A factor of .94 is usually applied to insulation area in order to account for deleting the area of the framing members.
1,990 sf x .94 = 1,871
$4,700 / 1,871 = $2.51/SF cost, or $0.63 /sf/inch of thickness.
$0.63 x 13" (current R-49 open cell foam I have a cost for) = $8.19
My current quoted cost for open cell foam is $4.60/SF ($0.36.SF)
For a one-off job for a private owner with a lesser quantity of a lesser thickness (more set-up & travel time per SF) and unknown conditions, seemingly expensive, but maybe not too bad.
It was the two hour lunches that took it out of me.Riding around in a $100k truck in shorts and flip flops while talking on the phone all day and forgetting to pay invoices seems pretty difficult.
Candidly, our own project managers (pretty much the core of any GC) work way too hard for my liking. If they are doing a good job, those guys are cranking all the time.
"Riding around in a $100k truck" is running from job to job (always one job too many) trying to be on time for meetings and making sure your subs aren't doing the wrong thing again and trying to accommodate the owner's ill-defined 25th change since your started on this "simple job". "Talking on the phone all day" is ordering materials, scheduling and hearing "the dog ate my homework" from subcontractors and suppliers multiple times a week. "Forgetting to pay invoices" is a universal problem because they are required to compare the invoice to the (dynamic) job cost and proposals to make sure everything tracks. Hard to run jobs while sitting in an office dicking around with paperwork. The "shorts and flip-flops" are inexcusable fashion blunders.
I ran jobs awhile and was glad to be an estimator living from deadline to deadline instead of the constant soul-sucking grind.
