Laboratory Testing & Support
 
 

In construction, there is only one time to do it right - the first time.  GMT applies its specialized expertise in foundations, earthwork, construction materials, and construction procedures to help ensure the highest possible quality end product. GMT’s field staff performs quality assurance (QA) and quality control (QC) testing and inspections to verify compliance with project specifications.  But that's not all – the value is in the quality and commitment of our team members and the team approach we apply to every project to achieve success.  Each GMT field technician has been involved in certification training programs for proficiency in various test procedures and is in constant communication with our team of licensed professional engineers for immediate technical support.  GMT's field services enhance communication, documentation, trouble shooting, and problem solving on your project - a value which sets us apart from the competition.
