AHPP errors in project delivery chart?
From the Architect's Handbook of Professional Practice: this chart (figure 9.3 on page 516 of the 15th edition) appears to have some errors and so now I'm doubting the reliability of the whole thing. For example, under cost plus fixed fee, I don't believe the constructor contract is determined so early (I have notes from another source that say at end of CDs), and it is missing the cost of construction time. BN from the legend at the bottom is not used - I assume it should replace PR in the chart. When is the construction contract established under the different CM delivery types? Can anyone at least verify the correct time for contracts and pricing for cost plus fixed fee? Do you see any other errors or important missing information?

I would think the $ (Cost Of Construction) is both during the course of construction and the final cost at the end of construction, after substantial completion and final completion. Cost + Fixed Fee is basically a project with too many unknowns therefore you can’t determine what the final cost will be until everything is complete. The contractors fee is his fee but the scope is unknown. With regards to when the Contractor is brought on board, I Assumed it’s after BN. I don’t understand the reasoning to why it’s after SD. If it’s after SD then that to me implies that it is a cousin of the Negotiated Select Team with the one difference that Scope is yet unknown. Scope yet unknown ie. Adaptive Reuse.

See Amber Book's chart for comparison. It's a bit more thorough, and combines the driving factor info from a separate AHPP chart.
I hope Michael/Amber Book does not mind me posting this (he displays this in one of his free 40 Minutes of Competence videos on YouTube). It's not available only to his paid subscribers, but I'll remove it if it's an issue.
