Electrical Seismic Letter of Compliance

When time matters and quality is non-negotiable, our Electrical Letter of Seismic Compliance service provides the certified documentation needed to confirm that your electrical seismic installation complies with the approved design and applicable building code requirements.

Before issuing a certified Electrical Letter of Seismic Compliance, our engineers review the installation to verify that all required seismic restraints, anchors, braces, and supports have been installed in accordance with the approved design and current seismic codes. When required, we provide practical recommendations to resolve deficiencies quickly and help your project achieve compliance without unnecessary delays.

Our compliance reviews can include:

  • Engineering certification of compliant seismic installations 

  • Technical support throughout the project 

We deliver most Electrical Letters of Seismic Compliance in less than 24 hours once the required documentation and inspection have been completed, helping you stay on schedule for inspections, occupancy permits, and project turnover. Our clients rely on our speed, technical expertise, and practical engineering approach to achieve seismic compliance without unnecessary delays or overcomplicated requirements.

Electrical Seismic Design & Preliminary Report

A well-planned seismic design is the foundation of a successful electrical installation. Our Electrical Seismic Preliminary Report provides contractors with clear engineering guidance before work begins, identifying the seismic restraint requirements, anchorage methods, and bracing details needed to ensure a safe and code-compliant installation.

Our preliminary reports can include:

  • Identification of electrical systems and equipment requiring seismic restraint

  • Seismic restraint requirements for suspended electrical equipment

  • Seismic restraint requirements for roof-mounted generators and electrical equipment

  • Seismic restraint requirements for ground-mounted generators

  • Seismic restraint requirements for floor-mounted and suspended transformers

  • Seismic restraint requirements for electrical distribution panels and switchboards

  • Seismic restraint requirements for cable trays and electrical equipment racks

  • Seismic bracing layouts and locations for cable trays and larger conduits

  • Seismic restraint requirements for Lighting Fixtures Installed in Suspended Ceilings 

  • Anchorage requirements and attachment methods for electrical equipment

  • Installation details and engineering sketches

  • Applicable building code and seismic design requirements

  • Seismic calculations, where required

  • Equipment-specific restraint recommendations

  • Engineering notes and electrical installation guidance

  • Coordination with electrical drawings and project specifications

  • Answers to technical questions before and during installation

By addressing seismic requirements early, electrical contractors can install systems correctly the first time, reduce field modifications, minimize costly delays, and simplify the inspection process. Following our recommendations from the start creates a smoother path toward obtaining your Electrical Letter of Seismic Compliance and successful project completion.

Electrical On-site Seismic Inspection

Our on-site electrical seismic inspections can be performed before or after the installation of seismic restraints, depending on your project's needs.

A pre-installation inspection allows our engineers to review the existing electrical installation, identify which equipment requires seismic restraint, and provide practical recommendations before work begins.

A post-installation inspection verifies that all seismic restraints have been installed correctly and comply with the approved design and applicable building codes before issuing a certified Electrical Letter of Seismic Compliance.

Our inspections include:

  • Verification of electrical seismic restraint installation

  • Inspection of electrical equipment anchorage and fastener installation

  • Verification of seismic bracing locations, spacing, and orientation

  • Inspection of generators, transformers, switchgear, distribution panels, and other electrical equipment

  • Inspection of seismic bracing for electrical conduits, cable trays, equipment racks, and suspended lighting fixtures

  • Review of field conditions affecting electrical seismic compliance

  • Identification of installation deficiencies and required corrections

  • Engineering recommendations during construction

  • Final compliance verification prior to issuing an Electrical Seismic Letter of Compliance

During every visit, we work directly with electrical contractors to answer technical questions, resolve field conditions, recommend practical solutions, and help your project pass inspection the first time.

Electrical Remote Seismic Inspection

Our remote electrical seismic inspections offer a cost-effective and time-saving alternative to on-site visits for smaller scale projects. Using FaceTime or photographs, our engineers can perform a comprehensive review of your electrical installation without the need for travel.

Remote inspections can be performed before or after the installation of seismic restraints, depending on your project's needs.

A pre-installation remote inspection allows our engineers to review the existing electrical installation, identify which equipment and systems require seismic restraint, and provide practical recommendations before work begins.

A post-installation remote inspection verifies that all seismic restraints have been installed correctly and comply with the approved design and applicable building codes before issuing a certified Electrical Letter of Seismic Compliance.

Our remote inspections can include:

  • Review of photos, videos, and live video calls

  • Virtual review of electrical seismic restraint installations

  • Review of electrical seismic bracing layouts and installation details

  • Verification of seismic restraints for generators, transformers, switchgear, distribution panels and other electrical equipment

  • Review of seismic bracing for electrical conduits, cable trays, equipment racks, and suspended lighting fixtures

  • Identification of non-compliant electrical installations

  • Engineering recommendations and corrective guidance

  • Follow-up reviews after deficiencies have been addressed

  • Final compliance verification prior to issuing an Electrical Seismic Letter of Compliance

By eliminating travel while maintaining the same engineering expertise, our remote inspections help reduce project costs, accelerate project schedules, and provide a fast path toward electrical seismic seismic compliance. We work directly with electrical contractors to answer technical questions, review field conditions, recommend practical solutions, and issue a certified Electrical Letter of Seismic Compliance as quickly as possible.

Seismic Electrical Technical Support & Training

Proper seismic restraint installation begins with the right knowledge. Our Seismic Electrical Technical Support & Training service provides contractors, project managers, installers, consultants, and engineering teams with the practical knowledge needed to confidently design, install, and inspect seismic restraint systems for electrical equipment and distribution systems.
