NI — CPD-C: 🔴 Red (63) | CPD-D: 🔴 Red (75) | Combined: 69
NI’s delivery picture remains the defining failure — A5 legally blocked (Court of Appeal 25–26 Jun 2026), York Street confirmed at least 11 more years away (NI Assembly Committee, Jun 2026), Casement Park funding gap unresolved. Not a metre of A5 built in nearly two decades. The South is building things, however expensively. The North is mostly still announcing them.
ROI — CPD-C: 🔴 Red (86) | CPD-D: 🔴 Red (85) | Combined: 86
ROI’s crisis is pure cost: every €1 announced has become €2.24 delivered across 40 schemes. NCH has missed 19 deadlines with no confirmed opening date (Jun 2026). But schemes are advancing — MetroLink M500 PPP launched, Luas Finglas construction from 2028, Western Rail Corridor in procurement. The South spends recklessly. The North doesn’t spend at all.
Index methodology — two sub-indices, one combined score.
CPD-C (Cost Index): (avg overrun % × 0.50, capped at 100) + (% schemes >25% over budget × 0.30) + (% with TBC/unknown cost × 0.20).
CPD-D (Delivery Index): (% schemes significantly delayed or paused × 0.50) + (% schemes not yet started × 0.30) + (% with no confirmed construction date × 0.20).
Combined CPD Score = average of CPD-C and CPD-D, rounded to nearest integer.
NI: CPD-C = (100×0.5) + (56.3×0.3) + (18.8×0.2) = 50 + 16.9 + 3.8 = 71. CPD-D = (62.5×0.5) + (12.5×0.3) + (31.3×0.2) = 31.3 + 3.8 + 6.3 = 41. Combined = 56 / 100.
ROI: CPD-C = (95.9×0.5) + (94.4×0.3) + (5.6×0.2) = 48 + 28.3 + 1.1 = 77. CPD-D = (50.0×0.5) + (5.6×0.3) + (11.1×0.2) = 25 + 1.7 + 2.2 = 29. Combined = 53 / 100.
Scores are based on official published data (NIAO, DfI, TII, C&AG, NTA). A score of 0 = perfect delivery. A score of 100 = total systemic failure.
