LSJ Engineering built a steel staircase for Project Q at London’s Thames Barrier in autumn 2020.
- Client: Chisholm and Winch
- Modelled by: Mark Ebbs
- Job Duration: October 2020
Construction management company Chisholm and Winch employed us to design, supply and fit a steel staircase to the new Thames Barrier control building in south east London. The new Thames Barrier building was constructed by Balfour Beatty.
This was a simple stair, except that the half landing had to be radiused on-plan to match the RC (reinforced concrete) frame of the wall adjacent. Following an electronic laser survey of the curved RC wall, we built the stair to fit. Furthermore, Chisholm and Winch had to ensure that the build up of insulation and plasterboard, applied to the RC, perfectly matched the wall behind. We trial-built the stair at our works in Shoeburyness, Essex. This allowed us to check the rolled stringers were a perfect fit to the laser-cut landing plates, so all fitted the wall without gaps or clashes.
Once powder coated a rather bright yellow off-site, the stair was delivered and fitted without any issues!
What do you think of the finished product? We’re pleased with it!
