I normally number the door in a clockwise pattern, separating the exterior door list from the interior door list.
Number the doors using a permanent marker either at the top hinge and/or the top of the door along the lock edge. Numbering the top of the door will require a stepladder to read it. But there is less likelihood that the top of the door will be painted as the hinges sometimes are.
Ask a few important questions, starting with ” When was this building built?” As an example, I toured four different facilities including a hospital and college in order to take photos for this article. Several facilities are continually under construction. However, on several of the buildings, the lock hardware is not up to current code as buildings were built from the 1940s on.
With the different laws and codes throughout the country, servicing locks and door hardware on a building that is not up to code should be carefully considered. To start off, legal interpretation can be different from jurisdiction to jurisdiction and possibly from person in authority to person in authority.
Is the service a repair (considered maintenance) or an upgrade (considered building department)? There is an important difference. When doing a repair, the Fire Department is the authority having jurisdiction (AHJ). If the service is considered an upgrade, the authority having jurisdiction is usually the Building Department. Building Departments require permits and fees, as they can be a profit center for the local government. More important than a permit or fee, the Building Department may require the building be brought up to current code.
Doing the job may trigger some action by the Building Department. There is merit in discussing the job with the Local Authority Having Jurisdiction (LAHJ) prior to starting any work. Before talking to the LAHJ, clear it first with the building owner or representative. Ask the AHJ if the contracted job is under his or her jurisdiction and what implications to consider.
Note: It is a good idea to get to know the Local Authority Having Jurisdiction prior to calling upon them for an actual job.
When you are doing the site survey, look at each door, jamb and the lock hardware to determine if the opening is fire rated. Usually, if all of the hardware is fire rated, the opening is fire rated. You should note on the site survey what components are fire rated.
Also look carefully at east facing exterior doors. A common problem for some buildings that have non-reinforced hollow metal doors is warping due to direct sun. As a result, as the door heats up it warps, distorting the shape. This makes the door hard to open and hard or sometimes not possible to close. For a while, the door will close when it cools down until the warpage becomes permanent. Locks mounted onto these doors have excess wear and will most likely malfunction or not be able to close as a result.
These are a few points to consider when providing your customer with the information necessary to make important decisions and for locksmith to understand the job site in order to accurately provide a quote.
