/ 01 SERVICES

Three practice areas. One engineering team.

We staff every project with a registered PE on lead, a project engineer in coordination, and a BIM lead handling clash detection through DD. Same team start to finish.

High-rise & mixed-use

Composite steel and reinforced concrete towers, 8–42 stories. Wind tunnel coordination, lateral system optimization, and post-tensioned floor plates for tight floor-to-floor heights.

Tallest delivered

38 stories

Healthcare & lab

OSHPD-style vibration-controlled framing for imaging suites and wet labs. Seismic detailing per IBC 2024 with redundant lateral systems and operational continuity targets.

Vibration spec

VC-A typ.

Transit & infrastructure

Stations, platforms, pedestrian bridges, and parking structures. AASHTO LRFD compliance, fatigue analysis on bracing systems, and accelerated construction techniques for live-track environments.

Design code

AASHTO LRFD 9th
