How West Valley Construction Cut Safety Events 97% with Samsara AI Dash Cams

West Valley Construction, a California underground utilities contractor operating 600 vehicles across 12 locations, deployed Samsara’s Connected Operations Platform including AI Dash Cams and Fleet Telematics to replace disconnected manual systems. Within four months, safety events dropped 97% and the company went from award to full implementation in under 100 days.

Challenge

West Valley Construction’s prior telematics platform provided basic metrics without camera integration, making meaningful safety coaching difficult and leaving no visual context for incident investigation, while limited automation and API access made it impossible to manage assets and driver assignments at the scale the company’s growth demanded.

Solution

West Valley Construction deployed Samsara’s Connected Operations Platform with AI Dash Cams, Fleet Telematics, and Asset Tags — integrating fleet, safety, and maintenance data via Samsara’s open API into a single system of record connected to HCSS, Power BI, and HR systems, with a phased 100-day rollout that included driver trust-building before scoring went live.

Tools & Technologies

What Leaders Say

There was a lack of automation and limited ability to manage assets and driver assignments at scale. With our growth, it wasn’t possible to maintain the level of oversight we needed. Now, we take action on data rather than administering it.

Ryan Haas, Director of IT, West Valley Construction

Our drivers are proactively checking their scores and acknowledging events—they’re self-correcting and changing their behavior. Samsara shows our people taking ownership and improving.

Full Story

West Valley Construction is an employee-owned underground utilities contractor that has served California for over 60 years. Operating 600 vehicles and 600 tracked assets across 12 locations with a fleet that logs six million miles annually, the company builds and maintains the buried infrastructure — electrical conduit, water lines, gas systems — that keeps California communities running. At that scale, fleet safety, vehicle uptime, and asset visibility are not peripheral concerns but core operational requirements.

Before Samsara, West Valley's telematics vendor provided basic metrics — harsh braking, acceleration, speeding — but no camera integration. Without visual context for driving events, safety coaching conversations were difficult to run and harder to make stick. Operationally, the previous platform lacked the API access and automation West Valley needed as the company grew. Leaders were administering data rather than acting on it, and manual processes for user provisioning, asset management, and maintenance tracking consumed hours that could have been spent on field operations.

West Valley selected Samsara after a cross-functional evaluation and went live in under 100 days from contract award — a rollout that included communications, hardware installation across 600 vehicles, driver training, and API integration with HCSS Telematics and the company’s HRIS and accounting systems. AI Dash Cams provided paired video and telemetry for every safety event, enabling precise coaching and driver exoneration. Fleet Telematics automated maintenance triggers by feeding real-time mileage and engine hours into service scheduling. Samsara’s open API connected fleet data to Power BI, eliminating duplicate data entry and creating a single record across systems. Drivers were given a 30-day ramp-up period before scoring went live, building trust and adoption ahead of accountability.

The safety results were immediate and dramatic. Within four months of rollout, safety events dropped by 97%, driven by in-cab audio nudges, a driver self-coaching app, and a recognition program that shifted accountability onto drivers themselves. In a single month, video evidence supported five driver exonerations — incidents where footage cleared drivers of fault in third-party claims. Drivers began proactively checking their own scores and acknowledging flagged events, a behavioral shift the safety team had not previously been able to achieve with text-only telematics data.

West Valley now operates Samsara as the central system of record for its fleet. Automated workflows feed data from GPS, cameras, and maintenance systems into unified reporting, freeing the operations team from manual reconciliation. The 100-day implementation timeline demonstrated that a 600-vehicle fleet with complex integration requirements — multiple business systems, phased driver onboarding, custom API work — can be migrated to a new platform without disrupting field operations.
