Topics The following will be covered: • Executive summary • Background: FEMA 154 and ATC-20 • How ROVER works and its features • Support and training of ROVER users • Additional resources
Executive Summary • ROVER: fast, free, mobile software for building professionals to do seismic-safety assessments. • Web-based: so works on Android, iOS, …, though needs data connection • Integrates with other USGS & FEMA tools for real-time seismic monitoring & risk analysis • Bona fides: FEMA investment; FEMA 154 and ATC-20 standards; Cal EMA adoption • Mature training materials, support options • Extensively tested • FEMA goal for ROVER is risk mitigation
ROVER in the Disaster Cycle Inventory buildings with FEMA 154 module; plan for response to low-scoring buildings; practice response in ShakeOut; estimate risk with HAZUS-MH ShakeCast-ROVER edition estimates tag colors automatically Import ROVER database to building-permit system Use ROVER ATC-20 module for safety tagging
Background: FEMA 154 • ATC for FEMA, 1988, 2002: pre-earthquake rapid safety screening • Designed for building professionals • Used 100,000x • Reduced US Navy’s detailed evals by 2/3rd • Challenges: hazard, transcription, & management
Background: FEMA 154 S ≥ 2 Possibly hazardous; detailed eval required Probably not hazardous
Background: FEMA 154 S < 2 Possibly hazardous; detailed eval required Probably not hazardous
Background: ATC-20 • ATC for OES (1988…) post-earthquake safety screening • Used by engineers, architects, building professionals • Used 100,000x or more esp. after Loma Prieta • 104,000 in Northridge • Challenges: transcribing, management
ATC-67 Project Objectives • Mobile software for FEMA 154 & ATC-20 • Add digital features to the methodology • Training materials • Field tests, pilot tests, demo projects • Dissemination plan
Product OverviewRapid Observation of Vulnerability and Estimation of Risk
ROVER hardware: 1 smartphone or tablet (client) per inspector, + server • Collect field data with any web-connected smartphone or tablet: Android, iPad, Blackberry… • Enter field data through browser directly into server • Server is any PC • Optionally hire a service to host data, and provide server
Post-earthquake data service in US • MCEER’s Katrina recon team had data service when arrived 6 Sep 2005 (landfall + 8dd) • TCLEE’s Alex Tang on ShakeOut: “There is no record of damage to telecommunications network for earthquakes with PGA of 0.4g and below.” Power in ShakeOut 1 day 1 wk 1 mo Epicentral region Optimistic restoration estimate Cautious estimate

Built-in database • Remote consulting • No need for ad-hoc database • Gets lat/lon automatically from GPS or address • Keeps photos & sketches • No transcription; less data-entry error • Consistency across jurisdictions or owners • Integrates with other databases
Soil lookup; site-specific hazard • Server looks up each building’s soil type & seismic hazard from USGS databases using its latitude & longitude • Server adjusts the building’s score accordingly
Disadvantages versus paper • Need for hardware • But since 2011, most mobile phones sold are smartphones, so inspectors probably already own the required hardware • 30-60 min extra training • Can more easily modify paper forms • Can’t crash a stack of paper • But you can carry paper forms to the field as a backup, and transcribe them to the server at days’ end
Status • Available for free online (www.roverready.org) & via CD in FEMA warehouse • ROVER software • Training materials • Several pilot tests have been performed (LAUSD, University of Utah, Structural Engineers Association of Utah, and others) • Cal EMA has added ROVER to its Safety Assessment Program (ATC-20 evaluator training) • Online community established through ROVER Ready Alliance webpage & LinkedIn ROVER User Group • Paper-based FEMA 154 is still an option
Tests to date Los Angeles Unified School District Nov 2008 Bob Spears, LAUSD: “We want to expand our ROVER teams and make them part of our annual District-wide earthquake drill.” Utah Seismic Safety Commission Oct 2010 Glen Palmer, SEAU: ROVER is “So much easier to use in a quick and effective way” Matt Robles, Salt Lake City structural engineer: “For structural engineers, [ROVER is] ... the single greatest advancement in the use of smartphones that I can think of.”
Use for Utah schools • Utah schools pilot study: 128 buildings • After pilot, added 2500+ buildings • Champions: Lt Gov Bell, Barry Welliver • HB 278 S01 requires RVS of pre-1975 buildings as prereq for bonding. Full schools inventory is funded, likely will be largely done with ROVER.
Maintenance & user support • User-community website & LinkedIn group will provide announcements and updates • User website will offer helpdesk services and users can post questions • FAQs
Typical pre-earthquake uses • Inventory buildings & critical facilities • Identify and prioritize mitigation targets • Enhance municipal and public communication • Assess risk for emergency planning with HAZUS-MH
Typical post-earthquake uses • Do safety tagging • Optionally prioritize tagging with ShakeCast • Remotely coordinate tagging • Document post-earthquake inspection efforts
