Which of the following items is not typically included in Division 16 of specifications?

Division 16 of specifications generally pertains to electrical work, which encompasses various aspects of electrical installations and equipment. While mechanical systems are integral to a building's design and operation, they fall under a different division in specifications, typically Division 15, which is dedicated to mechanical work, including plumbing, HVAC, and other systems.

In contrast, wiring methods, panel scheduling, and lighting controls are all critical components within electrical specifications. Wiring methods detail how electrical wiring should be installed, panel scheduling outlines the arrangement and specifications for electrical panels, and lighting controls address how to effectively manage and control lighting systems within a facility.

Thus, the correct answer identifies that mechanical systems do not belong to Division 16, reinforcing the distinction between electrical and mechanical specifications in construction documents.
