How do supervision engineers do a good job of on-site visa

A construction site visa is a certificate signed by the owner and the construction contractor who invest in the construction project, according to the construction contract, on the responsibility events involved in the construction process beyond the contract price. The following is the knowledge I brought to you about how the supervision engineer can do the on-site visa work well. Welcome to read it.

1. Reasons for the occurrence of project visa

Due to the large investment scale, continuous improvement of technical content, long construction period, many types and specifications of equipment and materials, and rapid price changes, it is impossible for the project contract to make a complete prediction and agreement on the possible situations during the whole construction period. During the implementation process, due to changes in subjective and objective conditions, such as the owner's financial reasons, changes in the owner's functional requirements, and changes in construction conditions, it will also bring uncertainties to the whole construction process. Therefore, during the whole implementation of the project, construction site visas will occur.

second, the role of construction site visa

1. As an important basis for project settlement

The main basis for project settlement is: construction contract, bidding documents, drawings, design changes, site visa, quota and stage data compilation and other regulatory documents, and the site visa records the special expenses incurred in the construction site in written form, which is directly related to the vital interests of the owner and the construction unit and is an important basis for project settlement. In particular, for some projects whose bidding quotation is blocked, it is necessary to adjust the design change and on-site visa during settlement. On-site visa is the first-hand information to record what happened on site.

2. As the basis for handling the claim

Through the analysis and review of the on-site visa, it can provide the basis for handling the claim, and correctly calculate the claim cost and construction period.

III. Contents of construction site visa

The main contents of construction site visa include the following aspects:

(1) Technical visa without cost

Technical visa without cost is generally proposed by the contractor or proposed by the contractor at the suggestion of the owner, and signed by the authorized personnel of the owner or the supervisor during the project implementation.

(II) On-site economic visa

On-site economic visa generally includes:

1. Sporadic employment. Employment that has nothing to do with the construction of the main project on the construction site, such as handling and demolition beyond the fixed cost.

2. Sporadic projects.

3. Supplementary items of temporary facilities.

4. Concealed engineering visa.

5. slowdown. Economic losses of personnel and machinery caused by shutdown due to reasons other than the construction unit. Such as water supply and power failure, insufficient or untimely materials of the owner, revision of design drawings, etc.

6. Price confirmation sheet for bargaining materials. The settlement data compilation stipulates that the materials with bargaining price difference are allowed to be calculated, and the material price needs to be determined before construction.

7. Other expenses requiring a visa.

(3) time limit for a project visa

time limit for a project visa includes: water and power cut visas; Time delay caused by non-construction unit shutdown.

iv. There are problems with on-site visa at present

All supervision engineers who have been engaged in project investment control have this experience, and the handling of on-site visa is the most controversial part in project construction. There are more or less problems with the engineering visas we contact. On the one hand, the construction market is not standardized, on the other hand, all parties involved in the construction (including owners, supervisors and construction units) do not pay enough attention to them. Generally speaking, there are the following problems:

1. The contents of the project visa in the project construction contract are not clear or the specific operation regulations are not refined, resulting in insufficient basis for the visa in the construction process, and the scope and standards of the visa cannot be accurately grasped.

2. On-site engineering quantity pricing visa personnel are indifferent to cost management and control. On-site management personnel do not attach importance to visas and lack awareness of investment control. Some construction units are not clear about which fees need visas, and lack visa awareness. Under normal circumstances, the on-site visa needs to be signed by the owner, the supervisor and the construction unit to take effect. The lack of any one visa is irregular and cannot be used as the basis for settlement and claim.

3. On-site visa personnel lack understanding of the composition of the fixed fee. On-site visa personnel don't know the composition of quota fees, and they don't know the concept of each fee composition in the quota. Some visas also give visas for on-site construction fences, construction houses, and measures that should be considered by the construction party in bidding.

4. Lack of effective constraints on design. Some drawings are not detailed enough, the instructions are not comprehensive enough, the design is too rough, the economic control requirements in the design process are not enough, and multi-scheme demonstration is not carried out. Due to the lack of design management, there are a large number of contact sheets of construction first, and the data reflect that the designers only sign their names and have no relevant opinions, which brings great trouble to the visa work.

5. For the convenience of its own construction or other reasons, the construction party arbitrarily modifies the construction scheme that has been approved and confirmed by the supervision engineer and the owner's on-site representative, and the visa officer also signs and recognizes the increased labor, materials and mechanical shifts. In addition, there are duplicate visas and cross visas for the same project content, which are especially common in earthwork excavation, obstacle removal, project demolition and other projects.

6. The date of on-site visa does not match the actual situation. There are strict time regulations on the price of labor, materials and machinery and related policy adjustments. Some contractors arbitrarily adjust the visa time in order to get as much excess profits as possible.

7. False visa. For example, due to the owner's funds, the owner decided to cancel the construction of some areas of the basement during the early construction of a house building project. The owner and the supervisor have verbally greeted the owner to suspend the construction of a certain part of the basement until the design changes. However, after the construction, the date of the design changes was delayed, saying that this part has been completed according to the original drawings and requesting a visa for this part. If the site management personnel do not have certain professional ethics, it will inevitably lead to the loss of the interests of the owners.

V. How do supervision engineers close the on-site visa

It is an important work for supervision investment control to close the on-site visa. As an investment control engineer, we should do the following work well:

(1) Be familiar with the contract. Familiarity with the contract is the first step in investment control, and special attention should be paid to the terms of investment control. Because in many contracts, the owners will stipulate some special terms according to their own conditions and requirements. For example, one project requires that the contract and the on-site visa must be signed by the director before they can take effect, and the on-site visa without the signature of the director cannot be used as the basis for settlement and claim. ? (2), timely processing. On the one hand, due to the characteristics of engineering construction, many processes will be covered by the next process, such as foundation earthwork, and some will be demolished during construction, such as temporary facilities. On the other hand, all parties involved in the construction may change.

(3), earnestly perform their duties. Strictly controlling investment is the duty that the controller must perform. Using our professional knowledge, strict examination of on-site visas can avoid the appearance of visas that violate the regulations. Investment control supervision engineer should have professional knowledge of cost, be familiar with the basic knowledge of quota and relevant laws and regulations, and examine whether the visa is reasonable, correct and realistic from a professional perspective.

VI. How does the supervision engineer check the on-site visa

To check the visa form well, the supervision engineer should do the following work well:

(1) Verification of the visa content.

The contents of the visa must conform to the facts. Generally speaking, the visa is issued only for the contents not covered in the contract, and the review should focus on whether there is a necessary visa and whether there is a contract basis. For this piece, it is necessary to review it on site, consult the contract, bidding documents and other materials, and analyze and check it. It is necessary to make a good record of the work content that cannot be reviewed after the visa is issued.

(2), check the visa form.

the visa form should clearly describe the visa matters, have a detailed formula for the calculation process of engineering quantity, draw drawings if necessary, and attach measurement records and meeting minutes if necessary, and so on. The original basis should be complete and must not be altered. The review focuses on whether the filling is complete, complete, true and objective;

(3) Check the number of visas.

The visa engineering quantity should be rechecked and calculated, and the calculation formula and method should meet the relevant requirements. Such as earthwork, can be calculated by section method, grid method, etc. If there is a section, it should be calculated according to the section. Field measurement, according to the field measurement records accounting. Measurement review, according to the measurement review record calculation. According to the actual record, it should be calculated according to the original records such as labor/machine-team. The review of this piece focuses on whether the calculation basis is sufficient, whether the calculation process is detailed and whether the calculation result is correct;

(4) Synchronization of visas of relevant parties.

Now many projects are owned by the owners and supervisors, and even the designers are involved in the visa. Supervision engineer in the visa at the same time, to achieve * * * knowledge with all parties, it is best to * * * with visa. Avoid the supervisor signing and reporting to the owner and the designer, thinking that it is not true and has different opinions. In addition, * * * can also do a better job of auditing and controlling visa forms more accurately;

(5). Keep the data on file for future reference.

a copy of the signed list must be kept for future reference in case the contractor changes it. Once you have mastered the original parts, you will be fearless and have a good idea. ;
