Turnaround was actually faster than promised. Plan check passed first submittal.
Clear calcs, clean drawings. The plan checker had zero comments on the structural sheets.
Way better than the last freelancer I hired. Actually knew our jurisdiction.
Fixed price stuck. No surprise "revision fees" like other places.
Responsive, professional. Answered contractor RFIs during construction.
Solid work. One minor coordination issue with the architect but resolved same-day.
Great value. Would use again for the next addition.
They pushed back on a bad detail from the architect and were right. Saved rework.
Legit engineer, not a subcontracted overseas shop. Big difference.
Delivered on time. Calcs were easy to read. Framer had no questions.
Fair pricing and no BS. Highly recommend.
Good work. Turnaround stretched by two days because of a holiday but they communicated.
