At the present time, more than 90% of our commissions are for all engineering disciplines.

The O’Neill Group constantly strives to provide solutions and outcomes that exceed client expectations. In this highly competitive field where differentiation of consultants is often distinguished by fees alone, we aim not only to provide timely service but to use our depth of experience to design buildings that encompass what we believe to be the essential ingredients of a successful project, i.e.:

• Design efficiency
• Cost effectiveness
• Sustainability

Our firm has developed a clear understanding of the importance of integrating structure and services given our multi-disciplined practice.
