I need help understanding the process of setting up the BONE structure critical path method table in excel, specifically the immediate predecessors for the BONE method.

1. Using Excel and the technique illustrated in this YouTube video: Dr. Harper's Classroom, build a critical path analysis table for each type of structure (Wood Frame and BONE). The information in the table and notes below define the two processes. Notes: A BONE structure includes frame, roof panels, and insulation, and can be assembled on site in an estimated 3 days. ** At the rough-in stage, the basic electrical, plumbing, and HVAC lines are laid in, without making final conncections to interior fixtures. *** Using a BONE structure changes the precedence constraints as well as the activity durations. The dimensional accuracy of the BONE structure eliminates the precedence constraint that interior finishes (countertops) must be ordered after framing; instead, interior finishes can be ordered immediately after obtaining a building permit. With BONE, the slab is poured after installation of the BONE structure (the order of activities 5 and 6 are reversed). The slab must be completed before any of the following activities can occur: installation of dorrs, windows, plumbing, electricals, HVAC, and roofing
