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

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.
Agile & 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.
