Most tradies can put together a shopping list but when it comes to estimating the expected labour time, things get more complicated. Profitable electrical contractors keep accurate records of productivity and regularly revise their labour units.
The labor unit method is a great starting point but a variety of factors need to be considered to accurately estimate. Here are some of them:
Time of day
Many electrical contractors are tempted to say yes to every job that comes their way, but this can be dangerous for the business. It’s important to understand the time required for each task and only take on jobs that you are capable of estimating accurately. This will ensure that you can deliver the best service for your clients and turn a profit. Inaccurate estimates can cost you more than just money. It can also cost you a client’s trust.
Professional electrical estimators can help you achieve accurate estimates and complete projects on time and within budget. They use specialized software to streamline calculations and automate estimation processes. They also collaborate with engineers and project managers to gather detailed information about the scope of work, which helps them minimize errors and align their estimates with the goals and requirements of the project.
Using labor units is one of the most common methods of estimating labour times. A labor unit is the estimated number of man hours needed to install a product or component. This estimate is based on the assumption that a skilled electrician can install the product in standard conditions. However, this assumption is not always accurate. Many factors can influence a labor unit, including weather, environmental conditions, and working hours.
While many electricians are able to look at a job and guesstimate the amount of hours it will take, this method is prone to errors. It’s better to use a specialized estimating tool, such as Countfire, to create an estimate. Using this software will allow you to import your takeoff quantities and automatically price items based on the prices you’ve used in previous estimates.
Temperature
Electrical estimators need to be familiar with local market rates for materials and labour, as well as any special installation conditions that could impact the cost of a project. These factors are taken into account by estimators to create estimates that are as accurate as possible and provide construction managers with a realistic assessment of the costs involved.
Creating an accurate estimate for an electrical job requires skill, and there are many ways to go wrong. Some mistakes that electrical estimators make include underestimating scope, using inaccurate data, and relying on a single estimating method. By avoiding these common errors, electricians can produce accurate and comprehensive estimates that help them win more jobs.
One of the most important aspects of electrical estimating is determining the amount of labor needed to install each item on an estimate. This can be difficult because labor times vary depending on the type of job, the building construction, and the electrical components used. To accurately determine the labor hours required to complete a job, electrical estimators must use the standard Labor Unit Manual available through most estimating software.
In addition to calculating the labor and material costs, an electrical estimate should also include overhead costs. This includes expenses like permits, temporary power, backhoe rentals, tools, ladders and scaffolding. It’s a good idea to include a budget cushion to cover unexpected job-related expenses. In addition, it’s important to add your profit margin and any markups you plan on applying.
Accessibility
The accessibility of the job site can significantly impact labour costs. For example, if the job requires an electrician to climb a ladder, or you have a lot of stairs, this will increase your labour costs. Another important factor is whether the job is located in a remote area or not. This will affect the amount of time it takes for your workers to get to the job site, and how much equipment they have to take with them.
The first step in estimating labour times is to determine the material and labor requirements for a project. This involves interpreting blueprints and technical drawings and conducting a quantity takeoff, which involves identifying and quantifying the quantities of cables, conduits, switches, outlets, and lighting fixtures. Estimators use their technical knowledge, detailed drawings, and specialized software to accurately assess the required materials. They also conduct research and gather accurate pricing information to calculate the cost of labor.
The design-build method of estimating is complex and requires a high level of expertise in construction, materials, labour and equipment. It is also highly dependent on weather conditions, which can affect productivity and lead to a significant variation in labour costs. For example, if the site is located in a rural area, the crews may be delayed by bad weather or poor road conditions.
Detailed plans
Electrical estimating is an integral part of the construction process. It enables contractors to determine how much materials and labor will cost for each project. This is important because the cost of materials can fluctuate throughout the year. It also ensures that the contractor will be able to turn a profit.
The first step in estimating is the takeoff, which consists of counting and measuring every electrical item needed for the project. This can be done manually or using estimating software. The next step is to transfer the items to a pricing sheet. For example, a duplex receptacle may consist of a box, plaster ring, switch, and cover. These components must be listed separately on the pricing sheet. Assemblies, such as single-pole switches, also require detailed breakdowns to include parts and labor. It’s also important to note any special requirements, such as the need for fire seals and other NEC-related labor.
Professional electrical estimators have a vast amount of industry experience and technical expertise, enabling them to accurately forecast costs for projects. They can help companies identify cost-saving opportunities and ensure that the project will stay within budgetary constraints. They can also assist with identifying any potential problems and ensure that the project will meet regulatory requirements. They can also provide a competitive edge by providing accurate estimates that align with the client’s needs.
