Looking for input on working with my architect
I am in Arizona, US. I'm currently working with a smaller architectural firm (maybe 5 designers) to come up with plans for remodeling my 1970's ranch style home to add a second story (~1300sqft) and a smaller main floor addition (~300sqft). I'm not a professional builder by any means, but have done major remodels on 5 homes as well as an owner/builder on a 1200sqft new construction personal home.
I started the engagement with them at the end of December and they sent someone out the first week of January to take measurements of the existing house so that they could draw up an as-built plan and begin the work. We went back and forth to work out the floor plan through March and the experience was overall decent with my only complaint being that it would usually take a week to get a response back from them. At the end of March we were settled with the floorplan and design and they were going to send it off to a structural engineer to size any foundation changes and beams for the second floor, we were told at that point that we should be able to submit for a permit by the end of April.
I reached back out mid April to double check that we are still on schedule, and apparently the engineer had been on an extended vacation and wasn't even going to look at it until the following week. Okay, sure. We finally got a complete set of plans back at the end of April to review before submitting to the city for permitting.
Upon reviewing the plans, I realized that they had drawn up all of my interior walls as 2x6 instead of the 2x4 that they actually are and were expecting 6x6 posts in several of these walls to hold up the floor system above. I sent them some detailed notes about this and we are working through it.
Due to a lack of overall dimensions listed on any of the floorplans that we approved, I also didn't realize until this final review set that they mis-measured the existing house. Being off 3-4" on most of the interior measurements on the existing first floor, while annoying, can likely be worked around. They were, however, short by 2' 7" in the overall structure in one dimension...
I got a copy of the as-built plan from them (after some delay) and went through the major measurements and the interiors under where the second floor will be. I updated the dimensions listed and sent them back over. They're now reviewing it.
TLDR: after working with an architect for 5 months on a total 1500sqft addition (mostly second story) I realized that they mis-measured my existing house by 2' 7" in one dimension and 4" in the other.
Am I crazy for thinking this should be going much smoother than it has been? Is there anything you would suggest that I could do from my side to help the process along? I'm at a bit of a loss at this point and the amount of faith I have in my architect is dropping by the day.
