People Driven to Excellence

Employees of CLS are highly trained, dedicated and equipped with cutting edge technology. All employees are performance managed, with quality assurance and customer service as their primary goals, and guided by an experienced management team.

Best Practices

CLS leads the industry in sourcing, training and ongoing evaluation of its field technician force. Potential candidates are carefully screened and evaluated. CLS utilizes pre-employment drug screening, background checks and DMV reviews, as well as logical skills testing. Employees are randomly tested in accordance with 'the U.S. DOT, Research and Special Programs Administration (RSPA) Anti-Drug and Alcohol Misuse Prevention Plans.

Before any technician dons the CLS logo and travels to any site in our clearly identified fleet vehicles, he or she has received a comprehensive, ten-step training program consisting of both classroom tutoring and in-field, hands-on, monitored instruction.

All candidates must successfully complete written and field certification requirements before any independent locates are conducted; and each locator is required to be re-certified annually. This process ensures the level of expertise and professionalism that CLS is committed to maintain.

The CLS commitment to employee training, supervisor monitoring and follow-up exceeds the guidelines established by the National Utility Locating Contractors Association ( NULCA).
