Precast beam decks are generally used for short span bridges ranging between 5m to 50m – these may be railway or motorway bridges. Standard inverted tee beams or M-beams are chosen and positioned by crane. Where precast beams are considered for a motorway bridge construction, the bridge cross-section for a typical carriageway will generally consist of four beams. Erection time of such bridge should have a rate of construction of four beams per day. A cast-in-situ slab top deck is normally used with an expected rate of construction of one span a week.

🚧 Exploring Roller Compacted Concrete at Andale Construction 🚧 We're entering an exciting phase at Andale Construction with our latest project, which features Roller-Compacted Concrete (RCC). 𝐑𝐂𝐂 isn't just another paving method—it's potentially transformative for how we think about construction. 𝐖𝐡𝐲 𝐑𝐂𝐂? It's efficient, durable, and sustainable. We're seeing quick installation times, which helps meet project deadlines without a hitch, and the low maintenance is a bonus. 👷♂️ For the 𝐂𝐢𝐯𝐢𝐥 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐬 in our network, the technical aspects of RCC might be compelling. Its strength and endurance under heavy loads are noteworthy, especially in challenging environments. 🏗️ If you're a 𝐆𝐞𝐧𝐞𝐫𝐚𝐥 𝐂𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐨𝐫, the quick turnaround on RCC projects could be a game changer for your schedules and budgets: less downtime, labor, and more productivity. 🌆 And for 𝐑𝐞𝐚𝐥 𝐄𝐬𝐭𝐚𝐭𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬 looking for reliable and cost-effective building solutions, RCC offers a solid foundation for future developments that demand long-term resilience. We're genuinely excited about integrating RCC into more of our projects and are keen to see how it can help shape the landscape of modern construction. Are you curious about RCC or have insights to share? Let's connect and push the boundaries of what's possible in our field.

WSDOT recently completed two I-5 bridge projects with precast, prestressed griders over 220 ft in length. Designers share lessons learned from the erection of these extremely long and flexible girders at https://bit.ly/3TlycZ0

Great attention to detail in the precast bridge construction! The level of precision required is truly impressive. It's a reminder of the critical importance of accuracy in engineering.

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.

Looking to buy an #ICF home, but worried about extending it in the future?🏡 Fear not! When it comes to an insulated solid wall construction method like ICF, as long as you consult with a structural engineer, it should not be any more difficult to extend or remodel when compared to traditional construction methods. See the document below to find out more! #homeextensions #extensions #icf #icfa #structuralengineer

Did you know RCC is more cost-efficient than conventional concrete by reducing labor and eliminating rebar and formwork? That's right! By streamlining the construction process, we can slash both time and expenses, delivering projects faster and under budget. Plus, RCC's high durability and low maintenance needs mean long-term savings for your infrastructure investments. #rollercompactedconcrete #rcc #rollcon #concrete #construction #concreteconstruction 

PRECAST FOCUS: NOISE REDUCTION WITH PRECAST CONCRETE The inherent mass of precast concrete makes it an excellent unwanted sound or noise barrier. Noise can be isolated from rooms where it is not desired by utilizing precast concrete walls, floors and ceiling construction. Large reductions of noise levels from room to room can be accomplished only by continuous, impervious barriers. The ability of a barrier to reduce the intensity of airborne sound is designated by its sound transmission class (STC). As the unit weight of a precast concrete wall or floor increases, the STC also increases. STC ratings for various precast concrete wall and floor/ceiling systems are listed in this article: Learn more: https://ow.ly/L1iP50R2KRJ #precastfocus #howprecastbuilds
