Knock. Knock. Who’s There? Door Hardware And Lots Of It.


One of the best parts of any job is discovery: learning new things about things you already thought you knew.

In my relatively new position at Archi-Technology, I’m constantly learning about something new every day. Like what a “butterfly diagram” is and how it can help better connect buildings and occupants to each other and the world. Or how many miles of cable are still required to enable Wireless Access to the Internet. Or why the full name of the BICSI trade association seems to have nothing to do with its acronym.

Another topic I never gave much thought about prior to this position is Door Hardware and, more specifically, how complicated it can be to select and install the appropriate parts, components and hardware sets that meet the owner’s project requirements. With so many doors in commercial buildings being connected to networked technology systems like Security (think video surveillance) and Door Access (e.g., swipe cards), Door Hardware is anything but old school.

Some of the things that make Door Hardware so complex include:

  • Every door requires numerous hardware sets based on required functionality that can include more than 100+ parts per door. Sets include levers, roses, escutcheons, latches, etc.
  • A project can include hundreds of doors with different functionality combinations that need to be coordinated through each project phase.
  • In addition to functional requirements, aesthetic considerations for finishes add another dimension to specifying products.
  • Door Hardware sets usually need to integrate with low-voltage networked building systems such as Security and Door Access.
  • Access devices such as keys, swipe cards and fobs bring other issues that need to be addressed in planning and carefully coordinated to avoid costly Change Orders.

Originally published in 1999 by Architectural Record, I found this article to be an excellent overview of the myriad issues associated with meeting an owner’s Door Hardware project requirements:

“The Ins and Outs of Door Hardware” by Charles Wardell and Wendy Talarico.

What’s the biggest Door Hardware challenge you’ve ever faced on a project and how did your firm resolve it? Archi-Technology would love to hear your experiences and share advice on this subject.
