There is no gravel in the original design, and the reason for the change is written after the actual

Don't make your own decisions, it's who proposes it, find a design and make a design change. If it has nothing to do with the structure, you can also negotiate with Party A, and finally sign the design. No matter what this process is, he will find the supervisor to sign, and he will prove that he has gone through the formalities.

Report the discrepancies to the construction unit and the design unit, and submit an application for design change. From the date of approval of the preliminary design to the date of formal delivery through the completion acceptance, the project shall modify, improve and optimize the approved preliminary design documents, technical design documents or construction drawing design documents. Design changes should be issued in the form of drawings or design change orders.

Changing the timing and sequence of construction of the works in question is a design change. The report of the change in the price of the works shall be submitted by the contractor. If the contractor changes the construction organization design during the construction process, it shall be agreed by the owner and the supervisor.

Design changes are chaotic in the field. Complex and chaotic management of design changes to the construction site has brought great inconvenience, the construction of the first part of the version has been changed repeatedly, the number of design change modification notices is too much, the construction site is not even clear which version of the drawings is really used for the construction of the drawings.

Design changes and technical approval orders are confused. The construction unit often asks for changes for various reasons in the construction, and the on-site representative of the construction unit cannot correctly analyze and judge, and is credulous or verbally agrees first, resulting in a fait accompli. Supervision and design do not fulfill their duties, and the technical approval of the project is approved and signed, and there are more cases of supplementary signing and change after the fact.

Add some details that will be used as a basis for your future visa:

1. Party A's modification opinions may be approved layer by layer and cannot follow up the on-site progress in time, and the site may be implicated in other construction projects that cannot be carried out as planned due to the inability to determine the plan, so the problems implicated should be explained in the contact form.

2. Set a time to require Party A to provide a modified plan. If Party A fails to provide a plan by the time, it cannot be relaxed at this time, and must send a contact sheet with the same content to continue to urge Party A, emphasizing that the problem is not solved and the construction party is in a passive state, how to brag about it. There is a reason why this kind of procedure is done comprehensively and comprehensively.

3. Take a photo for the card.

First of all, write the project contact sheet and send it to the construction unit (Party A) and the supervision unit. It is necessary to write clearly which drawings and what parts do not conform to the site, or the situation that cannot be constructed.

Party A receives the project contact form and will contact the person from the design unit to hold a meeting to discuss the change. If a change conclusion is reached, the construction unit (Party A) should issue a change notice to the construction unit and the supervision unit.

The construction unit can follow the change order to carry out the construction. (Note: Some of the problems involving **, but also to write the cost of the change also need to be reported to Party A's visa).

Whether it is the reason of the construction unit, or the reason of the design or construction unit, the engineering quantity that does not conform to the drawings must be calculated. The actual engineering quantity is inconsistent with the engineering quantity of the drawings, and it is generally handled according to the following situations: it is calculated according to the design change and design documents, and the engineering quantity without design change is not calculated.

It is calculated according to the quantity visa. For example, earthwork is calculated according to the actual quantity of the project measured on site, and the calculation according to the drawings is not accurate. It shall be handled in accordance with the valuation range of the change in the quantity agreed in the contract.

For example, when some contracts stipulate that the project cost exceeds or is less than 5% of the total contract price, the changed project quantity will be priced, and the difference between the project cost and the total contract price will not be adjusted. It depends on how the contract is determined.

The design quantity cannot be zeroed, and the design quantity and workload can only be increased or decreased by design changes.

Secondly, list the basis of the results and judge whether the basis for treatment is appropriate.

Finally, to sum up, to apply for a change or visa outside the design (a visa can be obtained due to reasons not caused by the construction party), the design and supervision require a visa.

If it is your own construction reason, you can only bear it in full.

Technical approval orders are used to modify the design. There is a ready-made technical approval form, which can be filled in.

Name of the unit project: fill in according to the truth.

Propose to modify the unit: fill in according to the truth.

Amendments: Decoration design of architectural design.

Original design: 20 thick floor tiles.

Reason for revision: There is no stone with a thickness of 20 on the market.

Changed to: stone thickness changed to 18mm.

Approver: (Signed).

Approval Engineer: (Signed).

Approval unit: (signature and seal).

Approved Date: YYYYYYYYYYYYYYYYYYYYYYYYY

Approval unit: (signed).

Delivery unit: (sign) (construction unit, construction unit,).

As we all know, after the cross-section of the engineering pile is determined, its final bearing capacity changes with the changes of geological soil quality, layered thickness, and physical and mechanical indicators (such as soil friction around the pile and soil bearing capacity at the end of the pile).

When the geological conditions of the bored pile construction are inconsistent with the geological exploration report (such as the lack of soil layer, the difference in the thickness of the soil layer, etc.), the construction or supervision unit should generally be notified in time. Organized by the construction unit, together with the relevant engineering and technical personnel of the exploration, design, construction and supervision units, the relevant engineering and technical personnel of the exploration, design, construction and supervision units will go to the site to re-test the pile (or supplementary exploration) for verification and sign for confirmation, and the design unit shall conduct design review or design changes according to the new geological exploration data.

Within 14 days after the construction contractor receives the design change document, according to the scope of work involved in the design change document, the quantity of the project and the relevant change price adjustment provisions agreed in the construction contract, submit the application for confirmation of the change visa and the adjustment of the valuation document to the supervision construction unit. If the supervisor has any objection to the application for change of valuation, the contractor shall be notified to revise and resubmit. The construction unit shall complete the examination and approval within 14 days.

If the construction unit fails to complete the examination and approval within the time limit or does not raise an objection, it shall be deemed to have approved the change application (visa) submitted by the construction contractor.

If the geological exploration report of the bored pile is inconsistent with the actual situation of the construction site, the survey unit, the supervision unit, the owner, and the design unit should be invited to confirm the situation, and the design unit will issue a design change.

The most important thing is that you have to ask the geological survey unit to confirm that the rock sample is indeed inconsistent with the report, and then apply.

The main responsibility is the responsibility of your construction unit, if the construction unit requires the change, you also have to go through the change procedures, when you change the change, you have not been recognized by the design unit, even if the design unit agrees verbally, you have no procedures. As for the fact that there is no legal basis for you to let the design give you a blueprint again, the design will give you better, and it is also your duty not to give you a blueprint; After the blueprint is released, it is another matter whether the construction unit approves it, and it is even more difficult to say as the basis for settlement. You still have a lot of work to do.

Of course, this must be changed, otherwise the construction cost is different, and what should be done about the loss of the construction party?

Oh friends, the cost of excavation varies greatly, and the cost of excavation is even higher if it is a harder rock.
