Who We Are

We are an innovative general contractor serving the San Francisco Bay Area.

We have a passion for construction and the drive to build superior structures at a fair price. At Alten Construction, our clients come first. We listen. We hear your challenges and goals, and put our experienced team of experts to work to deliver a finished structure that will exceed your expectations and be a centerpiece of our community for generations to come.

We aren’t just a general contractor. We’re also a builder able to complete many of the critical elements of the project ourselves, such as demolition, concrete, masonry, rough and finish carpentry. We know how to budget our time and our resources to deliver a quality structure on time and on budget.

We don’t stand still. As a company, we strive to always get better, to improve our processes and raise the bar for ourselves and for the building community. As leaders in the San Francisco Bay Area building community, the team at Alten Construction continually looks for ways to improve our safety, our sustainability, and the building experience.

Innovation at its best

Using technology to improve the way we do business.

Living and working so near Silicon Valley has given us a unique perspective on how technology can shape the way we do business. By pairing the best hardware and software for the construction industry, we have improved the flow of information both on the jobsite and to our clients. Because our project managers and superintendents can instantly access the project schedule and drawings while in the field, we can ensure that we stay on budget and on schedule at every stage in the build process.
