I do not know if you are talking about the original Architect of record or the new one and I certainly know absolutely nothing about the drawings BUT from what you describe (and I have no idea if what you are saying is correct or not), there was not sufficient time allocated to coordination which is poor work on the part of the Architect - but this does not change the premise of my argument - a good client pays for good drawings - a good architect produces complete and accurate and well coordinated sections/elevations and details AND a good builder executes these per the drawings. In fact a competent Builder would easily spot the discrepancies in drawings and should bring it to Architect's attention way before Construction starts (this does not mean Architect has license to be sloppy).
An architect LEGALLY cannot tell a Builder and certainly cannot tell any of the GC's subs what to do on site or how to build something - they can bring discrepancies and deviations from the drawings to the Owner's attention and ask that Owner act accordingly and notifies Builder. An Architect is paid to observe (some call it administer) Construction BUT they have to trust that details are being executed properly (IF they have been correctly drawn).
You are probably pretty good at your profession and may perform administered work differently than the original Architect of Record on the job this Thread is about. The administered contract on this job was very different from anything that you have described. In this case the Architect was the designer, the co-ordinator of all professions and the inspector of the work. It was an AIA contract. The Architect of Record had their own licensed builder in house as their inspector and a retired engineer as additional eyes.
This Architect would create drawings with page inconsistencies, the builder of record would bring the discrepencies to the Architect via RFI's and the Architect would then charge the Owner for re-design.
I've seen a bunch of Architects put blame to a builder for their own error or ommission, that goes both ways, it's when a design professional knows the facts and shifts responsibility that they cross the line.
