Our Women+ members came together for another Kocktails (& Mocktails) with Kathryn, enjoying an afternoon of meaningful conversations, great company, and plenty of laughs. ✨

Over snacks and refreshments, members shared their perspectives by answering fun and thought-provoking questions, from the career advice they'd give their younger selves to the accomplishments they're most proud of, the skills they've picked up along the way, and even the workday essentials they can't live without.

The afternoon wrapped up with a spirited game of Headbands, proving that some of the best connections happen when we take time to learn, laugh, and celebrate one another.

Thank you to everyone who joined us and helped make this gathering such a memorable one! 💜

Happy National Intern Day! 👏

Today, we're celebrating the incredible interns spending their summer with Cahill. From the office to the jobsite, they've embraced every opportunity to learn, ask questions, and gain hands-on experience alongside our teams.

This summer, they've been building more than just industry knowledge. They've been developing new skills, making meaningful connections, and experiencing firsthand what it takes to bring projects to life.

We're proud to support the next generation of builders and grateful for the energy, curiosity, and fresh perspectives they bring each day. Thank you to our interns for your hard work and enthusiasm, and to our project teams and mentors for investing in their growth.

Technology is transforming the way we build, and our VDC/BIM team is leading the charge.

From 3D coordination models and drone imagery to thermal imaging and point cloud scanning, the team uses innovative tools to solve complex challenges before construction begins. As they put it, "We build the project digitally, so project teams can build them confidently and efficiently in real life."

What makes Cahill's VDC/BIM team especially impactful is the knowledge they bring across every project in our portfolio. "Solutions and lessons learned on one project can directly relate and benefit others in real time," helping project teams make smarter decisions from preconstruction through completion.

The visuals featured here showcase just a few examples of that work:
• 160 Freelon drone photography during the topping out ceremony
• Thermal drone imaging at 160 Freelon, capturing activity behind the scaffolding
• A coordinated Level 1 BIM model at 160 Freelon, where mechanical, electrical, plumbing, and fire protection systems were coordinated within tight building constraints
• A drone-captured point cloud mesh of Sunnydale Block 9
• Site elevation mapping generated from the same Block 9 drone scan

Beyond mastering software and technology, our VDC/BIM professionals develop deep expertise in building systems, construction methods, logistics, scheduling, and more. As they describe it, they're "a Digital Superintendent of sorts," bringing together technology and construction knowledge to help every project succeed.

Meet Raven, one of our former interns who has since joined Cahill full-time as a Project Engineer!

For Raven, stepping into the construction industry through Cahill's internship program was more than just gaining technical experience. It was about showing up each day with a positive attitude, taking initiative, and becoming a true member of the project team.

One experience stands out above the rest. During her internship, Raven led hot RFI and submittal discussions for two weeks during ICM and OAC meetings, collaborating directly with the design team while supporting the project team. It was a challenging opportunity that helped build her confidence and reinforced the value of stepping up when needed.

"As an intern, I learned that putting my best foot forward every day and having a great attitude helped me learn, grow, and feel like a real member of the project team."

That mindset carried into her transition to Project Engineer, where each day brings new opportunities to ask deeper questions, take on greater responsibility, and continue learning.

Her advice to future interns?

"Take initiative, meet new people, get out on the jobsite, ask questions, take lots of notes and photos, and most importantly, be in the moment and have fun."

When asked about her favorite part of working at Cahill, the answer was easy: the people.

"The teams at 750 Golden Gate and 850 Turk have made all the difference. Their support, collaboration, and energy have made this an incredible place to grow."

We're proud to see interns like Raven build meaningful careers at Cahill, and we can't wait to see where her journey takes her next.

We were pleased to host a group of middle school students from the nearby Asian Pacific American Community Center () for a tour of our Sunnydale Block 9 project—a 95-unit affordable housing development part of the Sunnydale HOPE SF () redevelopment effort.

Superintendent Tory Rollandi and Assistant Project Manager Mike Daly led the tour, offering students a firsthand look at the construction process and sharing insights into careers in the industry.

Opportunities like this help us stay connected to our community, spark curiosity, and inspire the next generation of builders. Thank you to our team for investing their time and expertise in these future professionals.

Cahill Paintball 2026 was a huge success!

With perfect weather and high energy all day long, it was the perfect setting for some friendly competition. It was great to see everyone's competitive spirit come to life as teams strategized, defended, and worked together through every round.

A special MVP shoutout goes to Matt Dennig and his daughter, Savannah, who proved to be the most formidable duo of the day. Thanks to everyone who came out and made it such a fun event!

On Monday, Governor Newsom signed landmark housing legislation at Clara E. Chan Lee Residences in Oakland's Chinatown, the 97-unit affordable senior housing project we're building alongside EBALDC, just steps from Lake Merritt BART.

The new law streamlines financing and cuts red tape for affordable housing across California, helping projects like this one move faster.

We're proud our job site got to be part of that moment, and even more proud of what's coming this fall: 97 new homes and a 14,000-square-foot public plaza built right on top of a BART tunnel.

Thank you to EBALDC for having us at the table. We can't wait to hand over the keys this fall 🏗️

One city. Five teams. Countless laughs. 😄

This year's Cahill Scavenger Hunt had us striking celebrity poses, reenacting iconic moments, dancing through history, battling brain freezes, and thinking outside the box to complete creative challenges across San Francisco.

The competition was fierce, the teamwork was unmatched, and the memories were even better. Congratulations to the Purple Banditos for earning the top spot! 🏆💜

And big thanks to everyone who participated! We're already looking forward to next year's adventure.
