> Last month, I began a three-part series of articles about how the newly released Revit Systems BIM (building information modeling) software for MEP (mechanical, electrical and plumbing) engineering improves the MEP design and documentation process. This month, I drill down into mechanical design, examining how that building discipline can take advantage of BIM. Next month, I'll do the same for electrical design. <
