about
Rock Solid Reliable
We are a fifth generation family business passionately committed to our craft, fiercely loyal to our clients, and grateful for our community. We’re honored to have helped shape California’s infrastructure over the last century and we are determined to keep building for its future.
Real Builders
We are a self-performing builder — a rarity among large commercial contractors today. We don’t just add a layer of management to your project, we figure out the most efficient building solutions and implement them with our own skilled teams.
Services
General Contracting
We are here for one purpose: to build. We typically self-perform 800,000 craft hours annually, leveraging our field expertise and deep project experience to hand deliver real solutions to our clients.
Preconstruction
Our subject matter experts provide leadership to improve project outcomes. Our precon services are so valuable that we have never not been awarded a construction contract after providing preconstruction services.
Collaborative Delivery
70% of our work is Collaborative Delivery, such as design build. We enthusiastically endorse and recommend alternative delivery approaches that foster teamwork and save time and money.
Hands-on & Competitive
Overaa’s depth of experience enables us to serve diverse markets including commercial, industrial, education, municipal infrastructure, healthcare, life sciences and multi-unit housing. Performing a mix of project types and delivery methods keeps us sharp and on the cutting-edge.
Safe
