An employee-owned Omaha engineering firm (founded 1967) providing mechanical, electrical and plumbing engineering alongside a fire protection and life-safety practice. Its fire and life-safety work includes fire and life-safety studies plus the design of fire sprinklers, detection and alarm/mass-notification, smoke exhaust, high-expansion foam and clean-agent suppression systems for new and renovated facilities — analyses that are an aid to the professional judgement of the project and code-review teams, not a substitute for it.
