Electrical Construction Project Estimates: A Brief Guide

Every home, industrial facility, and commercial building needs a suitable energy source to light up and heat rooms and working areas and facilitate the operation of appliances and machinery. Electrical energy is one of the most popular solutions. In fact, in the US domestic sector alone, 1 in 4 homes is all-electric. If you plan to use electricity in your building and wonder about wiring costs, this article will help you out. It contains all you need to know to understand electrical construction project estimates.

What Are Electrical Construction Estimates?

Electrical construction estimates refer to estimated costs of installing electrical connections (wiring) that facilitate electricity supply. Estimation of costs is vital because it lets project owners and other stakeholders know the materials needed in electrical construction and the costs to be expected before the project kicks off.

Electrical Construction Estimation Techniques

The most common electrical project estimation techniques experts use include the following.

1.       Per-point technique

When an estimator chooses to use the per-point electrical estimation method, each fixture, such as a switch or sensor, is considered a "point" and gets a common dollar value. Therefore, for instance, if an estimator counts "A" number of points and each is assigned $"B" value, the entire project will cost an estimated $AB (A x B). Per-point is a quick project estimation technique that primarily relies on averaging. That means lows and highs are not taken into account. So it's safe to conclude a per-point method is a one-size-fits-all approach.

2.       Labor unit technique

 A labor unit refers to the amount of time a contractor takes to complete an electrical construction project. It covers the actual installation time and time needed to receive materials, take coffee breaks, study plans, mobilize, and assign tasks. Labor units differ depending on the construction company's productivity. But an estimator can determine a specific contractor's labor units by examining job cost records and comparing them with settled benchmarks. If you work with a reputable electrical contractor, they likely use project management software and update and revise their job cost records. Then, if that is true, your estimating experts will find it easier to provide estimates using recognized labor units.

3.       Guesstimating

As the name suggests, guesstimating utilizes a combination of calculations and guesswork. Since this technique mostly involves eyeballing a construction project and approximating the costs involved, it should be done by an experienced and skilled estimator who is familiar with common errors and project complexities.

Final Thought

There are many electrical construction estimation methods available for use today. However, you should let a skilled estimator pick and apply the right technique for your project for several reasons. First, experts have the experience, equipment, and estimating software required to optimize accuracy and consistency. Plus, they use tested methods to generate quotes and are less likely to make common mistakes that affect the entire construction project's progress and success.
