Enabling works have started on Hartwell’s £50m regeneration of the 8.4-acre former Hartwells Garage site on Newbridge Road, Bath, including removal of the old damaged forecourt canopy and detailed pre-construction surveys. The Allford Hall Monaghan Morris-designed scheme will deliver 104 apartments, a 186-bed student block, new A1/A3 commercial units and landscaped public realm on the brownfield plot, vacated in 2019. Hartwell is working with Walsingham Planning, Ridge, Stantec, IMA Transport Planning and Aspect Ecology, with the main contractor still to be appointed.

Work has restarted on two nearly complete residential blocks at Southwark’s St Saviours Estate in Bermondsey after ARJ Construction, which had finished about 90% of the works, went into administration in April 2024. Newly appointed contractor Bloom Construction, founded in 2023, is now tasked with delivering 40 council homes at the Fendall and Maltby site by spring 2026. The remaining scope covers final fit-out, M&E commissioning, contaminated soil removal, external works and landscaping, lift installation, play equipment and full building control compliance.

The Welsh government has launched a Built Environment Mission Statement and a Digital Action Plan for Construction, committing to project bank accounts (PBAs), prioritising retrofit over new build, and promoting offsite prefabrication of large components. Developed with Constructing Excellence in Wales, the digital plan targets productivity gains, better project delivery and “future‑ready” skills, backed by a forward pipeline of public sector contracts to give earlier visibility of workload. The Social Partnership and Public Procurement (Wales) Act 2023 now makes socially responsible construction procurement a statutory duty, requiring public bodies to agree well-being objectives with trade unions or staff representatives.

A government-commissioned Nuclear Regulatory Taskforce has issued a 162-page Nuclear Regulatory Review 2025 with 47 recommendations to cut delays and costs on projects such as Hinkley Point C, whose first reactor has slipped from a 2025 to at least a 2029 start-up. Led by former Office of Fair Trading chief executive John Fingleton, the taskforce calls for a unified Commission for Nuclear Regulation, a ‘one‑stop shop’ for approvals, and merging the Defence Nuclear Safety Regulator into the Office for Nuclear Regulation. The review targets “unnecessary over‑specialisation” in components from bolts to cranes, urging greater use of commercial off‑the‑shelf solutions and clearer risk proportionality to save tens of billions in decommissioning and improve constructability.

RSK has acquired Octavius Infrastructure from Sullivan Street Partners, moving the formerly consultancy-focused group into tier one main contracting across UK rail and highways, with Octavius’ 700 staff retained under chief executive John Dowsett. Octavius reported £322.9m turnover and £8.6m pre-tax profit to 31 March 2025, while RSK turned over £2.24bn but remained loss-making after 11 acquisitions in the year. Current Octavius schemes include Ryde Pier and Waterloo Station roof refurbishments, new stations at Okehampton and Charfield, and the A46 Walsgrave and A140 Long Stratton Bypass upgrades.

Three major National Highways schemes on the A47 near Norwich are being delivered in parallel to cut delays and collisions while doubling as training grounds for early-career engineers and apprentices. The projects include junction upgrades and dual carriageway sections designed to current DMRB standards, with works sequenced to maintain live traffic and integrate complex traffic management, drainage and earthworks phasing. Contractors are using the schemes to give graduates supervised experience in NEC contract management, temporary works design and digital construction tools such as BIM-based clash detection.

Cooling design for hyperscale data centres is becoming a critical constraint as AI workloads drive power densities well beyond traditional 5–10kW per rack, forcing operators to consider liquid cooling, rear-door heat exchangers and direct-to-chip systems. Engineers must balance evaporative and adiabatic cooling against tightening water-stress and abstraction limits, particularly in regions already facing summer drought restrictions. Site selection, pipework routing, thermal storage and integration with district heating networks are emerging as key civil and MEP interfaces, with planning authorities increasingly scrutinising water-use intensity alongside PUE.

Heavy rainfall in Sri Lanka’s Central Province triggered a fatal landslide that killed four people when a saturated slope above a narrow local road collapsed onto passing vehicles, according to the Disaster Management Centre. The failure followed several days of intense monsoonal rain that exceeded typical seasonal totals, with local authorities already recording multiple smaller slope instabilities and debris flows in adjacent hill districts. Geotechnical teams are now prioritising rapid slope inspections, temporary drainage and toe protection on weathered residual soils along rural road corridors that lack engineered retaining structures.

City of Bendigo’s Coordinator GIS & Asset Information, Paul Nicholson, is deploying GBM Konect, a mobile field management app, to overhaul how road and drainage assets are captured and maintained in the field. Konect’s flexible data model allows crews to map linear assets, attach photos and condition data offline, and sync directly to the council’s central GIS rather than relying on point-only, office-based systems. For civil and asset engineers, this means faster defect logging, fewer data transcription errors, and more reliable spatial information for pavement and drainage renewal planning.

Civilcast is launching a new range of custom precast road pits that Product Development Manager Brian Lee says are engineered for higher load capacity and durability in major road and urban projects. The pits are tailored to project-specific geometry and cover arrangements, aiming to reduce on-site adjustments and installation time compared with standard catalogue units. For designers and contractors, the focus is on improving long-term performance of buried drainage and services structures that typically carry significant traffic and environmental loads but receive limited design attention.

Roads Australia will rebrand as Transport Australia following member approval at its recent Annual General Meeting, signalling a shift from a roads‑only focus to a broader, multimodal transport remit. The peak body, which has spent more than a decade convening governments, contractors and consultants on issues such as road funding models, asset management and decarbonisation, will now explicitly cover rail, ports and integrated transport networks. For civil and transport engineers, this points to policy forums and guidance increasingly framed around whole‑of‑network planning rather than discrete road projects.

Construction has started on the first project in the $500 million Queensland Beef Roads programme, with a $47.5 million early works package sealing a priority section of the Clermont–Alpha Road about 89 kilometres north of Alpha in the Barcaldine region. The staged upgrades will progressively seal and strengthen key cattle and freight corridors that are currently partly unsealed, improving all‑weather access for high‑productivity road trains. For pavement designers and geotechnical teams, the focus will be on durable surfacing and subgrade performance under heavy axle loads and seasonal flooding.

BHP has made a fresh approach to acquire Anglo American less than three weeks before Anglo and Teck shareholders vote on their proposed US$53 billion merger, injecting new uncertainty into one of the sector’s largest pending deals. The move could reshape ownership of Anglo’s copper, iron ore and metallurgical coal assets, including operations in Chile, Peru and South Africa that are central to long‑term steel and energy-transition demand. For mine planners and project developers, a BHP–Anglo combination would likely trigger portfolio rationalisation, asset sales and revised capital allocation across multiple jurisdictions.

Researchers at New York University Abu Dhabi report Curiosity rover evidence that liquid water once flowed beneath aeolian dunes in Gale Crater, forming cemented crusts and polygonal fracture networks in fine-grained sandstones. High-resolution Mastcam and ChemCam observations show cross-bedded units with indurated tops and moisture-related diagenetic features consistent with shallow subsurface flow rather than surface runoff. For planetary geotechnics, the work implies past groundwater-driven cementation, altered shear behaviour of dune-derived sediments, and more complex subsurface stratigraphy relevant to future drilling and in situ construction on Mars.

A new algorithmic framework from MIT identifies the smallest “core” dataset needed to guarantee optimal solutions in structured decision-making problems such as geotechnical design under uncertainty. The method uses combinatorial optimisation to strip large datasets down to a minimal subset that still preserves the same optimal decision, reducing computation while maintaining solution quality. For geotechnical engineers running probabilistic slope stability, foundation or tunnel support analyses, this could cut Monte Carlo or scenario runs without sacrificing reliability in design outcomes.

Underground conversion drilling at Lundin Gold’s Fruta del Norte South deposit in Ecuador has intercepted 5.2 metres grading 491.62 g/t gold from 40.6 metres depth, confirming locally bonanza-grade mineralisation near existing workings. The shallow intercept, from underground drilling rather than surface, suggests potential for rapid incorporation into the current mine plan with limited additional development. For geotechnical and mine planning teams, the result supports tighter stope design around high-grade shoots and may justify re-optimising ground support and sequencing in this sector of the orebody.

About 15,000t of concrete from the demolished turbine alternator plinths at Sizewell A is being crushed and graded for reuse as sub-base material for foundation platforms at the Sizewell C nuclear project. Using this on-site recycled aggregate will reduce primary quarried aggregate demand and heavy lorry movements to the Suffolk coast site, cutting embodied carbon and local traffic impacts. Geotechnical teams will need to verify grading, compaction behaviour and durability of the recycled concrete to meet nuclear foundation performance and QA requirements.

Construction of the second Gotthard road tunnel in Switzerland involves driving a parallel bore through hard Alpine rock and significant fault zones while working within a tightly constrained existing portal and operational highway. Engineers must stage excavation and lining works to avoid disrupting the first tunnel, manage faulted ground with targeted reinforcement and waterproofing, and sequence logistics in limited laydown and access areas. Ambitious circularity targets are pushing reuse of excavated rock in concrete and aggregates, demanding strict material characterisation and on-site processing strategies.

Plans to widen and reconfigure two major roundabouts on the A52 south of Nottingham have been signed off by the secretary of state following a public inquiry, allowing the final phase of the corridor’s long‑running upgrade to proceed. The scheme will increase circulatory and approach lane capacity on both junctions and introduce improved pedestrian and cyclist crossings. Designers will need to manage tie‑ins to existing A52 dual carriageway geometry, maintain traffic flows during construction and address drainage and pavement strengthening for higher traffic loads.

Ground engineering and piling for the replacement of the 60-year-old Clifton Bridge over the M6 in Cumbria have been completed by Cementation Skanska, allowing the project to move into the bridge installation phase. The works prepare foundations for a new structure spanning the motorway, replacing ageing 1960s infrastructure that carries local traffic over one of the UK’s busiest north–south corridors. For geotechnical teams, the milestone signals that substructure risks are largely retired and attention will now shift to superstructure erection and traffic management constraints over live motorway lanes.

Knighthead Capital Management has unveiled concept images for a new 62,000‑seat Birmingham City FC stadium within the proposed Birmingham Sports Quarter at Bordesley Green. The large-capacity bowl will be the centrepiece of a wider mixed-use redevelopment, with the scale implying major transport, geotechnical and utilities upgrades on a constrained urban site. Early-stage design decisions on structural framing, roof span and crowd circulation will be critical for meeting Premier League and UEFA standards while managing buildability and phased construction around existing infrastructure.

BS 30417 introduces the UK’s first formal standard for inclusive PPE sizing and fit, moving away from legacy designs based on a single “average man” template. The standard sets out anthropometric measurement guidance, fit-test protocols and size-range requirements so items such as fall-arrest harnesses, hi-vis garments and safety footwear can accommodate women, ethnic minorities and workers with non-standard body shapes. For contractors and asset owners, it signals future procurement specifications where PPE suppliers must evidence compliant size ranges and documented fit assessments rather than offering limited S–XL ranges.

A 15m-diameter vertical shaft sinking machine, claimed as Europe’s largest of its type, has started excavating at National Grid’s Tilbury site to construct a new cable tunnel beneath the River Thames between Tilbury and Gravesend. The shaft will form the main access and cable route for replacing a 1960s transmission tunnel, enabling modern high-voltage circuits to be installed at greater depth and with improved flood resilience. Contractors will need to manage large excavation volumes, groundwater control and segmental lining tolerances for a very wide, deep vertical shaft in complex Thames alluvium and terrace gravels.

The UK High Court has found BHP Group liable for the 2015 failure of the Fundão tailings dam in Mariana, Brazil, which killed 19 people and polluted around 600km of the Rio Doce and coastal waterways. The ruling concerns the collapse of an upstream tailings structure jointly owned via Samarco, which released tens of millions of cubic metres of iron ore waste and devastated multiple downstream communities. The judgment opens the door to large-scale civil claims in England, sharpening scrutiny of tailings design, monitoring and governance for UK-listed miners operating overseas.
