About us

About mcor

Mcor is a progressive and forward-thinking quantity surveying firm that came into being when MMC and Tony O’Regan Associates joined forces. This partnership combines MMC’s modern, innovative approach with Tony O’Regan’s extensive industry expertise and network. 

Together, we offer a unique blend of fresh thinking and decades of experience, creating a strong foundation for a new force in the quantity surveying industry.

Our work is driven by three core principles: Control, Value, and Sustainability.

We deliver precise control over costs, ensuring every project is financially efficient from start to finish.  But value for us is about more than just saving money – we tailor our solutions to maximise our clients’ return on investment.  And sustainability is central to our approach – through our specialised Life Cycle Assessment service where we can measure and manage the embodied carbon of buildings to Life Cycle Costing where we can optimise the life time cost of an asset, we are leading the way toward a more eco-conscious future in the sector. With a shared ambition and clear vision, we aim to become a leading name in quantity surveying, pushing boundaries through innovation and expertise. 

Ultimately, we believe in shaping a better, more sustainable world – one project at a time.
