Is the tentative amount in the budget equivalent to the quality margin? Which ones are included:

Provisional amount: a sum of money tentatively determined by the tenderer in the bill of quantities and included in the contract price. It is used for the procurement of materials, equipment and services that have not yet been determined or unforeseen at the time of signing the construction contract, the project changes that may occur during the construction, the adjustment of the project price when the adjustment factors agreed in the contract appear, and the costs of claims and on-site visa confirmation.

The provisional amount is the latest concept proposed in the 09th edition of the cost engineer examination textbook, which belongs to the component of other project costs in the valuation of the bill of quantities. It means an amount included in the contract for the cost of carrying out any part of the work, or for the provision of goods, materials, equipment, or services, or for the provision of unforeseen events. The provisional amount is the owner's reserve, which is the amount determined in advance by the owner's consulting engineer and filled in the tender documents.

The provisional amount shall be used in whole or in part by the supervisor after reporting to the employer for approval, or shall not be used at all. For each provisional amount approved by the employer, the supervisor has the right to issue instructions to the contractor to carry out the work or provide materials, engineering equipment or services. These instructions shall be completed by the contractor, and the supervisor shall make corresponding adjustments to the contract ** in accordance with the provisions of the change valuation principles and paragraph 1 agreed in the terms of the valuation principles for the change of the highway engineering standard construction bidding documents (2009 edition).

At the request of the Supervisor, the Contractor shall furnish all invoices, invoices, vouchers and bills or receipts relating to the provisional amount of expenditure, unless the work is valued on the basis of the unit or total price set out in the priced bill of quantities. (Excerpted from the bidding documents for the standard construction of highway engineering [2009 edition]).

The landlord's question"Budget"This concept is a bit vague, but as far as I can understand, there should be two scenarios:

1.The provisional amount on the general works budget. The construction company will list a provisional amount when bidding, but this value is generally stipulated by the owner, if the construction company ranks a tentative amount in the ** table is a disadvantageous factor for its own bid evaluation.

The owner stipulates that the tentative amount is mainly due to the consideration that there are some project contents that cannot be fully determined during the bidding, in order to provide a unified bid evaluation standard for the bidders to stipulate a tentative amount, the bidders only need to list this amount in their own ** table, generally speaking, there is not much significance. This amount has nothing to do with the quality margin.

2.Provisional amounts on the financial budget. Some engineering companies after winning the bid to prepare the project financial budget is to control the project cost, usually due to some unpredictable factors in the process of project construction, many companies will list a tentative amount when preparing the financial budget, the amount is mainly used for some uncontrollable or unpredictable expenditures.

The so-called quality warranty refers to the completion of the project due to the consideration that there may be some quality problems, the owner will deduct a certain proportion of the contract price as a deposit when paying, if once the quality of the project has a problem, when the engineering company is required to repair and its non-performance, the owner will use the quality deposit to repair itself is the so-called quality warranty, generally 10% of the contract price

Answer]: B, Teach Caution, Material, Imperial Filial Piety, pp. P221-P223

The total reserved proportion of the deposit shall not be higher than 3% of the total settlement of the project price; The contractor may use a bank guarantee instead of a reserve deposit.

Answer]: B2022 version of the textbook P220

According to the Notice of the Ministry of Housing and Urban-Rural Development and the Ministry of Finance on Printing and Distributing the Administrative Measures for the Quality Deposit of Construction Projects (Jian Zhi [2017] No. 138), "Article 7 The employer shall reserve the deposit in accordance with the contract, and the total reserved proportion of the deposit shall not be higher than 3% of the total amount of the project price settlement and general covering. Calling the state".

Answer]: B The test point involved in this question is the proportion of the reserved margin cracked and disturbed. For construction projects that use all or part of the investment, about 5% of the total amount of the project price shall be reserved as a margin for the old group.

Where a social investment project adopts the method of reserving a margin, the proportion of the pre-reserved margin may be implemented by reference.
