A property line is just a line… until it matters.

Surveying is one of those services that can seem simple from the outside—but accurate information at the beginning of a project can make a significant difference down the road.

Whether it’s a boundary survey, ALTA survey, construction stakeout, location survey, or as-built survey, the details matter.

At COA Barrett, our surveying team works alongside our engineering and land planning professionals to help give projects the accurate information they need to move forward.

Measure twice. Build with confidence.

🎀👻 Rain or shine, we show up for a good cause!

The COA Barrett team braved a cold, windy, and rainy morning at the CalvertHealth 5K Run/Walk in support of Breast Cancer Awareness Month! 💗 Our Halloween-inspired theme, “Breast Cancer Is Boo Sheet,” brought a little spooky fun to an important cause.

We loved seeing everyone embrace the theme, and our festive koozies were a hit! Missed out on grabbing one? We’ll have more available this Saturday at the Tractor Treat event at Mrs. Moo’s!

Thank you to everyone who came out to support breast cancer awareness and make a difference, no matter the weather.

What you see is the finished project. What you don’t see is everything that had to happen to get there.

Before the pavement, buildings, homes, and businesses come together, there are plans to develop, regulations to navigate, infrastructure to coordinate, and countless details to work through.

That’s where COA Barrett comes in.

From land planning and civil engineering to surveying and environmental services, our team helps move projects from an idea on paper to something that can actually take shape in the real world.

Because good development doesn’t just happen.

It’s planned. Engineered. Coordinated. Built.

Construction is moving forward at Armory Towns. 🏗️

As these townhouses take shape, COA Barrett is on the ground providing construction stakeout services to help ensure the project is being built according to plan and design.

From the plans to the field, accurate layout is an important part of keeping a project moving in the right direction.

Another step forward for Armory Towns and another project we're proud to support.

A new chapter is underway at Chesapeake Beach Waterpark. 🏗️

Demolition is currently underway as the Chesapeake Beach Waterpark project moves into its next phase. COA Barrett is proud to assist the Town of Chesapeake Beach and Schiebel Construction with the work happening behind the scenes.

Our team provided assistance with the MDE Notice of Intent (NOI), Stormwater Pollution Prevention Plan (SWPPP), and permitting to help support the project as construction gets underway.

Projects like this involve a lot more than what you see happening on-site. From permitting and environmental compliance to construction, each piece plays an important role in moving a project forward.

We're excited to watch this one progress and see what's next for this Chesapeake Beach landmark. 👀

We had a great time connecting with students at USMSM's Open House! From exploring future careers to learning more about internships and apprenticeships, it was great to see students thinking about what’s next.

We were especially excited to have Makenzie, our current high school apprentice from North Point High, join us and share a real-life look at what an apprenticeship can look like in practice. We’re always excited to connect with the next generation of talent and help students see what opportunities are out there!

Behind every construction project is a lot more than what you see in the final product.

At Armory Pavilion, COA Barrett is assisting with construction administration and Requests for Information (RFIs) to help keep communication, documentation and project decisions moving throughout construction.

While the work happening in the field gets the attention, the coordination happening behind the scenes is just as important.

One project. Plenty of moving pieces. We're helping keep them connected.
