Assembling a temporary platform for a roof structure of a high 29 flour residential building with a safe workers access.


Project Type Commercial Building
Client AB "Montuotojas"
Completion Date 2017


  • Design and construct working platform of 3 meters height which will be standing on 29 floor (h~93m).
  • Assembled structure must cover entire working area.
  • Platform must be safe to work without height- climbers safety equipment.
  • Platform must support all weight from roof structure on assembling period.
  • The assembly of the roof structure requires high precision.
  • TG-60 towers were used as load bearing shoring system and at the same time as the base for the Allround system. This way we can make working platform around the TG-60 towers and all roof structure. Roof structure is protruding from building about 0.5 meters, therefore consoles were formed so that workers can go around all joints of roof structure. Consoles were protruding around 0.5 m from the sides and around 1.5 m in front. All scaffolding system was assembled in site. Firstly all the necessary material was lifted by crane to 29 floor and then assembled. H20 wooden beams were used for roof element support to scaffolding. For safe access to working platform two staircases were integrated in scaffolding structure.
  • Systems used: TG-60, Allround, Deck
  • Individual design
  • Cost-effective and practical complete solution from one source (design, material, workforce)
  • Short assembly time
  • Efficient execution and optimized on-site material requirements and organizational support provided by the same Prorentus project manager on the jobsite
  • Safe working scaffold and access points at all heights and on all working areas, fast and safe assembly of Layher scaffolding technology
  • Lower rental cost than traditional birdcage
