Electrical Estimating Services Designed to Help You Win More Bids
In modern construction from complex commercial offices and specialized industrial plants to critical data centers and high-security healthcare facilities the electrical system is the essential, mission-critical lifeline. It represents one of the highest material and labor cost components and is strictly governed by rigorous safety standards. Errors in electrical estimating pose multi-layered risks: severe National Electrical Code (NEC) violations, costly change orders due to overlooked specialized equipment, and project delays stemming from material shortages in high-density areas.
Electrical Estimating requires deep, dedicated expertise beyond general construction knowledge. It demands meticulous quantification of every component (fittings, wire, cable, fixtures), adherence to the latest NEC requirements, and accurate labor factoring for complex, high-risk systems (low-voltage, medium-voltage, and specialized controls).
At Aris Estimating, we provide Definitive Electrical Estimating Services specializing in Division 26 (Electrical) and Division 27 (Communications). We partner with General Contractors, Electrical Subcontractors, Developers, and Engineers to deliver precise, audit-ready material takeoffs and labor unit estimates, ensuring your project is compliant, competitive, and highly profitable.
I. The Electrical Estimating Imperative: Complexity, Risk, and NEC Compliance
The challenge of electrical estimating lies in the immense volume of small, integrated components and the absolute necessity of compliance with strict, non-negotiable safety and performance codes.
A. Granular Quantification of Integrated Systems
We specialize in meticulous, assembly-based quantification across all major electrical system components, ensuring nothing is missed:
- Conduit and Raceway Systems: Precise linear foot takeoff of all conduit types (EMT, Rigid, PVC, flexible) by size, meticulously accounting for every fitting, elbow, coupling, connector, and hanger. Errors in fittings and hardware count often lead to the largest cost discrepancies in electrical bids.
- Wiring and Cable: Accurate measurement of all wire and cable (THHN, MC, armored) by gauge and conductor count. Our estimates account for mandatory voltage drops, necessary slack, and code-required conduit fill ratios factors that directly impact material volume and labor time.
- Fixtures, Devices, and Equipment: Itemized counts of lighting fixtures (including specialized ballasts and sensors), switches, receptacles, panels, busways, surge protection devices, and large equipment (e.g., motor control centers and main transformers).
- Grounding and Bonding Systems: Detailed takeoff of grounding rods, wire, exothermic connections, and bonding conductors required for syst
B. Specialized Systems: Low-Voltage vs. Medium/High-Voltage
We understand the cost difference between systems and handle them as distinct scopes:
| System Type | Typical Location/Component | Key Cost Driver in Estimating |
|---|---|---|
| Low-Voltage (Div. 27) | Communications, Data, Fire Alarm, Security, Audio/Visual. | Termination Labor (device and patch panel connections) and Cable Type/Category (CAT6, Fiber Optic, etc.). |
| Medium/High-Voltage (Div. 26) | Switchgear, Primary Feeders, Transformers, Distribution. | Equipment Cost (long lead-time items) and Specialized Installation Labor (rigging, splicing, testing). |
II. Strategic Deliverables for Absolute Electrical Control
Our estimate deliverables are engineered for immediate use in bidding, negotiation, and procurement, providing auditable certainty from start to finish.
A. The Comprehensive Data Package
- Itemized Bill of Materials (BOM) by Assembly (Excel): A highly detailed, filterable list of every component, often grouped into common assemblies (e.g., “Duplex Outlet Assembly”). This ensures Precision Procurement, eliminates waste, and guarantees material availability.
- Labor Unit Breakdown (NECA Standards): Detailed hours required for the installation of each activity and assembly. This is crucial for Bid Negotiation, providing the objective benchmark needed to vet subcontractor bids and manage field productivity goals.
- Visual Verification Takeoffs: Digital blueprints showing color-coded conduit runs, circuiting, fixture locations, and measured linear footage. This acts as a clear Installation Checklist for field foremen, minimizing errors and rework.
- Panel and Riser Schedules: Pre-calculated schedules showing necessary panel sizes, breaker types, bus configurations, and riser diagrams. This ensures Sizing Accuracy and mitigates costly change orders after equipment is ordered.
B. Adhering to the NEC and Labor Productivity
Every estimate is built with NEC compliance as a core standard. We ensure:
- Accurate Load Calculations: Estimates are based on validated load requirements, ensuring proper sizing of all distribution equipment (panels, transformers, feeders) to prevent code violations and system failure.
- Localized Labor Factoring: We apply verifiable labor unit standards (e.g., NECA, modified for regional productivity) that accurately reflect the time required to install specific components in challenging environments (e.g., high-ceiling runs, concrete embedment, or clean room installation).
III. Strategic Applications for Profitability and Risk Reduction
For Electrical Subcontractors
We deliver ultra-fast, highly accurate takeoffs that free your in-house team to focus on securing quotes, optimizing project management, and sharpening the final bid presentation. Our precision guarantees you hit the lowest possible profitable price point without the risk of missing critical scope components.
For General Contractors and Developers
Our independent electrical estimate serves as the essential unbiased benchmark required to perform effective bid leveling. We ensure that all electrical subcontractor bids cover the full, identical scope and provide the necessary detail to negotiate the best possible contract price, protecting the overall project budget.
