The article is focused on the architecture of large cooperative ICT environments. The logical levels are the most important feature in the architecture. The paper introduces a system of three logical levels: the business architecture level, the application architecture level and the physical architecture level. Each level can contain several views --- either complete or partial views. Each level can have more than one instance. It provides a seamless platform for modelling how the business processes of collaborative engineering are running onto the architecture. UML is used as the modelling language. The instructions on how to use it are presented in the paper.
