Construction can be organized only after the engineering change is approved according to the approval authority of this method; (2) The project change must adhere to the spirit of high responsibility and strict scientific attitude.
4) The technical feasibility of the change and its possible impact on subsequent construction.
The Contractor shall submit the “change report” after communicating with the supervisor and construction management according to the “change instruction” and the “review opinions on engineering change price” of the supervision organization The supervision organization shall review the “change report” and sign the “engineering change review opinions”.
The supervision organization shall review the Contractor’s construction scheme and quotation document respectively.
2) Basis, scope and content of change.
(4) the price principle of the changed project, the preparation of unit price, the unit price analysis and summary table of the changed project.
Define that engineering change is divided into major design change and general change.
The “change design report” shall be filled in to explain in detail the reasons for the change design (soil sample analysis, deflection detection or bearing capacity test data shall be attached for soft foundation treatment), the change scheme (sketch and on-site pictures shall be attached), and the technical and economic comparison with the original design (if there is no unit price, fill in the estimated cost) and apply for approval according to the approval authority of these measures.
If the contractor puts forward the reasons and basis for the difficulty in implementing the change, the supervision organization shall determine to cancel, change or not change the original change letter of intent after consultation with the employer and the contractor.
Once the design is approved, it shall not be changed arbitrarily.
After reviewing the construction scheme, it shall review it separately; review the change quotation document, communicate with the contractor and the on-site construction management unit on the unit price or price of the changed project during the review process, and submit it to the on-site construction management unit with “review opinions on project change price”.
Change report format (1) reason and basis of change (the reason for the change shall explain the contract agreement and the actual situation on site or the new requirements or design change notice.
If the construction scheme of the changed project has been approved, a copy of the approved construction scheme can be submitted for future reference; the quotation document must be quoted in combination with the approved construction scheme and the unit price principle agreed in the contract, and the impact of the changed project on the contract investment and cost Analysis results of contract duration.
If it is not approved, it shall not be constructed according to the changed design; in the actual project, the general change of the project is usually in the form of meeting minutes, and all parties involved reach a consensus.
General engineering change principle (1) design documents are the main basis for arranging construction projects and organizing construction.
3) Impact of change on project quality, price and construction period.
On the premise of ensuring the project quality standard, the project change shall be considered when there are significant benefits in reducing the project cost, saving land and accelerating the construction progress; (3) For engineering change, careful investigation shall be conducted in advance and graphic data shall be provided.
The requirements are the same as the current design to meet the construction needs.
(3) The construction scheme of the changed project and the supervisor’s reply to the construction scheme.

No matter what causes the change, after confirming the change, the supervision organization must first issue “change instructions”.
If the geological factors on site change, corresponding supporting materials shall be attached, and the change basis shall accurately express the agreement of the contract terms and the existing actual situation).
Other changes are general changes.
(6) when the supervision agency reviews the change quotation submitted by the contractor, it shall review and report to the employer according to the approved change project implementation scheme according to the following principles: 1) If there is a sub item applicable to the changed work content in the bill of quantities of the construction contract, the unit price of the sub item shall be adopted.
The “change instructions” issued by the supervision organization The reason for the change shall be explained, the Contractor shall be notified to make the change according to the provisions of the contract, and the construction scheme of the changed project (if there is an existing scheme, it can be implemented according to the approved scheme, which can only be described in the quotation document, and the approved scheme shall be submitted for future reference) and the quotation document of the changed project shall be submitted by the contractor according to the “change instruction” Submit the changed construction scheme and quotation document of the changed project according to the requirements of the contract, and the construction scheme and quotation document shall be submitted separately.
Management of major design change (1) The process of change proposal, change instruction, change quotation, change determination and change implementation shall be carried out in accordance with the procedures agreed in the construction contract.
(2) the scope, content and construction time of the change project (implementation process or plan arrangement).
2.
in the process of engineering construction in terms of project development task, project scale, design standard, overall layout, project layout, structural type of main buildings, important electromechanical and metal structure equipment, treatment measures for major technical problems, etc Design changes have a significant impact on benefits.
5.
(2) the supervision organization may issue a change letter of intent to the contractor according to the contract and require the contractor to submit a change implementation plan (including the plan, measures and completion time for implementing the change work) on the contents of the change letter of intent ; review the Contractor’s change implementation plan, put forward review opinions, and issue change instructions after the consent of the employer.
1) Reasons and necessity of change.
6.
3) If there is no applicable or similar unit price in the bill of quantities of the construction contract, the unit price prepared according to the principle of cost plus profit may be adopted.
Project claim 1.
(4) the supervision organization shall issue change instructions to the contractor according to the authorization of the supervision contract and the provisions of the construction contract.
(5) the measurement and pricing method or measurement results of the changed project.
Change handling procedures: the supervision unit issues “change instructions”.
(6) the increase or decrease of the contract investment of the changed project (7) Analysis of the impact of the changed project on the contract duration 7.
The “review opinions on engineering change price” must include independent review opinions on the unit price (or price) of the changed project, the measurement and pricing method of the changed project, and the unit price analysis results of the supervisor if necessary.
Claim is a normal phenomenon that often occurs in project contracting..
Major design change refers to the impact on the construction period, safety, investment, construction cost, construction cost, etc.
When the employer and the contractor cannot reach an agreement on the change price, the supervision organization shall carefully study and carefully determine the appropriate provisional price and notify the parties to the contract for implementation; when the employer and the contractor cannot reach an agreement on the construction period, Handle as agreed in the contract.
Definition project claim refers to the request for economic compensation and / or time compensation from the other party for the actual losses caused by the other party’s responsibility rather than his own fault during the performance of the contract.
(3) After receiving the Contractor’s change proposal, the supervision organization shall review it according to the following contents; if the supervision organization agrees to the change, it shall report to the employer for approval and issue the change instruction.
(7) When the employer and the contractor reach an agreement on the change price and construction period, the supervision organization shall witness the parties to the contract sign the change item confirmation form.
