What responsibility does the architect/engineer maintain when the addendum is used?

The role of the architect or engineer in relation to an addendum is fundamentally tied to the design of the project. An addendum is a document that modifies the original contract documents before they are finalized and put into action. It may include clarifications, updates to specifications, or adjustments to drawings. Since these changes directly relate to the design and specifications of the project, the architect or engineer retains the responsibility to ensure that all modifications maintain design integrity and meet the required standards.

This responsibility includes addressing any questions or concerns that arise from these changes and ensuring that the project aligns with the overall design vision. Therefore, retaining responsibility for the design ensures that the modifications provided in the addendum contribute positively to the project’s architecture and engineering goals.
