What ORS does

ORS is an Irish multidisciplinary building consultancy founded in 1991 and headquartered in Mullingar, Ireland. The firm provides advisory, design, fire safety, environmental, and mechanical and electrical engineering services to clients across the construction lifecycle, addressing tightening Irish building regulations through integrated specialist expertise. The service portfolio combines organic capabilities with acquired brands, including ProFire & Design (fire safety, acquired August 2024), O'Callaghan Moran (environmental consultancy, acquired April 2025), and Coffey Consulting Engineering (M&E services, acquired April 2025).

The business operates as a B22 professional services platform generating revenue through project-based consulting engagements priced quote-by-quote. Distribution is via direct enterprise field sales to construction-sector clients — primarily commercial property developers, contractors, and businesses requiring regulatory compliance support — with no public pricing or productized offerings. Headcount of 251-500 employees and €25M in revenue (a 300% increase since 2022) reflect an active roll-up strategy executed under private equity ownership.

The company is privately held and has been majority-owned by Erisbeg since January 2023, which initiated the acquisition-led expansion. In June 2026, Goldenpeak acquired a majority stake (with Alantra advising) to fund the next growth phase, explicitly including acquisitions and geographic expansion into the UK and internationally. No AI or proprietary technology capabilities are disclosed in the available data, and the firm's competitive position rests on regulatory expertise, multidisciplinary talent, and acquired specialist brands rather than software or data assets.

Direct peers

• Punch Consulting Engineers: Irish multidisciplinary engineering consultancy offering civil, structural, mechanical, electrical, and environmental engineering services. Highly comparable to ORS's combined advisory, design, fire safety, and M&E platform serving the Irish construction sector.
• RPS Group: Ireland-origin consulting firm providing engineering, environmental, and project management services across the construction lifecycle. Directly comparable to ORS in service mix and Irish heritage, now operating under Tetra Tech.
• Waterman Group: UK-based building consultancy providing structural, civil, M&E, and environmental engineering services. Closely comparable business model and service mix to ORS, particularly relevant given ORS's UK expansion ambitions.

Broad incumbents

• Arcadis: Global design and consultancy firm operating in Ireland across buildings, environment, and mobility. Comparable multidisciplinary consulting profile but as a broad incumbent versus ORS's focused domestic platform.

• WSP: Global professional services firm with significant Irish presence offering engineering, environmental, and advisory services. Comparable in multidisciplinary service scope but at vastly greater scale and geographic reach.
• Sweco: European engineering, design, and environmental consultancy with established Irish operations. Comparable multidisciplinary service portfolio at much larger scale, representing a scaled incumbent ORS competes against.
• Mott MacDonald: Global engineering, management, and development consultancy with significant Irish operations. Comparable in providing multidisciplinary advisory and design across the construction lifecycle, but at materially greater scale.
