The production team behind the hit show had had a new steel balcony installed. They needed us to test the security of the mechanical fixings holding this in place before any of the production’s cast could perform on it.
This was a working show - with audiences on their way we needed to complete the work between the scheduled performance times and before that evening’s show. And the new balcony was situated on set so our team not only needed to work quickly but also with extra care, making sure they didn’t damage or move any of the iconic scenery.
We pull tested each of the 22nr bolts securing the balcony’s metal plates to the wall. To ensure safety for the actors, each fixing had to be able to take a load of 5.0 tonnes. This meant that every one had to reach an individual pull test of 5kN before they could be signed off as safe and fit for purpose. To load test them, we attached a clamp and jig to the protruding end of each bolt and pulled to the measure of kilonewtons required - a test they would either fail or pass. Luckily for the Les Mis crew, they all passed the test and we were well out of the way before curtains up. Bravo!
