While ideally, wall anchors are spaced 3' off the corners of basement walls and then 6' apart, the real basement stabilization has real world needs. When the technician receives their design from the engineer, they will take that plan and measure out, then mark where the anchors should be placed. However, there might be site specific conditions that become apparent that require the installation technician to notify the engineer that the anchor placement needs to be shifted slightly. In most cases, it can be as little as 3" either direction to avoid a pipe. In other cases, the anchor faceplates are low profile enough that the wall anchor can be installed directly behind the pipe without problems!
