This Memorial Day, we honor the men and women who served and sacrificed for our country. Their courage and commitment laid the foundation for the freedoms we rely on every day.

As architects, we are driven to design spaces that endure, shaped by purpose and vision. The work we do is made possible by the sacrifices of those who protected this nation, and we remember their legacy with gratitude.

Wishing you a safe and meaningful holiday.

We’re kicking off our summer intern season and can’t wait for you to meet some new faces! Please join us in welcoming Sam Puent to the RCDG team.

Sam is a student at the University of Missouri studying Architectural Studies with minors in Construction Management and Sustainability. She’s passionate about design, especially after being inspired by her family’s home rebuilding following the Washington Strong tornado.

This summer, Sam is excited to grow her skills in design, software, and collaboration while learning from the team. She’s all about staying curious, open to feedback, and building strong connections.
Fun facts: she’s a proud cat mom, would happily eat a burrito every day, and can do a mean worm on the dance floor

Her motto? “If it doesn’t challenge you, it doesn’t change you.”

Welcome to the team, Sam!

Construction Safety Week reminds us that safety starts long before the first shovel is in the ground. As architects, we share responsibility for protecting those who bring our designs to life…every day, on every project.

This year, the focus is on three simple but powerful actions: Recognize the risks, Respond with intention, and Respect the people around you. By designing with safety in mind, especially for high-energy, high-hazard conditions, we can help prevent serious injuries and save lives.

We’re ‘All In Together’. Let’s continue to design thoughtfully, collaborate closely, and do our part to ensure everyone goes home safely.

The Central Illinois team had the opportunity to learn cricket from our own Jay Narayanan! In his spare time, Jay enjoys playing cricket and was kind enough to share his passion with the team.

Jay began his career as an Assistant Project Manager for a company in London and joined River City Construction’s Operations Team last August.

Thank you, Jay! We had a great time together, learning something new, and bonding with coworkers.
