Estimating material costs
The first step in the electrical estimating process is to select the right type of work to bid on. It is advisable to avoid bidding on electrical projects where one has limited experience. Without historical data to draw from, one is more likely to make mistakes during the estimating process, which could reduce profit margins.
To perform an electrical takeoff, one can work off the existing blueprints to create a comprehensive list of all the materials and quantities needed for the specific project. This list can then be used to calculate prices for each material and the total material and electrical costs. It is important to review the architectural drawings to understand working heights and elevations that will affect material pricing and equipment requirements.
Electrical estimating software can be a useful tool, providing an easier way to get the work done using a prebuilt system and methodology. Good electrical estimating software gives onscreen takeoff, estimating, and quoting all in one package, with features like auto-count and a full electrical labour and material database.
It is also possible to use a combination of Microsoft Word and Excel to create estimates, although this may be more time-consuming. It is important to ensure that the customer has a clear understanding of whether they are being given a quote or an estimate before starting any work. A quote is the exact price that the customer will pay for the services, while an estimate is subject to change.

Calculating labour costs
Understand the Scope of Work:
Firstly, review the architectural and electrical drawings to grasp the full scope of the project. This includes assessing working heights and elevations that will impact labour requirements and costs. Understand the general construction and technical details to identify potential discrepancies between drawings and specifications.
Determine Labour Requirements:
Based on the scope of work, determine how many electricians you will need and their specialisations. Consider the complexity of the project and the time it will take to complete. This will help you estimate the labour hours or days needed for the job.
Calculate Labour Rates:
Decide on the hourly or daily rates for the electricians involved. Consider factors such as experience, qualifications, and market rates for similar electrical services. You can use resources like salary surveys or industry reports to set competitive and profitable labour rates.
Account for Overhead Costs:
In addition to the direct labour costs, include overhead expenses such as travel, accommodation (if required), equipment rental, and any other operational costs associated with the job. These overhead costs are essential to consider when pricing your services accurately.
Add a Buffer for Unexpected Expenses:
It is always a good idea to include a buffer or contingency amount (e.g., 25%) in your labour costs to account for unexpected situations or expenses. This helps protect against potential losses and ensures that you can cover any additional costs that may arise during the project.
Use Electrical Estimating Software:
Consider utilising electrical estimating software, which can streamline the process and increase accuracy. These tools often provide features like auto-count, labour and material databases, and bid tracking. They can save time, reduce human error, and help you create fast, accurate estimates that impress clients and win more work.
Remember, providing accurate labour cost estimates is essential for maintaining client trust and ensuring the profitability of your electrical business.
