UK, November 25, 2017.- Large engineering works, public infrastructure projects, civil constructions with great economic impact, are one of my passions since I joined DOKA (2011). On this occasion, I highlight a very important bridge, both for the data of its construction, and for the benefits it will bring to the municipalities of both shores in the next thirty years. To remember all the details well, I turn to the information that Daily Record has published. By the way, the time-lapse recorded in the video is a great demonstration of the great work of construction professionals. In short, bridges are the best communication channels, complementing the digital channels. Next, the news of the Daily Record:
A symbolic new link between Aberdeen City and Aberdeenshire has been constructed over the River Dee as part of the AWPR/B-T project. The new River Dee Crossing now meets in the middle following the completion of decking works.Aberdeen’s new peripheral road is ploughing ahead with the latest segment a – new bridge over the Dee – now joined together in the middle as you can see in this time lapse video.
Work began on the crossing in summer 2015 but for the first time the decks from both riverbanks now meet in the middle, creating a new bridge between Aberdeenshire and Aberdeen city.The final piece of construction took place this year between June and September as part of the Aberdeen Western Peripheral Route from Balmeide to Tipperty. The bridge weighs 35,000 tons and will carry two lanes of traffic over the River Dee. The overall length of the crossing is 885ft with two back spans, each measuring 246ft and a centre span of 393ft. It was built using a cantilever forming traveller to create segments on each side of the hammerheads until they met in the centre. Around 200 people and 13 different nationalities have already worked 270,000 hours on its design and build.
The foundations reach to a depth of around 81ft so almost two-thirds of the structure is underground. It has been built using 31,400 tons of concrete sourced from the local area, 3237 tons of steel and 400 tons of post tensioning strands. Construction had to be carefully managed because of the nearby Special Area of Conservation. Measures in place at the River Dee Crossing include directing lighting away from the river and using construction plant with the least noise and vibration impact. Scottish Economy Secretary Keith Brown said: “We can look forward to the many benefits this project will bring when it opens to traffic. “It is expected to generate £6 billion and 14,000 jobs for the local economy over the next 30 years, as well as reduce congestion, improve journey time reliability and enhance safety.
