Ray Mason Gillian Corrigan Cian Dowling
Director Director Director
A Director and company Principal at Axiseng, Ray was a founding staff member of Axiseng when it was established in 2004 and he has played a pivotal role in the firm’s growth and development since then. Over two decades as a practitioner, Ray has honed his engineering and project management skills to become a respected industry figure and a ‘go-to’ resource for commercial, industrial and business critical infrastructure projects.
With a keen interest in institutional, new commercial and commercial fit-out projects Ray has overseen the delivery of complex M&E projects ranging from healthcare buildings and schools to new commercial and office fit-outs. A born collaborator Ray is highly skilled at getting the best out of multidisciplinary teams in the delivery of fast-track fit-out projects for domestic and multinational clients. Prior to joining Axiseng, Ray worked with two respected independent consulting engineering practices in Dublin.
A chartered accountant by profession, Gillian is Financial Controller and a Director of Axiseng which she joined more than a decade ago. Gillian’s financial rigour and discipline reflects a firm-wide professionalism that is client-centred and results focused regardless of the scale or pace of a project. Gillian’s attention to detail, ‘can do’ attitude and strict adherence to client, statutory and regulatory requirements means she plays a central role in project resourcing, tracking, reporting and accountability. Gillian began her career in information technology working as a project manager in e-learning and web development before moving into accountancy. As a result, she is well accustomed to delivering technically demanding and precise service in time critical environments. Prior to joining Axiseng, Gillian worked in private practice. A Director and company Principal at Axiseng, Cian has worked in the Building Services industry and advisory space for over two decades.
Over the past number of years he has been project lead on a range of prestigious commercial, industrial and business critical infrastructure projects, with clients such as Kennedy Wilson, Facebook, Google and JP Morgan. Over recent years Cian has specialised in the delivery of fast-track fit-out projects in excess of 1m sq. feet for discerning, time-critical projects for multinational clients. His high-quality engineering solutions typically include energy-aware design solutions tailored to a client’s specific requirements and preferences.
