The greenfield project currently hosts 238,000 tonnes LCE (measured and indicated) at an average 296 mg/L lithium, with progression to full plant construction contingent on an NI 43‑101 reserve, EIA approval, baseline studies and permits. Lanshen will supply integrated EPC, DLE systems and commissioning in exchange for up to 30% of ALESA, alongside Stellantis’ existing 19.9% stake and offtake rights.

Macmahon Underground Pty Ltd has been named preferred mining contractor by the Central Tanami Project Joint Venture between Tanami Gold NL and MGX Resources Limited for the Groundrush exploration decline in the Tanami region. The scope centres on developing an underground exploration decline to access the Groundrush orebody, signalling a shift from surface exploration to underground resource definition drilling. Contractors and suppliers should anticipate demand for decline development services, ground support, ventilation, and underground power reticulation suited to remote, arid conditions in central Australia.

Victoria is expanding metropolitan rail capacity with additional trains and services across the network, following completion of the twin nine‑kilometre Metro Tunnel and five new underground stations in central Melbourne. The rollout coincides with extended free public transport until the end of May and a 50 per cent fare cut from 1 June to 31 December, aimed at shifting more peak‑hour demand onto rail. For civil and rail engineers, higher service frequencies through the new tunnels will stress‑test signalling, power supply and underground station passenger‑flow design.

Queensland Police have recorded more than 10,600 traffic offences statewide since launching Operation Easter Break, a State Government road safety blitz targeting one of the year’s highest-volume holiday travel periods. The campaign focuses on dangerous driving behaviours affecting heavy vehicles and general traffic, supported by the new ‘A Truckie Knows’ resource promoting truck driver safety and their role in road rule compliance. For road and civil contractors, the enforcement surge signals tighter scrutiny around work-zone speed limits, fatigue risks and heavy vehicle interactions on key freight corridors.

Newpave Asphalt has commissioned a new fixed asphalt plant at Warnervale, New South Wales, positioned on the Sydney–Newcastle corridor to supply major road and subdivision works across the rapidly growing Central Coast. The facility is configured for high-output production of dense graded, open graded and stone mastic mixes, and is designed to incorporate reclaimed asphalt pavement and warm-mix additives to cut binder demand and energy use. For contractors, the closer supply point reduces heavy haul distances on the M1 and local arterials, easing logistics and programme risk on large pavement jobs.

Barton Gold has reported high-grade gold intercepts from recent drilling at its Challenger gold project in South Australia, signalling potential extensions to the existing underground ore system. The campaign targeted previously underexplored zones adjacent to historic workings, using diamond and reverse circulation drilling to test down-plunge and along-strike continuity of known lodes. For mine planners and geotechnical teams, the results point to possible life-of-mine extensions and the need to reassess ground conditions and stope designs around newly defined high-grade shoots.

Ora Banda Mining has reported a new round of high-grade drill results from the Waihi project’s Golden Pole prospect in Western Australia, confirming potential for a fast-tracked open-pit development. Intercepts from reverse circulation and diamond drilling show narrow but high-grade gold zones close to surface, supporting rapid conversion to JORC-compliant resources and early ore feed to the nearby Davyhurst processing plant. For geotechs and mine planners, the shallow mineralisation and existing plant capacity point to short lead times for pit design, geotechnical modelling and permitting.

Rox Resources has reported new high-grade gold intercepts outside the current definitive feasibility study mine plan at the Youanmi gold project in Western Australia, signalling potential to extend the planned underground and open-pit mining inventory. The discovery sits beyond the existing resource envelope defined in the DFS, which already targets redevelopment of historic workings and existing processing infrastructure on site. For geotechnical and mine planners, the step-out mineralisation may require updated pit shells, revised stope designs and additional drilling to constrain geometry, continuity and ground conditions.

Magnetic Resources has lodged additional documentation with Western Australia’s Department of Mines, Petroleum and Energy to progress approvals for its Lady Julie gold project near Laverton, consolidating the development pathway alongside its nearby Hawks Nest tenements. The submission advances permitting for open-pit operations targeting shallow, high-grade oxide and transitional mineralisation that can be trucked to existing regional processing plants rather than requiring a standalone mill. For mine planners and geotechs, the move signals likely near-term work on pit design, geotechnical stability assessments and haulage route optimisation across the Laverton greenstone belt.

Heidelberg Materials has commissioned a converted Class 08e battery electric shunting locomotive for Whatley Quarry, the first electric shunter to operate at any UK quarry. Rebuilt by Positive Traction from a withdrawn diesel unit, the loco uses six Powerpod battery packs providing 600 kWh of energy and up to 50% more tractive effort than the original configuration. The deployment supports Heidelberg’s target to cut delivery transport emissions by 15% by 2030 from a 2019 baseline, signalling practical zero‑emission options for heavy rail movements on quarry sites.

Duraproducts has appointed Ned Birley as general manager for kerbing solutions after its Durakerb recycled polymer kerb gained updated BBA HAPAS certification for use across the UK national highways network. Polymer kerbs are now formally included in the National Highways Manual of Contract Documents for Highway Works, removing a key specification barrier versus traditional concrete units. Birley, formerly head of commercial UK at Kelly Bros International with prior roles at Polypipe and USL Group, will target local authorities, housebuilders and term maintenance contractors to expand polymer kerb adoption.

Sovereign Network Group has appointed 22 contractors, including Galliford Try, J Murphy & Sons, Wates, McLaren Construction and Vistry Partnerships, to a new Contractor Framework for Affordable Homes under its 10‑year £10.9bn investment programme. The 12‑lot framework, with a construction management lot in each region, will support both high‑rise new‑build and regeneration schemes across SNG’s operating areas. SNG targets delivery of 25,000 new homes, signalling a substantial pipeline of medium‑ to high‑density residential projects for civil, structural and building services teams.

Jack Cotterill Tree Services has renewed its fleet with three FUSO Canter 3c13 3.5‑tonne trucks supplied by Mertrux Truck & Van’s Derby branch and fitted by Brooks Engineering with high‑sided tipper bodies and large lockable toolboxes for arboricultural work. The compact footprint of the Canters is being used to access constrained residential and urban sites where turning space and verge loading are limited. Cotterill reports consistent reliability with minimal maintenance, while the modern bodywork and finishes are being used deliberately as part of the company’s on-site branding.

Prefab drainage and water supply systems from Polypipe Building Services cut installation times on the Leeds Sky Gardens tower, with Briggs Forrester Living reducing drainage riser installation from 73 hours to nine hours and slashing modular plantroom on-site assembly operations by 93.5%. The 284-apartment scheme on a constrained 40,500 sq ft brownfield site used 13 off-site prefabricated plantroom sections, craned directly to each floor and joined with just ten electrofusion couplings to simplify logistics and lifting. Polypipe’s Advantage service supplied a complete HDPE-based system using Terrain FUZE, Terrain PAPA, MecFlow Fusion and MecFlow Press, achieving fire classification B-s1,d0 and integrated leak detection.

Finning Power Rental has launched a rebuild programme for its large rental generators, starting with a 1000kVA Cat XQ1000 unit powered by a C32 engine at its Dublin facility and targeting 15 high-capacity units, including 1000kVA, 1500kVA and 2000kVA sets, in 2024. Each generator undergoes a zero-hour engine overhaul, full alternator rewind and component-level assessment of the engine, alternator, cooling pack and container to determine repair versus reuse. The aim is to secure another 12–14 years of operational life per unit, improving fleet availability for short-notice temporary power while cutting lifecycle emissions and material use.

RICS has launched CLEAR – the Coalition for Life Cycle Emissions Alignment and Reporting – at the Sustainable Buildings and Construction Summit in Lausanne to harmonise whole-life carbon measurement across the global built environment. Co-founded with the World Business Council for Sustainable Development and the Global Building Data Initiative, and sponsored by Autodesk, CLEAR will analyse existing methodologies, resolve inconsistencies and create a globally applicable assessment and reporting framework. The coalition, involving firms such as AECOM, Arcadis, Heidelberg Materials and Morgan Sindall, will provide practical tools, technical resources and an online platform to standardise carbon data for design, procurement and asset management decisions.

Europe’s data centre build-out is shifting to campus-scale schemes, with individual sites routinely designed for tens of megawatts and some projects now exceeding 150MW of IT load. Developers are pushing high‑density layouts, dual 132kV grid connections and large‑scale backup generation to secure power resilience while leaving space and structural capacity for future rack loads and cooling upgrades. For civil and M&E designers, the focus is on modular power blocks, flexible chilled‑water or direct‑to‑chip cooling corridors, and foundations that can accommodate phased vertical expansion.

A former Department for Transport Operator non-executive director has raised concerns that the £2bn fleet of HS2 trains ordered by HS2 Ltd may be too long for parts of the planned network and existing classic lines. The warning centres on platform interface risks, potential clearance issues at legacy stations, and the operational impact of running extended-length units through junctions and constrained approaches. Any need to shorten sets or modify platforms would add cost, complicate timetable planning, and affect capacity assumptions built into HS2’s current infrastructure design.

Finland has opened its longest and tallest bridge, a new cable-stayed structure in Helsinki designed as a major urban landmark and key transport link. The bridge uses stay cables to carry long main spans with a minimal pier footprint, improving navigation clearance and reducing foundation works in the water. For designers and contractors, the project signals continued demand for complex cable-stayed solutions in Nordic climates, with associated challenges in ice loading, wind behaviour and long-term cable maintenance.

Leicestershire-based True Group has unveiled a rainbow-wrapped Komatsu 8t excavator to raise funds and awareness for Rainbows Hospice for Children and Young People. The machine, used on live construction and civils sites across the Midlands, will act as a mobile billboard, carrying hospice branding and donation information to contractors, clients and the public. For site teams and plant managers, the initiative shows how standard 8t hire equipment can be leveraged for community engagement without affecting operational deployment or specification.

Tunnelling has begun on Toronto’s £16bn Ontario Line, a 15.6km rapid transit scheme billed as the largest subway expansion in Canadian history, with tunnel boring machines now starting a 6km drive beneath the city’s downtown core. The alignment will run fully separated from existing subway infrastructure, requiring complex urban tunnelling logistics, utility diversions and settlement control in densely built conditions. For geotechnical and civil teams, key issues will include ground movement monitoring, protection of high-value structures and managing vibration and noise constraints in central Toronto.

UK Power Networks has achieved platinum certification for diverting 99.4% of its recoverable construction and operational waste from landfill across its electricity distribution activities. The utility manages spoil, concrete, cable, metals and substation demolition arisings from network upgrades and maintenance through segregation, recycling and recovery rather than disposal. For civil and cable contractors working on UKPN frameworks, the standard effectively makes high waste recovery rates a contractual norm, influencing site logistics, materials selection and reuse of excavated materials.

Finning Power Rental has launched a rebuild programme for its large rental generators to boost fleet availability as demand for temporary power rises on major infrastructure and construction sites. Refurbishing high-capacity units rather than procuring new sets can shorten lead times for projects needing multi‑megawatt standby or prime power, such as tunnelling works, bridge replacements and data centre builds. For site engineers, more reliable access to containerised diesel or gas generators should reduce outage risk during grid connections, phasing works and emergency bypass operations.

Zoomlion Heavy Industry has expanded global deployment of its ultra-large hydraulic excavators and intelligent mining equipment, targeting large-scale, high-efficiency open-pit operations. The line-up centres on ultra-large excavators above the 100 t class paired with autonomous or semi-autonomous haulage and fleet management systems, integrating high-precision positioning, real-time health monitoring, and remote diagnostics. For mine operators, the package signals increasing competition to established OEMs in ultra-class fleets and may influence choices on interoperability, maintenance strategies, and digital platform integration.
