B.I.G. Is Now LINX
Building Infrastructure Group — B.I.G. — is now part of LINX. The team, the office in Chantilly and the work continue as they were; what changes is the depth of resource behind them.
Based in Chantilly, we serve clients across Northern Virginia, Washington, DC, and surrounding markets in Maryland and Virginia. Our work spans structured cabling, wireless and distributed antenna systems (DAS), audiovisual solutions, security, and secure facility infrastructure.

Where We Work
Our Northern Virginia team works across the Washington metropolitan area and into the surrounding Virginia and Maryland markets. Frequently served locations include:
Northern Virginia
Chantilly, Reston, Herndon, Dulles, Arlington, Alexandria, Tysons, Fairfax and Loudoun County.
Washington, DC
Downtown, Capitol Hill, NoMa, the Navy Yard and the wider District.
Maryland
Baltimore, Columbia, Bethesda, Silver Spring and the Baltimore–Washington corridor.
Greater Virginia
Richmond and the I-95 corridor, with project work statewide.
If your project sits outside these areas, it is still worth asking — LINX operates nationally from offices in Colorado, Utah, Wyoming and the Pacific Northwest, and larger programs are routinely delivered across multiple markets.
What We Deliver From Chantilly
- Structured cabling — copper and fiber backbone, horizontal distribution, testing and certification.
- Wireless and DAS — in-building cellular and distributed antenna systems, and emergency responder radio coverage.
- Audio visual — conference rooms, boardrooms, training spaces and digital signage.
- Security systems — access control, video surveillance and intrusion detection.
- Data center infrastructure — cabinet and containment build-out, structured cabling and cross-connect.
- Secure facilities — infrastructure for classified and controlled environments.
Most projects in this region involve more than one of these, which is the main reason they are worth holding under a single contractor rather than coordinating separately.
The Buildings We Work In
The Washington region has a particular mix of building types, and the technical requirements differ sharply between them.
- Government and defense — including secure and classified environments with their own separation and accreditation requirements.
- Commercial office — base building infrastructure and tenant fit-out, from single floors to full repositioning.
- Data centers — a defining sector of this corridor, with its own density and containment standards.
- Healthcare and education — occupied environments where sequencing matters as much as the installation.
- Multifamily and mixed use — in-building wireless and resident connectivity, plus code-required public safety coverage.
