This past weekend, we had the pleasure of celebrating our 25th anniversary with a private boat cruise along the Hudson River in New York City, joined by team members from both our Virginia and New York offices. The evening offered a perfect setting to mark this milestone — with fantastic weather, a beautiful sunset over the Manhattan skyline, and even a surprise fireworks display lighting up the river.

Since its founding in 2000, GZ has grown into a leading tunneling and underground engineering consultancy, recognized for its technical expertise, forward-thinking design solutions, and commitment to delivering complex infrastructure projects worldwide.

A heartfelt thank you to all employees, partners, and clients who have contributed to our success and continued growth over the years.

Here’s to the next 25 years of tunneling excellence!
