Inberg-Miller Engineers believe that job site safety is our top priority and will continue prioritizing safety while performing work at your site. We have developed this long-standing culture of safety by conducting weekly safety meetings company-wide, weekly office safety meetings, job site tailgate meetings, performing job site analyses (JSAs), attending site-specific safety training at various facilities, and attending annual company-wide meetings at our yearly corporate safety week. We are proud of our low safety incident rates and the numerous safety awards we have received through the Wyoming Contractors Association for zero-incident rates based on man-hours worked.
