Delivery performance
How infrastructure projects held to their budgets and their timetables. Every figure comes from the contract terms and costs recorded on each section, and a section appears only once the data supports the claim.
Measured on 213 sections: 3 with an estimate-to-outturn comparison, 6 against the contract award, 35 delivered with a contract timetable, 5 still running.
The gaps are missing data, not clean records. A section without a recorded outturn cost or contracted duration cannot be measured, so it is left out rather than assumed on budget.
All costs restated in 2025 prices. In-progress delays measured as of Sep 2026.

What it cost
The best cost figure each section has: the outturn where one was published, otherwise the signed contract value, otherwise the pre-tender estimate. To rank them together each figure is restated into common prices and then converted to euro at that year's exchange rate. A section whose currency or price year falls outside those tables keeps its recorded cost but has no comparable figure, and sorts to the bottom.
Most expensive per kilometre first until you sort.
By contractor
Builders only, since a construction overrun belongs to whoever built the thing. Joint-venture work counts toward each partner, and name variants are resolved to one firm. Firms with a single section are left out.

Method
Costs carry the price year they were quoted in, and both sides of every comparison are restated into a common year before the percentage is taken, so an estimate made in 2013 is never measured directly against money spent in 2023. Costs recorded in different currencies are restated first and then converted to euro at that year's annual average exchange rate, in that order: converting first would use a rate from one year against prices from another.
Schedule slip uses the contract as the baseline rather than a press announcement, because that is the commitment the public paid for and the only baseline present for sections whose announced dates were never recorded. Negative values mean early.
