Adding ducting or conduit or pipes to a wall is easy, you just drill or cut a hole. Adding a wall where there is already conduit and pipes poses more of a dilemma, especially if those things are adjacent to an existing wall or structure that the new wall is supposed to abut. I'm used to framing a new wall with it laying flat, then lifting it into place. That obviously isn't the right approach here. If I try to frame the wall in-place then I can't get to the bottom of the bottom plate or top of the top plate (if it touches the ceiling) to put screws through into the studs. If I frame the wall laying down, then I have to leave openings all the way to the nearest edge from each obstruction, which is not ideal.
What simple method am I missing here?
Edit: This is the space I am adding walls to. The walls will each be 9-14 feet wide, and about 16 feet tall. With few exceptions, they will each be adjacent to the concrete columns on both sides.
