A damning review has found every project in a state's hospital expansion plan is "undeliverable", with costs set to blow out by almost $10 billion.

All 15 projects face delays of up to three years after a "deeply flawed" procurement process by Queensland's former Labor government, the review states.

Originally slated to cost $9.8 billion, the projects are expected to balloon out to more than $17 billion after expansion and new builds were announced without business cases.

The independent review, headed by Klok Advisory managing director Sam Sangster, was tabled on Wednesday, exposing flaws in the former government's hospital expansion program.

"In their current form, they don't fit in those budgets by any measure," Mr Sangster told a Major Contractors Association breakfast in Brisbane on Wednesday.

The former government had made a "laudable response" to increase capital funding for hospitals but rushed the planning process, he said.

"It's pretty clear that the procurement strategy choice of the managing contractor and the risk allocations that were chosen to be put in place were deeply flawed ... and ignored market realities," Mr Sangster said.

He said a number of projects were awarded in September 2024, days before the election caretaker period, requiring a 70 per cent budget increase.

"I am somewhat challenged also that the procurement of those projects was done in about 12 to 14 days - a monumentally short period of time for projects of that scale," Mr Sangster said.

"The projects that have not yet moved into construction, in my view, are undeliverable in their current form."
