The island has a quality control laboratory responsible for ensuring that all materials and specifications for road works meet minimum standards as stipulated in technical documentation. The laboratory's overall objective is to optimize and improve the quality of procedures and materials for road works.
The laboratory is run by the Technical Service for Roads and conducts quality control testing not only on services offered by the Department for Roads, but also on those provided by all other Technical Service Offices run by the Council of Tenerife, as well as town halls upon request. All testing is carried out by highly-experienced personnel who periodically attend courses to keep up-to-date with the latest technologies.
