What function do "Addenda" serve in construction documentation?

Addenda serve a critical function in construction documentation by providing additional information or changes to the project specifications or drawings prior to the bid submission date. This is essential for ensuring that all potential bidders have access to the same updated information, which promotes equity and clarity in the bidding process.

By issuing addenda, the project owner or architect can clarify ambiguities or make adjustments based on feedback received during the bidding period, thereby helping to align expectations and avoid misunderstandings regarding the project requirements. This process is vital for creating accurate and competitive bids, especially as it allows contractors to incorporate the most current requirements into their proposals.

In contrast, the other options do not accurately reflect the purpose of addenda. Final interpretations of the contract occur after bids are received and contracts have been executed. Summarizing site inspections relates more to project management during construction than to the bidding phase. Closing a project formally would involve documentation such as final reports, not addenda. Thus, the role of addenda is specifically tied to modifications and clarifications made before bids are submitted.
