BIM Mandates & Public Projects in Ireland 2025

The Irish BIM mandate landscape in 2025 is more complex than a single sentence can capture. There is no single national mandate that applies universally to all Irish building projects — instead, there is a framework of sector-specific requirements, procurement thresholds and state agency standards that together create a BIM-mandated environment for the majority of significant Irish public capital projects. For Irish MEP consultants, architects and ELV designers seeking to work on the €165 billion NDP pipeline, understanding which Irish bodies mandate BIM, at what threshold and under what standard is operationally critical — not academic.

The Irish Public BIM Mandate Landscape — 2025

The Irish BIM mandate operates through multiple overlapping frameworks rather than a single national act. The primary vehicles are: the OGP Public Works Contract suite (which incorporates the OGP BIM Framework); state agency-specific EIR standards (HSE Capital Programme, DoE, TII); and the National BIM Council Ireland's roadmap, which sets the strategic direction for mandate expansion. Understanding which framework applies to a specific commission — and what it requires in terms of BEP, LOD and CDE — is the starting point for BIM compliance planning on Irish NDP projects.

National BIM Council Ireland — Roadmap and Progress

The National BIM Council (NBC) Ireland, operating under the Department of Public Expenditure and Reform, publishes a BIM adoption roadmap for the Irish construction sector. The roadmap targets mandatory ISO 19650 BIM on all public capital projects above defined threshold values by 2026, with progressive extension to all publicly funded works through 2030. The NBC also provides: EIR template guidance for state agencies; BEP template guidance for design teams; CDE platform evaluation criteria; and CPD guidance for Irish practitioners.

The OGP BIM Framework — What It Requires

The Office of Government Procurement (OGP) BIM Framework is embedded in the Public Works Contract suite — the standard procurement framework for all Irish government capital projects. The framework mandates ISO 19650-aligned BIM on contracts above the threshold value and introduces standardised EIR, BEP and MIDP requirements across all state agency commissions.

OGP BIM Threshold Values and Scope

The OGP BIM Framework currently mandates BIM on public works contracts above approximately €10 million construction value. Below this threshold, BIM is not mandatory on OGP contracts — though state agencies may apply BIM requirements at lower thresholds through their own EIRs. The threshold is under review for reduction as part of the NBC roadmap.

Pre-Contract BEP Requirements

On OGP-mandated projects, the design team must submit a pre-contract BEP with its tender response — confirming BIM capability, proposed CDE platform, software versions, LOD progression and MIDP framework. A weak or generic pre-contract BEP is a tender evaluation risk; OGP evaluators assess BIM capability as part of the quality criteria in the MEAT (Most Economically Advantageous Tender) assessment.

HSE Capital Programme BIM Requirements

HSE BIM Threshold, CDE and LOD Requirements

The HSE Capital Programme applies BIM requirements to all major capital projects above approximately €5 million total project cost. HSE BIM requirements are more prescriptive than OGP — specifying: the CDE platform (typically ACC or Asite); the BEP template structure; the LOD at each RIAI stage gate; ELV and ICT discipline model requirements from Stage 2; asset data (LOIN) requirements for FM handover; and MIDP delivery dates aligned to the HSE's capital programme stage gate schedule. HSE project-specific EIRs are issued at procurement stage and override OGP generic EIR templates where they differ.

Department of Education School Building Programme

The Department of Education (DoE) requires ISO 19650 BIM on all new-build schools and major extensions — effectively applying BIM to all significant school building projects regardless of value. DoE BIM standards specify: federated model coordination from RIAI Stage 2; ELV systems (fire alarm, structured cabling, AV, security) modelled in Revit from Stage 3; clash detection between ELV containment, structural and MEP services before Stage 4 issue; and IFC export of the coordinated model for digital handover to the school's building management team.

Transport Infrastructure Ireland (TII) BIM Standards

TII applies BIM on all major road and transport schemes — using the TII BIM Delivery Standard, which aligns with ISO 19650 but adds infrastructure-specific requirements for linear project data management. For ELV designers on TII commissions (roadside ELV systems — CCTV, VMS, access control for maintenance buildings), the TII standard applies alongside ISO 19650 for the building infrastructure elements.

Preparing Your Irish Practice for the Full NDP BIM Pipeline

Upskilling vs Outsourcing — The Strategic Choice

Irish practices facing NDP BIM requirements have two strategic routes: build in-house ISO 19650 capability through recruitment and training (6–18 months minimum), or establish outsourcing arrangements with specialist remote BIM teams immediately. Most established Irish practices use a hybrid model — retaining design authorship and client communication in-house while outsourcing Revit modelling, coordination and clash detection to remote specialists.

ASDV provides BIM support services for Ireland specifically structured around the ISO 19650 requirements of Irish NDP commissions. See our ISO 19650 explained guide and our NDP BIM requirements detailed guide for the full context.
