Executive Chairman

Peter Glodic

On January 2nd, 2005, Omnii started its journey in Melbourne, Australia. From humble beginnings, my fellow co-founder Marcello Arbaci and I set out to provide a unique service offering to the building and construction industry. That is, true consulting engineers, specialising in fire safety engineering and fire protection services design. Since that day, we have grown to be the largest specialist fire engineering and fire protection services consulting practice in Australia.

Peter is the Co-Founder and now Executive Chairman of Omnii Consulting Fire Engineers and has over 26 years’ experience in the Building and Construction, Fire Protection and Fire Safety industries.

As Executive Chairman, Peter has responsibility for Board Leadership, interfacing with the CEO, ensuring all parties are adhering to the mission statement, review of compliance issues, provision of guidance on market issues impacting the company, and to ensure ethical business practices are in place.

Peter has significant consulting engineering expertise. This includes an intimate technical knowledge of all facets of fire protection services and fire safety engineering and a myriad of project delivery methods and risk mitigation techniques.

Consequently, Peter has provided an advisory role to a number of Government Departments and has been engaged as an Expert Witness in varying jurisdictions across Australia.
