combined price
In the bidding quotation, after calculating the quantity of each sub-item, it is necessary to determine the unit price of each sub-item project, and fill in the quotation according to the format of the quantity table in the bidding documents, generally according to the content of the sub-item quantity and Fill in the unit price and the combined price for the project name. When calculating the unit price, all the cost items that constitute the sub-items of the project should be included in it.
Labor, materials, and machinery costs should be calculated based on the labor, materials, and machinery consumption of the sub-projects and their corresponding market prices.
Generally speaking, the contracting company should establish its own standard price database and calculate the bid price of the project accordingly. When using the unit price database to make bid quotations for a specific project, the selected unit price needs to be reviewed, evaluated and adjusted, which means that it conforms to the actual conditions of the bidding project and reflects the changes in market prices.
Step 3 Determine the cost of the subcontracted project
The project subcontracting cost from the subcontractor is an important part of the bid price. Sometimes a considerable part of the bid price of the general contractor comes from the subcontracting project cost. Therefore, it is necessary to have a verified price to measure the price of the subcontractor when preparing the bid price, to be familiar with the scope of the subcontracted project, and to evaluate the ability of the subcontractor.
Step 4 Calculate and verify the profit repeatedly
Profit refers to the overdue profit of the contractor. The goal of determining the value of the profit is to consider the maximum profit that can be obtained, but also to ensure that the bid price is competitive. When bidding and quoting, the contractor shall determine the profit rate on the project based on market competition.
Step 5 Repeatedly review and calculate the risk, and confirm the risk
The risk fund is an unknown number for the contractor. If the estimated risk does not occur all, there may be a surplus of the estimated risk fund. This part of the surplus and profit are added together to form a surplus; if the risk fund is underestimated, the profit will be used to subsidize it.
When bidding, an experienced professional should analyze the possible risk factors item by item and determine a more reasonable cost ratio based on the scale of the project and the actual situation of the location of the project.
Step 6 Determine the bid price and adjust it in time
According to different quotation modes, the bid quotation of the project can be obtained after summing up all the costs. However, the bid quotation calculated in this way cannot be used as the bid price, because the calculated price may be repeated or missed, or some There are deviations in the cost estimate. Therefore, some necessary adjustments must be made to the calculated project bid price.
Adjusting bid quotations should be based on the analysis of project profit and loss. Profit and loss forecasts should be carried out from multiple angles using multiple methods to find out the problems in the calculation, and take measures to reduce costs and increase profits, so as to determine the final bid quotation.
