What is CMT? Construction Materials Testing CMT is the testing of materials used to build new projects, add to existing projects, or amend existing construction projects.
The services involved in a comprehensive CMT process greatly depends on the project, the land, and the scope of services. Field testing CMT services take place at the site. Roadways, airports, utility projects, building developments: All typically involve CMT processes carried out by certified professionals.
What does Field Testing look for? Steel structures, retaining walls, and soil foundations are prime examples of construction that are evaluated during Field Testing. In instances where Field Testing is inconclusive or exploratory in nature , samples of various materials may be sent off for further lab testing. When Field Testing indicates further study is needed, Lab Testing is then recommended as the next phase of a comprehensive CMT regimen.
Laboratory testing is usually performed on an as-needed basis. Common lab-tested construction materials include:. Because it is critical for the viability and safety of a construction project. CMT can reveal any number of issues related to construction quality. It can highlight future risks, help classify a building site, and assist with engineering decisions.
Without CMT, engineers and builders may not know if the quality of the construction meets the requirements. Construction Materials Testing is also a regulatory requirement for most large-scale projects. To stay compliant, project managers must work with qualified, licensed CMT professionals before starting work.

Nondestructive testing NDT is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. The six most frequently used NDT methods are eddy-current , magnetic-particle , liquid penetrant , radiographic , ultrasonic , and visual testing. NDT methods rely upon use of electromagnetic radiation , sound and other signal conversions to examine a wide variety of articles metallic and non-metallic, food-product, artifacts and antiquities, infrastructure for integrity, composition, or condition with no alteration of the article undergoing examination. Visual inspection VT , the most commonly applied NDT method, is quite often enhanced by the use of magnification, borescopes, cameras, or other optical arrangements for direct or remote viewing. The internal structure of a sample can be examined for a volumetric inspection with penetrating radiation RT , such as X-rays , neutrons or gamma radiation. Sound waves are utilized in the case of ultrasonic testing UT , another volumetric NDT method — the mechanical signal sound being reflected by conditions in the test article and evaluated for amplitude and distance from the search unit transducer. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles either suspended in liquid or dry powder — fluorescent or colored that are applied to a part while it is magnetized, either continually or residually.
