LED display is a project project, for the project "first friends", including those cost subjects, budget steps are what matters are not starting.In addition, when faced with the quotation from LED display manufacturers, dozens of expense lists are also confused.

I. project budget procedure

Step 1: calculate the amount of work -- know what you‘re doing so you can be prepared

First of all, we should ask the engineering side for the project list, or compile the project quantity list according to the field survey.

LED display manufacturers said that if there is a bill of quantities in the project bidding documents, they should check the quantities before calculating the bidding price.If the bill of quantities is not provided in the bidding documents, the total amount of quantities must be calculated according to the drawings.If the bidding documents have provisions on the calculation method of the project quantity, the calculation shall be carried out in accordance with the prescribed method.

Only accurate calculation, do know what to expect, in order to be prepared for trouble, to ensure that there will be no mistakes

Step 2 determine the unit price and calculate the combined price

In the tender quotation, after calculating the amount of each sub-project, it is necessary to determine the unit price of each sub-project, and fill in the quotation in accordance with the format of the bill of quantities in the bidding documents, generally in accordance with the content of the sub-project quantity and the name of the project to fill in the unit price and price.In calculating the unit price, all the cost items constituting the sub-project shall be included.

Labor, material, machinery cost should be the market price computation that calculates according to the labor, material, machinery consumption of branch and itemized project and corresponding.

Generally speaking, contracting enterprises should establish their own standard price database and calculate the bidding price of the project accordingly.In the application of the unit price database for a specific project bidding quotation, the need to select the unit price of audit and evaluation and adjustment, is in line with the actual situation of the bidding project, reflect the market price changes.

Step 3 determine the subcontract project cost

The subcontract cost from the subcontractor is an important part of the bid price, sometimes a considerable part of the total contractor‘s bid price comes from the subcontract cost.Therefore, when preparing the bidding price, it is necessary to have a verified price to measure the price of the subcontractor. It is necessary to be familiar with the scope of the subcontract project and evaluate the ability of the subcontractor.

Step 4 calculate and repeatedly verify profits

LED display manufacturers say that profit refers to the overdue profit of the contractor. The goal of determining the value of profit is to consider that the maximum profit can be obtained while ensuring the competitive bidding price.The contractor shall determine the profit margin on the project in accordance with the market competition situation at the time of tender quotation.

Step 5: repeatedly review and calculate risks, and confirm the risk fund

The risk fund is an unknown quantity for the contractor. If the predicted risks do not occur completely, the risk fund may be estimated to have surplus, which is the surplus and profit added together is the surplus;If the risk fund is estimated to be insufficient, it is subsidized by profits

At the time of bidding, a reasonable cost ratio shall be determined by experienced professionals after analyzing the possible risk factors item by item according to the actual situation of the project scale and the project location.

Step 6 determine the bid price and adjust it in time

According to different quotation modes, the bidding quotation of the project can be obtained after summarizing and summing all the costs. However, the project bidding quotation calculated in this way cannot be regarded as the bidding price, because the calculated price may be repeated or omitted, and there may be deviations in the estimation of some costs.Therefore, some necessary adjustments must be made to the calculated project bidding quotation.

Ii. Detailed explanation of each item in the quotation of LED display screen
