What we do

Roughan & O'Donovan delivers high quality, safe and sustainable engineering design solutions for infrastructural projects.

Our team is experienced in setting standards, providing expert advice and delivering the design of a wide range of roads, rail, buildings, flood management, cycling and bus priority projects.

  • It has been an absolute delight to arrive on-site at Dublin Port and see magical elements, such as giant-like turnstyles, sculpted crane enclosure, floating bridge and ocean liner scaled sliding gates.
