Opinion | Dr Paul Davis, Dublin City University
Ireland’s construction sector was not in good health before the Middle East escalation. It is in measurably worse health now.
The question is not whether the current geopolitical shock will affect housing delivery and infrastructure timelines. It already has. The question is whether anyone in a position to act is willing to say so plainly.
The numbers were moving in the wrong direction before the Strait of Hormuz closure disrupted commercial shipping in late February. The Central Statistics Office‘s wholesale price index showed construction materials and wages rising 2.3% year-on-year in January 2026.
Concrete blocks and bricks were up 8%. Chemicals and petrochemicals — the feedstock for insulation, membranes, PVC, and adhesives were up 21%.
The ESRI raised its inflation forecast for 2026 to 3.2%, the highest since the energy crisis of 2022–23, and warned explicitly that conflict-driven construction inflation could hamper the building of new homes.
None of this was a surprise to anyone working in the sector. It was, however, apparently a surprise to the policy conversation, which continues to discuss housing targets and infrastructure ambitions as though the cost environment were a background condition rather than the central constraint.
Construction Costs Go Up Easily and Come Back Down Slowly
There is a structural feature of construction costs that policymakers consistently fail to internalise. These costs go up easily and resist coming back down.
After 2008, when house prices collapsed by half, construction costs barely moved. Labour does not un-skill and re-skill freely. Supply chains do not reverse. Manufacturers hold prices once they have been repriced, because energy and input costs do not reverse either. What falls after a shock is activity, not price. You get fewer projects, not cheaper ones.
Between 2019 and 2023, construction costs rose by roughly 25%. Almost none of that was given back during the relative stabilisation of 2024–25. The Central Bank noted that Ireland was already at the higher end of the price spectrum in Europe for construction costs. The Society of Chartered Surveyors Ireland‘s Tender Price Index acknowledged that the moderate inflation of early 2025 was fragile, and that geopolitical uncertainty had the capacity to cause fresh supply chain disruption.
What the current shock does is move the ratchet again. The new floor becomes the baseline for the next disruption. And in a country that imports 79.6% of its energy and all of its oil, every energy-intensive build is structurally exposed.
The Hidden Cost of Timing
The timing of these cost increases is asymmetric, and this matters in ways that are not visible in headline figures.
Contracts already in delivery are locked into yesterday’s cost assumptions. Contractors facing fixed-price agreements will experience margin erosion. They will not collapse visibly — they will deliver defensively. In practical terms, that means a slower pace, disputed variations, and under-resourced sites. The project gets built, but worse, with fewer units, running late.
Contracts going to tender in the next three to nine months will be priced at today’s risk plus a forward volatility premium. There will be fewer bidders. The cheapest bid should be the most worrying. It means someone has priced the risk away and will claim it back on site over the next three years.
Projects still in design or planning face the starkest problem. Business case costings approved at 2024 prices are already stale. The €275 billion National Development Plan envelope may remain politically intact, but if the same envelope buys less concrete, less steel, and fewer contractors, real output falls while the ambition stays on the press release.
The National Children’s Hospital Is the Warning Sign Nobody Acted On
The National Children’s Hospital remains the most vivid illustration of what happens when a major public contract meets sustained inflation, design change, and contractual dysfunction simultaneously.
Originally costed at €650 million, it is now approaching €2.24 billion. A further €853 million in BAM claims remains undecided. There are 3,277 outstanding contractor claims and an 18th missed deadline. The hospital was supposed to open in 2020. The committee chair now suggests autumn 2027.
MetroLink is entering the procurement market at the worst possible moment. The retrofit programme, intended to insulate Ireland’s homes against energy shocks, depends on materials whose prices rise every time there is an energy shock. That is not a design flaw in the programme, but it is a real tension that nobody in government is addressing.
Three Things That Need to Change
The discipline of procurement cannot reprice global energy markets or reroute shipping lanes. But it can do several things that are not currently being done.
First, every major public contract should be designed from day one as though a geopolitical or energy shock is possible. In a seven-year infrastructure programme, there will statistically be a shock of some kind. That means price variation clauses, shorter fixed-price periods, review triggers linked to materials indices, and supplier financial monitoring so that contracting authorities know when a contractor is in trouble before the contractor stops showing up on site.
Second, the government needs to be honest about prioritisation. The ESRI has said plainly that the economy cannot deliver so many infrastructure needs in a limited timeframe. That is polite language for: you cannot do everything at once at these costs. Pretending otherwise does not produce more houses. It produces more cost overruns.
Third, the National Development Plan needs a public, transparent mechanism for updating cost assumptions in real time. The current practice in which estimates are set at approval and not revisited until a crisis forces reappraisal is how you get a children’s hospital that costs five times its original estimate and a metro system that has not yet broken ground.
M10News has been reporting on how construction costs and the Iran crisis are feeding further pressure into Ireland’s already strained housing delivery pipeline and on the government’s 300,000-home target and the gap between what is being promised and what the cost environment makes deliverable.
Ireland was already building too slowly and too expensively. The current shock does not create a new crisis. It makes the existing one significantly harder to solve. The least useful response is to pretend otherwise.
