well in 73 years I was bound to learn something. My grandfather built all those ole row houses in Balto with white marble steps. My father built row houses out futher. My grandfather on the other side was a master plumber and they all tough me their trades. I picked up brick, block, flagstone and concrete work from my brotherinlaw. Drafting I picked up in schools and on the job. Electricity I learned in the electrical union IBEW28. Electronics I picked up in local classes and RCA courses, plus 32 years experience on the job.
When My home burned down, I drew up the plans using load tables from the library. I then fought the building permit bureau. Their engineer passed them with no problem. The electrical dept made me take the electrician test. A 4 hour test I aced in 2 hrs. the plumbing dept. head happened to be a graduate of Baltimore Polytechnic institute also, so the permit breezed thru.
I dug the footers,poured the concrete,erected the stud walls,installed the trusses in front and standard rafters in back,installed 2" EPS panels on the outside covered by a exterior paneling. Put 3" of fiber glass in the wall and inst 1/2" sheetrock on the inside. the roof is aluminum on 4" perlins. I wired and plumbed the house. The cabinets were premade as most are today in this area.
NOW
If YOU WOULD ASK ME WHAT PART REQUIRED THE MOST SKILL, i WOULD SAY, DESIGNING THE PLANS. The REST OF THE JOBS ARE FOLLOW THE LEADER TYPE WORK. GRANTED, THEY ALL REQUIRE THERE OWN SPECIAL SKILLS, BUT TO COMPAIR THEM IS APPLES AND ORANGES!
I HOPE THIS PUTS THIS DEBATE TO REST BEFORE WE ALL GET BANDED!
As for the original post, most work around here is price bid rather than hourly, although I am a barterer myself.
