New Children's Hospital, St James's Campus, Dublin

The building is finished enough to look finished. That is the problem with writing about it. Seven storeys above ground, 160,000 square metres, 6,150 rooms, sitting on the St James’s campus in Dublin 8, and as of August 2026 nobody can say when it will take a patient.

Project Scope

380 single inpatient rooms, every one en-suite with a parent bed. 60 critical care beds, 93 day beds, 22 operating theatres including dedicated cardiac, neurosurgery and orthopaedic suites. BDP won the design competition with O’Connell Mahon. Arup and O’Connor Sutton Cronin carry the engineering. BAM Ireland was appointed main contractor in 2016 and Jones Engineering holds the M&E package. The design-stage BREEAM rating is Excellent.

The numbers that get quoted are the cost and the dates. Original budget was EUR 650 million; the current figure including commissioning is about EUR 2.24 billion, roughly 3.4 times the estimate. Original completion was August 2022. The contractual substantial-completion date of 30 April 2026 was the nineteenth date the contractor had put forward, and it was missed. BAM is facing a reported EUR 40 million delay-cost claim.

The number that actually explains the delay is the defects list. At the April 2026 Public Accounts Committee hearing, 106,500 defects were reported outstanding, including dust in ventilation ducting. Sign-off is running at roughly 108 rooms a week. By August 2026, 4,674 rooms had been completed and signed off, about 82 percent, with a further 690 finished and waiting on the design team.

After construction completion there is a commissioning period of roughly seven months before any child is admitted. Patient opening is currently discussed as autumn 2027.

Why It Matters

Every large healthcare job runs a defects process. What is unusual here is the ratio: a project 82 percent signed off with six figures of open items, on a two-stage public works contract, with a client, an operator and a design team all holding separate sign-off authority. Room-by-room certification at 108 a week against 6,150 rooms is a throughput problem, not a workmanship problem, and no additional labour on site fixes it.

For anyone pricing a hospital in Ireland or the UK, the commissioning tail is the lesson. Seven months of activation after the last defect closes is not padding. It is the actual programme, and it is routinely left out of the headline completion date that ends up in the newspapers.
