CPD — Continued Prolonged Delays

Update Report: 30 June 2026

Eight Weeks On — What Has Changed

Published: 30 June 2026 | Previous report: 5 May 2026 | Author: Kevin Barry BSc(Hons) MRICS | Category: Latest News

The CPD register is a live document. Since the May 2026 launch post, the dashboards have been updated continuously — new audit reports, ministerial statements, committee hearings, and court rulings have all generated material changes across every jurisdiction. This update summarises what has moved, and in which direction, in the eight weeks since first publication.

The clocks have not stopped. Across seven jurisdictions and 280 schemes, BCIS construction inflation continues to accumulate at a combined rate exceeding £150 per second on the GBP portfolio alone, with Australia adding a further A$161.89 per second. Every item below represents a scheme where the public record has changed. None of it was corrected by a minister volunteering the information unprompted.

Northern Ireland — DETERIORATING ↓

The A5 Western Transport Corridor is approaching its nineteenth year of delay. The Court of Appeal hearing on DfI’s climate-compliance appeal took place 25–26 June 2026 — the same week as this report. The legal block on construction remains in place; Sinn Féin have indicated openness to amending climate legislation as a fallback, but no date for construction has been set. Not a metre of road has been built.

Separately, DfI launched the Section 1 SAR2 (Newbuildings–Sion Mills, ~15km) public engagement, open until 7 July 2026, indicating that design work on Section 1 continues in parallel with the legal block on Sections 2–3. It is activity without construction.

York Street Interchange delivered the starkest assessment of the period. At the NI Assembly Infrastructure Committee on 17 June 2026, a member observed: “if you looked at York Street 10 years ago and you looked at it now there is no difference.” Officials confirmed the scheme is unlikely to start for another 11 years without additional funding. Development fees alone have consumed £6.7m of the £26m spent to date.

No new schemes have been funded. The delay clock runs at £10.35 per second.

The National Children’s Hospital remains the defining unresolved story of Irish public infrastructure. The contractor, BAM, has missed 19 internal deadlines. On RTÉ Prime Time on 18 June 2026, the Minister declined to give a fixed opening date — the description “end of summer 2026” was offered but not confirmed. The total cost is now above the €2.24bn Government-approved baseline following conciliator awards; no new approved total has been published.

On the positive side, MetroLink continues to advance. The M500 PPP — described as the largest public-private partnership ever launched in the state — commenced pre-qualification on 1 May 2026 at an estimated €7.3bn NPV for the build and 25-year operations contract. Luas Finglas is now confirmed to commence construction 2028 (Irish Times, 22 June 2026). The Western Rail Corridor is in active procurement, with a contractor appointment expected summer 2027 and construction from 2028, targeting completion 2031.

The ROI portfolio carries the highest confirmed overrun rate of any jurisdiction — 123.7% across 40 schemes — and the clock runs at €36.13 per second.

Scotland’s most significant movement in the period is the Monklands Hospital halt. Ministers confirmed on 26 June 2026 that the project has been stopped for a comprehensive redesign. Cost has risen from £1.344bn to £2.1bn — a £756m increase on a single hospital — with no revised delivery timeline confirmed. (Source: Angela Constance, 26 June 2026; Construction Enquirer.) Scotland’s CPD index already sits at 63 — Critical, the lowest of all seven jurisdictions. This event alone would push it lower if recalculated.

Against that, the Ferguson Marine ferries finally reached a milestone. Glen Rosa completed engine start in June 2026, with a Q4 2026 handover target now credible. Status has moved from Significant Delay to Minor Delay — a rare positive signal in the Scottish portfolio. The A9 Dualling framework of £1.94bn was launched on 4 June 2026 across five sections, with 2035 delivery milestones.

Scotland’s delay clock runs at £3.22 per second.

Wales — MIXED →

Two significant movements in opposite directions define Wales in June 2026. The Port Talbot Electric Arc Furnace — the centrepiece of the £1.75bn green steel transition — is now facing up to a one-year delay due to electricity grid connection issues. National Grid cannot connect the EAF to the grid on the original schedule (ITV Wales / Guardian, 8 June 2026). A fire on site on 15 June 2026 is under investigation; the programme impact is not yet confirmed. Status has moved to Significant Delay.

In contrast, the Velindre Cancer Centre is demonstrably moving. The tower crane was dismantled in June 2026 following completion of the structural frame — a concrete construction milestone — with extended working hours approved through July 2026 to maintain programme. Status has been upgraded to Minor Delay. Opening remains spring 2027.

Wales holds the lowest cost performance score of all seven jurisdictions (CPD-C: 45). The delay clock runs at £1.61 per second.

London — MIXED →

The Lower Thames Crossing added a further £174m to its confirmed public funding envelope (Guardian, 8 June 2026), bringing the estimated total cost to approximately £10.774bn — against an original announced cost of £6bn. The private financing gap of approximately £7.1bn remains unsecured. Early construction works began March 2026.

The Piccadilly Line upgrade recorded its first genuine milestone in years: new Siemens Inspiro trains completed first passenger rides in June 2026 after years of software integration failures. Full fleet rollout continues through December 2026 to June 2027. Status has moved from Significant Delay to Minor Delay.

The Four Lines Modernisation (Circle, District, Hammersmith & City, Metropolitan) continued to cause major weekend disruptions in June 2026 — a reminder that the upgrade programme, while progressing, remains deeply embedded in the network’s operating constraints.

London’s delay clock — updated to reflect the revised LTC cost — now runs at £18.32 per second on active construction overruns. Stranded Value across the London portfolio stands at £9.78bn.

England — MIXED →

The HS2 Phase 1 ministerial reset on 19 May 2026 confirmed what the CPD register had been tracking for months: new cost range £87.7–102.7bn in 2025 prices — roughly double the previous government baseline. First services from Old Oak Common to Birmingham are now expected May 2036–October 2039, against an original 2026 opening. Speed has been reduced from 360km/h to 320km/h. On 24 June 2026, the first structural steel beams were lifted at Birmingham Curzon Street station — a physical milestone on a project whose political story has dominated the period.

Hinkley Point C recorded a significant construction milestone: Big Carl lifted Unit 2’s inner dome into position on 29 May 2026, with Unit 2 progressing approximately 30% faster than Unit 1 at the equivalent build stage. At a confirmed cost of approximately £48bn (current prices), HPC remains the largest single cost increase of any scheme in the tracker — but it is being built.

TRU (Transpennine Route Upgrade): Dewsbury and Batley road improvement works were completed in May 2026; the Morley–Dewsbury line blockade ran 30 May–27 June 2026 for overhead line installation and track upgrades.

Sizewell C is moving preparatory and logistics works offsite amid a growing nuclear skills crisis — with HPC, SZC, and the submarine programme simultaneously competing for the same specialist workforce. The NAO’s first full assessment (19 May 2026) set the baseline cost at £38.2bn, capped at £47.7bn, with electricity from 2038.

England’s delay clock runs at £114.88 per second. Stranded Value stands at £16.29bn.

Australia — DETERIORATING ↓

Australia’s most significant development of the period is the effective termination of Inland Rail. The Federal Government confirmed in early June 2026 that the railway will not reach Brisbane as originally planned — truncated at Parkes in central New South Wales. Cost assurance by ACIL Allen confirmed the full Melbourne–Brisbane cost exceeded A$45bn, up from the 2015 business case estimate of A$9.9bn and a 2019 budget of A$16.4bn. Only the southern section (Beveridge, VIC to Parkes, NSW) will proceed. This is the most consequential single scheme cancellation in the entire 280-scheme register.

The Suburban Rail Loop East (SRL) saw A$14bn committed and tunnelling is scheduled to commence in 2026, with trains targeted for 2035. A significant delivery risk has emerged: the Victorian opposition has pledged to pause SRL ahead of the November 2026 state election. Should the government change, the project’s programme is materially at risk.

Melbourne Airport Rail recorded a genuine positive: Stage 1 (West Footscray to Albion, A$4.1bn) entered construction in February 2026. The airport terminal section — from Sunshine to the terminal — has no construction contract or confirmed funding, and full opening remains 2033, four years late.

Australia’s delay clock runs at A$161.89 per second. The Inland Rail termination alone represents a confirmed scope loss of approximately A$28bn of originally planned infrastructure.

What This Tells Us

Eight weeks is a short interval. In infrastructure terms, it is almost nothing. And yet across seven jurisdictions, every one of these updates — a court hearing, a ministerial non-answer, a grid connection problem, a crane dismantled, a beam lifted — represents the granular reality of how public infrastructure actually moves. Or does not move.

The most significant single event of the period is the Inland Rail termination in Australia: a project conceived in the 1990s, funded in 2017, and now effectively cancelled for the section that justified it — the Brisbane connection. The second most significant is Monklands Hospital in Scotland: a £2.1bn project that has been stopped for redesign, with no revised timeline, within days of this report’s publication. In both cases, the full cost of the original decision — the premature announcement, the undercooked business case, the optimism bias — is now on the public record.

The Piccadilly Line trains running and Velindre’s crane coming down matter too. Not because they offset the failures, but because they show the difference between schemes with active contracts and committed contractors, and schemes held in political limbo. The distinction is consistent across all seven jurisdictions. Where there is a contractor and a site, there is progress — however late and however expensive. Where there is neither, there is only the clock.

The register is updated and all nine dashboards are live.
