I haven’t worked in the field for quite a while but I have kept my skill set. Sure, we now have better CAD software and a lot of new building materials that weren’t around before. Green buildings have become a big issue: energy efficiency, insulation, water saving and recycling, etc. The construction site has evolved, too: new machines and more computerized processes. But nothing has come up that can’t be learned very quickly.
