Bid race begins for £1bn concrete road replacement deal National Highways has opened the bidding for a new six-year framework to deliver a major programme of concrete road replacement. Around 400 miles (4%) of England’s motorway and long-distance A-road network are concrete paved The new £1bn Legacy Concrete Roads Reconstruction Framework replaces the existing arrangement, which was more focused on repairs than reconstruction. Under the existing £400m five-year framework coming to a close, Morgan Sindall Construction & Infrastructure and John Sisk & Son Ltd are carrying out major reconstruction works, with lifecycle extension works are delivered VolkerFitzpatrick Ltd, COLAS, Dyer & Butler and Tarmac delivering life extension works. The next generation of framework will see a shift in spending focus towards full reconstruction and require around double the spend. Applications are due back in March with the new framework going live in November this year. The LCRR framework will be six years in duration to ensure alignment to and coverage of the RIS3 funding period (2025-30) but also to overlap with the beginning of RIS4 (2030-35). https://lnkd.in/dj-Y3uiU

#ThisisULMA   Are you planning your next bridge project?   Our innovative vision is based on a commitment to the most advanced technology, such as the balanced cantilever method, which consists of constructing the bridge deck, starting from the piers, with mobile formwork carriages. First, the first segment on the pier, known as the pier segment, is built on-site. The balanced cantilever formwork carriage supports the weight of the segment being built. Half of the structure is supported and fastened to the previous segment; the rest is cantilevered.   The most efficient solution for: ✅Bridges with spans up to 200 m. ✅There are riverbeds, intersections between several roads, and land where railways and roads converge simultaneously. ✅The pier heights exceed 50m.   System Advantages: ✅The work is performed in a reduced area on the deck and doesn’t interfere with traffic. ✅Flexibility: the ability to build decks with variable depths and distances between spans. ✅Hydraulic system for leveling and forward movement of the CVS carriage, reducing the labor force needed and construction times. ✅High load-bearing capacity: Larger segments can be made.   See this solution in the Bridge over the Grand River, in Ontario 👉 https://lnkd.in/gJ536RVf Learn more about this system 👉 https://lnkd.in/gHqe-NVq   #Civilworks #civilengineering #CVS #bridgeformworksystems #construction #bridgeconstruction #Formwork #ULMAConstruction #ULMAConstructionCanada

For the purposes of this thread the opinions I am expressing are my own personal views as an expert witness. Those of you who have followed the previous thread may now know that the battle to save Leazes Bridge in Durham has been lost. This is despite the presentation and multiple verification by one of the UK’s Experts on Reinforced Concrete, of overwhelming technical evidence in favour of repairing the bridge. The ramifications of the Local Authority decision to implement demolition have a long way to run over the next few months so I will not comment further. However again through a freedom of information request it was possible to obtain further heavily redacted Reports covering both Leazes and Baths Bridge which again have significant consequences. The same Consultant that appraised Leazes Bridge for the same Client drew the conclusion that Baths Bridge was also under strength by a very significant margin. The bridge has been subject to a width restriction to “prevent overload” despite the bridge having been repeatedly load tested for many years during the Durham Regata, since its construction in 1962. Myself and the same UK Expert have undertaken a peer review of the Baths Bridge Report. Unfortunately and very embarrassingly we have uncovered serious significant errors in the appraisal that are very basic in nature. If corrected these errors would then result in the bridge being correctly diagnosed with adequate strength. There are again errors in steel reinforcement strength [this time an inappropriate over estimate], but this is offset by major modelling and other errors. Baths bridge is now scheduled for demolition and replacement. How many more of the cities bridges are going to be condemned without sanity/second opinion verification with reliance on a single source inadequately checked appraisal? None I hope but the iconic Kingsgate Bridge must be overdue for an appraisal. Again I stress that this is my own personal opinion but it has been checked and sanctioned by a leading UK Expert. A joint Report as joint authors has been issued to the appropriate bodies. Further updates to follow.

SILVERTOWN TUNNEL CONNECTIONS COMPLETED Riverlinx CJV has completed construction works for the connections between the open cut approaches and the bored section of the Silvertown Tunnel. The final transition section of the tunnel was cast in Silvertown on April 11, completing the work to connect the northbound and southbound tunnel structures from the Silvertown portal to the Greenwich portal. A complete transformation of the tunnel shape was needed to connect the circular TBM-constructed tunnel to the in situ concrete arch-shaped cut and cover tunnels. To construct the four transitions, a self-propelled, self-erecting formwork was used, nicknamed “The Crab”. This 70-tonne tracked structure was moved into position and folded out to create the unique shape using hydraulic rams. The Crab then acted as a temporary structure for the installation of steel reinforcement before concrete was placed and allowed to cure. Once the concrete had cured sufficiently to be self-supporting, the machine folded the shutters inward for transport through the bored tunnel to the next transition location. The final of eight cross-passages is now ready for fit-out Read more online: https://lnkd.in/eU9R7shs Follow the British Tunnelling Society for the latest insight on tunnel-related matters To learn about the benefits of joining the British Tunnelling Society click here: https://bit.ly/3r0MPoU #BritishTunnellingSociety #civilengineering #undergroundconstruction #tunnelling
