[ Electrical ]
Gear lead times, the low-voltage boundary, and a one-line that does not match the feeder schedule.
The number is set by distribution equipment you cannot get quickly and by scope that lives on the seam between Division 26, 27, and 28. Both risks are readable in the documents before the bid goes out.
The whole package, opened out.
Every document that governs a electrical bid, and the ones that hide something.

9 documents in this electrical package. 6 of them carry something that changes the number, and only one of those is a drawing.
Read the document, not the summary.
One extract from the electrical documents, at the scale an estimator reads it.
What it catches in electrical.
Each one cited to the document and page that proves it, so an estimator can verify it, price it, and approve the move.
- One-line contradicts the feeder scheduleDrawing E-101 · panel schedules
Conductor sizes on the riser diagram and the feeder schedule do not agree. The difference is copper, and copper is the bid.
SCOPE GAP - Lead time outruns the scheduleSpec 26 24 13 · project schedule
Switchgear quoted at a delivery date that lands after the milestone it feeds. The escalation and the liquidated damages both belong to whoever missed it.
SCHEDULE RISK - Division 27 / 28 written as "by others"Spec 26 05 00 §1.4
Structured cabling and fire alarm are excluded from Division 26 and never appear in their own sections. Pathways stay yours; the head-end does not.
SPLIT SCOPE - Temporary power carried in the front endSpec 01 51 00
General conditions assign temporary power and lighting to the electrical subcontractor. The invitation package treats it as general work.
UNPRICED SCOPE
Illustrative of the conditions this trade bids. Named pursuits, companies, and prices across this site are fictional.
Sector changes the clauses.
The same trade prices very differently depending on what is being built.
Data centersGenerator, UPS, and ATS sequences that determine the equipment list before any takeoff starts.
HealthcareEssential electrical branches and the transfer times the specification will not negotiate.
EducationLighting control narratives written in the spec and drawn nowhere.
IndustrialMotor schedules and process loads issued by addendum after the invitation.
Commercial officeBase building versus tenant scope split across two specification sections.
How ArosBid runs it.
Gear quotes arrive late and expire fast. ArosBid tracks every RFQ, chases the trades still missing coverage, and reconciles each quote against the schedule it has to hit.
