Atlas partnered with Caltrans to provide technical guidance and support in evaluating Stop-and-Go Ips for use in quality control and quality assurance roadway smoothness operations. Selected through a qualifications-based process, Atlas worked collaboratively with Caltrans and industry partners to assess equipment performance across a range of traffic conditions, including stop-and-start movement, braking and acceleration.ÌýÌý

Findings from these efforts informed updates to CT 387, Caltrans’ specification for profiler certification. Revisions addressed key areas such as survey speed variability and performance consistency under typical urban conditions. Atlas supported the implementation of these updates ahead of the 2024 Inertial Profiler Certification Program (IPCP) season.ÌýÌý

Through targeted task orders and focused coordination, the team helped Caltrans align certification standards with emerging technology while maintaining a commitment to safety, reliability and industry engagement.ÌýÌý

The SR 520 Bridge Replacement Program is a multibillion-dollar initiative by the Washington State Department of Transportation to enhance safety, reduce congestion, and improve mobility across .

Key components include the world’s longest floating bridge, HOV lanes, and a bicycle/pedestrian path, all designed with environmental stewardship and community engagement in mind.

This project will boost mobility between Seattle and the Eastside while setting new standards for sustainable infrastructure development. We’re providing extensive Quality Assurance (QA) testing and inspection services throughout the corridor.

Key Contributions:

• QA Testing and Inspection: Mobilization and daily operation of on-site testing laboratories for soils, aggregates, and concrete at each project site. QA data management and reporting, supported by multiple teams of inspectors and testers.

• Pontoon Fabrication Plant Support: Atlas assisted with the start-up of the Quality Assurance Program, including the on-site satellite materials testing laboratory for high-strength concrete production and materials tracking documentation.

• Environmental and Materials Tracking: Atlas supports environmental stormwater management and materials tracking to ensure contract compliance.

Atlas ensures that all QA processes adhere to strict contractor schedules, providing round-the-clock support with 25 inspectors/testers working in 24/7 shifts to meet project milestones efficiently.

Specific Segments:

• SR 520 Pontoons Construction ($515 Million): Implemented Quality Assurance Program for high-strength concrete production and materials tracking.

• SR 520 Floating Bridge and Landings ($850 Million): Provided material laboratory testing services, special inspections, and multi-shift QC inspections.

• SR 520 Eastside Transit & HOV Project ($434 Million): Managed QA documentation, environmental work plans, and special inspections.

• SR 520 West Approach Bridge North ($264 Million): Provided initial environmental inspections and stormwater management.

The California High-Speed Rail (HSR) will revolutionize intercity travel by providing a faster, eco-friendly alternative to traditional transportation methods — eliminating an average of 3,500 tons of emissions annually across its 800-mile corridor.

Since January 2023, Atlas has been an integral part of an AECOM-led joint venture focused on implementing a Construction Quality Program. This program collects objective evidence to ensure and certify that all construction activities meet rigorous, federal-grade standards.

Key Contributions:

• Quality Management Plan Development: Atlas developed a Quality Management Plan aligned with ISO guidelines, incorporating key performance indicators to measure and evaluate the plan’s effectiveness.

• Quality Records Review: Our team thoroughly reviews construction quality records to certify compliance with contract requirements, ensuring all activities meet federal-grade standards.

• National Bridge Inspection Standards (NBIS) Inspection: Per FHWA standards, Atlas conducts on-site assessments and reviews quality inspection plans, RFC plans, and aerial photos. These detailed inspections help identify and address potential issues early on.
• Training Program: Atlas developed a training program for project staff focused on inspection and reporting processes. This initiative promoted a proactive approach to quality management, enhancing collaboration between the Authority and contractors while clarifying inspector roles and improving submission processes.

By collaborating closely with the California HSR Authority, Atlas proactively identifies and resolves deficiencies, maintaining the highest quality standards throughout each project phase.
