We Are the Engineering Partner Your Project Deserves
Hayes Mechanical & Engineering is a specialist mechanical and structural engineering contractor serving main contractors, developers, data centre operators, pharmaceutical manufacturers, and project teams across Ireland, the UK, and Europe. We combine deep technical expertise with a direct, client-focused approach – giving every project a skilled team, clear documentation, and dependable delivery from brief to handover.
Our two core services cover the full scope of mechanical and structural engineering: from high-purity stainless steel process pipework and HVAC building services, CHW and LPHW systems, BMS, and package plant rooms – through to structural steel fabrication and installation. Both services are delivered from our purpose-built workshops in Co. Mayo – a 16,000 sq ft carbon steel facility and a fully segregated 7,000 sq ft stainless steel workshop.
Whether you are delivering a data centre, a pharmaceutical facility, a commercial development, or a healthcare project, we bring the engineering rigour, fabrication capability, and on-site experience your project demands.
Our mission is to deliver mechanical and structural engineering solutions that are precise, fully compliant, and built around our clients’ goals. We believe exceptional engineering means clear communication, thorough documentation, and results that stand up to scrutiny — on every project, for every client, without exception.
Our vision is to be the most trusted mechanical and structural engineering consultancy for clients across Ireland and Europe — recognised for our technical precision, responsive service, and ability to deliver complex engineering to the highest international standards.
We try to the best of our capacity!
