Are plan adjustments during the construction process a design change? Do I need a design contact for

I think you should first look at what a design change is.

Design change refers to the adjustment of the design unit according to the requirements of the construction unit, or the modification, improvement and optimization of the original design content. Design changes should be issued in the form of drawings or design change orders.

Changing the construction time, sequence and other contents that are inconsistent with the original design of the relevant works are design changes.

The type of design change.

1. At the design disclosure meeting organized by the construction unit and attended by the design unit and the construction enterprise, the practice of changing the construction drawings with the consent of all parties proposed by the construction enterprise and the construction unit is a design change, and the design unit or construction unit is responsible for adding new drawings or design change descriptions for this purpose.

2. During the construction process, the construction enterprise encounters some specific situations that were not expected by the original design, which need to be dealt with; The resulting design changes. If the pipeline installation process of the project encounters equipment and pipe piers that are not considered in the original design, and there is no installation position at the original design elevation, etc., it is necessary to change the direction or elevation of the original design pipeline, and handle the design change or design change contact form with the consent of the design unit and the construction unit. Such design changes shall indicate the project project, location, reason, practice, specification and quantity, as well as the construction drawings after the change, and the design change shall be signed and confirmed by the party.

3. After the start of the project, due to the needs of some aspects, the construction unit proposes to change some construction methods, or increase or decrease some specific engineering projects, such as in some projects, due to the construction unit requirements to increase the pipeline, and then obtain the consent of the design unit to make design changes.

4. In the process of construction, due to construction and resource market reasons, such as materials or immature construction conditions, it is necessary to replace it with other materials, or it is necessary to change the specific design of some projects, etc., which can be used as a design change with the signature of both parties or three parties.

There are many ways to adjust the plan, you should first determine whether the plan adjustment made by the construction unit has an impact on the original design content or has a contradiction with the original design content, if so, the design change is formed at this time, and the construction unit makes a design change order or contact sheet, the construction unit communicates with the design unit, and the design unit confirms.

As for the balance increase you mentioned, it is generally not mentioned in the contract, and the original design does not or the original design does not meet the requirements of the construction unit, which can be understood as a design change in the macro sense, but the operation in the specific implementation process is different

One is according to the requirements of the construction unit, the construction unit issued a project confirmation sheet (or called the project contact sheet), the purpose is to make the intention of the construction unit clear in writing, to be signed and confirmed by the construction supervision unit, organize the construction, during the construction process, do a good job of letting the construction supervision personnel record at any time, so as to finally carry out the visa, and finally the visa.

In some places, it is required that there must be a change order and a visa form of the construction unit during the audit, in that case, you can make a change order first, and after the construction is completed, make a visa form (so that you don't have to do a project confirmation form).

Plan adjustments during the construction process are not design changes and do not require a design contact form. The surplus investment to make a new project is a design change, which needs to be designed with a contact form, which is stipulated in relevant documents.

Design changes are for a single project, and the two things you said are beyond the scope of the design change, not the design change

During the construction of the project, the owner's plan should be adjusted, and the design institute should be notified that it is a new project, and a new project design should be added. It belongs to the original design adjustment, and there should be design changes. In the construction drawing stage, the change construction drawing should be issued in time.

The surplus investment in new projects is not a design change, and should be approved by the new project.

The process of engineering design change order is as follows: due to design problems, the designer proposes a design change order, and the total amount of each change order cannot exceed the relevant national regulations; The change order will be handed over to the owner's project department, which will first be reviewed and signed by the supervisor, and then signed by the supervisor of the project department, and then submitted to the construction unit and signed.

The so-called engineering change, in the process of the implementation of the project, in accordance with the procedures agreed in the contract, the supervisor according to the needs of the project, issued instructions to the original design in the bidding documents or the construction plan approved by the supervisor in any aspect of the material, process, function, efficacy, size, technical indicators, project quantity and construction method changes, collectively referred to as engineering changes.

Management topics involved in engineering changes

Engineering changes involve a wide range of management topics, such as bill of materials management, change requests (ECRs) and change orders (ECOs), after-sales services, cost management, etc. The following is an explanation of the management information that needs to be obtained in the event of various changes

1. Immediate change: The user must be able to grasp the future supply and demand of the defective key parts, as well as the future supply and demand of the replacement materials, in order to effectively implement the immediate design and change work. In addition, in order to track the material status of the products that have been sold, users also need to use batch number management to understand.

2. Running out of changes: Users must be able to grasp the future supply and demand of old parts to know when it will "run out".

The process of handling engineering changes is:

1. The construction unit shall make changes to the original project design, and the employer shall issue a notice of change to the contractor in writing no later than 14 days before the change, and when the change exceeds the original design standard or the approved construction scale, it shall be reviewed and approved by the original planning and management department and other relevant departments, and the original design unit shall provide the corresponding drawings and explanations for the change.

The increase or decrease of the contract price caused by the change and the losses incurred by the contractor shall be borne by the employer, and the delayed construction period shall be extended accordingly.

During the performance of the contract, the employer requests to change the project quality standards and other substantive changes, which shall be resolved through negotiation between the two parties.

2. The contractor requires changes to the original project and controls the order

During construction, Party B shall not change the original engineering design without authorization. Otherwise, the expenses incurred and the direct losses caused by Party A shall be borne by Party B, and the delayed construction period will not be extended.

The rationalization suggestions put forward by Party B in the construction involve changes in the design drawings or construction organization design and the replacement of raw materials and equipment, which must be agreed by the engineer. If Party B changes or replaces without consent, Party B shall bear the costs incurred therefrom and compensate Party A for the relevant losses, and the delayed construction period shall not be extended.

The engineer agrees to adopt Party B's rationalization proposal, and the expenses to be incurred and the benefits obtained shall be shared or shared by Party A and Party B separately. Project change procedure: Before the change, the two parties shall agree on the compensation for the increase in the cost involved in the project change and the loss caused, so as to avoid affecting the progress of the project due to the dispute over cost compensation.

Change refers to various types of changes within the scope of the contract work carried out by the contractor in accordance with the design documents issued by the supervisor and the supervision change instructions, including the increase or decrease of the contract work content, the change of the contract engineering quantity, the design change caused by geological reasons, the change of the size and elevation of the structure according to the actual situation, and any work outside the contract.

The so-called engineering change, in the process of the implementation of the project, in accordance with the procedures agreed in the contract, the supervisor according to the needs of the project, issued instructions to the original design in the bidding documents or the construction plan approved by the supervisor in any aspect of the material, process, function, efficacy, size, technical indicators, project quantity and construction method changes, collectively referred to as engineering changes.

As far as I've done.

Design notice: This has not been contacted, it should be, the engineering bridge calls the unilateral changes made by the design institute in the project, and the blueprint modification notice is made.

Project contact form: with Party A, a formal written document, for later reference, involving important matters need to be stamped by both parties.

Work contact sheet: Not much different from the above, the difference is that this is similar to a diary, and the above is a monthly summary.

Design change: During construction, Party B finds that it does not conform to the on-site construction situation, or Party A modifies it for convenience.

Then notify the design institute of the changes to the drawings.

Change the design: Same as the basic purpose above.

The above five names are actually two themes, one is that Party B is in contact with Party A, and the other is that Party B is in contact with the design institute.

Maybe some ultra-formal projects will be used separately, and they have not been touched.

If there is an error in the drawing review in the early stage, it can be proposed in the drawing review record, and then the design institute will make a change. If it is found during the construction process, the design change negotiation record should be filled in, and the design institute will make the change. Both of them need to be signed and stamped by the four parties of construction, supervision, construction and design.

(1) First of all, the name of the project, the name of the drawing, the construction unit, the construction unit and other names should be filled in completely;

2) Specify the reason for the change: mainly due to the following types.

due to design errors;

Changes involved in special circumstances, such as inconsistencies between the bearing layer of the foundation and the actual survey;

changes due to the use of new technologies, new methods, and new materials;

Changes due to the functional requirements of the construction unit;

3) Specify the content of the change

Propose the parts that need to be changed to the design mainly according to the reason for the change;

For changes due to new technologies, new methods, and new materials, new process practices and material properties should be indicated;

The maximum time to accept the change that does not affect the duration of the project needs to be stated;

4) Fill in the opinions of all parties and sign and seal, and indicate the date.

Change the processing card, write the reason for the change, change the plan, and now sign by several parties

How can I improve it, and if I write all the changes clearly, it will be perfected? Don't be ambiguous, and be careful to avoid your own risks.

Design notice: This has not been contacted, it should be that the design institute unilaterally made changes in the project, and make a blueprint modification notice.

Project contact form: communicate with Party A, formal written documents, for later reference, involving important matters need to be stamped by both parties.

Work contact sheet: not much different from the above, the difference is that this is similar to a diary, the above is a monthly summary of design changes: during construction, Party B finds that it does not meet the on-site construction conditions, or Party A notifies the design institute to modify the drawings issued by the design institute for the convenience of use.

Change the design: Same as the basic purpose above.

The above five names are actually two themes, one is that Party B contacts Party A, and the other is that Party B contacts the design institute.

Maybe some ultra-formal projects will be used separately, and they have not been touched.
