Our team recently attended Procore’s Groundbreak conference, joining builders, owners, and technology leaders from across the construction industry.

Technology plays a big role in how we plan, manage, and deliver our projects, and Groundbreak is a great opportunity to stay at the forefront of the tools our teams use every day.

Project Spotlight: NVCC CF Building in Annandale

At the heart of Northern Virginia Community College’s Annandale Campus, the CF Building is where students come to eat, study, and connect between classes. As its systems aged and student needs evolved, the college set out to reimagine the building for the next generation of NOVA students.

The renovation centered on the spaces students use every day. A new café and multipurpose lounge anchor the second floor, and the food service areas and student activity spaces were completely transformed. Behind the scenes, our team also upgraded the building’s mechanical systems, installed a new sprinkler system, enhanced the lightning protection, and updated the exterior.

Today, the nearly 30,000 SF building is better designed to bring students together.

Thank you to Northern Virginia Community College and Cole & Denny Architects for partnering with us on this project, and a big thank you to our project team, Chip Thomas, Clark Thomas, Ian Loch, and Zikiyaa Moody, and to our trade partners for their hard work!

Construction has begun at Seaton Elementary School!

Built in 1969 in DC’s Shaw Historic District, Seaton is getting a major modernization. Together with CGS Architects and the DC Department of General Services, our design-build team is renovating and expanding the school to about 91,000 SF, bringing it up to today’s educational standards.

We’re proud to help deliver modern, welcoming learning spaces for Seaton’s students, and we look forward to sharing updates as the school takes shape.

Earlier this month, our team joined more than 500 industry leaders, elected officials, and community champions at the Metro DC Hispanic Contractors Association’s 2026 Annual Gala at the Smithsonian American Art Museum.

This year’s theme, “Building the Future Together,” marked more than four decades of the association’s work supporting small, minority, and Hispanic contractors across the DMV.

Many of the firms in the room were trade partners we build alongside every day, on commercial interiors, base building and multifamily, and historic modernizations across the region. It was a great night to celebrate that work together.

Congratulations to this year’s honorees and thank you to the Metro DC Hispanic Contractors Association for a memorable evening!

We gathered on site at Barcroft Apartments in Arlington to celebrate the end of the project with the trade partners and team members who helped us get here.

A big thank you to our project team, John Dave Tinawin, Kevin Reid, Morgan Parker, Clark Thomas, Ingrid Suarez, Kendrick Tillman, Adam Turner, and Alessandro Canale. And thank you to every one of our trade partners on Barcroft, including LMS Mid-Atlantic, Mackey Electrical Services, Tricord Masonry, Delta Paint, King Carpentry, Potomac Waterproofing, National Cable, Complete Landscaping Services, Alcoa Concrete, SCW Mechanical and Plumbing, and more.

We’re proud of what we built together, and we look forward to many more projects with these teams.

16 women from across GCS-SIGAL, from project management and preconstruction, to marketing and financial services, spent the day at the 2026 Women in Construction Conference.

Sessions covered how AI and new technology are changing our work, communication skills we can put to use with our teams and our clients, and how to attract and keep the next generation of construction talent.

Between sessions, our team connected with women leading projects, firms, and agencies across the region. We're proud to support the women who help build the DMV every day, and grateful for the chance to learn alongside them.

What happens when architects and builders are part of the same team from day one?

GCS-SIGAL's Gabe Oliver and CGS Architects' Derek Banocy recently joined Virginia Tech Architecture and Construction Management students for a guest lecture on the Duke Ellington School of the Arts project and the power of design-build from procurement through project delivery.

We’re always excited to share what we’ve learned in the field with the next generation of architects, builders, and industry leaders.

What does it take to bring a 115-year-old school back to life?

We recently welcomed members of APT DC (the DC chapter of the Association for Preservation Technology) to our Crummell Community Center project in Ivy City for a site tour led by EHT Traceries.

Originally completed in 1911, the Alexander Crummell School sat vacant for years and was named one of the DC Preservation League's Most Endangered Places. Today it is being transformed into a community center for the Ivy City neighborhood.

We’re proud to be part of a project that brings new life to the Crummell building while honoring an important piece of the District's history.

Thank you to APT DC, EHT Traceries, Genco Masonry and DLR Group for helping make this site tour possible.
