An electrical system layout includes the complete installation process of the electrical components such as circuits, sockets, junction boxes, wires, and various other components. The placing of cable routes to ensure safety and various other factors have made numerous hurdles for electrical workers to win bids.

The market competition is increasing day by day and the requirement for the best electrical process documentation to win bids is difficult for electrical work. Contractors and electrical engineers need to submit accurate estimations and high-quality proposals for project-winning outcomes. This is where our Electrical estimating services play the role, with the most accurate and cost-effective estimations for your electrical project.

To estimate electrical work means a thorough analysis of electrical project specifications with the help of high-quality software and previous similar project evaluations to come up with a detailed report of the material, components, tools, fixtures, labor, and more estimations based on quantity and cost required for the electrical project.

Best Way to Estimate Electrical Work

There are various methods involved in providing the best estimate for the electrical project. These ways include per-point method, labor unit, prebuild method, design and construct, guestimating, and various other methods for the most accurate calculation of the material layout of the Electrical work.

  • Per-point Method

The Per-Point method involves assigning a financial fixture a point. And then the total number of points would define the project’s estimated cost.

Let us suppose you have assigned 100$ as 1 point and your project is constructed of 1000 points. Then your entire project is estimated to cost about 100,000$.

This method is used for smaller-scale projects and is more open for errors and inaccuracy. However, for an experienced expert who has worked on similar projects, would become easy to make precise estimations.

  • Labor unit method

The labor method is used to estimate the division of labor and also the budget required to manage labor for the construction or electrical work. It includes assigning a job a fixture, depending on the labor hourly rate. Let us suppose a fixture or a point is 30$ and a job may require 1 point while another may require 4 points depending upon the time and outcome of the job. This is how various projects are estimated and the labor budget estimation is made for the project.

  • Preliminary estimate

It is an informal estimate that is used to calculate the cost and budget of the project. This estimation is required way before the start of the project to see whether they can afford the project.  It is used for large-scale project estimations where the client may require the cost evaluation even before the project design and documentation are achieved.

  • Design and construct

The design and build method involves the designer providing the design himself for the construction project and carrying out the process execution. Experienced contractors accomplish such jobs under a single project to ensure collaboration throughout the process.

  • Guesstimate

Guestimating is an arbitrary approximation that is given for a project. It defines project evaluation and without the presence of the requirements. The estimation is no way near to being reliable and accurate. It can be used for small-scale projects in determining the cost that may be required for the project.

  • Estimating Softwares

Various estimating software can be used to make the most accurate estimations. Moreover, their outcomes can compared to come up with more efficacious results. These include PlanSwift, BuilderTrend, ProEst, ClearEstimate, RsBeam, BlueBeam, and various other highly developed estimating software.

The accurate results are calculated from the analogous measurements obtained from the software to come up with precise and cost-effective results.

How to Estimate Residential Electrical Work

A residential project is easy to achieve. However, if accurate estimations are not made, it can lead to various irrelevant expenses and delays in project completion. It is therefore required to carefully analyze the project requirements to come up with an extremely authentic estimate of wire, circuits, capacitors, resistors, sockets, and various other tools, delivering excellence in the project documentation.

Whether it’s a single-unit residential house or a multiple-family residential, accuracy in estimates must never be compromised. The electrical estimating task of the houses includes the complete electrical wiring and component arrangement of the interior and exterior electrical wiring.

  • Pre-Bid Planning and Review

Pre-bid planning is the nascent stage of electrical estimation which includes the coordination between the project owner and the contractors to discuss the project requirements and resources.

Contractors carefully consider all the necessary factors and the budget provided for electrical work is used to evaluate how the project will look after the completion, through the specifications provided.

  • Review the Drawings

In this phase, all the architectural and structural drawings are reviewed to estimate the electrical requirements of the project, the labor, and various other endeavors and observed. Determining which components and tools will be required for the project to come up with a detailed estimation report for project documentation.

  • Material Takeoff

After all the components and the material used have been extracted from the project. The components and tools are evaluated on the basis of the quantitative analysis. Furthermore, each material is listed with the cost, considering market trends with thorough estimation. A detailed report is made which is beneficial for project success.

  • Calculate Labor Costs

Now the contractor calculates the labor cost considering the hourly rates of the labor and also estimates the time that would be required for the electrical project completion. It will also calculate the pay of the subcontractor for the completion of the project. This will clarify the project with an easily manageable project documentation.

How to Estimate Commercial Electrical Work

Commercial electrical projects are more challenging to achieve than residential house projects. Commercial electrical work includes high-quality wire installations, escalators, elevators, heavy lighting, motors, generators, and various other components.

Proper electrical estimation of the construction project is necessary to achieve a reliable outcome. The installations must be up to the standards to ensure current stability and a secure environment.

Review the Electrical Plans

For the commencing of the electrical project and quantification of the components, some considerations are made.

Quality of the material: It includes the brand and the quality of the material being used because choosing a high-quality and durable material is extremely necessary to ensure safety for various purposes in a commercial electrical project.

  • Electrical System Design

How the electrical system is designed, keeping in mind the layout and cable routes of the commercial building are important for a successful electrical project.

  • Electrical Code Compliance

Using the established electrical code compliance for the thorough design and installation of the electrical components.

  • Safety Concerns

Considering all the safety concerns and the quality and size of wires used for the project. Taking all the necessary safety measures, including regular inspections and electrical hazard analysis.

Estimate Cost of Materials

The cost of accomplishing electrical work for a commercial building could be relative to the geographical location and the market trends. The accurate cost of the wiring, components, and materials such as circuits, transformers, and more are estimated on prices for winning project proposals.

Calculate Hourly Labor Cost

After a comprehensive estimation report is made in an Excel sheet format report than the amount of labor and jobs are specified. Labor cost is evaluated considering the labor hourly rate in the market.

Additionally, the electricians involved are also estimated on the basis of the project timeline for effective results. A commercial project requires regular inspections, avoiding overloading circuits, electrical hazard analysis, cord inspection, and plugs, and various other measures to ensure a safe electrical environment.

Add Overhead and Profit

After all the necessary cost estimations and quantity analysis is made of the electrical project then the profits are calculated within the scope of market competition and highly affordable rates are ensured for bid-winning proposals.

A commercial electrical wiring layout may require more expenses and most of the owners are willing to spend for extensively secure results. Safety is never compromised and this is what electrical estimating ensures its clients.
