New Principal

David Spriggs, PE

Division Manager

Structural Division

Hired at DAA in 2004

Dave has a broad background of experience in analysis and design of structural systems for industrial, commercial, and institutional buildings.  Much of his work has involved the alteration or addition to an existing building or facility, and consequently he is well versed in the complexities of integrating new structural elements into existing architectural and mechanical features.

Most Influential Project: One of Dave’s favorite projects was the Richmond International Airport Terminal Expansion. The terminal expansion project, completed in 2007 at a cost of approximately 47 million dollars, was a significant addition and renovation to the earlier terminal facility that dated back to 1927.

First Job: Now a part of key senior leadership, Dave hasn’t always been at the top. He started his career in food service at Jones Beach, NY.

(Both national and local architects were a part of the team – four architectural firms, in fact.)

Brent is an Engineer on the Blacksburg Site Development and Infrastructure team.  He is proficient in AutoCAD, AutoCAD Civil 3D, Revit, and many other computer drafting programs.

Michael also noted, “We had two crews form this office and up to three crews from Richmond working five days a week just on this job. So juggling five crews and the data that was brought in from the field was exciting.”

Lutheria Smith, SHRM-SCP, SPHR

Director of Human Resources

Human Resources

Hired at DAA in 2015

As the Director of HR at DAA, Lutheria says, “We don’t sell a product.

Thus, HR’s most important focus is attracting and retaining top talent to ensure that DAA continues to make a lasting positive impact.

First Job: Another job that taught Lutheria a lot was her first job as a babysitter to raise money for her 8th grade trip to Mexico. “I had to raise half of the fee for the trip and my parents agreed to match that amount,” say Lutheria. “In the end, they paid the entire fee for the trip because they were so proud that I worked to raise half the money.  That taught me a lesson that served as the foundation for a strong work ethic.”
