While a vertical schedule is typically specified and preferred by an architect, this standard describes both horizontal and vertical formats. Project specifications typically specify that hardware schedules are required to be created by an AHC.
6. If product substitutions requests are allowed from what was originally specified, the request process is typically specified in Division 01 of the Project Manual, otherwise known as the specifications.
The substitution request requirements are typically asking for product data and proof the requested substitution will meet the same grade, function, application, aesthetic, and quality of the originally specified product. It is recommended all substitution requests be submitted within the procedures as outlined in Division 01, Section 01 25 13 Product Substitution, and on CSI Substitution Request Forms.
One should be cautious of what is considered an ‘equal,’ as standards refer to the minimum standard, but there are some manufacturers, products, and solutions that go above and beyond these minimums. It is recommended substitution requests and approvals not be taken lightly as sometimes the substitution is proposed or taking place to strictly save money or to become more competitive on a bid to win the project contract to supply the door hardware without considering the item’s quality or durability. Typically, with door hardware, you get what you pay for. This means if you are saving money on an item, it is likely it is not of the same standards and quality as the originally specified device.
Conclusion
Following the DHI Sequence can help ensure all components of an opening have been addressed and no items were missed. By going through each step in sequence, it is easier to focus on what is required—the opening comes together like a puzzle. It is also very important and necessary to coordinate with other relevant specification sections, such as hollow metal or wood doors. By cross-referencing sections, one can see where one product can affect another, such as with coordinating door and frame preparations for hardware or the coordination of who furnishes materials such as a power supply. These are both typical items that can be assumed by others, and can be missed or left out of a bid, submittal, or, worse, installation when the building
is ready to open.
With all the items to take into consideration, one can see why a door opening is not something to just walk through. Among other things, with the proper components or assemblies, applications, functionality, code and standard compliance, and installation, lives can be saved and things will operate the way they are intended for the user without the massive punch list issues for which door hardware can be known.

Most of us might think that there is only one type of lock, which is the one we use to get in and out of our homes. When in reality there are many. Like in the second picture, this looks like the type of door you’d see in a bathroom, judging by the mosaic tile. For whatever lock you have, do know that you shouldn’t fear from locking yourself out. A skilled locksmith would be able to get into even the most stubborn of locks.
