## Exterior Amenity vs. Site
|
||||||
|
|
||||||
|
Clarification from [[joel-jansen]] on [[pdi-breakdowns]],
|
||||||
|
provided while he reviews [[charlotte-south-end-hotel]].
|
||||||
|
|
||||||
|
![[exterior-amenity-vs-site.png]]
|
||||||
|
|
||||||
|
In the example above,
|
||||||
|
the uplights (XS-B, XS-G) should be [[pdi-breakdowns#Bid Item Site|Site]]
|
||||||
|
and the downlights (XR-D) should be [[pdi-breakdowns#Phase Back of House (BOH)|Back of House]].
|
||||||
|
==Only the enclosed area should be [[pdi-breakdowns#Area Exterior Amenity]].???==
|
||||||
|
|
||||||
|
In my takeoff I considered all of these Exterior Amenity,
|
||||||
|
though I'm not sure of my rationale, if I had any.

relevant to my [[units-takeoff]]/[[telecom-takeoff]]

for [[charlotte-south-end-hotel]].

I originally included EMT to the corridor for unit data drops.

Joel asked if I had seen a note in the drawings or otherwise requiring this.

I assumed I must have and went to find it, but stopped.
|

|
Recalling our discussion described in [[2026-03-25_08-14-59#"Free-Air Per Code"]],
|
||||||
|
I asked if it would even matter if I had.
|
||||||
|
Joel replied that it wouldn't,
|
||||||
|
and said that he would be swapping the assemblies
|
||||||
|
for their LV-bracket-only equivalents.

### Charlotte South End Hotel: ConEst Manager Review
|
||||||
|
|
||||||
|
[[conest-manager-review]] for [[charlotte-south-end-hotel]]
|
||||||
|
lead by [[josh-ford]],
|
||||||
|
attended by [[joel-jansen]] and myself.
|
||||||
|
|
||||||
|
#### Feeders
|
||||||
|
|
||||||
|
"MSA TO BUSDUCT"
|
||||||
|
needs more elbows: added.
|
||||||
|
Josh talked about necessary pullboxes,
|
||||||
|
but they were not added.
|
||||||
|
Josh stated the purpose of the closeout budget
|
||||||
|
is to prevent procurement from buying sizes
|
||||||
|
that may be chosen arbitrarily.
|
||||||
|
Added $5,000 to the budget.
|
||||||
|
|
||||||
|
Concern was expressed
|
||||||
|
that feeders up from Main Elec may need to be lengthened
|
||||||
|
to follow MSA TO BUSDUCT routing shown on floor plans.
|
||||||
|
|
||||||
|

> [!quote] Josh Ford
|
||||||
|
> I really like that your feeders are whole numbers, that's nice.
|
||||||
|
|
||||||
|
***
|
||||||
|
|
||||||
|
Generator control wiring missing?
|
||||||
|
may be taken off as mech?
|
||||||
|
not resolved, moved on?
|
||||||
|
|
||||||
|
#### Subfeeds
|
||||||
|
|
||||||
|
##### Unit Mech Connections
|
||||||
|
|
||||||
|
concern that subfeeds may be double dipping
|
||||||
|
suggest decreasing if tightening is needed
|
||||||
|
|
||||||
|
##### Routing
|
||||||
|
|
||||||
|
Josh complemented subfeed routing:
|
||||||
|
"That's taking pride in your work."
|
||||||
|
|
||||||
|
I have had hesitation that it was worth doing,
|
||||||
|
if someone told be it was a waste of time,
|
||||||
|
I would not have been inclined to disagree.
|
||||||
|
|
||||||
|
#### Units
|
||||||
|
|
||||||
|
Unit receptacles are shown controlled by master switch system.
|
||||||
|
I assumed full control (not half) so no made no consideration in takeoff.
|
||||||
|
Approved.
|
||||||
|
|
||||||
|
#### Lighting Control
|
||||||
|
|
||||||
|
DO NOT USE `System` "LV - Lighting Controls System" EVER
|
||||||
|
|
||||||
|
#### My Mistakes
|
||||||
|
|
||||||
|
> [!failure]
|
||||||
|
> Port Cochere was taken off as Exterior Amenity.
|
||||||
|
> Joel corrected this without telling me.
|
||||||
|
|
||||||
|
> [!failure]
|
||||||
|
> Missed unit occupancy sensors
|
||||||
|
|
||||||
|
#### Closeout
|
||||||
|
|
||||||
|
> [!quote] Josh Ford
|
||||||
|
> We're carrying material handling
|
||||||
|
> because we own fixtures and its a tall building
|
||||||
|
|
||||||
|
#### Labor Plan
|
||||||
|
|
||||||
|
\$1.41 per sf garage, expected ~\$1.00
|
||||||
|
|
||||||
|
***
|
||||||
|
|
||||||
|
0.182 hrs/sf seems incredibly high,
|
||||||
|
expected ~0.120.
|
||||||
|
|
||||||
|
#### Aside
|
||||||
|
|
||||||
|
> [!aside]
|
||||||

|
||||||

> "you only have one main switchboard?"

||||||
|
***
|
||||||
|
|
||||||
|
Josh found the answer to a question of scope
|
||||||
|
in the qualifications of Bid's proposal.
|
||||||
|
he said he did not immediately think to look for them
|
||||||
|
because they are rare of current proposals.
|
||||||
|
Apparently they are penalized by the Proposal Audit Scorecard.
|
||||||
|
"They wanted it uniform so they stopped putting qualifications on proposals"

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]] 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.
