Quantity Surveyor Jobs

With 73 active roles across Ireland's booming construction sector, quantity surveying remains one of the most in-demand professional disciplines in the built environment. Dublin accounts for 48 positions, with Cork (7), Kildare (4), and Limerick (3) reflecting regional infrastructure investment.

The employer list reads like a who's who of Tier 1 Irish construction. Mercury Engineering leads with 10 positions across its mechanical and electrical contracting operations — Ireland's largest M&E contractor, working on data centres, pharmaceutical facilities, and commercial buildings. Turner & Townsend has 8 QS roles in its cost consultancy practice. BAM recruits 7 quantity surveyors for road, rail, and civils projects. Cairn Homes has 7 positions for its residential development programme. AECOM at Burlington Plaza recruits 6 cost management professionals.

The specialist contractors add depth. Winthrop Technologies has 6 QS positions for data centre MEP projects — a high-value niche where cost accuracy directly impacts project viability. Ardmac recruits 5 quantity surveyors for its fit-out and cleanroom construction business. HMV Engineering adds further electrical contracting QS demand from Limerick. John Sisk & Son recruits through its main contracting and Sensori facilities management divisions.

What does a quantity surveyor actually do? The role covers cost estimation, bill of quantities preparation, contract administration, interim valuations, and final account negotiation. In practice, you're the financial conscience of a construction project — ensuring that costs are controlled, variations are properly documented, and the client or contractor gets value for money. For consultancy firms like Turner & Townsend and AECOM, the role is client-facing, providing independent cost advice. For contractors like Mercury and BAM, it's commercially focused, managing procurement, subcontract packages, and margin protection.

Qualifications typically require a Level 8 degree in quantity surveying or construction economics, with SCSI (Society of Chartered Surveyors Ireland) or RICS membership as the professional standard. Key skills include measurement, NEC and GCCC contract knowledge, cost planning, and increasingly BIM 5D cost modelling. The career ladder runs from Graduate QS through Intermediate QS and Senior QS to Commercial Manager and Commercial Director — a path that leads directly to the boardroom of major construction firms.
