ATS has been serving the community since 1969 and went online in 2007. In 1969, Lou Petro launched ATS with the mission of making specifications easier for architects, engineers, and the design community as a whole. ATS would compile manufacturers’ product binders into one ATS Master Specification Manual to make the lives of Mechanical Engineers easier . From there, the company grew and continued to innovate and create timesaving solutions for the design community.

Today, the ATS Spec Tool has been online for 10 years and has built over 60 000 project specifications and assisted over 35 000 users from an ever-growing design community throughout North America.
