Addendums can severely impact the scope of a project prior to the bid. It is very important to check frequently if an addendum has been issued for a project you are estimating. Even if you are on the plan holder list, an estimator can’t rely on others to notify them of the changes. Whether you call the Architect to verify or subscribe to publications that show addendums the estimator is responsible for ensuring they have received all the addendums.
The market is hard enough these days, there is no use making it more difficult on yourself by making it possible for your bid to be rejected because you didn’t incorporate an addendum into your bid.
By the way, a subcontractor should always include a scope letter with every bid. The scope letter needs to state which addendums they have seen even if it didn’t pertain to their scope of work. If by some miracle, there was no addendums issued, the scope letter should state that no addendums were received.
