Inquiry #9: Regarding Inquiry #3:
Does the department anticipate pushing this job to bid after the holiday? The current bid date will make the post-bid paperwork due right after the December 26th Christmas holiday. Firms will likely be short –staffed and possibly even closed for the holiday week, making it difficult to obtain written DBE confirmations. Please consider a bid date change giving contractors the proper amount of time to submit responsive post-bid paperwork.
