Where over a century of experience meets a commitment to innovation and to each other.
We are defined by deep and extensive expertise, creative thinking and a people-first culture. Established in 1919, Weeks draws on over a century of successes to create the most effective and innovative solutions in marine construction, dredging, marine services, tunneling and aggregates, combined with the best-in-class equipment. Our family environment makes us special, motivates us to come to work every day – and ensures our work excels. At the start of 2023, the Weeks organization was acquired by Kiewit Corporation to become wholly-owned subsidiaries of Kiewit.
Thanks to our five specialized areas of expertise, including three far-reaching subsidiaries, we are a one-stop shop for turnkey solutions around the world. The work we do with our governmental clients often serves entire communities and the projects completed for private clients provide vital services that sustain the global economy and our way of life. Therefore, it is with pride that we take on each project, while we continue to invest in our team of leaders, experts and crews.
