Reinforcing stage floor at theathre

ÅF was given the task to temporarily reinforce the stage floor at the Intiman theatre in Stockholm.

In September 2014, ÅF was given the task to temporarily reinforce the stage floor at the Intiman theatre in Stockholm. Reinforcement was necessary because of a theatre production in which one of the characters falls into the water. 

Due to the floor's uncertain load capacity, it was decided that the specific area of floor would be reinforced. Initially, a pool that could accommodate 100 m3 of water on a surface of 100 m2 was requested for the theatre set. However, the volume was adjusted and decreased a couple of times to the final volume of 4 m3 on an area of approximately 6 m2.

The pool's location was to be on a circular, previously rotating part of the stage floor. There are two levels of concrete beams under the current floor part onto which the additional load could be distributed.

From ÅF's perspective, the assignment involved calculating and suggesting how the stage floor could be strengthened during the time that the production was running at the Intiman theatre. ÅF determined that it was necessary to temporarily reinforce the floor, and suggested using wooden pillars that could easily be cut to the correct lengths. The pillars were evenly distributed under the portion of the rotatable floor that carries the extra pool load.
