From the southern portal at Fortezza to the Brenner, there is now a tunnel that is 24.1 km long, part of the 64 km that will connect the Italian town with Innsbruck in Austria to create the Brenner Base Tunnel, which will become the longest railway tunnel in the world. This milestone was reached with the breakthrough of a diaphragm separating lots H71 Isarco River Underpass being built by Webuild and Mules 2-3 being built by Webuild and Ghella on the Italian side of the project.
Her Majesty The Queen visits Paddington Elizabeth Line Station ahead of the transformational Railway
Her Majesty The Queen and His Royal Highness The Earl of Wessex, visited Paddington Elizabeth line station to mark the completion of the transformational new railway ahead of its opening to passengers on Tuesday 24 May. During the Royal visit, Her Majesty officially unveiled a plaque to celebrate the completion of the line named in Her honour. The plaque will be permanently mounted at Paddington station, celebrating The Queen’s connection with the railway for generations to come.
Sika has opened a new plant in Santa Cruz de la Sierra, thus doubling its production capacity for mortar and concrete admixtures in Bolivia. With this new facility in one of the country’s main industrial agglomerations, Sika is positioning itself for continued growth in the dynamic Bolivian construction market.

All Units now in Service at Renewable Energy Keeyask Generation Megaproject in Canada
Keeyask hydroelectric station can generate up to 695 MW of clean electricity
The last of seven units have been placed in service at the Keeyask Generation Project, Canada’s newest hydroelectric power station. This is a major milestone for the project and the Bechtel-led team with Barnard Construction Company and EllisDon. Located in Manitoba, Canada, the project is a critical component to supply 4,400 GWh each year of clean, safe, and reliable energy, enough electricity to power approximately 400,000 homes.
“Keeyask has created jobs and opportunities for thousands of people since construction began in 2014,” said Dave Bowen, Manitoba Hydro’s director of Project Management. “As the fourth largest generation station in Manitoba, it will supply reliable, renewable power to our customers’ homes and businesses for decades to come, virtually carbon free.”
The project consists of a seven-unit powerhouse separated from a seven-gate spillway on the south side of Gull Rapids, all connected by three dams across the rapids. There are 23 km of dykes on the north and south side, with a total reservoir area of approximately 93 km².
The weather, topography, and the pandemic increased the challenges of the project. The power station was designed to harness the energy from the river with a per-cubic-metres-per-second volume twice that of Niagara Falls, at a project site located 10 degrees south of the Arctic Circle. Winter temperatures in the region could dip to below -40º C. Execution of the project was made possible by its committed team, including over 9,000 construction workers over the life of the project, and by employing innovative logistics measures and tools, including placing extreme-cold-weather concrete during the winter months. All sand, rock, and clay needed for the job was mined on site, including for the 334,000 m³ of concrete needed for the spillway and powerhouse structures.
“How we generate electricity is more important than ever before. The Keeyask Generation Project overcame many engineering challenges, balancing difficult construction conditions while abiding by stringent environmental guidelines,” said Kelvin Sims, Bechtel's Infrastructure general manager, Americas. “This impressive project was possible through ingenuity and tenacity of people that contributed to its completion.”
The Keeyask Generation project is a collaborative effort undertaken by the Keeyask Hydropower Limited Partnership – a partnership between Manitoba Hydro and the Keeyask Cree Nations, a partnership of four First Nations: Tataskweyak Cree Nation, War Lake First Nation; York Factory First Nation, and Fox Lake Cree Nation. The generating station is located on the Nelson River approximately 30 km west of Gillam, in the Split Lake Resource Management Area and within the ancestral homeland of the four partner First Nations.
Keeyask is one of the renewable and clean power projects that Bechtel is supporting to help customers on their path to net-zero emissions. Other projects include the Black Rock wind farm and the Cutlass solar farm in the United States, and floating offshore wind with Hexicon in the United Kingdom.
