In 1974, Derry Roughan and Joe O’Donovan form Roughan & O’Donovan Consulting Engineers (ROD). 

The firm opens its first office at The Hill, Stillorgan, Co. Dublin. 

The first employee is Des Kernan, senior technician. Early projects included schools, golf clubs, supermarkets, industrial developments for IDA Ireland and the design of the Knocknadangan and Uggool bridges in Co. Mayo.

 Staff numbers grow to 15 by the end of the decade.


With the prolonged recession limiting work in Ireland, the company pursues international projects, particularly in Saudi Arabia.

Two new partners, Garry Smyth and Shay Ryan, and two leading academics, Dr. Eugene O'Brien and Dr. Pat Maher, join the team to support the company's growth and development.

Key projects include six bridges on the M50 ring motorway in Dublin and four bridges on the N3 Blanchardstown bypass and Clonee bypass.


Economic recovery in Ireland allows ROD to grow its reputation for technical expertise and skill in the design of bridges, buildings and transportation.

Bridge projects include the William Dargan Bridge and Mary McAleese Boyne Valley Bridge.

Road projects include Citywest junction on the M7, M1 Drogheda bypass and M1 Dundalk Western bypass PPP (JV with MCOS).

Buildings projects include civic buildings, court houses, restorations at Newman House and Castlemartin House, social housing developments and apartment complexes across Dublin.

ROD acts as the Irish partner and independent checker for the bridges designed by Santiago Calatrava in Dublin, namely, the James Joyce Bridge and Samuel Beckett Bridge.

The company is part of the international team who successfully deliver Ireland's first ever light rail project and also undertakes a 10-year level crossing replacement project for Irish Rail.

ROD undertakes a commission to adapt the UK standards for Ireland and update both the National Roads Authority’s ‘Design Manual for Roads and Bridges’ (DMRB) and the ‘Manual of Contract Documents for Road Works’ (MCDRW).

ROD is heavily involved in the Irish motorway programme, undertaking the design of motorway with a construction value of €2.36b.
