I know you PM'd me about some car wash stuff but I was thinking more along the lines of a truck wash. I just looked up online what this is and maybe I can help. I had a GC reach out to me last year with several of these same type washes, and their typical E-budget was $400k. The wash vendor would install/mount all of the wash components and make the connections between each motor/sensor etc to the adjacent control panel. The electrician would provide the main service and route power to each control panel. The lighting fixtures were installed by the electrician. That's the type of questions you need to clarify is who will install and connect what. The electrician was also responsible for routing power across the site to the vacuums and any site lighting, as well as the entry payment kiosks.
