Our Story

Two brothers…forward-thinking innovators and entrepreneurs…together, started a small carpentry business in 1873 that flourished through a hard-earned reputation for quality and dedication to excellence. That same spirit has stayed true over generations of Gilbane family members. From our earliest roots, we’re builders. Talk to us today, and you’ll experience not only those core values but also a company that’s continuously evolving and changing the building industry status quo.

We are a global integrated construction and facility management services firm. Our clients entrust us to deliver the projects that will build their futures. From sustainable building to the latest in Lean construction technology and management, above all else, we are advocates for our clients. We’ll make your goals our own, and strive relentlessly to exceed them.

Still a privately held, family-owned company, we know a thing or two about loyalty, stability, and trust. At the heart of our success is our team of employees across the world whose passion, commitment, experience, and integrity are a central part of every project we deliver.
