Happi, be carefull as others have said, and in addition to that, never figure a demoed building is like new construction.
As far as estimating the project, you must have a complete scope of the work, specs, drawings, and special systems. Otherwise you are only coming up with a budget number. Make this clear to whoever is asking for you to speculate the project.
Take exception to any unclear items if you can not get answers before bid time. This doesn't relieve you of your responsibility of all contract documents, but will red flag items that you might need to ask for a change order for.
One bad job takes a long time to recover from.
