Our Approach

The O|N|E Approach

we developed an approach that focuses on the outcomes, needs and expectations of the owner and project team. We call it the o|n|e approach. Starting with the outcomes establishes the context of the project and gives direction. Understanding the needs of the owner, design and construction team, we’ll have better opportunities for innovation. Finally, defining the expectations early-on provides us, and the entire team, performance indicators so there are fewer costly surprises.
