Question

nccer 27105 - floor systems 48min the bottom ends of cross - bridging are not nailed in place until when? the subfloor is installed the building is closed in the wall framing is erected it is approved by the inspector

Explanation:

In construction, cross - bridging is a structural element. The bottom ends of cross - bridging are not nailed until the wall framing is erected. This is because the wall framing provides the necessary support and alignment for the cross - bridging. If nailed too early (before wall framing), it may not be properly positioned or may be affected by subsequent construction activities. The sub - floor installation and building being closed in come after the wall framing stage in the typical construction sequence. Approval by the inspector is a general quality - control step but not the specific trigger for nailing cross - bridging bottom ends.

Answer:

the wall framing is erected
