Did you know that nearly 70% of construction projects go over budget due to inaccurate estimates? That’s right— one miscalculation can throw off the entire plan leading to financial losses, delays, and frustrated clients.
For general contractors, getting the estimate right is not just important; it’s essential for survival in the industry. If you miss one detail, the whole picture can fall apart. And let’s be honest, no one wants to deliver bad news halfway through a project because “Oops, we forgot to account for that.”
In this guide, we’ll break down the steps, explain the must-haves, and share practical tips to help you nail your next estimate.
As a general contractor, you’ve likely experienced how crucial a good estimate is to the success of a project. A detailed estimate helps you:
On the flip side, poor estimates can lead to everything from financial losses to strained client relationships.
Overestimating might lose you the job while underestimating can drain resources and damage your reputation; nailing down an accurate process is non-negotiable.
A solid construction estimate isn’t just about listing numbers; it’s about covering every aspect of a project’s cost. Here are the critical elements every general contractor should include:
These are expenses directly tied to the physical work of the project. Think materials, labour, and equipment costs. Whether it’s bricks and cement or skilled tradespeople, direct costs often make up the bulk of your estimate.
Also called overheads, these include expenses like office rent, administrative salaries, and utilities. Even though they’re not specific to a single project, they still need to be factored into every estimate.
No project is without its risks. Contingency funds provide a financial cushion for unforeseen issues, like design changes or material price hikes.
This is your reward for managing the project and taking on its risks. The margin you choose should balance competitiveness with profitability.
Before you start crunching numbers, study the project’s blueprints, specifications, and contracts thoroughly. This helps you understand the scope of work, identify potential challenges, and set realistic expectations.
This step involves measuring and listing every material, piece of equipment, and task needed for the project. For instance, if you’re building a deck, you’ll count boards, nails, and labour hours required for each stage.
Once you know what you need, calculate the costs for each item. Use supplier quotes, historical data, and industry standards to assign accurate prices to materials and labour.
Labour is often one of the most expensive parts of a project. Calculate the time required for each task and multiply it by the hourly wage of your workers. Don’t forget to consider factors like overtime or labour shortages.
Will you need to rent heavy machinery or tools? Include costs for rental, fuel, maintenance, or depreciation of owned equipment.
Remember to account for permits, project management fees, insurance, and other indirect expenses.
Typically, a contingency budget ranges between 5% and 15% of the project cost, depending on its complexity. It’s better to have a safety net than to be caught off guard.
The profit margin ensures your business remains financially healthy. Assess market trends, project risks, and operational costs to determine a competitive margin.
Review your estimate thoroughly to catch any errors or omissions. It’s also a good idea to have a second pair of eyes review your calculations.
