What would be the recommended time/phase during a New Construction project when one should submit the preliminary design review? I have read in some of the comments that it is done before construction starts, after construction documents are completed. Is it recommended to wait for that long, I am concerned that if things have to be changed as per review comments, it will have to be done after the drawings are already out. Is it then better to submit while CD phase is going on? What are the drawbacks in doing an earlier submission? We would like to attempt at submitting all the prerequisites and the design credits for the preliminary design review.
