About me

PlanSwift and Bluebeam are part of my daily workflow, and every deliverable is built to hold up at the bid table — any trade, any state. When I'm not estimating, I'm probably losing a soccer match. ... Read more

    Worked with Jack (JW Estimating) on a commercial bid and honestly the level of detail was next level. I've done estimates myself for a while now, and there was so much in-depth work happening that I didn't even realize was doable — line items, breakdowns, ways of catching scope I would've missed on my...
