Concrete inspectors ensure correct concrete type, depth, mix, and reinforcements are used, and that final work meets code requirements. Education, experience, and certifications are required. Inspectors must understand curing strength and weather effects. Jobs are available in various industries and locations.
A concrete inspector performs a variety of tasks during construction projects. Inspectors verify that the correct type of concrete is used and that it is poured to the correct depth. They also check the concrete mix used, what reinforcements are needed and how weather conditions affected the job, such as how the concrete cured. An inspector is also responsible for ensuring that the final concrete work meets code requirements, which can be vital to the structural integrity of buildings and roads.
Education is required to prepare to become a concrete inspector. This training usually includes a basic knowledge of chemistry, math, and blueprint reading, as well as general inspection and building code requirements. Inspectors must also understand Occupational Safety and Health Administration (OSHA) regulations. Most employers require a minimum of a high school diploma and experience in that field, but a two-year degree and sometimes more education than that is the average requirement.
Certifications in concrete inspection can usually be obtained through various schools and commercial agencies. Having one of these certifications can offer better job opportunities in the industry. The American Concrete Institute (ACI) is a group that provides such accredited training. International certification programs are also available. Concrete inspectors often start out as concrete workers or finishers, allowing them to learn the entire process – and all facets included – of concrete work.
Inspectors must fully understand the ultimate cure strength of various concrete mixes. They should know the differences in how concrete cures depending on weather conditions, because heat, cold, and humidity affect how concrete cures or hardens. The thickness of poured concrete is also critical to its strength and the amount of weight it can safely support. Inspectors must measure the depth and ensure reinforcements are used as needed.
Working as a concrete inspector usually involves a considerable amount of time in the field on construction sites. Laboratory testing of concrete samples can also be performed by a concrete inspector or an independent laboratory. As construction site work takes place in all types of weather and in many different types of locations, inspectors must be prepared to perform in some adverse working conditions at times.
Many types of job opportunities are available for a concrete inspector. People in this position may work for government agencies, concrete supply companies, or commercial builders. Jobs may also be available at temporary agencies that specialize in the construction industry. Inspectors may also find opportunities to work in the cost estimating and engineering fields. In large cities, an inspector may find full-time laboratory work available.
