"I'm going to suggest that you first make friends with a good construction project manager, one that has the PMP (Project Management Professional) designation after his (or her) name. Get that person to go through the sequencing of trades on a given job site so you understand the interrelationship of the various trades' functions. Then get with someone from each of the trades and spend time as a go-fer for them. You'd be surprised how much you'll learn, and with boots on the ground, you'll have a much better understanding of the issues that confront each of the trades and why they're sequenced in a certain manner. You'll also learn how one supplier's or contractor's failure to perform timely affects the rest of the project."
Just to set the record straight about PMP's, there is some value and I do have one behind my name but I have also been working on my own house which was started in 1989 and is still not finished so I was able in my professional life as a PMP to complete numerous construction projects (Wireless, Cellular construction) it left me little time to manage my own life and the single resource I have working, me, my better half does the same thing I do, it is a 7 day a week 16 hour a day job which for now I am free of having just competed 502 sites in the Shenandoah Valley. I do know what the trades do but also track the schedule and the punch items, no job is done and acceptable and billable until all of that is done. As for building your own home, it is a very rewarding experience, when I started I did read everything there was out there, and in 1989 it wasn't on the internet as it is today, Journal of Light Construction was in print and it seemed every month it came out I was learning something about what I was doing at the time. We hired an architect friend who did all of the framing on the Queen Anne Victorian home and we have been finishing it from there. As a note there, never really understood the 22 1/2 degree angle impact to me until I became involved on finishing all of the 45 degree bump-outs and octagon towers on the house. Studying the building codes for the jurisdiction kept me mostly out of trouble, having a Father that was a retired journeyman electrician helped me with wiring those 3-way, 4-way, up to 6-way switch circuits, I asked him to come back at 93 and help me finish the wiring and make them all work, that was 23 years into an electrical permit and getting the final (very tolerant and understanding jurisdiction). Making mistakes along the way are part of construction if it wasn't there would be no such thing as "punch items". Just keep in mind what you see on the "reality" tv shows are not real life for you as a builder, your time will be your biggest factor in what you will be able to accomplish on your own, unless you are independently wealthy you will still have a real job. Festool, this forum has been great now that I have time to use the "green" tools I have been accumulating with income from my "real" job, the last part of the house to finish is the formal "parlor", all done in cherry wood and molding that I ran on a W&H molding planer in my "free" time. Bottom line it is a personally rewarding experience which has taken granted a long time but has been well worth it.
Best wishes in your efforts learning the trades. All of the above is personal experience from a project management professional (PMP) who has numerous personal unfinished projects and punch items.
