What is a hardware group in a door specification?
A hardware group (or hardware set) is a numbered list of all hardware items required for a specific door type, including hinges, locksets, closers, stops, seals, and specialty items. Each door on the project is assigned to a hardware group in the door schedule.
What is the difference between the door schedule and the hardware specification?
The door schedule is a tabular list of every door on the project with its size, material, fire rating, and assigned hardware group number. The hardware specification (Section 08 71 00) defines the specific hardware items within each hardware group.
What is a keying schedule?
A keying schedule defines the master keying hierarchy and individual key assignments for every lockable door on a project. It specifies keying system type, master key levels, key groups, and keyed-alike or keyed-different assignments.
What fire ratings apply to commercial door assemblies?
The five standard commercial fire ratings are 20, 45, 60, 90, and 180 minutes. Each rating level imposes specific requirements on door construction, frame preparation, hardware components, and seal packages.
What is a hardware submittal?
A hardware submittal is a detailed document prepared by the hardware distributor listing every hardware item for every door, organized by hardware group. The architect reviews the submittal for specification compliance before materials are ordered.
How does CDF support the Division 8 process?
