The Hampton Roads Bridge Tunnel Expansion Project is the largest highway construction project in Virginia’s history. This project widens the current four-lane segments along nearly 10 miles of the I-64 corridor in Norfolk and Hampton and includes the construction of new twin tunnels across the harbor by TBM.
Gall Zeidler Consultants (GZ) is providing full-time inspectors to the Quality Control team, headed by KCI Technologies Inc. These inspectors cover different quality control disciplines amongst all active construction areas throughout the Hampton Roads Bridge Tunnel Expansion Project, including the South Island Tri-Cell Shaft, North Island Slurry Walls, and North and South MOT. Some of the operations being monitored by GZ include jet grouting, shotcrete and surface improvement, waterproofing installation, reinforcing steel installation in sub/superstructures, concrete placement in substructures, and beam installation.
