As part of any project, I am a big proponent of having a hands-on approach, and in this case an onsite approach.
I asked the client to let me know whenever they have a site visit and meeting with the general contractor so I can stay in the loop. When the topics have nothing to do with me, I use the opportunity to walk the site, take photos and make notes.
In this video short, I notice that there is only one cable pulled where there should have been 2 and was able to let the cabling contractor know. a change like that later would take much more time and money to address and fix.
