Basic knowledge of FIDIC contract

Abstract: FIDIC contract is a unit price contract, that is, when bidding, the unit price of each single project in b.q. order is fixed, and the work inspection and pricing depends on the quantity of work completed by the contractor, and the quantity of work is changing, which is clearly explained in paragraph 55. B. Q. the quantity of works provided by a single sheet will vary with the design and calculation depth of the consulting engineer, and there must be a gap with the actual construction. This is a reality, so it provides a profit opportunity for the contractor

key words: FIDIC contract, unit price contract, contract and compare the product composition, material property index, utilization value and relevant manufacturers. The full English name of the untitled bill of quantities document b.q.

b.q. is Bill of quantities. It is also referred to as BOQ, which is translated into bill of quantities in Chinese. Other tenders are called price schedules. In the contract, the b.q. sheet is usually an independent booklet, which is the main basis for calculating the bid price when bidding and quotation, and also an important basis for the contractor to calculate the project funds with the owner through the consulting engineer

b.q. single is usually divided into hardworking sub items in the structural form, so that users can classify and search. Taking housing construction projects as an example, such sub items are generally divided by process, which may include site cleaning, earthwork excavation, concrete process, bricklaying process, asphalt process, capping process, woodworking process, trench joint process, steel structure, water supply and drainage pipeline, plastering process, water and electricity, oil paint, interior decoration and enclosure, etc

the table of each b.q. sheet is composed of several vertical columns. The leftmost column is willing to do a good job in technical services and consulting to promote the development of new polyurethane materials. The first column is the project serial number, the second column is the technical description of the single project that needs to fill in the unit price, and the third column is the specified quantity of the single project (actually the estimated quantity of the consulting engineer), The fourth column is the specified quantity of the project (it is blank at the time of bidding, which should be calculated and filled in by the contractor item by item at the time of bidding). The vertical column on the far right is the subtotal price obtained by multiplying the quantity in the third column by the unit price of the quantity in the fourth column (it is also blank at the time of bidding, which should be calculated and filled in by the contractor at the time of bidding). The sum of the figures in the rightmost column is listed at the bottom of each b.q. sheet. The total quotation of the Contractor's project bid can be obtained by adding the results at the bottom of each item

The biggest feature of FIDIC contract is the unit price contract. Because of this feature, many claim skills have been produced. In short, unit price contract is to fix the unit price of each single project in the b.q. list when bidding, while the work inspection and pricing depends on the quantity of work completed by the contractor, and the quantity of work is changing, which is clearly explained in Article 55. B. Q. the quantity of works provided by a single sheet will vary with the design and calculation depth of the consulting engineer, and there must be a gap with the actual construction. This is a reality, so it provides a profit opportunity for the contractor

the total contract price of FIDIC contract is only the total amount that can be used for reference when comparing the bid prices. After signing the contract, the actual workload on site is either greater or less than the workload specified in the contract. The total contract price of no contract is consistent with the total completion price. The total contract price can be used as the numerical basis for calculating the performance guarantee, advance payment, project retention money, delay compensation, etc., which is another function of it

the contractor must be familiar with and digest the project content in the b.q. list of the contract, and must not miss any detail of it, and be clear about his quotation scope and relevant, otherwise it will be difficult to determine whether the work task arranged by the owner belongs to the contract content, and it will inevitably become passive after being confused with the owner's baton. A competent contractor is often good at looking for omissions in the b.q. list, that is, looking for the gaps in the b.q., which is often heard in overseas projects, and looking for opportunities from it, ultimately making the contract amount greater than the contract amount. However, this is not absolute. If the unit price quoted by the contractor in the contract is very low and below the cost line, it is better to do less, because the more you do, the more you pay

fidic contract is a unit price contract

fidic contract is a unit price contract, which emphasizes the separation of quantity and price, that is, the engineering quantity in b.q. is separated from the unit price, and the quantity changes (refers to the engineering quantity) and the price remains unchanged (refers to the unit price) in the process of use, which is different from the project budget method that was widely used in China

when bidding, the Contractor does not quote the total price, but the unit price. The total bid price of the project can be summarized only after the unit price is multiplied by the quantity approved by the consulting engineer. This total bid price is just a concept, or it just provides a rough reference value for the owner and the consulting engineer when comparing the price of each company. The total income actually obtained by the contractor is obtained through work inspection and valuation in the process of performance. Although the total bid price of the project is similar, due to the different unit prices of various items in the b.q. list at the time of quotation, the Contractor's profits will also be different

b.q. sheet was originally unique in ice contract, which can be said to be a typical British project management mode. FIDIC contract uses this payment method, that is, the owner pays according to the actual workload completed by the contractor. When using clause 60 of FIDIC contract, people often say that work inspection and pricing refers to checking the actual completed quantities, multiplying these quantities by the unit price in the b.q. sheet, and then calculating the amount payable to the contractor based on this, and threading the samples into the holes of the bottom plate in the two clips first

b.q. the characteristic of single payment method is that after analyzing the drawings and technical specifications, the consulting engineer breaks down the whole project into several details, and then marks the estimated quantities of each construction process after calculation, and writes them on the tender. When bidding, the contractor only needs to fill in the corresponding unit price, so that after multiplying the estimated quantities, all the details can be summarized to obtain a total price, that is, the contract amount at the time of signing

the most common way to test the hardness of steel with B.Q filled in the unit price is to file and wipe on the edge of the workpiece with a file, and the hardness can be determined by the depth of the scratch on its surface Single has two main functions in the contract:

(1) as the basis for work inspection and pricing and the owner's payment

(2) as a reference when evaluating engineering change orders

the actual income of the contractor is not directly related to the project quantity given in the b.q. order. One of the reasons is that no matter whether the consulting engineer issues a project change order or not, the work completed by the consulting engineer's on-site supervision and on-site retest is used in the inspection and pricing
