Trusted by builders and homeowners.
“The calculations were clear enough that plan-check approved on the first submittal. No back-and-forth, no delays.”
“They walked us through the retrofit options in plain language and stood behind the numbers. The whole job felt handled.”
“We removed two bearing walls for an open kitchen. The beam sizing was exact and the framing crew had everything they needed.”
“Coordinated directly with our architect and turned the structural set around fast. Drawings were clean and buildable.”
“Foundation report for a hillside lot that other engineers wouldn't touch. Detailed, defensible, approved by the city.”
“Stamped our SB721 balcony inspection on schedule and flagged a repair we hadn't budgeted for. Saved us a much bigger bill later.”
