B3 General Construction (B3GC) was founded as Bill Beckwith Builders in 2006 in Naperville, Illinois. The company expanded into commercial construction in 2009, becoming licensed general contractors.

Today B3 General Construction handles commercial projects nationwide. They are the preferred contractor for FIVE GUYS BURGERS & FRIES and have successfully built nearly 75 locations across the country. Besides their central location in Naperville, they have an office in Naples, Fla.


Our practical knowledge of scheduling and budgets, commitment to planning details, diligent project oversight and access to dependable resources has led to our reputation for superior project outcomes, often finishing projects within budget and as much as 30% ahead of schedule. In many cases, our successful completion of what were one-time projects has motivated clients to seek out longer-term working relationships with B3.

From full fit-outs for restaurants and custom retail spaces to municipal building and renovation for educational and government facilities, B3 has the experience and knowledge to deliver superior results and quality service to the clients we serve.
