The CONCRETE Times ŭTVNNFS with the overall benefi ts of this system enabling faster, more effi cient construction by opening up lower levels sooner to the next phases of work. Another example which demonstrates the importance of a fl exible scaff olding system is the construction of tunnel works on the Farringdon Station Crossrail project. The construction method required a mobile scaff olding system within a tunnel of more than 8m in diameter to enable both waterproofi ng and spray concrete lining. The scaff old design also required access for trucks to enter the tunnel so that concrete work c ould run simultaneously. With safety and stability at the forefront of the design, one of the main challenges was to meet Prestec’s preference for a castormounted scaff olding structure which signifi cantly restricted the system weight available to us. At the same time, this also had to enable the contractor to conduct concrete spray lining using a system that was suffi ciently narrow to move freely within the tunnel. In response, our design team in Brentwood were able to design a bespoke PERI UP system with detachable cantilevered console brackets on the edges of the structure to allow waterproofi ng to take place. Once waterproofi ng was completed, the brackets could also be utilised for the concrete spraying which enabled the work to be completed in a shorter period of time. An additional example of the compatibility and ease of integration between PERI UP and formwork systems can be seen in the construction of escalator shafts. By utilising a formwork base frame within a sloping construction site and mounting mobile PERI UP scaff olding system on this base, a fl exible and cost-saving mobile platform aids a quick and safe construction process. Having an integrated solution provided by a single supplier can help to ensure that critical activities in complex construction projects go ahead as planned. Conversely, introducing additional suppliers creates additional challenges for contractors, which may impact on smooth running of a project. Unnecessary risk cannot be countenanced, while integrated solutions can help to deliver greater effi ciencies in terms of time, cost and logistics, while also helping to achieve improved worker safety.
