ASCE 7-22 VS30 Site Classification Requirements: DoReMi® MASW Turnkey Seismograph + SEISMOWIN Solution: QuakeLogic engineering guidance on seismic sensors,...
Streamline ASCE 7-22 VS30 Site Classification Using DoReMi® MASW Seismographs with SEISMOWIN
The latest ASCE 7-22 standard requires Vs30 shear wave velocity measurements as a key parameter for site classification and seismic design. This shift makes reliable, efficient, and accurate seismic characterization of soils more critical than ever for geotechnical engineers, structural designers, and regulatory compliance.
The DoReMi® Seismograph is the perfect solution. Its digital telemetry system with embedded electronics offers unmatched efficiency, scalability, and modularity. Each channel operates as an independent seismograph, enabling networks from 1 to 255 channels for projects of any scale. Lightweight, durable, and powered by a rechargeable battery with smart standby mode, DoReMi® ensures seamless field deployment and uninterrupted operation. With over 15 years of proven reliability and hundreds of global clients, it is a trusted standard in seismic surveys and geotechnical site investigations.
Paired with SEISMOWIN, a complete seismic data management and analysis suite, the DoReMi® becomes a turnkey solution for Vs30 determination. SEISMOWIN’s MASW (Multichannel Analysis of Surface Waves) and ReMi (Refraction Microtremor) modules provide advanced tools to analyze both active-source surface waves and ambient noise, ensuring flexibility in diverse field conditions. MASW delivers detailed S-wave velocity profiles comparable to borehole logs—without being affected by velocity reversals—while ReMi excels in noisy environments where passive surveys are preferable.
Together, DoReMi® + SEISMOWIN empower engineers to quickly and confidently obtain Vs30 values required under ASCE 7-22, streamlining the entire workflow from data acquisition to final reporting. In-house design, production, and support guarantee fast service, expert training, and customization to meet project-specific needs.

Executive Summary
Seismic sensors and seismographs convert ground motion into usable engineering data for site characterization, monitoring, event detection, and post-event analysis. This article is maintained as a QuakeLogic engineering resource for readers evaluating terminology, applications, instrumentation, and practical implementation considerations. The content is educational and should be reviewed against project-specific requirements, applicable standards, manufacturer documentation, and qualified engineering judgment.
Key Takeaways
- Start with the engineering objective, operating environment, required measurements, and decision workflow.
- Use calibrated instrumentation, documented configuration, appropriate sampling, and traceable data handling where results support engineering decisions.
- Interpret results in context; boundary conditions, installation quality, noise, bandwidth, and site conditions can materially affect conclusions.
- Use standards and references as guidance, not as substitutes for project-specific engineering review.
Technical Explanation
A credible engineering workflow links the physical system, the measurement chain, data acquisition, processing, interpretation, and reporting. For testing, that means documenting the input, payload, fixture, limits, safety controls, and acceptance criteria. For monitoring, that means documenting sensor type, placement, orientation, coupling, timing, communications, maintenance, alarm logic, and review procedures.
Engineering Applications
| Use Case | Primary Question | Useful Documentation |
|---|---|---|
| Research or education | What behavior can be measured, demonstrated, or repeated? | Test plan, configuration notes, input data, calibration records, and observations. |
| Infrastructure or facility monitoring | Is response normal, changing, or outside expected limits? | Baseline data, event records, thresholds, inspection notes, and engineering review. |
| Product or system selection | Which specifications matter for the application? | Measurement range, bandwidth, accuracy, environment, integration needs, and deliverables. |
