What We Do

Foundation Design & Framing Systems

We design foundations tailored to your site's soil conditions, including shallow foundations, deep foundations, post-tension slabs, and grade beams. Our designs account for soil bearing capacity, settlement, and seismic forces to ensure long-term stability.

We engineer efficient framing systems for floors, walls, and roofs using wood, steel, concrete, or hybrid construction methods. Our designs optimize material usage while meeting all strength and deflection requirements.

Engineering Analysis

Load Calculations & Connection Design

We calculate all applicable loads including dead loads, live loads, wind loads, seismic loads, and snow loads. These calculations form the basis for safe, code-compliant structural design.

We provide complete structural calculations and engineer's reports that demonstrate code compliance. These documents are required for permit submittal and building department review.

We detail all structural connections including beam-to-column connections, foundation anchors, shear wall hold-downs, and specialty connections. Proper connection design is critical for structural integrity.

Why It Matters

Importance of Structural Integrity

During any residential or commercial construction project, ensuring the proper strength, stability, and rigidity of a structure is of the utmost importance. Structural engineering provides:

Safety

Protects occupants from structural failure, collapse, and earthquake damage.

Code Compliance

Ensures projects meet California Building Code and local requirements.

Longevity

Designs structures to withstand loads and environmental conditions for decades.

Value Protection

Prevents costly failures and maintains property value over time.

Insurance & Liability

Provides necessary documentation for insurance and reduces liability exposure.
