What Is Operational Efficiency?

At its core, operational efficiency is the ability of a construction company to complete projects in the most cost-effective and time-effective way, without sacrificing quality.

But before you start increasing your operational efficiency, you need to know how efficient you already are. This means assessing the ratio between the output derived from the business and the input required to run business operations. 

By working to improve that ratio you are also directly working to improve your operational efficiency.

Some ways that construction businesses improve operational efficiency are:

• Reducing the idle time for their project teams
• Using task management software to:
  • streamline and automate manual tasks
  • reduce defects, change orders, and rework
  • Improve billing/invoicing rates
• Minimize waste
  
  

How to Calculate Your Operational Efficiency Ratio

You can calculate your business Operational Efficiency Ratio by using this formula:

What each variable in the formula mean?

Operational Efficiency Ratio Example:

To make the formula easier to comprehend, let's take the example of a carpentry company with $3 million in net sales per year.

• Operating expenses: $375,000 per year
• Cost of Construction: $1.5 million per year

Using the formula defined above, the operational efficiency ratio is:

• (375,000 + 1,500,000) ÷ 3,000,000 = 0.625 = 62.5%

What does 62.5% mean in this case?

Essentially, this means that 62.5% of the business's net sales are soaked up by operating costs. This is notably higher than the desired ratio of 50% or lower. 

When the input is high in relation to the output it suggests that a significant portion of the revenue is being used to cover the cost of planning and executing the projects, which impacts the overall profitability.

By breaking down the cost of construction and your operating expenses, you will have a better understanding of which elements dominate the costs outlined in the formula's numerator. 

Why Efficiency in Construction Is Crucial

Precision and attention to detail are critical due to the potential cascading effects of errors in measurements or placement. Diverse materials, each with specific installation requirements, demand a nuanced understanding and expertise. 

There are, however, many ways to increase the efficiency of your construction business and projects without sacrificing the precision and quality workmanship you deliver.

Alongside many other things on the to-do list,  project management is one of the most important parts of your construction project if you want to increase efficiency.

Inefficiencies in any part of the process can lead to delays, increased costs, and diminished overall quality of work. Operational efficiency in construction ensures that projects are completed on time, within budget, and to the satisfaction of clients. In the construction industry, where precision and attention to detail are crucial, optimizing operations becomes even more critical.

10 Ways You Can Maximise Your Construction Efficiency

Increasing your efficiency within each construction project directly boosts your business in many ways. From improving your cost management to completing projects quicker and helping your customer satisfaction in the construction industry, efficiency is often the missing secret sauce to help you grow.

But how exactly do you achieve it?

Here are 10 ways you can easily improve operational efficiency:

1. Comprehensive planning and scheduling

Effective planning and scheduling are foundational to construction site efficiency. By thoroughly mapping out the project timeline, allocating resources strategically, and considering potential obstacles, you can minimize delays and enhance overall productivity. 

Though a manual approach is still useful, you can improve your efficiency even further by utilizing software for contractors and other construction professionals. 

These construction management tools such as Buildbite offer useful time management tools and task management tools, providing robust scheduling to help you manage detailed plans, helping you and your team stay on track.
