If they call you it means they are checking city or county records for approved building projects and are fishing to get the job. obviously based on what you said if someone posted building plans for bids they would know why the company was calling and would not be posting here. AVOID companies like this as they are rarely local and will resell your job to another contractor at a profit without lifting a hand, which in the final analysis means you paid too much. AVOID.
These people call here on a regular basis wanting to know the bid schedule. I have no idea what they are talking about. Left her name and Bid Clerks # 312-423-3900 but she called from ConstructWorks 312-380-4821.
I think they are selling something and it's really fishy!
No, it's not fishy. Somehow you got on a bid list for construction. It's a company contractors subscribe to and get leads from for "their" fee. Your number may nave been mistaken for someone elses.
