Why you should avoid identical marks on a multi-building site

 

When marks appear multiple times across different buildings, we recommend using a prefix to distinguish the marks by building. This will identify the building and the mark number for easy reference during the submittal review of the hardware sets.

The prefix, or group should reflect the way the buildings are identified on the site.

  1. For Buildings A, B, and C, you can use A100, B100, C100 to distinguish the different marks.
  2. Building marks can also be grouped, i.e. 100, 200, 300.

 

Reasons to avoid identical marks (both type and instance)

Save Time and Money!

1. Avoid unnecessary RFI's during bidding.

  • Multiple openings sharing the same mark number or type but not identical in configuration, size, panel type or rating will generate RFI's from bidders.
  • If multiple openings share the same mark number or type and require different locking functions (operations) this will confuse bidders, generating an RFI.

2. Avoid unnecessary confusion during the design, construction and procurement process.

  • Multiple openings sharing the same mark number or type with different hardware sets create confusion.  It takes extra time and effort to find the location of doors on the plan and match them to the proper hardware set
  • Multiple openings sharing the same mark number or type with different hardware sets create confusion when ordering the hardware.  It takes extra time and effort to properly allocate hardware for each door.
  • Multiple openings sharing the same mark number or type with different hardware sets create confusion when installing the hardware.  It takes extra time and effort to properly determine which doors belong with which set and confirming proper installation of correct hardware at each opening.
