Consulting Engineers/Quantity Surveyors

About Us

Since 1991, ORS has led the way in anticipating and responding to the diverse client requirements in the Irish construction industry. Time and experience have enabled us to create significant additional value in our projects with the blending of nine distinct, specialist design and build services. This multidiscipline approach uniquely includes civil and structural engineering, project management, infrastructure, health and safety, building surveying, assigned certifier, fire safety, energy management, and environmental services.

Over the decades, we have developed trusted, lasting partnerships with our property developer, international project funding agency, local authority, government agency and private clients. Our end-to-end project collaboration with stakeholders, architects, design teams and contractors ensures excellent, innovative solutions.

Our success is made possible by our invaluable, industry-leading team of designers, consulting engineers, planners, scientists and surveyors. Sustainability is proudly at the heart of every ORS project.

ORS is growing, following significant investment from Erisbeg in late 2022. This investment enables us to continue to grow and maintain our award-winning culture while meeting the growing needs of our expanding client base nationwide.
