FEMA P-58 · ATC-138 Functional Recovery · ASTM E2026-conformant reports

Cover of an SP3-RiskModel executive summary report

Reliable loss results in minutes, a comprehensive client-ready report at the click of a button, and four license levels that grow with your project's needs.

How it works

  1. Describe the building

    Address, age, size, and structural system — SP3 fills in site class and seismic hazard automatically from the USGS models.

  2. SP3 builds the risk model

    Structural properties, building components, and responses populate from research-backed databases. Override any input when you want finer control.

  3. Run the analysis

    The engine computes full Monte Carlo FEMA P-58 results in minutes — losses, damage, downtime, and recovery.

  4. Deliver the report

    Comprehensive, professionally formatted reports generate automatically, with the calculations laid out transparently.

Decision outputs

Seismic risk decisions need more than one loss estimate. Every SP3-RiskModel analysis produces distinct, connected outputs — each a plain-English answer to a question your client is going to ask. The figures below come from the sample reports at the bottom of this page: an 8-story steel BRBF office building at 123 Main St, San Francisco.

01

Repair Cost

Quantify repair cost due to earthquake damage across every level of shaking or earthquake scenario.

0 25 50 75 100 % OF BUILDING VALUE DE MCEᵣ PGA (G) 20% MEAN (SEL) FITTED SUL MEDIAN 90TH PCTL
$11.7M repair cost at the design earthquake (20% of value) $34.6M repair cost at MCEᵣ (59% of value)
02

Exposure

How much of the building's value is at risk in an earthquake — and which parts of the building carry that risk, broken down by component group.

STRUCT 43.7% EXT FIN 19.9% CEILINGS 6.1% HVAC 2.8% OTHER NS 2.7% ELEVATORS 1.3% PARTITIONS 0.9% PIPING 0.6%
$45.7M maximum repair potential 77.9% of $58.6M replacement value
03

Loss Drivers

Identify which components are behind the repair bill and design targeted retrofit strategies.

73% RESID. DRIFT · 72.8% EXTERIOR · 7.7% OTHER NS · 6.8% PARTITIONS · 4.5% INTERIOR · 2.7% ALL OTHER · 5.5%
$38,290 expected repair cost in an average year 17% chance residual drift forces demolition at the DE
04

Structural Response

Estimate peak story drifts and peak floor accelerations at every story and ground shaking intensity — see where the system is working the hardest and where demands concentrate.

1% 2% 3% 0 STY 8 STY 1 PEAK STORY DRIFT (%) 1.6% DE MCEᵣ 475-YR
1.6% peak story drift at the design earthquake 0.74g peak floor acceleration at the roof, at the DE
05

Life Safety

The chance that someone in the building is hurt, due to both structural and nonstructural vulnerabilities.

0 1% 2% PROBABILITY DE MCEᵣ PGA (G) 0.43% ANY INJURY FATALITY
0.43% chance an occupant is injured at the DE 0 expected fatalities at or below the DE
06

Red Tag & Collapse

How likely the building is tagged as unsafe, needs to be demolished post-event, or collapses due to severe damage.

0 20% 40% 60% 80% PROBABILITY DE MCEᵣ PGA (G) 29% RED TAG DEMOLITION COLLAPSE
29% chance of an unsafe placard at the DE 2.1% chance of collapse at MCEᵣ
07

Recovery Time

How long until the building can be re-occupied, used for business, or fully repaired after the event, based on the ATC-138 Functional Recovery Methodology.

0 12 24 36 MONTHS TO RECOVER DE MCEᵣ PGA (G) 10 MO FULL RECOVERY FUNCTIONAL RE-OCCUPANCY
3 mo to full recovery at the FREᵣ 10 mo to full recovery at the design earthquake
08

What Blocks Recovery

Recovery isn't one number. Every simulation tracks which system keeps the building shut — jammed doors and stairs at first, then the long tail: elevators, power, water and HVAC equipment with long lead times.

HVAC 61% ELEVATORS 57% ELECTRICAL 36% POTABLE WATER 35% INTERIOR 20% ENCLOSURE 20% % OF SIMULATIONS · 3 MONTHS AFTER THE DE
83% probability of more than 3 months of downtime due to MEP damage 36% probability the building is still not functional after a year
09

USRC Rating

FEMA P-58 results mapped onto the U.S. Resiliency Council's three dimensions — Safety, Damage and Recovery.

SAFETY DAMAGE RECOVERY
4★ Safety — serious injuries unlikely 3★ Recovery — function within weeks to months

Values plotted from the sample SP3-RiskModel reports below — FEMA P-58 loss methodology with ATC-138 (Beta) functional recovery, SP3 Platform v15.0.0 (USRC rating summary from the v14.7.1 sample). A sample model at a real address, not a client project.

Key capabilities

01

Building-Specific Modeling

FEMA P-58 made simple: SP3 automates the methodology around your specific building, and every automated attribute can be overridden.

02

Seismic Hazard Lookup

Site class and hazard fill in automatically from the USGS Vs30 model and the National Seismic Hazard Map — no separate hazard study needed.

03

Design Database

Automated design models derive your building's structural properties from its age, governing design code, site, and configuration.

04

Response Prediction Engine

Structural responses are estimated automatically from building-specific structural properties — no structural model required.

05

Component Population Engine

Building components populate automatically from age, occupancy, layout, and structural system — a realistic inventory without the manual takeoff.

06

Stability Calculations

Building stability checks run automatically using the FEMA P-154 methodology.

07

Recovery Time Modeling

Downtime and recovery predictions use the ATC-138 Functional Recovery Method — the modern standard for recovery-based design.

08

Fast, Scalable Analysis

Full Monte Carlo risk results in minutes, scaling from one building to entire inventories.

09

Automated Reports

Comprehensive, client-ready risk reports generate automatically — see the samples below.

Automated risk analysis reports

Hand your client a report, not a spreadsheet. Every license level generates professionally formatted documentation — repair costs, reoccupancy and functional recovery times, charts, and the calculations behind them — so results are easy to defend and easy to understand.

License levels

Four levels that grow with your project — from due-diligence loss estimates to full control over every input, with recovery modeling available at either tier.

Standard

Building-specific seismic risk assessment with loss predictions for SEL, SUL, annualized losses, and component group loss breakdowns — the right starting point for most due-diligence work.

Standard + Recovery

Everything in Standard, plus recovery time modeling with predictions for reoccupancy and functional recovery — for when downtime and business interruption matter.

Advanced

Everything in Standard, plus detailed control over building components, structural responses, and building stability — built for engineers who want to define every input.

Advanced + Recovery

Our most complete level: full advanced control plus recovery time modeling for re-occupancy and functional recovery — the choice for resilient design projects.
