In this special partner episode, Jack Sadler joins the podcast to talk about the phase of a project where architects quietly lose control: construction administration. We explore why CA became a cost center instead of a profit center, what happens when architects run their work out of someone else's software, and how AI can automate the routing, logging, and paperwork without ever touching the professional judgment that actually matters. Jack makes the case that CA is where design intent gets realized or negotiated away, and that owning the flow of information is how you make sure it's the former.
This episode is especially relevant for firm leaders, project architects, and anyone who's been handed the CA phase and felt it turn into email triage, spreadsheet chasing, and cover-your-ass paperwork. If you've ever suspected there's a better way to run construction administration, one that makes your firm smarter, more defensible, and maybe even profitable, this conversation will give you a concrete place to start: take back control of what you're already accountable for.

About Jack Sadler:
Jack Sadler is the co-founder and CEO of Part3, a construction administration platform built specifically for architects and design teams. He's not an architect, and he'll tell you so up front. His background is in technology, with years spent in vertical SaaS across healthcare, finance, and travel, and a long stretch doing custom software, the kind of zero-to-one work where you get dropped into a new business model and build something from scratch. Before Part3 he held product leadership roles at companies like Rangle.io and CrowdRiff.
The construction angle came from home. His wife went to school for architectural science and spent six or seven years on site for a general contractor before moving to an architecture firm, where she went from a world of purpose-built tools to running everything out of spreadsheets and email. That gap became the company. Part3 is a bet most investors told Jack not to make, that you can't build a business serving architects, and a bet he's glad he ignored. That outsider's view of how design teams actually work during CA is exactly what makes him worth listening to here.
