We’re true partners on every job. In many instances, OSC is engaged as early as our clients need and throughout the entire process.

Our Services

At OSC, we’re more than a construction firm. We’re true partners from the moment the bidding process begins. By providing a detailed review of documentation, we highlight gaps in a project’s scope and ensure all parties are aligned on goals from pre- to post-construction.

After bidding, we draft a plan customized to your goals, specifications, budget and timeline. Every step of the way, this plan is executed with safety at the forefront. We pair our safety mindset with a level of “white glove” service that exceeds expectations, every time. Taken together, this approach maximizes every dollar spent without comprising safety or quality.

We pair our safety mindset with a level of “white glove” service that exceeds expectations, every time.
