Andy, I think you're asking too much from skilled trades personnel, and it appears to me that you are at a point where your org chart needs to be re-vamped because, as you scale a business, you can't just use the same structure. Running 14 projects is a near-impossible task by yourself. As several others have pointed out, you really need to find some management help. Here's how it works in the civil construction side of our land development organization, from top-down:
VP Construction - responsible for all construction activities
Project Managers and Asst. Project Managers - liaise between the VP Construction and the Superintendents/Foremen, mainly handling schedule-tracking, budgeting, materials acquisition, and equipment mobilization
Superintendents - responsible for all aspects of day-to-day operations for a region (usually 2-3 projects) - advise/oversees the Foremen
Foremen - functional leads for a crew (for us, excavation crews and utility crews, because we don't do vertical construction, meaning buildings), responsible for doing the actual work safely and efficiently
Crew Members - perform work under the direction of the foremen
I think what you're needing is project manager(s). Construction management is a sub-discipline of civil engineering, but a some schools, it's a separate degree. A good way to start might be to talk with a university near you and see if you can find a student to work part-time or in an internship or co-op, and then, if you treat them right, and you do your part to train them, you could hire them upon graduation. It's not cheap, though. However, as with TJ parts, you get what you pay for.
