About us
Precision is our manufacturing standard
AMS BIM Services started as a two-person architecture and BIM consultancy. Today we're a 40-person team that designs, engineers, manufactures and services complete mechanical, electrical and plumbing systems.
Everything we do is coordinated in Revit and manufactured in our own CNC shop — which means the ductwork that arrives on site is exactly what the model promised.
