My peer working on [[virginia-live-casino-and-hotel]]
|
|
pointed out the raised floor system used in the gaming area.
|
|
They asked if MC cable would be acceptable
|
|
for a mechanical connection in the area.
|
|
I replied that it would be acceptable
|
|
according to the [[nfpa-70_national-electric-code|NEC]],
|
|
but that I wouldn't be surprised
|
|
if it was specifically forbidden by the specifications.
|
|
In response they asked what _would_ be acceptable
|
|
assuming that MC cable was not.
|
|
I said immediately "EMT",
|
|
but corrected myself that PVC is also code permissible,
|
|
and they would need to rule it out before jumping to EMT.
|
|
|
|
I pointed out that this consideration was also relevant
|
|
to the floor boxes shown in the same area.
|
|
The heating designations built for the purpose by the previous estimator used PVC.
|
|
These were likely built from the existing floor box assemblies without modification.
|
|
|
|
At this, the estimator and I discussed wiring method selection in general.
|
|
For the jobs the two of us are assigned,
|
|
PVC is usually never acceptable except underground or in-slab,
|
|
however I explained that this is due to near universal specification,
|
|
not code compliance.
|
|
It is apparently typical of Florida jobs to run PVC
|
|
in most areas we would expect to use EMT,
|
|
even where in plain view.
|
|
|
|
The estimator said their strategy is to assume EMT assemblies
|
|
with the expectation that they may need to substitute them
|
|
following [[conest-senior-review]].
|
|
This is a [[heuristics|heuristic]]
|
|
in that it achieves an outcome acceptable to the estimator
|
|
despite being objectionable according to established[^1] [[conest|ConEst]] practice.
|
|
|
|
[^1]: As far as it can be said to be established...
|
|
|
|
Many seniors would expect that every estimator
|
|
know how to determine acceptable wiring method selection
|
|
for arbitrary construction considerations
|
|
given the project documents.
|
|
This is a deceptively naive expectation:---
|
|
|
|
What is acceptable according to the drawings and specifications
|
|
is frequently in contradiction with what was sold,
|
|
which is frequently in contradiction with what was _believed_ to be sold.
|
|
Determining "acceptability" then, is nontrivial for estimators
|
|
who, by all rights, ought not have to concern themselves
|
|
with resolving ambiguity so egregious it ought to be reprimanded.
