All ITBs and RFPs are due in the Purchasing Department, 122 Waddell Street NE, Marietta, GA 30060 before 12:00 pm Eastern Standard Time on the date specified in the bid or proposal document.

Interested bidders may click on the underlined bid number to view the advertisement and specifications of the solicitation. Solicitations on this website are available in PDF format only. Adobe Acrobat must be installed on the computer being used to view bid documents.

The Purchasing Department will take reasonable steps to ensure that known perspective bidders have all applicable addenda. However, it is the ultimate responsibility of the bidder/proposer to ensure that they have all applicable addenda prior to bid/proposal submission. Failure to submit all addenda with the ITB/RFP may be cause for the submission to be rejected.

Any addendum issued for a solicitation will be posted under the bid number and labeled accordingly (Addendum 1, Addendum 2, etc.).

In some instances, ITBs/RFPs must be obtained directly from the Architect or Engineer.
