What Barrett Mahony Consulting Engineers does
Barrett Mahony Consulting Engineers Ltd is a privately held civil and structural engineering consultancy founded in 1994 in Dublin by Vincent Barrett and Brian Mahony. The firm delivers project-based professional services including civil engineering design (infrastructure reports, SuDS, flood risk and traffic assessments), structural engineering design across residential, commercial, educational, healthcare, conservation and infrastructure sectors, and planning support services. It is differentiated by a specialization in volumetric modular construction developed since 2005, having overseen structural engineering of more than 35 modular buildings and twice broken the world record for tallest modular building (Ten Degrees Croydon, 44 storeys in 2021; College Road Croydon, 49 storeys in 2023). The firm also develops bespoke engineering methods such as steel pre-loading deflection control that reduced steel tonnage by approximately 35% on 10 Trinity Square, and holds expertise in Passivhaus-certified and constrained-site construction.
The business operates as a professional services consultancy generating revenue through tender processes and direct project appointments with developers, Approved Housing Bodies, local authorities, government departments, and private sector clients. It runs a tri-national footprint with headquarters in Dublin (52/54 Sandwith St Lower), a London office (5th Floor, Mill House, 8 Mill Street) established around 2010-2013 to serve the UK market, and a Sofia office (22 Zlaten Rog Street) established in 2016 managing 10+ structural design engineers. Headcount sits in the 51-100 range, with no external institutional investment and no subsidiaries. The firm is led by Managing Director Ciarán Kennedy (joined 1996, former ACEI President), co-founders Vincent Barrett and Brian Mahony, and a bench of directors (Rouslan Taskov, Michael Hughes, Ciaran O'Rafferty, Shane Linehan, Owen Carroll, Stephen O'Connor, John Considine) covering Irish, UK and Bulgarian operations. Recognized customers include Tide Construction, Greystar, Marlet Property, Castlethorn, UCD, the Irish Department of Education, Clopen Capital and Bray Studios.
