Build the electrical grounding and bonding takeoff review record
Read one-line diagrams, grounding details, equipment schedules, plans, and specifications together. List service grounding, separately derived systems, building steel, water piping, concrete electrodes, ground rings, and equipment connections shown. Give every path a source reference.
Use the electrical feeder takeoff review as a related control. Keep this review tied to its own source population and cost lines.
Check quantities and scope boundaries
Measure conductors and count clamps, lugs, bars, bushings, jumpers, test wells, and connection points by the documented material and size. Keep lightning protection, telecommunications bonding, and utility work in separate scope groups.
AACE recommended practices provide general estimating references. The controlled project documents and approved estimate basis govern this review.

Reconcile the package before release
Reconcile grounding items with service equipment, transformers, generators, distribution gear, feeders, and site electrical work. Confirm excavation, concrete coordination, testing, labeling, and connection responsibility before the estimate moves to review. Record unresolved assignments in the construction scope gap matrix and preserve the approved disposition with the estimate revision.
