In one of the previous companies I worked for, we used to do mostly concrete or steel commercial building projects. When we got a job which was entirely wood frame, they had assigned one of the project managers to the project, but since as a company we did not have the required experience, the project experienced additional costs and delays. Only then they brought a PM who was knowledgeable in wood frame construction. This is a different ball game, you need to have someone knowledgeable in that specific area.
