HOK has two new blogs that join the Revit blogosphere. HOK Green BIM and HOK Cad Solutions are the vehicle they've decided to use to share the wealth so to speak.
They have been hard at work on lots of cool projects using Revit and pushing what BIM and BuildingSMART means to their firm and now they are sharing some of that hard earned knowledge. Be sure to keep an eye on them. Also don't forget their website 4BIM which went live some months back.
