Which bid package items are grouped together as rough-in electrical work for insulation considerations?

• A. 07 62 00 - Sheet Metal Flashing and Trim & 07 92 00 - Joint Sealants
• B. 26 05 34 - Conduit for Electrical Systems & 26 05 37 - Electrical Boxes
• C. 09 21 16 - Gypsum Board Assemblies & 09 91 23 - Interior Painting
• D. 20 07 19 - Piping Insulation & 23 07 13 - Duct Insulation

Answer: (B)

Grouping bid package items by trade and phase helps you see which components belong to rough-in electrical work and how insulation details come into play. Rough-in electrical work involves installing conduits (conduits for electrical systems) and electrical boxes before walls and ceilings are closed, so these elements are planned together because they occupy space, determine penetrations, and influence how insulation and fire-stopping are applied around them. The pair that represents electrical rough-in is conduit for electrical systems and electrical boxes, since both are installed during the rough-in stage and require coordination with insulation detailing at penetrations and interfaces with walls. The other options either relate to envelope materials and sealants, finishes, or HVAC insulation, which are not grouped with rough-in electrical work.
