What does the term 'addendum' refer to in construction documents?

In construction documents, the term 'addendum' specifically refers to a document that provides additional information or clarifications related to the original contract documents or project specifications. Addenda are issued to address questions raised during the bidding process, clarify ambiguities, or provide further details that may be necessary for contractors to adequately prepare their bids.

This is essential in ensuring that all bidders have access to the same information and understand the requirements before submitting proposals. The purpose of an addendum is to make sure that everyone involved in the construction project is operating with the same set of updated facts, promoting transparency and fairness during the bidding and construction processes.

In this context, the other options do not accurately capture the essence of an addendum. A revision to project scope typically refers to adjustments made to the overall goals or objectives of a project rather than additional clarifying details. A formal request for changes is more commonly referred to as a change order, which is different from an addendum in terms of its function and timing within the project lifecycle. A summary of completed tasks is not related to the concept of addenda, as it pertains more to project management and tracking progress rather than additional information provided to improve understanding of project documents.
