Scope of this Glossary
This glossary focuses on terms directly relevant to electrical estimating. It does not cover general electrical engineering principles or project management methodologies in detail.
Definition: Electrical Estimator
An Electrical Estimator is responsible for accurately forecasting the cost of electrical systems for construction projects. They analyze project documents, gather quotes from vendors, and prepare detailed cost estimates that inform bidding and budgeting decisions. For example, an Electrical Estimator would review architectural drawings, electrical specifications, and site conditions to determine the cost of wiring, lighting, and power distribution for a new building.
Direct Costs
Direct costs are expenses directly tied to specific project activities. These are easily traceable and quantifiable. For example, the cost of conduit, wire, and electrical boxes are direct costs.
Indirect Costs
Indirect costs are expenses necessary for the project but not directly attributable to a specific task. These are often overhead costs. For example, project management salaries, insurance, and temporary site power are indirect costs.
Labor Burden
Labor burden encompasses all costs associated with employing labor beyond the hourly wage. This includes payroll taxes, insurance, and benefits. For example, if an electrician’s hourly wage is $50, the labor burden might add an additional $25 per hour to cover these costs.
Material Takeoff
A material takeoff is a detailed list of all materials required for a project. It’s derived from project drawings and specifications. For example, a material takeoff for a lighting project would include the quantity and type of each light fixture, the amount of wire needed, and the number of connectors required.
Contingency
Contingency is an amount added to the estimate to cover unforeseen expenses or risks. It’s not for known costs. For example, a project might include a 5% contingency to account for potential price increases in materials or unexpected site conditions.
Overhead
Overhead represents the general costs of running a business, not directly tied to a specific project. These are ongoing expenses. For example, office rent, utilities, and administrative salaries are overhead costs.
Markup
Markup is the amount added to the estimated cost to cover profit and risk. It’s the difference between cost and selling price. For example, an estimator might add a 10% markup to the total estimated cost to ensure a profitable project.
Escalation
Escalation is an adjustment to the estimated cost to account for future price increases due to inflation or market conditions. It’s a projection of future costs. For example, an estimator might include a 3% annual escalation factor for material prices in a multi-year project.
Value Engineering
Value engineering is a systematic process to identify and eliminate unnecessary costs without sacrificing quality or functionality. It seeks to optimize project value. For example, an estimator might suggest using a less expensive but equally effective type of conduit to reduce material costs.
RFI (Request for Information)
An RFI is a formal request for clarification or additional information about project documents. It’s used to resolve ambiguities. For example, an estimator might submit an RFI to the project architect to clarify the type of lighting fixture required in a specific area.
Change Order
A change order is a written agreement to modify the original contract scope, cost, or schedule. It addresses changes requested by the client or unforeseen conditions. For example, if the client decides to add additional outlets after the initial estimate, a change order would be issued to cover the additional cost.
Bid Package
A bid package includes all the documents necessary for subcontractors to prepare their bids. This includes drawings, specifications, and instructions. For example, a bid package for an electrical subcontractor would include the electrical drawings, lighting schedules, and relevant sections of the project manual.
As-Built Drawings
As-built drawings are updated project drawings that reflect the actual installed conditions. They document any changes made during construction. For example, if the location of an electrical panel was changed during construction, the as-built drawings would reflect the new location.
Submittal
A submittal is a document submitted by the contractor to the architect or engineer for approval. It provides detailed information about materials or equipment. For example, a submittal for a lighting fixture would include the manufacturer’s specifications, performance data, and installation instructions.
Bill of Quantities (BOQ)
A Bill of Quantities (BOQ) is a comprehensive list of all items required for a construction project, with quantities and descriptions. It is often used in civil engineering and building projects. For example, a BOQ for an electrical installation would list the number of meters of cable, the number of light fittings, and the number of sockets.

The mistake that quietly kills candidates
Using vague language in your estimates undermines your credibility. Avoid generalities. Instead, use precise terminology and provide supporting data.
Use this phrase when presenting your estimate:
“Based on the material takeoff and current market prices, the estimated cost for wiring is [Dollar amount] with a contingency of [Percentage] to account for potential price fluctuations.”
FAQ
What is the difference between a direct cost and an indirect cost?
Direct costs are directly attributable to a specific project activity, such as the cost of materials and labor for installing conduit. Indirect costs, on the other hand, are necessary for the project but not directly tied to a specific task, such as project management salaries and site security. Understanding this distinction is crucial for accurate cost allocation.
How do I calculate labor burden?
Labor burden is calculated by adding up all the costs associated with employing labor beyond the hourly wage, including payroll taxes, insurance, and benefits. Divide this total cost by the number of labor hours to get the labor burden per hour. This ensures all labor-related expenses are accounted for in the estimate.
What is the purpose of a material takeoff?
A material takeoff is a detailed list of all materials required for a project, derived from project drawings and specifications. It ensures that all necessary materials are accounted for in the estimate, preventing shortages and cost overruns. For example, it includes the quantity and type of each light fixture, the amount of wire needed, and the number of connectors required.
How much contingency should I include in my estimate?
The amount of contingency depends on the project’s complexity and the level of uncertainty. A common practice is to include 5-10% for typical projects and higher for projects with significant risks. It’s important to document the rationale behind the chosen contingency percentage.
What is the difference between overhead and markup?
Overhead represents the general costs of running a business, such as office rent and administrative salaries, while markup is the amount added to the estimated cost to cover profit and risk. Overhead is a cost, while markup is a profit margin. Properly accounting for both is crucial for business sustainability.
How do I account for escalation in my estimate?
Escalation is accounted for by adjusting the estimated cost to reflect future price increases due to inflation or market conditions. This is typically done by applying an annual escalation factor to material and labor costs. For example, an estimator might include a 3% annual escalation factor for material prices in a multi-year project.
What is the role of value engineering in electrical estimating?
Value engineering is a systematic process to identify and eliminate unnecessary costs without sacrificing quality or functionality. It can involve suggesting alternative materials, methods, or designs that reduce costs while maintaining performance. For example, an estimator might suggest using a less expensive but equally effective type of conduit.
When should I submit an RFI?
You should submit an RFI whenever you need clarification or additional information about project documents. This helps resolve ambiguities and ensures that you are estimating based on accurate information. For example, an estimator might submit an RFI to clarify the type of lighting fixture required.
What is included in a bid package?
A bid package includes all the documents necessary for subcontractors to prepare their bids, such as drawings, specifications, and instructions. A well-prepared bid package ensures that subcontractors have the information they need to provide accurate and competitive bids.
What are as-built drawings used for?
As-built drawings are updated project drawings that reflect the actual installed conditions. They document any changes made during construction and serve as a valuable record for future maintenance and renovations. For example, if the location of an electrical panel was changed during construction, the as-built drawings would reflect the new location.
What is the purpose of a submittal?
A submittal is a document submitted by the contractor to the architect or engineer for approval, providing detailed information about materials or equipment. It ensures that the selected materials and equipment meet the project requirements and are approved before installation.
Why is it important to use standard terminology in electrical estimating?
Using standard terminology ensures clear communication and reduces the risk of misunderstandings. It allows all stakeholders to have a shared understanding of the project costs and scope. This is crucial for avoiding disputes and ensuring project success.
