🚧 Big day in Rancho Cordova! 🚧

Today marks two milestones for the team:

1. Our new CAT AP1055 paver is making its first production run.

2. We’re placing the bottom lift base course over the Full Depth Reclamation (FDR) section, moving this roadway one step closer to completion.

It’s always exciting to put new equipment to work, and even better when it’s helping move a project into the next phase. Great job to the paving crew getting after it and keeping things moving safely and efficiently.

The concrete lagging wall is complete at the Monte Rio Slide Repair project.

This has been a challenging hillside job with tight access, steep terrain, and work taking place right above the water. Big shoutout to Jose Carreon for doing a great job keeping this project moving safely and efficiently.

Great work by Jose and the entire crew on this phase of the job.

Hwy 101 in Ukiah is in full swing. Last night crews completed 62 yards of panel replacements. So far today they have set 900 linear feet of string line for the cable barrier pour and poured five ramps. Great progress from Gill and the team as work continues to move forward on the corridor.

Our crews recently put two custom solutions to work in the field during shoulder repair operations in Rancho Cordova.

The first was a 2-foot conversion for our 4-foot grinder, allowing crews to efficiently grind narrow shoulder sections and tight repair areas. The second was a custom skid steer mount fabricated by our shop team to help place new asphalt back into the ground area following the grinding operation.

Huge credit to both the shop and field crews for the innovation, fabrication, adjustments, and teamwork that went into making these setups work flawlessly in the field. This is the kind of problem solving that keeps production moving and helps our crews tackle work more efficiently every day. 👏

This Memorial Day, we pause to honor and remember the brave men and women who gave their lives in service to our country. 🇺🇸

A few weeks ago during Administrative Professionals Day, the Ghilotti Bros., Inc. team visited the Lone Sailor Memorial at Vista Point overlooking the Golden Gate Bridge.

The memorial holds special meaning to our company. In 2002, Mario Ghilotti and Henry Trione helped lead a fundraising campaign that raised $2–3 million entirely through private donations to build the memorial without government funding. The memorial honors members of the Navy, Marine Corps, Coast Guard, and Merchant Marine who passed through the Golden Gate on their way to service overseas.

GBI proudly donated the transportation, site work, foundation, and placement of the statue as part of that effort.

During the visit, our team also toured our current project at Vista Point, where we are helping improve the pedestrian pathway connection beneath the Golden Gate Bridge.

It was a meaningful day reflecting on both the history of the memorial and the importance of the work being done there today.

We will never forget those who made the ultimate sacrifice for our nation.

Multiple emergency water leak repairs completed at Kaiser San Rafael over the weekend. Crews worked through excavation, utility locating, and repairs to help keep the facility operating with minimal disruption.

Just another example of the team responding quickly, working safely, and getting the job done efficiently.

Happy National Safety Week!

We wrapped up Safety Week with one of our biannual Safety BBQs, a great way to bring the team together before the busy season ramps up.

No lost time incidents.
A strong start to the season.
And a team that continues to put safety first every day.
