Commonly used methods for cost auditing of construction projects
The reform of construction project cost in my country has just been implemented. The original fixed quota valuation and the reformed bill of quantities valuation method are in a dual-track parallel, gradually transitional stage, and run through the construction drawing budget. , preparation of base bids and final accounts of projects and other various pricing links. The difficulty of cost authenticity audit has further increased. On the premise of improving audit quality, in order to improve the efficiency of audit work and save audit costs to the greatest extent, it is particularly important to adopt different audit methods according to the different characteristics of construction projects. Based on my many years of experience in cost auditing, the author believes that there are the following methods for auditing construction project costs that can be discussed with peers.
, comprehensive audit method. It refers to the method of reviewing all projects one by one according to the preparation sequence of national or industry construction project budget quotas or the sequence of construction. The specific calculation method and review process are basically the same as those for preparing construction drawing budgets. The advantage of this method is that it is comprehensive and meticulous. The audited project cost errors are relatively few and the quality is relatively high. The disadvantage is that the workload is large. The comprehensive audit method must be adopted for units with relatively small project quantities, relatively simple processes, weak technical strength of cost preparation or quotation units, or even low credibility.
, standard chart audit method. It refers to a method that for engineering projects that use standard drawings or are constructed through drawings, the audit force is first concentrated on preparing standard budgets or final cost accounts, and this is used as a standard to conduct comparative audits. Projects designed according to standard drawings or constructed according to general drawings generally have the same structure above the ground. Auditing efforts can be concentrated to scrutinize a budget and final cost, which will be used as the standard cost of such standard drawings or the engineering quantity of such standard drawings as the standard, and the audit will be compared . Locally different parts and design changes can be reviewed separately. The advantages of this method are short time, good effect, and easy finalization. The disadvantage is that it is only applicable to projects designed or constructed according to standard drawings, and its scope of application is small.
, Group calculation audit method. Divide sub-projects into several groups, and group projects that are adjacent and have certain internal connections into one group, audit and calculate the quantities of a certain sub-project in the same group, and use the relationship between the project quantities that have the same or similar calculation basis, Then judge the quantities of several other sub-items in the same group. This is a way to speed up the project quantity audit.
