More information on hot tap operation and detail, refer to this site. In this post, I would suggest the WBS and activities for a hot tap detail construction schedule.
Sample WBS are as follows;
1 Area
1.1 Work pack
1.1.1 Tie-in No
1.1.1.1 Off site Fabrication
1.1.1.2 Preliminary Activities
1.1.1.3 Execution
1.1.1.4 Post Activities
Activities such as fabrication of hot tap (split tee type or stub type), blasting and painting, delivering to site are of off site fabrication WBS.The preliminary on site construction activities before hot tap operation are as follows;
