HS2 hails big carbon saving on Colne Valley Viaduct project.

The team designing and constructing the HS2 Colne Valley Viaduct project are on track to cut embedded carbon by 28%. Narrowing the width of the viaduct has conveyed a great reduction in carbon across the 3.4km viaduct structure, planned to be the longest railway bridge in the UK. The concrete and steel reduction on the scheme helped to slash embedded carbon by 63,300 tonnes CO2e , equal to 234,500 flights from London to Edinburgh. The HS2 Colne Valley Viaduct main works contractor Align JV which is a joint venture made up of Sir Robert McAlpine, Bouygues Travaux Publics, and VolkerFitzpatrick toiled for four years on designing with architects Grimshaw together with design partners Jacobs and Ingerop-Rendel. Starting from the reference design produced as section of the HS2 parliamentary process, they perfected the design, challenged assumptions, and found efficiencies to help lower the amount of steel and concrete in the HS2 Colne Valley Viaduct. This comprised working closely with rail systems specialists at HS2 to let the structure get narrowed by over 1m, while still allowing sufficient area for signalling and control equipment alongside the line. Inside the viaduct, the engineers decided for a ‘post-tension’ design, with lightweight super-strong steel cables stretching on the full length of structure. United Kingdom

Namibia Prepares Bidding For the CSP Project in 2022

NamPower generation projects chief Grant Muller put up the national power company’s now-finalized plans for a CSP project in Namibia, ranging from 50 MW to 130 MW including storage, at the 2021 SolarPACES Conference. It is set for its first CSP auction in 2022 after four years of preparation. Namibia possesses some of the world’s greatest solar resources, with DNIs as high as 3214 kWh per square meter per year (3,214 kWh/m2a). Its current installed capacity is 680 MW, which serves a population of 2.5 million people. Nearly all (517 MW) is provided by renewables (hydropower, solar PV, and wind). However, a tiny fraction (122 MW) is still supplied by coal, and it now obtains power from the coal-heavy grid of neighboring South Africa. Its goals are to reduce reliance on imports and coal and improve the resilience of its renewable grid. Namibia

The WestConnex project in Sydney Australia.

WestConnex is a 33km predominantly underground motorway project in Sydney, New South Wales, Australia. The project is partially completed and other parts still under construction. Being a joint scheme of the New South Wales and government of Australia, the motorway project will include around 26 kilometres of new tunnels from Homebush to Kingsgrove, stretching underneath Inner West suburbs through Haberfield and St Peters. The WestConnex project is split up into three stages: Stage 1: M4 Widening and M4 East The work comprised of widening of the old M4 Western Motorway from two or three to four lanes in both direction from Parramatta to Homebush Bay Drive; and the M4 East, new two, three-lane motorway tunnels from Homebush to Haberfield, joining to the City West Link. Stage 2: St Peters and King Georges Road Interchange, M8 Tunnel Related Posts: The Delhi–Mumbai Industrial Corridor Project Timeline. The Melbourne Metro Tunnel Project Timeline Bangabandhu Sheikh Mujibur Rahman Tunnel, the first underwater tunnel in South Asia The St Peters Interchange, developed at the eastern end of the M8, is a viaduct road interchange that joins the WestConnex with local arterial roads like Euston Road and Gardeners Road. It will also link to the proposed Sydney Gateway towards the Aiprport. Recreational areas are provided around the interchange. Furthermore, Campbell Street and Campbell Road in St Peters was to be extended and widened eastwards over Alexandra Canal and connect with Bourke Road in Mascot. A recreation parkland was to be constructed aligned with the Campbell Street. The existing M5 interchange at King Georges Road was to be upgraded and a new M8 Motorway built with a new set of tunnels from the M5 at Beverly Hills to St Peters. The M8, also reffered as the New M5 during the planning and construction, was also designed to offer future connection to the proposed M6 Motorway. Stage 3: M4–M5 Link, Iron Cove Link and Rozelle Interchange Stage 3 comprised of constructing M4–M5 link, a modern motorway tunnel linking the M4 East and the M8; the Rozelle Interchange, an interchange underground at the site of Rozelle rail yards directly connecting the Anzac Bridge and Iron Cove Link, a kilometre tunnel between the Rozelle Interchange and Iron Cove Bridge bypassing the congested Victoria Road corridor.

CTA plans to begin $2.3 billion Red Line Extension Project in Chicago

The Chicago Transit Authority(CTA) is working towards breaking ground soon, on a long-awaited $2.3 billion Red Line Extension Project at the Far South of Chicago. The CTA Red Line Extension project is aimed at easing commuting around the city, by extending the Red Line train route 5.6-miles to 130th Street and also building four new stations, equipped with bus and parking facilities; these four stations will be located at 103rd Street, 111th Street, Michigan Avenue, and 130th Street. Besides reducing the transit time of bus riders commuting from 95th Street to the Far South Side, this project will also bring future economic development to the city, by providing over a hundred jobs in the course of the development and also creating a faster link to jobs and other opportunities, located along the extension route.
