What is an Addendum in construction documentation?

An addendum in construction documentation serves as an official modification or clarification to the bidding documents before they are finalized and the contract is awarded. It may be issued to provide additional information, clarification of the project's scope, or to amend any parts of the existing bidding documents. Including this instrument ensures that all contractors have the same information and can bid on a level playing field, minimizing ambiguity or misunderstandings that could arise during the bidding phase.

The role of an addendum is crucial because it directly affects how bidders perceive the project. If any changes or nuances must be communicated, such as adjustments to specifications or timelines, they are documented in the addendum, making it an essential part of the pre-contract documentation process.

Considering other options, a document outlining the project ownership structure doesn't relate to the immediate adjustments in the bidding process. A revision made after project completion would imply a level of finality and is typically addressed through change orders instead of addendums. Lastly, a summary of project specifications does not encompass the dynamic and clarifying nature of an addendum, which is specific to adjustments made during the bidding period.
