What does an estimator do?

Estimators collect and analyze data to estimate the money, materials, labor and time that a project requires, in addition to its associated overhead expenses. They often work at construction sites and collaborate with contractors, engineers, architects and clients. They make recommendations for how project managers can reduce costs. Estimators also maintain detailed records of both the estimated and actual costs throughout the entire project life cycle. Some of their other responsibilities might include:

  • Defining the scope of the project

  • Determining what information is necessary

  • Contacting suppliers and estimating costs

  • Analyzing and reviewing bids

  • Sending estimates to customers

  • Maintaining relationships with subcontractors and vendors

  • Communicating with trade partners about cost estimates and projected actual costs of projects

Estimator job requirements

There are several qualifications required to obtain a position as an estimator, including:


While some employers hire candidates who only have a high school diploma and work experience, many employers prefer to hire estimators who have a college degree. Some of the preferred majors for this profession include mathematics, civil engineering, construction science, construction management or applied science. A finance, economics or accounting degree can also be beneficial. The right education can prepare estimators for a specialized role in business information modeling (BIM), big data or visual estimating. 

Estimators require the knowledge to read blueprints, understand construction concepts and use computer programs that estimate costs and labor time for each stage of a project. Try to choose a degree program that teaches these concepts, offers resources for prospective estimators and supports the development of possible careers in this field. In addition, consider a program that can provide you with some estimation training.

When you're just beginning your career, it's important to work with people who are willing to teach you the basics of the profession. You may want to apply for a job as an estimator assistant and work with someone who already has extensive experience in the field. This position allows you to work directly under the supervision of an estimator and learn more about the various tasks estimators complete on a daily basis. You might also consider completing an internship where you can job shadow an estimator and perform various estimation tasks.

Another useful way to learn how to estimate project costs is by doing it yourself for smaller projects and slowly gaining the skills required to work on larger projects. Consider applying for part-time positions with an established contractor who can teach you the right tools to use. You may be able to earn valuable referrals from satisfied customers, which can benefit you when applying for more advanced positions. Employers often prefer estimators who have a few years of direct experience.

Job training

Employers that hire estimators train staff extensively before allowing them to work independently. Training can take place in the field and in the office, and its goal is to increase your knowledge of estimating software and your understanding of construction methods and procedures while also improving your familiarity with the company's estimating system. The training you complete may depend on your prospective employer. It may take a few months to potentially a year or longer.

While estimators aren't typically required to earn a certification to qualify for an estimator position, many employers, including civil engineering firms, prefer them. Earning a certification can help you prove your expertise. Consider earning one of the following certifications:

Certified Professional Estimator

The American Society of Professional Estimators (ASPE) offers the Certified Professional Estimator (CPE) for estimators with five or more years of experience. This certification program provides instruction on estimating and bid preparation principles, equipment costs, labor productivity, unit pricing and project management. To receive the certification, the ASPE requires you to submit an application, complete an orientation workshop, pass the written exam and submit a technical paper. To renew it, the organization also requires that you volunteer your expertise by reading or grading technical papers, proctoring exams or beta-testing new exams in your area of expertise.

Certified Estimating Professional 

The Association for the Advancement of Cost Estimating (AACE) International offers the Certified Estimating Professional (CEP) credential. The CEP verifies that an estimator has the vital expertise required to contribute to the valuation of projects by developing budgets and estimating resource requirements. To be eligible, candidates first earn eight years of industry-related experience or four years of experience and a four-year, industry-relevant degree. To earn the credential, AACE International requires you to complete an exam within the five-hour allotted time frame with a score of at least 70%. 

Certified Cost Estimator

The International Cost Estimating and Analysis Association (ICEAA) offers the Certified Cost Estimator (CCE) certification to verify an estimator's mastery of cost-estimating analysis. The program teaches candidates how to develop and estimate costs for capital projects using current industry standards. To apply, you need at least five years of relevant cost-related experience. The ICEAA also requires you to pass a two-part exam. To retain your certification, you can either retake the exam every five years or renew it through the association's points system.

Attention to detail

Minor changes to estimates can significantly impact the overall cost of a project, especially if they're related to the cost of individual materials needed in bulk or are associated with hourly labor costs. Estimators use their attention to detail to avoid oversights or errors. This can help them ensure accuracy and better manage a project's budget. When calculating costs, having excellent attention to detail allows them to be as accurate as possible.
