"The cantilever calcs came back in 18 hours."The stamp was on the drawings before my client even asked if we'd heard back. That's the kind of firm you want on the project team.

"The bank released the draw on schedule."We needed stamped calculations before the bank would release the construction draw. Girder had the package to our lender in under 24 hours. The draw closed on schedule.

"The engineer called me back in four minutes."Six a.m. on the slab, the concrete truck is idling, and I've got a question about the pour sequence. I texted the number on the drawings.
