    Thieving builder ordered to repay £190k: asset security lessons for contractors

    A builder who stole nearly £85,000 of construction machinery and used company funds to buy a high‑performance car has been ordered to repay over £190,000 within three months or face jail. The confiscation order, made under proceeds of crime legislation, more than doubles the value of the original thefts to capture wider unlawful gains. Contractors and plant hirers are likely to note the court’s willingness to treat misused company accounts and stolen site equipment as recoverable criminal assets on this scale.

    Sizewell C boosts Balfour Beatty order book: delivery and risk notes for engineers

    Balfour Beatty is projecting a 20% order book increase to about £22bn for 2025, driven by £3bn of work on the Sizewell C nuclear power station within the main contracting team alongside the Bylor JV of Bouygues and Laing O’Rourke. Power generation orders total £3.5bn this year, while other wins include Rolls-Royce’s sole-contractor fissile construction framework and a £162m contract for the Dunard Centre concert hall in Edinburgh. Revenue is expected to rise only around 5% from £10.0bn, but underlying PFO should exceed 2024’s £252m.

    £28bn energy grid work: RIIO-3 investment and delivery risks for project teams

    Energy network companies have been cleared by Ofgem to invest £28bn between April 2026 and March 2031 under the RIIO-3 price control, with £17.8bn for maintaining Britain’s gas networks and £10.3bn for strengthening the electricity transmission system across 80 projects. The package includes staged release of funds and clawback mechanisms, with Ofgem imposing an explicit “efficiency challenge” and on-time, on-budget delivery requirements on monopoly operators. Ofgem estimates the net impact on consumer bills at about £30 a year by 2031, framing this as the cost of grid resilience and capacity for new industrial loads.

    UK Construction PMI slump to 39.4: delivery, cost and risk signals for project teams

    UK construction output fell sharply in November as the S&P Global UK Construction PMI dropped to 39.4 from 44.1 in October, its lowest level since May 2020, with new orders contracting at a rate last seen in early 2009 outside the pandemic. Housing (index 35.4), commercial (43.8) and civil engineering (30.0) all recorded their steepest downturns in five-and-a-half years, while employment declined for an 11th consecutive month and subcontractor usage and buying activity both fell markedly. Softer demand improved supplier performance but input costs for electrical components, copper products and insulation continued to rise, keeping margin pressure high despite more manageable inflation.

    Crown Prince gold mine outperforms: design and scheduling notes for planners

    New Murchison Gold’s Crown Prince gold mine has recorded a strong start, with initial production performing above feasibility study forecasts at the historic Murchison operation in Western Australia. The project, centred on the Crown Prince deposit near Cue, is ramping up conventional open-pit mining and CIL processing of near-surface ore, with early mill throughput and head grades exceeding modelled assumptions. For mine planners and geotechs, the outperformance suggests more favourable orebody continuity and grade distribution than block models predicted, potentially supporting revised pit designs and mine schedules.
