Environmental challenges can quickly disrupt bridge rehabilitation and transportation infrastructure projects. Unexpected contaminated soil, hazardous materials, or regulatory requirements can delay construction, increase costs, and create safety risks if they are not addressed quickly.
During a $24 million bridge rehabilitation project for a major state transportation authority, contaminated soil discovered beneath the bridge’s northern approach required immediate environmental investigation, remediation planning, hazardous waste characterization, and regulatory coordination before construction could safely continue.
EBI partnered with the project’s general contractor to provide comprehensive environmental consulting services throughout the project. By integrating site investigation, environmental remediation, contaminated soil management, hazardous waste disposal, air monitoring, and construction environmental oversight, EBI helped keep the project moving while protecting workers, the public, and the surrounding environment.

Results at a Glance
background
As excavation began, environmental investigations identified multiple contaminants exceeding state and federal regulatory standards. Construction activities could not proceed until contaminated materials were properly investigated, characterized, and managed.
Like many aging transportation infrastructure projects, historic fill materials and legacy contamination presented environmental risks that required specialized remediation planning, regulatory coordination, and ongoing field oversight.
The Challenge
Environmental investigations identified several complex issues, including:
- Asbestos-containing material (ACM)
- Petroleum-impacted soil
- Elevated concentrations of regulated metals
- Lead concentrations that classified portions of excavated soil as characteristic hazardous waste
These conditions required an integrated environmental solution that would:
- Protect worker health and public safety
- Maintain compliance with state and federal environmental regulations
- Properly characterize and manage contaminated materials
- Minimize disruption to the construction schedule
- Coordinate documentation and communication with environmental regulators
EBI's Solution
Working closely with the general contractor and state environmental agencies, EBI evaluated both in-situ and ex-situ remediation alternatives, coordinated required regulatory notifications, and prepared the environmental documentation necessary to support safe excavation, contaminated soil management, and hazardous waste disposal.
Services Provided:
- Environmental Site Investigation
- Environmental Remediation
- Excavated Materials Management
- Hazardous Waste Characterization
- Environmental Regulatory Coordination
- Air Monitoring
- Construction Environmental Oversight
- Health and Safety Planning
- Soil Characterization
- Environmental Compliance Support
EBI prepared and implemented a comprehensive suite of project-specific environmental plans, including:
- Excavated Materials Management Plan
- Health and Safety Plan (HASP)
- Soil Pre-Characterization Plan
- Release Abatement Measure (RAM) Plan
