AECOM Ireland
AECOM's Irish practice, whose published materials cite a 165-year legacy in Ireland, with cost management and quantity surveying among core services.
Ireland's construction-consultancy market pairs Irish-founded practices — some now global — with the international majors. This guide from COVA names the seven firms an asset owner should genuinely consider.
This guide is published by COVA Group and includes COVA. Every statement about another firm comes from that firm's own published materials, reviewed in August 2026, and firms are listed alphabetically.
How firms were selected
Firms are included when they hold an established Irish office, offer project management or quantity surveying as core consultancy services to asset owners, and have a publicly verifiable Irish track record.
