Sigma has enjoyed a long history of excellence, forging new paths blending computer science with hydraulic engineering. Being a visionary in the field, Mr. William Bollinger founded Sigma in 1974 and established the software as the leading technology in automated hydraulics calculations, along with the equally inovative products POLARIS, CadONE, and QuickDraw.
Using computer technologies from a PC terminal with dial-up access to mainframe calculations, to DOS, and then Windows platforms, the brand Sigma and Mr. Williams’ ingenious PLines has been synonymous with speed, accuracy, and cost savings to fire protection contractors, engineers, approving authorities, and insurance companies in four continents.
Repeat business and loyal customers indicate our dedication to quality software. We think you will agree with the growing number of customers world-wide who depend on Sigma's software to 'deliver the goods'.
