Steel Staircase at Project Q, Thames Barrier, London

LSJ Engineering built a steel staircase for Project Q at London’s Thames Barrier in autumn 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. Balfour Beatty. constructed the new Thames Barrier building.

This was a simple stair… except that the half landing had to be radiused on-plan, in order to match the reinforced concrete (RC) frame of the adjacent wall. Following an electronic laser survey of the curved RC wall, we built the stair to fit. Furthermore, Chisholm and Winch needed to ensure that the build up of insulation and plasterboard, applied to the RC, perfectly matched the wall. Bearing this in mind, we trial-built the stair at our works in Shoeburyness, Essex. This allowed us to check that the rolled stringers perfect fit the laser-cut landing plates, and fit 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? Although a complex job, our team worked brilliantly to ensure we fulfilled our brief.
