Third Party Verification

TTI is a preferred contractor of ISNetworld and Avetta.

These are global resources for connecting corporations with safe, reliable contractors and/or suppliers for capital-sensitive industries. Expert evaluations are conducted in several key areas, such as health and safety, including OSHA and client-specific standards, environment, insurance, procurement, regulatory information, risk, and corporate social responsibility. The comprehensive evaluation is an efficient and standardized way to meet our clients’ requirements while improving internal safety and information systems. TTI is proud to have A grade ratings due to our commitment to quality, environmental, health, and safety compliance.

TTI’s Commitment to EHS Excellence Recognized with ISNetworld RAVS Plus Status

We are also proud to announce that TTI has been awarded the prestigious RAVS Plus status on ISNetworld. This achievement places TTI among a select group of ISN contractors who have demonstrated active and effective implementation of safety programs. The auditor commended TTI’s employees for their insightful and accurate survey responses, demonstrating that our Environmental, Health, and Safety (EHS) practices are more than just written policies—they are integral to our daily operations. Based on a thorough assessment, the auditor recommended that TTI be awarded this distinguished status.

Achieving RAVS Plus status on ISNetworld is a powerful asset for TTI, reinforcing our credibility with both current and potential clients who value rigorous safety standards. This recognition underscores our dedication to ensuring that safety is a top priority across all our projects.

We want to extend our gratitude to our employees who consistently prioritize safety, attend trainings, wear appropriate PPE, stop unsafe work, and act as leaders in environmental health and safety. Their unwavering commitment makes this achievement possible and exemplifies the core values of TTI.

This recognition is a meaningful accomplishment, reflecting our dedication to EHS excellence. As we continue to evolve and grow, TTI remains committed to setting a high standard for EHS practices and contributing to safer work environments across all our projects.
