Our Estimating Methodology
Review the four stages of an electrical estimate: document control, measurement, pricing and scope review. Agree the inputs and checks for your project before work begins.
Scale Calibration
Every sheet verified against architectural dimension benchmarks.
CSI MasterFormat
Organized by standard Division 26, 27, and 28 classifications.
Labor Basis
Agree the labor source, productivity factors and wage rates.
Drawing-Based Takeoffs
Multi-step mathematical audit before any package is issued.
The 4-Stage Estimating Workflow
We treat estimating as a precision engineering task. Every project progresses through our systematic quality pipeline:
Document Baseline & Scale Calibration
Record issued drawings, specifications, schedules and addenda. Calibrate each scaled view against a stated dimension and check another dimension. Do not infer scale from a standard door width or measure a detail marked not to scale.
Digital Measurement & Schedule Reconciliation
Every switch, outlet, and lighting fixture is counted. Raceways and feeder lengths are traced with physical routing, vertical rises, and pull box allowances. Counts are reconciled against panel schedules and one-line diagrams.
Costing & Local Labor Adjustment
Extend quantities using dated supplier quotes or other agreed pricing inputs. State the labor-unit source and adjust installation hours for access, height, occupancy and phasing. Apply the contractor's wage and burden rates separately; a regional wage rate does not change the measured quantity or automatically establish productivity.
Quality Audit & Scope Letter Issuance
Agree who checks quantities, formula extensions and drawing revisions. Confirm the workbook, annotated PDFs and scope letter to be delivered, including assumptions, exclusions and the contractor's final review responsibilities.
Professional Scope Demarcation
Estimating and quantity takeoff support contractor bid preparation. They do not replace licensed electrical engineering, stamped design, permitting, inspections, or official code certification. The contractor and responsible design professionals must verify installation requirements with the authority having jurisdiction.
