I would like to share a discussion with you.
On the basis of the contract between the Design company and Client, the detail project was executed, the project was agreed with necessary government agencies, and a set of project-estimate documents was handed over by the Design company to Client.
The completion of the construction of the project is delayed due to the delay in the delivery of some of the equipment in the project. However, there is a need to start the system in production. The Client tries to make the system work temporarily by making some changes in the project. Note that the change in the project is temporary. After the equipment in the project was received, the temporary changes will be replaced with the equipment which are in the main project and the construction of the facility will be completed according to the designer's project.
At this stage (after the Design company has finished its mission, that is, after it has fully handed over the detail design documents of the project to the Client according to the contract):
1. Is the Design company responsible or liable for the Temporary changes made by the Client in the construction of the project?
2. Is the MOC document prepared at this stage?
3. If a MOC document is prepared, should the Design company has a signature on this document?
4. If the contract between the Design company and the Client is only for the detail design documentations , is the Design company's signature on this Temporary change document considered valid?
5. Or should the Temporary change to the project be performed on the basis of the contract signed between the Design company and the Client?
6. Or does the Client have fully authority to make changes in the construction of the project (without the Design company 's signature)?
It would help me a lot to know your opinion.
