Who We Are

ONEC Construction is a full-service general contractor. Our business success is driven by our ability to develop strong relationships with our clients by understanding their needs and requirements.

Through our management team, we have coordinated, scheduled, supervised and efficiently time-managed subcontractors, framing crews, and labor pools from excavation and underground utilities to completion.  We have also effectively brought closure to projects ahead of schedule. We have maintained a solid record of quality, reliability and customer service in a very demanding industry. Our past experiences grant us the diversity to manage projects under a variety of conditions.
