Structural engineering
you can build on.
Safe, efficient, code-compliant structural design — coordinated with architecture and construction so nothing gets lost between disciplines.
Overview
Structures engineered for safety, value, and constructability.
Our structural engineering ensures your project stands strong and meets every code requirement, while staying efficient to build. We design foundations, framing, and lateral systems suited to your site and soil.
Because engineering happens alongside architecture and construction, we catch conflicts early — reducing change orders, delays, and surprises once the build begins.
What's Included
Engineering that holds everything together.
Foundation Design
Footings, slabs, caissons, and grade beams matched to your soils report.
Framing & Load Paths
Efficient wood, steel, and concrete framing systems.
Lateral & Seismic Systems
Code-compliant design for California seismic requirements.
Calculations & Permit Support
Stamped calculations and plan-check coordination.
Why ATP
One accountable team,
start to finish.
Build on a solid foundation.
From a single addition to a full ground-up build, our engineering keeps your project safe and on schedule.
