Pasadena-based Tetra Tech Inc. has reeled in a pair of contracts in recent weeks, one of which is near its back yard.

The local contract, announced March 24, was awarded by the Los Angeles Harbor Department for a three-year term to provide environmental and technical services for the Port of Los Angeles. The port is amid a multi-year $2.6 billion infrastructure investment program.

Under the contract, Tetra Tech scientists, engineers, and technical specialists will provide environmental site assessment and restoration services for sites across the port’s 7,500 acres of land and 43 miles of waterfront. Tasks are expected to include stormwater and groundwater monitoring and reporting, compliance assessments, remedial investigations, and designing and carrying out plans to restore impacted properties.

“Tetra Tech has provided environmental science and engineering solutions to support the Port of Los Angeles in its groundbreaking environmental initiatives and commitment to responsibly managing resources for more than 30 years,” Roger Argus, Tetra Tech’s new chief executive, said in the announcement. “We look forward to continuing to use our ‘leading with science’ approach to support POLA in facilitating global trade while protecting human health and the environment.”

Argus took the helm of the environmental, engineering and tech consulting firm in February as part of a planned leadership transition. Former Chief Executive Dan Batrack had served 20 years in the post before transitioning in February to executive chairman.

Enterprise tech services contract

The other contract work is more far-ranging geographically.

The company announced March 17 that the Defense Logistics Agency awarded it a $14 million task order under an enterprise technology services contract to provide information and operational technology support for its global supply chain modernization program. The agency procures military spare parts, fuel, food, clothing and other supplies for combat forces around the globe.

Tetra Tech will provide expertise to sustain, modernize, and transition automated material handling equipment systems; add in augmented reality and voice tech systems; and support upgrades to the agency’s warehouse systems.

“We look forward to continuing to use our industry-leading IT, (operations technology) and cybersecurity expertise to secure the supply chain infrastructure that supports defense readiness worldwide,” Argus said.
