The issue of outsourcing to offshore companies is mostly an emotional issue. Feelings and beliefs aren't debatable. The reason to offshore is economic. There isn't much to debate here either. It saves money.
Architects have been outsourcing for at least a hundred years. By this I mean using consultants for engineering design, for interior design, for landscape design, for renderings, for signage, for 3D digital models that allow fly-bys and walk-throughs. Some of this can be easily off-shored as well.
We were contacted by a firm based in Lithuania almost ten years ago. They were offering to do 3D work and rendered images for about 25% of the 'normal' price. Their British manager made communication easy. We found ourselves in the position of being able to offer this type of service on almost every project because of the low cost.
For the past five years I have been looking for a way to outsource detailing and drafting tasks as well. Here is what we are learning.
