+### Charlotte South End Hotel: ConEst Manager Review
+

+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]
+> [[estimating-golf]] question:
+> "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.
