CHOP is silent about extending the bid period except for stating
that if an external event such as a snow storm prevents the majority of
bidders from submitting bids, the closing may be postponed.
Natural disasters rank low on the list of reasons for the majority
of bid period extensions. Often the reasons given by contractors include
complexities unanticipated by the bid caller, too many bids closing
around the same time, and addenda issued late in the bid period. The bid
calling authority may also choose to extend the bid period at the time
is issuing a large or complex addendum.
The length of any extension is a judgement call based on the nature
of the changes incorporated in the addendum. The new closing date
should consider the same guidelines used to select the original closing
date (not Mondays or Fridays or immediately before or after statutory
holidays).
Along with changing the bid closing date, changing the project
start date or the substantial performance date should be discussed with
the client.
