The math behind the buildings you trust.

Principal Engineer
The Bench
Specialists,
not generalists.
Every project at Girder is staffed by an engineer whose deepest expertise matches your building's critical challenge — not the next available body.
Long-Span Bridges & Lateral Systems
Diane Okonkwo, P.E., S.E.
Senior Structural Engineer
Sixteen years designing river crossings and pedestrian bridges across the Northeast. Diane reads a load diagram the way a conductor reads a score — she hears where the stress concentrates before the model runs.
Signature Project
Millbrook River Crossing
Vehicular Bridge · 340 ft span
Post-tensioned concrete girder bridge over active waterway. Designed to carry H-25 loading while meeting AASHTO fatigue requirements at a constrained urban site.
Seismic Analysis & Hospital Structures
Rafael Suárez, P.E.
Associate Principal
Rafael spent five years with a research team at UC Berkeley's Pacific Earthquake Engineering Research Center before entering practice. He applies that rigor to every hospital, data center, and essential facility that cannot afford downtime.
Signature Project
Eastview Regional Medical Center
Hospital Expansion · 6-story · 280,000 SF
Full lateral-force resisting system design using special moment frames and buckling-restrained braces. Peer-reviewed to ASCE 7-22 with nonlinear response history analysis.
Forensic Investigation & Adaptive Reuse
Priya Nair, P.E.
Senior Engineer — Forensics & Retrofit
Priya has investigated over 140 structural failures and distress conditions — from warehouse roof collapses to post-fire concrete assessments. She knows what buildings hide and how to make them honest again.
Signature Project
Garment District Loft Conversion
Forensic + Retrofit · 1924 mill building · 8 stories
Full forensic investigation of deteriorated cast-iron columns and unreinforced masonry bearing walls. Designed a concealed steel moment frame within the historic envelope to achieve current code compliance without altering the facade.

First Response SLA
New Construction
Complete structural systems from concept through permit — gravity framing, lateral systems, foundation design, and construction administration.
Seismic & Lateral
ASCE 7 compliance, nonlinear response history analysis, and performance-based design for essential facilities and high-seismic zones.
Forensic Investigation
Distress assessment, failure investigation, and expert reporting for litigation support, insurance claims, and remediation design.
Peer Review
Independent third-party review of structural calculations and drawings for municipalities, developers, and design-build teams.
Retrofit & Adaptive Reuse
Structural upgrades to historic and existing buildings — preserving envelope character while meeting current code requirements.
Value Engineering
Targeted redesign under deadline to reduce structural cost without compromising safety factors or long-term performance.
