6,000t capacity giant enables faster construction methodologies across the energy sector Mammoet, the largest global engineered heavy lifting and transport company, has today launched the world’s strongest land-based crane, the SK6000. As populations grow, so do our energy needs. The SK6000 re-defines the scale of human construction, allowing large energy and infrastructure projects to build from bigger pieces, in parallel – reaching first power sooner, and more cost-effectively. The SK6000 has a key role in offshore wind, where fast growth of components in recent years has led to supply chain issues. Lifting 3,000t to a height of 220m, the SK6000 ensures that wind farms in the planning phase today can be safely executed and delivered in the future. In the oil and gas sector, the SK6000 delivers reduced integration times to offshore floating projects, while onshore new build and expansion projects can be delivered with increased uptime. Both scopes then benefit from modular construction techniques that allow critical path components to be simultaneously built offsite anywhere in the world, before transporting to site ahead of installation. As more new-build nuclear plants are greenlit, the SK6000 helps the sector to benefit from similar tried-and-tested construction methodologies – helping projects to reach completion sooner and deliver low carbon energy to communities. The SK6000 has a maximum capacity of 6,000t, utilizing 4,200t of ballast to lift with a maximum ground bearing pressure of 30t/m2. The crane design uses containerization techniques for ease of deployment, and can be transported using shipping containers to any location worldwide. It also offers full electric power capability from battery or supply from the grid, allowing customers to reduce the carbon impact of projects significantly. “This crane is truly a world record feat of engineering, with a production schedule to match”, said Gavin Kerr, Director Global Services at Mammoet. “Hundreds of colleagues have been directly involved with its development across the business. There are very few companies on Earth – if any – that could have brought this crane into reality, and we are immensely proud to be able to do so”. The SK6000 is currently undergoing testing at Mammoet’s Westdorpe facility in the Netherlands, ready for deployment to its first project later in the year.

Last wave of construction starting for the North Portsea Coastal Scheme at Ports Creek

Last wave of construction starting for the North Portsea Coastal Scheme at Ports Creek

Work on the fifth and final phase of the North Portsea Coastal Scheme is set to start in the first week of September along Ports Creek, the northern shore of Portsea Island. The work will include 1.3 km of flood defences with a design consisting of a sloped earth embankment, which provides the required flood defence level, with rock armour towards the creek. Construction company Knights Brown was appointed in August to carry out the work which is set to finish by the end of 2026. Knights Brown previously constructed the first and third phases, meaning they will have completed the majority of work on this valuable scheme. Construction site boundaries will comprise of the area north of the Hilsea Lines moat. Visitors will still be able to access the woodlands known as Foxes Forest on the southern side of the moat. The Portsbridge carpark near Portsbridge roundabout will be closed for the duration of the work. The footbridge leading over the M27 from Peronne Road will be closed for a one-week period in October, to allow a temporary overpass for pedestrians to be constructed. The overpass will remain in place for the duration of the work, maintaining pedestrian access to the footbridge. The footbridge adjacent to the railway line, further east along the creek, will be closed from November 2024 for a period of approximately 12 months (more information will be available when the detailed construction programme is finalised). Diversion routes will be signposted and updates will be available through signage, on social media and the website. As this phase will regenerate an area famous for its green open spaces the focus will be on retaining the natural feel by planting trees, native scrubs and wildflowers, improving paths, and access to the coastal path along the waterfront. New picnic benches, seating, play areas and viewing platforms along the coastal path route will create a more enjoyable environment. The North Portsea Coastal Scheme will also protect the Hilsea Lines by providing a future proof flood defence system, ensuring that this nationally important historical asset will be available for visitors to enjoy for the decades ahead. The project is funded by the Environment Agency and implemented by Coastal Partners on behalf of Portsmouth City Council. Portsmouth City Council Leader, Cllr Steve Pitt said: “We’re very pleased to be working collaboratively with Knights Brown on the final phase of the North Portsea Coastal Scheme. It’s an exciting time as we forge towards completing the final link in this vital £85.9million sea defence project, which is made possible thanks to funding by the Environment Agency.” The scheme as a whole is one of the largest local authority-led coastal flood defence projects in the UK and is crucial for the protection of Portsmouth residents. The defences will safeguard more than 4,000 homes and almost 500 businesses. In total, it covers 8.4km of coastline from Tipner through to Milton. Most of the area is low-lying and many of the current coastal defences were approaching the end of their effective lives.

The future of energy efficiency lies in breaking system barriers – Helvar Senses now commercially available

Helvar, a leading innovator in intelligent lighting solutions, is excited to announce the official commercial launch of Helvar Senses, an advanced environmental sensing solution integrated into lighting controls. Building on insights gained from pilot projects across various industries, including a successful trial with Rejlers in Sweden, Helvar Senses is now available to the broader market. By incorporating smart environmental sensing into its offering, Helvar’s solutions now offer even more opportunities to optimise building performance, sustainability, and occupant wellbeing.  When it comes to enhancing building performance through lighting systems, a crucial element has often been overlooked – the potential to go beyond traditional controls. Lighting systems, which already serve as one of the densest sensor networks within a building, offer a unique opportunity to provide much more than light. With the addition of environmental sensing capabilities – such as monitoring air quality, temperature, humidity, and noise levels – Helvar Senses collects actionable data that can optimise not just lighting but overall building performance. This approach offers a scalable solution that is easier to manage and maintain compared to deploying standalone sensors. By integrating environmental sensing into the existing lighting infrastructure, building operators benefit from a unified system that reduces complexity, lowers operational expenditure (OpEx), and is simpler to maintain over time. By correlating data on occupancy and environmental conditions, building operators can make more informed decisions, leading to significant energy savings and reduced carbon emissions. For instance, integrating HVAC systems with Helvar Senses helps avoid siloed operations and enables better control over energy use by aligning air quality with occupancy patterns. Supporting Sustainability Goals and Building StandardsIn response to increasingly stringent sustainability directives such as the Corporate Sustainability Reporting Directive (CSRD) and evolving building standards like BREEAM, WELL, and LEED, Helvar Senses offers a solution that helps minimise the “performance gap”– the difference between the predicted energy performance of a building and its actual energy usage. By providing real-time data, building operators can adjust systems to ensure that energy consumption is optimised according to real conditions, helping to meet both regulatory requirements and sustainability goals. Helvar Senses allows building operators to monitor key indoor environmental factors and thus better support the wellbeing of occupants. This is particularly relevant as organisations prioritise creating healthier workspaces that promote productivity and comfort. Customer Success with Rejlers  The deployment of Helvar Senses in real-world projects has already produced impressive results. One of these projects is with Rejlers, a leading engineering consultancy who chose to expand their system at their HQ Office in Gothenburg, Sweden. The team opted to include Helvar Senses in their lighting renovation and saw immediate benefits. Nicklas Stenberg, project manager and team leader at Rejlers, explained how the solution has improved their indoor environment: “After expanding the entire system with Helvar Senses, we now have an easy way to check temperatures and air quality inside the premises. Previously, if we felt the air was bad, we would complain without any data to back it up. Now, we can monitor the actual conditions and take action accordingly.”  Helvar Senses is empowering buildings to achieve greater energy efficiency while improving occupant wellbeing. By leveraging data from lighting sensors, Helvar Senses not only optimises lighting and energy use but also supports a healthier and more comfortable indoor environment. As companies strive to meet sustainability directives such as the CSRD, Helvar Senses offers a smart solution that drives measurable progress toward environmental goals.

Ceremony marks the start of work at 2,500-home development in Swindon’s New Eastern Villages

A breaking-ground ceremony has been held to mark the start of construction work at a new village on the edge of Swindon up to 2,500 homes. Senior figures from housebuilder Vistry Group, Sovereign Network Group (SNG) and Swindon Borough Council gathered to formally place the first spade in the ground at Lotmead on Friday 23 August. The development, which is a joint venture between Vistry and SNG, has been planned to include a local centre, two primary schools, sports hub and green space on a 417-acre site to the east of Wanborough Road. Lotmead forms part of the wider New Eastern Villages project which is set to provide around 8,000 new homes alongside a range of new employment, health, retail, education and leisure facilities. Vistry Cotswolds will build 214 homes under its Bovis Homes brand in the first phase of Lotmead, known as King George Park, on a 39-acre parcel of land in the south-western part of the wider site. This will include 153 properties for private sale through Vistry’s Bovis Homes brand and 61 affordable homes for low-cost rent or shared ownership through SNG. The breaking-ground ceremony was attended by Swindon Borough Council leader Jim Robbins, the council’s corporate director for inclusive economy and sustainability James Coulstock, and director of strategic growth Richard Bell. Also in attendance were James Gibson, development director at SNG, and a delegation from the senior management team at Vistry Cotswolds led by regional managing director Supriya Ray. Councillor Robbins said: “I am delighted we have been able to support the UK’s biggest housebuilder, Vistry, in unlocking this site for over 2,000 homes in the New Eastern Villages (NEV) to show that Swindon is leading the way in delivering the housing growth expected by the new government. “Lotmead will see a significant number of new homes, 30 per cent of which will be affordable, and a brand new community in a village setting complete with schools, green open spaces and local facilities delivering on our missions to build a greener and better Swindon. “I look forward to seeing the development take shape as we continue our drive to meet our housing targets so we build the homes our residents will need now and into the future.” Supriya Ray, regional managing director of Vistry Cotswolds, said: “The New Eastern Villages scheme is one of the most significant urban regeneration projects in the UK. This exciting development will not only help to address the country’s housing shortage but also assist Swindon Borough Council’s aspirations to kick start economic growth in the town and wider region. “Lotmead is one of the first villages to be brought forward within the wider scheme, and will therefore have an integral role to play in the formation of this new community. We are proud to be working in partnership with SNG and the council to deliver the new homes and infrastructure which will create a thriving and sustainable neighbourhood where people will want to live. “Our involvement in this massively important project reflects our partnerships-led approach and further underlines Vistry’s position as the UK’s leading provider of affordable mixed-tenure homes.” As part of the planning agreement for the development, Vistry will be providing a significant investment in local services and infrastructure, which it expects to be in the region of £60 million. This will include contributions towards primary and secondary education, healthcare and road improvements. In addition to this, Vistry will be providing allotments, sports pitches, two equipped play areas, a new road, cycle links, and a sports pavilion. James Gibson, Development Director Regional Managing Director West at SNG, said: “This site is a positive step towards delivering our ambitious plans for tens of thousands of good, affordable, new homes that are much needed.

Plans submitted for landmark sustainable canopy at Huddersfield bus station redevelopment

Plans submitted for landmark sustainable canopy at Huddersfield bus station redevelopment

Stephen George + Partners (SGP) in conjunction with AHR has submitted plans for the £20 million redevelopment of Huddersfield’s bus station, fronted by a sweeping 120-metre-long glulam, green roof and Solar PV canopy. The bus station transformation is a partnership between Kirklees Metropolitan Borough Council and West Yorkshire Combined Authority to create an innovative gateway to the revitalised town centre along with enhanced passenger facilities. Explains Alistair Branch, Partner at SGP: “Huddersfield is the largest bus station in West Yorkshire and its redevelopment is a core component in an ambitious series of town centre interventions led by the Council to create a cultural heart for the town centre. The unique canopy structure has a contemporary design, reminiscent of the rolling Yorkshire landscape, elevating the importance of this key transport hub and gathering point within the town centre. “SGP has been involved in the project for several years, developing the canopy from initial concept, through business case approval to the design now submitted for planning approval.” SGP’s design for the canopy and the public realm beneath it was developed through extensive discussions with clients, the local authority and other stakeholders. The proposed canopy design is a simple sinusoidal timber lattice structure supporting a green roof that undulates along the length of the bus station, emphasising key entrances and drawing the eye down from the imposing multistorey car park’s long concrete façade. Office and retail units in the station’s frontages will also be revitalised, delivering a harmonious continuity with surrounding businesses. Continues Matt Beaumont, Associate at SGP: “The canopy uses a glulam lattice to support a mix of sedum roof and solar panel glass to create a light and inviting transition space from the public realm to the bus station itself. The integrated roof lights not only let natural light flow into the area but produce their own green energy, whilst the sedum promotes biodiversity, reducing rainwater runoff and helping improve local air quality. The solar glazing ensures energy generation is visible to users below for educational purposes whilst additionally diffusing direct sunlight.” Beneath the canopy, enhanced public realm extends north towards the taxi ranks and Grade I listed Railway station. A secure, glazed cycle hub for green transport supports the Local Authorities’ commitment to modal shift, linking towns and villages across West Yorkshire and beyond as well as cycle and walking routes to the retail, civic and employment areas within Huddersfield town centre. Concludes Alistair: “As Matt and I are Huddersfield residents, we are immensely proud of our design for Huddersfield Bus Station Canopy. We believe it has balanced sustainability with quality materials and created the landmark gateway to this strategic transport hub that the council and locals want and deserve.” If planning is granted, work is expected to start on site in the summer of 2025.

Balfour Beatty VINCI celebrate key milestone as tunnel boring machine reaches halfway point on HS2’s route into Birmingham

Balfour Beatty VINCI celebrate key milestone as tunnel boring machine reaches halfway point on HS2’s route into Birmingham

Balfour Beatty VINCI’s construction of HS2’s gateway to Birmingham takes a leap forward as the huge 125-metre-long tunnel boring machine (TBM) digging the first bore of the Bromford Tunnel reaches the halfway point. The 1,600 tonne TBM, named ‘Mary Ann’ – the real name of Warwickshire-born author George Eliot – has excavated and built 1.75 miles of the first bore of the tunnel since it started digging from a large underground box in Water Orton last year. Driving around 40 metres underground towards Washwood Heath in Birmingham, the TBM has excavated under the Park Hall Nature Reserve and River Tame and is now passing under Castle Vale. It will continue adjacent to and under the M6 before breaking through at Washwood Heath early next year. An expert tunnelling team have been working around the clock on shifts to operate the TBM, which also builds the tunnel as it excavates. A total of 20,797 concrete segments will be put in place by the machine, making 2,971 concrete rings to form the tunnel. The tunnel’s 47-metre-deep ventilation shaft at Castle Vale marks the halfway point of the TBM. The shaft, which is 18.6 metres in diameter, will feature cross passages which will eventually link to the two tunnels either side to provide ventilation, servicing and emergency access. A ‘headhouse’ will be built on top of the shaft, and the whole structure will be complete in 2027. ‘Elizabeth’, the second TBM – named after Dame Elizabeth Cadbury by local school pupils, started building the tunnel’s second bore in March 2024 and is due to finish her journey towards the end of 2025. The two TBMs will remove 1.87 million tonnes of excavated material, which is being sifted at the on-site slurry treatment plant and reused on nearby sites at the Delta Junction, where a complex network of 13 viaducts is being built. HS2 has built dedicated roads between these construction sites, including an access off the M6/M42 link roads, in order to take lorries off public roads. In preparation for the arrival of the TBMs at Washwood Heath, a huge earthworks operation has been completed by a team of 130 people to build the tunnel’s west portal, which at 22 metres below ground is the deepest of the four tunnel portals on the Midlands section of the HS2 route. The portal is at the start of a 750-metre-long cut and cover structure, which is currently being excavated and built. This is where HS2 trains will emerge from the Bromford Tunnel and travel below ground level, before raising up onto a series of viaducts through Birmingham’s industrial heartland and into Curzon Street Station. Jules Arlaud, Tunnelling Director for Balfour Beatty VINCI said: “Reaching the halfway point on this complex stretch of the HS2 route into Birmingham is a great milestone for our 180-strong tunnelling team. “We’re looking ahead now to delivering the final stages of tunnelling and celebrating the breakthrough of both TBMs at Washwood Heath next year.” Steve Powell, HS2’s Head of Delivery said: “We’re now at peak construction in the West Midlands, and it’s great to celebrate the halfway point for the ‘Mary Ann’ tunnel drive into Birmingham. By the end of next year, both of these tunnels will be built, marking a significant step in HS2’s construction in the region. “Around 31,000 people are working on HS2, with around a third of these in the West Midlands including 615 apprentices and over 1,650 people who were previously unemployed, providing a unique opportunity for local people to learn new skills while delivering the UK’s largest construction programme.” Liam Byrne, Labour MP for Hodge Hill and Solihull North said:  “The extraordinary tunnelling under Water Orton and Birmingham is a world-class bit of engineering which would have made Matthew Bolton and James Watt proud. What is more, there are now more local residents working on the project than ever before. “HS2 is going to transform the economy of Birmingham and the West Midlands and the first trains will be running in just a few years’ time. What is now needed is the same genius that there is in this power of engineering to help us figure out how to bring down costs and drive up the economic benefits to the city and to Solihull.” The specialist tunnelling teams are from UK firm Tunnelcraft, and Solihull-based Rorcon, with a total of ten apprentices including formerly unemployed people from the local area who now have jobs on the project. Once complete, HS2 services will run between London and the West Midlands on a dedicated high-speed line before linking reaching destinations further north via the existing West Coast Main Line. It will provide significantly more efficient and faster journeys, while relieving pressure on the most congested southern end of the West Coast Main Line, allowing more local and freight trains to operate.

New footbridge to be built in Otley after public safety concerns raised over pedestrian crossing

New footbridge to be built in Otley after public safety concerns raised over pedestrian crossing

Last July after public reports of defects in the Otley Bridge walkway, Leeds City Council urgently investigated whether further repairs were necessary. After the specialist contractors inspected the underside of the current footway it found further hidden defects, leading to understand that these problems were more widespread and the decision to replace the footway. The council plan to install a temporary footbridge to allow residents with easy access to both sides of the river, whilst construction of a new footbridge takes place on the main bridge. This temporary bridge will be found a short distance to the east of Otley Bridge and link to Tittybottle Park. Otley Bridge is an ancient seven span stone bridge and Scheduled Ancient Monument, which is almost 800 years old and carries the B6451 over the River Wharfe, which links two halves of Otley town. In the 1950s a cantilevered pedestrian concrete walkway was added to improve safety, as traffic use grew. It is this walkway which is falling into disrepair with holes in the footway being covered by deck boards and rolling programme of inspections ahead of its replacement. Specialist contractor Balfour Beatty were appointed to look at solutions for bridge replacement and traffic management of the works. Initial work looked at all the options which saw pedestrians being diverted into the carriageway and single lane with temporary traffic lights for vehicular traffic. It was felt that any traffic restrictions in Otley town centre would be too disruptive, so a further contingency was developed to provide a separate temporary pedestrian crossing to enable the current traffic layout to be kept. If the council does not address the footbridge problems the deterioration will continue, with current mitigation finally becoming inadequate. This will eventually need a full closure of the walkway to pedestrians on safety grounds, and a lengthy pedestrian diversion or disruptive traffic lights to facilitate pedestrians on the road bridge. Initial activity is subjected to constraints of the site along a residential street and the geography. This will include some tree and vegetation clearance on the southern side of the river to create a temporary working area and launch site for initial piling works and to position a crane that will lift the bridge sections into place. In the park on the northern side minor works will also need to be carried out for creating a temporary abutment for the footbridge and to divert utility services. After the scheme, the council will plant several semi-mature trees for any tree which can’t be replaced like for like. The council will write to residents who live nearest the work site to further explain the works, and provide regular progress updates over the duration of the scheme. Residents and businesses will also be able to speak to the project team at the Otley Community Hub on  Nelson Street, starting in September on the following day/times: Tuesday 10 – 11am and Friday 1pm – 3pm. Subject to the weather, the scheme is anticipated to be completed during autumn 2025. Councillor Jonathan Pryor, Leeds City Council’s deputy leader and executive member for economy, transport and sustainable development, said: “Otley Bridge is an ancient crossing in the centre of the town. For pedestrian safety we now urgently need to demolish and replace the footway to modern standards, after coming to the end of its useful life. The new temporary footbridge will allow these works to Otley footbridge to be carried out safely, with less disruption to vehicle flow across the town and which will continue to enable people to cross the river safely. “The council considered a range of options which needed to factor for disruption, cost and timing of the works limited by planning, ecology and by the Environment Agency. By starting the construction of the temporary bridge now, means that the process of replacing the existing footbridge can start in spring next year. Unfortunately, there will be the need for some short-term disruption for access and noise, as we prepare the site for construction, especially to allow crane access to the site. “Vital work like this always involves disruption and best efforts are being done to minimise any as much as possible. However, I know that it will still be inconvenient for people, and I would like to thank everyone for their understanding and patience whilst we do this urgent work. The urgency requires some short-term inconvenience to construct the temporary bridge to continue to allow this vital crossing in the town. “We will keep residents regularly updated as the works progress and have set up a website (https://otleybridge.commonplace.is/) with information about the project, along with plans and timescales. The council will work closely with our contractor to make good progress over the months ahead, working towards an expected completion of the temporary bridge in spring 2025 and access to the new Otley footbridge in late summer 2025.” Building, Design & Construction Magazine | The Choice of Industry Professionals
