US electrical estimating for data centers
A Division 26 estimate built around the bid documents.
Data Center Estimating prepares electrical takeoffs and bid build-ups for subcontractors bidding data center work. The estimate keeps quantities, scope boundaries, vendor inputs and assumptions visible for estimator review.
What comes back
Division 26 takeoff organized by system
Scope and interface schedule linked to the pack
Bid build-up ready for human estimator review
Services
Defined outputs for a live bid
Each engagement starts with the documents you have and ends with a reviewable deliverable.

| Requirement | Source | Action |
|---|---|---|
| MV feeders | SLD E-001 and specification 26 05 13 | Measure route and confirm terminations |
| UPS distribution | Equipment schedule and floor plan | Separate supply and install scope |
| Generator controls | Sequence of operation | Raise controls interface question |
Method
Estimate the system, then check the boundaries
Control the documents
Index the issued drawings, specifications, schedules, addenda and bid forms.
Measure and classify
Build quantities by system and keep drawing references beside the takeoff.
Review and reconcile
A human estimator checks scope, vendor inputs, allowances and exclusions before use.
Field notes and tools
Useful before the bid closes
How do EMT couplings and box connectors differ in a takeoff?
An electrical takeoff example counts EMT couplings and box connectors separately, with explicit route assumptions and a fitting-scope worksheet.
guideDoes a 4-inch square box designation identify depth and capacity?
A data center electrical takeoff worksheet separates nominal square-box size, depth, capacity, knockout pattern and cover scope using a sourced RACO example.
guideCan a closest metric cable size be treated as equal conductor area?
A cable takeoff cross-check distinguishes nominal area from a closest-size table and preserves the approved conductor and accessory scope.
guideDoes a conduit bend radius always mean centerline radius?
A conduit bend schedule records radius reference, outside diameter, product and approved geometry, with a labeled circular-geometry example.
guideDoes conduit trade size give the actual outside diameter?
A conduit takeoff cross-check separates trade size, outside diameter, product family and accessory scope without selecting conduit fill or hole sizes.
guideCan cable tray rung spacing be used to count external supports?
A cable tray takeoff worksheet separates rungs, straight sections, external supports and fitting details, with a synthetic quantity reconciliation.
