what is the "customary", or "typical" procedure a homeowner would take when doing a project as a basement finishing, or remodel of say a wooden deck, or perhaps adding a room ?
specifically, say Joe Public, calls up several contractors for quotes. they all survey the job, and write up their bids.
question - what level of detail should those bids encompass?
for example, adding a new room - should their bids include the specifics of the foundation ? (ie. preparation, use of wire reinforced mesh, gauge of mesh, or maybe rebar - distance between rebar, PSI rating of concrete, gravel depth, type of vapor barrier, etc, etc). how about details regarding the type of hardware used on the studs or ceiling joists ? should it spec out specific brands (ie. Simpson, or whatever) ? and details such as types/sizes of nails to use.
i've read plenty of horror stories of clueless contractors (and equally clueless homeowners), both parties having no idea of proper industry practices.
is it customary to allow a contractor to go ahead and just take it on faith (or perhaps their reputation), that they will conform to accepted industry standards (code inspections not withstanding) ?
OR - is the level of detail that i'm harping on something an architect for a project, would be the only person who would be involved in that level of specification ?
how do you decide if an architect should get involved (on say a basement refinish project, or room addition), vs. having the contractor work of a set of rudimentary drawings ?
what do typical contracts spec out ? - for instance, if later down the road, nails start corroding - is it my fault for not spec'ing out specific quality nails ? that's why i want to know what level of detail is customary on a contract. do i have to spell every little thing out, or are there accepted norms in the building industry that competent contractors adhere to ?
