I don't believe that will be necessary.
Check your Department of Epic Projects first for an icon or bubble on or above and click on it. If it gives you a tutorial on how to use Speed Up Tokens, follow it. Drag any Token into any of your Commercial Buildings. Next, check all of your other Government Buildings except City Hall (where you collect taxes) and see if there are are any other icons or bubbles on or above those buildings with tutorials for you to follow. If there are, follow them. If you do have at least one Regular or Standard Residential Building and City Specialization to support it, a gold, winged helmet should appear on the building. Click on the winged helmet and you can begin your Epic Project.
*You may want to check and make sure that all commercial buildings available to you are placed.
If this does not work, please share a screenshot.
@oldiepants You may want to see if there are any tutorials you've missed as well. Personally, I would check all Regions too, and War, and Monster, and Vu Tower, and Tasks on buildings at this point, for any tutorials...Speaking of Tasks on Buildings, if you have a clipboard or clipboards on your only Regular/Standard Residential Building(s) you will not get a gold, winged helmet or be able to complete any Epic Projects on those buildings until after the task has been fully completed. Either complete the task entirely on one of them or build a new Regular/Standard Residential from the ground up.
Good luck to both of you!
