What is the minimum separation for duct paralleling other utilities?

Explanation:
When ducts run parallel to other utilities, a practical minimum gap is needed to protect the conduits and keep future work feasible. A separation of 12 inches provides enough clearance for installation tolerances, reduces the chance of abrasion or damage from adjacent lines, and leaves room for maintenance, pulling, and possible future changes without crowding neighboring utilities. Smaller gaps, like 6 inches, are too tight and risk contact or damage, while larger gaps such as 18 or 24 inches are generally more than necessary unless local rules require them.
