AIE Began in 1983 to Serve Customers

Alternatives in Engineering (AIE) was founded by Robert Warmann in 1983. While working for an insurance company, he was approached by a client looking for someone to help make fire protection decisions with the client’s needs, not the insurance company’s best interests, in mind. That’s when he decided to start AIE. 

It all started with Loss Prevention Site Surveys on warehouses and distribution centers to help clients make small changes that would lower insurance costs. The business grew fire protection services in St. Louis to include fire hydrant flow tests to determine if adequate water flow and pressure were available to supply new sprinkler systems and fire pump testing at retail locations. In the mid-1990s, AIE moved to its current location near St. Louis, Missouri and began expanding.
