Services

Structural Engineering for the Projects You Actually Build.

From a single beam to a complete structural set, every service runs through the same workflow: submit what you have, receive a defined scope and quote, and track the project through engineering, licensed engineer review and final documents.

Structural Plans & Calculations

Foundation and framing plans, lateral design, details and a bound calculation package — engineer reviewed and organized the way building departments expect to read them.

  • New single-family homes and custom residences
  • Duplexes, triplexes and small multi-unit buildings
  • Whole-house remodels with extensive structural changes

Remodels & Load-Bearing Wall Removal

Beam, post and footing design with a complete load path — engineered from your plans or photos and delivered as permit-ready documents.

  • Kitchen-to-living-room wall removal
  • Flush beams for uninterrupted ceilings
  • Enlarged window and slider openings
View service

Room & Second-Story Additions

Foundation, framing and lateral design for room additions, second stories and bump-outs — coordinated with your architectural set and the existing structure.

  • Single-story rear and side additions
  • Second-story additions over the existing footprint
  • Bonus rooms over garages

ADU Structural Engineering

Complete structural packages for detached ADUs, garage conversions and units over garages — sized for California's ADU review process.

  • Detached new-construction ADUs, studio to three bedrooms
  • Garage conversions with door-opening infill
  • Attached ADUs sharing a wall with the main house
View service

Foundation Engineering & Repair

New foundations, underpinning, seismic retrofits and repair details — engineered from your plans, photos and inspection reports.

  • New foundations for additions, ADUs and new homes
  • Foundation replacement under existing homes
  • Underpinning and settlement repair

Retaining Wall Engineering

Cantilevered concrete, CMU and segmental walls engineered for the actual soil, surcharge and drainage conditions on your site.

  • Cantilevered concrete retaining walls, 4 to 12 feet
  • Reinforced CMU retaining walls
  • Segmental block walls with geogrid reinforcement
View service

Commercial Structural Engineering

Rooftop equipment, storefront openings, mezzanines, racking and structural modifications — engineered to the California Building Code on a schedule your lease can live with.

  • Tenant improvements with new openings or interior framing
  • Rooftop HVAC and mechanical equipment support
  • Storefront and loading-dock openings in CMU or tilt-up walls
View service

Permit Corrections & Plan-Check Responses

Structural responses to correction letters — revised sheets, supplemental calculations and a response matrix that walks the reviewer through every comment.

  • Structural comments on residential remodels and additions
  • Missing or incomplete lateral analysis
  • Requests for calculations to support beam and header sizes

How it works

From Plans to Engineering in Four Steps

  1. 1

    Submit Your Project

    Tell us what you're building and upload whatever you already have. Plans, photos, sketches and permit comments can all be submitted.

  2. 2

    Receive Your Scope & Quote

    We review the project and send you a defined engineering scope, price and estimated turnaround.

  3. 3

    Engineering Begins

    Your project moves through structural design, calculations, drafting and engineer review.

  4. 4

    Receive Your Documents

    Final engineering documents are delivered through your project dashboard. Permit comments can be submitted back through the same project.
