The answer to this question varies from project to project and is based on the scope of work for the project. Asking an architect to complete a project in too short of time often results in errors and problems in the field which are typically very costly to correct.
To illustrate this I am posting a link to a sketch of a 1-minute challenge to draw a picture of Spiderman. This graphic accurately captures what can happen to a project when a deadline gets moved up or is too short, to begin with.
I hope you enjoy the short video and I look forward to hearing from you and answering more questions as they come in.
