Once you have all the pricing information you need, it’s time to build your electrical estimate. This can be done with a spreadsheet, an expert estimating software or by hand. Whichever method you choose, it’s important to include a breakdown of all the necessary supplies and expenses, as well as a detailed description of the scope of work.
2. Know Your Tools
An electrical estimator is a vital role that helps determine the necessary resources to complete projects within budget. They must be able to read blueprints, understand construction codes, and have the ability to accurately analyze each component of the job. This includes knowing the proper materials to use, labor rates, and overhead costs. Additionally, it is important for electrical estimators to stay up-to-date on industry standards, as these are constantly changing.
Using software tools for electronic plan takeoff reduces errors and increases accuracy. These tools allow you to highlight and count symbols, measure distances, and create takeoff reports that can be used as a basis for your estimate. This is an essential step for accurate electrical estimating, and it is best done digitally to prevent mistakes.
Another critical part of accurate electrical estimating is the ability to assign a dollar value to each point. This can be done through per-point, unit, or labor hour methods. It is also important to know which estimating method will be best for the project at hand. For example, if the project requires a lot of electrical wires, it may be better to use the per-point method, which will ensure that all of the points are assigned the correct price.
A final aspect of good electrical estimating is having the right equipment and tools on hand. This includes everything from a basic calculator to professional estimating software. Using these tools will help you accurately calculate key equations, including voltage drops, electrical load, and fault currents. It will also help you create a comprehensive itemized list of all expenses and supplies to include in your bid. This will give your client transparency and a clear understanding of what the project will entail.
3. Know Your Materials
When it comes to electrical estimates, the right materials are vital for the job. Without accurate material cost analysis, it can be impossible to determine a realistic price for the work you’ll perform. This includes items like wires, circuit breakers and switches, panels, electrical tape, ductwork, conduits, lighting fixtures, batteries, etc. Using the right estimating software can help you keep track of all the items you need to order from your suppliers.
In order to create an accurate estimate, you must complete a detailed material takeoff for each job. This process takes each item on the blueprint and enters them into your estimating software as line items. You can then follow a workflow that generates purchase orders to order each required material, and even include shipping locations, vendor information and special instructions for the project manager. This way, you’re able to avoid costly mistakes while streamlining the estimating process for each new project.
A good electrician knows the difference between a quote and an estimate, and understands how each can impact their business. A quote is an offer to customers, whereas an estimate is a proposal that includes all possible costs. The best electricians know that a well-written and detailed estimate is a valuable tool for both the client and their own business.
When creating an estimate, the best electricians are careful to consider every aspect of the project, including labor, equipment and materials. They also keep up to date on technology advancements and have a strong understanding of industry standards and practices. As a result, they’re able to create fast and accurate estimates that increase customer trust and win more projects.
4. Know Your Labor
When it comes to electrical estimations, knowing your labor is crucial. It takes a deep analysis of the project requirements and thorough calculation to accurately estimate both material costs and labor. Quality estimates help guarantee financial success and client satisfaction without frustrating overcharges or costly change orders.
A skilled electrical estimator starts with a detailed review of the project specifications and drawings to fully understand what’s involved. This includes reviewing all potential wiring needs, such as whether the work will be new construction or rewiring existing systems. It’s also important to determine if the job will require any special considerations, like emergency or backup systems, or energy efficiency upgrades.
Next, a skilled electrical estimator performs a detailed plan takeoff using specialized software. This allows them to identify and quantify all of the required materials, including wire lengths, fuses, sensors, power outlets, switches, and lighting fixtures. They’ll then add in the appropriate overhead and profit margin to complete the estimate.
The final step in accurate electrical estimating is completing accuracy checks to ensure all necessary information has been included. This includes the total job cost, subcontractors’ rates, and the profit margin. This helps to avoid mistakes that can derail projects, such as underestimating material costs or labor hours, or underestimating the profit margin. With Countfire, these accuracy checks are built right in, from the initial project assessment through to the final estimate.

5. Know Your Overhead
A common mistake electrical estimators make is neglecting to account for overhead expenses. For example, if an estimate doesn’t include the cost of renting equipment or covering labor costs for additional employees hired to handle a job’s complexity, it can undervalue the work and negatively impact profitability. This oversight can also lead to unforeseen project changes and budget issues.
Additionally, estimating without accounting for variable prices and supply chain disruptions is another big mistake that can have negative financial consequences. Prices for materials such as copper, aluminum and steel can shift rapidly due to a variety of factors. For this reason, it’s crucial to remain apprised of pricing trends and incorporate them into estimates for maximum accuracy.
