BRIDGES

From connecting cities to improving navigation and traffic, bridges are integral parts of our infrastructure. Braun Intertec has extensive bridge experience that ranges from providing services for pedestrian structures to expansive major highway bridges, including the new I-35W Bridge in Minneapolis. Our pre-construction bridge services include environmental assessments and geotechnical investigations, and when it comes to drilling, Braun Intertec has experience drilling on land and over water, including advancing borings through 60 feet of water and 240 feet of soil to help with the foundation design of the Four Bears Bridge in North Dakota. During construction, we can also assist with air and dust monitoring, materials testing, environmental construction monitoring and oversight, and geotechnical engineering for foundation design.

Some of our bridge-specific services include:

• Environmental management plans for issues such as contaminated soils and Storm Water Pollution Prevention
• Pre-condition surveys and vibration monitoring
• Dynamic monitoring of deep foundation systems
• Bearing capacity evaluation for deep and shallow foundations for bridges and walls
• Design phase load testing
• Quality control testing
