If you own a soft-story apartment building in Burbank, you've likely received notices about mandatory seismic upgrades. But what does a structural engineer soft story specialist actually do beyond signing off on plans? The answer involves far more than most property owners realize—from detailed engineering analysis to serving as the engineer of record throughout construction. Understanding this role is critical to ensuring your retrofit project meets compliance requirements and genuinely protects your building.
What Is a Soft-Story Building?
Soft-story structures—typically multi-family residential complexes built before modern seismic codes—have a weak or flexible first floor, often featuring parking spaces or large openings. During an earthquake, these vulnerable ground floors can collapse, leading to catastrophic structural failure. Burbank's mandatory retrofit ordinance requires property owners to strengthen these buildings, with strict deadlines and penalties for non-compliance.
The Structural Engineer's Role in Soft-Story Retrofits
A soft story structural engineering project involves multiple phases, each requiring specialized expertise:
1. Initial Structural Assessment
The process begins with comprehensive evaluation of your building's existing conditions. The structural engineer will:
- Conduct thorough on-site inspection to assess the building's structural system, foundation type, lateral force-resisting elements, and existing damage.
- Review original construction drawings and perform measurements to verify existing conditions, including column sizes, wall locations, and foundation details.
- Evaluate soil conditions and geotechnical reports to understand seismic response requirements.
This Burbank structural assessment phase is critical because every building is unique—engineers must tailor their approach based on specific structural systems and site conditions.
2. Seismic Analysis and Engineering Calculations
The structural engineer performs detailed soft story engineering analysis using advanced modeling software. This phase includes:
- Creating computer models to simulate building behavior during earthquakes, accounting for ground motion, building mass, and structural stiffness.
- Performing Burbank seismic design calculations in accordance with California Building Code, ASCE 7 provisions, and Burbank's specific ordinance requirements.
- Determining required strength of new structural elements—steel moment frames, shear walls, or bracing—to resist seismic forces and prevent collapse.
This rigorous analysis ensures the retrofit design will actually protect your building during major seismic events.
3. Designing the Retrofit System
Based on engineering analysis, the structural engineer designs a customized retrofit system. Common solutions include steel moment frames, plywood or steel shear walls, foundation upgrades, and connection improvements. A skilled Burbank retrofit plans engineer of record knows how to design effective, code-compliant solutions that minimize disruption and cost.
4. Preparing Construction Documents
The engineer prepares detailed construction drawings and specifications including structural plans, foundation plans, construction details, and calculation packages demonstrating code compliance. These documents must be stamped by a licensed California engineer—they cannot be prepared by contractors.
5. Serving as Engineer of Record During Construction
As the Burbank retrofit plans engineer of record, the engineer remains involved throughout construction, reviewing contractor submittals, conducting site visits, responding to RFIs, and coordinating with city inspectors. This ongoing oversight ensures the work matches approved design and maintains structural integrity.

Soft-Story Retrofit Engineering – Frequently Asked Questions (FAQs)
Q) What's the difference between a retrofit engineer and a contractor?
The Burbank retrofit engineer vs contractor distinction is critical. The structural engineer designs the retrofit system, performs calculations, prepares permit drawings, and serves as engineer of record. The contractor builds what the engineer designed. Only a licensed engineer can legally perform engineering design and analysis.
Q) How long does the retrofit engineering process take?
Typically the engineering phase takes 4-8 weeks. Permit approval adds another 4-12 weeks. Construction duration ranges from 2-6 months depending on scope.
Q) Do I need a structural engineer even if my contractor says they can handle it?
Absolutely. California law requires all structural engineering work be performed by a licensed structural engineer. Contractors cannot legally perform engineering design or seal construction drawings.
