|

|
||
I've been trying to be alone with my thoughts more
|
||
recently. It's almost bizarre how working in silence
|
||
for an hour makes the thought of music or an audiobook
|
||
seem overstimulating, It feels right, though.
|
||
|
||
To want to converse with myself rather than let my
|
||
superego be drowned out by appealing sounds or a
|
||
fantasy story I've already heard, or obscure facts
|
||
about a game I've never played and never will.
|
||
|
||
I still relapse, of course, a lifetime (albeit
|
||
a short one) of unhealthy interaction with computers
|
||
will do that, but I'm making quick progress.
|
||
|
||
I watched a video yesterday that suggested that
|
||
it might be my growing understanding of computers
|
||
rather than my self discipline that's lead to this
|
||
change in the dynamic between me and them. That,
|
||
in understanding _how_ they function, I've turned
|
||
them from _devices_ into _things_, which lack
|
||
the mystical allure of the former. Whatever
|
||
the reason, it's good progress as far
|
||
as I'm concerned. It feels good to be introspective
|
||
and to have time to build skills people care about,
|
||
like music and style and... birdwatching...

|
||
A significant change from Ace to PDI in my mentality during takeoff
|
||
is that I now tend to expect that (within reason)
|
||
"holes" in takeoff scripts are _intentional omissions_,
|
||
not holes in cost coverage.

I was updating my notes,
|
||
filling in gaps in scripts based on Joel's,
|
||
when I noticed a strange paragraph:
|
||
|
||
> [!quote] `OneNote`/`Joel Take-off`/`Misc. Notes`
|
||
> Drop Down Ceilings vs. GWB (Gypsum Wall Boards)
|
||
>
|
||
> Drop down ceiling is technically "Exposed" (the real term should be accessable),
|
||
> so Romex and SER is not permited. Will need to use MC.

|

|
||

|
||

|
||
> >
|
||
> > Types NM and NMC cables shall not be permitted as follows:
|
||

|
||

|

|
||

|
||

|
||
> > in other than one- and two-family and multifamily dwellings
|
||
|
||
This analysis of 334.12(A)(2) is flawed.
|
||
|
||
Based on the [[nfpa-70_100_definitions|Article 100]] definitions
|
||
of [[nfpa-70_100_definitions#Exposed (as applied to wiring methods).|exposed]]
|
||
and [[nfpa-70_100_definitions#Dwelling, Multifamily.|dwelling]],
|
||
[[nfpa-70_334_nm-cable#334.12(A) Types NM and NMC.|334.12(A)(2)]]
|
||
can be paraphrased as follows:
|
||
|
||
> [!cite] NEC 334.12(A)(2), pp.
|
||
> Types NM and NMC cable are not permitted to be installed
|
||
> in accessible spaces above suspended ceilings,
|
||
> _except in buildings containing one or more dwelling units._
|
||
|
||
The prohibition of 334.12(A)(2) _never_ applies to apartments or condos,
|
||
And only applies to hotels and dormitories on a basis of AHJ interpretation
|
||
(See [[multi-family-dwellings#Are Hotels Multifamily Dwellings?]]).
|
||
|
||
It's unclear to me if this a genuine misunderstanding
|
||
or just a [[heuristics|rule of thumb]] to cover the case
|
||
that guestrooms are not interpreted to be dwelling units.
|
||
If it's the latter, I believe it's far too conservative
|
||
to be used whole-cloth on all estimates.

### "Feeder"
|
||
|
||
#topic/construction/electrical #original-format/digital-text
|
||
|
||
The NEC definition of feeder is quite strict.
|
||
I'm certain I misuse it frequently.
|
||
|
||
![[nfpa-70_100_definitions#Feeder.]]
|
||
|
||
It _does not_ include power conductors to
|
||
[[nfpa-70_100_definitions#Utilization Equipment.|utilization equipment]],
|
||
those are [[nfpa-70_100_definitions#Branch Circuit.|branch circuit]] conductors.

|
||
|
||
Today while (a peer) and I were walking, he asked
|
||
me what I thought of his qualities as an estimator.
|
||
I told him I think he has the right of it, that having beliefs
|
||
about what's correct that don't change just because
|
||
a senior says they should, is a good sign.
|
||
|
||
I can't remember now if I knew it before today,
|
||
but my relationship with Dale, my former manager,
|
||
while never "good", was much improved when I started
|
||
pushing back on his direction and feedback. I became
|
||
an estimator, where before I was just someone who
|
||
could estimate for him. He hated it, and let me know,
|
||
but I never felt more sure of my position.
|
||
|
||
Estimating is not a field where you get ahead
|
||
by being more technically skilled or efficient.
|
||
|
||
You distinguish yourself by convincing your superiors
|
||
that you understand the objective and how to achieve
|
||
it. The best estimators---as measured by compensation
|
||
package---are not doing takeoff, they're
|
||
telling other estimators what to take off and how.
|
||
|
||
Conquer your self-doubt. Tell your boss they're
|
||
wrong and stupid and they should feel bad. Profit.
