Special Bidding Instructions – Effective 4/29/2020

Starting on April 29, 2020, CDB will resume accepting bids for construction projects.  CDB and the CPO Office have jointly developed Special Bidding Instructions that will be in effect for the duration of the COVID-19 Emergency.  These new instructions will allow CDB to once again fulfill a critical part of our mission for the State of Illinois.  While the Special Bidding Instructions posted on the Bid Information page of this website should be read carefully and completely, major changes include:

Bids will only be accepted via mail and email.  No in-person submittals of bids will be allowed.

To help expedite the bid opening process, please place the completed 4100 form first in your uploaded bid packet.

Bids will only be accepted at the CDB Springfield Office.  No bids will be accepted at the CDB Chicago Office or the CDB Carbondale office.  Bids sent to other CDB offices will not be forwarded and will be considered disqualified.

Bids will be standardized to have submittals due on Wednesdays at 5:30 pm, and to have a virtual Bid Opening occur on the following Friday at 10:00 am via WebEx. These virtual Bid Openings will be open to the public.
