First of all, please ask a professional audit company to audit.
As the compilation of construction project settlement is a complicated and meticulous accounting work that combines technology and economy, it not only requires editors to have certain professional technical knowledge, including a series of systematic architectural engineering knowledge such as architectural design and construction technology, but also requires editors to have higher budget professional quality and contract management level. But in actual work, no matter the level is good or bad, there will always be some mistakes. If the quota conversion is unreasonable, due to the continuous emergence of new technologies, new structures and new materials, the items and contents that are missing or need to be supplemented in the quota are also increasing. However, due to the lack of investigation and reliable first-hand data, the settlement quota or supplementary quota contains more irrationality; Secondly, there is a general overestimation in settlement. In order to get more income, some construction units do not start from improving management, improving project quality and creating social reputation, but artificially increase the project cost by means of exceeding the project quantity, high quota unit price and various excuses. In addition, because the project cost is composed of many items, it changes frequently, the calculation program is complicated and the calculation basis is different, which is easy to cause errors.
In order to correct the above mistakes, it is necessary to invite a professional audit company to audit. Although the project audit is an after-the-fact control, although it is "better late than never", it is also very effective. For example, the Fushi Villa project has a building area of 134 1M2, a building height of 1 1m and a basement depth of 3m. Through professional audit, the unit project cost decreased from 2053 yuan /m2 submitted for review to 65438 yuan +0428 yuan after audit. Century Space Building project, with a construction area of 22,000 square meters, 24 floors above ground, and 1-6 floors are podium buildings, with a construction area of 7,200 square meters and 3,600 square meters underground. Through the audit, the unit cost was reduced from submission cost 1.977 yuan/m2 to audit cost 1.686.
Compared with the project cost of tens of millions or even hundreds of millions, the audit fee can even be ignored, but the economic benefit is very good. Therefore, at present, most real estate companies will ask audit companies to do the last pass for them, and a little audit fee will save a lot of money on the project cost.
Second, choose the best audit unit through bidding.
At present, there are many engineering cost consulting companies in society, and the good and the bad are mixed. So we should choose the best audit company through bidding. Generally, five engineering cost consulting companies are invited to bid, and their bidding documents are compared by issuing bidding documents, mainly comparing their qualification grade, business license, contract performance, performance certificate, personnel and equipment, audit plan and schedule, quotation, etc., and the best unit is selected by comprehensive scoring method. Among them, the audit plan is particularly important. We require the specific auditors of the audit unit to calculate the quantities item by item, check the quota subheads one by one, and check the unit price of materials one by one. Other methods such as spot checks cannot be used. At present, most construction units are private enterprises, and their audit reconciliation is carried out item by item. If the audit unit only checks, the construction unit has no opinion on any place with high audit, and the owner is not satisfied, but the construction unit will propose any place with low audit. If the audit is not calculated in advance, not only the audit speed is full, but also the quality is not high, and both the owner and the constructor are not satisfied. Therefore, we emphasize that audit institutions should check one by one. Secondly, the performance of the audit company is very important: when we bid for the audit of villa projects, we pay special attention to whether they have done villa projects before and whether they have done a good job in the decoration audit of villas. When bidding for the audit of Century Space Building, we pay special attention to whether they have done the audit of high-rise office buildings or residential buildings before, and whether they have done the audit of prestressed engineering, steel structure engineering, steel bar planting and carbon fiber reinforcement, because only when they have done similar projects will they be more experienced. In addition, audit fees are also very important. For example, some units charge fees according to the reduction or exemption, and some units charge fees according to state regulations. In a word, bidding can not only reflect one's professional ability, but also reduce the audit cost. For example, the audit fees of Fushi Villa Project and Century Space Project are much lower than those of Shanghai.
III. The submitted audit materials shall be complete:
Because the audit company is not familiar with the site situation, they audit completely according to the completion settlement data provided by the owner, which requires us to be responsible for the data submitted for audit. In general, the materials submitted for review are:
1, project completion drawing;
2. General contracting contract;
3, all kinds of professional designated subcontracting;
4. On-site visa, technical verification sheet and design change;
5. Materials and equipment approved by Party A;
6, meeting minutes, contact list, geological survey report, etc.
As-built drawings are generally drawn by the construction unit. In order to settle more accounts, they often draw those without construction. According to the as-built drawings, combined with hidden visas, on-site visas and design changes, review and calculate, and check whether all the work is completed according to the drawings and contract provisions, and whether there are any missing items or items. Carefully verify whether each project change is really implemented, whether it should be increased or decreased, and seek truth from facts. Therefore, as the owner's audit representative, the quality of as-built drawings should be strictly controlled. As-built drawings should be reviewed, signed and sealed not only by the supervisor, but also by the owner's project manager.
There are many loopholes in design changes in project completion settlement, and some have design changes but no construction; Some constructions have been reduced, but there are no corresponding design changes; In addition, the engineering quantity of design change is far greater than the actual construction quantity; The list goes on. Therefore, at the time of settlement, our personnel are required to have patient and meticulous working methods, carefully calculate the engineering quantity, do not be afraid of trouble, and check more on the spot. For example, in the drawings of Century Space-Time Building, it is required that the ceiling of the 1-6-storey podium with a height of 4 meters should be completely approved with interface agent, then the mixed mortar of 1: 1: 4 should be brushed, and then white cement should be embedded. However, in the actual construction, considering that there will be fine decoration in the future, there is no construction. If you don't check carefully, the cost of painting and the whole house will increase by about 200 thousand.
Four, the content of the project cost audit
In the process of audit, our owner should communicate and coordinate with the audit unit, based on the contract, combined with the bidding documents, agreements, meeting minutes, geological survey data, engineering change visas, materials and equipment price visas, concealed engineering acceptance records and other completion materials, and on the basis of the completion drawings, do a good job of project audit in a realistic way according to relevant documents, mainly to review whether the engineering quantity is correct, whether the unit price is reasonable, whether the cost calculation is accurate, design changes, etc.
1, engineering quantity audit
The error of engineering quantity is divided into positive error and negative error. The positive error often shows that the actual excavation height of earthwork is less than the outdoor design height, and it is still calculated as planned. The area occupied by holes and ditches is not deducted; The volume of inner ring beam and lintel of the wall is not buckled; Reinforcement calculation often does not buckle the protective layer; Repeated calculation of reinforced bars or stirrups at the joints of beams, plates and columns. The negative error is manifested in the calculation of engineering quantity completely according to the theoretical size. Therefore, it is most important to be familiar with the calculation rules of construction drawing quantities. One is to distinguish the calculation range, such as the division of foundation and wall in masonry engineering, the division of column height in concrete engineering, the division of beam and column, the division of main beam and secondary beam, etc. The second is to distinguish the scope of restrictions. For example, if the height of a building is more than 3.6m, it is necessary to decorate the ceiling to calculate the scaffold cost, and the cast-in-place reinforced concrete member can be considered as the ultra-high formwork support cost. Third, it is necessary to carefully check whether the calculated size is consistent with the illustrated size to prevent calculation errors. Fourth, carefully divide the interface between professional subcontracting and general contracting, and cannot be calculated repeatedly. The engineering quantity audit of visa information mainly refers to the verification of on-site visa and design change notice according to the actual situation, so as to be realistic and reasonable in measurement. During the audit, we should do a good job of investigation and study to review its rationality and effectiveness. Don't measure the visa as soon as you see it, put an end to and prevent unrealistic expenses.
2. Apply for unit price review
The project cost quota is scientific, authoritative and legal, and its form and content, calculation unit and quantity standard must be strictly implemented by anyone, and can not be raised or lowered at will. When reviewing and applying the budget unit price, we should pay attention to the following issues:
Directly apply the fixed unit price audit-first pay attention to whether the project name and content adopted are consistent with the design drawing standards, such as component name, section form, strength grade (concrete grade, cement mortar ratio), etc. Secondly, whether the project is applied repeatedly. Such as the leveling layer under the surface of the block; Asphalt coiled material waterproof layer, cold priming oil under asphalt gas barrier; Iron parts of prefabricated components; Water supply and drainage facilities belonging to the category of building engineering. This phenomenon is particularly common in projects with comprehensive quota budget, especially when the project is related to general contracting and subcontracting, which often leads to duplication of engineering quantity. In addition, whether the fixed price of main materials is reasonable or not, we should make market inquiry for special materials, grasp the price dynamics and improve the accuracy of engineering valuation. For example, the comprehensive unit price of carbon fiber reinforcement project and steel bar planting is 30% lower than the quotation of the construction party through market inquiry.
