Here is a situation that frustrates any controls or service technician.
7:30am: Receive device to be installed having never seen job site or equipment. I gave 8 hours as an example.
8:30am: Arrive at job site to review project. Oops have to run conduit, sensor wires, make mounting brackets and etcetera.
Make list of necessary materials and call back to dispatch to find closest supply store.
9:30am: Arrive at local supply store in hopes that they carry all material needed. Gather materials after rummaging through unfamiliar store and head back to job site. Ok lucky here got all of the necessary materials, as you know this almost never works this way. Usually need to make multiple trips to multiple vendors.
10:30am-12:00pm: Back to job site to begin installation. Notice 4.5 hours of the 8 used and only 1.5 actually applied to installing and again this is being nice if you consider that chances are the time used to get materials was for a part of the job that was not included in the 8 hours.
12:00pm-12: 30pm: Lunch, Ill be nice and say lunch is in the van but bologna and chips sure gets old.
12:30pm-4:00pm: Installation not complete. Time is up, and now I am over on labor. I still have half a days worth of work.
In actuality most of the 8 hour projects like this end up being 16 hour or more projects. The solution to this is to NEVER send a technician to install something without having them review the project first hand, unless you are know exactly what the installation process will entail and have all of the necessary supplies ready. Even then be sure to thoroughly review your plan of attack and if the installer has questions you cannot answer, than you need to accept the fact that your project is going to go over.
