Estimator (Electrical Scope of Work)

 responsible for preparing complete, accurate, and competitive cost estimates for electrical construction projects. This includes performing detailed material take-offs, labor calculations, and vendor evaluations for power distribution, lighting, and low-voltage systems.

1. Technical Take-off & Quantity Surveying
Blueprint Analysis: Interpret electrical floor plans, one-line diagrams, riser diagrams, and site plans to identify all required components.
Material Quantification: Count and measure all electrical materials, including conduits, wiring/cables, cable trays, switchgears, panelboards, and lighting fixtures.
System Identification: Differentiate between various electrical systems such as Normal Power, Emergency/UPS Power, and Renewable Energy (Solar) integrations.
2. Power Distribution & Equipment
Load Calculation Review: Estimate costs for Main Distribution Panels (MDP), transformers, and sub-panels based on specified voltage and amperage requirements.
Circuiting: Calculate the total linear footage of branch piping and feeders, accounting for voltage drop and fill ratios.
3. Lighting & Control Systems
Fixture Counting: Perform detailed take-offs for indoor/outdoor lighting, emergency lights, and exit signs based on the lighting schedule.
Controls Integration: Estimate costs for dimming systems, occupancy sensors, and automated building management system (BMS) interfaces.
4. Auxiliary & Low Voltage Systems (ICT/Security)
Fire Alarm Systems: Quantify smoke detectors, manual pull stations, and control panels in compliance with fire codes.
Data & Telecom: Estimate structured cabling requirements, including CAT6/Fiber optics, racks, and patch panels.
Security: Scope out CCTV, access control, and public address (PA) system components.
5. Labor & Operational Costing
Labor Units: Assign labor hours to each task (e.g., hours per foot of conduit) based on project complexity and site conditions.
Indirect Costs: Account for specialized equipment rentals (scaffoldings, boom lifts), permits, and electrical testing/commissioning fees.
6. Vendor & Subcontractor Management
RFQs: Send out Requests for Quotations (RFQs) to electrical suppliers and specialized subcontractors (e.g., Lightning Protection or High Voltage specialists).
Bid Leveling: Compare multiple quotes to ensure they meet the technical specifications and "or-equal" requirements.
