The Importance of Quality Assurance in Construction Estimating

by Chris Hills in April 28th, 2023

As a construction estimator, it is crucial to ensure that every bid you submit to a general contractor is accurate, reliable, and meets the required quality standards. Quality assurance (QA) is an integral part of the construction cost estimating process, involving a series of systematic checks and reviews to prevent costly mistakes. In this blog post, we'll discuss the importance of QA in construction estimation, with a focus on construction cost estimating quantity checks in takeoffs, and material checks in estimating.

Why is QA important in construction estimation?

QA is essential in construction estimation for several reasons. Firstly, it helps you identify and prevent errors before they cause problems, reducing the risk of costly rework and delays. Secondly, it ensures that your estimates are accurate, reliable, and meet the required quality standards, increasing the likelihood of winning the bid and satisfying the general contractor's needs. Finally, QA enables you to comply with industry regulations and standards, which is crucial for construction projects that require adherence to safety codes and zoning requirements.

What are the consequences of poor QA in construction estimation?

Poor QA in construction estimation can have significant financial and reputational consequences for your business. Inaccurate estimates or incorrect material quantities can lead to costly overruns, lost profits, and damage to your reputation. As noted in a recent Correctional News article, "What Keeps Me Up at Night: Cost Estimating 2025," accurate cost estimation is essential for the success of any construction project. By implementing effective QA processes, you can prevent costly mistakes and ensure that your estimates meet industry standards. You can read more about the importance of accurate cost estimating in the Correctional News article here.

How can you implement effective QA in construction estimation?

Implementing effective QA in construction estimation involves several steps. Firstly, you need to define your quality standards and requirements. This will help you establish clear criteria for measuring the quality of your estimates. Next, you need to establish a QA process that includes regular checks and reviews at every stage of the construction cost estimating process. You should also invest in QA tools and technologies to help you automate and streamline your QA process, such as construction cost estimating software. Finally, you need to train your employees, including cost estimators, on QA best practices and ensure that everyone in your organization is committed to delivering high-quality estimates.

Importance of construction cost estimating quantity checks in takeoffs and material checks in estimating

Construction cost estimating quantity checks in takeoffs and material checks in estimating are critical components of effective QA in construction estimation. Quantity checks in takeoffs help ensure that your estimates are based on accurate measurements, reducing the risk of errors and rework. Material checks in estimating ensure that your estimates include the correct type and quantity of materials required for the project, reducing the risk of costly overruns and delays.


As a construction estimator, implementing effective QA in your construction cost estimating process is essential for preventing costly mistakes and ensuring that your bids meet the required quality standards. By performing construction cost estimating quantity checks in takeoffs and material checks in estimating, you can increase the accuracy and reliability of your estimates, reducing the risk of costly errors and delays.
