Electrical Estimating Services

The task of an Electrical Estimating Services estimator requires exceptional competence and precision. Your estimates are the foundation for how an electrical project will progress. Clients use your estimates to decide who will get the task or what can be accomplished within their budgetary constraints.

However, getting an accurate estimate is complex! Several factors are involved in making an estimate, and for certain projects, the work of electrical alone is enormous.

Your estimation process influences how precisely or readily you can generate estimates. Here, we examine several prevalent practices:

Methods for electrical estimating:

Below are some of the most common estimation techniques employed by electrical estimators. Each has its own set of benefits and drawbacks.

Computerized takeoff software can assist with any of the procedures described here. Its benefits include faster, more precise counting of takeoffs and simple collaboration and editing capabilities. Takeoff software may save you a great deal of time.

Per-point system:

According to the per-point technique, each fixture, whether a power outlet, a switch, a sensor, or anything else, is tallied as a “point” and given a standard dollar value. For instance, if you counted one thousand points and assigned each one a value of £100, your project estimate would be £100,000.

This estimation approach has abundant possibilities for an erroneous estimate, even though it is fast and straightforward. Consider, for example, the extent to which labor costs vary across occupations. If you allocate the same number of points to each fixture, there may be significant fluctuation.

Suppose that one project requires an additional wire to be routed between power points or that some plugs are single while others are double. In addition, the working circumstances may need an increase in labor – what if you were required to drill into concrete? Labor is the most prevalent issue with the per-point system since labor expenditures may rapidly exceed the budget. It might have a devastating effect on the profitability of any electricity firm.

This technique of Electrical Estimating Services is an average approach, which disregards extreme values. Variations in the estimation results are typical due to the approach’s “one size fits all” nature. This strategy may be effective if you construct a project with little change from previous ones.

Labour unit method:

The labor unit technique provides a monetary value (in units) to the amount of human labor needed to install each piece of hardware. The OECD defines a labor union as the average cost of employment per unit of output generated. It is the ratio between total labor expenses and actual output.

For instance, each labor unit may cost £75. A single outlet may need one labor unit to install, whereas a sensor may require three, and so on. The quotation is then calculated by multiplying the total increase in labor units by the value per unit.

In a recent piece, we discussed precisely determining labor expenses. Typically, labor units are determined using either a “shop average labor rate” or a “job average labor rate,” depending on the kind of task and its complexity.

The labor unit technique may be more precise than the per-point method since it allows a more reasonable calculation of the working circumstances. However, there are still several frequent hazards. For instance, individuals often neglect to incorporate “labor burden” expenses, the expenditures associated with your personnel unrelated to their activity. For instance, expenses such as sick leave, holiday pay, insurance, and taxes.

If you utilize the labor unit technique, you must also be cautious to differentiate between various working situations since here is where an erroneous estimate might result. For instance, the difference throughout labor between “easy” and “tough” situations might be considerable; thus, you wouldn’t want to undervalue your business by pricing your labor units too inexpensively.


Pre-construction is often referred to as the assembly estimation approach. It is a straightforward method for calculating takeoffs since it packages your components by incorporating the essential materials and establishing a unit price.

In electrical construction, there are several pieces with various components. For instance, power sockets consist of the PowerPoint, mounting bracket, and cable. It may be bundled into a single unit cost.

When estimating pre-builds or assembly, you may include a mix of materials and labor or separate chargeable items for materials and labor. Some contracts are referred to as rate schedules or unit pricing contracts. Typically, if you submit a bid for one of these, you must include your unit prices for pre-builds or assembly in the schedule.

The pre-build approach is susceptible to the same flaws as the per-point method (essentially a more intricate version of the per-point method). Common errors include erroneous labor estimation and failure to account for travel expenses.

Design and building:

In the design and build process, the electrical contractor is responsible for the design and the actual project execution. Typically, the client will supply a design brief outlining the project’s criteria, and the electrical contractor will prepare a more thorough design before beginning electrical construction.

It is among the most intricate estimation techniques. Typically, you will be required to operate within the client’s budget and offer precise building cost estimates. It contrasts with projects in which you submit a bid for a finished design.

The electrical estimator utilizing the design and build technique must have an extensive understanding of design methodology and construction, labor, materials, and equipment knowledge. The primary disadvantage of this approach is its complication, which leaves room for mistakes at every level.


There is a solid reason we saved this estimation approach for last – although estimation is still often utilized, it is the most error-prone. If you’ve seen a contractor who looks at a job and delivers a price on the spot, you’ve experienced an example of estimation.

Rather than carefully appraising the task at hand, estimations often rely on gut feelings. As a result, it might result in inaccurate estimates that need to account for the project’s complexity or overstate them.

A person with extensive expertise can look at a task and provide an accurate estimate, particularly if it is of the same sort and size they have been performing for years. However, we would not recommend this strategy to anybody who is not an expert since it is extremely prone to mistakes.

However, using the Electrical Estimating Services software, you may get an estimate based on the work you’ve previously completed for prior estimates. As soon as you input your takeoff amounts (with a single click! ), the software will automatically price as much of your estimate as feasible, depending on how you have previously priced goods.

It is a far more robust method for rapidly pricing and estimating a job based on real prior projects.

Last thoughts:

Estimating techniques are often determined by the expertise of the estimator and the Electrical Estimating Services approach selection. Additionally, speed, precision, and expertise play a significant role in this decision.

Overall, we recommend that all methods be founded on solid evidence. For instance, labor estimates should use the most accurate information on comparable tasks previously performed and the influence of working conditions on labor.
